6b398f1c28 wifi: mac80211: cleanup auth_data only if association continues
If the association command fails then the authentication is still valid
and it makes sense to keep it alive. Otherwise, we would currently get
into an inconsistent state because mac80211 on the one hand is
disconnected but on the other hand the state is not entirely cleared
and a new authentication could not continue.

63ef576c9f wifi: iwlwifi: mvm: use correct sta ID for IGTK/BIGTK
We don't (yet) send the IGTK down to the firmware, but when
we do it needs to be with the broadcast station ID, not the
multicast station ID. Same for the BIGTK, which we may send
already if firmware advertises it (but it doesn't yet.)

f05d1e04c4 wifi: iwlwifi: mvm: offload IGTK in AP if BIGTK is supported
We can't really know easily if a BIGTK will be used, but
in case firmware supports BIGTK it also supports the very
easy IGTK use (nothing to do on the host), and requires
that we program both IGTK and BIGTK to be able to use the
BIGTK. Thus, change the condition here to set the keys in
firmware (both IGTK/BIGTK) if BIGTK is supported.

7186d271ac wifi: iwlwifi: fix opmode start/stop race
There's a race when the device is unbound (maybe because the
module is unloaded) while the opmode start hasn't finished yet.
The complete(request_firmware_complete) after the opmode start
was meant (and commented accordingly) to prevent this problem,
but it's not sufficient when the opmode module is loaded after
the firmware load already completed, which happens regularly
now because firmware load doesn't require userspace, unlike
module load.

Fix this by using the existing opmode registration mutex to
protected the start/stop flows against each other properly.

90d862f370 powerpc/bpf: use bpf_jit_binary_pack_[alloc|finalize|free]
Use bpf_jit_binary_pack_alloc in powerpc jit. The jit engine first
writes the program to the rw buffer. When the jit is done, the program
is copied to the final location with bpf_jit_binary_pack_finalize.
With multiple jit_subprogs, bpf_jit_free is called on some subprograms
that haven't got bpf_jit_binary_pack_finalize() yet. Implement custom
bpf_jit_free() like in commit 1d5f82d9dd ("bpf, x86: fix freeing of
not-finalized bpf_prog_pack") to call bpf_jit_binary_pack_finalize(),
if necessary. As bpf_flush_icache() is not needed anymore, remove it.

465cabc97b powerpc/code-patching: introduce patch_instructions()
patch_instruction() entails setting up pte, patching the instruction,
clearing the pte and flushing the tlb. If multiple instructions need
to be patched, every instruction would have to go through the above
drill unnecessarily. Instead, introduce patch_instructions() function
that sets up the pte, clears the pte and flushes the tlb only once
per page range of instructions to be patched. Duplicate most of the
patch_instruction() code instead of merging with it, to avoid the
performance degradation observed on ppc32, for patch_instruction(),
with the code path merged. Also, setup poking_init() always as BPF
expects poking_init() to be setup even when STRICT_KERNEL_RWX is off.

aad26d3b6a powerpc/32s: Implement local_flush_tlb_page_psize()
There's a single call to local_flush_tlb_page_psize() in the code
patching code. That call is never executed on 32-bit Book3S,
because it's guarded by mm_patch_enabled() which is essentially a
radix_enabled() check, which is always false on 32s.

However depending on how the optimiser sees things it may still trip
over the BUILD_BUG() in the 32s stub of local_flush_tlb_page_psize().

To avoid that, implement it in terms of flush_range() so that if it ever
becomes called it should function, even if not optimally.

Note that flush_range() deals with page aligning the address and so on,
and that 32s doesn't support huge pages so there should be no issue with
non-standard page sizes needing to be flushed.

bdf24b4bdf Merge branch 'tcp-ts-usec-resolution'
Eric Dumazet says:

====================
tcp: add optional usec resolution to TCP TS

As discussed in various public places in 2016, Google adopted
usec resolution in RFC 7323 TS values, at Van Jacobson suggestion.

Goals were :

1) better observability of delays in networking stacks/fabrics.

2) better disambiguation of events based on TSval/ecr values.

3) building block for congestion control modules needing usec resolution.

Back then we implemented a schem based on private SYN options
to safely negotiate the feature.

For upstream submission, we chose to use a much simpler route
attribute because this feature is probably going to be used
in private networks.

This has been implemented in our private kernels.

