1439823d6f dovecot: allow reading /proc/sys/fs/suid_dumpable
This is needed if a dovecot child process segfaults - in this case,
dovecot provides a helpful error message like

dovecot[6179]: auth-worker: Fatal: master: service(auth-worker): child 8103 killed with signal 11 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set /proc/sys/fs/suid_dumpable to 2)

which involves reading the current value in suid_dumpable.

c98222686a Backport lots of .gitignore additions from 2.12
The only entries that wouldn't be needed in 2.11 are

- cscope.*
- libraries/libapparmor/src/PMurHash.lo
- libraries/libapparmor/src/PMurHash.o

but they don't hurt, and keeping .gitignore in sync in all branches
makes things easier.

bcd9db816c parser: ignore feature abi rules
AppArmor 3.0 requires policy to use a feature abi rule for access to
new features. However some policy may start using abi rules even if
they don't have rules that require new features.  This is especially
true for out of tree policy being shipped in other packages.

Add enough support to older releases that the parser will ignore the
abi rule and warn that it is falling back to the apparmor 2.x
technique of using the system abi.

If the profile contains rules that the older parser does not
understand it will fail policy compilation at the unknown rule instead
of the abi rule.

[2.10] Initialize hats that don't exist in the /etc/apparmor.d profile yet

If a hat only exists in the to-be-merged profile, it needs to be
initialized in the /etc/apparmor.d/ profile. This patch does exactly
that to avoid an aa-mergeprof crash.

This bug only exists in the 2.10 branch. Newer branches already got it
"accidently fixed" during merging ask_the_questions() into aa.py and the
ProfileStorage implementation.

0efbd7a68e libapparmor: Finish removing LD_RUN_PATH from Makefile.perl
commit 94dfe15b28 attempted to remove
LD_RUN_PATH unfortunately

   But all it actually does is cause the Makefile.perl to embed the rpath
    "" instead. Which is still an rpath, only I guess an even worse one.

    --
    Eli Schwartz
    Arch Linux Bug Wrangler and Trusted User

This is because it cleared the setting of the variable LD_RUN_PATH
which was expanded in the command

$(INST_DYNAMIC) : $(OBJECT) $(MYEXTLIB) $(INST_ARCHAUTODIR)$(DFSEP).exists $(EXPORT_LIST) $(PERL_ARCHIVEDEP) $(PERL_ARCHIVE_AFTER) $(INST_DYNAMIC_DEP)
	$(RM_F) $@
	 LD_RUN_PATH="$(LD_RUN_PATH)" $(LD)  $(LDDLFLAGS) $(LDFROM) $(OTHERLDFLAGS) -o $@ $(MYEXTLIB) \
	  $(PERL_ARCHIVE) $(LDLOADLIBS) $(PERL_ARCHIVE_AFTER) $(EXPORT_LIST) \
	  $(INST_DYNAMIC_FIX)
	$(CHMOD) $(PERM_RWX) $@

resulting in LD_RUN_PATH="" being passed to the command.

Finish removing LD_RUN_PATH from Makefile.perl by removing it from
the command invocation if it is present.

Note: we use \x24 instead of $ in the regex as there seems to be a bug
and no level of escaping $ would allow it to be used.

49bd73172e Merge branch 'apparmor-2.10' into 'apparmor-2.10'
2.10: Add basic support for abi rules to the tools

Add basic "understand and keep" support for abi rules, where
"understand" means to not error out when seeing an abi rule, and "keep"
simply means to keep the original abi rule when serializing a profile.

On the long term, abi rules should be parsed (similar to include rules),
but for now, this patch is the smallest possible changeset and easy to
backport.

Note that the only added test is via cleanprof_test.* which is used by
minitools_test.py - and does not run if you do a 'make check'.
Oh, and of course the simple_tests/abi/ files also get parsed by
test-parser-simple-tests.py.

BTW: Even serialize_profile_from_old_profile() can handle abi rules ;-)

This is a backport of 072d3e04 / !202 (merged) to
2.10 (with some adjustments because that commit didn't appy cleanly)

6aba270cc8 comment out use_group to remove group restrictions
use_group is only honored if it is defined.

The "real" permission check is reading the logfile - the group check
in aa-notify is just an annoying additional check, and the default
"admin" only works on Ubuntu (other distributions typically use
"wheel").

This commit comments out use_group in the default config, which allows
everybody to use aa-notify. Permissions for reading the log file are of
course still needed.

The mount regression test passes MS_MANDLOCK to the mount(2) syscall in

CONFIG_MANDATORY_FILE_LOCKING set, attempting to mount a filesystem with
this option always fails with EPERM. To fix, convert the test program to
use the MS_NODEV option instead.

9d4cac38e2 parser: add support for conditional includes
This is a minimal patch to add conditional includes to the profile
language.

