Yes, first value correlation is there, but old formulae have even worse effect "The random sequences do not vary much with the seed", as source file comments and whole discussion about old RNG bad effects shown. I.e. = =20 for different time+PID sequence, especially increased monotonically, like in common practice, you'l got the same random sequence with old formulae (which can't be called "works fine" because this fine work was the main reason for change). So, returning to old formulae is not an option. The real problem is not in formulae, but in srand() funclion. This simple patch can fix first value correlation, and I plan to commit it, if we all agree. I not find better value for NSHUFF right now, but think that something like 10 will be enough to fight corellation completely. Some generating picture tests needed. --- stdlib/rand.c.bak Sat Jan 4 20:39:19 2003 +++ stdlib/rand.c Sun Feb 2 11:56:01 2003 @@ -51,6 +51,8 @@ #include #endif /* TEST */ =20 +#define NSHUFF 3 + static int do_rand(unsigned long *ctx) { @@ -103,7 +105,11 @@ srand(seed) u_int seed; { + int i; + next =3D seed; + for (i =3D 0; i < NSHUFF; i++) + (void)do_rand(&next); } =20 =20 @@ -117,7 +123,7 @@ void sranddev() { - int fd, done; + int fd, done, i; =20 done =3D 0; fd =3D _open("/dev/random", O_RDONLY, 0); @@ -133,6 +139,8 @@ =20 gettimeofday(&tv, NULL); next =3D (getpid() << 16) ^ tv.tv_sec ^ tv.tv_usec ^ junk; + for (i =3D 0; i < NSHUFF; i++) + (void)do_rand(&next); } } =20 --=20 Andrey A.

Another problem (noticed by tjr) is that once the sequence hits '0' it jumps to INT_MAX and stays there forever. For example, seeding with srand(0) produces nothing but INT_MAX from rand(). It looks like a lot more validation of this PRNG is needed.

As I see searching through various sources, this is not simple overlook but fundamental feature of this formulae - it can't be initialized with zero and BSD developers try to deal with that fact by simple adding of INT_MAX in zero case (which is not in the original formulae), but gain nothing this way. Workaround I find so far is something like that #define MASK 123459876 seed ^=3D MASK; =2E.. calculate value ... seed ^=3D MASK; Which just add another magick value, but fix zero.=20 I am still searching... --=20 Andrey A.

Throwing away the first 10 numbers is probably not good enough to eliminate randomness with respect to the initial seed. Knuth suggests throwing away the first 2000, but he is conservative.[1] But no amount of throwing away the initial sequence will help as long as the generator itself doesn't look very random. Specifically, rand() isn't very interesting in the lower-order bits, and it spectacularly fails nearly all of Marsaglia's randomness tests.[2] If rand() is a concern to someone, they should either find LCG parameters that produce better behavior, or research a replacement algorithm.

From: Poul-Henning Kamp Date: Sun, 02 Feb 2003 12:57:56 +0100 Message-ID: <58894.1044187076@critter.freebsd.dk> This is _only_ about the driver for the DiskOnChip devices from M-Systems. This does not affect any other device. If you have never seen a /dev/fla0 mounted on your system, you don't need to read the rest. I realize that there are users of the DiskOnChip hardware out there now, but I seriously don't expect there to be any users once we get to FreeBSD 6.0 so I plant to remove the driver once the 5-stable branch is laid down. This means that the 5.x series of FreeBSD releases will be the last to have built in support for the Disk-On-Chip driver. The driver in the tree works with the M-systems devices I have to test with, but M-Systems have neither sent me the necessary software updates nor hardware samples of the latest generation of the DoC and I have received no emails from people who were stuck because of this. Combine this with the fact that the DoC is a CPU-poll technology where you busy-wait for the flash devices to do their thing, rather than get an interrupt when they are done, I think we can safely say that the DoC is well past its prime time. As far as I can tell, people use CompactFlash these days instead.

Yes. Nothing better is possible for this formulae and this is documented in algorithm, some value must be excluded. Excluding 0 is bad only because srand(0) is commonly used and srand(123459876) is not. Ragarding to old formulae, the question is: what is worse, generate non-random lover bits everytime (old variant) or exclude one seed value (new variant)? Of course formulae can be changed to some another algorithm, but keep in mind that rand() must be simple and speedy. Now used variant is most simpler, others are much more complex. -- Andrey A.

I've had some problems with CardBus cards on boot not probing, but that's a different problem that I'm aware of and working on a solution for and has nothing to do with devd.

This workaround can be improved more, to make generator not stuck ever with 123459876 by simple way: if (seed == 123459876) seed = 123459877; It can be done even with original variant using more simpler patch: if (seed == 0) seed = 123459876; I'll produce and send it a bit later. -- Andrey A.

The source tree doesn't work like ports, where "make install" will do all the prerequisite steps first.

I dont know for Userland though, sorry= =2E With userland, you're left tweaking CFLAGS and CXXFLAGS in /etc/make.conf. Here's a few things you might want to consider: - Removing any reference to '-g' (Debug symbols). - Adding -O or -O2 (Code optimizations). Use of -O3 is not a good idea. - Adding CPUTYPE=3Di686 (or whatever is appropriate for your machine) will enable cpu-specific optimizations. Once you've made these changes, recompile and install world. A mergemaster would probably be in order as well.

After cvsupping several times to an avail, I deleted the new kernel build. i.e. I deleted my kernel file and its directory (the one created when you do config ), copied generic to a new kernel file, added my own configs, and did a a new config and the whole thing worked again. That was yesterday. Assuming you have added the proper configuration in your kernel.

I ran into a similar problem, actually -- programs like dhclient rely on being able to write to lease and pid files. It's almost as though we'd like an additional set of events when the system is "more booted". I.e., a devd event for each device when the network is started, etc. Actually, I suspect what we want is to have a seperate network event management daemon -- arrival of the device is not the same as arrival of the interface. dhclient events (and related things) should happen as a result of the interface arriving, not the newbus device arrival. I.e., a netd that listens to routing socket and kqueue events relating to the network stack.

Well, it did not really help to put a "sleep 20" at the beginnging of my script, it did help anyhow to put a put a "sleep 20 ; " in front of the script execution in the attach line. So I know now, the script actually get's started. Although it's a viable way to have the sleep in the attach line, this is clearly not a good solution: I do not really know, how long the system needs for booting to a stage, when the script can be executed. And I don't really want to wait 15 or 20 seconds everytime I insert the network card before the script actually beghins to work. OK, I get around it, as I usually don't exchange network cards too often. So maybe there should be for devd the possibilty to delay script execution for some time or better until a certain event for the booting case.

I installed "compat4x" to use our existing 4.x binaries. Immediately after rebooting, I noticed most old 4.x binaries were complaining about "_stdoutp" being an undefined symbol. However, the scary part was that when I started apache/mod_php4 the server crashed (hard lockup) within 10 seconds under load. This was easily reproducible, at least a dozen times while trying to debug this I started httpd, and the server locked up within 10 seconds. I recompiled all of apache, mod_php4 and all of its libraries, started up httpd and had no problems with that. Things were fine that night until an "analog" cron job ran, every time THAT ran, I also got a hard lockup of the server, OR between 100 and 500 of my httpd processes would suddenly SEGV. After a little more poking around, I saw in /usr/lib: lrwxr-xr-x 1 root wheel 9 Feb 1 00:18 libc.so -> libc.so.5 lrwxr-xr-x 1 root wheel 16 Jul 5 2002 libc.so.3 -> /usr/lib/libc.so -r--r--r-- 1 root wheel 571480 Aug 5 13:45 libc.so.4 -r--r--r-- 1 root wheel 836892 Feb 1 00:18 libc.so.5 Shouldn't libc.so.4 have been a symlink to libc.so after a compat4x install? In any case, doing that myself seemed to fix everything. My questions: 1) Shouldn't something along the way of doing a sysinstall upgrade or installing compat4x have fixed /usr/lib/libc.so.4 into a symlink? (That is the correct situation, right?) 2) Is it possible that some kernel interface has changed, and something isn't being validated in the kernel side? Non-root userland applications being able to lockup the server, and/or affect other processes simply by using a different libc would seem to indicate this. I know this is a pretty vague bug report, but this is a production server, so I wasn't able to play around too much with it. I do have a backup of the entire server before it was upgraded to 5.0 if you'd like me to check anything there. I did compile with INVARIANTS and WITNESS and got no debugging output when things did lock up. The keyboard and serial console were totally dead when this happened, so DDB isn't an option either.

In any case, doing that myself seemed to fix everything. No, this would cause you major problems. Binaries that expected the libc.so.4 interface would be calling into libc.so.5, and probably causing very strange behaviour. Cheers, -- Jacques A. Vidrine http://www.celabo.org/ NTT/Verio SME .

Ok, I admit, no matter how it happened, an application using the wrong libc is a bad thing. But, how are things supposed to work? Apps that were using the old libc.so.4 complained about unresolved symbols(_stdoutp usually). If I removed /usr/lib/libc.so.4 they complained that they couldn't find libc, If I did create link libc.so.4 to libc.so.5 everything appeared to work just fine, but I know that's probably a fluke. In any case, a system lockup or being able to crash other user's processes just by having the wrong libc shouldn't be possible no matter what happens.

Well, things were definitely picking /usr/lib/libc.so.4 over anything in compat. Should sysinstall have nuked my /usr/lib/libc if it was putting the correct one in compat? > In any case, a system lockup or being able to crash other user's processes > > just by having the wrong libc shouldn't be possible no matter what happens. > >Probably not, although if you have processes running as root and using >the `wrong' libc, all bets are off. Well, after I recompiled httpd (which did have a single process owned by root) and rebooted, nothing at all owned by root touched anything that was compiled under 4.x. Non-privileged regular users owned the process owned by analog, which caused the same behavior. Me running analog under my normal account could kill processes owned by "nobody" with segfaults.

BTW, if we ever think about replacing our current variant with such complex and unknown (at least to me) thing as RC4-based PseudoRNG, I simpatize more to Knuth variant mentioned by David Schultz: http://www-cs-faculty.stanford.edu/~knuth/programs/rng.c RC4 is good for hashing existen randomness, but is it good as PseudoRNG? -- Andrey A.

It's almost as though we'd : like an additional set of events when the system is "more booted". I.e., : a devd event for each device when the network is started, etc. That might make sense. Part of the problem is that while the system is booting there is only some vague notion of system state once you get to init. Part of the problem also is that devices have no information about what type of device any given device is. There's no way that one could "hold in abeyance" those devices that are network devices because we have no clue what a network device is and what isn't. It gets muddier when devices have multiple uses. Is sio a network device? If it is used for a ppp link it is, but if it is used for a serial console it isn't... : Actually, I suspect what we want is to have a seperate network event : management daemon -- arrival of the device is not the same as arrival of : the interface. dhclient events (and related things) should happen as a : result of the interface arriving, not the newbus device arrival. I.e., a : netd that listens to routing socket and kqueue events relating to the : network stack. Trouble is that "network interface arrival" is the same as "device arrival" The network interface is attached in foo_attach() so that's not a better time to do things because it is the same time. Since it happens in foo_attach, it actually happens before the device is entirely attached to the tree, so you are suggesting doing something that happens earlier :-). While carrier detect might be slightly better, it still is insufficient because that usually happens before init is run too. If it was that easy, I'd do it. I'm still trying to find the best place to start devd. Right now it starts before everything else. Maybe it needs to start just after the network starts, but that's arbitrary. That would ensure that we have a writeable /var for dhclient, but might preclude other interesting uses for devd. One could also make a case for just before network starts too. Doing it after means that one only has to put the 'don't configure it again' check into one place rather than two. The one in the second place has generated some problem reports that I need to look into. Part of the problem too is that we're now doing the configuration of devices in two places. Network devices are the only ones where we do interesting things with, but I think that we're seeing growning pains introducing dynamic things into a formerly static system. It is little different than when pccard and dynamic device loading was added to the kernel...

What form RC4 distribution have? (I have read the whole thread) I think we need four things. 1) void srandom(int arg) which uses the argument to seed. 2) void srandomdev(void) which uses system entropy to seed. 3) int random(void) which returns a number statistically random in all bits. 4) which returns as many bytes of randomness (statistically random in all bits) as the caller asks for. We have most of this, and RC4 can deliver. RC4's "licence" is fine. Call it "ArCFour" and there is no problem. The code is small, fast and repeatable, and meets conditions 1-4 above. Coding is Junior-high-school level, given the spec.

Our manual pages do not comprehensively list all compatibility concerns or concessions, waving our manpage about does not address the concern. As I said, I don't know how big a concern this is. But last time it was enough of a concern to make us keep rand() as it was.

There are some concerns about RC4's strength and predictability. In cases were we just want trivial "randomness", this doesn't matter, but when we start to seed it with /dev/random to get good randomness we to be more careful.

If you go change the underlying algorithm or its parameters one can't generate the same sequence from the same seed when repeating a test. Some chip bug symptoms show up after hours/days of simulation time and only with specific inputs so repeatablity is a requirement. The old 16 bit rand() was broken enough that it didn't matter much (read: _I_ don't care) if its behavior got changed but random() has a pretty long cycle and enough "randomness" to be very useful and it *is* used. *Please* don't change random() -- if you do that you will break existing tests. It is not a matter of just rewriting tests since there is no easy way to predict which input triggers a certain bug -- one can try to use the same binaries but that prevents fixing of bugs in the test generation code itself. If you think random() is not random enough for your purposes, go create a new function with a *new* name.

That why I say we need to run some tests to compare RC4 distribution and other vital parameters with our current variant. The worst case will be if we replace good PRNG with bad. F.e. Knuth variant I already mention already proven as better than what we currently have, so don't have such problem as RC4-based PRNG probably have. -- Andrey A.

Heisenbug. Which tests do we break? Tests for specific output, or tests for more general cases? The random() function in libc is documented to give the same pseudo-random output for a particular seed. if you link your program against a _different_ libc, you cannot expect your results to follow a particular number sequence. We have to be able to fix bugs, and a bug has been identified. If you want a stable generator here, link statically, and keep a set of compatiblity libraries around. > If you think random() is not random enough for your purposes, > go create a new function with a *new* name.

Since you have custom configuration, it might rely on other parts of the system being active before they will work. This patch moves devd from starting 'first' to starting before we have to mount the 'critical' remote disks. If you require critical remote disks to depend on devd, I might need to make a couple of changes to devd to call daemon after it has done the configuration actions for devices that match, but this should work for those people that use, say, /usr/local/bin/perl. There's also a couple of "fixes" to network1 that I can back out with these changes.

I'd support that. People who are using rand and random for crypto type randomness are deceiving themselves, as neither are portably suitable for that use. Lots of people are using rand, random and the rand48 suite for simulation or games, and this type of randomness has different requirements (as Bakul points out - repeatability being a useful one). I'd suggest we ammend the rand and random man pages saying that sequences produced from either cannot be expected to be suitable for cryptographic purposes, but are should be OK for simulation and games. (I guess a couple of numbers produced after calling srandomdev might be safe, but I wouldn't like to bet on them being that safe...) The man page can refer people on to arc4random, the apropriate OpenSSL pages, uuidgen and so on. As different consumers have different, sometimes contradictory, requirements for "randomness" it seems foolish to try to lump them all into one group of functions. David.

Maybe I missed something, but why cannot you just rip random() from libc, rename it to bakul_shah_random() and use that in your testing code? Then you are safe from any changes to random(), and indeed have a portable RNG if your host OS changes. Regards, Edward.

We should separately document (or at least clarify) the differences between cryptographic randomness and statistical randomness. We should also make sure that both are bug-free. Cast-in-stone algorithms are dumb, but if you really want those, its probably best to put them in your own code.