Goals were :

1) better observability of delays in networking stacks.
2) better disambiguation of events based on TSval/ecr values.
3) building block for congestion control modules needing usec resolution.

Back then we implemented a schem based on private SYN options
to negotiate the feature.

For upstream submission, we chose to use a route attribute,
because this feature is probably going to be used in private
networks [1] [2].

ip route add 10/8 ... features tcp_usec_ts

Note that RFC 7323 recommends a
  "timestamp clock frequency in the range 1 ms to 1 sec per tick.",
but also mentions
  "the maximum acceptable clock frequency is one tick every 59 ns."

[1] Unfortunately RFC 7323 5.5 (Outdated Timestamps) suggests
to invalidate TS.Recent values after a flow was idle for more
than 24 days. This is the part making usec_ts a problem
for peers following this recommendation for long living
idle flows.

[2] Attempts to standardize usec ts went nowhere:

73ed8e0338 tcp: fix cookie_init_timestamp() overflows
cookie_init_timestamp() is supposed to return a 64bit timestamp
suitable for both TSval determination and setting of skb->tstamp.

Unfortunately it uses 32bit fields and overflows after
2^32 * 10^6 nsec (~49 days) of uptime.

Generated TSval are still correct, but skb->tstamp might be set
far away in the past, potentially confusing other layers.

tcp_ns_to_ts() is changed to return a full 64bit value,
ts and ts_now variables are changed to u64 type,
and TSMASK is removed in favor of shifts operations.

While we are at it, change this sequence:
		ts >>= TSBITS;
		ts--;
		ts <<= TSBITS;
		ts |= options;
to:
		ts -= (1UL << TSBITS);

2bdcdad693 dt-bindings: pinctrl: nuvoton,npcm845: Add missing additionalProperties on gpio child nodes
Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present for any node. Add the missing addtionalProperties to the 'gpio'
child nodes.

caf963efd4 dt-bindings: pinctrl: brcm: Ensure all child node properties are documented
The Broadcom pinctrl bindings are incomplete for child nodes as they are
missing 'unevaluatedProperties: false' to prevent unknown properties.
Fixing this reveals many warnings including having grandchild nodes in some
cases. Many cases in the examples use 'group' property which is
undocumented and not used by the driver. As the schemas define 'pins', I
assume that is the correct name except for the one case, 6358, using
'groups' which is documented.

Beniamino Galvani says:

====================
net: consolidate IPv6 route lookup for UDP tunnels

At the moment different UDP tunnels rely on different functions for
IPv6 route lookup, and those functions all implement the same
logic.

Extend the generic lookup function so that it is suitable for all UDP
tunnel implementations, and then adapt bareudp, geneve and vxlan to
use it.

This is similar to what already done for IPv4.

2aceb896ee vxlan: use generic function for tunnel IPv6 route lookup
The route lookup can be done now via generic function
udp_tunnel6_dst_lookup() to replace the custom implementation in
vxlan6_get_route().

946fcfdbc5 ipv6: add new arguments to udp_tunnel6_dst_lookup()
We want to make the function more generic so that it can be used by
other UDP tunnel implementations such as geneve and vxlan. To do that,
add the following arguments:

 - source and destination UDP port;
 - ifindex of the output interface, needed by vxlan;
 - the tos, because in some cases it is not taken from struct
   ip_tunnel_info (for example, when it's inherited from the inner
   packet);
 - the dst cache, because not all tunnel types (e.g. vxlan) want to
   use the one from struct ip_tunnel_info.

With these parameters, the function no longer needs the full struct
ip_tunnel_info as argument and we can pass only the relevant part of
it (struct ip_tunnel_key).

This is similar to what already done for IPv4 in commit 72fc68c635
("ipv4: add new arguments to udp_tunnel_dst_lookup()").

fc47e86dbf ipv6: rename and move ip6_dst_lookup_tunnel()
At the moment ip6_dst_lookup_tunnel() is used only by bareudp.
Ideally, other UDP tunnel implementations should use it, but to do so
the function needs to accept new parameters that are specific for UDP
tunnels, such as the ports.

Prepare for these changes by renaming the function to
udp_tunnel6_dst_lookup() and move it to file
net/ipv6/ip6_udp_tunnel.c.

This is similar to what already done for IPv4 in commit bf3fcbf7e7
("ipv4: rename and move ip_route_output_tunnel()").
