8c2371a7cd utils: fix writing alias rules
write_pair() ignored the 'tail' parameter, which resulted in writing
invalid alias rules (without the trailing comma).

Also add an alias to test/cleanprof.* to ensure it doesn't break again.

e3e01943d4 mount regression test: convert mount test to use MS_NODEV
The mount regression test passes MS_MANDLOCK to the mount(2) syscall in
the test program. When the kernel is configured without
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.

85881a877e Samba profile updates for ActiveDirectory / Kerberos
The Samba package used by the INVIS server (based on openSUSE) needs
some additional Samba permissions for the added ActiveDirectory /
Kerberos support.

As discussed with Seth, add /var/lib/sss/mc/initgroups read permissions
to abstractions/nameservice instead of only to the smbd profile because
it's probably needed by more than just Samba if someone uses sss.

e1415d35db 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.

bb6818a8c1 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.

0bcdaa45c0 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.

959d062f14 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.

Add several permissions to the dovecot profiles that are needed on ubuntu

As discussed some weeks ago, the added permissions use only /run/
instead of /{var/,}run/ (which is hopefully superfluous nowadays).

b0df52a7e5 utils/aa-unconfined: fix netstat invocation regression
Merge from 2.10 branch commit rev 3380

It was reported that converting the netstat command to examine
processes bound to ipv6 addresses broke on OpenSUSE due to the version
of nettools not supporting the short -4 -6 arguments.

This patch fixes the invocation of netstat to use the "--protocol
inet,inet6" arguments instead, which should return the same results
as the short options.

66280702af Handle ldd $? == 1 in get_reqs()
ldd exits with $? == 1 if a file is 'not a dynamic executable'.
This is correct behaviour of ldd, so we should handle it instead of
raising an exception ;-)

[not in 2.9 and 2.10] Also extend fake_ldd and add a test to test-aa.py to cover this.


Note that 2.10 and 2.9 don't have tests for get_reqs() nor fake_ldd,
so those branches will only get the aa.py changes.

28b8be7bcb [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 {

95aefde14c 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.)

1e0014b4a9 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.

24aa2fcd11 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

84b045b89f 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.

ae9d172f7e 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.

580d49cbf0 Fix aa-mergeprof crash with files containing multiple profiles
If a profile file contains multiple profiles, aa-mergeprof crashes on
saving in write_profile() because the second profile in the file is not
listed in 'changed'. (This happens only if the second profile didn't
change.)

This patch first checks if 'changed' contains the profile before
pop()ing it.

Reproducer: copy utils/test/cleanprof_test.in to your profile directory
and run   aa-mergeprof utils/test/cleanprof_test.out. Then just press
's' to save the profile.

7397ca0148 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.

a404f32349 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 :-)

40e24e9b29 Write unix rules when saving a profile
r2637 added support for parsing unix rules, but forgot to add write

This patch adds the write_unix_rules() and write_unix() functions (based

makes sure they get called at the right place.

The cleanprof testcase gets an unix rule added to ensure it's not
deleted when writing the profile. (Note that minitools_test.py is not
part of the default "make check", however I always run it.)

f6d84c7af5 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.

The old behaviour was a mix of both - it always used the in-tree python

For obvious reasons, you'll need to build libapparmor before running the

223322ef47 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-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.

49e82df101 regression tests: make sysctl(2) test a bit more resiliant
Merge from trunk commit rev 3219

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.

480c83343b 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.

"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.

dccd5a18cb regression tests: more ptrace adjustments for arm64 upstream changes
Merge from trunk commit 3201

In the commit "Rev 3169: regression tests: have
ptrace use PTRACE_GETREGSET by default", I created
some ifdef magic to use the per arch general purpose
register data structures for various architectures,
including arm64.  Unfortunately, in the upstream glibc commit
7d05a8168b
<bits/ptrace.h> is no longer included in the arm64 specific user.h,
which defined the structure as 'struct user_pt_regs'; instead user.h
was converted to define 'struct user_regs_struct'. Because of this,
the ptrace test fails to compile on arm64 when glibc is 2.20 or newer.

This patch adjusts the ptrace test to use the newer structure on arm64
if it's detected that a newer glibc is detected and reverts to using
the older one for older glibcs. It also adds an error when compiling
on architectures that haven't been incorporated yet.

