Merge tag 'net-5.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
"Including fixes from can, xfrm, wifi, bluetooth, and netfilter.

Lots of various size fixes, the length of the tag speaks for itself.
Most of the 5.17-relevant stuff comes from xfrm, wifi and bt trees
which had been lagging as you pointed out previously. But there's also
a larger than we'd like portion of fixes for bugs from previous
releases.

Three more fixes still under discussion, including and xfrm revert for
uAPI error.

Current release - regressions:

- iwlwifi: don't advertise TWT support, prevent FW crash

- xfrm: fix the if_id check in changelink

- xen/netfront: destroy queues before real_num_tx_queues is zeroed

- bluetooth: fix not checking MGMT cmd pending queue, make scanning
work again

Current release - new code bugs:

- mptcp: make SIOCOUTQ accurate for fallback socket

- bluetooth: access skb->len after null check

- bluetooth: hci_sync: fix not using conn_timeout

- smc: fix cleanup when register ULP fails

- dsa: restore error path of dsa_tree_change_tag_proto

- iwlwifi: fix build error for IWLMEI

- iwlwifi: mvm: propagate error from request_ownership to the user

Previous releases - regressions:

- xfrm: fix pMTU regression when reported pMTU is too small

- xfrm: fix TCP MSS calculation when pMTU is close to 1280

- bluetooth: fix bt_skb_sendmmsg not allocating partial chunks

- ipv6: ensure we call ipv6_mc_down() at most once, prevent leaks

- ipv6: prevent leaks in igmp6 when input queues get full

- fix up skbs delta_truesize in UDP GRO frag_list

- eth: e1000e: fix possible HW unit hang after an s0ix exit

- eth: e1000e: correct NVM checksum verification flow

- ptp: ocp: fix large time adjustments

Previous releases - always broken:

- tcp: make tcp_read_sock() more robust in presence of urgent data

- xfrm: distinguishing SAs and SPs by if_id in xfrm_migrate

- xfrm: fix xfrm_migrate issues when address family changes

- dcb: flush lingering app table entries for unregistered devices

- smc: fix unexpected SMC_CLC_DECL_ERR_REGRMB error

- mac80211: fix EAPoL rekey fail in 802.3 rx path

- mac80211: fix forwarded mesh frames AC & queue selection

- netfilter: nf_queue: fix socket access races and bugs

- batman-adv: fix ToCToU iflink problems and check the result belongs
to the expected net namespace

- can: gs_usb, etas_es58x: fix opened_channel_cnt's accounting

- can: rcar_canfd: register the CAN device when fully ready

- eth: igb, igc: phy: drop premature return leaking HW semaphore

- eth: ixgbe: xsk: change !netif_carrier_ok() handling in
ixgbe_xmit_zc(), prevent live lock when link goes down

- eth: stmmac: only enable DMA interrupts when ready

- eth: sparx5: move vlan checks before any changes are made

- eth: iavf: fix races around init, removal, resets and vlan ops

- ibmvnic: more reset flow fixes

Misc:

- eth: fix return value of __setup handlers"

ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()

While investigating on why a synchronize_net() has been added recently
in ipv6_mc_down(), I found that igmp6_event_query() and igmp6_event_report()
might drop skbs in some cases.

Discussion about removing synchronize_net() from ipv6_mc_down()
will happen in a different thread.

ipv6: mcast: use rcu-safe version of ipv6_get_lladdr()

ipv6: mcast: use rcu-safe version of ipv6_get_lladdr()

Some time ago 8965779d2c0e ("ipv6,mcast: always hold idev->lock before mca_lock")
switched ipv6_get_lladdr() to __ipv6_get_lladdr(), which is rcu-unsafe
version. That was OK, because idev->lock was held for these codepaths.

In 88e2ca308094 ("mld: convert ifmcaddr6 to RCU") these external locks were
removed, so we probably need to restore the original rcu-safe call.

Otherwise, we occasionally get a machine crashed/stalled with the following
