Hello Doncho,

Can you check if the following local module is sufficient?

f38# cat local_blueman.cil
(allow blueman_t gconf_home_t (lnk_file (read)))
f38# semodule -i local_blueman.cil

Added the module:
semodule -l | grep ^local_

SIGUSR1 to auditd (rotate logs)


cat /var/log/audit/audit.log | grep blueman

#============= blueman_t ==============
allow blueman_t gconf_home_t:file { getattr ioctl open read };
allow blueman_t user_home_t:dir read;


The following "fixes" things:

cat local_blueman2.te 

module local_blueman2 1.0;

require {
        type blueman_t;
        type user_home_t;
        type gconf_home_t;
        class lnk_file read;
        class file { getattr ioctl open read };
        class dir read;
}

#============= blueman_t ==============
allow blueman_t gconf_home_t:file { getattr ioctl open read };
allow blueman_t gconf_home_t:lnk_file read;
allow blueman_t user_home_t:dir read;

Thank you. This line though seems to be unclear: what is location of the src directory and what is its label?

type=AVC msg=audit(1680183089.658:1221): avc:  denied  { read } for  pid=52308 comm="blueman-mechani" name="src" dev="dm-0" ino=693440 scontext=system_u:system_r:blueman_t:s0 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=dir permissive=1

ls -lZd `find /home -inum 693440`

Anyway, after rereading the bz it seems like a result of custom software installation which also needs to be taken care by the system administrator.

Interesting, this is

drwxrwxr-x. 1 dgunchev dgunchev unconfined_u:object_r:user_home_t:s0 126 2022-11-28 12:20 /home/dgunchev/git/conductor/schedule/src

I can see how it got there: cat /home/dgunchev/.local/lib/python3.11/site-packages/easy-install.pth
/home/dgunchev/git/conductor/schedule/src
/home/dgunchev/git/conductor/common/src

and here is how it got there:

pip3 install --upgrade-strategy=only-if-needed --user -e .

This is actually an attempt for faster python development :-) Blueman definitely needs no access there, I tried /usr/bin/python3 -I /usr/bin/blueman-applet but that does not remove ~/.local/lib/python* form sys.path, and the only solution I can think of is to modify blueman to filter sys.path :-( even ChatGPT agrees.

I know why '-I' did not work, I had to add it to all files including libexec:

$ rpm -ql blueman | grep '/usr/\(bin\|libexec\)/'
/usr/bin/blueman-adapters
/usr/bin/blueman-applet
/usr/bin/blueman-manager
/usr/bin/blueman-sendto
/usr/bin/blueman-services
/usr/bin/blueman-tray
/usr/libexec/blueman-mechanism
/usr/libexec/blueman-rfcomm-watcher

Adding -I to the shebang fixes the issue. So this is not SELinux but rather python packaging problem? Maybe a guideline on all python packages to add '-I' or at least '-s'?

Frankly I don't know. You may try to report it in the appropriate place.
If no new information appears, I'll close this bz.

Thank you, this bug should be closed - not SELinux issue for sure.

What would be the appropriate place to report? I can update the blueman spec file to incorporate that change but this should affect any python script ... start with blueman and see ask there?

I think I found my answer. 

$ head /usr/sbin/tuned
#!/usr/libexec/platform-python -Es

So in short this is Blueman packaging bug. Please close.

Closing per the last comment, thanks Doncho for digging deep.
