Hello,
I received the below SELinux message today and I am trying to figure out what caused it. I see what it says under Allow Access but I am not sure this is what I really want to do without know why it happened in the first place.
What should I be looking at to understand what or why this has happened?
Any help I would be most grateful for.
Here is the output form SELinux
SUMMARY: SELinux is preventing access to files with the label, file_t.
Detailed Description: SELinux permission checks on files labeled file_t are being denied. file_t is the context the SELinux kernel gives to files that do not have a label. This indicates a serious labeling problem. No files on an SELinux box should ever be labeled file_t. If you have just added a new disk drive to the system you can relabel it using the restorecon command. Otherwise you should relabel the entire files system.
Allowing Access: You can execute the following command as root to relabel your computer system: "touch /.autorelabel; reboot"

I'm not a pro or anything, but this bug report gives a bit more info. Have you made any changes to the disk lately?

find / -context "*:file_t:*"
The above command will show you what file is causing the messages.

Thank you for your response. I do not make changes to the disk other then software update and saving files.
I run your command above and its output is as follows:
~ $ sudo find / -context "*:file_t:*" getfilecon(/proc/29073/task/29073/fd/4): No such file or directory getfilecon(/proc/29073/task/29073/fdinfo/4): No such file or directory getfilecon(/proc/29073/fd/4): No such file or directory getfilecon(/proc/29073/fdinfo/4): No such file or directory
So it doesn't look like any files are labeled incorrectly.

That's the total output?

Yep. Nothing more. I ran it again and here is the new output:
