Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

(Update: Today, tar works without segfault without known changes on the system. The "rm" command is now segfaulting though. Argh! Maybe this is being caused by ESXi? Or, maybe the hardware.)

I have a Centos 5.3 system running on VMWare ESXi. It's been running for quite a while without much problem. Recently, however, I noticed that the tar command and the rpm command gives me a segmentation fault when I run them.

So, I tried using strace (found someone suggested this online) and below is what I get when using strace. I'd like to know how to repair my system and how I can prevent this from happening in the future.

Thanks all in advance!

The output:

strace is not a suitable tool for determining the cause of a segfault. Install the debugging symbols for the binary and all dependent libraries, run it under gdb, and when it segfaults run 'bt' to get a backtrace, and try asking about that. –  womble Jul 11 '09 at 9:22

Even without much investigation, from your description that a few programs started to segfault, then they began to work correctly while others started failing, you have either bad memory modules, or a broken prelink.

First, stop all your virtual machines, reboot the host and run a memory test. You have to do this from outside ESXi. If you find any memory defects, that is your problem. Replace the hardware.

If no memory defects were found, check that you are running the latest available kernel from CentOS for your architecture.

Boot the host and the server again, the server in single-user mode (pass "single" to grub kernel parameters) and run:

prelink -avf

When prelink finishes, you should reboot the server. You could also do telinit u && init 3 to resume booting, but it is better to reboot in order to assure that all binaries will be reloaded with their new memory mappings.

This is a guess, but, try turning off se-linix and see if it works.

It shouldn't segfault, but, there may be a file that can't be opened because of se-linux that tar never thought would happen.

Else you'll have to install the source rpm for tar, and, build it with debugging, and then run it in the debugger to see why.

se linux is disabled. Its a production environment. tar and rpm worked fine at some point but now they fail. I suspect an update is the culprit so I was hoping someone had seen this before and knew the answer. Rebuilding tar from source (and dependencies) with debug symbols is not something I'd do. If it came to that, I would reinstall but that wouldn't tell me why this happened to begin with. –  JR Lawhorne Jul 11 '09 at 19:33

Ok, so not as complex as I thought. The server was compromised and the genius hacker screwed up the root kit install. So, the affect was binaries segfaulting. Another affect was unexpected network traffic from the server. Thanks all who responded!

Alright, sounds like great fun.

First, do you have two identically up-to-date boxes (one of which is not segfaulting)?

If so, check the md5sum on the binaries that are segfaulting, make sure they're the same.

Next, run ldd on the binaries that are failing, then run md5sum on the libraries to see if they're different.

Now, assuming the libraries are the same, something else is wrong, probably machine environment or configuration, but lets see if the strace sheds any light.

To quote your strace, near the end, you have:

 open("/proc/mounts", O_RDONLY|O_LARGEFILE) = 3
 fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f85000
 read(3, "rootfs / rootfs rw 0 0\n/dev/root"..., 4096) = 587
 read(3, "", 4096)                       = 0
 close(3)                                = 0
 munmap(0xb7f85000, 4096)                = 0

The next line is the segfault message.

On my CentOS 5.3 machine (rpm version 4.4.2.3), my rpm immediately does this:

open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=56458752, ...}) = 0
mmap(NULL, 56458752, PROT_READ, MAP_PRIVATE, 3, 0) = 0x2b36f9d01000
close(3)                                = 0

I would thus venture that the problem is either closing the memory out after reading /proc/mounts or in opening /usr/lib/locale/locale-archive. Since munmap() returned 0, I'd bark up the locale tree.

Incidentally, if your configuration excludes the locale, the next block mine executes is:

 open("/usr/lib/rpm/rpmpopt-4.4.2.3", O_RDONLY) = 3
 lseek(3, 0, SEEK_END)                   = 23100
 lseek(3, 0, SEEK_SET)                   = 0
 read(3, "#/*! \\page config_rpmpopt Defaul"..., 23100) = 23100
 close(3)

Good luck and let us know what you find.
