From 7762e230fd31fcc1abc03ba32ee957fadc8eafb4 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Mon, 21 Mar 2011 16:00:52 +0100 Subject: [PATCH] eCryptfs: modified size of keysig in the ecryptfs_key_sig structure The size of the 'keysig' array is incremented of one byte in order to make room for the NULL character. The 'keysig' variable is used, in the function ecryptfs_generate_key_packet_set(), to find an authentication token with the given signature and is printed a debug message if it cannot be retrieved.
