FYI: SIGTRAP after execve is generated by kernel here:
include/linux/tracehook.h
static inline void tracehook_report_exec(struct linux_binfmt *fmt,
struct linux_binprm *bprm,
struct pt_regs *regs)
{
if (!ptrace_event(PT_TRACE_EXEC, PTRACE_EVENT_EXEC, 0) &&
unlikely(task_ptrace(current) & PT_PTRACED))
send_sig(SIGTRAP, current, 0);
}
