Subject: apparmor-utils: Fix handling of files in /
References: bnc#397883
The separate handling of files and directories with realpath is broken.
For files e.g. /foo, $dir ends up being empty since the / is eaten by
the regex. realpath resolves an empty argument as the current directory,
resulting in an incorrect path.
There's no explanation of why the separate handling was used in the
first place.

Subject: apparmor-utils: setprofileflags() drops leading whitespace
References: bnc#480795
setprofileflags() drops leading whitespace for subprofiles. writeheader()
properly indents subprofiles 2 spaces per nesting level but when
genprof sets the profile to enforce mode at completion, the whitespace
is removed.
This patch adds the whitespace globbing to the regexp and uses it to
prefix the sub-profile with the correct spacing.

Subject: apparmor-utils: Inherit flags in sub-profiles when generating profiles
References: bnc#496204
When creating profiles with cx subprofiles, genprof will set the
sub-profile in enforce mode. When genprof cycles multiple times, it
prohibits the sub-profile from working correctly.
e.g.
# Last Modified: Mon Jan 24 13:52:26 2011
#include <tunables/global>
/home/jeffm/mycat flags=(complain) {
#include <abstractions/base>
#include <abstractions/bash>
#include <abstractions/consoles>
/bin/bash ix,
/bin/cat cx,
/home/jeffm/mycat r,
profile /bin/cat {
#include <abstractions/base>
/bin/cat r,
/home/jeffm/mycat r,
}
}
This patch allows sub-profiles to inherit the flags from the parent
profile, which allows it to be created in complain mode (if appropriate).
The temporary complain flags are cleaned up at genprof completion as
expected.

Subject: Subdomain.pm: Fix for null path
References: bnc#407959
When handling the following log entry, logprof will spew perl errors and
ultimately generate an invalid config: "r,"
Since there is nothing to do with a null path, just skip to the next entry.
type=APPARMOR_DENIED msg=audit(1214497030.421:39): operation="inode_permission" info="Failed name resolution - object not a valid entry" requested_mask="r" denied_mask="r" pid=31367 profile="/usr/sbin/httpd2-worker

Subject: apparmor: Subdomain.pm: Fix handling of audits of unconfined processes
The version of AppArmor that was accepted into the mainline kernel
issues audit events for things like change_hat while unconfined.
Previous versions just returned -EPERM without the audit.
This results in logprof and friends spewing uninitialized value errors
when it hits events like:
type=AVC msg=audit(1291742101.899:220): apparmor="DENIED" operation="change_hat" info="unconfined" error=-1 pid=28005 comm="cron
... which happen any time an unconfined process does something with pam
when pam_apparmor is installed.
This patch skips those events.
[Note that the second half of the OpenSUSE patch had already been applied.]

Subject: [PATCH] apparmor-utils: cleanup after abort in genprof
References: bnc#307067
The initial generation of the base profile is required to be written out
to put the process in complain mode for observation. If the user
decides to abort the profiling session, that base profile is left
behind.
This patch removes all profiles created during the run up to an abort.
Signed-off-by: Jeff Mahoney <jeffm@suse.com>
This patch fixes a logprof bug where when profiles with variable
declarations at the top level (not hidden in an include) were written
back to a file, a trailing comma was being added to the declaration
statement, which is invalid apparmor policy syntax. This patch corrects
this and no longer adds the trailing comma.
Subject: apparmor: Fix network event parsing
References: bnc#665483
The upstream version of AppArmor had network mediation but it was
removed. There's a compability patch floating around that both openSUSE
and Ubuntu have applied to their kernels. Unfortunately, one part was
overlooked. The socket operation event names where changed from the
socket_ prefixed names they had when AppArmor was out-of-tree and
utils/SubDomain.pm was never updated to understand them.
This patch adds an operation-type table so that the code can just
do a optype($operation) call to discover what type of operation a
particular name refers to. It then uses this in place of the socket_
checks to decide whether an event is a network operation.
This allows genprof and logprof to work with networking rules again.

"SubDomain" in some way. This leaves only "subdomain.conf" and the
function names internally.
Additionally, I added a "make check" rule to the utils/Makefile to do a
simple "perl -c" sanity check just for good measure.
