The parser currently skips the cache if optimizations are specified
because it can not determine if the cached policy was compiled
with the specified optimization. However this causes cache misses
even if policy is cached with those options, and distros are setting
some optimizations by default.
Instead of skipping reading the cache if optimizations are set, users
can force overwriting the cache if needed, until the parser can
store aditional meta info in the cache.

The calling function and the merge() macro both make use of a variable

test script experiences "bad file descriptor" failures due to the merged

Fix this by renaming merge()'s index variables from i and j to y and z
to hopefully prevent future overlap. The better fix here would be to
convert merge() to a function but that's a more intrusive change and I
don't have an easy way to test the overlay feature.

The length of a xmatch is used to prioritize multiple profiles that
match the same path, with the intent that the more specific match wins.
Currently, the length of a xmatch is computed by the position of the
first regex character.
While trying to work around issues with no_new_privs by combining
profiles, we noticed that the xmatch length computation doesn't work as
expected for multiple regexs. Consider the following two profiles:
profile all /** { }
profile bins /{,usr/,usr/local/}bin/** { }
xmatch_len is currently computed as "1" for both profiles, even though
"bins" is clearly more specific.
When determining the length of a regex, compute the smallest possible
match and use that for xmatch priority instead of the position of the
first regex character.

Using /usr/{bin,sbin}/dbsmasq as both the profile name and attachment break compatibility with the peer=/usr/sbin/dnsmasq rule, in the libvirtd profile.
Instead specify the profile has the old name of /usr/sbin/dnsmasq and specify the attachment separately. This looks funny but it avoids breaking libvirtd and still provides the broader attachment need by distros that have merged sbin into bin.

Debian and Ubuntu have releases coming out with usr-merge in place. For
these systems, /bin and /sbin are symlinks to their respective /usr
directories. This breaks a few tests in the python utils and in the
regression tests. This patch series fixes them, mostly by performing
realpath() calls when necessary. For the ptrace regression test,
it copies the called /bin/true binary into the created temporary
directory and executes it from there. (Good for other reasons, too.)

aa-logprof errors out if it hits a log event for a non-existing profile
while a profile file with the default filename for that non-existing
profile exists. This can for example happen after adding a profile name
to a profile if audit.log still contains events for the attachment-based
profile name.
Since we ignore log events for non-existing profiles in general, drop
the code for the special case "but a file matching the default filename
for that non-existing profile exists" and also silently ignore events
for this very special non-existing profile.

(This is the 2.13 version of !249 (merged) which had a few merge conflicts in the 2.13 branch, and needs a little change (last commit) on top)

* aa-complain etc. never found profiles that have a profile name (the attachment wasn't checked)
* even if the profile name was given as parameter to aa-complain, it first did "which $parameter" so it never matched on named profiles
* profile names with alternations (without attachment specification) also never matched because the old code didn't use AARE.

aa-genprof checks if one of the profiles in the extra profile dir
matches the binary, and proposes to use that profile as a starting
point.
Since 4d722f1839 the "(V)iew profile"
option to display the proposed profile was broken.
The easiest fix is to remember the filename in the extras directory, and
display the file from there.
Sidenote: when choosing to use the extra profile, it gets written to
disk without any problems, so this bug really only affected "(V)iew
profile" to preview the proposed extra profile.

'lastline' gets merged into 'line' (and reset to None) when reading the

this means there's something unparseable at the end of the profile,

Also remove some simple_tests testcases from the 'exception_not_raised'
list - they only didn't raise the exception because the invalid rule was
the last line in the affected profile.

In the 2.13 branch (and older), 'options' is not always a dict, but can
also be None or an empty string.
Adjust the if condition in serialize_profile() so that "View changes
between clean profiles" doesn't error out.
Technical stuff first:
Replace existing_profiles (a dict with the filenames for both active and
inactive profiles) with active_profiles and extra_profiles which are
ProfileList()s and store the active profiles and those in the extra
directory separately. Thanks to ProfileList, now also the relation
between attachments and filenames is easily available.
Also replace all usage of existing_profiles with active_profiles and
extra_profiles, and adjust it to the ProfileList syntax everywhere.
With this change, several bugs in aa-complain and the other minitools
get fixed:
- aa-complain etc. never found profiles that have a profile name
(the attachment wasn't checked)
- even if the profile name was given as parameter to aa-complain, it
first did "which $parameter" so it never matched on named profiles
- profile names with alternations (without attachment specification)
also never matched because the old code didn't use AARE.

parse_profile_data() returns the parsed profiles, but writes to
existing_profiles directly.
read_profiles() calls parse_profile_data() and already handles adding
the parsed profiles to aa, original_aa or extras, which means updating
existing_profiles there is a much better place.
This commit also includes a hidden change: Previously, when parsing
include files, they were also added to existing_profiles. This is
superfluous, only real profiles need to be stored there.

