====================
netlink: nested policy validation
This adds nested policy validation, which lets you specify the
nested attribute type, e.g. NLA_NESTED with sub-policy, or the
new NLA_NESTED_ARRAY with sub-sub-policy.
Changes in v2:
* move setting the bad attr pointer/message into validate_nla()
* remove the recursion patch since that's no longer needed
* simply skip the generic bad attr pointer/message setting in
case of nested nla_validate() failing since that could fail
only due to validate_nla() failing inside, which already sets
the extack information
Changes in v3:
* fix NLA_REJECT to have an error message if none is in policy
====================

Sometimes nested netlink attributes are just used as arrays, with
the nla_type() of each not being used; we have this in nl80211 and
e.g. NFTA_SET_ELEM_LIST_ELEMENTS.
Add the ability to validate this type of message directly in the
policy, by adding the type NLA_NESTED_ARRAY which does exactly
this: require a first level of nesting but ignore the attribute
type, and then inside each require a second level of nested and
validate those attributes against a given policy (if present).
Note that some nested array types actually require that all of
the entries have the same index, this is possible to express in
a nested policy already, apart from the validation that only the
one allowed type is used.

Now that we have a validation_data pointer, and the len field in
the policy is unused for NLA_NESTED, we can allow using them both
to have nested validation. This can be nice in code, although we
still have to use nla_parse_nested() or similar which would also
take a policy; however, it also serves as documentation in the
policy without requiring a look at the code.

This unifies the code between nla_parse() which sets the bad
attribute pointer and an error message, and nla_validate()
which only sets the bad attribute pointer.
It also cleans up the code for NLA_REJECT and paves the way
for nested policy validation, as it will allow us to easily
skip setting the "generic" message without any extra args
like the **error_msg now, just passing the extack through is
now enough.
While at it, remove the unnecessary label in nla_parse().

The validation data is only used within the policy that
should usually already be const, and isn't changed in any
code that uses it. Therefore, make the validation_data
pointer const.
While at it, remove the duplicate variable in the bitfield
validation that I'd otherwise have to change to const.

hook_head = rcu_dereference(net->nf.hooks_arp[hook]);

xfrm_output_resume passes skb_dst(skb)->ops->family as its 'pf' arg so compiler

(NFPROTO_IPV4 or NFPROTO_IPV6 are only possible cases).
Avoid this by adding an explicit WARN_ON_ONCE() check.

The nft_set_gc_batch_check() checks whether gc buffer is full.
If gc buffer is full, gc buffer is released by
the nft_set_gc_batch_complete() internally.
In case of rbtree, the rb_erase() should be called before calling the
nft_set_gc_batch_complete(). therefore the rb_erase() should
be called before calling the nft_set_gc_batch_check() too.

deleted on device
We configured iptables as below, which only allowed incoming data on
established connections:
iptables -t mangle -A PREROUTING -m state --state ESTABLISHED -j ACCEPT
iptables -t mangle -P PREROUTING DROP
When deleting a secondary address, current masquerade implements would
flush all conntracks on this device. All the established connections on
primary address also be deleted, then subsequent incoming data on the
connections would be dropped wrongly because it was identified as NEW
connection.
So when an address was delete, it should only flush connections related
with the address.

Fix error distribution by immediately delivering the errors to all the
affected calls rather than deferring them to a worker thread. The problem
with the latter is that retries and things can happen in the meantime when we
want to stop that sooner.
To this end:
(1) Stop the error distributor from removing calls from the error_targets
list so that peer->lock isn't needed to synchronise against other adds
and removals.
(2) Require the peer's error_targets list to be accessed with RCU, thereby
avoiding the need to take peer->lock over distribution.
(3) Don't attempt to affect a call's state if it is already marked complete.

It seems that enabling IPV6_RECVERR on an IPv6 socket doesn't also turn on
IP_RECVERR, so neither local errors nor ICMP-transported remote errors from
IPv4 peer addresses are returned to the AF_RXRPC protocol.

