-Subject: [PATCH] KEYS: Fix keyring ref leak in join_session_keyring()
-
-This fixes CVE-2016-0728.
-
-If a thread is asked to join as a session keyring the keyring that's already
-set as its session, we leak a keyring reference.
-
-This can be tested with the following program:
-
-	#include <stddef.h>
-	#include <stdio.h>
-	#include <sys/types.h>
-	#include <keyutils.h>
-
-	int main(int argc, const char *argv[])
-	{
-		int i = 0;
-		key_serial_t serial;
-
-		serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
-				"leaked-keyring");
-		if (serial < 0) {
-			perror("keyctl");
-			return -1;
-		}
-
-		if (keyctl(KEYCTL_SETPERM, serial,
-			   KEY_POS_ALL | KEY_USR_ALL) < 0) {
-			perror("keyctl");
-			return -1;
-		}
-
-		for (i = 0; i < 100; i++) {
-			serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
-					"leaked-keyring");
-			if (serial < 0) {
-				perror("keyctl");
-				return -1;
-			}
-		}
-
-		return 0;
-	}
-
-If, after the program has run, there something like the following line in
-/proc/keys:
-
-3f3d898f I--Q---   100 perm 3f3f0000     0     0 keyring   leaked-keyring: empty
-
-with a usage count of 100 * the number of times the program has been run,
-then the kernel is malfunctioning.  If leaked-keyring has zero usages or
-has been garbage collected, then the problem is fixed.
