Paul is this something we should add, or should we wait for kdbus SELInux kernel changes? The SELinux/kdbus work is still ongoing, and I'm not sure when it will land; honestly, I'm not sure when the kdbus bits will land upstream, I'm surprised Fedora has merged it for the Rawhide kernels. I would suggest just hacking away and adding whatever policy is needed for kdbus at the moment to keep the users happy, it will likely all change once we have proper SELinux access control for kdbus. Maybe we add this to dbus_system_bus_client() for now and then remove it when kdbus has proper support. Closing as WONTFIX for now because of dropped kdbus driver from Rawhide kernels. |
Description of problem: I'm not sure if it started to give this error before or after i enabled kdbus SELinux is preventing systemd-hostnam from read, write access on the file bus. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-hostnam should be allowed read write access on the bus 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: # grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_hostnamed_t:s0 Target Context system_u:object_r:kdbusfs_t:s0 Target Objects bus [ file ] Source systemd-hostnam Source Path systemd-hostnam Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-155.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.3.0-0.rc6.git2.1.fc24.x86_64 #1 SMP Thu Oct 22 16:10:20 UTC 2015 x86_64 x86_64 Alert Count 4 First Seen 2015-10-27 05:59:15 EEST Last Seen 2015-10-27 06:02:25 EEST Local ID 1440b5fd-66fd-4d49-8c12-8df45b3848b1 Raw Audit Messages type=AVC msg=audit(1445914945.90:584): avc: denied { read write } for pid=2131 comm="systemd-hostnam" name="bus" dev="kdbusfs" ino=4 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:kdbusfs_t:s0 tclass=file permissive=1 Hash: systemd-hostnam,systemd_hostnamed_t,kdbusfs_t,file,read,write Version-Release number of selected component: selinux-policy-3.13.1-155.fc24.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.3.0-0.rc6.git2.1.fc24.x86_64 type: libreport