So create a new function! Or use a different function to generate or initialize the seed. I think one has to treat a behavior bug very carefully. If enough people are depending on it, it pretty much has to get enshrined as part of the spec -- sort of like the timeout arg to select(). > The random() function in libc is documented to give the same > pseudo-random output for a particular seed. if you link your > program against a _different_ libc, you cannot expect your > results to follow a particular number sequence. There is an expectation that on subsequent releases of the same OS things continue to work. Historically rand() and random() under unix have been used the most for simulation. [aside: Earl T. Cohen (the author of random(3)) also has had a lot to do in this area] Why not totally separate all uses of crypto related random number generator uses from the traditional simulation use? That way you can change crypto_random to your heart's content as the crypto needs change (as they will). -- bakul To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 12: 5:34 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 6A4E837B401; Sun, 2 Feb 2003 12:05:32 -0800 (PST) Received: from salmon.maths.tcd.ie (salmon.maths.tcd.ie [134.226.81.11]) by mx1.FreeBSD.org (Postfix) with SMTP id 3CC4C43FAF; Sun, 2 Feb 2003 12:05:31 -0800 (PST) (envelope-from dwmalone@maths.tcd.ie) Received: from gosset.maths.tcd.ie by salmon.maths.tcd.ie with SMTP id ; 2 Feb 2003 20:05:30 +0000 (GMT) To: Mark Murray Cc: Bakul Shah , "Jeroen C. van Gelderen" , phk@FreeBSD.ORG, current@FreeBSD.ORG Subject: Re: rand() is broken In-reply-to: Your message of "Sun, 02 Feb 2003 19:43:14 GMT." <200302021943.h12JhEaX050421@grimreaper.grondar.org> X-Request-Do: Date: Sun, 02 Feb 2003 20:05:29 +0000 From: David Malone Message-ID: <200302022005.aa62194@salmon.maths.tcd.ie> Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG > > I presume it also produces reasonably uniform output for most > > seeds too. > Yes.

Is convergence-to-constant OK? While we have no obligation to keep our implimantation constant accross between versions of libc, it may be a pain for users if we change the implimentation. We should just consider that before we decide to make a change. If it our change really is an improvement for most users, then it may be worth making anyway.

Indeed, that's what I've done when I really want portable repeatibility. Infact the old crappy rand() implimentation had some interesting interactions when used when one of the MSc students here used it to test some of the AES candidates.

I think there is more than one level of 'compatibility'; I for one would not expect random() to return the same results across platforms, certainly, or even between seperate releases of one platform, even though its API may be the same. For two reasons, mainly, the first that you know someone will change it somewhere anyway ;-), and second I think that's placing too much of a restriction on the OS. If FreeBSD makes random2() using RC4 to avoid changing rand() or random(), will people then start relying on random2()'s behaviour, and when someone finds a problem in RC4, then the next will be random3()? If you require implementation of random(), then I don't think that it's so bad that you should be expected to provide it yourself, rather than assuming this is what the OS uses. But then maybe this comes down to difference of opinion. Would you have a problem with changes in the TCP/IP stack changing the content of packets sent out when you connect(), if it breaks your TCP/IP simulations? Regards, Edward.

About correlation bug: it is srand() which is broken, not rand(). It is common practice for this type of PRNGs to throw out N values after seeding to remove correlation and srand() not follow this.

If your program depends on the exact algorithm used by random() (or rand() for that matter) to not change between OS updates (not to mention between different systems) then that is a bug in your program. The interface will not change just because a different algorithm is used. The exact sequence of random numbers produced is not a part of the interface but rather an implementation detail that portable programs should not depend on. It might also be worth noting that if a good PRNG is needed then one should not use random() or rand() since on some systems their output is not very random. -- Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 12:52:57 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 2DEB437B401; Sun, 2 Feb 2003 12:52:56 -0800 (PST) Received: from obsecurity.dyndns.org (adsl-67-115-74-80.dsl.lsan03.pacbell.net [67.115.74.80]) by mx1.FreeBSD.org (Postfix) with ESMTP id 56FE243F85; Sun, 2 Feb 2003 12:52:55 -0800 (PST) (envelope-from kris@obsecurity.org) Received: from rot13.obsecurity.org (rot13.obsecurity.org [10.0.0.5]) by obsecurity.dyndns.org (Postfix) with ESMTP id C287167C6F; Sun, 2 Feb 2003 12:52:54 -0800 (PST) Received: by rot13.obsecurity.org (Postfix, from userid 1000) id 9E4E2963; Sun, 2 Feb 2003 12:52:54 -0800 (PST) Date: Sun, 2 Feb 2003 12:52:54 -0800 From: Kris Kennaway To: Bakul Shah Cc: Mark Murray , "Jeroen C. van Gelderen" , phk@FreeBSD.ORG, current@FreeBSD.ORG Subject: Re: rand() is broken Message-ID: <20030202205254.GC74654@rot13.obsecurity.org> References: <200302021908.h12J8laX050048@grimreaper.grondar.org> <200302021955.OAA20742@glatton.cnchost.com> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="f0KYrhQ4vYSV2aJu" Content-Disposition: inline In-Reply-To: <200302021955.OAA20742@glatton.cnchost.com> User-Agent: Mutt/1.4i Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG --f0KYrhQ4vYSV2aJu Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable On Sun, Feb 02, 2003 at 11:55:25AM -0800, Bakul Shah wrote: > > RC4 is _utterly_ repeatable, given a particular seed/key. >=20 > May be but it is not the same as the current random().

If you guys had left the original rand() alone we wouldn't be discussing any of this.... random(3) also provides an initstate() call which presumably allows you to change the amount of randomnes. So here is another suggestion: why not fold your algorithm change in that function? For example, initstate(seed, "RC4", 3); changes the algorithm to RC4. Yes, this is a change in the interface but one I am sure most people can live with. > > There is an expectation that on subsequent releases of the > > same OS things continue to work. > > Where is that expectation guaranteed? > Where is that expectation supported? This expectation is a reasonable one. Most commerical OSes do a good job of maintaining compatibility. IRIX certainly did a pretty good job of it. FreeBSD also does a pretty good job on the whole. > The two are related topics.

If an os provides a function, that function should be as good as possible while not breaking standards. We have lousy functions like gets(3), that we have to keep because the standards say we do and programmers keep on writing code that uses them. rand() and random() have a docimented interface, and empirical programmer expectations about their outputs simply result in bad code. > > > There is an expectation that on subsequent releases of the > > > same OS things continue to work. > > > > Where is that expectation guaranteed? > > Where is that expectation supported? > > This expectation is a reasonable one.

You have allowed us neither in the 17 minutes you waited between posting this patch and committing it. If I had to guess, I'd say that you're eager to fix the mistake you made, and I suppose that's commendable. However, it's been broken for two years, it can wait another couple days for a more thorough fix. Doug -- If it's moving, encrypt it.

The point of compatibility is to > not break interfaces unless there is a significant benefit. I can think of one significant benefit... I had noticed that my perl script to pick random windowmaker themes (which uses rand()) seemed to be picking the same themes over and over again. Now I know why. :) I had to create a "last seen" list to artificially increase the "randomness." Oh wait, TWO benefits... xscreensaver is having the same problem. Seriously though, I think the (vast?) majority of our userbase expects random (or even pseudo-random) numbers to be, well, random. For a sufficiently naive definition of random anyway. While I can certainly sympathize with your needs here, with all due respect I think it's an edge case, and one that could be handled with a little customization on your part. Even if you didn't want a code solution, you could spool off BIGNUM "random" numbers from whatever source you choose and save them to disk so that you could get 100% repeatability. Your needs have more than one solution, but I don't think that depending on rand[om]() not to be random is a good one. Doug -- If it's moving, encrypt it.

Uhm, I don't understand you well here. Any code can have strange problems, nobody can be sure. Lets concentrate to this particular problem which I call 0 problem. 0 seed is illegal by algorithm desing and BSD developers try to made workaround, but their attempt was unsuccessful with result you describe. Now successfull attempt comes. It not add any new bugs, because value 0 simple mapped to another value (which could be any, but I choose to not touch lower ones), which make generator non-stick at 0 again. --=20 Andrey A.

This or a similar change is upward compatible in that the existing behavior is left unchanged and it gives you a way to replace the algorithm. The basic issue is just what is the expected and (implicitly) promised behavior of random(). AFAIK all random(3) implementations in various versions of Unix come from Earl's original 4.2BSD implementation so in my view the _expected_ behavior is to see the _exact_ same sequence starting from a given seed. This function is called "random()" but it is equivalent to a mathematical function which must provide the same sequence for the exact same input. You and a number of other people are saying that the exact sequence is *not* promised so you are free to change the algortithm as long as the statistical distribution is uniform. Earl chose to name his new implementation random() [even though clearly he was replacing rand(3)] probably to not break any existing scripts. In my view any further behavior change should either use a new name or make an upward compatible change. Now the question is whether perl uses system provided random() or rand() or its own since perl is used extensively in ASIC verification. Any way, this is my last email on this subject since neither one of us is convincing the other.

GBDE is the first user of what can only be described as a very green config-API for GEOM classes. One idea I have almost convinced myself to implement, despite its unUNIX like nature is to include a char erortext[256] in the request package because the idea that all errors have integer numbers gets old really really fast with the rather complex conditions some of the GEOM modules test for: return (EYOUARESHRINKINGAPARTITIONWHICHISOPEN) I think not :-) -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.

Not quite. Close. You compile program on a machine with a constant argument to srand[om](). Run the more than once, and rand[om]() will give you the same sequence.

If I understand correctly, this still doesn't solve the problem, because any PRNG sequence that hits the "magic" value will still get stuck there forever.

In theory, its cycle-of-repetition is 2^(8*256) bits. The current library PRNGs are quite a bit less than that. > 2) Implementing rand(3) with RC4 can be possible only if seed (i.e. > state) can be stored in single word (due to rand_r()) restrictions. This is true. Sort of. But in this case, things get less easy. Hmm. I need to look at this some more. Thanks!

That's why randomness tests + mathematician to interpretate their results are needed to compare what we have now in random(3) with RC4. Easy and understandable code not always mean better results.

If you need guaranteed reproducible random numbers that won't change from system to system or across libc versions, you need to roll your own PRNG. A simple linear congruential generator such as the original BSD algorithm might look random enough for your purposes. But I must admit that I was surprised when Andrey Chernov pointed out that rand() had been replaced between -CURRENT and -STABLE; I thought it was simply common knowledge that rand() was broken, and nobody was interested in fixing it.

Actually, RC4 is well understood (and trusted). LCRNG's are considered less good in comparison with cryptographic techniques.

The SunOS output exactly matches random(3) behavior from 4.3BSD! In fact random() remained the same for 4.3BSD-Reno, -Tahoe, 4.4BSD-Alpha and Net2. 4.2BSD random() behavior is different from all of the above. There was real bug-fix between 4.2BSD and 4.3BSD. I don't know when the FreeBSD/Redhat change was made or if it broke any statistical properties.

Please Mark, just leave rand(3) and random(3) alone -- other than to fix the single bug Kris reported at the start of this thread. Long-time Unix users expect them to work as they do now. The manpages state they are not cryptographically random. If someone wants a function of that type we have a good arc4random(3).

The same objections I always raise when someone replaces a PRNG that allows repeatable results with old software with a new one, that does not, I guess. BTW: if /dev/random is so damn good, why are you using it as an implementation detail for these functions, instead of adding yet another backward-incompatible algorithm? -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 15:49:57 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id B3D1937B401; Sun, 2 Feb 2003 15:49:56 -0800 (PST) Received: from heron.mail.pas.earthlink.net (heron.mail.pas.earthlink.net [207.217.120.189]) by mx1.FreeBSD.org (Postfix) with ESMTP id 4189F43F9B; Sun, 2 Feb 2003 15:49:56 -0800 (PST) (envelope-from tlambert2@mindspring.com) Received: from pool0402.cvx21-bradley.dialup.earthlink.net ([209.179.193.147] helo=mindspring.com) by heron.mail.pas.earthlink.net with asmtp (SSLv3:RC4-MD5:128) (Exim 3.33 #1) id 18fTrz-0006ul-00; Sun, 02 Feb 2003 15:49:51 -0800 Message-ID: <3E3DAE4D.3172D998@mindspring.com> Date: Sun, 02 Feb 2003 15:48:29 -0800 From: Terry Lambert X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Mark Murray Cc: "Andrey A.

They either, a) link to a static libc, and use its rand() always; or b) link to a shared libc, and use its rand(), as the binary API hasn't changed; or c) if they really need their own specific RNG, they include it themselves, and don't rely on libc at all.

The FreeBSD and SunOS man pages are very similar. The FreeBSD man page provides much more detail. Endianness may account for the difference.

Complaining about the ability to perform buffer overflows in code that is not SUID/SGID, thereby harming only yourself, is dumb. But... if you are going to keep gets/sprintf/strcpy/etc., just because you think you have to, even though you think they are dumb, then it's probably right to keep historical algorithms intact (technically, buffer overflows in gets() are only possible because the historical algorithm is being kept intact). > rand() and random() have a docimented interface, and empirical > programmer expectations about their outputs simply result in > bad code. Same for use of gets/sprintf/strcpy/etc. for Tuesday's definition of "bad code". I'd argue that providing threads results in bad code, too, but that doesn't mean that they're ging away any time soon. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 16:17:43 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id E485137B401 for ; Sun, 2 Feb 2003 16:17:41 -0800 (PST) Received: from devonshire.cnchost.com (devonshire.concentric.net [207.155.248.12]) by mx1.FreeBSD.org (Postfix) with ESMTP id 74E4D43E4A for ; Sun, 2 Feb 2003 16:17:41 -0800 (PST) (envelope-from bakul@bitblocks.com) Received: from bitblocks.com (adsl-209-204-185-216.sonic.net [209.204.185.216]) by devonshire.cnchost.com id TAA02092; Sun, 2 Feb 2003 19:17:32 -0500 (EST) [ConcentricHost SMTP Relay 1.15] Message-ID: <200302030017.TAA02092@devonshire.cnchost.com> Cc: Steve Kargl , Mark Murray , current@FreeBSD.ORG, "Andrey A.

FYI: The FreeBSD change was made in -r1.4 of random.c by Andrey in Oct 1996. The previous version of random.c behaves exactly the same as the one in 4.3BSD, SunOS and AIX. I am sorry I was too busy with other things then and missed this change. Andrey refers to an OCT 1988 CACM paper by Park & Miller "Random number generators: good ones are hard to find" as a justification for this change. Also FYI: NetBSD random(3) matches the 4.3BSD random(). Haven't checked OpenBSD.

The opinion of a random user: I run FreeBSD and not Linux because of the stability and predictability of the system. Changing a critical function like rand() when we know that there are applications which depend on its output does not seem like a good idea. A seperate function for those who need cryptographic randomness seems like a _much_ better idea. This is my person opinion.

Right there in the boot message, and again when you logged in, where the system indicated to you that it was a BSD system; the same notification that told you the resolved code is present in libc, the shared library implementation doesn't allocate specific chunks of UVM so the libraries can have their symbols resolved to fixed offsets instead of using PIC, that libc contains qsort(), etc.. Technically, it should be telling you that the SA_RESTART flag is present by default on signal handlers, too, so that you can more easily write a user space threads implementation using wrapper functions, and save a masking and unmasking system call for each potentially blocking call, but that's been broken for a long time, now, because of putative POSIX(SVID) compliance. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 16:23:49 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 647AE37B401; Sun, 2 Feb 2003 16:23:48 -0800 (PST) Received: from heron.mail.pas.earthlink.net (heron.mail.pas.earthlink.net [207.217.120.189]) by mx1.FreeBSD.org (Postfix) with ESMTP id 086FB43F3F; Sun, 2 Feb 2003 16:23:48 -0800 (PST) (envelope-from tlambert2@mindspring.com) Received: from pool0402.cvx21-bradley.dialup.earthlink.net ([209.179.193.147] helo=mindspring.com) by heron.mail.pas.earthlink.net with asmtp (SSLv3:RC4-MD5:128) (Exim 3.33 #1) id 18fUOo-00040z-00; Sun, 02 Feb 2003 16:23:46 -0800 Message-ID: <3E3DB63F.EA64E2D6@mindspring.com> Date: Sun, 02 Feb 2003 16:22:23 -0800 From: Terry Lambert X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Doug Barton Cc: Bakul Shah , current@FreeBSD.org Subject: Re: rand() is broken References: <200302022006.PAA25355@valiant.cnchost.com> <20030202131437.V79739@12-234-22-23.pyvrag.nggov.pbz> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-ELNK-Trace: b1a02af9316fbb217a47c185c03b154d40683398e744b8a436a0dc4695246dacda27198d12bbf8b1a7ce0e8f8d31aa3f350badd9bab72f9c350badd9bab72f9c Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Doug Barton wrote: > I can think of one significant benefit...

