Subject: [PATCH 1/1] IMA: open new file for read
Date: Wed,  2 Sep 2009 11:40:32 -0400	[thread overview]
Message-ID: <66fbda5f63fbb20bfccf6fd3f8006718f7994ec6.1251901838.git.zohar@linux.vnet.ibm.com> (raw)

When creating a new file, ima_path_check() assumed the new file
was being opened for write. Call ima_path_check() with the
appropriate acc_mode so that the read/write counters are
incremented correctly.
