Pull networking fixes from Jakub Kicinski:
"Networking fixes, including fixes from bpf, wireless, netfilter and
wireguard trees.

The bpf vs lockdown+audit fix is the most notable.

Things haven't slowed down just yet, both in terms of regressions in
current release and largish fixes for older code, but we usually see a
slowdown only after -rc5.

Current release - regressions:

- virtio-net: fix page faults and crashes when XDP is enabled

- mlx5e: fix HW timestamping with CQE compression, and make sure they
are only allowed to coexist with capable devices

- stmmac:
- fix kernel panic due to NULL pointer dereference of
mdio_bus_data
- fix double clk unprepare when no PHY device is connected

Current release - new code bugs:

- mt76: a few fixes for the recent MT7921 devices and runtime power
management

Previous releases - regressions:

- ice:
- track AF_XDP ZC enabled queues in bitmap to fix copy mode Tx
- fix allowing VF to request more/less queues via virtchnl
- correct supported and advertised autoneg by using PHY
capabilities
- allow all LLDP packets from PF to Tx

- kbuild: quote OBJCOPY var to avoid a pahole call break the build

Previous releases - always broken:

- bpf, lockdown, audit: fix buggy SELinux lockdown permission checks

- mt76: address the recent FragAttack vulnerabilities not covered by
generic fixes

- ipv6: fix KASAN: slab-out-of-bounds Read in
fib6_nh_flush_exceptions

- Bluetooth:
- fix the erroneous flush_work() order, to avoid double free
- use correct lock to prevent UAF of hdev object

- nfc: fix NULL ptr dereference in llcp_sock_getname() after failed
connect

- ieee802154: multiple fixes to error checking and return values

- igb: fix XDP with PTP enabled

- intel: add correct exception tracing for XDP

- tls: fix use-after-free when TLS offload device goes down and back
up

- ipvs: ignore IP_VS_SVC_F_HASHED flag when adding service

- netfilter: nft_ct: skip expectations for confirmed conntrack

- mptcp: fix falling back to TCP in presence of out of order packets
early in connection lifetime

- wireguard: switch from O(n) to a O(1) algorithm for maintaining
peers, fixing stalls and a large memory leak in the process

Misc:

- devlink: correct VIRTUAL port to not have phys_port attributes

- Bluetooth: fix VIRTIO_ID_BT assigned number

- net: return the correct errno code ENOBUF -> ENOMEM

- wireguard:
- peer: allocate in kmem_cache saving 25% on peer memory
- do not use -O3"

net/tls: Fix use-after-free after the TLS device goes down and up

When a netdev with active TLS offload goes down, tls_device_down is
called to stop the offload and tear down the TLS context. However, the
socket stays alive, and it still points to the TLS context, which is now
deallocated. If a netdev goes up, while the connection is still active,
and the data flow resumes after a number of TCP retransmissions, it will
lead to a use-after-free of the TLS context.

This commit addresses this bug by keeping the context alive until its
normal destruction, and implements the necessary fallbacks, so that the
connection can resume in software (non-offloaded) kTLS mode.

On the TX side tls_sw_fallback is used to encrypt all packets. The RX
side already has all the necessary fallbacks, because receiving
non-decrypted packets is supported. The thing needed on the RX side is
to block resync requests, which are normally produced after receiving
non-decrypted packets.

The necessary synchronization is implemented for a graceful teardown:
first the fallbacks are deployed, then the driver resources are released
(it used to be possible to have a tls_dev_resync after tls_dev_del).

A new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback
mode. It's used to skip the RX resync logic completely, as it becomes
useless, and some objects may be released (for example, resync_async,
which is allocated and freed by the driver).