Split get_profile_filename() into
- get_profile_filename_from_profile_name() (parameter: a profile name)
- get_profile_filename_from_attachment() (parameter: an attachment)
Currently both functions call get_profile_filename_orig() (formerly
get_profile_filename()) so the behaviour doesn't change yet.
The most important part of this commit is changing all
get_profile_filename() calls to use one of the new functions to make
clear if they specify a profile or an attachment/executable as
parameter.
As promised, the is_attachment parameter starts to get used in this
patch ;-)
Note: The get_new parameter (which I'll explain in the patch actually
using it) is set to True in all calls to the new functions.
The long term plan is to get rid of it in most cases (hence defaulting
to False), but that will need more testing.
(cherry picked from commit ec741424f8)
The minitools call write_profile(), write_profile_feedback_ui() and
serialize_profile() with the _attachment_ as parameter.
However, aa-logprof etc. call them with the _profile name_ as parameter.
This patch adds an is_attachment parameter to write_profile() and
write_profile_feedback_ui(). It also passes it through to
serialize_profile() via the options parameter.
If is_attachment is True, the parameter will be handled as attachment,
otherwise it is expected to be a profile name.
tools.py gets changed to set is_attachment to True when calling the
functions listed above to make clear that the parameter is an attachment.
Note: This patch only adds the is_attachment parameter/option, but
doesn't change any behaviour. That will happen in the next patch.

dc7ae28d profiles/Makefile: test abstractions against apparmor_parser
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.

resulting in LD_RUN_PATH="" being passed to the command.
Finish removing LD_RUN_PATH from Makefile.perl by removing it from

2.13: 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 :-)

The `scandirat` function is a nonstandard GNU extension, which opens a
directory relative to a file descriptor. musl libc does not implement
that function and thus cannot be used to compile libapparmor.
All our uses of `scandirat` directly scan the directory the file
descriptor is referring to, not any directory beneath the FD. Implement
a function `readdirfd()`, which gets as arguments the directory FD, the
location where to put the list of directory entries as well as a
function pointer to a comparing function. `readdirfd` will then scan all
directory entries except "." and ".." and return them via an allocated
array. The array is sorted in case the comparing function is set.

"Anything in /var/lib/flatpak/exports/share or
~/.local/share/flatpak/exports/share is essentially equivalent to
the corresponding path in /usr/{local/,}share, and is something
that has deliberately been "exported" to the rest of the system by a
Flatpak-confined app.
The only reason to prevent reading those directories would be if you do
not want the AppArmor-confined app to be able to enumerate the other
software you have installed on your system, as an anti-fingerprinting
mechanism.".

parse_profile_start(): Error out on nested child profiles

8462c39b parse_profile_start(): Error out on nested child profiles
The `secure_getenv` function is a non-POSIX compliant extension of
glibc. In contrast to the POSIX `getenv`, `secure_getenv` will return
`NULL` for all environment variables when the program is run with
escalated privileges due to an SUID or SGID bit. Some strictly
POSIX-compliant libc libraries, most notably musl libc, do not have this
function and do not wish to implement it. Thus, AppArmor cannot be
compiled on such systems.
In libapparmor, `secure_getenv` is only used to determine whether the
environment variable DEBUG_ENV_VAR has been set to enable debugging. In
case an unprivileged user runs a SUID/SGID executable linked against
libapparmor, we do not want that user to be able to get additional
information via debug output.
The fix here is to produce an error only in case where debug output is
enabled by defining ENABLE_DEBUG_OUTPUT. Otherwise, we simply define
`secure_getenv` to `NULL` to completely disable the debug output.

Getting and Setting profile represented by a glob does not work correctly

Also, add a warning stating that the profile being set represents multiple programs.

Also add a new 'install-systemd' target to the Makefile to install these
systemd-related files on (open)SUSE by default. Other distributions can
follow by adding a dependency on 'install-systemd' on their
'install-$DISTRO' target.
Note that apparmor.service has ExecStop=/bin/true to avoid that running
processes get unconfined if someone accidently types
systemctl restart apparmor (instead of using "reload")
Use aa-teardown if you really want to unload all profiles.
The files in this commit are used in openSUSE since a while, and also in
Arch Linux.
BTW: The condition on var-lib.mount is because openSUSE uses
/var/lib/apparmor/cache/ - but with the changed btrfs layout on
openSUSE, maybe I'll change that to /var/cache/apparmor/ which is
a) used by Debian and b) more sane
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.