The syntax for conditional includes is similar to regular includes
except with the addition of "if exists" after "include"

  include if exists <foo/bar>
  include if exists "foo/bar"
  include if exists "/foo/bar"
  include if exists foo/bar

Note: The patch is designed to be backportable with minimum
effort. Cleanups and code refactoring are planned for follow up
patches that won't be back ported.

367710384d parser: fix parser so that cache creation failure doesn't cause load failure
This is a minimal patch so that it can be backported to 2.11 and 2.10
which reverts the abort on error failure when the cache can not be
created and write-cache is set.

This is meant as a temporary fix for
https://bugzilla.suse.com/show_bug.cgi?id=1069906
https://bugzilla.opensuse.org/show_bug.cgi?id=1074429

where the cache location is being mounted readonly and the cache
creation failure is causing policy to not be loaded. And the
thrown parser error to cause issues for openQA.

Note: A cache failure warning will be reported after the policy load.

95d2b6ed3d parser: Allow AF_UNSPEC family in network rules
https://launchpad.net/bugs/1546455

Don't filter out AF_UNSPEC from the list of valid protocol families so
that the parser will accept rules such as 'network unspec,'.

There are certain syscalls, such as socket(2), where the LSM hooks are
called before the protocol family is validated. In these cases, AppArmor
was emitting denials even though socket(2) will eventually fail. There
may be cases where AF_UNSPEC sockets are accepted and we need to make
sure that we're mediating those appropriately.

2e1d4f5b67 libapparmor: fix swig test_apparmor.py for zero length ptrace records
Merge from trunk revision 3715

The added testcase for a ptrace target with an empty string
(ptrace_garbage_lp1689667_1.in) was causing the swig python test script
to fail. The generated python swig record for libapparmor ends up
setting a number of fields to None or other values that indicate the
value is unset, and the test script was checking if the value in the
field didn't evaluate to False in a python 'if' test.

Unfortunately, python evaluates the empty string '' as False in 'if'
tests, resulting in the specific field that contained the empty string
to be dropped from the returned record. This commit fixes that by
special case checking for the empty string.

68af901615 utils: Add aa-remove-unknown utility to unload unknown profiles
https://launchpad.net/bugs/1668892

This patch creates a new utility, with the code previously used in the
init script 'restart' action, that removes unknown profiles which are
not found in /etc/apparmor.d/. The functionality was removed from the
common init script code in the fix for CVE-2017-6507.

The new utility prints a message containing the name of each unknown
profile before the profiles are removed. It also supports a dry run mode
so that an administrator can check which profiles will be removed before
unloading any unknown profiles.

If you backport this utility with the fix for CVE-2017-6507 to an
apparmor 2.10 release and your backported aa-remove-unknown utility is
sourcing the upstream rc.apparmor.functions file, you'll want to include
the following bug fix to prevent the aa-remove-unknown utility from
removing child profiles that it shouldn't remove:

9dd1cbec0a parser: Preserve unknown profiles when restarting apparmor init/job/unit
CVE-2017-6507

https://launchpad.net/bugs/1668892

The common AppArmor 'restart' code used by some init scripts, upstart
jobs, and/or systemd units contained functionality that is no longer
appropriate to retain. Any profiles not found /etc/apparmor.d/ were
assumed to be obsolete and were unloaded. That behavior became
problematic now that there's a growing number of projects that maintain
their own internal set of AppArmor profiles outside of /etc/apparmor.d/.
It resulted in the AppArmor 'restart' code leaving some important
processes running unconfined. A couple examples are profiles managed by
LXD and Docker.

d47fdc7b42 regression tests: fix environ fail case
merge from trunk commit revision 3630

In the environ regression test, when the exec() of the child process
fails, we don't report FAIL to stdout, so the regression tests consider
it an error rather than a failure and abort, short-circuiting the
test script.

This commit fixes this by emitting the FAIL message when the result
from the wait() syscall indicates the child process did not succeed.

860ccb3b13 Dovecot profile: change Px to mrPx for /usr/lib/dovecot/*
Some of the /usr/lib/dovecot/* rules already have mrPx permissions,
while others don't.

With a more recent kernel, I noticed that at least auth, config, dict,
lmtp, pop3 and ssl-params need mrPx instead of just Px (confirmed by the
audit.log and actual breakage caused by the missing mr permissions).

The mr additions for anvil, log and managesieve are just a wild guess,
but I would be very surprised if they don't need mr.

e5daa5fa39 logparser.py: improve file vs. network event recognition
Sometimes network events come with an operation keyword looking like
file_perm which makes them look like file events. Instead of ignoring
these events (which was a hotfix to avoid crashes), improve the type
detection.

