I'm seeing the same thing here. I run a small local socket activated service, which worked fine but can't be started at all under F24:

I should add that this happens with selinux-policy-3.13.1-191.10.fc24.noarch, -191.11 and -191.12 (downloaded from Koji this morning). policy_module(myinit, 1.0) gen_require(` attribute domain type init_t; ') allow init_t domain:tcp_socket create_stream_socket_perms; Lukas we should have a rule like this or maybe allow init_t daemon:tcp_socket create_stream_socket_perms; I guess we already have allow init_t daemon:tcp_socket create_stream_socket_perms; So we need to make these other domains daemons. I have created https://github.com/fedora-selinux/selinux-policy/pull/146 To fix these issues. Just so you know, that PR didn't seem to fix the issue for me. I'm using the following, which fixes my local unconfined daemon but needs to be extended to cover rsync and probably a number of other daemons.

Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '24'. 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 24 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. Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
