Who's messing with date? it acts as before except if you need to
annotate a stream with timestamps..
Now puting it in logger.. THAT is an unintuitive program to make into a
date adding filter.
Date's job is to output the time.. it makes perfect sense to me to allow
it to append the time to a stream as well.
logger's job is to send data to the syslog system, which already date
stamps things.
It is not designed to be a filter but it already takes file input and
outputs to stderr.
I really can't believe the people who are complaining about this.. I
should have just committed it.
Talk about a bikeshed!

I understand what you are saying; just don't agree with you
that date(1) is the right place to make this change.
Particularly as it is not a filter.
> Now puting it in logger.. THAT is an unintuitive program to make into a
> date adding filter.
Your original intention was to timestamp lines in a logfile.
What better program than logger(1) for that? And logger
already accepts data on stdin.

Which is why I said extend logger if you must. Or a separate
date-filter program.

A disagreement is not a complaint.

We are saying don't even build the bikeshed :-)
In any case *you* asked for our feedback. At least consider
the feedback without impugning our motives.

Thanks for the tips! I forgot that there's the mapping mechanism using=20
libmap.conf. I will use that until the next KDE version arrives. I know tha=
t=20
mapping shared libraries can be a bit dangerous, but I can live with that=20
until KDE 3.5.4!
Ciao,
Christian.

Dear colleagues,
can anyone properly initialize sio0 on this motherboard? With the last BIOS on
both RELENG_6 and HEAD I got
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0: irq maps: 0 0 0 0
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
sio0: type 16550A
Any hints?
Sincerely,
D.Marck [DM5020, MCK-RIPE, DM3-RIPN]

Yes I did, and no data seems to flow through. Both on 115200 and 9600 bps.

amd64 will always print that warning message ("port may not be enabled")=20

they are just stubs so all the tests fail.
What are you testing the port with? Is it enabled in the BIOS?

From my experienc, versioned symbols allows you to avoid about 50% of
library version bumps
but you still need them every now and then.
There are lots of other ABI changes that need to happen that symbol
versionning just can't help you with.
For example, changing argument types.

Hi all,
I am trying to use ggatec(8) on 5-STABLE to mount a device file on a 7-CURRENT
and am seeing the following error:
# sudo ggatec create -vo ro hostname /dev/da0s1
info: Connected to the server: obelix:3080.
debug: Sending initial packet.
debug: Receiving initial packet.
error: ggatec: ioctl(/dev/ggctl): Invalid argument.
error: Exiting.
Any ideas ?

No, you can handle that with symbol versioning too.

I think that the 7-CURRENT version of ggate is incompatible with 5-X
versions, however I see no mention in the man pages.

In the "good old days" when FreeBSD still hat gnu awk as
/usr/bin/awk, it was pretty trivial to do:
ls | awk '{print strftime("%+: ") $0}'
Unfortunately, our "shiny new" awk doesn't have strftime()
anymore. (One of the reasons why I always install gnu awk
from ports and let it override the crippled /usr/bin/awk.)
I don't think it deserves bloating date(1) or even a
completely new tool. There are tools which can do the
job easily and efficiently (e.g. gnu awk, see above).
Just my 2 cents.
Best regards
Oliver

Try using sigaction() instead of signal(), and don't set the SA_RESTART
flag. fgets() should then return with EINTR in that case.
OTOH, maybe stdio catches EINTR and retries itself. Quick check... no, it
doesn't, so it should work in the way you want. The attached program
demonstrates this.

Actually, there were some locking fixes I did in HEAD and 6-stable
recently related to bce_watchdog() (IIRC). I'd check the 6-stable
version of sys/dev/bce/* just to be sure.

Hi,
I am a student doing SoC linuxolator update. The work involved updating
linuxolator to be able to work with 2.6.x (2.6.16 in my case) kernel emulation.
To be able to run 2.6.x emulation I had to implement NPTL, which means NPTL, futexes
and thread area, pid mangling + various hacks to make it work.
This is the first patch meant for public revision/testing:
www.stud.fit.vutbr.cz/~xdivac02/linuxolator26-diff.patch
What works/doesnt work is described here:
http://wikitest.freebsd.org/linuxolator-patch-status
This is not finished but its good enough to be commited. The plan now is to commit this
soon to src (because of coverity testing and more public testing).
How to test:
you have to have i386 system (amd64 is WIP now)
cd /sys
fetch http://www.stud.fit.vutbr.cz/~xdivac02/linuxolator26-diff.patch
patch < linuxolator26-diff.patch
recompile kernel and boot
this patch comes with compat.linux.osrelease=2.6.16 so you dont have to set anything. what will be commited
to src will have 2.4.2 default so everything should work like now. please test with both 2.6.16 and 2.4.2.
What I care about:
- if you see any panics, LORs etc. please report
- pls report if something doesnt work for other reason then sleeping on linuxfutex (this is being worked on)
thnx
Roman Divacky

You can generally assume that things dealing with system internals (like
ggate) are incompatible from one major version to the next. You _should_
assume that everything from 2 major versions ago is incompatible, and be
pleasantly surprised if it works.

But this is a network protocol thing, not just a local command thing.
Ideally, with protocols which often do involve more than one revision of OS,
there would be compatibility code for older protocol versions. Or maybe I
misread the nature of the problem here?

while this is true, if you had read the rest of the thread you would
have seen the words
"without running date for every line".
I even said that it could be done using shell if one WAS willing to run
date for each line.

I cleaned a lot the code, added some extra debug stubs and comments
and get rid of RW_LOCK_EXEMPTED bit.
Please refer to:

I'm sorry. agp.c's change is not wrong. When X is initializing,
allways freeze the machine, so I think that this change is wrong.
But I can get the panic message by other reason.

That's true, but a bit harsh. Julian, we have probably caused
you an inordinate amount of trouble and wasted too much of your
time already with this, so I understand why you would be
frustrated about replies like the one from DES.
I'm sorry if I have, by my replying to the thread, caused you
some of the frustration (especially since I initially thought
this was cool and a nice feature to have and changed my mind
later). Please bear with this last message from me about
modifying date(1), and then I'll shut up until this issue is
resolved by people who know more than me about src/ stuff :-)
> I even said that it could be done using shell if one WAS
> willing to run date for each line.
Yes. But that would be horribly inefficient.
After a fair bit of thought, my reluctancy to agree that a patch
for date(1) is in order is based on at least the following
reasons:
- Making such a change would be a diversion from what date(1)
traditionally does. It's a new feature and it would
probably be useful, but I have doubts about its usefulness
as an inline part of date(1).
- There are countless ways to do the same thing with a
filter, some of which also have timestamp granularity far
better than what date(1) can ever hope to provide (at least
without adding custom strftime(3) format specifiers, which
is a needless diversion from standards).
For example, a Perl-based filter can use gettimeofday() and
provide timestamps with sub-second accuracy. This is not
(currently) possible with strftime(3), which is what
date(1) is based on :(
- Now that this thread has been spawned, people who want to
do something like this can easily find several suggestions
to satisfy their needs, without modifying date. Admittedly
this is a very weak argument for *NOT* adding new features,
but still a thought that raises a few doubts about the
immediate usefulness of the feature.
Just my $0.02 on the topic. If you still think it's a good thing
to have and somebody(TM) comes up with a patch that doesn't cause
people too many problems, feel free to ignore everything above :)
Regards,
Giorgos

I tried it on two different machines and it is the case on both!

