Does this actually causing anything to break. It looks like a leaked file descriptor. (In reply to comment #1) > Does this actually causing anything to break. It looks like a leaked file > descriptor. Not really; as far as system functionality is concerned...112 security alerts will pop up at random times when the system is running...though I do need to test whether "printing" capability is affected both locally and remote. I did read the exchange referenced in Bug 488591 and realize that this is a Vmware problem; but have not found that the Vmware folks have provided a solution. You can add a dontaudit policy to stop these avc's from happening # grep tpvmlp /var/log/audit/audit.log | audit2allow -D -M mycups # semodule -i mycups.pp (In reply to comment #3) > You can add a dontaudit policy to stop these avc's from happening > > # grep tpvmlp /var/log/audit/audit.log | audit2allow -D -M mycups > # semodule -i mycups.pp Roger...will do; thanks for the assist. Will keep fiddling with the vmware side of things to see if I can figure out a solution/work around. |
Description of problem: SELinux is preventing tpvmlp "read write" access on LCK..ttyS0 Version-Release number of selected component (if applicable): selinux-policy-3.7.19-2.fc13 How reproducible: Always upon boot/reboot Steps to Reproduce: 1. Power on or reboot system 2. Login with selinux enabled Actual results: 111 errors reference "tpvmlp" access denial Expected results: No error messages; vmware-tools ("tpvmlp) granted proper access Detailed Description & Additional Information: SELinux denied access requested by tpvmlp. It is not expected that this access is required by tpvmlp and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.