The correlation is still present with your patch and NSHUFF set to 10. For instance, try seeding rand() with contiguous monotonically increasing integers, and observe the four lowest-order bits. Just for the heck of it, I ran Marsaglia's tests on the rand() implementation in -CURRENT. The arc4random() implementation passed with flying colors as expected, whereas rand() seems to have some slight defects, particularly in the lowest and highest order bits. When I looked at rand()'s behavior with respect to different seeds, it failed miserably, both with and without your patch. The results are available at http://www.csua.berkeley.edu/~das/marsaglia/ I'm not necessarily advocating changing the algorithm at all, given that it's well known that many rand() implementations are not very random. But I also don't buy the argument that ``rand() should never ever change.'' If someone wants to do the work to improve the algorithm, that's fine with me.

Any software which always needs to get back maxint when it calls rand() is hopelessly broken :) Besides which, I don't recall advocating that change either. -Don To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 16:42: 9 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id A0C0C37B405 for ; Sun, 2 Feb 2003 16:42:08 -0800 (PST) Received: from a.smtp.serv.lythe.org.uk (pc4-oxfd1-6-cust225.oxfd.cable.ntl.com [62.254.141.225]) by mx1.FreeBSD.org (Postfix) with ESMTP id A702E43F43 for ; Sun, 2 Feb 2003 16:42:07 -0800 (PST) (envelope-from ejb@insolence.lythe.org.uk) Received: from insolence.lythe.org.uk (ejb@localhost [IPv6:::1]) by a.smtp.serv.lythe.org.uk (8.12.6/8.12.6) with ESMTP id h130g61a005917; Mon, 3 Feb 2003 00:42:06 GMT (envelope-from ejb@insolence.lythe.org.uk) Received: by insolence.lythe.org.uk (8.12.6/8.12.6/Submit) id h130g63r005916; Mon, 3 Feb 2003 00:42:06 GMT (envelope-from ejb) From: Edward Brocklesby To: Terry Lambert Subject: Re: rand() is broken Date: Mon, 3 Feb 2003 00:42:06 +0000 User-Agent: KMail/1.5 Cc: current@FreeBSD.ORG References: <200302022039.PAA13951@warspite.cnchost.com> <200302022117.49248.ejb@lythe.org.uk> <3E3DB5C4.56A04F70@mindspring.com> In-Reply-To: <3E3DB5C4.56A04F70@mindspring.com> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Content-Disposition: inline Message-Id: <200302030042.06444.ejb@lythe.org.uk> Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Monday 03 February 2003 12:20 am, Terry Lambert wrote: > Edward Brocklesby wrote: > > Where was it indicated that random() wouldn't change? > > Right there in the boot message, and again when you logged in, > where the system indicated to you that it was a BSD system; Sorry, I can't quite work out what you mean by this.

IMHO, it "shouldn't" break things (ie, things shouldn't be relying on it); but, well, I can accept there might be something that does.

I mentioned them because they are impossible to fix without hacking the system libc.so, whereas with source, you can recompile the code and override the libc version with your own. LD_PRELOAD could be used, if the interface is unchanged, and the saved state area is not managed promiscuously anywhere. The main problem is new code that depends on new behaviour conflicting with old code that depends on old behaviour. A number of the ASIC packages Bakul *may* be using come precompiled from the vendor, without source code (and yes, they have FreeBSD versions available, when you are slinging that kind of money around). > > I would say that depending on the internal algorithm used by rand() (or > > random()) is a bad idea; however, I don't know what the relevant standards > > say about this, so I won't say any further. > > > > (Why is it a bad idea?

Are you saying that it's > assumed random()'s API won't changed because it's guaranteed by BSD? Some behaviours are assumed to remain constant across BSD systems, which give the system it's "BSD flavor". For me, the random number generators have always been one of these. Personally, I'm concened about being able to repeat physics simulations that use drand48(), the code for the pair production coming from out of Berkeley, as well. So long as the algorithm doesn't change, the results obtained in 1982 are going to be repeatable at any point in the future. This is needed, if you intend to be able to build on published work that used a transformation of the raw numbers out of the simulation, and you need the same raw numbers, in order to do it. The experiment, in other words, needs to be repeatable. Basically, for simulations results like this, where the results are pair productions which are then kept or thrown away, based on whether the particular pair production is "possible", given the theorized physics, changing the random number generator is morally equivalent to changing the data from accelerator experiments, after the fact. Lucent just fired a PhD, very loudly and publically, for that type of number-fudging. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 17:13:44 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 0DCE137B401 for ; Sun, 2 Feb 2003 17:13:43 -0800 (PST) Received: from stork.mail.pas.earthlink.net (stork.mail.pas.earthlink.net [207.217.120.188]) by mx1.FreeBSD.org (Postfix) with ESMTP id 979E743F43 for ; Sun, 2 Feb 2003 17:13:42 -0800 (PST) (envelope-from tlambert2@mindspring.com) Received: from pool0402.cvx21-bradley.dialup.earthlink.net ([209.179.193.147] helo=mindspring.com) by stork.mail.pas.earthlink.net with asmtp (SSLv3:RC4-MD5:128) (Exim 3.33 #1) id 18fVAm-0005eS-00; Sun, 02 Feb 2003 17:13:21 -0800 Message-ID: <3E3DC1D2.C8EE85BB@mindspring.com> Date: Sun, 02 Feb 2003 17:11:46 -0800 From: Terry Lambert X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Steve Kargl Cc: Bakul Shah , Mark Murray , current@FreeBSD.ORG Subject: Re: rand() is broken References: <200302022106.h12L6naX051530@grimreaper.grondar.org> <200302022159.QAA13933@wellington.cnchost.com> <20030202223725.GA72744@troutmask.apl.washington.edu> <3E3DB9B3.A233B848@mindspring.com> <20030203004951.GA73497@troutmask.apl.washington.edu> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-ELNK-Trace: b1a02af9316fbb217a47c185c03b154d40683398e744b8a4144d44f298c0a9fc7162579d1753d88b666fa475841a1c7a350badd9bab72f9c350badd9bab72f9c Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Steve Kargl wrote: > On Sun, Feb 02, 2003 at 04:37:07PM -0800, Terry Lambert wrote: > > I can fire up my HP/UX and SunOS 4.1.3-U1 boxes too, if you need > > those, but I'm pretty sure the reason you got a different answer > > for newer Solaris was because it uses the SVR4 code, instead. > > That's the whole point!

No, the point is that *you* think I should not expect it, when historically, whether I *should* or not, I've been able to. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sun Feb 2 21:38:39 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 5E0BF37B401;

I'm experiencing a similar situation. I'm exporting /home and /usr with -alldirs and -maproot=0 on -current box. When I try to amd-mount /home from the -stable box, I can do it without any problem, but as for current:/usr, I need to give the IP address. Now, I could amd-mount (of course via NFS) these filesystems from the -current box, i.e. mounting local partitions via NFS using AMD, without this problem. I also tested if the number of filesystems being exported matters, but it doesn't seem to be. First, I swapped the order of the entries for /home and /usr in /etc/exports, and there was no difference. Then I commented-out /home entry, but after restarting mountd, I still couldn't amd-mount /usr from the -stable box. I'm still trying to figure out what's causing this, but so far, no luck.

I am running CURRENT cvsupped a few hours ago. This motherboard provides access to the BIOS via sio1. When booting, the serial BIOS shows everything that's happening until the point of booting the kernel (where it seems to switch video modes to have a bright white character set rather than the dull white/grey characters used initially). 1) Is there a way to prevent the FreeBSD kernel from ever switching into this different video mode, thus allowing me to continue to use the built-in serial terminal? The machine is a headless server, I don't care if video works as long as I can pull out a serial terminal. Furthermore, dmesg shows: -------- sio0: configured irq 4 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0 port 0x3f8-0x3ff irq 4 on acpi0 sio0: type 16550A sio1: configured irq 3 not in bitmap of probed irqs 0 sio1: port may not be enabled sio1 port 0x2f8-0x2ff irq 3 on acpi0 sio1: type 16550A -------- While Google shows several other users seeing same output, I have been unable to find a post that clearly explained what the cause of this "not in bitmap" error is. While sio1 is used by the serial BIOS and therefore reasonably could be expected to cause some error, sio0 should work just fine. 2) Even if the above errors are harmless, how do I make them go away?

I think you need to read the Serial Console section of the Handbook. You will find it here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html The reason that you lost the serial console after the kernel started is that you BIOS from that point is launched to the nearest galaxy's trashcan via hyperspace, I mean is not functional. You have to set up the serial console. ----------[ Free Software ISOs - http://www.fsn.hu/?f=download ]---------- Attila Nagy e-mail: Attila.Nagy@fsn.hu Free Software Network (FSN.HU) phone @work: +361 210 1415 (194) cell.: +3630 306 6758 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 1:54:51 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 34C4837B401 for ; Mon, 3 Feb 2003 01:54:50 -0800 (PST) Received: from gold.he.net (gold.he.net [216.218.149.2]) by mx1.FreeBSD.org (Postfix) with ESMTP id 9830343F79 for ; Mon, 3 Feb 2003 01:54:49 -0800 (PST) (envelope-from daver@gomerbud.com) Received: from tombstone.localnet.gomerbud.com (adsl-64-166-166-224.dsl.snlo01.pacbell.net [64.166.166.224]) by gold.he.net (8.8.6/8.8.2) with ESMTP id BAA14192 for ; Mon, 3 Feb 2003 01:54:47 -0800 Received: by tombstone.localnet.gomerbud.com (Postfix, from userid 1001) id 34F8F22D; Mon, 3 Feb 2003 01:54:45 -0800 (PST) Date: Mon, 3 Feb 2003 01:54:45 -0800 From: "David P.

Assuming that pam_krb5 is the module which is returning `24', I fixed that 4 days ago (Wed Jan 29 21:20:38 2003 UTC). Are you certain you have rebuilt pam_krb5? What is the output of `ident /usr/lib/pam_krb5.so' (should show revision 1.13 or later). The `four hours' does indeed correspond to DES's enabling of pam_krb5 by default in etc/pam.d/sshd.

You will - if you generate both sequences during the same program execution. There are no guarantees (and has never been) that srand()/rand() will give the same sequence after an OS update or on a different system or even between two different runs of the same program. > > This requirement would seem to indicate that changing > srand()/rand() isn't really possible... And, also, > I believe, why random() was introduced... a) srand()/rand() does use different algorithms on different systems so depending on some particular algorithm is inherently unportable. b) random() was not introduced because the sequence from rand() couldn't be changed. It was rather because the calling interface for srand()/rand() puts constraints on the implementation that result in rand() by necessity being a rather poor RNG. random() was introduced so one could have a RNG with better statistical properties. c) I believe the algorithm used by rand() *was* changed in -CURRENT about two years ago. (And pretty the same discussion ensued back then.) This change was done because the old algorithm used was particularly poor and it was possible to do better. Now some defect in the new algorithm has apparently been discovered which is why it needs to be modified again. > > Please, oh please, don't change that behavior in > srand()/rand(). > > - Dave Rivers - -- Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 5:14:57 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id D40F637B401; Mon, 3 Feb 2003 05:14:55 -0800 (PST) Received: from gold.he.net (gold.he.net [216.218.149.2]) by mx1.FreeBSD.org (Postfix) with ESMTP id 19D6143F75; Mon, 3 Feb 2003 05:14:55 -0800 (PST) (envelope-from daver@gomerbud.com) Received: from tombstone.localnet.gomerbud.com (adsl-64-166-166-224.dsl.snlo01.pacbell.net [64.166.166.224]) by gold.he.net (8.8.6/8.8.2) with ESMTP id FAA00929; Mon, 3 Feb 2003 05:14:47 -0800 Received: by tombstone.localnet.gomerbud.com (Postfix, from userid 1001) id F18D122D; Mon, 3 Feb 2003 05:14:46 -0800 (PST) Date: Mon, 3 Feb 2003 05:14:46 -0800 From: "David P.

One side says that rand() should always produce the same sequence for a given seed no matter what. This argument is bogus, because if you need exact reproducability across all platforms for all time, you should be using your own PRNG. The other side says that rand() should be a reasonably good RNG for most applications. It would be nice if things worked out that way, but there are enough broken rand() implementations out there that most people don't rely upon them. So I'd be inclined to call this argument bogus as well, except that I know someone who has been burned by a bad rand() while trying to test a randomized graph algorithm in C. My final thoughts are that having a better rand() implementation is a Good Thing, but it isn't that big a deal, and it certainly isn't worth all of this bickering.

Haven't seen it here, but I also don't have a configuration that looks like that one. In order to usefully debug this, we'll need some more information -- off the top of my head, it sounds a lot like a file system pseudo-deadlock of some sort. Perhaps a race to the root due to locking during a long operation. If you could compile your kernel with "options DDB", assuming it's not already, and set up a serial console, that would be helpful. When you reproduce the apparent hang, break into ddb on the console, and send the output of the following two commands: show lockedvnods ps You don't strictly have to use a serial console, but it sure is a lot easier to copy/paste the output than to copy by hand. You can find detailed instructions for setting this up in the Handbook and Developer's Handbook. A few things to tickle the thinking process: is the hang immediate, or does it wait until something else lists one of those directories? Does the hang occur if you perform the same behavior locally, or only over NFS? Do the disks churn during the deletion, or does it seem to be a CPU-intensive activity? Suppose you stick all these files a few levels fdown in the directory hierarchy -- does it help?

As for the colours etc, our machines have BIOS that do that too... I added a: set console=comconsole \ What's all this about then? It resets the console (to fix up the bios \ colour change), and outputs a banner. cr .( ^[c) to the start of /boot/loader.rc which is a vt100 reset code. This isn't a general purpose solution, but works for me.

I've seen this as well, FWIW. A previous employer had the same BIOS, and (mostly) refused to enable it in serial console mode, to "hide" the fact that their product was based on commodity PC hardware (they weren't fooling anyone but themselves). This is actually an escape sequence. I don't know why the BIOS stuffs out this, but the fix is to use Windows Telnet, which emulates a VT102, rather than FreeBSD Telnet in an xterm, which emulates an xterm. 8-(. > 1) Is there a way to prevent the FreeBSD kernel from ever witching into > this different video mode, thus allowing me to continue to use the > built-in serial terminal?

You can hack xterm to ignore "ESC" followed by anything followed by "m" (mode switch), and it will hide the problem. Normally, if there's no video card and no keyboard, FreeBSD will come up on the serial console, if you have set the console bit on the sio flags line in your kernel config. See "LINT" or "NOTES" for details, depending on which version you are using. > sio0: configured irq 4 not in bitmap of probed irqs 0 > sio0: port may not be enabled in the BIOS. > sio0 port 0x3f8-0x3ff irq 4 on acpi0 > sio0: type 16550A > sio1: configured irq 3 not in bitmap of probed irqs 0 > sio1: port may not be enabled in the BIOS. > sio1 port 0x2f8-0x2ff irq 3 on acpi0 > sio1: type 16550A > -------- > While Google shows several other users seeing same output, I have been > unable to find a post that clearly explained what the cause of this "not > in bitmap" error is. An explicit avoidance of resources which may be shared with MACH32 devices, which erroneosly leave some I/O ports enabled that should only be enabled if the chipset is in a particular mode. The result is that if you probe for a second or third serial port on machines with PALs that emulate the chipset, you get your video stomped. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 9:41: 6 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 4AC1937B401 for ; Mon, 3 Feb 2003 09:41:05 -0800 (PST) Received: from stork.mail.pas.earthlink.net (stork.mail.pas.earthlink.net [207.217.120.188]) by mx1.FreeBSD.org (Postfix) with ESMTP id E0EA543F9B for ; Mon, 3 Feb 2003 09:41:04 -0800 (PST) (envelope-from tlambert2@mindspring.com) Received: from pool0144.cvx21-bradley.dialup.earthlink.net ([209.179.192.144] helo=mindspring.com) by stork.mail.pas.earthlink.net with asmtp (SSLv3:RC4-MD5:128) (Exim 3.33 #1) id 18fkaa-00020A-00; Mon, 03 Feb 2003 09:41:01 -0800 Message-ID: <3E3EA95B.4CA321B0@mindspring.com> Date: Mon, 03 Feb 2003 09:39:39 -0800 From: Terry Lambert X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Attila Nagy Cc: Lucky Green , freebsd-current@FreeBSD.ORG Subject: Re: L440gx+ serial BIOS needs text mode References: <001301c2cb61$cbd70d90$6601a8c0@VAIO650> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-ELNK-Trace: b1a02af9316fbb217a47c185c03b154d40683398e744b8a4d4941a9956b4951e9403de3df62c0d90350badd9bab72f9c350badd9bab72f9c350badd9bab72f9c Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Attila Nagy wrote: > I think you need to read the Serial Console section of the Handbook. > You will find it here: > http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html This is actually no longer accurate.

