(Just in case) I didn't intend to say create/destroy is the wrong approach and pim6sd doesn't need a fix. My point is that create/destroy is a big change that can affect many applications (including pim6sd) and that a "workaround" is not to use the operation for now.

The code has undergone some minimal testing using the new test suite, but it has not been tested in real life. As an additional bonus, the layout of the code now matches with that of the source tree. This enables the code to be merged to the source tree once the maintainers think that the code is mature enough. The code compiles both under 4.7-STABLE and 5.0-RELEASE, but SMP compliance has not been completed.

This has been done for NetBSD. It is a required component if one wishes to natively support ISO based protocols such as IS-IS. I ask because a few networks, including mine, use FreeBSD systems for monitoring. Since we are an IS-IS shop, I am hoping someone has worked on moving the ISO code into FreeBSD so we will not be required to move our network monitoring systems over to NetBSD or some version of Linux.

Does your patch use the AF_ISO sockets on NetBSD or does it still use the BPF ? Moreover, you can post your patches on the Zebra's and ISISd's mailing list, maybe some Zebra's users would tell you more about it.

You can take a look at it via cvsweb. This is substantially incorrect. The code was working fine, until FreeBSD's routing code was changed out from under it, without the person who did the changing maintaining all the other FreeBSD code that touched it, at the same time (ISODE was an integrated component of BSD at the time, but it's routing code was not changed at the same time by the person making the changes elsewhere in the source tree). The change annoyed the piss out of everyone who was using X.25 over packet radio, which also died on the table in the change. Three local amatuer radio gateway systems switched over to using Linux over it, and several of us who had advocated FreeBSD to the club were not at all happy about it (but were unable to do anything, since the new code was too poorly documented at the time).

I'm trying to make it easier to use NFS from my desktop with amd. Using the vanilla /etc/amd.map (tried changing vers to 2) and only modifying one of the arguments to amd from the default provided by /etc/defaults/rc.conf, I have the amd running as: amd -a /var/run/.amd -l syslog /host /etc/amd.map /net /etc/amd.map (the default -a's argument -- /.amd_mnt is not good for me, since / is mounted read-only). The amd works, but there are very long delays -- 30 to 90 seconds -- each time I do, say ls -ld /net/attila/ While doing this, I ran tcpdump, in two windows -- for each of the interfaces -- but merged the output here for your convenience (MYMACHINE replaces the real hostnames): 13:45:52.972586 localhost.852 > localhost.1023: udp 104 13:45:53.974953 localhost.852 > localhost.1023: udp 104 13:45:55.984956 localhost.852 > localhost.1023: udp 104 13:46:00.014985 localhost.852 > localhost.1023: udp 104 13:46:01.435114 MYMACHINE.3523280896 > attila.nfs: 40 null 13:46:01.435422 attila.nfs > MYMACHINE.3523280896: reply ok 24 null (DF) 13:46:01.435705 MYMACHINE.1022 > attila.sunrpc: udp 144 13:46:01.436335 attila.sunrpc > MYMACHINE.1022: udp 28 (DF) 13:46:08.075112 localhost.852 > localhost.1023: udp 104 13:46:24.125396 localhost.852 > localhost.1023: udp 104 13:46:24.126120 localhost.1023 > localhost.852: udp 96 13:46:24.126217 localhost.852 > localhost.1023: udp 104 13:46:24.126295 localhost.1023 > localhost.852: udp 96 13:46:24.126344 localhost.852 > localhost.1023: udp 104 13:46:24.126410 localhost.1023 > localhost.852: udp 96 13:46:24.127416 localhost.852 > localhost.1023: udp 104 13:46:24.127525 localhost.1023 > localhost.852: udp 96 13:46:24.127578 localhost.852 > localhost.1023: udp 104 13:46:24.127651 localhost.1023 > localhost.852: udp 96 13:46:24.127699 localhost.852 > localhost.1023: udp 104 13:46:24.127765 localhost.1023 > localhost.852: udp 96 Although _all_ of the amd's log messages are directed into the special /var/log/amd.log here, the only things it said in the above three minutes was: Feb 19 13:46:01 MYMACHINE amd[4012]: recompute_portmap: NFS version 2 Feb 19 13:46:01 MYMACHINE amd[4012]: Using MOUNT version: 1 Does this make sense to anyone?

