-Subject: apparmor: Fix quieting of audit messages for network mediation
-
-If a profile specified a quieting of network denials for a given rule by
-either the quiet or deny rule qualifiers, the resultant quiet mask for
-denied requests was applied incorrectly, resulting in two potential bugs.
-1. The misapplied quiet mask would prevent denials from being correctly
- tested against the kill mask/mode. Thus network access requests that
- should have resulted in the application being killed did not.
-2. The actual quieting of the denied network request was not being applied.
- This would result in network rejections always being logged even when
- they had been specifically marked as quieted.

-Subject: UBUNTU: SAUCE: apparmor: Add the ability to mediate mount
-
-Add the ability for apparmor to do mediation of mount operations. Mount
-rules require an updated apparmor_parser (2.8 series) for policy compilation.
-
-The basic form of the rules are.
-
- [audit] [deny] mount [conds]* [device] [ -> [conds] path],
- [audit] [deny] remount [conds]* [path],
- [audit] [deny] umount [conds]* [path],
- [audit] [deny] pivotroot [oldroot=<value>] <path>
-
- remount is just a short cut for mount options=remount
-
- where [conds] can be
- fstype=<expr>
- options=<expr>
-Example mount commands
- mount, # allow all mounts, but not umount or pivotroot
