8c19eb5521 dovecot auth needs to read openssl.cnf
Darix' guess is that this is needed by libpq because he uses a postgresql
database with dovecot and has ssl enabled in postgresql.

21a41deabe parser: fix equality and valgrind test scripts to use features file
Merge from trunk commit revision 2907

This patch fixes the equality test script and the valgrind wrapper
script to make the parser under test use the features.all features file
from the features_files/ subdirectory. Otherwise, the equality tests
will fail on systems where the not all of the current language features
are supported. The equality fix does so in a way to make the script work
correctly regardless of the directory it is run from.

576e8fe33b parser: fix warning in net_find_af_name
Merge from trunk commit 2906

The fix to prevent the compiler from SEGV'ing when dumping network
rules in commit 2888 introduced the following compiler warning:

  network.c: In function ‘const char* net_find_af_name(unsigned int)’:
  network.c:331:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
    for (i = 0; i < sizeof(network_mappings) / sizeof(*network_mappings); i++) {

The problem is that the counter i is an int, but sizeof returns size_t
which is unsigned. The following patch fixes the issue by converting the
type of i to size_t.

05ab11fec4 Fix compilation of audit modifiers
cherry-pick: -r2901

This fixes the incorrect compilation of audit modifiers for exec and
pivot_root as detailed in

https://launchpad.net/bugs/1431717
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
  set.

2d7ba0871f Split off serialize_parse_profile_start_line() from
serialize_profile_from_old_profile() in aa.py, as a preparation to add
tests and then switch to the upcoming RE_PROFILE_START wrapper function.

Besides moving the code, I replaced write_prof_data[profile][hat]['profile']
and write_prof_data[profile][hat]['external'] with function parameters
to avoid that I have to pass around the full write_prof_data.

Note: The "lineno" parameter is technically superfluous - I kept it to
have the parameters as close to parse_profile_start() as possible and
hope that I can merge those functions later (when we have test coverage).

70dc81c4fd merge 'path' if conditions in logparser.py / add_event_to_tree()
logparser.py / add_event_to_tree() has 5 places to handle 'path' events.
This patch merges most if conditions to reduce that to 2 places.

It also makes the matching a bit more strict - instead of using 'in',
'xattr' has to be an exact match and 'file_' is matched with startswith().

Also, 'getattr' is added to the list of file events.

321a2c1dcb regression tests: fix gcc-5 inline confusion
Merge from trunk revision 2889

Parts of the regression tests that use the do_open() inline function
from changehat.h fail to build under gcc-5 like so:

  cc -g -O0 -Wall -Wstrict-prototypes    changeprofile.c  -lapparmor -o changeprofile /tmp/ccT6GE6k.o: In function `main':
    /home/ubuntu/bzr/apparmor/tests/regression/apparmor/changeprofile.c:43: undefined reference to `do_open'
    collect2: error: ld returned 1 exit status
    <builtin>: recipe for target 'changeprofile' failed

This patch converts the do_open function declaration to be static
inline, which apparently keeps gcc-5 from getting confused.

735ef5d32b utils/aa-status: don't crash when non-ASCII mountpoints are in use
Merge from trunk revision 2892

aa-status was crashing when parsing through /proc/mounts looking
to see if and where the securityfs synthetic file system is mounted
if there was a mount point that contained characters outside of the
charset in use in the environment of aa-status. This patch fixes the
issue by converting the read of /proc/mounts into a binary read and
then uses decode on the elements.

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.

586222c94e move strip_quotes() from aa.py to regex.py
The upcoming function parse_profile_start() (which is a wrapper around
the updated RE_PROFILE_START, and will live in regex.py) needs
strip_profile(), but importing it from aa.py fails with an import loop.
Therefore this patch moves strip_quotes() from aa.py to regex.py and
re-imports it into aa.py.

As a bonus, the patch also adds some tests for strip_quotes() ;-)


Also add TestStripQuotes to the test_suite list because it won't run
otherwise.

df099620dd aa.py: split off parse_profile_start() from parse_profile_data() and add tests
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

The patch also adds some tests for the parse_profile_start() function.

Also adds a check to get_profile_flags() to catch an invalid syntax:
    /foo (  ) {
was accepted by get_profile_flags, while
    /foo () {

When testing with the parser, both result in a syntax error, therefore

cf4afcb860 parser: Fix return value of dirat_for_each()
Seth pointed out that dirat_for_each() didn't correctly handle the
return value from readdir_r(). On error, it directly returns a positive
errno value. This would have resulted in that positive errno value being
returned, with an undefined errno value set, from dirat_for_each().
However, the dirat_for_each() documentation states that -1 is returned,
with errno set, on error.

This patch results in readdir_r()'s return value being handled
appropriately. In addition, it ensures that 0 is always returned on
success.