Hi all,
I have installed freebsd 6.1-RELEASE on my machine and now samba dont
work, because of a timeout.
I've tried the two versions of the samba ports and none of them work
properly.
Do you have any idea?
Ouput:
osiris# mount -t smbfs //porta1/tmpdown /tmpdir
Password:
mount_smbfs: unable to open connection: syserr = Operation timed out
Otherwise, this is not an password error.
Best Regards,
Carlos Silva, CSilva

Hello.
I am completely stuck. I have a router, that rules three subnets. At first=

there were Allied Telesyn's netcards with realtek chipsets. I am using=20
ipfw+natd and I had like 3,5 megabytes per second with 20 per cent of=20
interrupt load. I had "discarded oversized frame" too often so I've replace=
d=20
two main cards with 3Com 905 and now my xl0 and xl1 never discard frames. B=
ut=20
I saw no speed boost and interrupts were also very high. I have discovered=
=20
some IRQ conflicts and removed them, now I have single device per IRQ, but=
=20
still i have near 20-30 % of interrupt load, when i download something=20
through this router (and natd takes rest % of CPU). Some people advised me =
to=20
use polling, so I've built kernel with HZ=3D1000, polling and tried it.=20
Interrupts grew to 40-50% and speed decreased to 200-300 kb/s, so I had to=
=20
turn the polling off.
I just don't know what to try, to gain at least 9 mb/s, because this is wha=
t I=20
get at home with the same cards, the same processor, with no polling and=20
throgh the same provider.

Sorry, that was the wrong direction.
My solution was:
Add these lines to your kernel-config
#
options SMBFS #SMB/CIFS filesystem
#
# SMB/CIFS requester
# NETSMB enables support for SMB protocol, it requires LIBMCHAIN and
# LIBICONF options.
# NETSMBCRYPTO enables support for encrypted passwords.
options NETSMB #SMB/CIFS requester
options NETSMBCRYPTO #encrypted password support for SMB
#
options LIBMCHAIN
options LIBICONV
#
and recompile your kernel.

Hello
Im planning to test gjournal.
I already read the offical stuff and the examples but I've no big swap
partition.
On this box the swp is 512MB big (not much you see).
Isnt it possible to add a gjournal to an existing ufs2 file system?
cheers

Hi all,
I am using samba-3.0.21b,1 succefully on 6.1-RELEASE-p3 box without any
problem.
But portaudit marks the package like problemed. Also the port has IGNORE
mark and I can't upgrade samba.

my problem is that I am not able to MOUNT shares on 6.1R... its not problem
with samba not working etc.

Actually, with fBSD6.1-CURRENT, some people have problems mounting SMB
shares. I'll try at the kernel-config as Werner-Griessl said.

Did you try using pf instead of ipfw+natd? natd is known to be
inefficient, as the kernel copies packets to and from the userland.
Not sure if this is the cause of your high interrupt load. What does
`top -S' show as the cpu-generating irq?

I think it would be useful to compare the settled loads of the two systems, if
they are otherwise identical, using systat -vmstat 1 and top -S. I'd load the
systems up, leave the tools running, and wait a couple of minutes, then
compare snapshots of the output from both systems. top -S is particularly
informative, as it will tell you which ithreads are burning the most CPU, and
systat -vmstat will tell us the context switch rate and interrupt rates of
various sources.
There are some general optimization techniques that can be applied here -- for
example, if it's an SMP box, you might find that net.isr.direct=1 improves
performance. However, I think the real problem here is the performance
difference, which suggests a problem that needs resolving, rather than
optimization being required up front.

Hi,
the behavior before and after the changes shouldn't differ (as long as
no one changes the sysctl compat.linux.osrelease), but you should
expect strange behavior when you try to build a kernel while I'm doing
the commits...
Bye,
Alexander.

trap 30 means we got an interrupt vector we aren't expecting. You can try
installing custom interrupt handlers to see which IDT vector is actually
being triggered.

No problem here (with a mount_smbfs -I host -W workgroup "//....") on

The (very basic) samba server runs 6.1-RELEASE.

I already started... and I don't want to commit some parts (the linker
stuff which allows to use the module on amd64).
It is also not used by default, as long as we have 2.4.2 for the linux
version, no new functions will be used by glibc. So there is no change
in behavior after the commits. I tested with acroread (which has issues
when run with a 2.6.16 compat.linux.osrelease version, where the new
functions are used by glibc).
So this gives us:
- coverity reports for the code *before the end of the SoC*
- no change in behavior in the default case, since the new calls
aren't used by glibs as long as... see following entry
- easy testing possibility (sysctl compat.linux.osrelease=2.6.16,
defaults to 2.4.2)
- more eyes on the code
Yes, there are issues with the code, but you will not see them as long
as you don't *explicitly opt-in* to test the new parts.
So I finish the commits now. In case someone has some very strong
reasons for a backout, I do it, but it would be nice if the backout
request (if any) is made after having a look at the default behavior of
the linuxolator after I'm finished with the commits.
Bye,
Alexander.

Why the rush? I'm sure Roman will be around even when the SoC is over.
Also, I'm not asking you to wait a month, just a couple of days until
more people have had a chance to look at the changes.
It's a bit unreasonable to say "here's a patch, please look at it" and
commit it less than a day later.

Those are not valid reasons to commit unreviewed and potentially wrong
changes.

Forgive me if I seem to misunderstand things here, but:
We've had ULE in -RELEASE, even when it was known to be broken. The reason
that was acceptable was its "Opt In" nature. (And, thus the problems when it
wasn't opt in). The fact that this can be easily turned off, and on would,
in my opinion, make the issue of it being committed pretty irrelevent.
I see this as fairly important code for Linux compat going forward, so a
quicker release to -CURRENT, when it can be disabled, which allows it to be
cleaned up and prepared for the next -RELEASE seems like a good move.
Compare this to some of the audit and bsm bits that got put in, for example.
I don't believe the patch is the "full version".... I'd have to ask Roman
about it.
Basically, if its wrong, but isn't enabled by default, -CURRENT is as good a
home as any for this sort of thing, in my opinion. It certainly widens the
pool for testing...

Some comments:
- You shouldn't add new nested includes (such as in
amd64/linux32/linux.h), especially sys/lock.h, sys/mutex.h, and
sys/sx.h. (If you need to examine mutex internals you would include
sys/_mutex.h in a header, but for normal API usage you need to
include sys/mutex.h and sys/lock.h in the appropriate C files.
sys/param.h is far too large of a header to be used in a nested
include.
- Check style(9). For example, block comments should look like this:
/*
* This is a really long comment that takes up
* more than one line.
*/
rather than this:
/* this is a really long comment that takes up
* more than one line
*/
- You use the EMUL_LOCK in em_find() to look at p_emuldata but don't
hold it when writing to p_emuldata in linux_proc_init(). There you
only hold the proc lock.
- You should probably hold the proc lock until after the wakeup()
in linux_proc_init() since the pfind() / proc_unlock() is what holds
a reference to keep the child from going away.
- In linux_proc_init() you pass EMUL_LOCKED to em_find() in the CLONE_VM
case when the lock isn't held.
- Personal style: please use malloc() and free() rather than MALLOC() and
FREE(). We haven't inlined malloc() in a long, long time and the macros
are really there for older code.
- You tsleep() in linux_schedtail() while holding one lock and do the
wakeup() in linux_proc_init() while holding no locks. You've got lost
wakeup races that way that you work around by having to use a goto and
a sleep with a timeout.
- You should include the appropriate header to get the declaration of 'hz'
rather than just adding an 'extern' directly in your code.
- In futex_get() you don't handle the race of two concurrent creates.
- In futex_sleep(), you probably should be using an interlocked sleep such
as msleep() or cv_wait() to avoid lost wakeups.
- In futex_sleep(), you should probably loop rather than recurse to avoid
blowing the stack.
- In futex_atomic_op(), if you take a page fault on one of your operations
it's going to blow up because of the page fault during a critical section.
Your futex ops should be atomic (perhaps you can do them all using
casuptr()?) and you shouldn't use a critical section here.
- You should stick the sx locks in a header and not litter 'externs' in
source files.
- Should come up with a better name than 'schedtail' for the eventhandler
in fork_exit(). Maybe 'process_fork_exit'?
- You should probably ask Peter to review the link_elf_obj change. An
alternative is to use linker_lookup_set() in your module load routine to
lookup your linker set details.
- Regarding the locking, I'm not sure why you have the two separate sx locks,
and why you don't just merge them into a single lock instead.