Habibulin wrote: > Why not to use only credits for proc and make td_ucred macro like > td_proc->p_ucred? Or it has some meaning that i do not understand? td_ucred is a cached copy of p_ucred. The cached copy is potentially updated on any entry to the kernel. The reason for doing this is multi-fold: (1) Because of threading, access to p_ucred requires holding the process lock. Because we don't want to hold the process lock for every access control check, using a thread-access only reference avoids the lock. (2) Credential consistency. We perform the update check when we enter the kernel; if the comparison indicates they differ, we grab the process lock and update td_ucred. If they don't differ, we can continue. My understanding is that this is because a pointer comparison to determine if they are identical is permitted without a lock. It might be desirable to reason about the safety of this. This guarantees a single consistent "process credential" for each system call; that way there aren't races between separate access control checks resulting in inconsistent enforcement. So the end semantic is that there is, in effect, a single process credential. However, there may be divergence from that credential when threads are blocked in kernel and another thread changes the process credential, as the threads blocked in kernel won't pick up the new credential until they exit and re-enter the kernel. This approach, as I understand it, is taken by several other MP/threaded UNIXes. The strategy for selecting a credential to check against is generally to use td_ucred, and to hold no locks. You'll see that suser() does this, for example. Under some circumstances: specifically, credential updates, you need to hold the process lock and atomically check the process credential before updating. If the thread doesn't immediately leave the kernel (i.e., more checks might be performed), you'll also need to propagate the cred change to the thread from the process.

I guess it was pids before because pids are easier to correlate with processes in a ps(1) listing. It looks good to me though. The only thing I saw (minor nit) is that the assignment of LK_NOPROC to the lp->lockholder doesn't need a (struct thread *) cast because LK_NOPROC already has the cast in its definition. Other than that it looks ok to me. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 10:47:49 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 5660E37B405 for ; Mon, 3 Feb 2003 10:47:47 -0800 (PST) Received: from mail.speakeasy.net (mail16.speakeasy.net [216.254.0.216]) by mx1.FreeBSD.org (Postfix) with ESMTP id 442FA43FA7 for ; Mon, 3 Feb 2003 10:47:46 -0800 (PST) (envelope-from jhb@FreeBSD.org) Received: (qmail 23101 invoked from network); 3 Feb 2003 18:47:51 -0000 Received: from unknown (HELO server.baldwin.cx) ([216.27.160.63]) (envelope-sender ) by mail16.speakeasy.net (qmail-ldap-1.03) with DES-CBC3-SHA encrypted SMTP for ; 3 Feb 2003 18:47:51 -0000 Received: from laptop.baldwin.cx (gw1.twc.weather.com [216.133.140.1]) by server.baldwin.cx (8.12.6/8.12.6) with ESMTP id h13IlcUT085715; Mon, 3 Feb 2003 13:47:39 -0500 (EST) (envelope-from jhb@FreeBSD.org) Message-ID: X-Mailer: XFMail 1.5.2 on FreeBSD X-Priority: 3 (Normal) Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 8bit MIME-Version: 1.0 In-Reply-To: <200302011102.h11B25xk077482@spider.deepcore.dk> Date: Mon, 03 Feb 2003 13:47:46 -0500 (EST) From: John Baldwin To: Soeren Schmidt Subject: RE: Request for info from SiS chipset owners Cc: hackers@freebsd.org, current@freebsd.org Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On 01-Feb-2003 Soeren Schmidt wrote: > > I'm currently in the midst of an ATA chipset support mega rewrite/update, > and the last item on the list is SiS support. > > That where _you_ come into the picture, I need a pciconf -l from your > SiS based system! > > Just reply to this message with the output from pciconf -l and you > have helped me sort out the myriads of SiS chipsets out there.

The sense of the -P option was changed, and it makes it so you have to do extra work to get the console driver to do the right thing from inside FreeBSD proper, on a machine that could have its keyboard removed (or not). It's because the -h is implied, and it's a toggle. See also the last two sentences of the documentation for the "-D" option, as well. I guess the intent was to force someone to put in the effort in FreeBSD itself to make the "-D" option work in the kernel, as well as in the boot loader. Anyway, it was a particular problem with the SuperMicro motherboards with the AMI BIOS that's been the subject of the rest of this discussion (i.e. the ones that kick out the escape sequence at the end, for no good reason, except to screw up non-monochrome VTxxx emulators, and make it hard to use a UNIX box as the serial console). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 11:22: 8 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id D7BA337B401 for ; Mon, 3 Feb 2003 11:22:07 -0800 (PST) Received: from mail.sandvine.com (sandvine.com [199.243.201.138]) by mx1.FreeBSD.org (Postfix) with ESMTP id 37E5543FBD for ; Mon, 3 Feb 2003 11:22:07 -0800 (PST) (envelope-from don@sandvine.com) Received: by mail.sandvine.com with Internet Mail Service (5.5.2653.19) id ; Mon, 3 Feb 2003 14:22:00 -0500 Message-ID: From: Don Bowman To: 'Terry Lambert' , Attila Nagy Cc: Lucky Green , freebsd-current@FreeBSD.ORG Subject: RE: L440gx+ serial BIOS needs text mode Date: Mon, 3 Feb 2003 14:21:58 -0500 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain; charset="iso-8859-1" Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG > From: Terry Lambert [mailto:tlambert2@mindspring.com] ... > > Anyway, it was a particular problem with the SuperMicro motherboards > with the AMI BIOS that's been the subject of the rest of this > discussion (i.e. the ones that kick out the escape sequence at the > end, for no good reason, except to screw up non-monochrome VTxxx > emulators, and make it hard to use a UNIX box as the serial console). FYI, I've found that running under 'screen' fixes the problem with the odd escape sequences. One type of system we have puts out an escape sequence that is escape followed by 12 [.

Not sure what that is :) > The other works just great, except it switches to black on > black just as it switches to the OS :) I guess we don't get to escape from the gory details... 8-). The 12 ['s are compressed into a single [, for fully ANSI compliant state machines, because they are in the wrong column of the old DEC-published ASCII chart to terminate an escape sequence, so the real question is "what comes after the last [?". If you are seeing the 12 ['s, then your ANSI 3.64 state machine is not compliant. 8-). Back to the color change... The issue is support for the ISO ESC "[" "3" n "m" and the ISO ESC "[" "4" n "m" set foreground/set background color sequences. Windows Telnet doesn't support these, and neither does the terminal program that comes with Windows by default, but UNIX consoles do, and so does xterm, so running a dumb tty pipe like "tip" or "cu" on one of these passes them through. Running "screen" like you are, the emulation is a dumb VT100, and the escape sequences are interpreted by the "screen" program, instead of by the terminal window in which "screen" is running ("screen" is a terminal emulator that runs in a virtual terminal window, as an implementation detail for it being able to maintain multiple instances of display memory). The xterm didn't use to do this, by default, actually, and if you run your xterm with the "-cm -dc" options, or put: xterm.colorMode=false xterm.dynamicColors=false in your .Xdefaults file. I imagine this change is a result of some idiot wanting "colorls" to work by default, just as the BIOS spitting out the sequence was added at the request of some idiot to give people "one more reason not to use UNIX". 8-). If it really bothers you, you can disassemble, modify, reassemble, and then re-flash your BIOS to get rid of it (it bothered me, but not enough to do that, just enough to make me make an icon that started xterm with the color disabling arguments, which ran telnet to the terminal server connected to the serial consoles in the server room as it's "-e" argument). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 11:48:15 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 427E937B401; Mon, 3 Feb 2003 11:48:13 -0800 (PST) Received: from mail.tcoip.com.br (erato.tco.net.br [200.220.254.10]) by mx1.FreeBSD.org (Postfix) with ESMTP id 382DB43F75; Mon, 3 Feb 2003 11:48:11 -0800 (PST) (envelope-from dcs@tcoip.com.br) Received: from tcoip.com.br ([10.0.2.6]) by mail.tcoip.com.br (8.11.6/8.11.6) with ESMTP id h13Jlre27265; Mon, 3 Feb 2003 17:47:54 -0200 Message-ID: <3E3EC768.7030707@tcoip.com.br> Date: Mon, 03 Feb 2003 17:47:52 -0200 From: "Daniel C.

The scripts in /etc/rc.d ought to deal with setting up dhclient and whatever else correctly if the device is present (rc.conf settings not precluding this). I think, rather, that it is devd which should call rc.d to do things at device arrival, _after_ bootstrap has completed. -- Daniel C.

According to Doug's Intel page: http://people.freebsd.org/~dwhite/ipmi/setup_intel_scb2.html It's possible that it is, and that what's happening is some probe is writing to the port address on the I/O bus, causing the problem. If this is the case, then the only way to deal with it is to write a real driver for the thing (not the user space driver), and have the kernel claim it early, which would (should) keep other drivers from trying to poke it in the eye to see if their own hardware is there. It may also be that Intel has done the "Metolius" thing that Doug has indicated that they are pushing on his web page. If that's true, then the thing to do is to not load acpi.ko, and see if that fixes it for you. > As I read it on page 64 of > the manual (download from Intel), the second serial port is actually > connected through a multiplexer to the Baseboard Management Controller > (Dallas 82CH10) in my configuration. > ftp://download.intel.com/support/motherboards/server/l440gx/254151-003.p > df That's page 64 in the document, which is page 76 in the PDF reader, not page 64 in the PDF reader, which is the mechanical specification. 8-). > On page 36, the EMP 'always active mode' I selected suggests that > console redirection remains active, and the OS can not see the port (or > by extension take control of it). 5.3.5 #3 "suggests" the same thing, on page 64[76]. I guess the real question is whether or not ``the O/S cannot "see" the port'' is true or not. FreeBSD's serial port probing is, uh, "aggressive". It could have poked it and changed settings (e.g. from 19200, the EMP speed that the document wants to 9600, which FreeBSD wants, etc.). > Which would seem to leaves the graphics mode issue. FreeBSD should be > oblivious to the fact that this re-direction is even going on, but the > kernel seems to do /something/ that impacts the built-in serial console. Does it work in Linux? FreeBSD's console driver does flip the video mode, and that could be an issue, if the hardware operates on the basis of "screen scraping". There are a number of "serial console cards" that work by noticing differences in screen memory contents, and then dumping the necessary escape-sequenced byte-stream out to make a "VT100" screen contain the same contents in the same locations (quoted because console displays in PC's are 25 lines and a real VT100 is only 24 lines). If it's a screen scraper, then you should look at PCVT or some other alternate console driver, or you're not going to get what you want, as the thing loses it's marbles after the first video mode change. Or you could just interfere with the detection code in the current console driver. > I guess the idea is to not have to use the FreeBSD software serial > console, but use the hardware serial console out that comes with the > motherboard. Typical rack-mount use. That's what most of the screen-scraper cards try to do. FreeBSD by default isn't screen-scraper friendly. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 12:57: 4 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 58D3637B401 for ; Mon, 3 Feb 2003 12:57:02 -0800 (PST) Received: from milla.ask33.net (milla.ask33.net [217.197.166.60]) by mx1.FreeBSD.org (Postfix) with ESMTP id 09BBC43F79 for ; Mon, 3 Feb 2003 12:57:01 -0800 (PST) (envelope-from nick@milla.ask33.net) Received: by milla.ask33.net (Postfix, from userid 1001) id 3F3AB3ABB3B; Mon, 3 Feb 2003 21:59:13 +0100 (CET) Date: Mon, 3 Feb 2003 21:59:12 +0100 From: Pawel Jakub Dawidek To: freebsd-current@freebsd.org Subject: Re: LOR: if_ether.c -> route.c.

I just actually LOOKED at the patch and I have implemented it. (Of course, no kernel rebuild.) I still don't see anything. I am both doing the requested "echo" and writing a log entry. Neither shows up. Since it works, I now wonder if the problem is that the /var file system is not ready at the time. But why don't I see the output of the echo(1) commands? I do see that the device is detected before the config files are loaded or devd is started. After devd starts, I get the message from the entropy harvester and then the message that an attempt was made to load the driver that failed because the driver was already there.. This is followed by an LOR that I had previously reported. Then fsck starts. This is followed by network setup. I'm getting more confused by the minute. (And I have a multicast problem at Los Alamos that will tie me up for a while.) I still hate Mondays! R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.

All of them are more conventional than it might appear: - The 'screen scraper' for serial access to the BIOS works from software on the main (i386) CPU. The earlier machines didn't have on-board video, so mapped in some ordinary RAM to the video area if you ran them without a video card fitted; later machines have video hardware and the console redirection polls this RAM. Either way, it's BIOS software generating ANSI escapes out of the ordinary serial port, and this stops when the OS boots. - The management CPU sits between the external serial port connector and the UART in the main CPU's chipset. Hence the OS running on the main CPU always thinks it's got a standard COM port, it's just a question of whether data sent to/from that port makes it to the external connector or gets subverted by the management CPU. - On the latest machines featuring 'serial over LAN', you can persuade the management CPU to subvert the serial port and pass the data over one of the ethernet ports. This seems to use a proprietary protocol, but if you have one Windows machine somewhere with the Intel management software loaded on it, you can use that to proxy the protocol for any number of managed machines - ie. telnet to port 623 on the Windows machine, then connect back to the target machine and get attached to the serial console (and so get a FreeBSD login, if that's what is running on COM2). - Medium-aged machines seem to have all the hardware to subvert the serial and ethernet ports, but won't do serial redirection apart from controlling the BIOS. Upgrading the BMC software didn't help on the machine I had in this category. Disclaimer: the above is just from playing with the machines and reading the documentaton, so I may be wrong.

Note that this will add some pointer indirection to the scheduler calls, but it's pretty trivial. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 20:24:23 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id D942137B434 for ; Mon, 3 Feb 2003 20:24:18 -0800 (PST) Received: from colnta.issci.ca (mail.acns.ab.ca [142.179.151.95]) by mx1.FreeBSD.org (Postfix) with ESMTP id 7F0BD43F93 for ; Mon, 3 Feb 2003 20:24:17 -0800 (PST) (envelope-from davidc@colnta.issci.ca) Received: from colnta.issci.ca (localhost [127.0.0.1]) by colnta.issci.ca (8.12.6/8.12.6) with ESMTP id h144OBAM032294 for ; Mon, 3 Feb 2003 21:24:11 -0700 (MST) (envelope-from davidc@colnta.issci.ca) Received: (from davidc@localhost) by colnta.issci.ca (8.12.6/8.12.6/Submit) id h144OBM9032293 for current@freebsd.org; Mon, 3 Feb 2003 21:24:11 -0700 (MST) Date: Mon, 3 Feb 2003 21:24:10 -0700 From: Chad David To: current@freebsd.org Subject: minor yacc warnings Message-ID: <20030204042410.GA31903@colnta.acns.ab.ca> Mail-Followup-To: current@freebsd.org Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="y0ulUmNC+osPPQO6" Content-Disposition: inline User-Agent: Mutt/1.5.1i Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG --y0ulUmNC+osPPQO6 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline We are having minor problems with a newer gcc generating warnings for yacc due to yyrcsid not being used.

