Eric Biggers 4bcf6f827a fscrypt: check for NULL keyring in fscrypt_put_master_key_activeref() ... It is a bug for fscrypt_put_master_key_activeref() to see a NULL keyring. But it used to be possible due to the bug, now fixed, where fscrypt_destroy_keyring() was called before security_sb_delete(). To be consistent with how fscrypt_destroy_keyring() uses WARN_ON for the same issue, WARN and leak the fscrypt_master_key if the keyring is NULL instead of dereferencing the NULL pointer. This is a robustness improvement, not a fix. Link: https://lore.kernel.org/r/20230313221231.272498-4-ebiggers@kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com>		2023-03-18 21:08:03 -07:00