I have several questions and since I have very little kernel programming experience I would appreciate any input that the more experienced folks are willing to offer. My goal with this code is to get it accepted into the FreeBSD tree. So any advice or critque of implementation or style is actively solicited. The Linux implementation exposes the KIS variables through the /proc filesystem. I have chosen to use the sysctl interface for my initial implementation. So far this is working out well, I am reading 4 variables about each connection via sysctl. Is sysctl the right way to get this information? We may poll some of these variables on a second or sub second interval. In order to tune a TCP connection it will be necessary to write to some of the sysctl OIDs. AFAIK only root can write to sysctl. I can see two alternatives to solving this problem: 1) using a proxy daemon which runs as root to handle the updates or 2) add a permissions system to sysctl. Option 2 seems like quite a lot of work and I'm not certain it is generally useful. Any thoughts? We are interested in receiving asychronous notification of events within a particular TCP session in userland. I am planning to use the kqueue mechanism to provide this. Patches relative to 5.0-RELEASE are available at: http://rivendell.ncsa.uiuc.edu/~jdugan/web100bsd/ In truth there isn't much to the patches yet, but it demonstrates the direction I have taken thus far. 1. Some background Web100: The Web100 project is concerned with improving TCP performance for typical TCP sessions. As we all know getting TCP to perform well over long, fat pipes tends to require quite a bit of tuning. Web100 is an effort to automatically tune TCP connections. To that end Web100 has developed a TCP Extended Statistic MIB to define what instruments in a TCP stack are useful for understanding the behavior of TCP sessions. The KIS is the implementation of this MIB for a particular TCP implementation, currently the only fully developed KIS is for Linux. With the information exposed via the KIS the TCP session can be automatically tuned by a user space process. Information gleaned from the KIS is also useful to diagnosing many common problems with TCP performance. The Web100 website has further information, including the code for the Linux implmentation and an IETF draft of the TCP Extended Statistic MIB. http://www.web100.org/ Jon -- Jon Dugan | Senior Network Engineer, NCSA Network Research jdugan@ncsa.uiuc.edu | 269 CAB, 605 E Springfield, Champaign, IL 61820 217-244-7715 | http://www.ncsa.uiuc.edu/~jdugan/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Wed Feb 19 14:20:57 2003 Delivered-To: freebsd-net@freebsd.org Received: by hub.freebsd.org (Postfix, from userid 931) id 8C44937B401; Wed, 19 Feb 2003 14:20:55 -0800 (PST) Date: Wed, 19 Feb 2003 16:20:55 -0600 From: Juli Mallett To: Petri Helenius Cc: Garrett Wollman , "Joseph T.

Any company which is going to have to modify an operating system to run on their routers who ignores an operating system with a reputable network stack merely because it lacks in-tree support for a particular protocol isn't worth hte money. There are plenty of good ones out there who, in addition to maintaining large amounts of local support diffs for FreeBSD, also maintain netccitt or netiso or netns or whatever suits the market they're selling for. Hell, if they turn it down simply for lack of a network stack, then they probably simply aren't willing to do anything but minor maintainence to "keep it running" so what's the point for us? They're probably making at least a few of their sales for having it around. Heck, there are probably more people attached to FreeBSD on pc98 than to netiso or .... I'm willing to say that because hey look it's been at least moderately well maintained, and kept up with most moves forward, except for the wd(4) stuff, though I think I heard someone talking about hiding wd, simply to get people to actually find and fix the bugs in ad on pc98.

