commit: 1821df040ac3cd6a57518739f345da6d50ea9d3f From: Roberto Sassu <[email protected]> Date: Thu, 17 Mar 2011 12:48:50 +0100 Subject: [PATCH] eCryptfs: ecryptfs_keyring_auth_tok_for_sig() bug fix
The pointer '(*auth_tok_key)' is set to NULL in case request_key() fails, in order to prevent its use by functions calling ecryptfs_keyring_auth_tok_for_sig().