39ebf164de Avoid raising an exception for hats in includes in aa-logprof
aa-logprof raises an exception if

- that file is included in a profile and

7a82798f6b regression tests: have ptrace use PTRACE_GETREGSET by default
Merge from trunk revision 3169

Bug: https://bugs.launchpad.net/apparmor/+bug/1470985

The ptrace regression test fails to compile on the arm64 platform,
because it uses PTRACE_GETREGS and not the newer PTRACE_GETREGSET
interface for getting access to arch-specific register information[0].
However, fixing it is complicated by the fact that the struct name
for for the general purpose registers is not named consistently
across architectures. This patch attempts to address those issues,
and compiles at least on i386, amd64, arm64, arm (armhf), ppc64,
and ppc64el. The test is verified to continue to function correctly
on i386 and amd64.

e3e77409a3 Ignore change hat declarations when parsing a profile
Hat declarations ("^hat,") were added in 2.3 for declaring external
hats, but in the meantime aren't supported by the parser anymore (tested
with 2.9.2 parser).

Additionally, if a profile contains both a hat declaration and the hat
("^hat { ...}"), the hat declaration can overwrite the content of the
hat on a "last one wins" base.

This is caused by setting 'declared' to True, which means write_piece()
will only write the "^hat," line, but not the "^hat { ... }" block.

Therefore no longer set 'declared' to True, print a warning that hat
declarations are no longer supported, and ignore the rule. This also
means that running aa-cleanprof can make the profile valid again :-)

Also no longer change 'hat' when hitting a profile declaration, which
also looks wrong.


Note: This change removes the only usage of 'declared'. A follow-up
patch (trunk only) will completely remove the 'declared' handling.


Reproducer profile (run aa-cleanprof on it):
(will crash in remove_duplicate_rules() 80% of the time - if so, try
multiple times. One of the next patches will fix that. Or just try 2.9,
which doesn't have the crash in remove_duplicate_rules().)

/usr/bin/true {

  ^FOO {
    capability setgid,
  }

  # deletes the content of ^FOO when saving the profile! (last one wins)
  # additionally, the parser says this is invalid syntax
  ^FOO,

}

can lead to cache issues when a policy file is updated separately from
the cache. This makes it possible for an update to ship a policy file
that is newer than the what the cache file was generated from, but
result in a cache hit because the cache file was local compiled after
the policy file was package into an update (this requires the update
to set the mtime of the file when locally installed to the mtime of
the file in its update archive but this is commonly done, especially
in image based updates).

6ae047d0c1 Let set_profile_flags() change the flags for all hats
It did this in the old 2.8 code, but didn't in 2.9.x (first there was a
broken hat regex, then I commented out the hat handling to avoid
breakage caused by the broken regex).

This patch makes sure the hat flags get set when setting the flags for
the main profile.

Also change RE_PROFILE_HAT_DEF to use more named matches
(leadingwhitespace and hat_keyword). Luckily all code that uses the
regex uses named matches already, which means adding another (...) pair
doesn't hurt.

Finally adjust the tests:
- change _test_set_flags to accept another optional parameter
  expected_more_rules (used to specify the expected hat definition)
- add tests for hats (with '^foobar' and 'hat foobar' syntax)
- add tests for child profiles, one of them commented out (see below)


Remaining known issues (also added as TODO notes):

- The hat and child profile flags are *overwritten* with the flags used
  for the main profile. (That's well-known behaviour from 2.8 :-/ but we
  have more flags now, which makes this more annoying.)
  The correct behaviour would be to add or remove the specified flag,
  while keeping other flags unchanged.

- Child profiles are not handled/changed if you specify the 'program'
  parameter. This means:
  - 'aa-complain smbldap-useradd' or 'aa-complain /usr/sbin/smbldap-useradd'
    _will not_ change the flags for the nscd child profile
  - 'aa-complain /etc/apparmor.d/usr.sbin.smbldap-useradd' _will_ change
    the flags for the nscd child profile (and any other profile and
    child profile in that file)


Even with those remaining issues (which need bigger changes in
set_profile_flags() and maybe also in the whole flags handling), the
patch improves things and fixes the regression from the 2.8 code.

Samba 4.2 needs some more permissions for nmbd and winbindd.

