If you re-enabled SELinux please, fix labels on your system. # restorecon -R -v / |
Description of problem: I was doing nothing special. I enabled SELINUX lately and I saw the side effect that KDM offers a different default than it used to (plasma) when SELINUX was disabled. This might be the reason. SELinux is preventing /usr/bin/kdm from 'write' accesses on the file .dmrc. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that kdm should be allowed write access on the .dmrc 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 kdm /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:svirt_sandbox_file_t:s0 Target Objects .dmrc [ file ] Source kdm Source Path /usr/bin/kdm Port <Unknown> Host (removed) Source RPM Packages kdm-4.11.22-2.fc23.x86_64 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 9 First Seen 2016-01-07 08:11:36 CET Last Seen 2016-01-08 00:28:16 CET Local ID 1465764b-3f59-4846-9467-e457588b46a3 Raw Audit Messages type=AVC msg=audit(1452209296.647:298): avc: denied { write } for pid=9065 comm="kdm" name=".dmrc" dev="dm-7" ino=18087947 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:svirt_sandbox_file_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1452209296.647:298): arch=x86_64 syscall=open success=no exit=EACCES a0=565183721e12 a1=a41 a2=180 a3=12 items=0 ppid=8940 pid=9065 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 tty=(none) ses=3 comm=kdm exe=/usr/bin/kdm subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: kdm,xdm_t,svirt_sandbox_file_t,file,write Version-Release number of selected component: selinux-policy-3.13.1-158.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.8-300.fc23.x86_64 type: libreport
