-Subject: [PATCH 3/4] Smack: ignore null signal in smack_task_kill
-
-Kill with signal number 0 is commonly used for checking PID existence.
-Smack treated such cases like any other kills, although no signal is
-actually delivered when sig == 0.
-
-Checking permissions when sig == 0 didn't prevent an unprivileged caller
-from learning whether PID exists or not. When it existed, kernel returned
-EPERM, when it didn't - ESRCH. The only effect of policy check in such
-case is noise in audit logs.
-
-This change lets Smack silently ignore kill() invocations with sig == 0.
