2022-07-15wifi: mac80211: RCU-ify link/link_conf pointersJohannes Berg
Since links can be added and removed dynamically, we need to somehow protect the sdata->link[] and vif->link_conf[] array pointers from disappearing when accessing them without locks. RCU-ify the pointers to achieve this, which requires quite a bit of rework. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2022-07-15wifi: mac80211_hwsim: use 32-bit skb cookieJohannes Berg
We won't really have enough skbs to need a 64-bit cookie, and on 32-bit platforms storing the 64-bit cookie into the void *rate_driver_data doesn't work anyway. Switch back to using just a 32-bit cookie and uintptr_t for the type to avoid compiler warnings about all this.

2022-07-15crypto: sa2ul - Check engine status before enablingAndrew Davis
There is a engine status register that can be used to check if the different HW crypto engines are enabled. Check that first and then only try to enable the engines if they are not already on. This has a couple benefits. First we don't need to use match_data for this. Second, this driver can now work on HS devices where the engine control registers are read-only and writing causes a firewall exception.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net Pull networking fixes from Jakub Kicinski: "Including fixes from netfilter, bpf and wireless. Still no major regressions, the release continues to be calm. An uptick of fixes this time around due to trivial data race fixes and patches flowing down from subtrees. There has been a few driver fixes (particularly a few fixes for false positives due to 66e4c8d95008 which went into -next in May!) that make me worry the wide testing is not exactly fully through. So "calm" but not "let's just cut the final ASAP" vibes over here.
