Description Lukas Slebodnik 2017-02-02 14:08:13 UTC 
Description of problem:
SELinux is preventing systemd from 'connectto' accesses on the unix_stream_socket /run/systemd/journal/stdout.

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

If you believe that systemd should be allowed connectto access on the stdout unix_stream_socket 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 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp

Comment 1 Lukas Slebodnik 2017-02-02 15:18:34 UTC 
printf 'type=AVC msg=audit(1486044204.161:366): avc:  denied  { connectto } for  pid=2846 comm="(spatcher)" path="/run/systemd/journal/stdout" scontext=system_u:system_r:init_t:s0 tcontext=system_u:system_r:kernel_t:s0 tclass=unix_stream_socket permissive=0' | audit2allow 


#============= init_t ==============

#!!!! The file '/run/systemd/journal/stdout' is mislabeled on your system.  
#!!!! Fix with $ restorecon -R -v /run/systemd/journal/stdout
allow init_t kernel_t:unix_stream_socket connectto;



But I do not think the file is mislabeled

sh$ ls -dZ /run/systemd/journal/stdout

sh$ ls -dZ /run/systemd/journal/

Comment 2 Lukas Slebodnik 2017-02-02 15:22:16 UTC 
I think it can be related to your change in selinux-policy.
https://github.com/fedora-selinux/selinux-policy/pull/184

Is it correct?
Comment 3 Zbigniew Jędrzejewski-Szmek 2017-02-02 15:53:56 UTC 
Maybe. Can you try the following patch:
https://github.com/keszybz/selinux-policy/commit/c79965b7e2e49bd63df71661a1925f6c4cc733a8 ?
