Re: calling syscalls directly from asm
Date:Sat, 14 Jul 2007 18:48:46 +0200 To: misc@openbsd.org From:Vincent GROSS [EMAIL PROTECTED] Subject: calling syscalls directly from asm Hi folks, I would like to call write(2) without going through the libc functions. I wrote this little thing to test, it does not print anything, but friends say it works just fine with linux. I did check the addresses and operands in the resulting binary with objdump, everything has the correct values. What am I doing wrong ? Feel free to cluebat me to death if I missed some obvious point ... ... I don't know what you hope to accomplish by avoiding the use of libc. But if you really want to do that, you'll need to know that the system call interface is completely different on linux than openbsd. Here's assembly code to call write on linux: .globl write write: pushl %ebx movl8(%esp),%ebx# fd movl12(%esp),%ecx # buffer movl16(%esp),%edx # count movl$4,%eax # __NR_write int $128 popl%ebx testl %eax,%eax jl cerror_ ret cerror_: negl%eax movl%eax,errno movl$-1,%eax movl$-1,%edx ret In linux, parameters are passed in the registers, the error code is returned as a negative number. Here's assembly code to call write on openbsd: .globl write write: movl$4,%eax # SYS_write int $128 jb cerror_ ret cerror_: movl%eax,errno movl$-1,%eax movl$-1,%edx ret On OpenBSD, parameters are passed on the stack. The kernel cleverly copies stuff from the stack just where the C calling conventions left them, which is why you don't see any code here to muck with that. An error is indicated by setting the carry flag. Incidently, there are better ways to do hexadecimal conversion. That is, assuming you really don't want to use libc. For instance, consider how you might use this: *--cp = 0123456789abcdef [ n 15 ]; -Marcus Watts

OpenBGPd: RIB ok, FIB shows local-address instead of eBGP neighbor / Box freezes
Hello, in the last weeks I played around a much with OpenBGPd, ifstated, vlans, carp, pf and pfsync. I have some trouble, but could always fix the problem or find a workaround. Because I don't have many I can do without on the production site of my setup, I run my tests only with one eBGP session. Now I want to take my pair of routers in production state and went to the datacenter last night. When I took up another two eBGP-Session I can recognize two things: Via one carped vlan I can reach two eBGP Neighbors. Both sessions came up and the router is learning his fullfeed. But when I tried to reach a target via this connection it fails! bgpctl sh rib looks fine. I can see the target network, the diferent as-paths (and the choosen one) and the ip of my next-hop. But when I take a look at bgpcgl sh fib the mentioned gateway is _my_ local ip address as given in the bgpd.conf with local-address. Having a look at the kernel routing table with route get ip shows me an route with the correct interface, but without any gateway. After finishing learning the three full feeds and a couple of minutes the console of the box freezes! First I thought this is a hardware issue and switched to another box - the same. No messages on the console, nothing in the log files. Routing works fine for a some further minutes, but not long. Any ideas? I would be appreciative if you can give me a hint how to solve this two problems! Regards, Falk

As far as I remember I'm running OpenBSD 4.1 GENERIC#320 on these boxes. btw, this is not really useful information unless the machine arch is known (and then it's only useful for snapshots, from the numbering I guess you run an i386 snap, but pleases don't make people guess when it's unnecessary :-) Even with that information, it's only useful to people with a log of build dates vs. numbers. (I guess developers may have this, others usually don't). If it's a snapshot then `sysctl kern.version` is probably good enough (though `dmesg` is always better, and less to type :) if you build yourself then the checkout date and version numbers of relevant files would be helpful.

But at the moment the box is at the datacenter and is switched off because of the freeze-problem. I could have mentioned the arch, you're right with your assuming it its i386. Later this day I will drive to the datacenter again and will update the box. That's the time where I can copy all config-files and the dmesg-output.

