From: Arnd Bergmann <arnd@arndb.de>
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

Miller, Arnd Bergmann, Kalle Valo, linux-wireless From: Arnd Bergmann <arnd@arndb.de> The airo driver overloads SIOCDEVPRIVATE ioctls with another set based on SIOCIWFIRSTPRIV. Only the first ones actually work (also in compat mode) as the others do not get passed down any more. Change it over to ndo_siocdevprivate for clarification.
