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 Signed-off-by: Richard Guy Briggs <rgb@redhat.com> signed-off-by: Eric Paris <eparis@redhat.com>
