Actually there looks to be a second denial:
type=AVC msg=audit(1492169964.609:295): avc: denied { write } for pid=1 comm="systemd" name="db.sock" dev="tmpfs" ino=56584 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:openvswitch_var_run_t:s0 tclass=sock_file permissive=0
so my .te file now looks like:
module openvswitch-patch 1.0;
require {
type openvswitch_var_run_t;
type openvswitch_t;
type init_t;
class sock_file write;
class system module_load;
}
#============= openvswitch_t ==============
allow openvswitch_t self:system module_load;
allow init_t openvswitch_var_run_t:sock_file write;
meaning theres *two* extra lines.
This is still valid in Fedora 27, along with a new 'map' denial:
Nov 21 17:40:11 openqa.happyassassin.net audit[886]: AVC avc: denied { map } for pid=886 comm="modprobe" path="/usr/lib/modules/4.13.13-300.fc27.x86_64/modules.dep.bin" dev="dm-0" ino=201542143 scontext=system_u:system_r:openvswitch_t:s0 tcontext=system_u:object_r:modules_object_t:s0 tclass=file permissive=0
can we please get it fixed, Lukas? thanks.
note, should be fixed for *both* 26 *and* 27. This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '26'. 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 26 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 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Description of problem: systemctl start openvswitch causes an avc denial type=AVC msg=audit(1492169068.052:129): avc: denied { module_load } for pid=1939 comm="modprobe" scontext=system_u:system_r:openvswitch_t:s0 tcontext=system_u:system_r:openvswitch_t:s0 tclass=system permissiv e=0 This prevents the service loading the openvswitch.ko module Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. ensure seliinux is enforcing 2. systemctl restart openvswitch 3. Actual results: AVC denial Expected results: no AVC denial :) Additional info: running ausearch -c 'modprobe' --raw | audit2allow -M openvswitch-patch produces the following .te file: module openvswitch-patch 1.0; require { type openvswitch_t; class system module_load; } #============= openvswitch_t ============== allow openvswitch_t self:system module_load; and loading the associated .pp file then allows the openvswitch service to load the kernel module on start. This allow line probably needs adding to the selinux config