Rather than me showing you more semi-meaningful numbers from Marsaglia's tests, why don't you look at the following sequence, which I get by taking the lowest four bits of the 201st number in the rand() sequence for seeds of (0, 1, 2, ...). f c 9 6 2 f c 8 5 2 e b 8 4 1 e b 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e b 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 6 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 6 3 0 d 9 6 3 f Notice that 'f c 9' repeats in regular intervals and is always followed by a 5 or 6. There is a similar pattern for 'e a 7'. I think this pretty much demonstrates that the algorithm isn't good enough to generate high-quality randomness with respect to different seed values. I'm not suggesting that it absolutely must be replaced, since most rand() implementations aren't very good in the first place, but I'm pointing out that to do a good job of fixing it once and for all is harder than you might think. The program to generate this sequence follows. I ran this on a several-month-old -CURRENT system with the new generator, but without your latest patches. #include #include int main() { int i, j; for (i = 0; ; i++) { srand(i); for (j = 0; j < 200; j++) rand(); printf("%x ", rand() & 0x0f); if (i % 32 == 31) putchar('\n'); } } To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 21:49:15 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id A518B37B411 for ; Mon, 3 Feb 2003 21:49:06 -0800 (PST) Received: from ece.cmu.edu (ECE.CMU.EDU [128.2.136.200]) by mx1.FreeBSD.org (Postfix) with ESMTP id 4696A43F43 for ; Mon, 3 Feb 2003 21:49:06 -0800 (PST) (envelope-from allbery@ece.cmu.edu) Received: from [10.9.204.1] (allbery@dhcp-7-120.dsl.telerama.com [205.201.7.120]) (authenticated) by ece.cmu.edu (8.11.0/8.10.2) with ESMTP id h145msW23644; Tue, 4 Feb 2003 00:48:54 -0500 (EST) Subject: Re: comms/birda on -current and PalmPilot sync.

I don't have a -current system at present, and the test machine I was trying to build the other day (several missing packages with 5.0-RELEASE, sigh) doesn't have IR capability. If you run irs in the foreground (drop -Y, add -v 9) and attempt to hotsync, does irs report discovery of the Pilot? If not then you need to check that you're using the right serial port and that it is configured properly (don't use PnP autoconfiguration, and if possible set it as an SIR port in the BIOS). -- brandon s allbery [openafs/solaris/japh/freebsd] allbery@kf8nh.apk.net system administrator [linux/heimdal/too many hats] allbery@ece.cmu.edu electrical and computer engineering KF8NH carnegie mellon university [better check the oblivious first -ke6sls] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 22:30:53 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id EF25937B401 for ; Mon, 3 Feb 2003 22:30:50 -0800 (PST) Received: from magnesium.net (toxic.magnesium.net [207.154.84.15]) by mx1.FreeBSD.org (Postfix) with SMTP id 762ED43F93 for ; Mon, 3 Feb 2003 22:30:50 -0800 (PST) (envelope-from drbrain@magnesium.net) Received: (qmail 17115 invoked by uid 1100); 4 Feb 2003 06:30:50 -0000 Date: Mon, 3 Feb 2003 22:30:50 -0800 From: Eric Hodel To: David Schultz Cc: freebsd-current@freebsd.org Subject: Re: rand() is broken Message-ID: <20030204063049.GU46498@segment7.net> References: <20030202070644.GA9987@rot13.obsecurity.org> <20030202090422.GA59750@nagual.pp.ru> <20030203002639.GB44914@HAL9000.homeunix.com> <20030203100002.GA73386@nagual.pp.ru> <20030204054020.GA2447@HAL9000.homeunix.com> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="yIMHf/Pa6CzSkARF" Content-Disposition: inline In-Reply-To: <20030204054020.GA2447@HAL9000.homeunix.com> User-Agent: Mutt/1.4i Organization: Eric Conspiracy Secret Labs X-Eric-Conspiracy: There is no conspiracy Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG --yIMHf/Pa6CzSkARF Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable David Schultz (dschultz@uclink.Berkeley.EDU) wrote: > Rather than me showing you more semi-meaningful numbers from > Marsaglia's tests, why don't you look at the following sequence, > which I get by taking the lowest four bits of the 201st number in > the rand() sequence for seeds of (0, 1, 2, ...). >=20 f c 9 6 2 f c 8 5 2 e b 8 4 1 e b 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e b 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 6 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 1 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f c 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 7 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 6 3 0 d 9 6 3 f c 9 5 2 f b 8 5 2 e b 8 4 1 e a 7 4 0 d a 6 3 0 d 9 6 3 f=20 > Notice that 'f c 9' repeats in regular intervals and is always > followed by a 5 or 6.

I guess it's a bit more impressive when you select the right modulus. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Mon Feb 3 23:16:34 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 8CD0137B401 for ; Mon, 3 Feb 2003 23:16:32 -0800 (PST) Received: from franky.speednet.com.au (franky.speednet.com.au [203.57.65.5]) by mx1.FreeBSD.org (Postfix) with ESMTP id 6A89C43F75 for ; Mon, 3 Feb 2003 23:16:31 -0800 (PST) (envelope-from andyf@speednet.com.au) Received: from hewey.af.speednet.com.au (hewey.af.speednet.com.au [203.38.96.242]) by franky.speednet.com.au (8.12.6/8.12.6) with ESMTP id h147GO6e035011 for ; Tue, 4 Feb 2003 18:16:24 +1100 (EST) (envelope-from andyf@speednet.com.au) Received: from hewey.af.speednet.com.au (hewey.af.speednet.com.au [172.22.2.1]) by hewey.af.speednet.com.au (8.12.6/8.12.6) with ESMTP id h147GMnb051550 for ; Tue, 4 Feb 2003 17:16:23 +1000 (EST) (envelope-from andyf@speednet.com.au) Date: Tue, 4 Feb 2003 17:16:22 +1000 (EST) From: Andy Farkas X-X-Sender: andyf@hewey.af.speednet.com.au To: freebsd-current@FreeBSD.ORG Subject: sysinstall->Configure->Fdisk Message-ID: <20030204170512.R31941-100000@hewey.af.speednet.com.au> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG sysinstall's 'FDISK Partition Editor' won't let me create a second slice.

I boot up, log into root. I have two hard disks on the system. All of my mounted partitions are on ad0, except for one partition on ad2. I 'umount' that partition. I run the Disklabel Editor via sysinstall. I delete that partition, and then re-create it as a UFS2 partition. I do the 'w'rite, and everything looks fine. I drop out of sysinstall, do some things with that partition, and then decide to redo the above sequence.

Thank you for an expanation, I'll consider that. Now i'm trying to reanimate Thomas Moestls' capability work. Is anybody interested in such integration? I have almost bootable kernel and now will try to understand kernel structures locking and td_ucred/p_ucred interactions, to make nessesary changes. Or SEBSD make capabilities completly unnesessary?

If I understood correctly, the original post was indeed a misunderstanding about the console redirection of the BIOS, which is only effective until the kernel boots. From that point one must enable the serial console in kernel and I think this is what was omitted. Don't know. I remember that I had no special problems with my L440GX when last tried this, only the above one (enable serial console, which is trivial).

I don't try to make rand() good for high-quality pseudo-randomness, because it can be done by price of speed and, more important, big state size. Due to rand_r() restriction state size can be one word only, so we can choose rand() algorithm only from those which pass this restrictions. So, if you define USE_WEAK_SEEDING and re-compile rand.c, you'll get even worse results from your test. It means current variant is better then previous. If you know even better algorithm wich pass restrictions above, just tell and we consider switching to it. Returning to current algorithm, I am interested in good NSHUFF value in the range 100-2000.

As we can see, it even worse than current one.

You can do better than the present generator with 32 bits of state. See the following page by Neal Wagner (not to be confused with David Wagner): http://www.cs.utsa.edu/~wagner/laws/rng.html The section on LCGs suggests that the multiplier FreeBSD uses (7^5) is not particularly good, and points out some better values suggested by Knuth. I can't find the original discussion in TAOCP vol. 2, but I take N. Wagner's word that the numbers have been blessed by the holy hand of Knuth. I'm sure you can find more information if you search the literature. I apologize, but I don't have time to help you right now, and rand() isn't really a concern to me. > Returning to current algorithm, I am interested in good NSHUFF value in > the range 100-2000. Do you have any findings there? Well, if 0 doesn't work, and 10 doesn't work, and 100 doesn't work, then I'm not too hopeful about 2000. I appeal to Asimov's zero, one, infinity law.

We have tentative plans to support Capabilities-like models via a plug-in module using the MAC Framework sometime over the next few months. Slotting the POSIX.1e capabilities work into that makes a lot of sense.

The next bug is that there is % RAND_MAX + 1, not % RAND_MAX. The next is not the bug but portability thing alowing different RAND_MAX: you need to assign *ctx first and return it % RAND_MAX + 1 next, not assign *ctx % RAND_MAX + 1 like you currently does. -- Andrey A.

And the next bug is 32bit overflow there: tmp = *ctx * 62089911; must be tmp = (uint64_t) *ctx * 62089911; I'll produce working variant based on your patch... -- Andrey A.

All linear congruence generator have a fixed point. 0 is a far better fixed point than any other because it is more "obviously unsuited" (for some values of "obviously") as a seed value.

Changing RAND_MAX affects the algorithm in such a way that you should not do so without giving serious thought to revising the algorithm itself. In fact, RAND_MAX should be considered a characteristic of the algorithm rather than a parameter that regulates it. For that reason, and to make the algorithm more transparent to the reader, I've replaced RAND_MAX with 0x7fffffff in the attached patch. All that being said, adding 1 to *ctx before returning it (see patch) adresses both of your objections: a seed of 0 will not cause the LCG to get stuck, and the result of rand() will range between 0 and RAND_MAX inclusive. des@des ~/src% ./rndtest| head 2 0 1 7 1 7 f 2 5 3 f 6 a d 6 a 3 b 5 2 f 8 6 3 d 9 6 1 f 0 2 3 4 4 1 a f 3 b 5 4 2 a 6 f 0 0 6 9 5 1 7 c f 6 9 1 7 7 a 7 8 1 b 0 a c 7 a c 7 3 9 f 4 2 d 3 d 9 d 4 4 a 3 0 c f 7 6 2 5 9 2 3 7 5 b 7 7 f 9 9 b d 1 d c 5 2 b 6 7 c c 5 8 4 3 b 2 1 6 f 6 c 2 2 5 6 5 e a b b 8 e e 4 9 1 9 4 2 3 4 d b 3 5 3 a d 4 3 5 b 7 4 a c 1 2 4 e 5 d 9 0 6 6 8 b 7 f 8 8 2 6 1 c d 1 c f f 0 9 1 3 4 c 5 6 8 b 8 9 a 8 5 d b 8 8 d 7 e 7 0 c 2 c 8 0 6 5 8 f 8 9 6 0 c 9 d 4 7 0 8 5 2 c b 8 e 5 f 5 c d 1 c c b 3 8 8 f f 1 2 a 5 c f 0 5 f 2 4 e 9 0 1 1 9 2 5 f 0 0 2 2 d f b f 7 0 2 a 2 4 7 a 2 f 9 0 f 1 c 8 e 2 f c f 2 8 c d 5 7 0 f 2 b a 2 a 4 d 8 b c 4 0 4 DES -- Dag-Erling Smorgrav - des@ofug.org --=-=-= Content-Type: text/x-patch Content-Disposition: attachment; filename=rand.diff Index: lib/libc/stdlib/rand.c =================================================================== RCS file: /home/ncvs/src/lib/libc/stdlib/rand.c,v retrieving revision 1.11 diff -u -r1.11 rand.c --- lib/libc/stdlib/rand.c 2 Feb 2003 14:27:51 -0000 1.11 +++ lib/libc/stdlib/rand.c 4 Feb 2003 13:33:30 -0000 @@ -52,7 +52,7 @@ #endif /* TEST */ static int -do_rand(unsigned long *ctx) +do_rand(uint32_t *ctx) { #ifdef USE_WEAK_SEEDING /* @@ -63,21 +63,23 @@ return ((*ctx = *ctx * 1103515245 + 12345) % ((u_long)RAND_MAX + 1)); #else /* !USE_WEAK_SEEDING */ /* - * Compute x = (7^5 * x) mod (2^31 - 1) - * wihout overflowing 31 bits: - * (2^31 - 1) = 127773 * (7^5) + 2836 - * From "Random number generators: good ones are hard to find", - * Park and Miller, Communications of the ACM, vol. 31, no. 10, - * October 1988, p. 1195. + * New algorithm derived from + * The Laws of Cryptography: Pseudo-random Number Generation + * by Neal R.

Adding +1 you break algorithm formulae badly from math point of view, something else then given formulae not allowed here. You can change 'a' parameter to anything you want, but not add something at the end. -- Andrey A.

Yes we do. We get a better sequence for any given seed, i.e. we get less correlation between n and x(n) for any given x(0). I don't think it changes much for long sequences, but we get a better distribution for short sequences (including short subsequences of long sequences). As for patterns in the lower bits, we should try with a != 0 and see how that affects the results. I believe the purpose of a in the LCG algorithm is to scramble the lower bits.

Some are still uncommitted like the patch for gas(1) by Alexander Kabaev, and fixes to make disklabel(8) work for a different architecture (working with Poul-Henning on this one). There's still one issue to be resolved for "i386 on alpha" cross-releases: btxld(8) produces a binary image different from when it's run natively; I will look into this ASAP. (I had to take the produced by the Alpha box loader.bin from ${.OBJDIR} and pass it to btxld(8) on an i386 box, and then back to Alpha, to produce a working loader(8) (for kern.flp and "base" distribution). Alexander, please commit your patch for gas(1). It works! It was very kind of you to develop it, and it was done incredibly fast. Thanks a lot! Wilko, I still need an access to your ds10 Alpha for a few more days.

Well, I don't know for sure if XMMS uses rand/random, but I can tell you for sure that it's randomness _sucks_. It keeps playing the same songs from a Playlist again and again and again.

(By scratch install I mean I told it to delete and recreate all partitions except /users, so none of my old OS configurations should have been preseved.) When I installed 5.0 X11 worked. After turning off ACPI the built-in trackpoint mouse started working. I installed the XFConfig86 that was running on the portable from 4.7 and it came up without much trouble. However, after doing a cvsup, make buildkernel, make buildworld, mergemaster -v, installkernel and installworld, X no longer works. It seems to get a SIGABRT (signal 6) before it even paints the screen. Booting from kernel.generic (a complete copy of the initial kernel directory) and kernel.old does not fix it. Someone reported problems earlier and the suggested fix was to portupgrade -f wrapper. I tried this, but it did not help. I removed and reinstalled X from /stand/sysinstall (using FTP, not CD. Hmm.. maybe I should try pulling it from CD again?) and still have the same exit. I am attaching the output of dmesg, the XFree86 session log, my kernel configuration and the cvsupfile that I used. A couple things I have noticed that might or might not have bearing: dmesg shows realmem at 255MB when the box has over 700MB (top shows all of the memory, though) In dmesg, right after vga0 there are several unknown: lines The lock order reversal that is so popular in this list is showing up here. (It also shows up on the desktop system I'm using, but that box isn't running X.) apmd still isn't running (it stars then exits quietly) /dev/apm isn't being created (I'm sure this isn't relevant, but thought I'd mention it) probe complains about cardbus. I recall email about this topic earlier and expect it is irrelevant to the current problem. Any hints, tips, or pointers at documentation I've missed would be greatly appreciated. thanks, nomad ---------- dmesg Copyright (c) 1992-2003 The FreeBSD Project.

The summary is that when I compile the code as root, and then make it setuid (chmod u+s a.out) and then try to run it as a user, the tmpfile() fails. If I run it as root, it works fine. Conversely, I can give user ownership of the executable, and then run it as user, and it works great, but if fails for root. Again this is only with the setuid bit set.

Probably your real and effective UID's aren't the same.

