[SOLVED] Devuan Beowulf: can't get rid of AppArmor

Hello:

I am in the process of building a (light as possible) Beowulf installation on a separate disk in my box.

root@devuan3:~# uname -a
Linux devuan3 4.19.0-18-amd64 #1 SMP Debian 4.19.208-1 (2021-09-29) x86_64 GNU/Linux
root@devuan3:~#

One of the things I do not want running is AppArmor.

I added the bit security=none to the kernel command line and purged it but I still get this in dmesg:

root@devuan3:~# dmesg | grep -i apparmor
[    0.328030] AppArmor: AppArmor initialized
[    0.569017] AppArmor: AppArmor Filesystem Enabled
[    1.257404] AppArmor: AppArmor sha1 policy hashing enabled
root@devuan3:~#

So I looked to see what was going on:

root@devuan3:~# apt list | grep -i installed | grep -i apparmor
--- snip ---
libapparmor1/oldstable,now 2.13.2-10 amd64 [installed,automatic]
root@devuan3:~#

AppArmor is not installed but it left behind its crap, which seems difficult to get rid of:

root@devuan3:~# apt purge libapparmor1
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dconf-service : Depends: default-dbus-session-bus but it is not installable or
                          dbus-session-bus
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
root@devuan3:~#

So what is causing this?

root@devuan3:~# aptitude why libapparmor1
i   dbus Depends libapparmor1 (>= 2.8.94)
root@devuan3:~#

dbus is installed and up to date:

root@devuan3:~# apt install dbus
Reading package lists... Done
Building dependency tree       
Reading state information... Done
dbus is already the newest version (1.12.20-0+deb10u1+devuan1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@devuan3:~#

And dbus-session-bus can't be installed:

root@devuan3:~# apt install dbus-session-bus
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'dbus-x11' instead of 'dbus-session-bus'
dbus-x11 is already the newest version (1.12.20-0+deb10u1+devuan1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@devuan3:~#

I have a faint memory of having come across this before but I cannot find it in the forum.

Any ideas?

Thanks in advance,

A.

EDIT: the AppArmor lines in dmesg are from the kernel module.

My main system is this one and as you can see it is Devuan Beowulf with a backported kernel:

groucho@devuan:~$ uname -a
Linux devuan 5.10.0-0.bpo.3-amd64 #1 SMP Debian 5.10.13-1~bpo10+1 (2021-02-11) x86_64 GNU/Linux
groucho@devuan:~$

AppArmor is not installed but like in the OP, libapparmor1 is there:

groucho@devuan:~$ apt list | grep installed | grep -i apparmor
--- snip ---
libapparmor1/oldstable,now 2.13.2-10 amd64 [installed]
groucho@devuan:~$

But with this kernel it does not make itself known via dmesg like with the Beowulf kernel.

groucho@devuan:~$ sudo dmesg | grep -i apparmor
groucho@devuan:~$

Makes me wonder why ...

Thanks for your input.

Best,

A.

Found it.
It was me bitching about AppArmor earlier this year:

https://dev1galaxy.org/viewtopic.php?id=4329

Now I have to re-check and see if it is really true that security=none disables both tomoyo and AppArmor, making apparmor=0 unneccesary.

Best,

A.

Re: [SOLVED] Devuan Beowulf: can't get rid of AppArmor

Hello:

Why is there a dbus dependency on libapparmor1?
I don't understand what is going on.

ascii w/backported kernel installation: 

groucho@devuan:~$ aptitude why libapparmor1
i   slim Depends dbus                    
i A dbus Depends libapparmor1 (>= 2.8.94)
groucho@devuan:~$

ascii VM:

groucho@dev-pihole:~$ sudo aptitude why libapparmor1
i   dbus-x11 Depends dbus                    
i A dbus     Depends libapparmor1 (>= 2.8.95)
groucho@dev-pihole:~$

chimaera VM:

root@chimaera:~# aptitude why libapparmor1
i   dbus Depends libapparmor1 (>= 2.8.94)
root@chimaera:~#

apparmor is not installed in any of these three Devuan machines.
Yet, from ascii on, there seems to be a constant apparmor infiltration.

