Subject: KEYS: Fix keyring ref leak in join_session_keyring()
|
||||
|
||||
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.