Allocate more memory than 512 MB with squid
Hi all, I use the squid web-proxy on a OpenBSD 4.1 i386 machine with 1024 MB of RAM. Squid can only allocate 512 MB of RAM. If squid tries to allocate more than that, the process kills himself and starts automatically again with the following message in /var/log/messages. FATAL: xcalloc: Unable to allocate 4096 blocks of 1 bytes! Squid runs under the user _squid. This user is in the login class daemon in which the data size is set to infinity. I also checked the file /usr/src/sys/arch/i386/include/vmparam.h where I found the line. #define MAXDSIZ (1024*1024*1024) /* max data size */ Can anybody give me a hint where I can set the maximum RAM usage of one process?

Part of my reason for asking on OBSD is that I'm exploring the larger issue of licensing. I know that OBSD folk tend to prefer stuff with a BSD license rather than that GPL. Only because they're in the business of making and distributing free operating systems. GPL software makes it difficult to distribute compiled binaries (because you must comply with GPL constraints on source distribution), and in turn restricts people who are making and distributing products derived from OpenBSD. BSD takes a very free definition of free, which includes you are free to take this stuff and turn it into a product, sell it, and not give your customers the source code. For example, Microsoft took the Windows TCP/IP stack from BSD - they couldn't have used the Linux one. So, the BSD licence is much more generous than GPL. However, if you are an end-user, and don't intend packaging or selling your own product which includes this functionality, then using GPL'd software is fine. In some ways it's better for you, because if you got a binary distribution and the original vendor goes bust, you should still have the source and be able to maintain it yourself. I agree that the apsfilter licence(*) is extremely unclear. However, it is published on the Internet for anyone to download. Do you believe the author would take you to court for not sending a postcard? Pragmatically, if the software does want you want, I suggest you could take that (minimal) risk. Or, just send the guy a postcard. He obviously likes them. Regards, Brian.

Whether or not it is ready for your app, that you will have to decide by putting it to your own tests. File system work is scary. It requires a measure of brilliance and optimism in a rare combination. Usually when people have that much brilliance, they look at the risks and run screaming in terror. The question of why is quite valid. Most applications I can think of for multi-TB file systems could be better done with several small file systems. At work, we have an app that will create massive amounts of data over its life span, running on an OS that DOES support multi-TB partitions. With less than 300GB in use currently, people are starting to appreciate my advice to keep the partitions well under 1TB in size...and 500GB is starting to look really, really big. Nick.

There's no problem on following those instructions. I happened to find out that the problem on this case was not related to my configuration or openbsd itself, but to a modification on the mysqld_safe script made by the previous administrator of this server, i found this: -- echo Starting $MYSQLD daemon with databases from $DATADIR ulimit -a echo --- ulimit -n 2048 /dev/null 21 # FIX para open files echo --- ulimit -a -- So that was the reason i couldn't complete a full mysqlcheck on all databases, i was limited by that ulimit on mysqld_safe which wouldn't let me open more that 2048 files despite of what i configured in my.cnf.

You plugged in bigger numbers. That could very well be your problem. Also there should be some correspondence to the numbers in login.conf and my.cnf. Another thing to watch out for: the login.conf syntax is extremely unforgiving, an extra space or tab after a \ can ruin your day. -Otto And now i have this configuration: I start mysql with this script:

And the hard drive is new , but i will format it and check if it shows up some errors. I hope it is hardware related , i would get kind of scared otherwise. Do you need me to try anything else with this filesystem? If possible (if it's not too large and the drive cooperates), I would like a dd of the partition. I'm always very interested in having an image of a filesystems on which fsck_ffs chokes. -Otto I have been getting the exact same error (CANNOT READ: BLK 64) on two different servers since I updated them to 4.1. I can happily provide a dd of the partition if it would help to resolve this. yes, please. Something like dd if=/dev/rsd0a of=image bs=512 gzip the image and make it available to me. Althoiugh I will be on vacation soo, dunno if I have time to check things before that. -Otto
