We were not checking if the allocation failed in
backport_genl_register_family(), which could lead to NULL pointer
dereferences later. Fix that.

include/linux/rhashtable.h now uses struct lockdep_map unconditionally
which is fine for upstream as lockdep.h defines an empty lockdep_map
structure if CONFIG_LOCKDEP is not set. However, that is only true
since kernel 4.15 so adding such definition in our lockdep.h to cover
older kernels.

From: Hauke Mehrtens @ 2019-07-01 21:49 UTC (permalink / raw)
To: backports; +Cc: Johannes Berg, Hauke Mehrtens
From: Johannes Berg <johannes.berg@intel.com>
This extends the backported netlink handling with strict parsing. the
struct gen_ops now supports the validate member and does the validation
inside the backport layer.
This is needed to use backports with kernel 5.2.
[Hauke: Remove nla_validate_nested()]
[Hauke: Support struct genl_ops on older kernel versions]

ipv6_stubs.h was added in kernel commit 3616d08bcbb5 ("ipv6: Move ipv6
stubs to a separate header file").
Most of its content is from include/net/addrconf.h, so include that file
indirectly on older kernel versions.

To: backports; +Cc: Hauke Mehrtens
The brcmfmac driver now uses new sdio_retune*() functions. They are
added with kernel 5.2-rc6 and are backported to kernel 4.19.56 and
5.1.15
sdio_retune_hold_now() and sdio_retune_release() should work like in the
upstream kernel, the implementation of mmc_retune_release() and
mmc_retune_hold() was copied to backports into these functions. On
kernel < 4.3 backporting this is not so easy, so just use an empty
implementation there.
It is not possible to backport sdio_retune_crc_disable() and
sdio_retune_crc_enable() because they need an additional member in a
structure, just add an empty implementation.

mac80211_hwsim uses HRTIMER_MODE_ABS_SOFT and HRTIMER_MODE_REL_SOFT now.
These enum entries were added in commit 98ecadd4305d ("hrtimer: Add
clock bases and hrtimer mode for softirq context") in kernel 4.16.
This will execute the timers in hard interrupt context and not in soft
interrupt context like intended.

In the current kernel napi_complete_done() returns a bool and this is
now used by the mt76 driver. Try to backport this functionality by
doing the check which makes the function return false already in
backports.
This was added in upstream kernel commit 364b6055738b ("net: busy-poll:
return busypolling status to drivers")

ktime_t was converted from the union to s64 in kernel 4.10.
hrtimer_start() was already converted some time ago in backports, now
mac80211_hwsim uses hrtimer_start() together with the newly added
functions.

The behavior of of_get_mac_address() changed in kernel 5.2, it now
returns an error code and not NULL in case of an error.
This was changed in upstream kernel commit d01f449c008a
("of_net: add NVMEM support to of_get_mac_address")
