[PATCH 2/6][RFC] audit: add arch field to seccomp event log
The AUDIT_SECCOMP record looks something like this:
type=SECCOMP msg=audit(1373478171.953:32775): auid=4325 uid=4325 gid=4325 ses=1
subj=unconfined_u:unconfined_r:unconfined_t:s0 pid=12381 comm="test" sig=31
syscall=231 compat=0 ip=0x39ea8bca89 code=0x0
In order to determine what syscall 231 maps to, we need to have the arch= field right
before it.
To see the event, compile this test.c program:
=====
int main(void)
{
return seccomp_load(seccomp_init(SCMP_ACT_KILL));
}
=====
gcc -g test.c -o test -lseccomp
After running the program, find the record by: ausearch --start recent -m SECCOMP -i