In detail, this means:
- replace OPERATION_TYPES (which was basically a list of network event
  keywords) with OP_TYPE_FILE_OR_NET (which is a list of keywords for
  file and network events)
- change op_type() parameters to expect the whole event, not only the
  operation keyword, and rebuild the type detection based on the event
  details
- as a side effect, this simplifies the detection for file event
  operations in parse_event_for_tree()
- remove workaround code from parse_event_for_tree()

Also add 4 new testcases with log messages that were ignored before.

b15f758490 logparser.py parse_event(): always store family, protocol and sock_type
Storing these event details depending on the operation type only makes
things more difficult because it's hard to differenciate between file
and network events.

Note that this happens at the first log parsing stage (libapparmor log
event -> temporary python array) and therefore doesn't add a serious
memory footprint. The event tree will still only contain the elements
relevant for the actual event type.

This change means that lots of testcases now get 3 more fields (all
None) when testing parse_event(), so update all affected testcases.
(test-network doesn't need a change for probably obvious reasons.)

Also rename a misnamed test in test-change_profile.

Note: 2.10 has fewer rule classes, therefore less test-*.py files need
to be changed. Also, I had to slightly adjust the logparser.py patch
because 2.10 doesn't have support for signal events.

ae595aea03 Fix 'alias' rule description in apparmor.d manpage
The apparmor.d description about alias rules was broken in multiple
ways. The manpage
- didn't include the   alias   keyword
- listed alias rules in the "COMMA RULES" section - while that's correct
  for the comma requirement, it's also wrong because COMMA RULES is
  meant to be inside a profile
- didn't list alias rules in the PREAMBLE section

44f2c6d2bc [39/38] Ignore exec events for non-existing profiles
The switch to FileRule made some bugs visible that survived unnoticed
with hasher for years.

If aa-logprof sees an exec event for a non-existing profile _and_ a
profile file matching the expected profile filename exists in
/etc/apparmor.d/, it asks for the exec mode nevertheless (instead of
being silent). In the old code, this created a superfluous entry
somewhere in the aa hasher, and caused the existing profile to be
rewritten (without changes).

However, with FileRule it causes a crash saying

      File ".../utils/apparmor/aa.py", line 1335, in handle_children
        aa[profile][hat]['file'].add(FileRule(exec_target, file_perm, exec_mode, rule_to_name, owner=False, log_event=True))
    AttributeError: 'collections.defaultdict' object has no attribute 'add'

This patch makes sure exec events for unknown profiles get ignored.



Reproducer:

    python3 aa-logprof -f <(echo 'type=AVC msg=audit(1407865079.883:215): apparmor="ALLOWED" operation="exec" profile="/sbin/klogd" name="/does/not/exist" pid=11832 comm="foo" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0 target="/sbin/klogd//null-1"')

This causes a crash without this patch because
/etc/apparmor.d/sbin.klogd exists, but has
    profile klogd /{usr/,}sbin/klogd {

28d5c335af aa-genprof: ask about profiles in extra dir (again)
Thanks to reading the wrong directory in read_inactive_profiles()
(profile_dir instead of extra_profile_dir), aa-genprof never asked about
using a profile from the extra_profile_dir.

Sounds like an easy fix, right? ;-)

After fixing this (last chunk), several other errors popped up, one
after the other:
- get_profile() missed a required parameter in a serialize_profile() call
- when saving the profile, it was written to extra_profile_dir, not to
  profile_dir where it (as a now-active profile) should be. This is
  fixed by removing the filename from existing_profiles{} so that it can
  pick up the default name.
- CMD_FINISHED (when asking if the extra profile should be used or a new
  one) behaved exactly like CMD_CREATE_PROFILE, but this is surprising
  for the user. Remove it to avoid confusion.
- displaying the extra profile was only implemented in YaST mode
- get_pager() returned None, not an actual pager. Since we have 'less'
  hardcoded at several places, also return it in get_pager()

Finally, also remove CMD_FINISHED from the get_profile() test in
test-translations.py.


(test-translations.py is only in trunk, therefore this part of the patch
is obviously trunk-only.)

ad169656bf dbus-session-strict: allow access to the user bus socket
From: Simon McVittie <simon.mcvittie@collabora.co.uk>
Date: Wed, 4 May 2016 13:48:36 +0100
Subject: dbus-session-strict: allow access to the user bus socket

If dbus is configured with --enable-user-bus (for example in the
dbus-user-session package in Debian and its derivatives), and the user
session is started with systemd, then the "dbus-daemon --session" will be
started by "systemd --user" and listen on $XDG_RUNTIME_DIR/bus. Similarly,
on systems where dbus-daemon has been replaced with kdbus, the
bridge/proxy used to provide compatibility with the traditional D-Bus
protocol listens on that same socket.

