Description of problem: SELinux is preventing dhclient from 'name_bind' accesses on the udp_socket port 29712. ***** Plugin bind_ports (92.2 confidence) suggests ************************ If you want to allow dhclient to bind to network port 29712 Then you need to modify the port type. Do # semanage port -a -t PORT_TYPE -p udp 29712 where PORT_TYPE is one of the following: dhcpc_port_t, isakmp_port_t. ***** Plugin catchall_boolean (7.83 confidence) suggests ****************** If you want to allow nis to enabled Then you must tell SELinux about this by enabling the 'nis_enabled' boolean. You can read 'None' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (1.41 confidence) suggests ************************** If you believe that dhclient should be allowed name_bind access on the port 29712 udp_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: # grep dhclient /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:NetworkManager_t:s0 Target Context system_u:object_r:unreserved_port_t:s0 Target Objects port 29712 [ udp_socket ] Source dhclient Source Path dhclient Port 29712 Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-158.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.8-300.fc23.x86_64 #1 SMP Tue Dec 15 16:49:06 UTC 2015 x86_64 x86_64 Alert Count 8 First Seen 2015-12-23 12:56:21 EST Last Seen 2016-01-04 10:35:50 EST Local ID 3c3d7c51-a28d-4dd0-95d0-2b32e59a81f2 Raw Audit Messages type=AVC msg=audit(1451921750.649:195): avc: denied { name_bind } for pid=1392 comm="dhclient" src=29712 scontext=system_u:system_r:NetworkManager_t:s0 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=udp_socket permissive=0 Hash: dhclient,NetworkManager_t,unreserved_port_t,udp_socket,name_bind Version-Release number of selected component: selinux-policy-3.13.1-158.fc23.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.3.5-300.fc23.x86_64 type: libreport
Do you know when this AVC occurred ?
I don't know when or why this occurred, sorry :-(
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. 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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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.
