Description Steve Dickson 2011-08-24 20:20:56 UTC
Description of problem:
Using nfs-utils-1.2.4-7.fc16, when I start the nfs server with
the following command 'systemctl start nfs-server.service' the
following commands are logged to /var/log/messages.

rpc.nfsd[961]: rpc.nfsd: unable to bind inet TCP socket: errno 13 (Permission denied)
rpc.nfsd[961]: rpc.nfsd: unable to bind inet6 TCP socket: errno 13 (Permission denied)
rpc.nfsd[961]: rpc.nfsd: unable to set any sockets for nfsd

When I put selinux in permissive mode, the server comes up
as expected.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.systemctl start nfs-server.service

Comment 1 Miroslav Grepl 2011-08-25 09:29:01 UTC
AVC msgs would be fine.

Comment 2 Miroslav Grepl 2011-08-25 10:57:36 UTC

*** This bug has been marked as a duplicate of bug 728307 ***

Comment 3 Göran Uddeborg 2011-09-20 12:35:16 UTC
Shouldn't this have been a duplicate of bug 732968 rather than bug 728307?

Comment 4 Adam Williamson 2011-09-26 19:48:29 UTC
I'm not sure either is correct. 732968 is a different bug - Steve specifically says at the end of it that he hits an SELinux issue which he'll 'file as a separate bug', i.e., this one - and 728307 is claimed to be fixed, whereas this is still extant, I just hit it with current nfs-utils and systemd and selinux-policy.

Re-opening this bug, for now.

Comment 5 Adam Williamson 2011-09-26 19:49:53 UTC
as stated above, I can reproduce with:

[root@adam images]# rpm -q nfs-utils systemd selinux-policy-targeted

I think the system is actually booted with systemd-35-1, not 36-3, as I've been up for a while. But #728307 was claimed to be fixed in 35-1.

Comment 6 Adam Williamson 2011-09-26 19:51:01 UTC
I don't get any AVCs, in /var/log/audit.log , sealert, or /var/log/messages . But the bug definitely goes away if you do setenforce Permissive. It's trivial to reproduce - just set any valid /etc/exports , ensure nfs-utils is installed, and run 'systemctl start nfs-server.service' .

Comment 7 Göran Uddeborg 2011-09-26 20:57:54 UTC
> I'm not sure either is correct.

Um, neither am I.  I wonder what I was thinking.

I filed a bug of my own at the time, bug 739946.  Maybe I should have added the information to this one instead.

Comment 9 Miroslav Grepl 2011-09-27 13:28:06 UTC
could you test it with the latest policy. It looks ok and working.

Comment 10 Miroslav Grepl 2011-09-27 13:31:42 UTC
If it doesn't work for you, please could you test it with

# semodule -DB

Comment 11 Adam Williamson 2011-10-04 01:31:02 UTC
still doesn't work.

[root@adam adamw]# getenforce 
[root@adam adamw]# systemctl start nfs-server.service
Job failed. See system logs and 'systemctl status' for details.
[root@adam adamw]# man semodule
[root@adam adamw]# semodule -DB
[root@adam adamw]# systemctl start nfs-server.service
Job failed. See system logs and 'systemctl status' for details.
[root@adam adamw]# setenforce Permissive
[root@adam adamw]# systemctl start nfs-server.service
[root@adam adamw]# rpm -q selinux-policy

Comment 12 Miroslav Grepl 2011-10-04 05:59:28 UTC
please try to re-test it with the latest build


Comment 13 Adam Williamson 2011-10-04 20:04:31 UTC