In practice, $XDG_RUNTIME_DIR is /run/user/$uid on all systemd systems,
where $uid represents the numeric uid. I have not used /{var/,}run here,
because systemd does not support configurations where /var/run and /run
are distinct; in practice, /var/run is a symbolic link.

Based on a patch by Sjoerd Simons, which originally used the historical
path /run/user/*/dbus/user_bus_socket. That path was popularized by the
user-session-units git repository, but has never been used in a released
version of dbus and should be considered unsupported.

0f7ccc49bb syscall_sysctl test: correctly skip if CONFIG_SYSCTL_SYSCALL=n
From: Simon McVittie <simon.mcvittie@collabora.co.uk>
Date: Wed, 11 May 2016 13:52:56 +0100
Subject: syscall_sysctl test: correctly skip if CONFIG_SYSCTL_SYSCALL=n

This test attempts to auto-skip the sysctl() part if that syscall
was not compiled into the current kernel, via
CONFIG_SYSCTL_SYSCALL=n. Unfortunately, this didn't actually work,
for two reasons:

* Because "${test} ro" wasn't in "&&", "||", a pipeline or an "if",
  and it had nonzero exit status, the trap on ERR was triggered,
  causing execution of the error_handler() shell function, which
  aborts the test with a failed status. The rules for ERR are the
  same as for "set -e", so we can circumvent it in the same ways.
* Because sysctl_syscall.c prints its diagnostic message to stderr,
  but the $() operator only captures stdout, it never matched

90e5294578 load variables in ask_the_questions()
Variables can be used in several rule types (from the existing *Rule
classes: change_profile, dbus, ptrace, signal). It seems nobody uses
variables with those rules, otherwise we'd have received a bugreport ;-)

I noticed this while working on FileRule, where usage of variables is
more common. The file code in bzr (not using a *Rule class) already
loads the variables, so old versions don't need changes for file rule
handling.

However, 2.10 already has ChangeProfileRule and therefore also needs
this fix.

61ee9623c5 Prevent crash caused by serialize_profile_from_old_profile()
If a profile file contains multiple profiles and one of those profiles
contains a rule managed by a *Ruleset class,
serialize_profile_from_old_profile() crashes with an AttributeError.

This happens because profile_data / write_prof_data contain only one
profile with its hats, which explodes if a file contains multiple
profiles, as reported in lp#1528139

Fixing this would need lots of
    write_prof_data[hat] -> write_prof_data[profile][hat]
changes (and of course also a change in the calling code) or, better
option, a full rewrite of serialize_profile_from_old_profile().

Unfortunately I don't have the time to do the rewrite at the moment (I
have other things on my TODO list), and changing write_prof_data[hat] ->
write_prof_data[profile][hat] is something that might introduce more
breakage, so I'm not too keen to do that.

Therefore this patch wraps the serialize_profile_from_old_profile() call
in try/except. If it fails, the diff will include an error message and
recommend to use 'View Changes b/w (C)lean profiles' instead, which is
known to work.

Note: I know using an error message as 'newprofile' isn't an usual way
to display an error message, but I found it more intuitive than
displaying it as a warning (without $PAGER).

458f696f8e dovecot-lda profile: allow tempfiles and executing sendmail
dovecot-lda needs to read and write /tmp/dovecot.lda.*.

It also needs to be able to execute sendmail to send sieve vacation
mails.

For now, I'm using a child profile for sendmail to avoid introducing a
new profile with possible regressions. This child profile is based on
the usr.sbin.sendmail profile in extras and should cover both postfix'
and sendmail's sendmail.
I also mixed in some bits that were needed for (postfix) sendmail on my
servers, and dropped some rules that were obsolete (directory rules not
ending with a /) or covered by an abstraction.

In the future, we might want to provide a stand-alone profile for
sendmail (based on this child profile) and change the rule in the
dovecot-lda profile to Px.

Don't split namespaces from profile names using YACC grammar. Instead,

This fixes a bug that caused the profile keyword to not be used with a
label containing a namespace in the profile declaration.

Fixing this bug uncovered a bad parser test case at
simple_tests/profile/profile_ns_ok1.sd. The test case mistakenly
included two definitions of the :foo:unattached profile despite being
marked as expected to pass. I've adjusted the name of one of the

If a profile file contains multiple profiles, aa-mergeprof crashes on
saving in write_profile() because the second profile in the file is not

This patch first checks if 'changed' contains the profile before

f5df1bf45e Remove pname to bin_name mapping in autodep()
If autodep() is called with a pname starting with / (which can happen
for (N)amed exec depending on the user input), this pname is mapped to
bin_name.

