Hello,
AFAIK the YaST AppArmor module uses the JSON output of aa-status.
There are two upcoming changes, and I'd like to point them out so that
you can adjust the YaST AppArmor module if needed.
a) new profile modes
Besides complain and enforce mode, future AppArmor versions (>= 3.0)
will also have `unconfined`, `mixed` and `kill`.
Technically the structure of the JSON doesn't change, but there will be
new values for the status, for example
"processes": {
"/usr/lib/GConf/2/gconfd-2": [
{
"pid": "3899",
"profile": "/usr/lib/GConf/2/gconfd-2",
"status": "kill"
}
]
}
"profiles": {
"/does/not/exist": "kill"
}
Side question: Do you think this warrants increasing the JSON version
number?
Quick explanation about the new modes:
- unconfined: similar to not having a profile, but when using an
unconfined profile, it's possible to replace it with a "real" profile
later, so that programs initially running under an unconfined profile
get a profile in enforce mode
- kill: similar to enforce, but on profile violations, the process will
be killed instead of "just" getting EPERM
- mixed: when using stacked profiles, this indicates that a program is
for example using a stack of two profiles, one in complain and one in
enforce mode. (This also means you'll see "mixed" only in aa-status
output, but never in a profile's "flags=(...)".)
(Extending the aa-* tools to support switching to kill and unconfined
mode is still on my TODO list.)
b) whitespace changes
aa-status was rewritten to C, which results in changed whitespace in the
--json output. Currently --pretty-json also results in "compressed"
JSON, but I hope that this will change again in the future.
I'd guess/hope that whitespace changes shouldn't matter, but please
check nevertheless.
Currently the new aa-status is only available in upstream git master.
If it makes testing easier for you, I can provide the compiled binary or
some example output.
Regards,
Christian Boltz
