From 1924fe5874a85f2b25ebb38089e11a6a637e8441 Mon Sep 17 00:00:00 2001 From: Tyler Hicks Date: Tue, 24 Jan 2012 10:02:22 -0600 Subject: [PATCH] eCryptfs: Fix oops when printing debug info in extent crypto functions commit 58ded24f0fcb85bddb665baba75892f6ad0f4b8a upstream. If pages passed to the eCryptfs extent-based crypto functions are not mapped and the module parameter ecryptfs_verbosity=1 was specified at loading time, a NULL pointer dereference will occur. Note that this wouldn't happen on a production system, as you wouldn't pass ecryptfs_verbosity=1 on a production system. It leaks private information to the system logs and is for debugging only. The debugging info printed in these messages is no longer very useful and rather than doing a kmap() in these debugging paths, it will be better to simply remove the debugging paths completely. https://launchpad.net/bugs/913651 Signed-off-by: Tyler Hicks Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
