aa-logprof - utility for updating AppArmor security profiles


   aa-logprof [-d  /path/to/profiles] [-f /path/to/logfile] [-m <mark in


   -d --dir   /path/to/profiles

      Specifies where to look for the AppArmor security profile set.
      Defaults to /etc/apparmor.d.

   -f --file   /path/to/logfile

       Specifies the location of logfile that contains AppArmor security events.
           Default locations are read from F</etc/apparmor/logprof.conf>.
           Typical defaults are:

    -m --logmark    "mark"

      aa-logprof will ignore all events in the system log before the
      specified mark is seen.  If the mark contains spaces, it must
      be surrounded with quotes to work correctly.


   aa-logprof is an interactive tool used to review AppArmor generated
   messages and update AppArmor security profiles.

   Running aa-logprof will scan the log file and if there are new AppArmor
   events that are not covered by the existing profile set, the user will
   be prompted with suggested modifications to augment the profile.

   When aa-logprof exits profile changes are saved to disk.  If AppArmor
   is running, the updated profiles are reloaded and if any processes that
   generated AppArmor events are still running in the null-complain-
   profile, those processes are set to run under their proper profiles.

   Responding to AppArmor Events
   aa-logprof will generate a list of suggested profile changes that the
   user can choose from, or they can create their own, to modifiy the
   permission set of the profile so that the generated access violation
   will not re-occur.

   The user is then presented with info about the access including
   profile, path, old mode if there was a previous entry in the profile
   for this path, new mode, the suggestion list, and given these options:

      (A)llow, (D)eny, (I)gnore, (N)ew, (G)lob last piece, (Q)uit

   If the AppArmor profile was in complain mode when the event was
   generated, the default for this option is (A)llow, otherwise, it's

   The (D)eny option adds a "deny" rule to the AppArmor profile, which
   silences logging.

   The (I)gnore option allows user to ignore the event, without making any
   changes to the AppArmor profile.

   The suggestion list is presented as a numbered list with includes at
   the top, the literal path in the middle, and the suggested globs at the
   bottom.  If any globs are being suggested, the shortest glob is the
   selected option, otherwise, the literal path is selected.  Picking
   includes from the list must be done manually.

   Hitting a numbered key will change the selected option to the
   corresponding numbered entry in the list.

   If the user selects (N)ew, they'll be prompted to enter their own
   globbed entry to match the path.  If the user-entered glob does not
   match the path for this event, they'll be informed and have the option
   to fix it.

   If the user selects (G)lob last piece then, taking the currently
   selected option, aa-logprof will remove the last path element and
   replace it with /*.

   If the last path element already was /*, aa-logprof will go up a
   directory level and replace it with /**.

   This new globbed entry is then added to the suggestion list and marked
   as the selected option.

   So /usr/share/themes/foo/bar/baz.gif can be turned into
   /usr/share/themes/** by hitting "g" three times.

   If the user selects (A)llow, aa-logprof will take the current selection
   and add it to the profile, deleting other entries in the profile that
   are matched by the new entry.

   Adding r access to /usr/share/themes/** would delete an entry for r
   access to /usr/share/themes/foo/*.gif if it exists in the profile.

   If (Q)uit is selected at this point, aa-logprof will ignore all new
   pending accesses.

   After all of the accesses have been handled, logrof will write all
   updated profiles to the disk and reload them if AppArmor is running.

   New Process (Execution) Events
   If there are unhandled x accesses generated by the execve(2) of a new
   process, aa-logprof will display the parent profile and the target
   program that's being executed and prompt the user to select an execute
   modifier. These modifiers will allow a choice for the target to: have
   it's own profile (px), inherit the parent's profile (ix), run
   unconstrained (ux), or deny access for the target. See apparmor.d(5)
   for details.

   If there is a corresponding entry for the target in the qualifiers
   section of /etc/apparmor/logprof.conf, the presented list will contain
   only the allowed modes.

   The default option for this question is selected using this logic--
     # if px mode is allowed and profile exists for the target
     #   px is default.
     # else if ix mode is allowed
     #   ix is default
     # else
     #   deny is default

   aa-logprof will never suggest "ux" as the default.

   ChangeHat Events
   If unknown aa_change_hat(2) events are found, the user is prompted to
   add a new hat, if the events should go into the default hat for this
   profile based on the corresponding entry in the defaulthat section of
   logprof.conf, or if the following events that run under that hat should
   be denied altogether.

   Capability Events
   If there are capability accesses, the user is shown each capability
   access and asked if the capability should be allowed, denied, or if the
   user wants to quit. See capability(7) for details.
