(mac80211), can and bpf (including the strncpy_from_user fix).

Current release - regressions:

- mac80211: fix memory leak of filtered powersave frames

- mac80211: free sta in sta_info_insert_finish() on errors to avoid
sleeping in atomic context

- netlabel: fix an uninitialized variable warning added in -rc4

Previous release - regressions:

- vsock: forward all packets to the host when no H2G is registered,
un-breaking AWS Nitro Enclaves

- net: Exempt multicast addresses from five-second neighbor lifetime
requirement, decreasing the chances neighbor tables fill up

- net/tls: fix corrupted data in recvmsg

- qed: fix ILT configuration of SRC block

- can: m_can: process interrupt only when not runtime suspended

Previous release - always broken:

- page_frag: Recover from memory pressure by not recycling pages
allocating from the reserves

- strncpy_from_user: Mask out bytes after NUL terminator

- ip_tunnels: Set tunnel option flag only when tunnel metadata is
present, always setting it confuses Open vSwitch

- bpf, sockmap:
- Fix partial copy_page_to_iter so progress can still be made
- Fix socket memory accounting and obeying SO_RCVBUF

- net: Have netpoll bring-up DSA management interface

- net: bridge: add missing counters to ndo_get_stats64 callback

- tcp: brr: only postpone PROBE_RTT if RTT is < current min_rtt

- enetc: Workaround MDIO register access HW bug

- net/ncsi: move netlink family registration to a subsystem init,
instead of tying it to driver probe

- net: ftgmac100: unregister NC-SI when removing driver to avoid
crash

- lan743x:
- prevent interrupt storm on open
- fix freeing skbs in the wrong context

- net/mlx5e: Fix socket refcount leak on kTLS RX resync

- net: dsa: mv88e6xxx: Avoid VLAN database corruption on 6097

- fix 21 unset return codes and other mistakes on error paths, mostly
detected by the Hulk Robot"

Merge tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:

- Add redirect_neigh() BPF packet redirect helper, allowing to limit
stack traversal in common container configs and improving TCP
back-pressure.

Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.

- Expand netlink policy support and improve policy export to user
space. (Ge)netlink core performs request validation according to
declared policies. Expand the expressiveness of those policies
(min/max length and bitmasks). Allow dumping policies for particular
commands. This is used for feature discovery by user space (instead
of kernel version parsing or trial and error).

- Support IGMPv3/MLDv2 multicast listener discovery protocols in
bridge.

- Allow more than 255 IPv4 multicast interfaces.

- Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.

- In Multi-patch TCP (MPTCP) support concurrent transmission of data on
multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.

- Support SMC-Dv2 version of SMC, which enables multi-subnet
deployments.

- Allow more calls to same peer in RxRPC.

- Support two new Controller Area Network (CAN) protocols - CAN-FD and
ISO 15765-2:2016.

- Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.

- Add TC actions for implementing MPLS L2 VPNs.

- Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary
notifications and make it easier to offload nexthops into HW by
converting to a blocking notifier.

- Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific TCP
option use.

- Reorganize TCP congestion control (CC) initialization to simplify
life of TCP CC implemented in BPF.

- Add support for shipping BPF programs with the kernel and loading
them early on boot via the User Mode Driver mechanism, hence reusing
all the user space infra we have.

- Support sleepable BPF programs, initially targeting LSM and tracing.

- Add bpf_d_path() helper for returning full path for given 'struct
path'.

- Make bpf_tail_call compatible with bpf-to-bpf calls.

- Allow BPF programs to call map_update_elem on sockmaps.

- Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).

- Support listing and getting information about bpf_links via the bpf
syscall.

- Enhance kernel interfaces around NIC firmware update. Allow
specifying overwrite mask to control if settings etc. are reset
during update; report expected max time operation may take to users;
support firmware activation without machine reboot incl. limits of
how much impact reset may have (e.g. dropping link or not).

- Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.

- Adopt or extend devlink use for debug, monitoring, fw update in many
drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
dpaa2-eth).

- In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.

- Add XDP support for Intel's igb driver.

- Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.

- Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.

- Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.

- Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.

- Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.

- Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.

- Improve performance for packets which don't require much offloads on
recent Mellanox NICs by 20% by making multiple packets share a
descriptor entry.

- Move chelsio inline crypto drivers (for TLS and IPsec) from the
crypto subtree to drivers/net. Move MDIO drivers out of the phy
directory.

- Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.

- Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

Merge branch 'udp_tunnel-convert-Intel-drivers-with-shared-tables'

Jakub Kicinski says:

====================
udp_tunnel: convert Intel drivers with shared tables

This set converts Intel drivers which have the ability to spawn
multiple netdevs, but have only one UDP tunnel port table.

Appropriate support is added to the core infra in patch 1,
followed by netdevsim support and a selftest.

The table sharing works by core attaching the same table
structure to all devices sharing the table. This means the
reference count has to accommodate potentially large values.

Once core is ready i40e and ice are converted. These are
complex drivers, but we got a tested-by from Aaron, so we
should be good :)

Compared to v1 I've made sure the selftest is executable.

Other than that patches 8 and 9 are actually from the Mellanox
conversion series were kept out to avoid Mellanox vs Intel
conflicts.

Last patch is new, some docs to let users knows ethtool
can now display UDP tunnel info.
