From 84db564aad45774ab64375ee019d5e7a42675b1f Mon Sep 17 00:00:00 2001 From: Richard Guy Briggs Date: Wed, 29 Jan 2014 16:17:58 -0500 Subject: [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 Signed-off-by: Richard Guy Briggs signed-off-by: Eric Paris --- kernel/auditsc.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/kernel/auditsc.c b/kernel/auditsc.c index dff2a2325655..9f03ac205e1f 100644 --- a/kernel/auditsc.c +++ b/kernel/auditsc.c @@ -67,6 +67,7 @@ #include #include #include +#include #include #include #include @@ -2488,11 +2489,9 @@ void __audit_seccomp(unsigned long syscall, long signr, int code) if (unlikely(!ab)) return; audit_log_task(ab); - audit_log_format(ab, " sig=%ld", signr); - audit_log_format(ab, " syscall=%ld", syscall); - audit_log_format(ab, " compat=%d", is_compat_task()); - audit_log_format(ab, " ip=0x%lx", KSTK_EIP(current)); - audit_log_format(ab, " code=0x%x", code); + audit_log_format(ab, " sig=%ld arch=%x syscall=%ld compat=%d ip=0x%lx code=0x%x", + signr, syscall_get_arch(), syscall, is_compat_task(), + KSTK_EIP(current), code); audit_log_end(ab); } -- 2.34.1