I'm having no trouble now. There were some problems in STABLE for
awhile where one needed to add the NETSMBCRYPTO. I'm not sure if that's
still the case, though I still have it in my kernel. There is a notice
that it is no longer necessary in CURRENT /usr/src/UPDATING.
mount_smbfs is working for me now, however. This machine is running
6.1-STABLE with samba 3.0.23,1

Yes, but first he will take a vacation, and then he will not be
available as much as he is now. And maybe Coverity will detect a bug
which we search currently but can't find (don't know how likely this
is, but it is at least possible).

I thought about this before deciding to commit it. Most of the code was
available in P4. Those people with real interest already had a chance
to look at it, or they didn't had time to do so. If they didn't had
time to have a look at it, who knows if they have time to do it now?
There's always someone who says "oh... if you waited 2 days longer...".
That's not the only reason. Tomorrow my holiday is over and I have to
catch up at work. Today I have plenty of time to commit urgent issues
(e.g., tinderbox breakage). And at the upcomming WE I may not have
enough time to do what I do today.
Additionally, the work is a little bit stalled currently, we need more
testers of the new code. There are a lot of people out there which want
to test, but don't know how to patch or fear to do something wrong when
they patch. With the approach I've taken, they just need to run a
sysctl (compat.linux.osrelease=2.6.16) and they can test. All which
don't want to test just don't need to care about it.

Uhm... how many percent of code committed to current is reviewed before
it is commited? How many percent of the code I committed is not
reviewed and how much is this related to the amount of unreviewed code
committed in a busy week?
I'm running a kernel with this changes here and since I didn't enabled
the new code with the sysctl, I don't see any difference in the
behavior of the linuxolator. The potentially wrong code isn't active.
It's like loading the linprocfs module but not using it.
Bye,
Alexander.

I suppose that this is in fact my change. I'm not committing it exactly because
I cannot obtain any review from Peter.
And, it seems that this is not committed.

Finished.
On amd64 not everything is supported like on i386, the catchup is
planned for later when the remaining bugs in the new functions are
fixed.
To test this new stuff, you have to run
sysctl compat.linux.osrelease=2.6.16
to switch back use
sysctl compat.linux.osrelease=2.4.2
Don't switch while running a linux program, strange things may or may
not happen.
Some reviews are already flowing in which point out some deficiencies
in the 2.6.16 case. The default case (2.4.2 as before the commits)
isn't affected.
Bye,
Alexander.

Right. I didn't committed this part because jhb asked to do it
differently or to ask Peter about it.

Please change this so that the two fields are on separate lines.
Also, is there a reason you're using "unsigned long" and not "l_ulong"?
On amd64 long are 64bit long while on i386 they are 32 bits, so there
might be problems, if you're trying to 'emulate' 32bit linux programs on

That is possibly sketchier as if an ABI always sets p_emuldata on fork/exec
and only curthread accesses curproc->p_emuldata you can probably just not have
to do any locking at all as it will actually be effectively read-only. The
emuldata fields can have different strategies in different ABIs because they
will be used differently. Note how so_emuldata is locked by SOCK_LOCK() in
the Linux ABI, but isn't locked in the svr4/streams code because it's set on
socket creation and static until socket close.

Well, in this case he's already holding a lock. If he always holds a lock
when accessing and modifying refs, then refcount_*() would only add overhead.

See above, but there is another concern here in that once you drop the proc
lock, the 'p' process might go away, be free'd, etc. (Especially if you are
preempted right after the PROC_UNLOCK())

In this case it is a workaround for lost wakeups since it's not an interlocked
sleep and wakeup. :)

Actually, for this he is fine, as the proc lock is sufficient to access
p->p_pptr, and the parent process can't go away w/o acquiring the child's
lock and reparenting it to init.

Isn't he holding the wrong lock (emul_lock vs emul_shared_lock)?

Then maybe we need to change our Coverity setup so that it's able to
look at trees in perforce as well.

Not really. I haven't looked at the changes in p4 not because I'm not
interested, but because they were a work in progress. I'd rather look at
"commit canditates".

If you don't have time to commit something you can always ask someone
else to do it for you.

You could have released a sys/ snapshot tarball?

Not enough.

I don't want to sound harsh or like I'm doubting Roman's ability, but
most of the unreviewed code that gets committed comes from people who
have more experience than Roman and who usually "own" the part of the
kernel they are touching.

Suppose you have two threads like so:
thread A thread B
FOO_LOCK(); ...
if (foo) ...
FOO_UNLOCK() FOO_LOCK()
... foo = 1
... wakeup(&foo);
tsleep(&foo); ...
... FOO_UNLOCK()
thread A isn't going to get the wakeup from B. The solution is an interlocked
sleep where you release the lock and put the thread to sleep as an 'atomic
operation'. If you are familiar with pthreads, this is why pthread condition
variables take a mutex argument to their wait functions (and why in the
kernel cv_wait* and msleep() both take a mutex arg), they use internal
locking to atomically drop the lock and block to avoid that race.
interlocked sleeps aren't likely to be implemented for sx locks, but I will
need to add them for rwlocks before too long. For now, if you stick with
mutexes you can use either condition variables or msleep() to avoid this.

Yes, but this is FreeBSD, and all the other process related eventhandlers are
called process_<foo>. :) A generic eventhandler might be used by more than
just the Linux ABI.

What I did for my debug kernel modules is something like this:
struct crash_event {
const char *ev_name;
void (*ev_handler)(void);
};
#define CRASH_EVENT(name, function) \
static struct crash_event function ## _crash_event = \
{ name, function }; \
DATA_SET(crash_event_set, function ## _crash_event)
#define MAX_EVENT event_max
static int event_max;
static struct crash_event **event_start, **event_stop;
Then in my module event handler:
switch (cmd) {
case MOD_LOAD:
error = linker_file_lookup_set(module_file(module),
"crash_event_set", &event_start, &event_stop, &event_max);
if (error)
break;
Here's a sample foreach loop:
for (ev = event_start; ev < event_stop; ev++) {
/* Skip null event 0. */
if ((*ev)->ev_name == NULL)
continue;
printf("%4td %s\n", ev - event_start, (*ev)->ev_name);
}
and here's a sample index operation:
if (ev < 0 || ev >= MAX_EVENT) {
printf("crash: event %d is not defined!\n", event);
continue;
}
evp = event_start[ev];
printf("crash: %s\n", evp->ev_name);
evp->ev_handler();
(If you want to see this specific module more, you can view it
at //depot/projects/smpng/sys/modules/crash/crash.c. There's a
crash2/crash2.c that is similar as well.)

I think it might be prone to races though. If you are almost always acquiring
the same two locks in lockstep, then all you are doing is adding overhead.