AF_INET6 case to the AF_INET case to turn on all the AF_INET options too in

Make the following changes to improve the robustness of the code that sets
up a new service call:
(1) Cache the rxrpc_sock struct obtained in rxrpc_data_ready() to do a
service ID check and pass that along to rxrpc_new_incoming_call().
This means that I can remove the check from rxrpc_new_incoming_call()
without the need to worry about the socket attached to the local
endpoint getting replaced - which would invalidate the check.
(2) Cache the rxrpc_peer struct, thereby allowing the peer search to be
done once. The peer is passed to rxrpc_new_incoming_call(), thereby
saving the need to repeat the search.
This also reduces the possibility of rxrpc_publish_service_conn()
BUG()'ing due to the detection of a duplicate connection, despite the
initial search done by rxrpc_find_connection_rcu() having turned up
nothing.
This BUG() shouldn't ever get hit since rxrpc_data_ready() *should* be
non-reentrant and the result of the initial search should still hold
true, but it has proven possible to hit.
I *think* this may be due to __rxrpc_lookup_peer_rcu() cutting short
the iteration over the hash table if it finds a matching peer with a
zero usage count, but I don't know for sure since it's only ever been
hit once that I know of.
Another possibility is that a bug in rxrpc_data_ready() that checked
the wrong byte in the header for the RXRPC_CLIENT_INITIATED flag
might've let through a packet that caused a spurious and invalid call
to be set up. That is addressed in another patch.
(3) Fix __rxrpc_lookup_peer_rcu() to skip peer records that have a zero
usage count rather than stopping and returning not found, just in case
there's another peer record behind it in the bucket.
(4) Don't search the peer records in rxrpc_alloc_incoming_call(), but
rather either use the peer cached in (2) or, if one wasn't found,
preemptively install a new one.

In the input path, a received sk_buff can be marked for rejection by
setting RXRPC_SKB_MARK_* in skb->mark and, if needed, some auxiliary data
(such as an abort code) in skb->priority. The rejection is handled by
queueing the sk_buff up for dealing with in process context. The output
code reads the mark and priority and, theoretically, generates an
appropriate response packet.
However, if RXRPC_SKB_MARK_BUSY is set, this isn't noticed and an ABORT
message with a random abort code is generated (since skb->priority wasn't
set to anything).
Fix this by outputting the appropriate sort of packet.
Also, whilst we're at it, most of the marks are no longer used, so remove
them and rename the remaining two to something more obvious.

(2) If the sk_buff doesn't have a timestamp set when rxrpc_data_ready()
collects it, set it at that point.
(3) Allow ACKs to be requested on the last packet of a client call, but
not a service call. We need to be careful lest we undo:

rxrpc: Don't request an ACK on the last DATA packet of a call's Tx phase
but that only really applies to service calls that we're handling,
since the client side gets to send the final ACK (or not).
(4) When about to transmit an ACK or DATA packet, record the Tx timestamp
before only; don't update the timestamp afterwards.
(5) Switch the ordering between recording the serial and recording the
timestamp to always set the serial number first. The serial number
shouldn't be seen referenced by an ACK packet until we've transmitted
the packet bearing it - so in the Rx path, we don't need the timestamp
until we've checked the serial number.

There's a check in rxrpc_data_ready() that's checking the CLIENT_INITIATED
flag in the packet type field rather than in the packet flags field.
Fix this by creating a pair of helper functions to check whether the packet
is going to the client or to the server and use them generally.

As a temporary stage in the 22560 devices bring up, we disabled

Now we would like to use power save so enable the balanced mode,

In future devices we will have more than one debug buffer.
Prepare the infrastructure for allocation and release of

of structures and moving it to trans section, where they will
be visible to opmode and FW.

When operating as a soft ap with wep security, the key was not
configured to the fw for the stations, based on the fact that the
key will be specified in the tx command.
However, in the new tx api the tx command does not include the key,
which resulted in all data frames going out un-encrypted.
Fix it by configuring the key for all the stations as they are added.

Today, the length of a debug message in iwl_trans_pcie_reclaim
may pass the MAX_MSG_LEN, which is 110.
An example for this kind of message is:
'iwl_trans_pcie_reclaim: Read index for DMA queue txq id (2),
last_to_free 65535 is out of range [0-65536] 2 2.'
Cut the message a bit so it will fit the allowed MAX_MSG_LEN.

If the HW is not responding at probe time, fail immediately complaining
about it. Without this, we see that the kernel spends > 100ms trying to
load firmware (even gives an incorrect impression that it actually
loaded a firmware) and do unnecesary processing before concluding that
the device is not accessible:
