Looks like somehow .dmrc file got created with the wrong label. restorecon -R -v ~/.dmrc* Any idea why this got create with the wrong label? What is the path to your homedir and what is its label? ls -lZd ~/ # ls -lZd . .dmrc* drwxr-xr-x. eblake eblake unconfined_u:object_r:user_home_t:s0 . -rw-r--r--. eblake eblake system_u:object_r:user_home_t:s0 .dmrc # pwd /home/remote/eblake # cat /etc/selinux/targeted/contexts/files/file_contexts.subs /home /home/remote/ # matchpathcon /home/remote/eblake/.dmrc* /home/remote/eblake/.dmrc unconfined_u:object_r:user_home_t:s0 On further investigation, I'm wondering if I'm the victim of previous bad advice in bug 626258; because when I tried: # semanage fcontext -a -e /home /home/remote it swaps the order of the entries in /etc/selinux/targeted/contexts/files/file_contexts.subs. Yes, # semanage fcontext -a -e /home /home/remote is the correct command in this case. *** Bug 976997 has been marked as a duplicate of this bug. *** |
SELinux is preventing /usr/libexec/gdm-session-worker from 'create' accesses on the file .dmrc.Q2X3PV. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that gdm-session-worker should be allowed create access on the .dmrc.Q2X3PV 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 gdm-session-wor /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:user_home_t:s0 Target Objects .dmrc.Q2X3PV [ file ] Source gdm-session-wor Source Path /usr/libexec/gdm-session-worker Port <Unknown> Host (removed) Source RPM Packages gdm-2.32.0-1.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-25.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.35.10-74.fc14.x86_64 #1 SMP Thu Dec 23 16:04:50 UTC 2010 x86_64 x86_64 Alert Count 2 First Seen Sat 29 Jan 2011 09:29:48 PM MST Last Seen Sat 29 Jan 2011 09:35:56 PM MST Local ID b3cb8fb1-5ecf-4625-89a5-6c32e66dcc94 Raw Audit Messages type=AVC msg=audit(1296362156.124:24): avc: denied { create } for pid=2515 comm="gdm-session-wor" name=".dmrc.Q2X3PV" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:user_home_t:s0 tclass=file type=SYSCALL msg=audit(1296362156.124:24): arch=x86_64 syscall=open success=no exit=EACCES a0=1bc8850 a1=c2 a2=1b6 a3=5858585858582e63 items=0 ppid=2491 pid=2515 auid=14986 uid=14986 gid=14986 euid=14986 suid=14986 fsuid=14986 egid=14986 sgid=14986 fsgid=14986 tty=(none) ses=1 comm=gdm-session-wor exe=/usr/libexec/gdm-session-worker subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: gdm-session-wor,xdm_t,user_home_t,file,create audit2allow #============= xdm_t ============== allow xdm_t user_home_t:file create; audit2allow -R #============= xdm_t ============== allow xdm_t user_home_t:file create;