Well, the code sample I submitted in my original email doesn't set any UID. It just creates a tmpfile() and then verifies that it succeeded. This is definitely a regression from 4.7 though.

We need to know how we think it's supposed to work, not how you think it's supposed to work to determine if the error is in the code OR in the fact some old bug was fixed going from 4.7->5.0, and the fix is biting you, OR it's a real bug. So if you don't want to answer the question about whether or not the UID root program sets the real UID from the effective UID, then you need to answer a different one: Are you saying that the code you posted, without calling the "setuid(geteuid());" worked on 4.7 and not on 5.0, when you "chown root, chmod 4755" it? -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Wed Feb 5 14:23:32 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 0B4C537B401 for ; Wed, 5 Feb 2003 14:23:31 -0800 (PST) Received: from critter.freebsd.dk (critter.freebsd.dk [212.242.86.163]) by mx1.FreeBSD.org (Postfix) with ESMTP id 5487B43FC1 for ; Wed, 5 Feb 2003 14:23:27 -0800 (PST) (envelope-from phk@freebsd.org) Received: from critter.freebsd.dk (localhost [127.0.0.1]) by critter.freebsd.dk (8.12.6/8.12.6) with ESMTP id h15MNQYu046273; Wed, 5 Feb 2003 23:23:26 +0100 (CET) (envelope-from phk@freebsd.org) To: "Andrey A.

The problem is the clock jump, not DEVFS.

For anyone who cares: Additional information was provided off-list. The problem was indeed that "setuid(geteuid());" was missing from the program. Apparently, there was a bug fixed in 4.7 -> 5.0, where the effective UID was being tested instead of the real UID.

Clock jump happens as it supposed when adjkerntz(8) corrects machine clock back to GMT via various CPU_* sysctl's. Could touched DEVFS stamps be fixed back to something useful in the same sysctl code too? -- Andrey A.

Really? I just took a quick look at this, but I have to shove off for now. In initial tests, I get the different results depending on whether I'm using static or dynamic linking. But maybe it's me, I'll look more carefully later. How about pointing out the bug you found? Cheers, -- Jacques A. Vidrine http://www.celabo.org/ NTT/Verio SME . FreeBSD UNIX .

The "bug" was that my test program seperated the operation into a function so I could try different crap, and adding the setuid(geteuid()) put a zero on the stack in the stack position Mike discovered was being used uninitialized.

This should be well known to devfs users. devfs sets at least some of the times before adjkerntz can run, and nothing fixes them, so these times are wrong by the timezone difference. The problem is more obvious East of Europe since the timezone difference is positive and large. The bug has less noticable effects West of Greenwich since the difference is negative so the wrong timestamps are in the past. For me the difference is +10 or +11 hours so there is a 10 or 11 hour window after booting in which `ls -l /dev' and some periodic scripts report strangeness. There are related problems for boottime. These are hacked around in tc_setclock() by adjusting boottime when the time is changed. This works right when the time is changed soon after booting by adjkerntz or ntpdate but wrong after that.

Think diskless NFS, think MD(4) based root, think... The only problem is that we set the kernel time wrong from the RTC. We should stop doing that, rather than invent bandaids and hacks to restore the damage it does. I avoid it entirely by using UTC time in my RTC, but this is not an option for machines which have to boot broken-as-designed OSs. The most practical way to do it right would be to have adjkerntz update a file under /boot/ ("/boot/timezone.hint") which the loader reads in and passes to the kernel, so that the kernel can set the time right from the RTC based on that. This doesn't work well for machines which are turned off for long periods of time unless the file contains predicted DST transitions for the next year or so. The most correct solution would be for the loader (preferably) or the kernel to know about timezones, including DST, so that it would also work correct for a machine which has been powered off for half a year. (I'd prefer the loader because we don't need this code once userland can take over.) I don't know if modern bios's know about timezones and DST, I've seen some that has setup functions for it, but I don't know if there is any way to find the information they store and I don't think such features are widespread.

More precisely: some are mounted, but they are mounted read-only (modulo the bug that adjkerntz is run a little after mounting filesystems read-write).

Ok, I did some extensive tests overnight. Essentially I still had `fwcontorl -g 20` and SBP_QUEUE_LEN=1 and maxopenings=1 and `debug.sbp_debug=1`. hw.firewire.sbp.max_speed started at 0 and got 2 at the end. After treating two `iozone -s 51200m -r1024k` on the platters overnight without problems I started with a plain sbp.c and no `fwcontorl -g 20`. I get constant rates of 13MB/s on each disk. No problems so far. Seems you got it. Thanks! BTW: switching on debug.firewire_debug gives zillions of 'kick'... Is this just a notification about the code-path?

After the last general elections in my country where the incumbent president MR. Robert Mugabe won the presidential election, the government has adopted a very aggressive land reforms programme. This programme is solely aimed at taking the land owned by white African farmers for redistribution to black Africans. This programme has attracted worldwide condemnation from world leaders including British prime minister,MR Tony Blair and also forced several white farmers to flee the country for fear of victimization and physical abuse. Few months ago, our headquartes in Harare was attacked and looted by black protesters and in the process burnt down the whole building. Fortunately,they did not get access to the documents of our union funds which belong to the co- operation. This cash is kept in UBS PRIVATE BANK IN SWITZERLAND.We are worried that the money is no longer safe because our president ,ROBERT MUGABE might freeze the account if he gets to know about it. Now I have the funds deposit documents in my hands Once I can get your commitment and sincerity of investing this funds on our behalf then I would proceed to get the funds transfered into your nominated bank account anywhere in the world.You do not have anything to worry about as I would undertake all charges i have already perfected all avenues to get the money into your account. i have the mandate from Mr Max Crawford,the president of the union to get the funds out as fast as possible.You would be compensated for all your effort once we have gotten the funds to your account. Please get back to me if you can be of assistance and I would want our correspondence to be via email as most phone lines of white farmers are bugged by the government. I expect your confidentiality and your promptresponse to this mail so as to proceed. dudley rogers ------------------------------------------------- HKNETMAIL.COM Free WEB MAIL Service by HKNET To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Thu Feb 6 5:11:52 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 8E3B537B401 for ; Thu, 6 Feb 2003 05:11:51 -0800 (PST) Received: from MX1.estpak.ee (ld1.estpak.ee [194.126.101.98]) by mx1.FreeBSD.org (Postfix) with ESMTP id 297DC43F93 for ; Thu, 6 Feb 2003 05:11:50 -0800 (PST) (envelope-from kalts@estpak.ee) Received: from kevad.internal (80-235-38-93-dsl.mus.estpak.ee [80.235.38.93]) by MX1.estpak.ee (Postfix) with ESMTP id C3BBE8880E; Thu, 6 Feb 2003 15:10:28 +0200 (EET) Received: from kevad.internal (localhost [127.0.0.1]) by kevad.internal (8.12.6/8.12.6) with ESMTP id h16DBeQO003126; Thu, 6 Feb 2003 15:11:40 +0200 (EET) (envelope-from vallo@kevad.internal) Received: (from vallo@localhost) by kevad.internal (8.12.6/8.12.6/Submit) id h16DBdJV003125; Thu, 6 Feb 2003 15:11:39 +0200 (EET) (envelope-from vallo) Date: Thu, 6 Feb 2003 15:11:39 +0200 From: Vallo Kallaste To: Kris Kennaway Cc: freebsd-current@freebsd.org Subject: Re: tired of crashes Message-ID: <20030206131139.GA3063@kevad.internal> Reply-To: kalts@estpak.ee References: <20030205094744.GA949@myhakas.internal> <20030205184009.GD11124@rot13.obsecurity.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20030205184009.GD11124@rot13.obsecurity.org> User-Agent: Mutt/1.5.1i-ja.1 Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Wed, Feb 05, 2003 at 10:40:09AM -0800, Kris Kennaway wrote: > > --- > > panic: ufs_dirbad: bad dir > > cpuid = 1; lapic.id = 01000000 > > boot() called on cpu#1 > > I get those on the bento cluster when the disk is starting to fail. > dd'ing /dev/zero over it usually gives it some more life by forcing it > to remap bad blocks as it goes. The disk has been in use for ~1 year and both primary and grown defect lists are the same as in the beginning. So far haven't observed any signs of dying disk. Also no other disk activity has been problematic, I have several times copied over the disk contents (~5GB) to other disk to re-newfs the filesystem. -- Vallo Kallaste kalts@estpak.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Thu Feb 6 5:17:30 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 2603237B406; Thu, 6 Feb 2003 05:17:29 -0800 (PST) Received: from yoda.warpnet.ro (yoda.warpnet.ro [217.156.25.2]) by mx1.FreeBSD.org (Postfix) with ESMTP id 36E7A43FAF; Thu, 6 Feb 2003 05:17:26 -0800 (PST) (envelope-from ady@freebsd.ady.ro) Received: from yoda.warpnet.ro (localhost [127.0.0.1]) by yoda.warpnet.ro (8.12.6/8.12.6) with ESMTP id h16DHGXT068792; Thu, 6 Feb 2003 15:17:16 +0200 (EET) (envelope-from ady@freebsd.ady.ro) Received: from localhost (ady@localhost) by yoda.warpnet.ro (8.12.6/8.12.6/Submit) with ESMTP id h16DHFGI068789; Thu, 6 Feb 2003 15:17:16 +0200 (EET) (envelope-from ady@freebsd.ady.ro) X-Authentication-Warning: yoda.warpnet.ro: ady owned process doing -bs Date: Thu, 6 Feb 2003 15:17:15 +0200 (EET) From: Adrian Penisoara X-X-Sender: ady@yoda.warpnet.ro To: freebsd-current@freebsd.org Cc: freebsd-hackers@freebsd.org Subject: New technologies in FreeBSD 5.x vs. 4.x Message-ID: <20030206151052.U68316@yoda.warpnet.ro> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII X-RAVMilter-Version: 8.4.2(snapshot 20021212) (yoda.warpnet.ro) Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi, I'm about to write an article on FreeBSD for PC Magazine Romania and I would like to concentrate on the new technologies introduced in FreeBSD 5.x.

Greetings Adrian, The most significant new features are listed in the Release Announcement[0]. There is greater detail available in the Release Notes under "What's New"[1]. > I would also like, if possible, to get in touch with a few of the main > developers that took charge of coding them. You can contact the person listed as MAINTAINER in the Makefile for the part of the source tree you are concerned with. If there is no MAINTAINER listed, a quick trip through CVSWeb[2] will reveal who has been the most active committer to that section of the tree. I would, of course, recommend courtesy and patience when approaching FreeBSD develoeprs for an interview. Most of them are quite busy.

I recently upgraded my machine from 4.7-stable to 5.0-release. The upgrade went almost smoothly. I say almost because so many things changed between 4.x and -current that I missed a few. :) But overall, I'm quite happy with the results. I had problems with almost all my apps, at first. Third part applications that weren't recompiled during the buildworld (ports) had linking problems. Take wget, for example: anarcat@lenny[~]% wget /usr/libexec/ld-elf.so.1: /usr/local/lib/libintl.so.4: Undefined symbol "st= pcpy" anarcat@lenny[~]%=20 Recopmiling wget solves the problem. Some folks pointed out to me this might be due to the fact I forgot to include COMPAT4X=3Dyes in my make.conf. At first I had considered upgrading from -release to -current (because I'm a careless freak), so I already had my /usr/src cvsup'd to yesterday's current. So I builded world over that and installed it. Of course, that didn't solve the linking problem. But it made another problem appear. My dear user-friendly xmms now fails to start. This machine is used by the whole family here and I got really embarrassed over this. :) xmms seemed to pop an empty window, and sucked all the CPU time available on my AMD Druon 1GHz: CPU states: 14.4% user, 0.0% nice, 84.4% system, 1.2% interrupt, 0.0% id= le Mem: 116M Active, 56M Inact, 92M Wired, 600K Cache, 92M Buf, 862M Free Swap: 498M Total, 1452K Used, 496M Free =2E.. 891 anarcat 115 0 15820K 7060K RUN 0:05 82.69% 18.31% xmms =2E.. So I told my self, "eh, that's -current for you!" ;) And I thought that -release wasn't so bad after all and that the upgrade didn't give me anything good anyways. So I downgraded to -release. Without success. xmms hangs as before. But it used to work on -release!!! How is that possible? Using SIGINFO, I've witnessed the following: load: 1.12 cmd: xmms 9744 [*Giant] 0.33u 0.85s 1% 7144k load: 1.19 cmd: xmms 9744 [*Giant] 0.41u 1.06s 1% 7144k load: 1.19 cmd: xmms 9744 [running] 0.41u 1.09s 1% 7144k load: 1.19 cmd: xmms 9744 [*Giant] 0.41u 1.12s 1% 7144k load: 1.19 cmd: xmms 9744 [running] 0.41u 1.14s 1% 7144k But I'm able to see this only when it system is loaded (with the compilation of a port, for example). So I suspect xmms is somehow looping over the giant lock, for some reason. truss gives me the following: sigprocmask(0x3,0x28144710,0x0) =3D 0 (0x0) SIGNAL 27 SIGNAL 27 gettimeofday(0x281678b8,0x0) =3D 0 (0x0) sigprocmask(0x3,0x28167924,0x0) =3D 0 (0x0) sigreturn(0xbfbff4a0) =3D 0 (0x0) sigreturn(0xbfbff330) =3D 135891072 (0x8198880) sigreturn(0xbfbff330) =3D 135891072 (0x8198880) sigreturn(0xbfbff330) =3D 135891072 (0x8198880) And ktrace: 26035 xmms CALL mmap(0,0x4788,0x3,0x1000,0xffffffff,0,0,0) 26035 xmms RET mmap 686489600/0x28eb0000 26035 xmms CALL munmap(0x28eb0000,0x4788) 26035 xmms RET munmap 0 26035 xmms CALL mprotect(0x28e3c000,0x62000,0x5) 26035 xmms RET mprotect 0 26035 xmms CALL sigprocmask(0x3,0x28144710,0) 26035 xmms RET sigprocmask 0 26035 xmms PSIG SIGPROF caught handler=3D0x28159510 mask=3D0x0 code= =3D0x0 26035 xmms CALL gettimeofday(0x281678b8,0) 26035 xmms RET gettimeofday 0 26035 xmms CALL sigprocmask(0x3,0x28167924,0) 26035 xmms RET sigprocmask 0 26035 xmms CALL sigreturn(0xbfbff4a0) 26035 xmms RET sigreturn JUSTRETURN 26035 xmms PSIG SIGSEGV caught handler=3D0x28159510 mask=3D0x0 code= =3D0xc 26035 xmms CALL sigreturn(0xbfbff330) 26035 xmms RET sigreturn JUSTRETURN 26035 xmms PSIG SIGSEGV caught handler=3D0x28159510 mask=3D0x0 code= =3D0xc I include my dmesg at the end of this mail, in the meantime, here are the pcm sysctls that might be relevant: root@lenny[/usr/home/anarcat]# sysctl hw.snd = =20 hw.snd.targetirqrate: 32 hw.snd.report_soft_formats: 1 hw.snd.verbose: 1 hw.snd.unit: 0 hw.snd.maxautovchans: 2 hw.snd.pcm0.buffersize: 4096 hw.snd.pcm0.vchans: 1 I also tried: root@lenny[/usr/home/anarcat]# sysctl hw.snd =20 hw.snd.targetirqrate: 32 hw.snd.report_soft_formats: 1 hw.snd.verbose: 1 hw.snd.unit: 0 hw.snd.maxautovchans: 0 hw.snd.pcm0.buffersize: 4096 hw.snd.pcm0.vchans: 0 I had odd crashes with xmms before, but *crashes*, no hangs. :) I am available for testing and debugging, and I am eager to solve this problem, since xmms is a must here, right now.