Maybe. I think those should be merged into one lock anyway. :)

Could you use gdb to generate frame debugging information for the frame above
nfs_rephead() (nfsrv_symlink()) also, please? I'm a bit puzzled as to how
things got into this state, as under normal circumstances, nfsm_reply() is the
source of the nfs_rephead() call, and the NFS mutex is acquired the line
before the call to nfsm_reply().

People tend to have enough on their plate already. And there where some
parts in the entire patchset which I didn't committed because of a
reason. So I wanted to handle this myself.

And then people do a cvsup or something else which breaks it and they
request help... I'm around on at least current@ since 3-current and if
people just need to turn a switch to test something, everything is fine.

This doesn't help when the code in question isn't owned like the
linuxolator. Because most of the new code will not affect the rest of
the system (only linux programs, if at all), I don't think committing
this now was a big mistake.

it used to be one lock, but it caused more problems then now...
pls, let me fix all the issue and then judge, ok? :)

Hi, I recently encountered build failure with libmagic
for this one month.
My investigating shows that intermediate executable 'mkmagic'
fails to detect the termination of some description of entries
which is longer than expect.(According to contrib/file/file.h
the length is MAXDESC=64.)
The following is a workaround for it. Is it known problem?

For my case, although I did comment on some p4 changes, because it was a WIP,
I waited to see how things would develop with the intent on providing more
feedback when there was a commit candidate. I was not aware that you were
going to commit the patch until I woke up this morning and saw it started
going into the tree. :) That was the only thing that struck me as a bit odd.

Dmitry,
Could you please try natd+kqueue patch from
http://www.freebsd.az/patches.html and report results (difference it
made etc etc) ?
I did not have any chance to test it in heavy load environment.yet.

Ah, all makes sense now. I didn't realize that nfsm_srvpathsiz() was a route
to nfsm_reply(). I'll investigate how best to fix this this evening. Similar
bugs may exist elsewhere in the NFS server, and will presumably turn up during
mbuf starvation.

I agree absolutly with committing this so that more eyes can see it
in a neasy way and so that it can get more testing. If there are instabilities,
then we can live with it for a few days.

linux emulation on amd64 has been broken for several days.
acroread and openoffice both drop core. These changes

Actually, it increases the likelihood that new bugs will increase the
difficulty of isolating existing bugs.

I'd like to see this handled better in the future, myself. In the past 24
hours several reviews have come in -- unfortunately, all after the commit,
because almost no time was given for the reviews to be done before the commit.
Given that there have been several replies on the perforce list indicating
that sections of the changes weren't yet in an acceptable form for committing
(i.e., broken), waiting for that to settle out before committing makes a lot
of sense. -CURRENT is here to provide communal testing, but that doesn't mean
that broken code should be committed intentionally.
Over the past 3-4 years, the standards for committing code to -CURRENT have
gone up *significantly*, and -CURRENT should not be considered a
"free-for-all". It's the base branch for an enourmous amount of other work,
and if -CURRENT gets broken, that holds up all the dependent work. Waiting
three or four days after a patch is posted for reviews to come in is a
reasonable minimum expectation for a large set of changes, especially when
it's clear that there are people out there willing to review the changes (vis
P4 submit replies).
We have Perforce available for exactly this reason: works in progress can
remain outside the tree until they can be adequately reviewed and tested,
rather than having to be committed quickly in order to keep them in revision
control. This became critical a few years ago when it became clear to
everyone that the project had grown to a point where having the "-CURRENT can
be broken at any time" assumption wasn't sustainable, as it meant -CURRENT was
broken all of the time. We can't go back to that, and that means that
everyone who is committing to -CURRENT needs to hold themselves to high
standards of review and testing.
I.e., I think this commit was a mistake. I'm not asking for it to be backed
out, but given the uproar it's caused, and the amount of immediate feedback on
problems in the patch, waiting another two days to get that feedback and fix
the problems is a minimal expectation for committing to the kernel.

the futexes are not 100% working which is different from broken.
it passes my pthread tests and its able to run quite complicated programs (firefox, opera)
the problem is (for example) with realplay which hangs waiting on a futex when I attempt
to play a file. I noticed that this behaviour changes based upon what pid I copy out
to the parent thread (when I copy linux-tid ff/opera works and realplay not, when I copy
linux-pid ff is broken, realplay works). if anyone has an idea what can cause this
feel free to tell me.
the point is - other people might see what the bug is. I dont see it.
what commiting this code into src means?
1) more eyeballs to review
2) coverity run - I strongly suggest extending coverity to run on some p4 branches
3) some panics etc. might be revealed
4) the commit is almost 100% self-contained and doesnt break anything
while I agree that Alexander could wait 2-3 days in general case I also know his reasons
why he commited it so fast - his vacation ends and he wanted to devote today to integrating
this stuff into the cvs. On the other hand I've seen too many patches which got never integrated
that I am glad this one is different.
my 2 cents

jhb asked for debugging infos and I tried to push people for them too.
So far nobody helped with the necessary debug stuff. People with
interest in getting this fixed can coordinate with jhb, it is
independent from the SoC stuff...

Hello,
I'm glad to post the link to the experimental version of the new
BSD-licensed nss_ldap, that was written during SoC. It can be downloaded
as a port from here:
http://www.rsu.ru/~bushman/nss_ldap/nss_ldap_bsd.tar.gz
nss_ldap_bsd currently supports "passwd", "group" and "services" nsswitch
databases and rfc2307 schema. It's configuration file is mostly compatible
with PADL's nss_ldap's configuration file.
Additional information about nss_ldap_bsd development can be found here:
http://wikitest.freebsd.org/NssLdapRewritten
The main goal of the nss_ldap_bsd is to be compatible and
interchangeable with PADL's nss_ldap, but to be licensed under BSD
license and to be more flexible and easily extendable. It is also possible
that nss_ldap_bsd would be merged into the tree along with OpenLDAP.
Please try it and send me your comments and suggestions.
With best regards,
Michael Bushkov

I was trying to get a Linux binary to run
(http://filter24.org/seq24/), and was having problems with linking, so
I messed around with ldconfig a bit and somehow ended up breaking my
system completely. The command I ran before everything broke was
"ldconfig -elf /usr/compat/linux/lib", which I now realize was not at
all what I wanted to do. Now when I try to boot FreeBSD, even in
single user mode, I get the folowing:
libexec/ld-elf.so.1: Undefined symbol "__stdoutp" referenced from COPY
relocation in -sh
libexec/ld-elf.so.1: Undefined symbol "__stdoutp" referenced from COPY
relocation in sh
It then asks me for the location of my shell, but keeps giving the
errors above no matter which shell I choose (/bin/sh being the obvious
one).
I'm running FreeBSD 6.1 (and have been since it came out, so this
shouldn't have anything to do with upgrading). I know I did something
monumentally dumb, but how can I fix things?

Firefox and Opera work. The same is true for a lot of programs which
come with linux_base-fc4 (they didn't worked without the patch when
osrelease was set to 2.6.16). So it isn't totally broken. What it buys
us is reports about more programs which may work or not. For those
which don't, we may get a report about an open source program which
fails. And knowing about a broken program where can get the source and
compile a debuggable version would help in debugging a lot. ATM Roman
can only do a rough guess what's wrong.
Bye,
Alexander.

Use /rescue/sh as your shell (it's statically linked) and then use
/rescue/ldconfig to fix the databases.

I've tried to get more info. Unfortunately, the core dumps
(that I've been able to get) do not reveal anything beyond
what John already knew. See Kip's quote above on why finding
this already elusive bug may become much more difficult.

