[PATCH 1/1] IMA: open new file for read

From: Mimi Zohar
Date: Wed Sep 02 2009 - 11:40:54 EST


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.