This might look like a good idea, however if the given pname doesn't
exist as file on-disk, autodep() returns None instead of a (mostly
empty) profile. (Reproducer: choose (N)amed, enter "/foo/bar")

Further down the road, this results in two things:
a) the None result gets written as empty profile file (with only a "Last
   modified" line)
b) a crash if someone chooses to add an abstraction to the None, because
   None doesn't support the delete_duplicates() method for obvious
   reasons ;-)


Unfortunately this patch also introduces a regression - aa-logprof now
fails to follow the exec and doesn't ask about the log events for the
exec target anymore. However this doesn't really matter because of a) -
asking and saving to /dev/null vs. not asking isn't a real difference
;-)


Actually the patch slightly improves things - it creates a profile for
the exec target, but only with the depmod() defaults (abstractions/base)
and always in complain mode.

I'd prefer a patch that also creates a complete profile for the exec
target, but that isn't as easy as fixing the issues mentioned above and
therefore is something for a future fix. To avoid we forget it, I opened
https://bugs.launchpad.net/apparmor/+bug/1545155


Note: 2.9 "only" writes an empty file and doesn't crash - but writing
an empty profile is still an improvement.

483f11d06c Fix handling of link events in aa-logprof
handle_children() has some special code for handling link events with
denied_mask = 'l'. Unfortunately this special code depends on a regex
that matches the old, obsolete log format - in a not really parsed
format ("^from .* to .*$").

The result was that aa-logprof did not ask about events containing 'l'
in denied_mask.

Fortunately the fix is easy - delete the code with the special handling
for 'l' events, and the remaining code that handles other file
permissions will handle it :-)

- convert keys() result to a set to avoid test failures because of

218cb42fbe Adjust type(x) == str checks in the rule classes for py2
python 3 uses only the 'str' type, while python 2 also uses 'unicode'.
This patch adds a type_is_str() function to common.py - depending on the
python version, it checks for both. This helper function is used to keep
the complexity outside of the rule classes.

The rule classes get adjusted to use type_is_str() instead of checking
for type(x) == str, which means they support both python versions.

Finally, add test-common.py with some tests for type_is_str().

cfbc1a2a79 parser: Honor the --namespace-string commandline option
https://launchpad.net/bugs/1526085

Revno 2934 'Add fns to handle profile removal to the kernel interface'
introduced a regression in the parser's namespace support by causing the
--namespace-string option to be ignored. This resulted in the profile(s)
being loaded into the global namespace rather than the namespace
specified on the command line.

This patch fixes the bug by setting the Profile object's ns member, if
the --namespace-string option was specified, immediately after the
Profile object is allocated.

d5824674d1 Several fixes for variable handling
Parsing variables was broken in several ways:
- empty quotes (representing an intentionally empty value) were lost,
  causing parser failures
- items consisting of only one letter were lost due to a bug in RE_VARS
- RE_VARS didn't start with ^, which means leading garbage (= syntax
  errors) was ignored
- trailing garbage was also ignored

This patch fixes those issues in separate_vars() and changes
var_transform() to write out empty quotes (instead of nothing) for empty
values.

Also add some tests for separate_vars() with empty quotes and adjust
several tests with invalid syntax to expect an AppArmorException.

var_transform() gets some tests added.

Finally, remove 3 testcases from the "fails to raise an exception" list
in test-parser-simple-tests.py.

4c0e6334b5 Fix parsing/storing bare file rules
We replaced parse_audit_allow() with parse_modifiers() in r2833, but
overlooked that parse_modifiers() returns allow/deny as boolean. This
resulted in storing bare file rules in aa[profile][hat]['path'][False]
instead of aa[profile][hat]['path']['allow'] (or True instead of 'deny'
for 'deny file,' rules), with the user-visible result of loosing bare
file rules when saving the profile.

This patch converts the boolean value from parse_modifiers back to a
string.

Note: 2.9 is not affected because the old parse_audit_allow() returns
'allow' or 'deny' as string, not as boolean.

274a98d8aa Let 'make check' work without logprof.conf
This patch checks if the cfg object is empty (happens if logprof.conf
doesn't exist). If so, it adds some empty sections to prevent various
failures in code that expects those sections to exist.

Another source of failures was using cfg['section']['setting']. The
patch changes various places to cfg['section'].get('setting') to prevent
those failures. (Those places all have a 'or ...' fallback.)

Finally, find_first_file() in config.py crashed if file_list was Null.
This is fixed by adding an "if file_list:" check before trying to
split() it.

With all those changes applied, 'make check' will work even if
/etc/apparmor/logprof.conf doesn't exist.


The patch also fixes the default value for inactive_profiledir
(I missed aa.py when I changed it to /usr/share/apparmor/extra-profiles/)

3fa19feb43 Parse all parser simple_tests with the utils code
Add a testcase that parses all tests in the parser/tst/simple_tests/
directory with parse_profile_data() to ensure that everything with valid
syntax is accepted, and that all tests marked as FAIL raise an
exception.

