Merge branch 'ndo_ioctl-rework'

Arnd Bergmann says:

====================
ndo_ioctl rework

This series is a follow-up to the series for removing
compat_alloc_user_space() and copy_in_user() that has now
been merged.

I wanted to be sure I address all the ways that 'struct ifreq' is used
in device drivers through .ndo_do_ioctl, originally to prove that
my approach of changing the struct definition was correct, but then
I discarded that approach and went on anyway.

Roughly, the contents here are:

- split out all the users of SIOCDEVPRIVATE ioctls into a
separate ndo_siocdevprivate callback, to better see what
gets used where

- fix compat handling for those drivers that pass data
directly inside of 'ifreq' rather than using an indirect
ifr_data pointer

- remove unreachable code in ndo_ioctl handlers that relies
on command codes we never pass into that, in particular
for wireless drivers

- split out the ethernet specific ioctls into yet another
ndo_eth_ioctl callback, as these are by far the most
common use of ndo_do_ioctl today. I considered splitting
them further into MII and timestamp controls, but
went with the simpler change for now.

- split out bonding and wandev ioctls into separate helpers

- rework the bridge handling with a separate callback

At this point, only a few oddball things remain in ndo_do_ioctl:
appletalk and ieee802154 pass down SIOCSIFADDR/SIOCGIFADDR and
some wireless drivers have completely dead code.

I have thoroughly compile tested this on randconfig builds,
but not done any notable runtime testing, so please review.
All of it is also available as part of a larger branch at

https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git \
compat-alloc-user-space-12

Changes since v2:
- rebase to net-next
- fix qeth regression
- Cc driver maintainers for each patch and in cover letter

Changes since v1:

- rebase to linux-5.14-rc2
- add conversion for ndo_siowandev, bridge and bonding drivers
- leave broken wifi drivers untouched for now

dev_ioctl: split out ndo_eth_ioctl

Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.

Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

This is a purely cosmetic change intended to help readers find
their way through the implementation.

Merge tag 'net-next-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- BPF:
- add syscall program type and libbpf support for generating
instructions and bindings for in-kernel BPF loaders (BPF loaders
for BPF), this is a stepping stone for signed BPF programs
- infrastructure to migrate TCP child sockets from one listener to
another in the same reuseport group/map to improve flexibility
of service hand-off/restart
- add broadcast support to XDP redirect

- allow bypass of the lockless qdisc to improving performance (for
pktgen: +23% with one thread, +44% with 2 threads)

- add a simpler version of "DO_ONCE()" which does not require jump
labels, intended for slow-path usage

- virtio/vsock: introduce SOCK_SEQPACKET support

- add getsocketopt to retrieve netns cookie

- ip: treat lowest address of a IPv4 subnet as ordinary unicast
address allowing reclaiming of precious IPv4 addresses

- ipv6: use prandom_u32() for ID generation

- ip: add support for more flexible field selection for hashing
across multi-path routes (w/ offload to mlxsw)

- icmp: add support for extended RFC 8335 PROBE (ping)

- seg6: add support for SRv6 End.DT46 behavior

- mptcp:

- aggregation handling improvements for some drivers
- minstrel improvements for no-ack frames
- deferred rate control for TXQs to improve reaction times
- switch from round robin to virtual time-based airtime scheduler

- add trace points:
- tcp checksum errors
- openvswitch - action execution, upcalls
- socket errors via sk_error_report

Device APIs:

- devlink: add rate API for hierarchical control of max egress rate
of virtual devices (VFs, SFs etc.)
