Description of problem: Setroubleshoot reported the following AVC: type=AVC msg=audit(1333912858.743:429): avc: denied { execmod } for pid=7118 comm="npviewer.bin" path="/usr/lib/nvidia/libnvidia-glcore.so.290.10" dev="sda2" ino=3926043 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lib_t:s0 tclass=file Setroubleshoot suggests changing the context to textrel_shlib_t. I believe that used to be the default, and there are still file context rules in the policy intended to give them that context. But they are overridden by the default rule for the entire /usr/lib tree. The Nvidia patterns have regular expressions that start earlier in the path than the default rule, which I guess is the reason this happens. freddi$ findcon /etc/selinux/targeted/contexts/files/file_contexts -p /usr/lib/nvidia/libnvidia-glcore.so.290.10 /.* system_u:object_r:default_t:s0 /usr/.* system_u:object_r:usr_t:s0 /usr/(.*/)?lib(/.*)? system_u:object_r:lib_t:s0 /usr/(local/)?.*\.so(\.[^/]*)* -- system_u:object_r:lib_t:s0 /usr/(.*/)?nvidia/.+\.so(\..*)? -- system_u:object_r:textrel_shlib_t:s0 /usr/(.*/)?lib(/.*)?/nvidia/.+\.so(\..*)? -- system_u:object_r:textrel_shlib_t:s0 /usr/lib(/.*)?/nvidia/.+\.so(\..*)? -- system_u:object_r:textrel_shlib_t:s0 /usr/lib(/.*)?/libnvidia.+\.so(\.[^/]*)* -- system_u:object_r:textrel_shlib_t:s0 /usr/lib/.* system_u:object_r:lib_t:s0 Version-Release number of selected component (if applicable): selinux-policy-targeted-3.10.0-110.fc17.noarch How reproducible: It is persistent. Changing the contexts to something else and running restorecon on one of the files puts it back to lib_t. Steps to Reproduce: 1. Install nvidia libraries in /usr/lib/nvidia 2. Run restorecon on the files in the directory Actual results: freddi$ ll -Z /usr/lib/nvidia/libnvidia-glcore.so.290.10 -rwxr-xr-x. root root system_u:object_r:lib_t:SystemLow /usr/lib/nvidia/libnvidia-glcore.so.290.10 Expected results: freddi$ ll -Z /usr/lib/nvidia/libnvidia-glcore.so.290.10 -rwxr-xr-x. root root system_u:object_r:textrel_shlib_t:SystemLow /usr/lib/nvidia/libnvidia-glcore.so.290.10
