1.5 and PB 1.123

[Cyrille Demaret]

Hi,

 

We're encountering some new crash problems since the new version of
punkbuster released on 08/01 (version 1.123) with a server running no mods
(no pk3 in the main folder except the originals ones). The server is
crashing randomly with a segmentation fault. I've made a strace and it seems
to happen when punkbuster  is writing the html file for a screenshot. Here's
2 strace output:

 

open("/home/cdw/.callofduty/pb/svss/pb000635.htm", O_WRONLY|O_CREAT|O_TRUNC,
0666) = 20

fstat64(20, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0

old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0x49a2f000

--- SIGSEGV (Segmentation fault) @ 0 (0) ---

+++ killed by SIGSEGV +++

 

 

And 

 

open("/home/cdw/.callofduty/pb/svss/pb000622.htm", O_WRONLY|O_CREAT|O_TRUNC,
0666) = 20

fstat64(20, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0

old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0x49a2f000

--- SIGSEGV (Segmentation fault) @ 0 (0) ---

+++ killed by SIGSEGV +++

 

 

Here's the gdb output of the first strace :

 

(gdb) bt

#0  0x401c7e53 in strlen () from /lib/libc.so.6

#1  0x40198435 in vfprintf () from /lib/libc.so.6

#9  0x080d4ad9 in strcpy ()

#10 0x40161d06 in __libc_start_main () from /lib/libc.so.6

(gdb)

 

When the server is not crashing, the old_mmap result is 0x4dff0000 and here
it's 0x49a2f000. I don't know what this function is doing and what the
result is meaning.

 

The server is making a lot of others screenshots before crashing and it's
not related to a free space problem on the disk. I have tested with an old
version of pb (1.106) and there's no such problems. I know that this problem
is not related to the linux server binary but It can help us to identify
server's problems and third party problems.

 

Does anyone else have the same problems?

 

Sincerely,

 

Cyrille