Thanks to both of you. I used /rescue/sh, remounted / read-write, and
re-ran ldconfig to get everything working again.

Try running `/rescue/sh'.

If you don't switch on the use of the new code with sysctl, you don't
see a difference. acroread works on i386 as before when you don't use
sysctl. The code which is known to have some issues (futexes) isn't
available on amd64 (at least not the MD parts), so you will notice if
acroread uses the new code or not. If it tries to use the new code for
some strange reason (I would be surprised if it does), we are able to
come up with a patch which disables this part very fast (actually some
parts are already disabled there).
Bye,
Alexander.

A lot of the new code isn't used at all if nobody enables the use
(sysctl compat.linux.osrelease=2.6.16). The code which is changed and
is used even with osrelease=2.4.2 is not much. Reviews of those parts
of the code didn't revealed much (mainly name change suggestions and
style issues). Reviews of the unused by default part of the code
revealed some issues. Some of them may be related to what we see as
bugs. The parts of the unused by default code which we know is not bug
free is important (futexes), but not totally broken. When activating
this unused by default code, a lot of programs work, which didn't
worked when changing osrelease before. These programs are some small
ones, like bash, ls and other stuff which comes with linux_base-fc4 and
some large and complex ones like Firefox and Opera.
So a lot of the new code already works (if you activate it) and only
parts of it aren't bug free (ok, this may be a little bit over
enthusiastic, I can't prove that there are no bugs, but I think you get
the point).
I also checked if the programs with issues just work fine as before
when the new code isn't activated. So I decided to commit this, after I
checked that I don't introduce a regression (it is very easy to let
acroread fail if you have a PDF file which exposes the bug). If this
wouldn't have been the case, I wouldn't have committed this.
So yes, I have committed code which is known to be broken. But not
everything is broken, and it only breaks programs, if you tell them to
use new features *and* if you use programs which trigger the bugs. And
the best thing is, you don't need to rebuild your kernel to switch
(like with SCHED_BSD and SCHED_ULE, for example). Apart from this, the
linuxolator is not the VM, VFS or some other high risk subsystem. If it
breaks, don't use it. I'm not aware of a linux application which is
necessary to develop changes for the rest of FreeBSD. So this does not
slow down other developers (except they want to participate in this
discussion...).
Robert, I agree with you about the higher standards in -current, and as
such I made sure that it doesn't break the world or panics the system
in the default case. But after all, this is -current and not -stable. I
use it on my desktop system since 3-current, but I don't expect it to
work after an update. If a change by someone else breaks my desktop, it
is my own fault. It is not a production quality branch.
We can't expect everything to be bug free right away, and to fix some
bugs we may need some more use cases until we can narrow down the
problem. If this can be done by committing code to -current and
enabling it with a switch, a lot of people will give it a try. If it is
only available as a patch, you will not get nearly as much feedback.
Instead of talking about the commits, I suggest to give it a try and to
immediately report regressions in the osrelease=2.4.2 case (that's the
default). So far we are not aware of regressions.
Roman already fixed some issues in p4 which showed up in immediate
reviews. Some of them are NOPs from a functional point of view (style,
moving code to other places, ...), some of them fix races in the new
(and unused by default) code.
For the curious ones: the code is "activated" by changing osrelease,
because the glibc behaves differently depending on the osrelease. It
makes different syscalls based upon the linux kernel version. So if
there's a program which tries if a syscall does not return ENOSYS
instead of checking the osrelease, it may fail. If you are aware of
such a program, please tell us about it.
Bye,
Alexander (going to bed now).

I have not tried to build/use CURRENT for a bit, but I did a cvsup of a system
with that on it last night, and I find that it falls over in make depend. This
is just trying to build an i386 GENERIC.
Known problem?? Suggestions?
Thanks,
Jack

Oh, it's natd. Now I see, but I just don't get it. I know that natd is not=
=20
efficient but, as I've said, at home I have 9 or almost 10 MB/sec through t=
he=20
natd, while at this particular server I see only 3,7 MB maximum. I've tried=
=20
now to turn all the natting off and tried to download a file and got like 9=
=20
MB/sec, so it is natd who loads the system up.
Someone advised me to use pf or ipnat, but I never did that before and hear=
d=20
that this nats have some limitations (like ipnat can't translate icmp packe=
ts=20
or something). Furthermore I can't stop using ipfw, so pf is automaticly=20
excluded. Maybe there are some more advises? I don't really want to have to=
p=20
performance with this router, I just want to raise it a bit, to at least st=
op=20
loosing control on this router while someone is watching movie through it -=
=20
ssh session becomes slow, so I type one letter per minute in this case.
Well, if there is nothing I can do, I will stay with it, things are not tha=

I remember this as well, and I *vaguely* remember looking into
fresh NetBSD sources and seeing it was already fixed (I may be
equally mistaken, as it was a while ago).

Send me the following in private email:
ipfw config
natd config
an ascii-art picture of your network would be good
ifconfig and netstat -r output..
I will see if there is something in your config that is inefficient.
also, you could try profiling natd...

I have tried to rebuild 1.5 but that did not help, which made me
conclude that it is related to libraries or build/linkage.

To be very frank, I'm using it on my personal laptop, which means I can
bare such hiccups. OTOH, I'm using -CURRENT because acpi was broken on
6.1 for my machine in addition to the fact that I'm a developer to be :)
As of now, I have:
FreeBSD 7.0-CURRENT #2: Sun Aug 6 10:55:25 AST 2006

Java HotSpot(TM) Client VM (build 1.4.2-p8-root_15_aug_2006_11_24, mixed

This is the output of my libcheck, where I think I have the problems:

I don't think this was mentioned before. IMHO, this is worth
mentioning in the linuxolator documentation because it's not
immediately obvious and it's likely to bite someone in a non-
obvious way.

General rule is to wait an hour or so and try another CVSup. If that
has the same problem and you haven't seen it mentioned here, try
posting the tail of the make (enough to see the error).

You appear to have omitted the systat -vmstat 1 output.
BTW, there are typically three influences on processing cost for traffic:
packets per second, size of packets, and contents of packets. In the case of
natd, the contents are almost irrelevant, so the costs are really based on
number of packets processed, and the size of the packets. You compare the two
systems in terms of bandwidth, which is more often a property of packet size.
Could you compare the systems in terms of number of packets per second through
the system? As each packet requires two (or more) system calls for natd, lots
of small packets can cost more to process than a smaller number of bigger
packets. If your home system is processing larger packets, it may use less
CPU than the same system processing many smaller packets at the office, for
example.
Finally, are you running any tools such as tcpdump, trafshow, etc, which use
bpf? Any additional programs that perform per-packet operations will result
in additional per-packet context switches, forcing full context switches
between processes, not just switching in and out of the kernel, which is
lighter-weight. This can have a significant impact on performance, perhaps
more significant than expected.

natd runs in userland so every packet has to be pushed out to userland,
processed and pushed back into the kernel. The vast majority of the
overhead is the userland/kernel transition so natd gives you a basically
fixed pps rate. Your throughput will vary depending on the packet size.

Some time ago, I switched from natd to ipnat at work because the
overhead was getting too much. (I've also switched hardware so I
can't give you direct performance comparisons). I have found some
problems with IPfilter in -stable when combining ipfilter/ipnat,
stateful filtering and conditional NATing (ie a packet to B gets NAT'd
to C only if it came from A). (The same combination works in IPfilter
3.x on Solaris.) Normal filtering and NATing works OK.

