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
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
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)
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
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.
