-Subject: 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.