What does exactly prevent from linking shared libraries against libc ?
In this post [1] Warner Losh states that doing so would solve some
problems (probably the one we are talking about, albeit firefox-bin being
linked against libc.so.6 would conflict with libthr.so.2 being linked
against libc.so.7 -- how rtld(1) would handle this ?), but it will
also create so problems. What are they ?
[1] http://lists.freebsd.org/pipermail/freebsd-hackers/2006-April/016143.html
I've added Warner in the Cc: list.
Thank you.

As I understand, the current state of not linking dso with libc
comes from the time of RELENG_4. There are (were) two libc's: libc
and libc_r. Since both libraries provide same symbols, existence of them
in one image would cause the havoc. Dso cannot know in advance, whether
the final image would use libc or libc_r (the only exception is dso
that uses threads by itself). As result, no -lc for dso.
Moreover, when the -lc switch somehow slipped in (I remember this for libGL=
.so),
it causes huge problems with threaded programs that tried to use that dso.
The current way of linking simply have not changed since then.
For real symbol versioning support, linking with libc is the must. And, now
this is possible due to single libc and separation of libpthread/libthr into
separate dso.
Resulting system will be much stricter with respect to mixing dso's from
old-libc system and new one. This is never was supported, but, for instance,
x11 libraries compiled on RELENG_6, can by used on CURRENT without much
problems. After that change, no such frivolous mixing will ever work
for bumped libraries version.

It should be mentioned in the official docs that a non default value =20
may change the behavior of linux programs (in -stable you may see =20
coredumps when you change the sysctl) and that bug reports with a non =20
default value will not be taken care of.
The intend is to change the default value to 2.6.x when the code is =20
stable enough. So we don't need to name specific values for osrelease, =20
I think.

Hi,
This error was due to old nsswitch.h - nsswitch was significantly extended
in CURRENT, including proper support for "services" nsswitch database.
I've fixed the port - so now everything should be ok (on RELENG_6 and
below "services" database would be unsupported, though).
Thanks for trying this thing out!
With best regards,
Michael Bushkov

Revision 1.1.1 does compile.
It did work only after uncommenting all 'pam_*'
directives in the old nss_ldap.conf
Either you should use a nss_ldap_bsd.conf of ignore all
unwanted directives.
Thanks anyway for your efforts.
Keep on the work!
Now if only I had the whole nss/ldap/cache/* stuff in -stable
(and -current of course)!
Watching a simple `truss ls -l /home/` makes me wonder if I did
the right decision when thaking the LDAP road :-(

nss_ldap would be hopefully merged into the -current along with OpenLDAP

FYI, 'show sleepchain <pid>' will directly show the deadlock in the future. I
have a gdb script equivalent I can give you to run on the core dump if you

I can not install ports onto these machines. They are appliances.
I will simply put the unhancement in out own cvs tree, and the
enhancement will be private.
I'm still comletely amazed that no-one but me thinks this is a good idea
as it seems absolutly
obvious to me and it doesn't affect date's usual behaviour in the
slightest.

Hi Marcel,
You have mentioned that you have gdb6 fully working on FreeBSD/powerpc.
Can you send me those patches for integration into gdb6 port?
Current version doesn't work on live program and unfortunately I don't
have time to track this issue down.

Which version is that ?
I have some patches for 6.0 in
http://people.freebsd.org/~grehan/gdbsrc.tgz
.. which I'm still trying to find time to integrate into -current :(

Sorry about the delay.
The problem persists with a fresh 6.1-STABLE kernel (rev 1.91.2.16
2006/08/10).
When I force the duplex on both sides, I still have to manually bounce the
interface state post-boot. I still get "bge1: 2 link states coalesced".
It seems to perform well once that happens.
If I leave it in auto-media, it comes up at 100/half duplex, which leads
to unusable performance. 100/half duplex is technically impossible
anyway.
I doubt the cause of this problem is the driver at this point. It can't
be the switch. This Broadcom chipset must just suck.
I will just throw a dual-port em(4) in this machine instead. I will make
sure to let our Dell sales rep know we're not interested in purchasing any
more systems with Broadcom chips onboard.
The PE 1950/2950 better not have this problem.

Some Linux applications have been on strike against new Linuxolator
(sysctl compat.linux.osrelease=2.6.16) and new ports (linux_base-fc-4_7
and linux-xorg-libs-6.8.2_5).
Mozilla 1.7.12
Firefox 1.0.7
Adobe Reader 7.0.8
At the same time, Firefox 1.5.0.6 goes out on strike from time to time.

I'd also find this handy, as have many a time resorted to a Perl script
to achieve the same thing. It does seem an odd fit to the "date" command
(date's job isn't really anything to do with logging), but there is
merit in the fact that it avoids having to re-duplicate all the date
parsing and formatting code that already exists within date in another
program...
I sympathise with the situation re: appliances, and the fewer programs
you can get away with in such a situation, the better!

I think it's useful, even if there are many other ways to do it, including
scripts, ports and other tools that may (or may not) triple the effort to
get something done just because of purist reasons.
My suggestion, if you happen to reconsider about having it only for your
local usage, is to instead use a long option, like "--stamp" or
"--timestamp". -s collides with GNU date set option, and people sometimes
forget if they're in a BSD or GNU box (I do).
I'd have sent this mail before, but I got shaky as I'm new here and because
of the huge pressure for not committing such addition.

I wouldn't call it huge pressure.. it was 2 for, (now 3), 3 against and
about 200 who couldn't care.
It's just that the ney sayers always scream loudest.
BTW I chose 's' without any research.. Date only has the short getopt so
'--' doesn't work, but
there are lots of unsed letters.. a quick survey suggests maybe -p (pipe?)
(suggestions welcome) my favourites of s and f are already used on one
system or another.

I found it by grepping for osrelease. The comment is buried in
the FC4 update and not immediately obvious. I was thinking of
it being documented in (eg) linux(4).

What is the plan for the 2.4.x code? Will it be maintained (in which
case, this should be documented), left to rot or explicitly deleted?

My running environment:
1. CVSup-ed source tree and port tree on August 15th 12:20 (calculated for
GMT)
2. sysctl compat.linux.osrelease=2.6.16
3. New ports: linux_base-fc-4_7, linux-xorg-libs-6.8.2_5,
linux-gtk-1.2.10_4 and linux-gtk2-2.6.10
Here, Adobe Reader 7.0.8 doesn't work at all but its beautiful Adobe Logo.
Mozilla 1.7.12 (GTK 1) and Firefox 1.0.7 (GTK 2) don't work at all but
their corpse processes. Firefox 1.5.0.6 (GTK 2) works occasionally, so that
I can write mail to you in it.
I'm afraid that debugging those large programs is difficult. Their strike
probably has something to do with userland runtime libraries such as GLIBC
and XLib.
I don't know the meaning of kernel messages:

Yes, it is mentioned for those which did change it back in the days =20
where it didn't changed anything in glibc and updated to fc4. lang/icc =20
was a bit picky about the compat.linux.* sysctls a little bit longer.
Anyone with enough mdoc-fu listening for the linux(4) change?

The 2.6 code is an extension to the 2.4 code. The 2.6 one is needed =20
for newer FC releases. So the current sysctl stuff is just a disabling =20
of some code in some syscalls. The goal is get stable 2.6 extensions =20
and to forget about the 2.4 downgrade (removing the part which =20
disables some stuff currently, the rest is needed).
So no need to document the effects of some specific values for =20
osrelease, it's enough to say that only the default is supported, a =20
non default value may cause unwanted behavior and bugreports should be =20
submitted with default values.

having the ability to run older linux may be a good thing..how good is
their backwards compatibility.. I've heard of spme people being stuck on old
versions of linux.. maybe the sysctl could stay if there is a problem
to solve.

