Bug 1399758

In the end I had to create this policy module:

mitmanek:~# cat leafnode.te 

module leafnode 1.2;

require {
	type init_t;
	type unconfined_service_t;
	class tcp_socket { accept bind create getattr listen setopt };
}

#============= init_t ==============
allow init_t unconfined_service_t:tcp_socket { accept getattr };
allow init_t unconfined_service_t:tcp_socket { bind create listen setopt };
mitmanek:~#

Description of problem:
Happened during upgrade to F25

Version-Release number of selected component:
selinux-policy-3.13.1-191.14.fc24.noarch

Additional info:
reporter:       libreport-2.8.0
hashmarkername: setroubleshoot
kernel:         4.8.8-300.fc25.x86_64
type:           libreport

Description of problem:
I was trying to start tangd.socket 

reproducer:
1. dnf install tang
2. make keys
# sudo jose gen -t '{"alg":"ES256"}' -o /var/db/tang/sig.jwk

# sudo jose gen -t '{"kty":"EC","crv":"P-256","key_ops":["deriveKey"]}' \
  -o /var/db/tang/exc.jwk
3. start services
# sudo systemctl enable tangd-update.path
# sudo systemctl start tangd-update.path
# sudo systemctl enable tangd.socket
# sudo systemctl start tangd.socket

it causes fail of starting socket and selinux alert.

Just FYI, enabling tang requires just:
1. dnf install tang
2. systemctl enable --now tangd.socket

Don't bother with all those extra commands.

This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

For the record, I just hit something very similar (same?) on Fedora 27 when attempting the two-step process from comment 4: bug 1529068.
