-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.