I noticed this claim earlier in the thread, just to clear up the
apparent confusion, 100/half is not just technically possible, but (was)
quite widely used. Before switches became as cheap and widespread as they
are now, 100Mbit Hubs were not uncommon.
Even 1000/Half is technically valid (and gigabit hubs do exist, allthough
they never became very popular). The first standard to abandon support for
half-duplex CSMA/CD operation is 10-gig Ethernet.

Are you willing to take care of the old linux userland infrastructure =20
in ports and to provide security support for old linux binaries? More =20
recent linux binaries (e.g. FC5) will not run with 2.4.2 (glibc checks =20
for the linux kernel version).

Clarification: the sysctl will stay, the code which disables some =20
parts based upon the value of the sysctl is supposed to go away (ATM =20
it's a bad hack which checks the osrelease number *on every call* of 2 =20
functions).
Anyone with interest in this is free to take care of this, as long as =20
they coordinate with the people which work on the current =20
infrastructure on emulation@ regarding the userland/security stuff and =20
the kernel. Until someone stands up and shows results/progress, this =20
is scheduled to vanish in the future.

Obvious to you, perhaps. To me it seems completely illogical. It
would make far more sense to add a date option to cat(1), which
already has a line-numbering option.

3 in fact ;) and the code is not that much tested yet so we might see more.

I personally see this 3 possible ways:
1) leave it as it is (ie. as what will be commited shortly), this means runtime
checking for osrelease sysctl and behaving according to it
2) introduce option LINUX_24 or something like that to make this a compile time build
3) remove the 2.4 completely saying that "if you want 2.4 emulation downgrade fbsd as well".
notice that this is 100% ok because linux itself doesnt support 2.4 emulation on 2.6 kernel.
I would go with number 3.

I think that would be a great selling point.. especially if two

Hmm,
I'm still completely amazed that you had expected anything else but a
bikeshed by discussing it on a mailing list. :)

These programs do not work on my system either. Same setup as Intron's.
I don't even get the Adobe Logo. Someone mentioned before that the
offending file was known, but that how it was offending wasn't known. I
assume there has been no progress on that. Glad to help if I can.

Actually you shouldn't need runtime checking so much as load-time reading of the elf
headers.
Let me say that there is something amazing about FreeBSD:
the ability to build a kernel with COMPAT_XX and run old FreeBSD binaries
In some ways this seems like a page straight out of POLA.
Linux can be a major pain; even in a maintained distribution ala Redhat the system
seems to EOL in the blink of an eye. I had a customer once who had a mix of old
binaries and obscure requirements (e.g. pm3). I put together a vmware image of the
necessary environment: just the right kernel, just right version of glibc, etc.
Most of the stuff that gets run through linux emulation on FreeBSD is for desktops
and isn't mission critical... still I'd get pretty annoyed to one day discover that
I needed to buy new versions of Matlab and Mathematica...
On the other hand developer resources are scarce; it would be much better if I had
FreeBSD binaries of those programs :o)
The linux model works when:
1) you have the source for everything
2) all the source is actively maintained to keep abreast of API changes
3) you are free to recompile and replace any part of the system at a whim
Or you can run Debian and wait for three year cycles :o)
(okay,okay, I'll stop picking a fight now;
hope everyone takes a little ribbing in good fun)

is it the case that EVERY TIME you see this the program which emits this doesnt work?
are there any other non-working programs that doesnt emit this?
how you can help: if you can see any futex usage pattern that causes problems please tell me.
or if oyu have some simple testing program which reproduces this behaviour.

this is not hard to implement but remeber that it causes getpid() to be
quite expensive function. and as netchild said - newer glibc doesnt work with
2.4 kernel so unless somone is willing to maintain libc for the old linux_base
there wont be any use for this.

FWIW I am also against, in a non-vehement way. My reasons are:
1. I don't like to encourage the writing of non-portable scripts, which will
run on FreeBSD but not Linux, any other *BSD or indeed any other Unix in
existence. Linux scripts which start #!/bin/sh but use bash-isms are
particularly annoying... scripts which rely on non-standard additions to
core utilities are also a pain.
(I'm not a POSIXLY_CORRECT extremist though. I apply my own woolly
definition of 'standard' here)
2. I object to feature bloat, not especially because it makes the core
utilities and their manpages larger (we're only talking a few bytes in this
particular case), but because it makes finding the right command and the
right flag more difficult.
Suppose you came along to a system knowing that there was a command
somewhere to add timestamps to log streams, but couldn't remember what it
was. I personally would never guess that it was "date" (*). 'man -k'
wouldn't be able to find it, because this hidden feature is unlikely to make
it into the one-line description.
3. One command doing many different things seems to go against the Unix
philosophy of simple utilities doing one thing each.
>From the point of view of (2) and (3), I'd rather than there was a
completely separate utility for adding timestamps to streams, even if it
shares 90% of its code with 'date'.
4. The other thing I'm uncomfortable with is that this modification to date
does handles one specific type of timestamp addition - adding a timestamp to
the start of a line, where lines are terminated by \n. Whilst this is a
common case, it's certainly not the only case where I've wanted to add
timestamps. That makes it feel like a special-case frig.
Regards,
Brian.
(*) The nearest similar standard Unix command I can think of is nl(1)

After thinking about this awhile, I'd say that I'm mildly
against it. The `date' command has never been a filter,
and I don't see any reason that this feature needs to be
in the `date' command as opposed to some other command.
>It's just that the ney sayers always scream loudest.
I'm certainly not screaming. But if we were to add this
option somewhere, then des's suggestion of:
It would make far more sense to add a date option
to cat(1), which already has a line-numbering option.
does seem very reasonable to me. `cat' already has
several options which cause data to be filtered as it
is copied. The only trick is that you also want to
specify the format to use for the timestamp. So, just
have the new parameter require a strftime() string:
cat -D "%Y-%m%d-%H%M: "
And maybe include a reference to the `cat' command in
the man page for the `date' command, just so people
realize that the option is available.

Hi,
my laptop has just triggered a bug in the iwi(4) driver. I called
doadump() from DDB prompt and was happily surprised to see that
only 167 MB of memory where dumped, instead of 1 GB.
Unfortunately once I have rebooted, I went into kgdb and asked
for the backtrace, which look pretty accurate until it reached
the iwi(4) functions, which was loaded from multiuser mode.
I know this is iwi(4) because I saw the backtrace in DDB.
Is it the desired behaviour, not yet implemented, or am I only
missing something ?
Thank you for your help.
Regards,

Would it be possible to maintain 2 sets? Basically, leave the old stuff
avalible, but require some sysctl or compile-time setting to use it... if
no one steps up to maintain it, let it rot. If someone wants to deal with
it... let 'em!

1. The kernel message "second wakeup" is produced when Firefox 1.5.0.6
is normally working.
2. With the help of top(1), I've known that both Mozilla 1.7.12
(GTK 1) and Firefox 1.0.7 (GTK 2) are stalled on the state "linuxf".
3. Adobe Reader 7.0.8 can work occasionally if its configuration files
(in ~/.adobe/) are initialized for the first time with the help of
Roman's patch.
Well, I would do some hacking to find the problem.

