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 modify 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.
