      net: prefer socket bound to interface when not in VRF · 8d6c414c
      Mike Manning authored 
      The commit 6da5b0f0 ("net: ensure unbound datagram socket to be
chosen when not in a VRF") modified compute_score() so that a device
match is always made, not just in the case of an l3mdev skb, then
increments the score also for unbound sockets. This ensures that
sockets bound to an l3mdev are never selected when not in a VRF.
But as unbound and bound sockets are now scored equally, this results
in the last opened socket being selected if there are matches in the
default VRF for an unbound socket and a socket bound to a dev that is
not an l3mdev. However, handling prior to this commit was to always
select the bound socket in this case. Reinstate this handling by
incrementing the score only for bound sockets. The required isolation
due to choosing between an unbound socket and a socket bound to an
l3mdev remains in place due to the device match always being made.
The same approach is taken for compute_score() for stream sockets.

1) Fix ARM BPF JIT to preserve caller-saved regs for DIV/MOD JIT-internal
   helper call, from Johan Almbladh.

2) Fix integer overflow in BPF stack map element size calculation when
   used with preallocation, from Tatsuhiko Yasumatsu.

3) Fix an AF_UNIX regression due to added BPF sockmap support related
   to shutdown handling, from Jiang Wang.

4) Fix a segfault in libbpf when generating light skeletons from objects
   without BTF, from Kumar Kartikeya Dwivedi.

5) Fix a libbpf memory leak in strset to free the actual struct strset
   itself, from Andrii Nakryiko.

6) Dual-license bpf_insn.h similarly as we did for libbpf and bpftool,
   with ACKs from all contributors, from Luca Boccassi.

====================
wireless-drivers-next patches for v5.16

First set of patches for v5.16. ath11k getting most of new features
this time. Other drivers also have few new features, and of course the
usual set of fixes and cleanups all over.

Major changes:

rtw88

* support adaptivity for ETSI/JP DFS region

* 8821c: support RFE type4 wifi NIC

brcmfmac

* DMI nvram filename quirk for Cyberbook T116 tablet

ath9k

* load calibration data and pci init values via nvmem subsystem

ath11k

* include channel rx and tx time in survey dump statistics

* support for setting fixed Wi-Fi 6 rates from user space

* support for 80P80 and 160 MHz bandwidths

* spectral scan support for QCN9074

* support for calibration data files per radio

* support for calibration data via eeprom

* support for rx decapsulation offload (data frames in 802.3 format)

* support channel 2 in 6 GHz band

ath10k

* include frame time stamp in beacon and probe response frames

wcn36xx

* enable Idle Mode Power Save (IMPS) to reduce power consumption during idle

====================
net: add a helpers for loading netdev->dev_addr from FW

We're trying to make all writes to netdev->dev_addr go via helpers.
A lot of places pass netdev->dev_addr to of_get_ethdev_address() and
device_get_ethdev_addr() so this set adds new functions which wrap
the functionality.

v2 performs suggested code moves, adds a couple additional clean ups
on the device property side, and an extra patch converting drivers
which can benefit from device_get_ethdev_address().

v3 removes OF_NET and corrects kdoc.

      ethernet: make more use of device_get_ethdev_address() · 894b0fb0
      Jakub Kicinski authored 
      

Convert a few drivers to device_get_ethdev_address(),
saving a few LoC.

The check if addr is valid in netsec is superfluous,
device_get_ethdev_addr() already checks that (in
fwnode_get_mac_addr()).
