Linus Torvalds 91ec203513 Networking changes for 7.3.
Core & protocols
 ----------------
 
  - A few steps lowering rtnl_lock dependence:
    - per-netns netdev unregistration for select SW drivers
      (e.g. veth, ipvlan, tunnels)
    - rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE)
    - prepare software drivers and TC qdiscs for rtnl_lock-less GET
 
  - Support BIG TCP (>64kB TSO) in UDP tunnels (vxlan, geneve).
 
  - Support buffers larger than PAGE_SIZE in devmem zero-copy API.
 
  - Improve MPTCP handling of extreme memory pressure handling,
    when out-of-order queue had to be pruned.
 
  - Report the per-group user count via RTM_GETMULTICAST.
 
  - Expose the route deletion reason in RTM_DELROUTE.
 
  - Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful
    handling of LSM denials when receiving SCM_RIGHTS messages: instead
    of truncating the message at the first blocked fd, keep every fd slot
    and store the LSM errno in the blocked slot.
 
  - IPv6 Segment Routing - support looking up the post-encap SID
    (address) in a different/specified routing table.
 
  - Support PRP RedBox (interlink) creation.
 
  - Support per-nexthop UDP dst port in VXLAN.
 
  - Continue converting getsockopt callbacks in a number of protocols
    to iov_iter.

Merge tag 'net-next-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
 "One of the 'small improvements all over the place' releases for us.

  It's hard to draw any direct comparisons because summer vacations
  disrupted our patch processing (and presumably - generation) quite a
  bit.

  Quick and dirty count suggests we (Paolo and I) merged a very similar
  number of net (632) and net-next (648) patches. This is not telling
  the full story either because 1/3 to 1/2 of the net-next patches also
  *seem* like AI-driven low priority fixes, cleanups and clarifications.

  We are completely overwhelmed, of course. The glimmer of hope is that
  we secured sufficient LLM budget and access (thank you Meta!) to run
  reviews with multiple frontier models on each patch. This eliminates
  some hallucinations. That said, in terms of review, the LLMs can only
  do so much.

  The sad truth is that our APIs (especially for rare events like PCIe
  errors, timeouts etc) have always been racy, and now LLMs don't let us
  ignore that. I expect our direction for the next release will be to
  tweak the reviews a little bit more, but start shifting focus to
  letting the LLMs take care of the busy work - managing patchwork,
  automating common process complaints, editing commit messages, and
  maybe applying patches which already got "reviewed-by" tags from
  people we trust...