To avoid overcomplicated profiles, change abstractions/samba to allow

ead71a306a Enable testloops for nosetests
Ensure nosetests sees all tests in the tests[] tuples. This requires
some name changes because nosetests thinks all function names containing
"test" are tests. (A "not a test" docorator would be an alternative, but
that would require some try/except magic to avoid a dependency on nose.)

To avoid nosetests thinks the functions are a test,
- rename setup_all_tests() to setup_all_loops()
- rename regex_test() to _regex_test() (in test-regex_matches.py)

Also add the module_name as parameter to setup_all_loops and always run
it (not only if __name__ == '__main__').

Known issue: nosetests errors out with
    ValueError: no such test method in <class ...>: stub_test
when trying to run a single test generated out of tests[].
(debugging hint: stub_test is the name used in setup_test_loop().)

aa45be1c10 Fix crash in serialize_profile_from_old_profiles()
Assume you have a profile like

    /bin/foo {
      /etc/ r,
      network,
      /usr/ r,
    }

(important: there must be be a non-path rule between the two path blocks)

Then run aa-logprof and add another path event. When choosing (V)iew changes,
it will crash with a misleading

  File ".../utils/apparmor/aamode.py", line 205, in split_mode
      other = mode - user
      TypeError: unsupported operand type(s) for -: 'collections.defaultdict' and 'set'

The reason for this is our beloved hasher, which is playing funny games
another time.

The patch wraps the hasher usage with a check for the parent element to
avoid auto-creation of empty childs, which then lead to the above crash.


BTW: This is another issue uncovered by the LibreOffice profile ;-)

2b9260f27a Fix serialize_profile_from_old_profiles() to not crash on "@{var} +="
serialize_profile_from_old_profiles() calls store_list_var() with an
empty hasher. This fails for "+=" because in this case store_list_var()
expects a non-empty hasher with the variable already defined, and raises
an exception because of the empty hasher.

This patch sets "correct = False" if a "+=" operation appears, which
means the variable will be written in "clean" mode instead.

Adding proper support for "add to variable" needs big changes (like
storing a variable's "history" - where it was initially defined and what
got added where).

b4048cf3de logparser.py: change mask only for path events
Move the code that does the c -> a and d -> w replacement in denied_mask
and requested_mask so that it only runs for path and exec events, but not
for other events (like dbus and ptrace). The validate_log_mode() and
log_str_to_mode() calls are also moved.

Technically, this means moving code from parse_event() to the path
and exec sections in add_event_to_tree().

This also means aa-logprof no longer crashes if it hits a ptrace or
dbus event in the log.

The "if dmask:" and "if rmask:" checks are removed - if a path event
doesn't have these two, it is totally broken and worth a aa-logprof
crash ;-)

Also adjust the parse_event() tests to expect the "raw" mask instead of
a set.

Note: the 2.9 branch doesn't contain test-capability.py, therefore I
skipped this part of the patch for obvious reasons ;-)

This patch fixes
https://bugs.launchpad.net/apparmor/+bug/1426651 and
https://bugs.launchpad.net/apparmor/+bug/1243932


I manually tested that
- c and d log events are still converted to a and w
- aa-logprof handles exec events correctly
- ptrace events no longer crash aa-logprof

8a475341e8 utils: simplify serialize_parse_profile_start()
Merge from trunk revision 3001

Change serialize_parse_profile_start() to use parse_profile_start()
instead of using duplicated code.

The behaviour is mostly kept, with the exception that the function is
more strict now and raises exceptions instead of ignoring errors.

In practise, this won't change anything because the profiles are parsed
with parse_profile() (which calls parse_profile_start()) - and that
already errors out.

The tests are updated to match the more strict behaviour.

The next step would be to drop serialize_parse_profile_start()
completely, but this isn't urgent and can/should be done when we have
test coverage for serialize_profile_from_old_profile() one day ;-)

a373b4ee93 utils: implement attachment handling after rewriting set_profile_flags()
to use write_header(), and making set_profile_flags
more strict.

Merge from trunk revisions 2996, 2997, and 2998.

Changes in set_profile_flags():
- rewrite set_profile_flags to use parse_profile_start_line() and
  write_header().
- replace the silent failure for non-existing files with a proper
  exception (using lazy programming - the check is done by removing the
  "if os.path.isfile()" check, open_file_read then raises the
  exception ;-)
- comment out regex_hat_flag and the code that was supposed to handle
  hat flags, which were totally broken. We'll need another patch to fix
  it, and we also need to decide if we want to do that because it
  introduces a behaviour change (currently, aa-complain etc. don't
  change hat flags).