This already resulted in
- several patches to fix low-hanging fruits (including some bugs in the
  parser simple_tests itsself)
- a list of tests that don't behave as expected. Those files get their
  expected result reverted to make sure we notice any change in the
  tools behaviour, especially changing to the really expected resulted.
  This method also makes sure that the testcase doesn't report any of
  the known failures.
- a 5% improvement in test coverage - mostly caused by nearly completely
  covering parse_profile_data.
- addition of some missing testcased (as noticed by missing coverage),
  for example several "rule outside of a profile" testcases.

As indicated above, the tools don't work as expected on all test
profiles - most of the failures happen on expected-to-fail tests that
pass parse_profile_data() without raising an exception. There are also
some tests failing despite valid syntax, often with rarely used syntax
like if conditions and qualifier blocks.

Most of the failing (generated) tests are caused by features not
implemented in the tools yet:
- validating dbus rules (currently we just store them without any parsing)
- checks for conflicting x permissions
- permissions before path ("r /foo,")
- 'safe' and 'unsafe' keywords for *x rules
- 'Pux' and 'Cux' permissions (which actually mean PUx and CUx, and get
  rejected by the tools - ideally the generator script should create
  PUx and CUx tests instead)

skip_startswith excludes several generated tests from being run. I know
that skip_startswith also excludes tests that would not fail, but the
generated filenames (especially generated_x/exact-*) don't have a
pattern that I could easily use to exclude less tests - and I'm not too
keen to add a list with 1000 single filenames ;-)

06885e9377 Reset aa and original_aa in read_profiles()
TL;DR: aa-genprof crashes with a wrong 'Conflicting profiles' error.

aa-genprof uses autodep() to create a basic profile, which is then
stored in aa and original_aa. After that, read_profiles() is called,
which reads all profiles (including the new one) from disk, causing a
(wrong) 'Conflicting profiles' error in attach_profile_data() because
the autodep()-generated profile is already there.

Therefore this patch resets aa and original_aa in read_profiles() to

- reading /etc/syslog-ng/conf.d/
- reading the journal
- reading /etc/machine-id (it's unclear why this is needed, therefore
  I don't want abstractions/dbus-session-strict for now)
- write access to /run/syslog-ng.ctl

ddc56bf3ac Accept more log formats in logparser.py
logparser.py does a regex check on log lines as performance improvement
so that it only hands over lines that look like AppArmor events to
LibAppArmor parsing. Those regexes were incomplete and didn't cover all
log formats LibAppArmor accepts, with the end result of "overlooking"
events.

This patch splits off common parts of the regex, adds more regexes for
several log types and finally merges everything into one regex.

test-libapparmor-test_multi.py now also checks all test_multi log lines
against the regex to ensure logparser.py doesn't silently ignore events.

test-logparser.py gets adjusted to the merged RE_LOG_ALL regex.

Finally, add a new test that was posted on IRC to the test_multi set.

9a315c9ef0 parser: make caching tests not fail w/python <= 3.2
In recent commits, Tyler fixed some problems with the caching behavior
of the parser, as well as adjusting and improving the caching test
script to verify these behaviors.

In doing so, the test script adjusts the mtime of various
files and ensures that the written files have the expected mtime
timestamp. Unfortunately, the os.utime() function used to adjust mtime
in python 3.2 (as included in Ubuntu 12.04 LTS) does not update with
nanosecond precision, even though the timestamps returned by os.stat()
do have precision to nanoseconds. This causes the tests to fail when
running under python 3.2 with errors like the following:

  ======================================================================
  FAIL: test_abstraction_newer_rewrites_cache (__main__.AAParserCachingTests)
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "/��PKGBUILDDIR��/parser/tst/testlib.py", line 50, in new_unittest_func
      return unittest_func(self)
    File "./caching.py", line 424, in test_abstraction_newer_rewrites_cache
      self._set_mtime(self.abstraction, abstraction_mtime)
    File "./caching.py", line 238, in _set_mtime
      self.assertEquals(os.stat(path).st_mtime, mtime)
  AssertionError: 1440337039.40212 != 1440337039.4021206

The following patch creates a new time stamp equality assertion
function that detects if it's running on python 3.2 or earlier, and
loosens the equality bounds when comparing the passed timestamps. On
python 3.3 and newer, where writing timestamps with nanosecond precision
is supported, the strict equality assertion is used.

(Note: I did not convert all time stamp comparisons, just ones where
the timestamp written and checked could be based on a timestamp
derived from os.stat().)

97591bb512 parser: Run caching tests even when apparmorfs is not mounted
The contents of the policy cache files varies based on kernel feature
support found in apparmorfs but the caching tests are mostly about
whether or not a cache file was generated and with the right timestamps.

This patch makes it so that the tests are not entirely skipped when
apparmorfs is not available. Instead, a flat features file will be used
in most cases and only the specific tests that require apparmorfs will
be skipped.

