From 39fac853a758306285404368fbe392408057b136 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Wed, 6 Oct 2010 18:31:15 +0200 Subject: ecryptfs: checking return code of ecryptfs_find_auth_tok_for_sig() This patch replaces the check of the 'matching_auth_tok' pointer with the exit status of ecryptfs_find_auth_tok_for_sig(). This avoids to use authentication tokens obtained through the function ecryptfs_keyring_auth_tok_for_sig which are not valid.
