Description Christian Schwarzgruber 2015-05-31 21:48:55 UTC
Created attachment 1033001 [details]
Bacula-fd journaltctl debug output.

Description of problem: Bacula restore job fails as bacula-fd has insufficient permissions to create files/folders etc.


Version-Release number of selected component (if applicable): 
bacula-client-5.2.13-18.fc20.x86_64 -> Needed this version as on the server runs version 5 too.

How reproducible:
Always reproducible as long as bacula-fd gets started through systemd.


Actual results:
Bacula restore job fails. 

Expected results:
Restore job does not fail.

Additional info:
When I start bacula-fd manually
$ sudo /usr/sbin/bacula-fd -f -c /etc/bacula/bacula-fd -u root -g root
restoring of the files work.

Also I want to point out that backups are ending without any error.

Comment 1 Christian Schwarzgruber 2015-05-31 22:25:56 UTC
Update:

Seems like SELinux problem. When setting SELinux policy to 'permissive' restoring of the files work.

Comment 2 Christian Schwarzgruber 2015-05-31 22:55:23 UTC
One more update:

Ok it turned out that the backup jobs are having also some permission problems.
Again, setting SELinux policy to permissive let the errors disappear.

Installed SELinux is:
selinux-policy-3.13.1-126.fc22.noarch

Here is the output of the failed files to backup, with SELinux policy set to enforce,
all three files are socket files.

```
Could not stat "/var/lib/gssproxy/default.sock": ERR=Permission denied
Could not stat "/home/cschwarzgruber/.gnupg/S.gpg-agent": ERR=Permission denied
Could not stat "/home/cschwarzgruber/.rdm": ERR=Permission denied
```

Comment 3 Simon Sekidde 2015-08-05 22:37:28 UTC
For the SELinux portion, please provide the AVCs while in permissive mode 

 # ausearch -i -m avc > ausearch.out

Comment 4 Simone Caronni 2015-12-11 11:56:24 UTC
Hello, is this still happening on Fedora 22 with the package version you specified and the latest policy?

Can you also have a try with the latest Bacula update and policy on Fedora 23?

Ahh to bad, I have already upgraded to Fedora 23.

Sorry, I can't test it with the latest Bacula version, as I use the Bacula-RPM package from Fedora 20. I had to made this decision, as Debian Jessy still uses Bacual 5, the communication between the bacula-server and bacula-fd won't work otherwise.

Enforcing

After setting policy mode to enforcing, I run a Bacula backup job, and did not get any errors.
Seems to be resolved, I will try it again with enforcing set in the config file.

Thanks,
Christian

Hey, seems to work now, I set SELinux to enforcing in the SELinux config file, rebooted, run a bacula backup job, and got no error.

Thanks again,
Christian