That'd be nice if the L440GX+ was IPMI compliant. It isn't. :-) You're better off trying to use the intpm driver to talk to the old-style monitoring chips. Several IPMI features came from features implemented on the BMC on the L440GX, but it still uses the proprietary smbus interface. I never fiddled with the BMC features of the L440GX board. Linux's monitoring driver does talk to it though, you might be able to port it over. On the current generation Intel boards, serial redirection is handled by the BIOS. Once the kernel starts and the kernel takes over output, that redirection ceases to function. By that point, though, you have the usual FreeBSD serial console facilities and thus have a smooth transition. I suspect the same applies for any other Intel motherboard that supports serial redirection. You can confirm support for serial redirection by downloading the Technical Product Specifications for the Intel board you're interested in through support.intel.com. We have Tyan boards at my current employer with serial redirection and they work the same way. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Thu Feb 6 13: 3:40 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 1E19737B401 for ; Thu, 6 Feb 2003 13:03:39 -0800 (PST) Received: from carver.gumbysoft.com (carver.gumbysoft.com [66.220.23.50]) by mx1.FreeBSD.org (Postfix) with ESMTP id ABA5F43F3F for ; Thu, 6 Feb 2003 13:03:38 -0800 (PST) (envelope-from dwhite@gumbysoft.com) Received: by carver.gumbysoft.com (Postfix, from userid 1000) id 98F7E72E7B; Thu, 6 Feb 2003 13:03:38 -0800 (PST) Received: from localhost (localhost [127.0.0.1]) by carver.gumbysoft.com (Postfix) with ESMTP id 97C0972E7A; Thu, 6 Feb 2003 13:03:38 -0800 (PST) Date: Thu, 6 Feb 2003 13:03:38 -0800 (PST) From: Doug White To: Andrew Gordon Cc: Lucky Green , Subject: RE: L440gx+ serial BIOS needs text mode In-Reply-To: <20030204000002.P42367-100000@server.arg.sj.co.uk> Message-ID: <20030206130208.A60537-100000@carver.gumbysoft.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Tue, 4 Feb 2003, Andrew Gordon wrote: > - On the latest machines featuring 'serial over LAN', you can > persuade the management CPU to subvert the serial port and > pass the data over one of the ethernet ports.

This is what the second ISO image is for. It contains the holographic shell and is sometimes called the "fixit" disk. Boot it select Fixit. Then follow the instructions. Or, if you just want to partition, use the "Configure" option and select Fdisk. (For this, you don't even need the Fixit disk. The main OS disk can do this.) R.

Odd. Any idea if it still > occurs with a more recently built kernel? I've felt like I tried everything so far, and I cannot figure out what the problem is, I've done numerous hardware tests, and every single one was passed with flying colours. I have narrowed it down to apache locking the box though. So I'm not sure what I can do to fix this, because it is very tedious to have to keep manually rebooting the box everytime it locks (sometimes 3 times a day!) Can anyone please suggest something to fix this issue? If any of the developers read this, I can give you ssh to the box if required so you can see what's happening.

Also, this may not be specific to -current, I think I saw it on -STABLE as well a while ago.

I have about six boxes at work using 5.0-CURRENT and 5.0-RELEASE with NIS accounts without any apparent problems. I did shoot my toes several times during the upgrade process, though. I think I ended up manually forcing rpcbind to be on as well as nisclient. If finger and so on are working, I'm not sure why you'd see this failure, though. Does "id username" return the correct grouplist? Does this machine have multiple network interfaces, or just one?

I disable yp by simply hitting "domainname ''", and re-enable it by hitting "domainname mynisdomainname". The application mentioned above is winconnect (http://www.thinsoftinc.com/products_winconnect_info.html), a RDP 5.1 capable client for Linux. I think the yp ability inside linux emulator is somewhat broken.

    1. CD Review - Jazzhole: 'Circle Of the Sun'      

    JazzholeHow many of yall remember the NYC based group called " JAZZHOLE"? Remember they were pretty hot for a while in the 1990's 'acid jazz' scene, putting out some truly innovative and FUNKY sounds.  Jazzhole have been members of Soul-Patrol for several years now and I am pretty excited to be able to be in a position to tell you all about their SLAMMIN new CD called 'Circle Of the Sun. I've been listening to it over the past few weeks and it's badd! 

    Jazzhole has been around for quite a while and has been one of the leaders in putting out some high quality (and FUNKY) music against the current tide of worthless CRAP for the last decade.

    Of course the rest of the world now seems to be catching up with the vision of what Jazzhole has been trying to do. I think the mass media now refers to this kind of music as "neo soul"? (screw the label, the music is damn good) However they aren't ready to rest on the accomplishments of the past. Jazzhole has got a BRAND NEW CD called "Circle Of the Sun", which is off the hook and well worth your consideration at this time. Go to the link and check it out and while you are there you can also check out some of the sound clips from the legacy that Jazzhole has been building over the course of the past 10 years. take a listen and let me know what cha think?

    (PREDICTION: 2003 will be a GREAT year for NEW music)

    --Bob Davis

    2. Floetry's "Floetic" (Hype or the Real Deal?)

    What kinda hype? If there's any hype surrounding Floetry's "Floetic", I haven't been paying much (if any) attention to it. And, if the "hype" YOU mention comes from, say, airings of music videos on cable, then forget it, since I don't DO cable, man... "Floetic" came to my attention, via word-of-mouth from some other, independent sources whom I trust. But, as always, and in the end, I form my OWN opinions about the music I like, as well as other things in this life. *I* am MY OWN leader (within), with the Lord (Goddess) as CEO (outside of myself)... That's just how it goes, for me. Moving on... What's my opinion? I like this CD, overall :)... As I listen to a lot of the cuts, I find myself wantin' to dance! There IS a groove there that *I* (at least) can feel. Plus, I have been gettin' into the lyrics, as well as the interplay between the spoken word and singing on many of the selections. AND, I don't get offended and/or depressed by the lyrics, either (a BIG thumbs UP!...). IMHO, these sisters have got somethin' goin' on, have a few thangs to say, and *I*, at least, feel it, and see more potential. As far as I can tell, the "floetist" can FLOW, and the "songstress" can SANG, in this duo. "Floetic" (title cut), "Fun", "If I Was A Bird", and "Butterflies" are some of my favorites on that CD, and at the moment. And, I'm sure that you know that Floetry wrote "Butterflies", and Michael Jackson recorded it on his OWN joint, right? Well, *I* like Floetry's version of THEIR own song much better :)... So, that's my opinion. Remember, YOU asked for it, and you GOT it...LOL! What say YOU??

    3. Commentary: I have a few issues with Tom Joyner (part 1)      

    a. When he comes into a market he forces the stations established morning man OUT! He even did it to his own 'boy' Isaac Hayes.
    Tom is going to be the only star and he is not going to deal with another DJ who has a style or following.

    b. I also am disheartened at the number of black author's who have written to talk about the shaft of being on Sybil's book club. They pay $1500.00 for the 3 minutes on air. They get there and find out Sybil has not read their book so they must supply notes and then there is no promotion for the event and the author's (unless they are already big names) have no audience for the book club portion.

    c. Also, I heard a few years ago there was a story explaining that when you call into the TJ Foundation to donate, $15.00 to HBCU that $7.00 goes to the school and $8.00 goes to the TJ foundation. I'd love to really find out the truth behind that one if anyone can shed some light? The scholarship money TJ passes out over the air is sad. $1500.00. The cabins on his cruise cost more. Go to a local Links, Jack & Jill, Delta, Omega, Alpha, AKA any of their scholarship dinners and they'll be giving out far greater amount than TJ does on a national level. For the money TJ pulls in he should be giving substantial awards.

    d. He says his mission is supposed to be keeping old school on the Air. Well, commercial artists with big labels don't need his help but why they are his guests? Look at his guest list. Do you ever see the DELLS? Do you ever hear Ray, Goodman & Brown? What about Billy Paul and TJ always has a Mrs. Jones story. Look at the core of Classic Soul and the artists AREN’T on Tom's show. If you can't buy your way on it isn’t happening. How many times does Luther need to be a guest? But Edwin Starr, Bettye LaVette, King Floyd, and a list of Classic Soul artist all had new CD's released but you won't hear them on TJ's show. Ever hear TJ talk about the inductions into the R&R Hall of Fame. He has a national platform and could champion a few black artists into the hall. But the voice of Black America is silent on those issues. I just think if he is going to wear that title he should truly use his voice where it will best benefit his listener’s IMHO

    4. Concert Review: Victor Wooten at the Knitting Factory 1/21/2003  


    Victor Wooten

    We had an absolutely MAGNIFICENT time at the Victor Wooten Show last Friday here at the Knitting Factory Hollywood...Victor, his brothers and MC Divinity were a musician's delight and certainly the standing room only capacity crowd of approximately 600 thought so as well during the 3 1/2 hour performance which should ensure many more return performances in the future!! Oh Yes!!

    AWESOME to say the least and this performance truly put all the pieces in place as we of course saw him with Bela at UCLA several months ago and now we have had the wonderful opportunity to see the extensions of this Great Showman, and the complete band, down to the magic tricks. In between time, we were treated to a fabulous segment with J.D. Blair who sat in on the drums and came to the forefront demonstrating one of the routines he and Victor used to do when he was in the group prior to his current duties with Shania Twain (who Victor also told the audience to look out for JD at the Super Bowl performance). Reggie Wooten is no doubt "The Teacher" and his precision is lighting sharp and colorful. You can tell they had a BLAST coming up together playing real music with the correct chord changes...Most of the material was from the ‘Live In America’ CD with stratospheric Funk, Fusion, Soul and Jazz with plenty of comic relief in between..:-)

    The show was simply FANTASTIC and Victor's final note on the war, peace and simply just pulling together as one people, with LOVE, completed the Pure, Live, music excursion...They are at The Coachouse this week in San Juan Capistrano.. again we look forward to their return.. And as Debra, Karl, Bob, Gary and all have said time and time again after seeing their show, the Wooten Brothers should be A MUST for all to see!!

    Lastly, it was pleasure to meet and greet the new Los Angeles/West Coast Soul-Patrol Coordinator Vernon Wright  who we look forward to working with in the next couple of months as we emerge from our studio projects...:-)

    It's All About the Music..:-)

    5. Competition in Radio and Concert Industries Act: Good News For Artists and Consumers (Bad News For Clear Channel, Joyner, Hughes and other KNEE-GRO Radio Station Operators)  

    I urge you all to please see the details about this legislation at Senator Feingold's website at:
    http://feingold.senate.gov/~feingold/releases/03/01/2003128910.html

    In my opinion this is a good piece of legislation and hopefully it will be ratified by
    Congress.
    I know that Black folks aren't supposed to care about stuff like this, but it's when we don't that we usually end up getting SCREWED.
    If it this legislation is passed, there will be relief provided to BOTH artists and consumers.
    It would ultimately lead to an END to the current MONOPOLISTIC/FASCIST policies currently being employed by KNEE-GRO RADIO STATION OPERATORS (both Black and White).

    In my opinion this is an important development and it's RIGHT ON TIME FOR BLACK HISTORY MONTH. My view is that our 'history of our music won't even have a future at all', if the CESSPOOL of modern day KNEE-GRO radio isn't cleaned up.

    I would ask ALL Soul-Patrollers to consider doing one or both of the following...

    a. If you feel so inclined, feel free to write Senator Feingold at the following email address to tell him that you support this legislation:
    russell_feingold@feingold.senate.gov

    b. Forward this email to as many people as you know who care about the past present and
    future of OUR culture.

    I urge you all to please see the details about this legislation at Senator Feingold's website at:
    http://feingold.senate.gov/~feingold/releases/03/01/2003128910.html

Our current favorite card is the intel i82559-based fxp cards. They handle the load best on our testing of 100M cards. Remember that our load is large and small packets and that hardware checksums are not a win (although hardware vlans are). So... I need to know what GigE chipsets I should test. I recently tested Intel GigE cards ... with dismal results... less than half the packets-per-second on the (otherwise) same hardware. Small packets (as in DOS attacks) are a real concern here. I believe that someone here recomended Tigon III based cards ... but I was recently looking through 5.0-RELEASE's hardware notes and couldn't find any mention of Tigon III. A hint on where to buy the cards may be helpful _and_ I'd like to know if the choice might be different for -STABLE (as some of our routers run -STABLE).

As far as I know, all of the GigE cards do hardware checksums anyway. Those which support VLAN de/muxing in hardware are listed in the vlan(4) manpage and in the respective interface manpages (bge, em, gx etc.) -- I think most of them do, if not all. > So...

That's the Broadcom BCM570x chipset (bge driver). It's only inofficially called "Tigon III" because it's based on the Tigon I/II from Alteon. Having said that -- We do have a bunch of Compaq DL360-G2 machines in production, each of which has two of those bge interfaces. We make heavy use of VLANs, and the performance is very good. However, we're running 4.7 (because they are production servers), and our packet profile is probably very different from yours (most of the traffic is NFS, HTTP, SQL queries and similar things).

Nope; lockmgr doesn't have that feature, although all the SMPng locking primitives do, I believe. In fact, I believe that's the source of Julian's question, since I've had a conversation with him about adding that sort of sanity checking. In adding that sort of sanity checking, you want to be very sure we don't break any existing assumptions.

Hmm. No, maybe not... I'm afraid i should change the userland to perform the same as the early startup in the kernel now does. What does your sysctl kern.disks say? As a workaround, you can try setting vinum_load=YES vinum.autostart=YES in your /boot/loader.conf, /and/ remove the start_vinum line from rc.conf.

My kernel is a bit modularized, and with devd, when i insert the card into the running machine, the script framework properly kldloads the respective driver (using /usr/local/bin/smart-loader as suggested in the devd.conf template).

The contents of /dev/ really don't need audited, in a devfs world, like they might be in a non-devfs one. For example hiding rootkits in /dev/wd0./foo or /dev/somedev0/ or whatever isn't really quite the issue it may have ever been. People who read too much into the contents of a devfs /dev should not be too surprised if the results are dodgy. What with cloning and all. -- Juli Mallett AIM: BSDFlata -- IRC: juli on EFnet OpenDarwin, Mono, FreeBSD Developer ircd-hybrid Developer, EFnet addict FreeBSD on MIPS-Anything on FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Fri Feb 7 15:58:30 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id C0DEC37B401 for ; Fri, 7 Feb 2003 15:58:29 -0800 (PST) Received: from 100m.mpr200-1.esr.lvcm.net (100m.mpr200-1.esr.lvcm.net [24.234.0.78]) by mx1.FreeBSD.org (Postfix) with ESMTP id 05ADC43F85 for ; Fri, 7 Feb 2003 15:58:24 -0800 (PST) (envelope-from tdondich@majiknetworks.com) Received: from majiknetworks.com (ip68-108-119-37.lv.lv.cox.net [68.108.119.37]) by 100m.mpr200-1.esr.lvcm.net (Mirapoint Messaging Server MOS 2.9.3.5) with ESMTP id ASY91521; Fri, 7 Feb 2003 15:58:15 -0800 (PST) Message-ID: <3E44493E.7030802@majiknetworks.com> Date: Fri, 07 Feb 2003 16:03:10 -0800 From: Taylor Dondich User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130 X-Accept-Language: en-us, en MIME-Version: 1.0 To: current@freebsd.org Subject: File Corruption in msdos filesystem types Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I was working in some files that were mounted via a msdos filesystem.

No. devfs silently ignores MNT_RDONLY and doesn't support MNT_UPDATE.

Not really..a number of -current binaries use syscalls that are not present in 4.x. What should work is using distcc with the gcc32 port on your stable box. distcc is quite remarkable.

At my previous employer we used Intel EEPro 1000 Server cards with the em(4) driver on FreeBSD 4.5 with nary a hitch and excellent performance.

The follow-on to the Tigon II is the Broadcom BCM570x supported by the bge(4) driver in FreeBSD. This is not what you want. They're certainly cheap to test with, though; the Netgear GA302T sells for under $40 at a few online retailers. -- Where am I, and what am I doing in this handbasket?

Your typical 32bit 33MHz PCI bus is going to be marginal for routing GigE traffic, just due to bus bandwidth limitations, but it'll handle multiple 100BaseTX cards just fine. While a higher-end setup like a Serverworks chipset, with a 64bit, 66MHz bus will handle the traffic better. OF course, if you really want good routing performance on a*BSD platform, you should be looking at a Juniper M20 or M40.