The tests for set_profile_flags() are also updated:
- prepend a space to comments because write_header always adds a space
  between '{' and the comment
- remove a test with superfluous quotes that are no longer kept
  (that's
  just a profile cleanup, so dropping that test is the easiest way)
- update test_set_flags_10 and test_set_flags_12 to use the correct
  profile name
- enable the tests for invalid (empty) flags
- update the test for a non-existing file

this patch makes set_profile_flags more strict:
- raise AppArmorBug if newflags contains only whitespace
- raise AppArmorBug if the file doesn't contain the specified profile or
  no profile at all

The tests are adjusted to expect AppArmorBug instead of a silent
failure. Also, some tests are added for profile=None, which means to
change the flags for all profiles in a file.
- test_set_flags_08 is now test_set_flags_invalid_04
- test_set_flags_invalid_03 is changed to only contain one reason for
  a failure, not two ;-)

Finally implement attachment handling

This patch implements attachment handling - aa-logprof now works with
profiles that have an attachment defined, instead of ignoring audit.log
entries for those profiles.

Changes:
- parse_profile_start_line(): remove workaround that merged the
  attachment into the profile name
- parse_profile_data(): store attachment when parsing a profile
- update test_parse_profile_start_03,
  test_serialize_parse_profile_start_03,
  test_set_flags_nochange_09 and some parse_profile_start_line() tests -
  they now expect correct attachment handling

  would cause a crash.
  Also add a test for 1.5 and 1.3 spaces.

- rewrite the handling of flags to avoid we have to maintain two

serialize_parse_profile_start() to use parse_profile_start_line();
update test-aa.py to match parse_profile_start() and
get_profile_flags() changes

Merge from trunk commits 2978, 2979, and 2982

Add the parse_profile_start_line() function to regex.py, which is
a wrapper for RE_PROFILE_START_2 and returns an array with named matches.

Also change some places in aa.py from using RE_PROFILE_START to
the parse_profile_start_line() function.

Notes: - until everything is migrated to the new function, I'll
keep the old
  RE_PROFILE_START unchanged - that's the reason to add the new
  regex as RE_PROFILE_START_2
- the patch changes only aa.py sections that are covered by tests
  already (which means some users of RE_PROFILE_START are remaining)
- parse_profile_start_line() merges 'profile' and 'attachment' into
  'profile' (aka the old, broken behaviour) until aa.py can handle
  the attachment properly. The alternative would be to ignore
'attachment', which would be worse.

Convert serialize_parse_profile_start() to use
parse_profile_start_line(), and adjust a test to expect an AppArmorBug
instead of an AttributeError exception.

Also add two tests (they succeed with the old and the new code).
Note that these tests document interesting[tm] behaviour - I tend to
think that those cases should raise an exception, but I'm not sure about
this because serialize_profile_from_old_profile() is a good example for
interesting[tm] code :-/

I couldn't come up with a real-world test profile that would hit those
cases without erroring out aa-logprof earlier - maybe the (more
sane-looking) parse_profiles() / serialize_parse_profile_start()
protects us from hitting this interesting[tm] behaviour.

The previous patch slightly changed the behaviour of parse_profile_start()
and get_profile_flags() - they raise AppArmorBug instead of
AppArmorException when specifying a line that is not the start of a
profile and therefore doesn't match RE_PROFILE_START_2.

This patch updates test-aa.py to expect the correct exceptions, and adds
another test with quoted profile name to ensure that stripping the
quotes works as expected.

Add better support for looping over a tests[] array to common_test.py:
- class AATest - a base class we can use for all tests, and that will
  probably get more features in the future (for example tempdir
  handling)
- setup_all_tests() - a function that iterates over all classes in the
  given file and calls setup_test_loops() for each of them
- setup_tests_loop() - a function that creates tests based on tests[]
  in the given class. Those tests call the class' _run_test() method for
  each test specified in tests[]  (inspired by setup_regex_tests() ;-)

This means we can get rid of the manually maintained tests list in
test-regex_matches.py and just need to call setup_all_tests() once in
each file.

- a demo of the code added to common_test.py

Also reset 'audit' to avoid all (remaining) rules get the audit flag
after writing an audit network rule.