Yeah, you have to do some magic to debug KLDs. Basically, you have to
figure out where they were loaded by walking the module list, and then
tell GDB where to find the TEXT section using add-symbol-file.
Instructions for this are available at
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-kld.html
Good luck :)

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I thought I'd investigate spend some on what seems to be becoming the
standard for new laptops. However, before I spend nonsensical amounts of
time on the items below, I'd appreciate an indication as to what
progress has been made - perhaps I can help test something rather than
re-invent the wheel?
The "pain-points" for FreeBSD users appear to be, in my own order of
priority, as follows:
1) Intel Wireless 3945ABG
I've seen the work by Damien Bergamini on an OpenBSD driver but I'm
beginning to think that the iwi driver is a better starting point.
The sticking point with the only other driver I know of (for Linux) is
Intel's choice to implement a binary module (actually a daemon) to
enforce compliance within regulatory domains. Not that this bad, just
that it imparts a level of complexity to the objective.
2) Intel 82801G (ICH7 Family) HDA
I have the HDA device itself probed but the Realtek ALC861GR in my
Toshiba needs (significant?) work before I can call it functional.
3) Intel 945GM/GMS/940GML Graphics
The xorg server can be made to work at 1280x800 with a patch but AGP
support looks like it needs patches to sys/pci/agp_intel and agp_i810. I
haven't looked at DRM as yet.
Please contact me off-list if you have some constructive suggestions,
Thanks,
Michael

In theory, yes. Judging by the comments on the implementation, a
more efficient approach should probably be implemented if the decision
is made to maintain multiple linuxulators.

IMHO, it is cleaner to explicitly delete it once it becomes non-functional.
Having dead code lying around just slows down compilation and misleads
people into thinking that it is functional. If someone wants to resurrect
it at a later date, they can always retrieve it from the Attic.

what makes 2.6 and 2.4 incompatible is the way they treat "pid". in 2.4 times
pid is something unique to a process, ie. you cannot have two processes with the
same pid. in 2.6 this changed pid is number processes can share and now tid is
used as "unique identifier of a process".
netchild commited patch which lets this happen and it makes getpid/getppid/exit_group
quite expensive (I have to retrieve osrelease for a given jail and compare the string).

Don't think about the kernel part. There are multiple ways of handling =20
it. You could even move the 2.4 code to "linux24" and brandelf only =20
some apps with "Linux24" instead of "Linux". This way you don't need =20
to check every time and you don't need to do a sysctl for the apps in =20
question. The kernel is the easy part. The hard part is the userland =20
stuff. As one of two active people which take care of the linux =20
userland infrastructure in ports I can tell you that we just have the =20
official man power to maintain one linux_base infrastructure. And this =20
doesn't take into account that old linux_base ports which still work =20
with 2.4 but will go away in the future and that the linux =20
distributors don't fix security bugs in old releases (so we have to =20
move on to newer linux binaries and remove the old ones). The =20
person(s) taking care about the linux24 stuff would have to create =20
binary packages with fixes for this himself.
Bye,
Alexander.

BTW, has anyone contemplated or even done this - some sort of a script
to automatically add all modules that were loaded at a time of crash ?

Sounds like a good idea. I will write one. Sounds like a candidate for

There's another possibility, which doesn't require a new
option letter at all. You could add a new escape sequence
to the format string, e.g. "%*". Whenever date(1) is
called with a format string containing that sequence, it
goes into filter mode and replaces the sequence with the
current line. That would also enable you to be more
flexible with the placement of the timestamps.
For example:
$ printf 'foo\nbar\nbaz\n' | date +'%H:%M:%S %*'
16:39:58 foo
16:39:58 bar
16:39:58 baz
Best regards
Oliver
PS: Personally I would recommend installing gnu-awk (it
was formerly part of the FreeBSD base system, but it was
replaced by a crippled awk, unfortunately), instead of
hacking date. I always install gnu-awk because it's so
useful.
$ printf 'foo\nbar\nbaz\n' | gawk '{print strftime("%T"), $0}'
16:41:06 foo
16:41:06 bar
16:41:06 baz

Hi,
The parsing of entries in /etc/fstab seems to be broken. In particular, in the
case of NFS, mount options (tcp) seem to be ignored. Matt J. reported that
the "ro" option in fstab was bring ignored.
This is on a releng 6 base about 6 weeks old.
I vaguely remember there being changes in this area recently. Has anyone else
seen this ? Has this been fixed recently ?
thanks
mohan

Hmm, isn't this the task for asf(8). If not, what is asf(8) for?

This is a very nice command, thank you!
But it does not seem to be directly applicable to postmortem situation
i.e. crash dump debugging.
Or maybe it will be easier to teach kldstat to work with dumps/images in
addition to what it does now ?

look at src/tools/debugscripts which has two different solutions to the
problem...

I have been bitten by the bigger sector size + kernel crash, and it is
not funny. Could you *please* add a note to the geli and/or gjournal
manpages describing the various possibilities and their
advantages/drawbacks? Thanks.

Hi all,
Here is a recipe how to panic CURRENT's GENERIC kernel from the
command line:
(enter single-user mode)
# mount -r /usr
# mount -r /usr
# umount /usr
# cat
[panic!]
As shown below, the panic happens in GEOM when /bin/sh searches
$PATH for cat(1). The recipe works in 6-STABLE, too. Is anybody
interested? Thanks!

This has been reported a number of times before, apparently it's
difficult to solve.

No, it's difficult to solve in a architectural clean way, but IMHO this
bug should be fixed. I've a fix for this (which allows for multiple
read-only mounts). It's hackish, but works.
Unfortunately phk@ didn't agree on committing it, so next time, please
CC him:)

That's a bit drastic. Wouldn't be more sensible to encourage someone to
add the same feature to our BSD-variety awk?

FreeBSD's awk is the One True Awk. See its history. If you
can convince the K in awk to add the feature, then it will
be added to FreeBSD.

Just to satisfy my curiosity: Do you have references to a discussion
of the problem? When such a simple script triggers an architectural
issue, the latter is definitely worth taking a glance at. :-)
Thanks!

I apologize, my words were probably a bit harsh. I'm
very sorry for that.
I agree that it would be useful to add strftime() to
our version of awk. I would be willing to implement
it myself and send-pr a patch (i.e.: yes, I volunteer),
but only if such a feature would be accepted and
commited. I wouldn't like to spend time on a patch
and then be refused because it's just regarded as
bloat ...
Best regards
Oliver

What about the SoC 2005 project, aiming to push libalias down
into a kernel module ? IIRC, there have been some patches
but I saw nothing commited. This thread has stirred this
up from my memory.
Thank you,

Paolo Pisati is now a committer and hopefully will commit
that stuff when he will be done with his current SoC work

Hi all,
I have a disk which has just developed a bad sector in the middle of
swap space. I'm seeing occasional:
swap_pager: I/O error - pagein failed; blkno 38626,size 32768, error 5
errors in the logs, and whichever application happens to have a page
there is killed. The 'blkno' value is always the same.
I realise that I need to replace the disk. However, while I'm waiting
until I can schedule the downtime, is there a short term solution I can
use to stop FreeBSD (I'm running current from a couple of months ago)
from trying to use this block?

I noticed this a few weeks ago... I figured that since the packages were
built for STABLE that COMPAT_43 was biting me again (The removal of
COMPAT_43 caused a lot of 6-packages to segfault on my current machine).
I compiled from ports those apps that I couldn't get a CURRENT package
for; that fixed the segfaults, and since I never really use java I just
removed it (as the port has been updated to grab the foundations
package). If you need java you could probably still build it from source
by grabbing the source / binary downloads from sun and patching /
compiling yourself. (I'll wait until the packages are updated.)

Now I added COMPAT_43 to my kernel but java still segfaults.
