[Systrace] Segfault

[Stefan Pinkert]

Hi,

i'm new to systrace. I've found it by reading the article "Enges Korsett" in 
the german journal "Linux Magazin". Unfortunately i've some problems with it. 
Here's my system configuration:

OS: SuSE9.0
Kernel: 2.4.24 patched with systrace
usr-systrace: usr-systrace-2004-01-09
The machine is used as a server so there's no XFree86 installed.

First of all is there anywhere a short description of the command line options 
of systrace? 

Patching and compiling the kernel wasn't a problem and until now it runs 
without any problems. The user-space tool was causing some problems but 
finally i was able to get it compiled. The first run (systrace -A /bin/ls) 
was successfull, but the second(systrace -f .systrace/bin_ls /bin/ls) died 
with a segfault. From what i can see from the strace log it seem to have 
problems with reading the policy file. Here are the corresponding lines from 
strace: 

open(".systrace/bin_ls", O_RDONLY)      = 3
fstat64(3, {st_mode=S_IFREG|0600, st_size=1206, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0x4001a000
read(3, "Policy: /bin/ls, Emulation: linu"..., 4096) = 1206
gettimeofday({1073871300, 815142}, NULL) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

The second problem i found is that i was not able to let pass any options to 
ls (systrace -A /bin/ls -l). Systrace just killed the command.

regards Stefan
