selinux is preveting to login after lightdm update

[Sebastien Chapuis]

Hello,
I just update lightdm from version 1.10.6 to 1.19.3 on my Fedora 24 Cinnamon.
When I try to login, I receive a message with selinux:

SELinux is preventing cinnamon-sessio from write access on the file .ICEauthority-c.

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

If you believe that cinnamon-sessio should be allowed write access on the .ICEauthority-c file 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 'cinnamon-sessio' --raw | audit2allow -M my-cinnamonsessio
# semodule -X 300 -i my-cinnamonsessio.pp

LightDM doesn't provide any SELinux rules, I suspect the correct place to fix this issue is in the cinnamon-session package in Fedora.