I am afraid it is not that simple. By using as much existing work as a company can get its hands on (either open source or bought from s/w vendors) it can get its product to market that much sooner. This allows a company to focus on code integration, bug fixes and most importantly, on the value being added by its product. All else being equal it would a waste of time & resources (from the company's perspective) to reintegrate netiso in FreeBSD when it is already available in NetBSD. Of course, it should also look at code quality, ease of maintenance, scalability etc. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Wed Feb 19 15: 0:12 2003 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 8AAC637B411 for ; Wed, 19 Feb 2003 15:00:09 -0800 (PST) Received: from monet.titania.net (enter.titania.net [192.133.102.254]) by mx1.FreeBSD.org (Postfix) with ESMTP id B394643FA3 for ; Wed, 19 Feb 2003 15:00:07 -0800 (PST) (envelope-from jtk@titania.net) Received: from titania.net (morisot.titania.net [192.133.102.10]) (authenticated bits=0) by monet.titania.net (8.12.6/8.12.6) with ESMTP id h1JN1oYZ017533 (version=TLSv1/SSLv3 cipher=DES-CBC3-SHA bits=168 verify=NO); Wed, 19 Feb 2003 23:01:51 GMT (envelope-from jtk@titania.net) Date: Wed, 19 Feb 2003 17:00:08 -0600 Subject: Re: support of iso networking Content-Type: text/plain; charset=US-ASCII; format=flowed Mime-Version: 1.0 (Apple Message framework v551) Cc: freebsd-net@FreeBSD.ORG To: Garrett Wollman From: "Joseph T.

I have been trying to understand the locking strategy in the TCP portions of the code. I have primarily been looking at tcp_input.c. It seems like several variables are locked for the vast majority of the time in tcp_input(). (In particular tcbinfo and inp). This was problematic when I called a function to update some stats when a TCP session entered the ESTABLISHED state because witness kept telling me that the we might sleep with tcpinfo and inp locked. Can someone briefly explain the strategy here? Or maybe there is a document somewhere that would be helpful? (I looked but didn't find anything.) I have very little experience with locking and multithreaded programming, so that may be the root of my confusion. As a result I want to make sure as I go forward with the Web100 code that I lock it appropriately.

Klein a écrit : > So how great a delta exists between NetBSD and FreeBSD? > Can't the NetBSD code be used as a starting point? I have been looking on this delta. I had been stuck on the handlers of the "user requests" ( xxx_usrreq() ) that are deeply different between NetBSD and FreeBSD. Moreover the TCP/IP Illustrated book illustrates only the 4.4BSD API. I could not find documentation about the patch that was introduced in 1997 into FreeBSD. The lonly information about this patch that I have found is: "1) Old-style (pr_usrreq()) protocols are no longer supported, the compatibility glue for them is deleted, and the kernel will panic on boot if any are compiled in." Are there any papers or slides that describe the new design of the handlers of the user requests on FreeSBD ? If one day I will continue on Netiso, then according to me, a first step is to get it work on FreeBSD 4, then the SMP support for FreeBSD 5 could be evaluated. If both are done on the same time, it would be too difficult. Same thing for X25... Maybe this code could be tested with the ISIS routing support of gated 3.5.11. I think it was using the AF_ISO sockets. I have googled in order to find the gated 3.5.11's source code, however I could not catch it !!! I have only found the INRIA's patch.

The old pr_usrreq routine used to be a big switch statement on the second parameter, the request type. Now, each case is a separate function with its own pointer in struct pr_usrreqs.