Note: The first section of the function (that claims to be responsible
for bare 'network,' rules) is probably never hit - but I'm not too keen
to remove it and try it out ;-)

387de4458f Fix doubled arrow in exec rules
When parsing a profile with named exec rules, the exec target included
the arrow. This resulted in two arrows when writing the profile (and one
more each time the profile was updated).

Fix this by using the match group that only contains the exec target
without the arrow in parse_profile_data() and
serialize_profile_from_old_profile().

097eb4258f fix two issues for older linux releases
Merge from trunk revision 2975

The following patch addresses two issues on older releases:

1) In trunk commit 2911, the line 'undefine VERBOSE' was added to
   parser/tst/Makefile so that the equality tests would not generate
   verbose output when $VERBOSE != 1. Unfortunately, the 'undefine'
   keyword was not introduced in GNU Make until version 3.82. On
   distro releases like Ubuntu 12.04 LTS that include versions of Make
   older than that, make check and make clean abort when VERBOSE is
   not set to 1. The patch fixes that by setting VERBOSE to a zero
   length string if does not already equal 1.

2) In trunk commit 2923, a workaround for systemd as init was added
   to the pivot_root regression test. The workaround included a
   call to ps(1) to determine if systemd is pid 1. Unfortunately,
   in older versions of the procps package (such as the version in
   Ubuntu 12.04 LTS), 'ps -hp1' emits the warning

     Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html

   The patch below converts the ps call to 'ps hp1' which does not
   generate the warning.

0ec6ce96d2 parser: fix compilation failure of deny link rules, expand equality tests
Merge from trunk commits 2909, 2910, 2911, and 2912

BugLink: http://bugs.launchpad.net/bugs/1433829

The apparmor_parser fails to compile deny rules with only link
permissions.

  Eg.
       deny /f l,
       deny l /f,
       deny link /f -> /d,

Will all fail to compile with the following assert

  apparmor_parser: aare_rules.cc:99: Node* convert_file_perms(int, uint32_t, uint32_t, bool): Assertion `perms != 0' failed.

NOTE: this is a minimal patch a bigger patch that cleans-up and separates
      and reorganizes file, link, exec, and change_profile rules is needed

parser: Expand Equality tests

This adds several new equality tests and turned up a couple of more
bugs
https://launchpad.net/bugs/1433829
https://launchpad.net/bugs/1434018

- add link/link subset tests
- add pix, Pix, cix, Cix, pux, Pux, cux, Cux and specified profile
  transitions (/f px -> b ...)
- test equality of leading and trailing permission file rules
  ie.   /foo rw, == rw /foo,
- test that specific x match overrides generic x rule. ie.
  /** ix, /foo px, is different than /** ix, /foo ix,
- test that deny removes permission
  /f[abc] r, deny /fb r,  is differnt than /f[abc] r,

In addition to adding the new tests, it changes the output of the
equality tests, so that if the $verbose variable is not set successful
tests only output a period, with failed tests outputing the full
info.  If verbose is set the full test info is output as before.

It also does:

- make the verbose output of equality.sh honor whether or not
  the environment variable VERBOSE is set
- thereby making the output verbose when 'make check V=1' or 'make
  check VERBOSE=1' is given from within the parser/ directory. This
  will make distribution packagers happy when diagnosing build
  failures caused by test failures.
- if verbose output is not emitted and the tests were successful, emit
  a newline before printing PASS.
- verify audit and audit allow is equal
- verify audit differs from deny and audit deny
- verify deny differs from audit deny
- make the verbose text a little more useful for some cases
- correct overlap exec tests to substitute in looped perms

The fix to prevent the compiler from SEGV'ing when dumping network

https://launchpad.net/bugs/1432045

The permission accumulation routine on the backend was incorrectly setting
the audit mask based off of the exec type bits (info about the exec) and
not the actual exec permission.

This bug could have also caused permissions issues around overlapping exec
generic and exact match exec rules, except the encoding of EXEC_MODIFIERS
ensured that the
  exact_match_allow & AA_USER/OTHER_EXEC_TYPE
  test would never fail for a permission accumulation with the exec permission

to avoid that I have to pass around the full write_prof_data.