7c937bb370 parser: Verify cache file mtime in caching tests
This makes several improvements to the parser caching tests to verify
that the parser is properly consuming the mtime of profiles and
abstractions when dealing with the policy cache.

It introduces a simple abstraction file and tests the mtime handling by
changing the mtime on the profile, abstraction, apparmor_parser, and
cache file in various combinations to check the parser's behavior.

5c58cdd351 parser: Fix cache file mtime regression
This patch fixes a regression in setting the cache file's timestamp
handling that was introduced in r3079:

  Set cache file tstamp to the mtime of most recent policy file tstamp

The previously used utimes(2) syscall requires a two element timeval
array. The first element in the array is the atime to be used and the
second element is the mtime. The equivalent of a one element timeval
array was being passed to it, resulting in garbage being used for the
mtime value. The utimes(2) syscall either failed, due to the invalid
input, or set mtime to an unexpected value. The return code wasn't being
checked so the failure went unknown.

This patch switches to utimensat(2) for a couple reasons. The UTIME_OMIT
special value allows us to preserve the inode's atime without calling
stat(2) to fetch the atime. It also allows for nanosecond precision
which better aligns with what stat(2) returns on the input profile and
abstraction files. That means that we can have the exact same mtime on
the input profile or abstraction file and the output cache file.

842a592b0d regression tests: make sysctl(2) test a bit more resiliant
In testing against the 4.1 kernel, the syscall_sysctl testcase started
failing even in the unconfined case. What the test program does is
attempt to adjust the kernel.threads-max sysctl to be slightly larger
and see if the operation succeeds by reading the value back out. It
also attempts to save the original value and restore it. The test
was failing because (in VMs at least) the default value chosen by
the kernel for the kernel.threads-max setting was high enough that
attempts to increase it would be ignored (likely to prevent too much
use of kernel memory by threads), helpfully without any message being
report to dmesg. Thus, the initial read of the current value would
succeed, the write of that value + 1024 would appear to succeed,
but then reading the value back out and comparing it to the expected
value would fail, as it would still be the original value, not the
expected new value.

This patch attempts to address this by first attempting to raise
the value, and if that does not appear to work, to then attempt
to lower it.  It also refactors the code a bit by creating helper
functions to perform the actual sysctl(2) calls to make the code a
bit easier to read.

c9e16d874e Check for duplicate profiles
Having two profiles for the same binary is "technically allowed", but it
leads to interesting[tm] behaviour because one of them "wins" depending
on the load order. To make things even more interesting, the kernel load
order can be different from the tools load order, leading to even more
fun.

Short version: you do _not_ want that situation ;-)

This patch adds a duplicate check to attach_profile_data() so that it
errors out if it finds duplicate profiles or hats, and lists the profile
files that contain them.

426edf3233 Fix name_to_prof_filename() error behaviour
In some cases, the return value of name_to_prof_filename() is undefined.
This happens when deleting the to-be-confined binary while running
aa-genprof and leads to a not-too-helpful
    File "/usr/lib/python3/dist-packages/apparmor/aa.py", line 265, in enforce
	      prof_filename, name = name_to_prof_filename(path)
	TypeError: 'NoneType' object is not iterable

(reported by maslen on IRC)

This patch makes sure name_to_prof_filename() always returns None, None
(instead of undefined aka just None) so that at least the caller can
successfully split it into two None values.

For the exotic aa-genprof usecase given above, this at least improves
the error message to
    Can't find $binary_name
(raised by enforce() via fatal_error())


The patch also changes fatal_error() to display the traceback first, and
the human-readable message at the end, which makes it more likely that
the user actually notices the human-readable message.

986bbf90f9 Fix aa_log_end_msg() in rc.apparmor.suse
"rcapparmor kill" results in a funny error message:
    /lib/apparmor/rc.apparmor.functions: line 441: return: -v: invalid option
    return: usage: return [n]

SLE12 includes a patch that prevents this error message, but also
prevents that $? is handed over correctly to rc_status. This means that
"rcapparmor kill" will happily display "done" even with a compiled-in
apparmor module that can't be unloaded.

This patch is the improved version - it adds a small helper function to
set $? (as handed over to aa_log_end_msg()) and then calls rc_status -v.
This means that "rcapparmor kill" now shows "failed" because it's
impossible to unload something that is compiled directly into the
kernel.