I have an ftp server that became sporadically inaccessable over the network. I did some poking around and found that there were about 8k TCP connections that were in the state "LAST_ACK". The limit for maxsockets is about 8k for this machine so the reason that new connections were failing was because the boundary for sockets had been reached. I graph the number of open files and sockets using MRTG and saw that for the last few weeks the number of open sockets had been gradually rising due to connections "stuck" in LAST_ACK, a clearly unstable condition. This is a 4.5p24 machine. I also checked another ftp server that is 4.6.2 and it exhibits the same behavour though the limit on maxsockets is not reached yet. I checked a mail server running 4.5p24 and it too has about 4k connections "stuck" in LAST_ACK. I have verified their presence for at least 1 day. The archives indicate that this has been a problem but was fixed in 4.5. So I was wondering if this problem is still in post 4.5 systems and upgrading to 4.8 will fix it or whether there is further investigation needed to solve this issue. Or what can I do to determine the problem or help someone if it is a kernel problem. # netstat -an|grep LAST|tail tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.2676 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 67.35.48.182.2886 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.1758 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.1757 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.1690 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.1322 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 128.175.154.185.1065 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 209.37.184.2.37067 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 209.37.184.2.30984 LAST_ACK tcp4 0 0 66.xx.xx.xx.20 209.37.184.2.30865 LAST_ACK thanx - steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Feb 21 12:22:51 2003 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 50CE137B401 for ; Fri, 21 Feb 2003 12:22:50 -0800 (PST) Received: from spitfire.velocet.net (spitfire.velocet.net [216.138.223.227]) by mx1.FreeBSD.org (Postfix) with ESMTP id E31BA43F85 for ; Fri, 21 Feb 2003 12:22:49 -0800 (PST) (envelope-from steve@nomad.tor.lets.net) Received: from nomad.tor.lets.net (H74.C220.tor.velocet.net [216.138.220.74]) by spitfire.velocet.net (Postfix) with SMTP id 17A9B4B7D95 for ; Fri, 21 Feb 2003 15:22:48 -0500 (EST) Received: (qmail 9398 invoked by uid 1001); 21 Feb 2003 20:17:01 -0000 Date: Fri, 21 Feb 2003 15:17:01 -0500 From: Steve Shorter To: freebsd-net@freebsd.org Subject: Re: TCP stuck in LAST_ACK in 4.5 and 4.6??

However, what I can share with you is this snippet of a conversation about the problem I had back in October: --- From: G.P. de Boer To: Mike Silbersack Subject: The "stale TCP-connects in LAST_ACK" problem Hi Mike, I've upgraded my system to 4.7-STABLE as you said, to see if the patches Matt Dillon MFC'ed made my problem disappear. I have good news: with a current uptime of more than 4 days I have no single stale connection in the LAST_ACK state. On 4.6.2 I have seen a number of stale connections starting from about 3 days of uptime; From this I conclude (a vulcan would kill me for such reasoning though) it's fixed. --- So, I would suggest that you update to 4.7-stable. If that's not an option, I can look back and see if I can figure out which patches in question I was referring to at the time. Sorry that I can't give you a more concrete answer. Dillon's changes weren't meant to fix the LAST_ACK problem, but they ended up doing so for G.P. de Boer. I would be very interested in hearing if they have the same effect for you.

Note that PSH flags are always ACK'd immediately, whereas non-PSH flags are subject to delayed ACKs. Are you perhaps measuring the occurance of that?

I'm having problems talking between a FreeBSD -current box with a wi(4) card (LinkSys I believe - it's a remote box) and a Belkin access point (also a LinkSys WAP11, but I haven't performed the same measurements). For naming conventions, box1 will be a FreeBSD box with the wireless card. Box2 will be a FreeBSD box with an ethernet interface on the LAN side of the access point. If I do the following: time dd bs=1 if=11mb | ssh -c none box2 dd of=/dev/null That is, transfer an 11 Mb file of random data from box1 to box2, it happens pretty quickly. A bit under 1Mb/s, which is fine. However, when I do the same in reverse, from box2 to box1, the transfer halts at 147456 bytes. The output block size of the first dd doesn't have any effect. The default 512 bytes per block, 1024 and even 1 byte per block all stop transmitting at 147456 bytes. Does anyone know what is magical about 147456?

I had the same problem on one machine doing some regular batch ftp transfers. It occurred when running versions 4.6.2-RELEASE and 4.7-RELEASE. Since I updated to 4.7-STABLE after the patch was committed I never had any problems with LAST_ACK. My advise: update to 4.7-STABLE or wait for 4.8-RELEASE (don't know when it's out, shouldn't be too far away).
