From 1b5d783c94c328d406e801566f161adcfb018dda Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 19 Jun 2011 12:49:47 -0400 Subject: consolidate BINPRM_FLAGS_ENFORCE_NONDUMP handling new helper: would_dump(bprm, file). Checks if we are allowed to read the file and if we are not - sets ENFORCE_NODUMP. Exported, used in places that previously open-coded the same logics.
