From a82a276bdb44a3b48e8f2b8dce457073c5f63123 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Thu, 17 Mar 2011 12:48:50 +0100 Subject: [PATCH] eCryptfs: ecryptfs_keyring_auth_tok_for_sig() bug fix commit 1821df040ac3cd6a57518739f345da6d50ea9d3f upstream. 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().