Note: The "lineno" parameter is technically superfluous - I kept it to

29b0634f34 parser: net_find_af_name: do not assume that address families are consecutive,
remove unused net_find_af_val function, and network_families array
Merge from trunk commit 2888.

net_find_af_name: do not assume that address families are consecutive

The network_families array is automatically built from AF_NAMES, which is
extracted from the defines in <bits/socket.h>. The code assumes that
network_families is indexed by the AF defines. However, since the
defines are sparse, and the gaps in the array are not packed with
zeroes, the array is shorter than expected, and the indexing is wrong.

When this function was written, the network families that were
covered might well have been consecutive, but this is no longer true:
there's a gap between AF_LLC (26) and AF_CAN (29).

This assumption caused a crash in our testing while parsing the rule
"network raw".

Remove unused net_find_af_val function, and network_families array

Like net_find_af_name, this assumed that AF_* values were consecutive.

Move the code for parsing the profile start ("/foo {") from aa.py
parse_profile_data() to a separate function parse_profile_start().

Most of the changes are just moving around code, with some small
exceptions:
- instead of handing over profile_data to parse_profile_start() to
  modify it, it sets two variables (pps_set_profile and
  pps_set_hat_external) as part of its return value, which are then
  used in parse_profile_data() to set the flags in profile_data.
- existing_profiles[profile] = file   is executed later, which means
  it used the strip_quotes() version of profile now
- whitespace / tab level changes

For example:
/usr/share/aspell/iso-8859-1.cmap
/usr/share/aspell/iso-8859-1.cset

The abstraction should allow read access to these files.

34f2c1c6ea cleanup aa-disable handling in tools.py
Remove the check if the disable directory exists. If it's really
missing, it will be auto-created by create_symlink(), so we
automagically fix things instead of annoying the user with an
error message ;-)

602decfbfc Update is_skippable_file() to match all extensions that are listed in
libapparmor _aa_is_blacklisted() - some extensions were missing in the
python code.

Also make the code more readable and add some testcases.

Notes:
- the original code additionally ignored *.swp. I didn't include that -
  *.swp looks like vim swap files which are also dot files
- the python code ignores README files, but the C code doesn't
  (do we need to add README in the C code?)

c51a68eaaf Description: Allow writes to /{,var}/run/systemd/journal/dev-log, the systemd
journal socket. On Debian and Ubuntu systems, /dev/log is a symlink to
 /run/systemd/journal/dev-log, so this access is now required in the base
 abstraction to maintain current behavior.

Coverity Support
----------------
Coverity scans are available to AppArmor developers at
https://scan.coverity.com/projects/apparmor.
In order to submit a Coverity build for analysis, the cov-build binary
must be discoverable from your PATH. See the "To Setup" section of
https://scan.coverity.com/download?tab=cxx to obtain a pre-built copy of
cov-build.
To generate a compressed tarball of an intermediate Coverity directory:
$ make coverity
The compressed tarball is written to
apparmor-<SNAPSHOT_VERSION>-cov-int.tar.gz, where <SNAPSHOT_VERSION>
is something like 2.10.90~3328, and must be uploaded to
https://scan.coverity.com/projects/apparmor/builds/new for analysis. You must
include the snapshot version in Coverity's project build submission form, in
the "Project Version" field, so that it is quickly obvious to all AppArmor
developers what snapshot of the AppArmor repository was used for the analysis.

Subject: [PATCH 01/27] apparmor: fix oops, validate buffer size in
apparmor_setprocattr()
When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.
The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.
SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.
Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
modified for the case that apparmor provides null termination.

old parent
When set atomic replacement is used and the parent is updated before the
child, and the child did not exist in the old parent so there is no
direct replacement then the new child is incorrectly added to the old
parent. This results in the new parent not having the child(ren) that
it should and the old parent when being destroyed asserting the
following error.

Subject: [PATCH 05/27] apparmor: exec should not be returning ENOENT when it
denies
The current behavior is confusing as it causes exec failures to report
the executable is missing instead of identifying that apparmor
caused the failure.

Currently logging of a successful profile load only logs the basename

the same name as the another profile in the set. Logging the hname
will ensure there is no confusion.

The target profile name was not being correctly audited in a few

passed the code to set it at apply:
Since it is always based on new_profile just drop the target var
and conditionally report based on new_profile.

When finding a child profile via an rcu critical section, the profile

before its refcount is incremented.
Protect against this by repeating the lookup if the profiles refcount
is 0 and is one its way to deletion.

