41091fd411 parser: call filter slashes for the dbus path conditional
Similar to unix addr rules, the dbus path conditional is more a path
than a profile name and should get its slashes filtered after variable

b5ffee530b parser: enable variable expansion for mount type= and options=
Currently mount options type= and options= do not expand variables
but they should. Fix it.

Note: this does not treat either as paths because their use is
too device dependent for it to be safe to filter slashes.

ab49c3dbb0 libapparmor: add missing include for socklen_t
While `include/sys/apparmor.h` makes use of `socklen_t`, it doesn't
include the `<sys/socket.h>` header to make its declaration available.
While this works on systems using glibc via transitive includes, it
breaks compilation on musl libc.

Fix the issue by including the header.

92a6360570 libapparmor: add _aa_asprintf to private symbols
While `_aa_asprintf` is supposed to be of private visibility, it's used
by apparmor_parser and thus required to be visible when linking. This
commit thus adds it to the list of private symbols to make it available
for linking in apparmor_parser.

f4346f63f6 parser: Fix expansion of variables in unix rules addr= conditional
The parser is not treating unix addr as a path and filtering slashes
after variable expansion. This can lead to errors where

@{foo}=/a/
unix bind addr=@{foo}/bar,

will always fail because addr is being matched as /a//bar instead of
/a/bar.

6eef48828c regression tests: Don't build syscall_sysctl if missing kernel headers
sys/sysctl.h is not guaranteed to exist anymore since
https://sourceware.org/pipermail/glibc-cvs/2020q2/069366.html

which is a follow on to the kernel commit
61a47c1ad3a4 sysctl: Remove the sysctl system call

While the syscall_sysctl currently checks if the kernel supports
sysctrs before running the tests. The tests can't even build if the
kernel headers don't have the sysctl defines.

The only entries that wouldn't be needed in 2.11 are

- libraries/libapparmor/src/PMurHash.o

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

that to avoid an aa-mergeprof crash.

This bug only exists in the 2.10 branch. Newer branches already got it

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
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.

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.

Some of the /usr/lib/dovecot/* rules already have mrPx permissions,

With a more recent kernel, I noticed that at least auth, config, dict,

audit.log and actual breakage caused by the missing mr permissions).

The mr additions for anvil, log and managesieve are just a wild guess,

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.

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

This patch fixes this.

It also moves the definition of VARIABLE, VARIABLE ASSIGNMENT (both
unchanged) and ALIAS RULE next to PREAMBLE.

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
  in the string comparison. This is easily solved by redirecting
  its stderr to stdout.

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.

bdb18c5ccf Update abstractions/ssl_* for acmetool-generated certificates
acmetool is an alternative client for Let's Encrypt.
(https://github.com/hlandau/acme/)

It stores the certificates etc. in the following directory layout:

    /var/lib/acme/live/<domain> -> ../certs/<hash>
    /var/lib/acme/certs/<hash>/cert
    /var/lib/acme/certs/<hash>/chain
    /var/lib/acme/certs/<hash>/privkey -> ../../keys/<hash>/privkey
    /var/lib/acme/certs/<hash>/url
    /var/lib/acme/certs/<hash>/fullchain
    /var/lib/acme/keys/<hash>/privkey

This patch adds the needed permissions to the ssl_certs and ssl_keys
abstractions so that the certificates can be used.

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 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

da0daadf40 parser: Allow the profile keyword to be used with namespaces
https://launchpad.net/bugs/1544387

Don't split namespaces from profile names using YACC grammar. Instead,
treat the entire string as a label in the grammer. The label can then be
split into a namespace and a profile name using the new parse_label()
function.

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
profiles to :foo:unattached2.

6d05fa4a6e 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.

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.

ec9292bd5e utils: handle versioned ruby interpreters
Merge from trunk revision 3353

On Debian and Ubuntu it's possible to have multiple ruby interpreters
installed, and the default to use is handled by the ruby-defaults
package, which includes a symlink from /usr/bin/ruby to the versioned
ruby interpreter.

This patch makes aa.py:get_interpreter_and_abstraction() take that into
account by using a regex to match possible versions of ruby. Testcases
are included. (I noticed this lack of support because on Ubuntu the
ruby test was failing because get_interpreter_and_abstraction()
would get the complete path, which on my 16.04 laptop would get
/usr/bin/ruby2.2.)

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 :-)

b54d1f2049 Write unix rules when saving a profile
r2637 added support for parsing unix rules, but forgot to add write
support. The result was that a profile lost its unix rules when it was

This patch adds the write_unix_rules() and write_unix() functions (based
on the write_pivot_root() and write_pivot_root_rules() functions) and
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.)

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

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().

3ab596ed83 Fix logparser.py crash on change_hat events
'change_hat' events have the target profile in 'name2', not in 'name'
(which is None and therefore causes a crash when checking if it contains
'//')

Also add the log event causing this crash to the libapparmor testsuite.

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.

(which also implies 2.10)


Note: 2.9 doesn't have test-parser-simple-tests.py, therefore it won't
get that part of the patch.

f6dcade84f Change abstract methods in BaseRule to use NotImplementedError
As Kshitij mentioned, abstract methods should use NotImplementedError
instead of AppArmorBug.

While changing this, I noticed that __repr__() needs to be robust against
NotImplementedError because get_raw() is not available in BaseRule.
Therefore the patch changes __repr__() to catch NotImplementedError.

Of course the change to NotImplementedError also needs several
adjustments in the tests.

0f4310d301 Map c (create) log events to w instead of a
Creating a file is in theory covered by the 'a' permission, however
discussion on IRC brought up that depending on the open flags it might
not be enough (real-world example: creating the apache pid file).

Therefore change the mapping to 'w' permissions. That might allow more
than needed in some cases, but makes sure the profile always works.

68041e0d2e Add debug info to profile_storage()
For debugging, it's helpful to know which part of the code initialized a
profile_storage and for which profile and hat this was done.

This patch adds an 'info' array with that information, adds the
corresponding parameters to profile_storage() and changes the callers to
deliver some useful content.

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.

dfe58983bb utils/test/Makefile: add libapparmor to PYTHONPATH
The last utils/test/Makefile change switched to using the in-tree
libapparmor by default (unless USE_SYSTEM=1 is given). However, I missed
to add the swig/python parts of libapparmor to PYTHONPATH, so the
system-wide LibAppArmor/__init__.py was always used.

This patch adds the in-tree libapparmor python module to PYTHONPATH.

I'm sorry for the interesting[tm] way to find out that path, but
a) I don't know a better / less ugly way and
b) a similar monster already works in libapparmor/swig/python/test/ ;-)

=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
with apparmor_parser(8):
# Confine stack_p to be able to read /etc/passwd and aa_stack_profile()
# to the 'i_cant_be_trusted_anymore' profile.
/tmp/stack_p {
/etc/ld.so.cache mr,
/lib/ld-*.so* mrix,
/lib/libc*.so* mr,
/etc/passwd r,
# Needed for aa_stack_profile()
/usr/lib/libapparmor*.so* mr,
/proc/[0-9]*/attr/current w,
}
As well as the profile to stack:
profile i_cant_be_trusted_anymore {
/etc/ld.so.cache mr,
/lib/ld-*.so* mrix,
/lib/libc*.so* mr,
}
The output when run:
$ /tmp/stack_p
Before aa_stack_profile():
/etc/passwd: root:x:0:
After aa_stack_profile():
Failure opening /etc/passwd: Permission denied
$
=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.
