apparmor: abstract out the directory walking routine The apparmor_parser has 3 different directory walking routines. Abstract them out and use a single common routine.

libapparmor: Move over the lib functions needed by cache loading code The function names must be prepended with "_aa_" since they're going to be exported from libapparmor. The code bases using the _aa_autofree(), _aa_autoclose(), and _aa_autofclose() will need to internally alias those functions to the previously used autofree, autoclose, and autofclose names.

Unify escape sequence processing into a set of library fns. Fix the octal escape sequence that was broken, so that short escapes \0, \00 \xa, didn't work and actually resulted in some encoding bugs. Also we were missing support for the decimal # conversion \d123 Incorporate and update Steve Beattie's unit tests of escape sequences patch v2 - unify escape sequence processing, creating lib fns. - address Steve Beattie's feedback - incorporate Steve Beattie's feedback v3 - address Seth's feedback - add missing strn_escseq tests - expand strn_escseq to take a 3rd parameter to allow specifying chars to convert straight across. . eg "+" will cause it to convert \+ as + - fix libapparmor/parse.y failed escape pass through to match processunqoted Unit tests by Steve Beattie Signed-off-by: John Johansen <john.johansen@canonical.com> Acked-by: Seth Arnold <seth.arnold@canonical.com> 2014-04-15 14:59:41 -07:00

Use the gcc cleanup extension attribute to handle freeing temp allocations While some of these allocations will go away as we convert to C++, some of these need to stay C as the are going to be moved into a library to support loading cache from init daemons etc. For the bits that will eventually be C++ this helps clean things up, in the interim. TODO: apply to libapparmor as well Signed-off-by: John Johansen <john.johansen@canonical.com> 2015-03-25 17:09:26 -05:00
libapparmor: Protect _aa_autofree users from freeing bad pointers Creates a libapparmor function, _aa_asprintf(), which sets the strp to NULL on error. This is needed for all of the users of the _aa_autofree cleanup attribute because the value of strp is undefined when asprintf() fails and that could result in _aa_autofree() being passed a pointer value that it should not free.

libapparmor: Use directory file descriptor in _aa_dirat_for_each() The _aa_dirat_for_each() function used the DIR * type for its first parameter. It then switched back and forth between the directory file descriptors, retrieved with dirfd(), and directory streams, retrieved with fdopendir(), when making syscalls and calling the call back function. This patch greatly simplifies the function by simply using directory file descriptors. No functionality is lost since callers can still easily use the function after calling dirfd() to retrieve the underlying file descriptor.