apparmor: fix regression in network mediation when using feature pinning
When the 4.14-rc6 and earlier kernels are used with an upstream 4.13
or earlier pinned feature set, there is a regression in network
mediation where policy is not being correctly enforced, because the
compilation is completely dropping the af mediation table as expected
by pre 4.14 kernels but the 4.14 kernel is not accounting for this.

write_include() was the only user of write_single(), and write_single()
had some include-specific code. This patch gets rid of write_single().
write_include() gets a simplified version of the code instead of calling
write_single().
The tools don't support having multiple rules in one line (they expect
\n after each rule), therefore mark some of the bare_include_tests as
known failures.
console_select_and_upload_profiles() and set_profiles_local_only() both
use a local variable named 'profs'. Rename it to 'profiles'.
This is the first baby step for rewriting how aa.py stores the profiles
internally. I plan to use 'profs' as variable name instead of 'aa', and
this commit gets the result for "grep -r profs" down to 0.
Some of the regression tests are missing conditionals or have the
wrong conditionals so that they fail on current upstream kernels.
Fix this by adding and changing conditionals and requires where
appropriate. With the patches the tests report passing on 4.14 and

On current Debian sid it needs to read
/usr/share/dovecot/protocols.d/imapd.protocol, which is not surprising given it
already needed read access to /usr/share/dovecot/protocols.d/.
I could not find the reason why the upstream Makefile has been installing it
with permissions 555: this predates the migration from SVN.
Regardless, at least on Debian and derivatives, dh_fixperms has been
changing these permissions to 755 forever so it was causing problems,
likely we would know about it by now.
The initial motivation for this change is supporting rootless builds on Debian
and derivatives, also known as "Rules-Requires-Root: no":
- /usr/share/doc/dpkg-dev/rootless-builds.txt* on a Debian system
with a sufficiently recent dpkg-dev installed
- https://nthykier.wordpress.com/2017/10/29/building-packages-without-fakeroot/
- https://lists.debian.org/debian-devel/2017/10/msg00520.html

their debian/rules to make this work with "Rules-Requires-Root: no":

False by default for all rule types (most of them don't support the
owner conditional). Also false for non-owner FileRule.
True only for FileRule if owner=True.
Several log examples result in rules where the 'owner' conditional
should be added. With logparser.py fixed to handle owner-only events, we
need to add the owner conditional to several test_multi/*.profile files.
I verified all log files for the changed profiles and made sure that
- the log line contains fsuid= and ouid=
- fsuid == ouid
I also did a quick check on all log events containing ouid= and for
those with fsuid == ouid, I checked that the profile has the owner
conditional.

autodep() calls read_inactive_profiles() each time it's called (= for

After using "view changes", the selection got reset to the first changed

This patch ensures the selection is kept.
I propose this patch for trunk and 2.11.

I'm not sure if we should also apply this in 2.10 and 2.9 - they have
the same behaviour, but OTOH I'm not sure if changing behaviour (even if
it's an improvement) in those old releases is a good idea.
Opinions?
The last change in save_profiles() sorted() the order in which the
changed profiles get displayed. However, it did not honor the sorting
when displaying changes or saving the selected profile, leading to the
wrong profile displayed or saved.
This patch fixes picking the selected profile, and at the same time
replaces the duplicated code for doing this with a single instance.

The macro `PATH_MAX` macro is typically defined in the <limits.h>

The define `RLIMIT_OFILE` is a historic macro originating from

define, but we still assume it will always be defined in our
rlimit keywords table. Wrap it in an `ifdef` to fix compilation
on systems where it does not exist.
For the second macro `RLIMIT_RTTIME`, we do check for its
existence in our keywords table, but then forgot to do so in the
YACC rules. Wrap it into an `ifdef`, as well.

The macros __BEGIN_DECLS and __END_DECLS are not conforming to
any standard, but are a custom extension of the glibc library. As
such, it may not be available in other libc implementations, with
one example being musl libc. So compiling libapparmor won't work
with a strictly standards-conforming library.
These macros are typically used for header files which might be
included in a C++ project. Depending on whether the header is
seen by a C or C++ compiler, it will hint that functions have C
linkage. The macros themselves are rather simple:
#ifdef __cplusplus
# define __BEGIN_DECLS extern "C" {
# define __END_DECLS }
#else
# define __BEGIN_DECLS
# define __END_DECLS
#endif
To fix compilation with musl libc, simply expand those macros to
explicitly use `extern "C"`. This is already used in other parts
of apparmor and should thus be safe to use.

a testcase was added that where the expected output file did not match
the input source name, cause libapparmor's regression tests to fail:

The updated rule covers the old-style /usr/lib/firefox/firefox.sh
wrapper and the current /usr/lib/firefox{,-esr}/firefox{,-esr} paths.
It is a tiny bit wide but let's lean on the side of compatibility with
whatever similar paths are used in the future. It doesn't grant access
to anything we don't want on a current Debian sid system.

