LOGPROF.CONF(5) AppArmor LOGPROF.CONF(5)
NAME
logprof.conf - configuration file for expert options that modify the behavior of the AppArmor aa-logprof(1) program.
DESCRIPTION
The aa-logprof(1) program can be configured to have certain default behavior by the contents of logprof.conf.
The [qualifiers] section lists specific programs that should have a subset of the full ix/px/ux list when asking what mode to execute it
using.
Since creating a separate profile for /bin/bash is dangerous, we can specify that for /bin/bash, only (I)nherit, (U)nconstrained, and
(D)eny should be allowed options and only those will show up in the prompt when we're asking about adding that to a profile.
Likewise, if someone currently exec's /bin/mount in ix or px mode, things won't work, so we can provide only (U)nconstrained and (D)eny as
options.
And certain apps like grep, awk, sed, cp, and mkdir should always inherit the parent profile rather than having their own profile or
running unconfined, so for them we can specify that only (I)nherit and (D)eny are the allowed options.
Any programs that are not listed in the qualifiers section get the full (I)nherit / (P)rofile / (U)nconstrained / (D)eny option set.
If the user is doing something tricky and wants different behavior, they can tweak or remove the corresponding line in the conf file.
The [defaulthat] section lists changehat-aware programs and what hat aa-logprof(1) will collapse the entries to for that program if the
user specifies that the access should be allowed, but should not have it's own hat.
The [globs] section allows modification of the logprof rule engine with respect to globbing suggestions that the user will be prompted
with.
The format of each line is-- "<perl glob> = <apparmor glob>".
When aa-logprof(1) asks about a specific path, if the perl glob matches the path, it replaces the part of the path that matched with the
corresponding apparmor glob and adds it to the list of globbing suggestions.
Lines starting with # are comments and are ignored.
EXAMPLE
[qualifiers]
# things will very likely be painfully broken if bash has it's own profile
/bin/bash = iu
# mount doesn't work if it's confined
/bin/mount = u
# these helper utilities should inherit the parent profile and
# shouldn't have their own profiles
/bin/awk = i
/bin/grep = i
/bin/sed = i
[defaulthat]
/usr/sbin/sshd = EXEC
/usr/sbin/httpd2 = DEFAULT_URI
/usr/sbin/httpd2-prefork = DEFAULT_URI
[globs]
# /foo/bar/lib/libbaz.so -> /foo/bar/lib/lib*
/lib/lib[^/]+so[^/]*$ = /lib/lib*so*
# strip kernel version numbers from kernel module accesses
^/lib/modules/[^/]+/ = /lib/modules/*/
# strip pid numbers from /proc accesses
^/proc/d+/ = /proc/*/

NAME
aa-logprof - utility program for managing AppArmor security profiles
SYNOPSIS
aa-logprof [-d /path/to/profiles] [-f /path/to/logfile] [-m <mark in logfile>]
OPTIONS
-d --dir /path/to/profiles
The path to where the AppArmor security profiles are stored
-f --file /path/to/logfile
The path to the location of the logfile that contains AppArmor
security events.
-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's complain mode output and generate new entries for 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, (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 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 capability and path accesses.
After all of the path 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 and 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 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.
