Ejabberd is supposed to expire files when they are older than desired, and selinux prevents it. How can I solve this problem other than by disabling selinux or by deleting the files manually?
It’s possible that you are only capturing part of the process, such as a stat() before unlink(), so it still fails. You need to capture the entire process.
Temporarily set it to permissive (setenforce Permissive) and let it do what it does (is there a way to force it?). Then you should use ausearch to find the AVCs over the time period when it ran, and pipe that into audit2allow.
Hm, yes, thanks, I tried that ... Now I used ausearch -p to search by pid, and I might have found it. A selinux module was created with the output which would allow ejabberd to unlink files and directories of the appropriate type, and I installed that.
I thought ejabberd deletes the files when restarting, but apparently it doesn't, so I'll have to watch for it in the log file.
HOWEVER...
There’s probably a better solution than blindly creating a module. You need to figure out what the correct SELinux attribute to put on the directory so you don’t need a module.
Yes, I did that. Perhaps the selinux permissions ejabberd is being installed with are incomplete.
