Description Charles-Henri d'Adhémar 2016-11-09 21:34:34 UTC
SELinux is preventing radicale from execute access on the file /usr/bin/python3.5.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that radicale should be allowed execute access on the python3.5 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'radicale' --raw | audit2allow -M my-radicale
# semodule -X 300 -i my-radicale.pp

I was getting this on F25 with latest policy:

Removing the '-devel' packages followed by radicale service "stop" and "start" 
got rid of alerts:

Sorry, spoke too soon. Subsequent restart still trigger the alerts.

Comment 3 Juan Orti 2016-12-09 10:57:22 UTC
I'm not sure why we're getting those AVCs in F25, I'm investigating it.

It's radicale otherwise working for you?

All is working great.

Comment 9 Juan Orti 2016-12-11 14:23:42 UTC
If you still get the execute_no_trans in /usr/sbin/ldconfig, could you show me the file context of that file? It was wrong in my system, I don't know why.

# ls -lZ /usr/sbin/ldconfig
# restorecon -v /usr/sbin/ldconfig

Comment 10 Charles-Henri d'Adhémar 2016-12-11 14:48:02 UTC
Hi Juan,

Thank you very much for your support and time here.
I have to apologies, I should have tried this first myself.

Indeed restoring the context solves the issue and I have no more AVC with radicale:

# ls -lZ /usr/sbin/ldconfig
-rwxr-xr-x. 2 root root system_u:object_r:bin_t:s0 1092864 18 août  14:21 /usr/sbin/ldconfig

#  restorecon -v /usr/sbin/ldconfig
restorecon reset /usr/sbin/ldconfig context system_u:object_r:bin_t:s0->system_u:object_r:ldconfig_exec_t:s0
