Re: difference between setfiles and restorecon

Vit,

Thanks for the links.
I can use restorecon to recover to default value if file content is changed by the chcon command.
But setfiles does nothing when the file is changed by chcon.

May I change something and let setfiles recover it?

Hi,
let me walk you through the steps to find this info on your own.

# dnf provides setfiles
policycoreutils-3.3-4.fc36.x86_64 : SELinux policy core utilities
# dnf provides restorecon
policycoreutils-3.3-4.fc36.x86_64 : SELinux policy core utilities

So both utilities are shipped as part of policycoreutils package.
The package is build from the following repository:
https://src.fedoraproject.org/rpms/policycoreutils
The spec file
(https://src.fedoraproject.org/rpms/policycoreutils/blob/rawhide/f/policycoreutils.spec#_18)
shows that the source code repository is
https://github.com/SELinuxProject/selinux

$ git clone https://github.com/SELinuxProject/selinux ; cd selinux
$ find -name setfiles.c
./policycoreutils/setfiles/setfiles.c

This is actually the source file for both tools. Their behavior changes
based on the executable name
https://github.com/SELinuxProject/selinux/blob/main/policycoreutils/setfiles/setfiles.c#L178

Hope this helps,
Vit