=head1 NAME
aa_stack_profile, aa_stack_onexec - combine multiple profiles to confine a task
=head1 SYNOPSIS
B<#include E<lt>sys/apparmor.hE<gt>>
B<int aa_stack_profile(const char *profile);>
B<int aa_stack_onexec(const char *profile);>
Link with B<-lapparmor> when compiling.
=head1 DESCRIPTION
AppArmor supports stacking two or more profiles when confining a task. The
result is an intersection of all profiles which are stacked. Stacking profiles
together is desirable when wanting to ensure that confinement will never become
more permissive. When changing between two profiles, as performed with
aa_change_profile(2), there is always the possibility that the new profile is
more permissive than the old profile but that possibility is eliminated when
using aa_stack_profile().
To stack a profile with the current confinement context, a task can use the
aa_stack_profile() function. The I<profile> parameter is a NUL-terminated
string indicating a profile name that should be stacked with the current
confinement.
Calling aa_stack_profile("profile_a") while unconfined is equivalent to calling
aa_change_profile("profile_a") since the intersection of unconfined and
"profile_a" is "profile_a". Calling aa_stack_profile("profile_b") while
confined by "profile_a" results in the task's confinement to be the
intersection of "profile_a" and "profile_b". The resulting confinement context
will be represented as "profile_a//&profile_b" in audit log messages, the
return value of aa_getcon(2), etc.
Confined programs wanting to use aa_stack_profile() need to have rules
permitting stacking the named profile. See apparmor.d(8) for details.
Open file descriptors may not be remediated after a call to aa_stack_profile()
so the calling program must close(2) open file descriptors to ensure they
are not available after calling aa_stack_profile().
The aa_stack_onexec() function is like the aa_stack_profile() function
except it specifies that the stacking should take place on the next exec
instead of immediately. The delayed profile change takes precedence over any
exec transition rules within the confining profile. Delaying the stacking
boundary has a couple of advantages, it removes the need for stub transition
profiles and the exec boundary is a natural security layer where potentially
sensitive memory is unmapped.
=head1 RETURN VALUE
On success zero is returned. On error, -1 is returned, and
errno(3) is set appropriately.
=head1 ERRORS
=over 4
=item B<EINVAL>
AppArmor is not loaded, neither a profile nor a namespace was specified,
or the communication via the F</proc/*/attr/current> file did not conform
to protocol.
=item B<ENOMEM>
Insufficient kernel memory was available.
=item B<ENOENT>
The specified profile does not exist, or is not visible from the current
namespace.
=back
=head1 NOTES
Using aa_stack_profile() and related libapparmor functions are the only way to
ensure compatibility between varying kernel versions. However, there may be
some situations where libapparmor is not available and directly interacting
with the AppArmor filesystem is required to stack a profile.
To immediately stack a profile named "profile_a", as performed with
aa_stack_profile("profile_a"), the equivalent of this shell command can be
used:
$ echo -n "stackprofile profile_a" > /proc/self/attr/current
To stack a profile named "profile_a" at the next exec, as performed with
aa_stack_onexec("profile_a"), the equivalent of this shell command can be used:
$ echo -n "stackexec profile_a" > /proc/self/attr/exec
These raw AppArmor filesystem operations must only be used when using
libapparmor is not a viable option.
=head1 EXAMPLE
The following example shows a simple, if contrived, use of
aa_stack_profile().
#include <stdlib.h>
#include <string.h>
#include <sys/apparmor.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
static void read_passwd()
{
int fd;
char buf[10];
if ((fd=open("/etc/passwd", O_RDONLY)) < 0) {
perror("Failure opening /etc/passwd");
_exit(1);
}
/* Verify that we can read /etc/passwd */
memset(&buf, 0, 10);
if (read(fd, &buf, 10) == -1) {
perror("Failure reading /etc/passwd");
_exit(1);
}
buf[9] = '\0';
printf("/etc/passwd: %s\n", buf);
close(fd);
}
int main(int argc, char * argv[])
{
printf("Before aa_stack_profile():\n");
read_passwd();
/* stack the "i_cant_be_trusted_anymore" profile, which
* should not have read access to /etc/passwd. */
if (aa_stack_profile("i_cant_be_trusted_anymore") < 0) {
perror("Failure changing profile -- aborting");
_exit(1);
}
printf("After aa_stack_profile():\n");
read_passwd();
_exit(0);
}
This code example requires a profile similar to the following to be loaded

=head1 BUGS
None known. If you find any, please report them at
L<https://bugs.launchpad.net/apparmor/+filebug>. Note that using
aa_stack_profile(2) without execve(2) provides no memory barriers between
different areas of a program; if address space separation is required, then
separate processes should be used.

AppArmor provides an easy abstraction mechanism to group common
access requirements; this abstraction is an extremely flexible way to
grant site-specific rights and makes writing new AppArmor profiles very
simple by assembling the needed building blocks for any given program.
The use of '#include' is modelled directly after cpp(1); its use will
replace the '#include' statement with the specified file's contents.
The leading '#' is optional, and the '#include' keyword can be followed
by an option conditional 'if exists' that specifies profile compilation
should continue if the specified file or directory is not found.
