-Subject: [PATCH 1/4] Smack: File receive for sockets
-
-The existing file receive hook checks for access on
-the file inode even for UDS. This is not right, as
-the inode is not used by Smack to make access checks
-for sockets. This change checks for an appropriate
-access relationship between the receiving (current)
-process and the socket. If the process can't write
-to the socket's send label or the socket's receive
-label can't write to the process fail.
-
-This will allow the legitimate cases, where the
-socket sender and socket receiver can freely communicate.
-Only strangly set socket labels should cause a problem.

-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.
