pf route-to doesn't work for me after upgrading to 4.6
Hi, did anything change in regard to pf rules with the route-to option in recent versions of OpenBSD? I've just reinstalled an old system that was running OpenBSD 3.9 with 4.6, and gave it my old pf rulesets. There is a rule that is supposed to send all traffic originating from a certain local network into a tunnel instead of to the default gateway. Which it did with 3.9. Now it seems to do nothing - outgoing traffic just follows the default route, regardless of the route-to rule. It was basically something like this: pass in quick on $int_if route-to $vpn_if from $special_net \ to ! localnets keep state (The relevant traffic comes in through $vpn_if by itself.) Also tried binding the rule on the external interface, and using the route-to syntax with gateway address, but that didn't work either. Alex.

ASN Flow Exporter for OpenBGP device
Hello, I have an OpenBGP device and I need to find out which ASN demands more bandwidth to do some sort of traffic policy engineering. Therefore I need to know if there is any software that is able to export netflow data including SRC/DST AS on an OpenBGP system. I have used pfflow and softflowd but on the second AS is always '0' and pfflow will depend on the ability to have pf data per ASN. I know I can set up some rtlabel or pftable to allow OBGP interaction with PF. However, I would need to manually set the whole scenario and the reliability of my information would depend on my observation of potential ASN to be tracked. Its OK but this way I miss the behavior deviations, if a certain quiet ASN suddenly raises traffic and later lowers it back again. So, how options we have? Thank you in advance. -- === Eduardo Meyer pessoal: dudu.me...@gmail.com profissional: ddm.farmac...@saude.gov.br

I'll let you know what it does for me. Of course, this is REALLY increasing the file handles to a ludicrous level too, and probably isn't necessary, but at this point, I just want to see what works. -John Hi John. I'm running squid with ufs. I can make this test on a vm. But this test is necessary? I say this because I've tried to run squidclamav without squid, then only two processes, squidclamav and squidGuard called by squidclamav...no operation, not redirect from squid...nothing..only runned by the shell. It dies in the same mode... the problem is not openBSD Kernel but squidclamav for me...and how we can see, squidclamav is not in openbsd package mirror dir and in a OpenBSD ports directory. In the next days I will try to recompile the kernel with new option, try not harm. But there is another way: using squid + squidclamav to filter viruses (if squidclamav doesn't crash, I'll make a test for this), and use squidguard domain blacklists in an acl to get content filtering. It's possibile that openbsd kill squidguard because squidclamav make a strange operation not allowed? Or maybe this is a bug also for Linux environment...I can try also with Linux (always on vm) too see if it has the same behaviour. Maybe we do have different problems then, because I now don't even have squid alone stable. It takes days to crash though. For me, squid and squidclamav and squidguard all crash with the same two errors, one related to file handles and the other related to message queues, but the latter is only because I'm using diskd instead of straight ufs. I think my problem is kernel related. And yes, it all runs flawlessly on Linux. Very strange. -John Hi john! I've make the test with: maxusers 1024 option MSGMAX=16384 # (max characters in a message) option MSGMNI=4096 # (# of message queues) option MSGMNB=32768 # (max characters in a message queue) option MSGTQL=2048 # #max # of messages in system) option MSGSSZ=64 # (size of a message segment) option MSGSEG=4096 # (# of message segments in system) ...and try setting kern.maxfiles=32768 ...and in login.conf openfiles-cur to 16384 but the result is the same...squidGuard dies.

Re: asynchronous I/O
On Fri, Dec 4, 2009 at 4:45 PM, Todd T. Fries t...@fries.net wrote: Does aio really require threading? In some sense, yes, in others, no. aio is designed so you don't need (userland) threads. Normally you'd write your server to use non-blocking io. But that doesn't work with files on disk. How can it? With network sockets, you have somebody on the other end pushing data into your pipe which the kernel buffers. But the file system isn't going to read stuff from disk until you ask for it, there's no somebody else pushing data at you. That's what aio is for. It starts up a disk request without waiting for it. Then you can come back and get the result. Think of it as preemptive polling. Instead of calling select()/poll() to find out what's _ready_ for io, you call aio and then later it tells you what's _done_ with io. A normal implementation would be purely kernel based, with a few new syscalls. But the kernel would still need to keep track of all the buffers and io requests. So at that level, there's still something resembling threading. This is all fairly easy to fake in userland. When somebody calls aio_read(), just spin up a thread that calls read() until done. The main process goes on with its work, magic happens in the background. Of course, this requires the ability for one thread to execute while another is blocked, which the uthreads implementation we have doesn't have.

(For example, the laptop on which I'm typing this has #1 = 4.6-stable and #2 = 4.4-stable.) A couple of important notes if you decide to try this: First, the standard OpenBSD install hard-codes a as the root partition. So... at the (I)nstall, (U)pgrade or (S)hell? prompt, type s to get a shell, then # ed install.sub $-1(go to the 2nd-to-last-line) s/a/d/ (change the 'a' to a 'd') w (write the memory buffer back to the file) q (quit the ed editor) (maybe follow with 'more install.sub' to confirm that all went well) OpenBSD will how happily install with root on the wd0d partition. [An alternative is to install what you want to wind up in #2 to the #1 partitions, use dump|restore or tar|tar to copy these to the #2 partitions (as per FAQ 10.2), run installboot(8) to fixup booting to the #2 partitions, then reinstall what you really want to #1.] Finally, and most important of all, *don't* try this unless you know what you're doing! Playing around with partitions this way works fine if you do things correctly, but mistakes can easily scramble your disk (more accurately, the data on it). In particular, don't try this until you grok the FMs disklabel(8), fstab(5), installboot(8). And have a full backup *before* you try it... -- -- Jonathan Thornburg [remove -animal to reply] jth...@astro.indiana-zebra.edu Dept of Astronomy, Indiana University, Bloomington, Indiana, USA If the triangles made a god, it would have three sides. -- Voltaire I believe Josh Grosse has the right idea - if your system supports booting of USB drives, $5 will buy a 1gb stick that is more than adequate for running OpenBSD on. OK, I get it. I thought root always had to be 'a'. But being able to use the same disklabel for both installations is even better than using two separate disklabels. Thanks for the hints and tips!

