Description of problem: Package system-config-kdump is unable to get kernel informations via grubby command. Version-Release number of selected component (if applicable): selinux-policy-targeted-3.9.16-38.fc15.noarch How reproducible: 100% Steps to Reproduce: 1. start `system-config-kdump' 2. 3. Actual results: Errors and AVC deny Expected results: Additional info: Looks like grubby changed, but I'm not sure. system-config-kdump is using dbus and calls external programs (like grubby). Details from sealert: SELinux is preventing grubby from read access on the lnk_file /etc/mtab. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /etc/mtab default label should be etc_t. Then you can run restorecon. Do # /sbin/restorecon -v /etc/mtab ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that grubby should be allowed read access on the mtab lnk_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 grubby /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:kdumpgui_t:s0-s0:c0.c1023 Target Context system_u:object_r:etc_runtime_t:s0 Target Objects /etc/mtab [ lnk_file ] Source grubby Source Path grubby Port <Unknown> Host hp-xw6600-02.rhts.eng.bos.redhat.com Source RPM Packages Target RPM Packages util-linux-2.19.1-1.4.fc15 Policy RPM selinux-policy-3.9.16-38.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name hp-xw6600-02.rhts.eng.bos.redhat.com Platform Linux hp-xw6600-02.rhts.eng.bos.redhat.com 2.6.40.4-5.fc15.x86_64 #1 SMP Tue Aug 30 14:38:32 UTC 2011 x86_64 x86_64 Alert Count 1 First Seen Mon 12 Sep 2011 03:01:40 PM EDT Last Seen Mon 12 Sep 2011 03:01:40 PM EDT Local ID 547032cc-97dd-43c7-b8c9-29c0ae5b9876 Raw Audit Messages type=AVC msg=audit(1315854100.445:106): avc: denied { read } for pid=6467 comm="grubby" name="mtab" dev=dm-1 ino=2097168 scontext=system_u:system_r:kdumpgui_t:s0-s0:c0.c1023 tcontext=system_u:object_r:etc_runtime_t:s0 tclass=lnk_file Hash: grubby,kdumpgui_t,etc_runtime_t,lnk_file,read audit2allow #============= kdumpgui_t ============== allow kdumpgui_t etc_runtime_t:lnk_file read; audit2allow -R #============= kdumpgui_t ============== allow kdumpgui_t etc_runtime_t:lnk_file read;
