On the firewall device I was thinking of experimenting with, I do have long TCP sessions that it sounds like HZ=2500 would break.

System Crash(bundirty) on 5.2.1
Hi all. First, sorry for my bad english =) Well, on the past(28/03/2003 on FreeBSD 5.1-Release), i'm read about the nfs bug, and now, i'm got the same error on my fbsd box, and on history of all freebsd lists i've found the same response: no fix for this bug. On my server the error appears, only before to mount my nfs home and mailspool dir into my server, and (the interessing point) when i run any ftp server, the server go down, with the error: panic: bundirty: buffer 0xe28a198f About the box: My server is a FreeBSD 5.2.1-RELEASE, running apache+php, mysql4.0, openwebmail 2.30, proftpd 1.2.9(tried to use the internal ftp, but doesn't solve the problem), mounting two nfs volumes: /data and /var/mail /data: openwebmail users directory on other server, not my MTA box I'm using NIS to auth the users on all systems. The question: Can functions like, getpw* cause this problem? running only apache, mysql, openwebmail, the system dont crash, but before start any ftp server and anyone make upload of files the system stop with the error described above.

Recovering from RELENG_5_1 - RELENG_5.2 world/kernel statfs fubar?
[ nb. There's a question at the bottom. The rest is for context and the archives, since I couldn't find this kind of detail there. ] System running RELENG_5_1 (5.1-p12, IIRC) built RELENG_5_2 and started installworld before installkernel in flagrant violation of the correct method and dire warnings of 20031112 in UPDATING. The installworld borked early on during an mtree process and for reasons I can't quite determine the output which should have eneded up in a file didn't. From the datestamps, most or much of /bin and /usr got updated. Booting the old (5.1) kernel made it almost to single user, but /bin/sh wouldn't play. With the help of CD 2 from my 5.1 set I put the new kernel in place and booted it, expecting the worst, however almost everything runs fine - desktop, tools, apps and even the not-yet-installed linux.ko. The problems I still have that /usr/bin/make was the old one, so there was no simple installkernel/world option to fix things. # /usr/bin/make Bad system call (core dumped) I replaced /usr/bin/make with /usr/obj/home/src/usr.bin/make/make and after being much confused relaced /usr/obj/home/src/make.i386/make too since this one appears to be used instead of /usr/bin/make - part of the bootstrap, presumably. With make appearing to work, a make installkernel KERNCONF=MYKERNEL bombed on the first install. Unlike make, /usr/bin/install seems to run ok, despite being the old 5.1 version and doesn't core: # /usr/bin/install -v usage: install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode] ... After a bit of digging in /usr/obj and /usr/src, it looks like usr.bin/install has been replaced with usr.bin/xinstall, which gets installed as /usr/bin/install. Replacing /usr/bin/install with /usr/obj/home/src/i386/home/src/usr.bin/xinstall/xinstall made no difference and althugh this new /usr/bin/install seems to run ok, the installkernel still bombed with a signal 12: # make installkernel KERNCONF=MYKERNEL ... mkdir -p /boot/kernel install -p -m 555 -o root -g wheel kernel /boot/kernel *** Signal 12 This looks like it's doing the same kind of bootstrap jiggery-pokery, but I can't find another install after digging deep with find and make debugging output. Since install is static, it's not a so problem. Other seemingly broken bits I've found so far include logging through syslog (which is running), sockstat -4, csh (which I don't use and know is tcsh and is a contrib, but I can't find any sign of anything resenbing a csh binary in /usr/obj). How can I dig myself out of this hole so I can installkernel and installworld with my shiney new 5.2.1 build? I'm sure I've glossed over or missed much critial information, so please let me know whatis relevant and needed. For starteds, here are lists of all files in /bin, /lib, /usr/bin, /usr/lib and /sbin installed during the last installworld[1]. and all files not installed during the recent aborted installworld[2].

Download fixit CDs or floppy images for 5.2+ or from snapshots.jp.freebsd.org and install the included kernel on your hard drive by hand. It will work with your halfway installed world. Use that to install the correct kernel. Reboot with that kernel and finish following the instructions in UPDATING.

Looking for static analysis tool to generate call graphs
I'd like to generate static call graphs from sections of src/sys/kern, src/sys/net, and src/sys/netinet, and ideally, get an output that looks pretty when printed to a (perhaps large) piece of paper. It doesn't need to be able to handle function pointer magic in structures (vnode operations, socket operations, file descriptor operations, sysinits, etc); I just want a fairly high-level graph to get a feel for particular chunks of code spanning a couple of C files.
