In some graceful updates that get initially triggered by the
RESET event, especially with older firmware, the fw_generation
bits don't change but the fw_status is seen to go to 0 then back
to 1.  However, the driver didn't perform the restart, remained
waiting for fw_generation to change, and got left in limbo.

This is because the clearing of idev->fw_status_ready to 0
didn't happen correctly as it was buried in the transition
trigger: since the transition down was triggered not here
but in the RESET event handler, the clear to 0 didn't happen,
so the transition back to 1 wasn't detected.

Fix this particular case by bringing the setting of
idev->fw_status_ready back out to where it was before.

IPv6 has this hack changing sk->sk_prot when an IPv6 socket
is 'converted' to an IPv4 one with IPV6_ADDRFORM option.

This operation is only performed for TCP and UDP, knowing
their 'struct proto' for the two network families are populated
in the same way, and can not disappear while a reader
might use and dereference sk->sk_prot.

If we think about it all reads of sk->sk_prot while
either socket lock or RTNL is not acquired should be using READ_ONCE().

Also note that other layers like MPTCP, XFRM, CHELSIO_TLS also
write over sk->sk_prot.

With the increase number of tests, one CI instance, using a debug kernel
config and not recent hardware, takes around 10 minutes to execute the
slowest MPTCP test: mptcp_join.sh.

Even if most CIs don't take that long to execute these tests --
typically max 10 minutes to run all selftests -- it will help some of
them if the timeout is increased.

The timeout could be disabled but it is always good to have an extra
safeguard, just in case.

Please note that on slow public CIs with kernel debug settings, it has
been observed it can easily take up to 45 minutes to execute all tests
in this very slow environment with other jobs running in parallel.
The slowest test, mptcp_join.sh takes ~30 minutes in this case.

In such environments, the selftests timeout set in the 'settings' file
is disabled because this environment is known as being exceptionnally
slow. It has been decided not to take such exceptional environments into
account and set the timeout to 20min.

bpf_prog_pack_free() uses header->size to decide whether the header
should be freed with module_memfree() or the bpf_prog_pack logic.
However, in kvmalloc() failure path of bpf_jit_binary_pack_alloc(),
header->size is not set yet. As a result, bpf_prog_pack_free() may treat
a slice of a pack as a standalone kvmalloc'd header and call
module_memfree() on the whole pack. This in turn causes use-after-free by
other users of the pack.

Fix this by setting ro_header->size before freeing ro_header.

net: marvell: prestera: add basic routes offloading

Add support for blackhole and local routes for Marvell Prestera driver.
Subscribe on fib notifications and handle add/del.

Add features:
 - Support route adding.
   e.g.: "ip route add blackhole 7.7.1.1/24"
   e.g.: "ip route add local 9.9.9.9 dev sw1p30"
 - Support "rt_trap", "rt_offload", "rt_offload_failed" flags
 - Handle case, when route in "local" table overlaps route in "main" table
   example:
        ip ro add blackhole 7.7.7.7
        ip ro add local 7.7.7.7 dev sw1p30
        # blackhole route will be deoffloaded. rt_offload flag disappeared

Limitations:
 - Only "blackhole" and "local" routes supported. "nexthop" routes is TRAP
   for now and will be implemented soon.
 - Only "local" and "main" tables supported

Pull networking fixes from Jakub Kicinski:
 "Including fixes from wireless and netfilter.

  Current release - regressions:

   - dsa: lantiq_gswip: fix use after free in gswip_remove()

   - smc: avoid overwriting the copies of clcsock callback functions

  Current release - new code bugs:

   - iwlwifi:
      - fix use-after-free when no FW is present
      - mei: fix the pskb_may_pull check in ipv4
      - mei: retry mapping the shared area
      - mvm: don't feed the hardware RFKILL into iwlmei

  Previous releases - regressions:

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

   - tipc: fix wrong publisher node address in link publications

   - iwlwifi: mvm: don't send SAR GEO command for 3160 devices, avoid FW
     assertion

   - bgmac: make idm and nicpm resource optional again

   - atl1c: fix tx timeout after link flap

  Previous releases - always broken:

   - vsock: remove vsock from connected table when connect is
     interrupted by a signal

   - ping: change destination interface checks to match raw sockets

   - crypto: af_alg - get rid of alg_memory_allocated to avoid confusing
     semantics (and null-deref) after SO_RESERVE_MEM was added

   - ipv6: make exclusive flowlabel checks per-netns

   - bonding: force carrier update when releasing slave

   - sched: limit TC_ACT_REPEAT loops

   - bridge: multicast: notify switchdev driver whenever MC processing
     gets disabled because of max entries reached

   - wifi: brcmfmac: fix crash in brcm_alt_fw_path when WLAN not found

   - iwlwifi: fix locking when "HW not ready"

   - phy: mediatek: remove PHY mode check on MT7531

   - dsa: mv88e6xxx: flush switchdev FDB workqueue before removing VLAN

   - dsa: lan9303:
      - fix polarity of reset during probe
      - fix accelerated VLAN handling"
