From 5e7575c6690a2871a1db5d5fe86c8fe8aef00cd8 Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Fri, 20 Apr 2018 14:55:59 -0700 Subject: [PATCH] autofs: mount point create should honour passed in mode commit 1e6306652ba18723015d1b4967fe9de55f042499 upstream. The autofs file system mkdir inode operation blindly sets the created directory mode to S_IFDIR | 0555, ingoring the passed in mode, which can cause selinux dac_override denials. But the function also checks if the caller is the daemon (as no-one else should be able to do anything here) so there's no point in not honouring the passed in mode, allowing the daemon to set appropriate mode when required.