- allow reading @{PROC}/@{pid}/net/netstat and @{PROC}/@{pid}/net/snmp
- drop owner conditional - /proc/*/net/* is always owned by root, and
the owner conditional means breaking netstat for non-root users
- drop "@{PROC}/@{pids}/fd r," - /proc/*/fd is a directory, so this rule
would never apply

get_file_perms() and propose_file_rules() happily collect all file
permissions. This could lead to proposing 'wa' permissions in
aa-logprof, which then errored out because of conflicting permissions.
This patch adds a check to both functions that removes 'a' if 'w' is
present, and extends the tests to check this.
Acked-by: Seth Arnold <seth.arnold@canonical.com> for trunk and 2.11.
Note: Both functions (including this bug) were introduced together with
FileRule, so older releases are not affected.
When creating a new child profile, handle_children() did only copy over
include and path rules. While this was correct in the past, path rules
got changed to FileRule in the meantime and were therefore lost.
(In practise, this means the "$binary mr," rule wasn't added to the new
child profile, causing a "superfluous" question in aa-logprof.)
This patch changes handle_children() to carry over the complete new
child profile instead of only cherry-picking include and path rules.
Acked-by: Steve Beattie <steve@nxnw.org> for trunk and 2.11.
Older versions (with path as hasher) are not affected.

ProfileStorage __init__() to iterate over 'ruleset'.
Acked-by: Seth Arnold <seth.arnold@canonical.com>
Move ProfileStorage() from aa.py to the new profile_storage.py and make
it a class. The variable name in __init__() changes (profile -> self.data),
but the content stays the same.
The ProfileStorage class acts like a dict(), but has some additional
checks for unknown keys in place.
Also add some tests to make sure unknown keys really raise an exception.

Based on Cameron Norman's initial work
(http://bazaar.launchpad.net/~cameronnemo/apparmor/gnome-abstraction/revision/3111) with the following changes:
* don't include GTK+ 3.0 configuration: already done earlier
* generalize to future GLib versions
* support /usr/local
* allow reading the parent directory as well, following the lead
of usr.lib.telepathy: this is harmless and could be needed in some cases.

In parse_event_for_tree(), map_log_type() never gets called. Also,
aamode is never 'UNKNOWN'.
Proof for both: I have a local patch that raises an exception for both
cases since two years ;-)
This patch drops the call to map_log_type() and the function itsself.
It also adds a safety check for 'UNKNOWN' - instead of silently ignoring
it, raise an exception (which will most probably never happen).

tools.py act() is only used by aa-cleanprof, therefore the else branch
(self.name != cleanprof) never gets used.
This patch drops the dead code and renames act() to cleanprof_act() to
make it clear that only aa-cleanprof calls this function.

The JSON output is one per line, in order to differentiate between
multiple records. Each JSON record has a "dialog" entry which defines
the type of message passed. A response must contain the "dialog"
entry. "info" message does not require a response.

This patch makes the profile_storage() data structure more strict. It
- initializes everything inside a profile with proper values
- makes the profile storage a dict() instead of a hasher(), which means
it will complain loudly when trying to access non-existing elements
(hasher() was more forgiving, but this also meant hiding bugs)
The patch also fixes a minor issue related to the more strict 'repo'
profile property in serialize_profile().

(garbage) ptrace events like
... apparmor="DENIED" operation="ptrace" profile="/bin/netstat" pid=1962 comm="netstat" target=""
cause an empty name2 field, which leads to a crash in the tools.
This patch lets logparser.py ignore such garbage log events, which also
avoids the crash.
As usual, add some testcases.
test-libapparmor-test_multi.py needs some special handling to ignore the
empty name2 field in one of the testcases.

Older releases can't handle ptrace log events and therefore can't crash ;-)
The base abstraction already allows write access to
/run/systemd/journal/dev-log but journald offers both:
- a native journal API at /run/systemd/journal/socket (see sd_journal_print(4))
- /run/systemd/journal/stdout for connecting a program's output to the journal
(see systemd-cat(1)).
In addition to systemd-cat, the stdout access is required for nested container
(eg, LXD) logs to show up in the host. Interestingly, systemd-cat and LXD
containers require 'r' in addtion to 'w' to work. journald does not allow
reading log entries from this socket so the access is deemed safe.

Since r3634, the tools allow any order of dbus conditionals.
Quoting the r3634 patch description:
This patch eases the restriction on the ordering at the expense of the
utils no longer being able to detect and reject a single attribute that
is repeated multiple times. In that situation, only the last occurrence
of the attribute will be honored by the utils.
It seems nobody tested with all test profiles generated ;-) so we have to
add some exceptions to the "does not raise an exception" list now.