The extended slices were created before FreeBSD 4.3 was installed on my machine. After that, I just kept building world and kernel and upgraded to 5.0. It used to work before GEOM, but then it suddenly stopped.

Is anyone else seeing this? If this is on ATA, try the attached patch. It changes ata_getparam() to not block anymore by reverting to the pre-r1.138 behaviour. This is just a quick hack though, since r1.138 was apparently made to fix probing of some CD-ROMs (so these are broken again by this patch). - Thomas -- Thomas Moestl http://www.tu-bs.de/~y0015675/ http://people.FreeBSD.org/~tmm/ PGP fingerprint: 1C97 A604 2BD0 E492 51D0 9C0F 1FE6 4F1D 419C 776C --sm4nu43k4a2Rpi4c Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="ata-dump.diff" Index: ata-all.c =================================================================== RCS file: /ncvs/src/sys/dev/ata/ata-all.c,v retrieving revision 1.163 diff -u -r1.163 ata-all.c --- ata-all.c 19 Jan 2003 20:18:07 -0000 1.163 +++ ata-all.c 21 Jan 2003 17:01:13 -0000 @@ -514,7 +514,7 @@ /* apparently some devices needs this repeated */ do { - if (ata_command(atadev, command, 0, 0, 0, ATA_WAIT_INTR)) { + if (ata_command(atadev, command, 0, 0, 0, ATA_WAIT_READY)) { ata_prtdev(atadev, "%s identify failed\n", command == ATA_C_ATAPI_IDENTIFY ?

Is anyone else seeing this? This might be caused by ddb not disabling interrupts or by a driver bug (not keeping interrupts disabled, or not using polled mode for dumping so that dumping can work with interrupts disabled, or going near a mutex for dumping). If you call doadump() after ddb was invoked for certain fatal traps, then the 'Context switches not permitted in the debugger' is probably normal because of an old bug in ddb (it doesn't run with interrupts disabled in this case). Try the enclosed patch. Calls from ddb invoked by panic() shouldn't have this problem, but panic() is very likely to hang or die on a lock even before it gets to doadump(). %%% Index: db_interface.c =================================================================== RCS file: /home/ncvs/src/sys/i386/i386/db_interface.c,v retrieving revision 1.69 diff -u -2 -r1.69 db_interface.c --- db_interface.c 21 Sep 2002 18:53:58 -0000 1.69 +++ db_interface.c 21 Sep 2002 23:56:57 -0000 @@ -78,4 +78,5 @@ kdb_trap(int type, int code, struct i386_saved_state *regs) { + u_int ef; volatile int ddb_mode = !(boothowto & RB_GDB); @@ -97,4 +98,8 @@ } + /* XXX is this correctly placed?

How about the following change (patch included) to make the slowdown optional? On my laptop I prefer to do the fsck sometimes as fast as possible. This could be easily made into a rc.conf variable.

It doesn't have the alignment issues that some of the cards do, so you get to avoid the m_pullup() (and the copy that happenes with it, in tcp_input()), since it can scatter/gather to an unaligned address. It's also the first card I'm aware of that does the full range of checksum offloading, without slowing the card down, which (finally!) lets you offload some of the network processing to the card (i.e. it does IP, TCP, and UDP). The card itself does interrupt coelescing in hardware, and you can adjust both the trigger and buffer thresholds from the driver. Using 64bit 66MHz slots, it's possible to keep two interfaces completely loaded, while retaining sufficient CPU and bus bandwidth to actually do other work (though, in general, you will want to tune your stack, and replace the mbuf allocator). About the only complaint I really have about it is that, unlike the Tigon II, now that Broadcomm got their grubby little hands on it, unlike Alteon, they are refusing to make the firmware sources available so people can do useful work in the context of the firmware. Actually, there are some really brilliant things you can do, if you can replace the firmware, that can take you up to theoretical max packets a second very easily and quickly. We were able to get in the neighborhood of 31,000 connections per second with the Tigon III, alll other things being equal, even before FreeBSD added the SYN cache and SYN cookie code. Is there a particular reason you don't like the card, or at least prefer the other card more? -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sat Feb 8 9:34:28 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 7960537B401 for ; Sat, 8 Feb 2003 09:34:25 -0800 (PST) Received: from mike.reifenberger.com (pD9E50DE9.dip.t-dialin.net [217.229.13.233]) by mx1.FreeBSD.org (Postfix) with ESMTP id 636DB43F75 for ; Sat, 8 Feb 2003 09:34:23 -0800 (PST) (envelope-from root@nihil.reifenberger.com) Received: from nihil.reifenberger.com (nihil [10.0.0.2]) by mike.reifenberger.com (8.12.6/8.12.6) with ESMTP id h18HYG9O068982; Sat, 8 Feb 2003 18:34:17 +0100 (CET) (envelope-from root@nihil.reifenberger.com) Received: from nihil.reifenberger.com (localhost.reifenberger.com [127.0.0.1]) by nihil.reifenberger.com (8.12.6/8.12.6) with ESMTP id h18HY6co000707; Sat, 8 Feb 2003 18:34:06 +0100 (CET) (envelope-from root@nihil.reifenberger.com) Received: from localhost (root@localhost) by nihil.reifenberger.com (8.12.6/8.12.6/Submit) with ESMTP id h18HY4At000704; Sat, 8 Feb 2003 18:34:06 +0100 (CET) Date: Sat, 8 Feb 2003 18:34:04 +0100 (CET) From: Michael Reifenberger To: Joerg Wunsch Cc: freebsd-current@freebsd.org Subject: Re: vinum start & -current doesn't work as expected In-Reply-To: <20030207225249.O33219@nihil.reifenberger.com> Message-ID: <20030208181905.Y664@nihil.reifenberger.com> References: <20030207105857.T2514@nihil.reifenberger.com> <200302072056.h17KujgW073866@uriah.heep.sax.de> <20030207225249.O33219@nihil.reifenberger.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=ISO-8859-1 Content-Transfer-Encoding: 8BIT X-Spam-Status: No, hits=-1.3 required=5.0 tests=IN_REP_TO,QUOTED_EMAIL_TEXT,REFERENCES,SPAM_PHRASE_00_01 version=2.43 Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG On Fri, 7 Feb 2003, Michael Reifenberger wrote: ... > > As a workaround, you can try setting > > > > vinum_load=YES > > vinum.autostart=YES > > > > in your /boot/loader.conf, /and/ remove the start_vinum line from > > rc.conf.

Yeah, a prototype Xylan GigE switch blade was done with Tigon-II's and we did a bit of hacking in the firmware. They were pretty cool; we used the usual Xylan SPARC processors on the card only for bus and chassis management and did most of the cool packet stuff in the Tigon itself. > Actually, there are some really brilliant things you can do, if > you can replace the firmware, that can take you up to theoretical > max packets a second very easily and quickly.

Our testing, which mostly comprised throwing a pair of cards into a system, turning on bridging and blasting it with a SmartBits, showed the Intels to be faster with less CPU load. The Intel cards were 2x the price, but still well within our rather permissive budget. When you're putting 4, 8, or even 16 GB DDR RAM into a box the cost of a pair of network cards isn't significant. ;^) If I were buying a card myself, I'd likely go with the NetGear because it's cheap and it works, but you well know I'm a cheapskate.

Not after looking a bit closer. ;-) The only difference ist that the userland "vinum start" uses devstat, while the in-kernel autoscan if vinum.autostart is set uses sysctl kern.disks (devstat is not available in the kernel). Both use the same backend function. So yes, the userland should probably be changed to use the sysctl as well, but that's certainly not the root of Michael's problems. Something else must be the problem there. -- cheers, J"org .-.-. --... ...-- -.. .

Assuming you're running -current as of today, otherwise install include files and libgeom by hand first. Apply this patch in src/sys/geom and make a new kernel. http://phk.freebsd.dk/patch/geom_io.patch Stick these two in a directory and run "make". http://phk.freebsd.dk/patch/Makefile http://phk.freebsd.dk/patch/gstat.c Then run sysctl kern.geom.collectstats=1 to enable collection of statistics in the kernel (reports of the performance impact of doing so welcome!) and then run the "gstat" program in an xterm. Notice that the program uses two ANSI escape sequences directly ("ESC [ 2 J" and "ESC [ H") I didn't want to mess with curses right now. You will get a display like this: dT L(q) ops/s r/s ms/r w/s ms/w d/s mw/d %busy Id 1.010 0 0 0 . 0 . 0 . 0.0 0xc412a580 1.010 0 0 0 . 0 . 0 . 0.0 0xc3fe2b40 1.010 0 44 0 . 21 1.0 23 0.0 1.9 0xc412a400 1.010 0 0 0 . 0 . 0 . 0.0 0xc3fe2680 1.010 0 44 0 . 21 1.0 23 0.0 1.9 0xc3fe2600 1.010 0 44 0 . 21 1.0 23 0.1 2.0 0xc4108e80 1.010 0 44 0 . 21 1.0 23 0.1 101.0 0xc3fe2500 1.010 0 44 0 . 21 1.1 23 0.6 3.1 0xc4108d00 1.010 0 0 0 . 0 . 0 . 0.0 0xc3fe24c0 1.010 0 44 0 . 21 1.1 23 0.6 3.1 0xc3fe2bc0 1.010 0 0 0 . 0 . 0 . 0.0 0xc418c180 1.010 0 0 0 . 0 . 0 . 0.0 0xc4312140 The columns are: dT Seconds in this measurement interval (change the sleep at the bottom of gstat.c to modify). L(q) Number of transactions in queue at this moment in time ops/s Operations per second in this interval. r/s, w/s, d/s Reads, Writes and Deletes per second in this interval ms/r, ms/w, ms/d Milliseconds per read, write and delete (average for interval). %busy Attempted calculation of %busy according to the discussion here. Id A not very random number which can be translated to something meaningfull with the output of sysctl -b kern.geom.confxml Another easy way is to use dd if=/dev/ad0 of=/dev/null dd if=/dev/ad0s1 of=/dev/null ... to identify the various devices if this is important. And as you will probably discover, the %busy is not very calm and the other columns will take a hit every so often too. I can of course make these statistics a perfect snapshot by employing locks around all the updates (that will be cheaper than atomics because there are several fields updated at the same time), and grabbing the lock when I get a snapshot. But doing so will cost us in performance: The actual lock operations, even if uncontested costs something, while it may not affect I/O throughput, it will affect the entire systems throughput. Then there is the lock contention, that is probably not too bad, it's cheap operations and they are not _that_ frequent. I will need to use read(2) or ioctl(2) to pull the data out of the kernel instead of the mmap(2) I use now, since I need a place to grab the lock. That means userland/kernel transitions. A number of intermediate solutions exist, such as flagging the structures while they are being updated (possibly with memory barriers). All it comes down to in the end is: How much of a performance hit do we want to take to collect disk statistics ? Input still very much appreciated...

Look in /usr/src/sys/kern/syscalls.master. You will see that this write() is listed as a system call. If you run the script makesyscalls.sh which is in the same directory, it will create syscalls.c, syscalls.h, sysproto.h, and syscall.mk. If you look at /usr/src/sys/sys/syscall.h, you will see SYS_write defined in that file. You can see the man page for syscall() to see what it does when you do syscall(SYS_write, ...); Look in /usr/src/sys/kern/sys_generic.c, and look at the write() function there.....

I'm not really thinking of running like that, but > I am curious about others' experiences. First, let me answer the question that you really meant to ask but forgot to, namely, ``How much of a performance difference does -O3 make over -O for the kernel/world?'' The answer is ``very little, for most purposes.'' So if you do use higher optimization levels, at least do a little benchmarking to make sure it was worth it. To answer your second question, higher optimization levels usually work, but there *will* be new bugs. I know of several libc problems due to -fstrict-aliasing, and I'm told that the inline assembly for TCP checksumming can still break.

Yes it is. But there were (valid) objections to using in the kernel.

I think you're thinking of dataflow analysis, which I believe gcc does with -O and higher optimization levels. So unless you're using -O0, I would expect that you'd get all the warnings you want. > There are a number of places, particularly on non-i386 platforms, > where optimization actually doesn't work.

Yes, the possibility of being bitten by compiler bugs is certainly higher with higher optimization levels. Alpha with -O2 seems to have been broken for years, and I have seen strange things happen on IA64 as well. But the i386 code generators have received much wider testing and debugging, so there is somewhat less danger there.

There are now four times more lines of warning messages from openssl than from everything else in buildworld combined, if I'm counting this right. In any case, the list of warnings now overflows my scrollback buffer, so it's pretty noticeable. I'm also getting a number of syslog'ed error messages about sshd[14235]: in _openpam_check_error_code(): pam_sm_setcred(): unexpected return value 24 with the system I built on Feb 3rd. However, I do notice there have been more changes since then, so that problem may already be fixed. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sat Feb 8 17:24:35 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 206AF37B401 for ; Sat, 8 Feb 2003 17:24:34 -0800 (PST) Received: from stork.mail.pas.earthlink.net (stork.mail.pas.earthlink.net [207.217.120.188]) by mx1.FreeBSD.org (Postfix) with ESMTP id 7703D43F75 for ; Sat, 8 Feb 2003 17:24:33 -0800 (PST) (envelope-from tlambert2@mindspring.com) Received: from pool0226.cvx40-bradley.dialup.earthlink.net ([216.244.42.226] helo=mindspring.com) by stork.mail.pas.earthlink.net with asmtp (SSLv3:RC4-MD5:128) (Exim 3.33 #1) id 18hgCt-0006Ko-00; Sat, 08 Feb 2003 17:24:32 -0800 Message-ID: <3E45AD75.47C80368@mindspring.com> Date: Sat, 08 Feb 2003 17:23:01 -0800 From: Terry Lambert X-Mailer: Mozilla 4.79 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: David Schultz Cc: Ray Kohler , freebsd-current@FreeBSD.ORG Subject: Re: Compiling with high optimization?

Kris accidently introduced a bug that had to do with whether or not a variable was used before it was initialized.

I just wanted to point out that what's probably a good idea for catching coding errors like uninitialized variables is definitely not a good idea for distributing code for people to run. I wasn't really sure why he was asking, so I tried to look at it from both angles. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message From owner-freebsd-current Sat Feb 8 17:50:58 2003 Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 028A337B401 for ; Sat, 8 Feb 2003 17:50:57 -0800 (PST) Received: from HAL9000.homeunix.com (12-233-57-224.client.attbi.com [12.233.57.224]) by mx1.FreeBSD.org (Postfix) with ESMTP id 531D843F93 for ; Sat, 8 Feb 2003 17:50:56 -0800 (PST) (envelope-from dschultz@uclink.berkeley.edu) Received: from HAL9000.homeunix.com (localhost [127.0.0.1]) by HAL9000.homeunix.com (8.12.6/8.12.5) with ESMTP id h191osYP021335; Sat, 8 Feb 2003 17:50:54 -0800 (PST) (envelope-from dschultz@uclink.berkeley.edu) Received: (from das@localhost) by HAL9000.homeunix.com (8.12.6/8.12.5/Submit) id h191orJm021334; Sat, 8 Feb 2003 17:50:53 -0800 (PST) (envelope-from dschultz@uclink.berkeley.edu) Date: Sat, 8 Feb 2003 17:50:53 -0800 From: David Schultz To: Terry Lambert Cc: Ray Kohler , freebsd-current@FreeBSD.ORG Subject: Re: Compiling with high optimization?

I'm just pointing out that all you need is -O to get that warning: das@bloody-mary:~> cat foo.c int main() { int foo; return foo; } das@bloody-mary:~> gcc -o foo foo.c -Wall -O foo.c: In function `main': foo.c:2: warning: `foo' might be used uninitialized in this function This is one of those things that gcc3 does pretty well, but Sun's javac does very badly. First of all, in Java, the above warning is considered an error (except *maybe* in JDK 1.4, which is broken and slow on IA64 so I can't use it). Second, the dataflow analysis in javac is braindead, so the compiler is almost always wrong. When I get the same warning from gcc, it's usually right unless interprocedural analysis would be required.