Subject: [PATCH 17/27] apparmor: allow SYS_CAP_RESOURCE to be sufficient to
prlimit another task
While using AppArmor, SYS_CAP_RESOURCE is insufficient to call prlimit
on another task. The only other example of a AppArmor mediating access to
another, already running, task (ignoring fork+exec) is ptrace.
The AppArmor model for ptrace is that one of the following must be true:
1) The tracer is unconfined
2) The tracer is in complain mode
3) The tracer and tracee are confined by the same profile
4) The tracer is confined but has SYS_CAP_PTRACE
1), 2, and 3) are already true for setrlimit.
We can match the ptrace model just by allowing CAP_SYS_RESOURCE.
We still test the values of the rlimit since it can always be overridden
using a value that means unlimited for a particular resource.

Subject: [PATCH 21/27] apparmor: fix module parameters can be changed after
policy is locked
the policy_lock parameter is a one way switch that prevents policy
from being further modified. Unfortunately some of the module parameters
can effectively modify policy by turning off enforcement.
split policy_admin_capable into a view check and a full admin check,
and update the admin check to test the policy_lock parameter.

Subject: [PATCH 25/27] 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: [PATCH 01/27] apparmor: fix oops, validate buffer size in
apparmor_setprocattr()
When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.
The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.
SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.
Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
modified for the case that apparmor provides null termination.

Subject: [PATCH 03/27] apparmor: fix replacement bug that adds new child to
old parent
When set atomic replacement is used and the parent is updated before the
child, and the child did not exist in the old parent so there is no
direct replacement then the new child is incorrectly added to the old
parent. This results in the new parent not having the child(ren) that
it should and the old parent when being destroyed asserting the
following error.

Subject: [PATCH 10/27] apparmor: fix log failures for all profiles in a set
currently only the profile that is causing the failure is logged. This
makes it more confusing than necessary about which profiles loaded
and which didn't. So make sure to log success and failure messages for
all profiles in the set being loaded.

Subject: [PATCH 11/27] apparmor: fix audit full profile hname on successful
load
Currently logging of a successful profile load only logs the basename
of the profile. This can result in confusion when a child profile has
the same name as the another profile in the set. Logging the hname
will ensure there is no confusion.

Subject: [PATCH 12/27] apparmor: ensure the target profile name is always
audited
The target profile name was not being correctly audited in a few
cases because the target variable was not being set and gotos
passed the code to set it at apply:
Since it is always based on new_profile just drop the target var
and conditionally report based on new_profile.

When finding a child profile via an rcu critical section, the profile

before its refcount is incremented.
Protect against this by repeating the lookup if the profiles refcount

Subject: [PATCH 17/27] apparmor: allow SYS_CAP_RESOURCE to be sufficient to
prlimit another task
While using AppArmor, SYS_CAP_RESOURCE is insufficient to call prlimit
on another task. The only other example of a AppArmor mediating access to
another, already running, task (ignoring fork+exec) is ptrace.
The AppArmor model for ptrace is that one of the following must be true:
1) The tracer is unconfined
2) The tracer is in complain mode
3) The tracer and tracee are confined by the same profile
4) The tracer is confined but has SYS_CAP_PTRACE
1), 2, and 3) are already true for setrlimit.
We can match the ptrace model just by allowing CAP_SYS_RESOURCE.
We still test the values of the rlimit since it can always be overridden
using a value that means unlimited for a particular resource.

the policy_lock parameter is a one way switch that prevents policy

can effectively modify policy by turning off enforcement.
split policy_admin_capable into a view check and a full admin check,
and update the admin check to test the policy_lock parameter.

Subject: [PATCH 25/27] 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: [PATCH 01/27] apparmor: fix oops, validate buffer size in
apparmor_setprocattr()
When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.
The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.
SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.
Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
modified for the case that apparmor provides null termination.

Subject: [PATCH 05/27] apparmor: exec should not be returning ENOENT when it
denies
The current behavior is confusing as it causes exec failures to report
the executable is missing instead of identifying that apparmor
caused the failure.

load
Currently logging of a successful profile load only logs the basename
of the profile. This can result in confusion when a child profile has
the same name as the another profile in the set. Logging the hname
will ensure there is no confusion.

audited
The target profile name was not being correctly audited in a few
cases because the target variable was not being set and gotos
passed the code to set it at apply:
Since it is always based on new_profile just drop the target var
and conditionally report based on new_profile.
