Functions implemented :
- mac_veriexec_vnode_check_unlink: Unlink on a file has been
requested and requires validation. This function prohibits the
deleting a protected file (or deleting one of these hard links, if
any).
- mac_veriexec_vnode_check_rename_from: Rename the file has been
requested and must be validated. This function controls the renaming
of protected file
- mac_veriexec_vnode_check_rename_to: File overwrite rename has been
requested and must be validated. This function prevent overwriting of
a file protected (overwriting by mv command).
The 3 fonctions together aim to control the 'removal' (via unlink) and
the 'mv' on files protected by veriexec. The intention is to reach the
functional level of NetBSD veriexec.
Add sysctl node security.mac.veriexec.unlink to toggle control on
syscall unlink.
Add tunable kernel variable security.mac.veriexec.block_unlink to toggle
unlink protection. Add the corresponding read-only sysctl.