This is the apparmor stuff I have in my main installation:

groucho@devuan:~$ uname -a

See what I am referring to?

Then there's what happens when you add apparmor=0 to the kernel command line.
Only the ascii VM reports it as being disabled:

groucho@dev-pihole:~$ sudo dmesg | grep AppArmor
[    0.286356] AppArmor: AppArmor disabled by boot time parameter
groucho@dev-pihole:~$

The chimaera VM does not:

root@chimaera:~# dmesg | grep AppArmor
root@chimaera:~#

Not does the ascii installation with the backported kernel:

groucho@devuan:~$ sudo dmesg | grep AppArmor
groucho@devuan:~$

I fail to see what an apparmor library has to do with dbus.
Or why the chimaera file system has acquired all these apparmor related files if it is not installed or has been purged.

Anyone know or have comments about this?

Thanks in advance.

Best,

A.

Because the dbus package has been built with AppArmor support enabled for architectures that support it:

https://salsa.debian.org/utopia-team/db … re.ac#L200

The AppArmor libraries won't ever be used if AppArmor is disabled so you should be able to remove them manually without breaking your system if you're that bothered by them.

I see.

Sure.
I know well enough not to muck with stuff in /etc so I will let that be for the moment.

But it isn't so much that I'm bothered by them.
I'm bothered by the fact that they are quite obviously* apparmor files and not dbus files.
* /etc/apparmor/*, /etc/apparmor.d/*, /etc/apparmor/init/*

In my "non-expert/developer/programmer" opinion, they should not be there unless apparmor is actually installed and enabled.
ie: What do I need them there for? They got there because apparmor is installed and enabled by default.

How come they are not removed/purged when apparmor is removed?

apparmor and tomoyo should not be foisted onto your installation unless you actually want to install them.

I have the idea that something is not right here.
For whatever reason it reminds me of how MS wove IE into Windows 95 so as to make it almost inoperable if it was pulled out*.
* to be able to choose an alternate browser. 

Eventually MS were found out and exposed, but by then the damage was already done.

Thanks for your input.

Best,

A.

See https://wiki.debian.org/WhereIsIt#A.22I … g_to.3F.22 to find out which package(s) own(s) those files.

Debian make several separate packages so that you can uninstall the main apparmor package without breaking the dependency chain for packages that make use of those files if AppArmor is enabled. Arch lump everything together in their apparmor package so in that distribution you *must* have the AppArmor user space utilities installed to satisfy the dependencies of any packages that are compiled with support. This is not the case in Debian, which seems like an improvement to me.

It is important to note here that the AppArmor functionality is actually provided by the kernel itself so if you really want to be rid of it you'll have to roll your own kernel with CONFIG_SECURITY_APPARMOR disabled. The apparmor package only provides the user space utilities to control the kernel space functionality.

Thanks for the link.
Quite useful.

I'm not in a situation to argue for or against.

But to me it seems like an unwarranted excess on behalf of the Debian crew.

Just like having apparmor installed and enabled by default.
Or ignoring the fact that it is disabled in the kernel command line to reinstall and enable it again when upgrading the kernel.
But Poettering seems to be in charge, so I'm not at all surprised.

My point is that if you want to install apparmor, then do it installing all the needed dependencies/utilities with it.
No need to fill up the system with files I won't be using.

It's like going to the cinema with a bathing trunk under my trousers.
Just in case I decide to go for a swim at the beach.
The nearest one being 400 km. away.

I'm quite aware of that.

Thank you very much for taking the time to explain this. 8^ )

Best,

Don't be silly. Massive, faceless, psychopathic corporate entities took control of the kernel quite some time ago.

Better?
So, if not Potty, then it is the MFPCEs but the issue (for me) stands.

ie:
You don't go to the cinema with a bathing trunk under your trousers, just in case you decide to go for a swim at the beach, 400 km. away.

Whoever decided this apparmor setup is a dick should seriously reconsider.

Thanks for taking the time to explain all this and for the humour.

Best,

A.
