Fix label for kdm
I did the chcon and rebooted. Now I see lots of:

I'm still seeing kdm mislabeled with -91, is that fix in there? I see matchpathcon /usr/bin/kdm /usr/bin/kdm system_u:object_r:xdm_exec_t:s0 selinux-policy-3.10.0-92.fc17.noarch Me too with -91. Perhaps this is because the installer image has an earlier selinux-policy and so the context isn't correct at install time? Also, what about the sys_ptrace message? I still see them with -93. Yes, this issue has been fixed in the latest policy. Which one? There will be some fixes in -94 policy selinux-policy-3.10.0-91.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report. |
