Linus,

Here are the SELinux patches for the upcoming Linux v6.18 merge window:

- Support per-file labeling for functionfs

  Both genfscon and user defined labeling methods are supported.  This
  should help users who want to provide separation between the control
  endpoint file, "ep0", and other endpoints.

- Remove our use of get_zeroed_page() in sel_read_bool()

  Update sel_read_bool() to use a four byte stack buffer instead of a
  memory page fetched via get_zeroed_page(), and fix a memory in the
  process.

  Needless to say we should have done this a long time ago, but it was
  in a very old chunk of code that "just worked" and I don't think
  anyone had taken a real look at it in many years.

- Better use of the netdev skb/sock helper functions

  Convert a sk_to_full_sk(skb->sk) into a skb_to_full_sk(skb) call.

- Remove some old, dead, and/or redundant code

Paul