CPUID support on top
Not sure if useful to anyone else, but here it goes a patch that adds a new column to top, showing the last CPUID where a process has been seen. Other top implementations have this feature, which can be useful on some situations. Solution may not be very elegant, but it was the one which required less code churn. I may work on other solution if there is interest on having this merged. diff -u -r1.64 machine.c --- machine.c 28 Apr 2009 21:24:41 - 1.64 +++ machine.c 4 Dec 2009 22:53:39 - @@ -69,13 +69,13 @@ * These definitions control the format of the per-process area */ static char header[] = - PID XPRI NICE SIZE RES STATE WAIT TIMECPU COMMAND; + PID XPRI NICE SIZE RES STATE WAIT TIMECPU #C COMMAND; /* 0123456 -- field to fill in starts at header+6 */ #define UNAME_START 6 #define Proc_format \ - %5d %-8.8s %3d %4d %5s %5s %-9s %-7.7s %6s %5.2f%% %s + %5d %-8.8s %3d %4d %5s %5s %-9s %-7.7s %6s %5.2f%% %2d %s /* process state names for the STATE column of the display */ /* @@ -496,7 +496,7 @@ (pp-p_stat == SSLEEP pp-p_slptime maxslp) ? idle : state_abbr(pp), p_wait, format_time(cputime), 100.0 * pct, - printable(format_comm(pp))); + pp-p_cpuid, printable(format_comm(pp))); *pid = pp-p_pid; /* return the result */

Re: asynchronous I/O
Iguess the short answers is that it is not implemented and probably it won't. There are certain applications that would certainly benefit from aio. The one I can think of (it is the one I use the most) is I/O trace replay. But I am sure that there are plenty of applications that can benefit from this facility. It is true that aio can be easily implemented having an I/O handler thread. But it is always nice to have a library that do it for you ;) Thanks for your responses, Luis On Fri, Dec 4, 2009 at 5:45 PM, Ted Unangst ted.unan...@gmail.com wrote: On Fri, Dec 4, 2009 at 4:45 PM, Todd T. Fries t...@fries.net wrote: Does aio really require threading? In some sense, yes, in others, no. aio is designed so you don't need (userland) threads. Normally you'd write your server to use non-blocking io. But that doesn't work with files on disk. How can it? With network sockets, you have somebody on the other end pushing data into your pipe which the kernel buffers. But the file system isn't going to read stuff from disk until you ask for it, there's no somebody else pushing data at you. That's what aio is for. It starts up a disk request without waiting for it. Then you can come back and get the result. Think of it as preemptive polling. Instead of calling select()/poll() to find out what's _ready_ for io, you call aio and then later it tells you what's _done_ with io. A normal implementation would be purely kernel based, with a few new syscalls. But the kernel would still need to keep track of all the buffers and io requests. So at that level, there's still something resembling threading. This is all fairly easy to fake in userland. When somebody calls aio_read(), just spin up a thread that calls read() until done. The main process goes on with its work, magic happens in the background. Of course, this requires the ability for one thread to execute while another is blocked, which the uthreads implementation we have doesn't have.

Re: ASN Flow Exporter for OpenBGP device
On 2009-12-04, Eduardo Meyer dudu.me...@gmail.com wrote: I have an OpenBGP device and I need to find out which ASN demands more bandwidth to do some sort of traffic policy engineering. Therefore I need to know if there is any software that is able to export netflow data including SRC/DST AS on an OpenBGP system. take a look at pmacct, it's in ports/packages. it can collect netflow data and peer bgp (quagga-based code) to add ASN information, but as far as I know the bgp code hasn't been tested on OpenBSD yet.
SIGCHLD and libpthread.so
Hi,
I see that SIGCHLD which was sent before calling sigaction() for
SIGCHLD is delivered to the handler when program is linked to
libpthread.so. However, this behavior doesn't occur when program
isn't linked to libpthread.so.
I feel the behavior of SIGCHLD when linked to libpthread.so
is strange, but I don't know whether the behavior is correct
or not.
Can anyone tell me what happened?
Best Regards,
Jun Kawai

How can I get my driver bug fix committed?
About two weeks ago, I sent a fix for the ral(4) driver ([PATCH] Fix interrupt handling in ral(4) for RT2661 under load, http://www.mail-archive.com/t...@openbsd.org/msg01155.html). I have not gotten any response from any OpenBSD developers, and I have not seen the patch committed. I'm happy to answer any questions about the patch, revise it, or do whatever it takes to move this forward, but it is very disheartening to have my efforts to contribute a bug fix simply get ignored. What am I doing wrong? Thanks, Roland
