How to start svnserve.service on Fedora 18

Henrik asked:

I’m trying to start svnserve.service on Fedora 18 using:

systemctl enable svnserve.service
systemctl start svnserve.service

But I get the following error:

Feb 21 22:26:51 x.y.com svnserve[1606]: svnserve: E000013: Can't check path '/home/henrik/svn': Permission denied
Feb 21 22:26:51 x.y.com systemd[1]: svnserve.service: control process exited, code=exited status=1
Feb 21 22:26:51 x.y.com systemd[1]: Failed to start Subversion protocol daemon.
Feb 21 22:26:51 x.y.com systemd[1]: Unit svnserve.service entered failed state

But when I try to start svnserve from the command prompt it works just fine:

svnserve -d -r /home/henrik/svn

What could be the problem?

I tried to change permissions in the /home/henrik/svn cataloge but no luck…

Output from ls -ld /home/henrik/svn:

[root@speedball henrik]# ls -ld svn
drwxr-xr-x. 7 henrik henrik 4096 Feb 21 21:41 svn

Edit:

I followed Michaels advice. SELinux stops complaining about svnserve. Now the problem is that svnserve won’t start anyway, and it doesn’t give me any good fault description:

[root@speedball ~]# systemctl status svnserve.service

My answer:


We see from the audit log that SELinux denied svnserve access to traverse the /home directory, to descend into child directories. As far as I can tell, svnserve should have permission to traverse /home, so you’re likely looking at a bug. As such, you should report it on the Red Hat bugzilla.

As a workaround, while you wait for a fix, you can have svnserve run unconfined by SELinux (without disabling it system-wide). This is temporary and will be undone by a relabel or package update, so you may have to reapply it if a future update doesn’t resolve the issue.

chcon -t unconfined_exec_t $(which svnserve)
