AA-LOGPROF(8)                      AppArmor                      AA-LOGPROF(8)

NAME
       aa-logprof - utility for updating AppArmor security profiles

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

OPTIONS
       -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:
                        /var/log/audit/audit.log
                        /var/log/syslog
                        /var/log/messages

        -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.

DESCRIPTION
       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
       (D)eny.

       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.
