Re: [PATCH] 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 --- kernel/auditsc.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/kernel/auditsc.c b/kernel/auditsc.c index 6874c1f..c464d44 100644 --- a/kernel/auditsc.c +++ b/kernel/auditsc.c @@ -2412,6 +2412,7 @@ void __audit_seccomp(unsigned long syscall, long signr, int code) return; audit_log_task(ab); audit_log_format(ab, " sig=%ld", signr); + audit_log_format(ab, " arch=%x", current->audit_context->arch);
