RxRPC: 2nd rewrite part 1

Okay, I'm in the process of rewriting the RxRPC rewrite.  The primary aim of
this second rewrite is to strictly control the number of active connections we
know about and to get rid of connections we don't need much more quickly.

On top of this, there are fixes to the protocol handling which will all occur
in later parts.

Here's the first set of patches from the second go, aimed at net-next.  These
are all fixes and cleanups preparatory to the main event.

Notable parts of this set include:

 (1) A fix for the AFS filesystem to wait for outstanding calls to complete
     before closing the RxRPC socket.

 (2) Differentiation of local and remote abort codes.  At a future point
     userspace will get to see this via control message data on recvmsg().

 (3) Absorb the rxkad module into the af_rxrpc module to prevent a dependency
     loop.

 (4) Create a null security module and unconditionalise calls into the
     security module that's in force (there will always be a security module
     applied to a connection, even if it's just the null one).
====================

Absorb the rxkad security module into the af_rxrpc module so that there's
only one module file.  This avoids a circular dependency whereby rxkad pins
af_rxrpc and cached connections pin rxkad but can't be manually evicted
(they will expire eventually and cease pinning).

With this change, af_rxrpc can just be unloaded, despite having cached
connections.

In the rxrpc_connection and rxrpc_call structs, there's one field to hold
the abort code, no matter whether that value was generated locally to be
sent or was received from the peer via an abort packet.

Split the abort code fields in two for cleanliness sake and add an error
field to hold the Linux error number to the rxrpc_call struct too
(sometimes this is generated in a context where we can't return it to
userspace directly).

Furthermore, add a skb mark to indicate a packet that caused a local abort
to be generated so that recvmsg() can pick up the correct abort code.  A
future addition will need to be to indicate to userspace the difference
between aborts via a control message.

The afs filesystem needs to wait for any outstanding asynchronous calls
(such as FS.GiveUpCallBacks cleaning up the callbacks lodged with a server)
to complete before closing the AF_RXRPC socket when unloading the module.

This may occur if the module is removed too quickly after unmounting all
filesystems.  This will produce an error report that looks like:

net: fix udp pull header breakage

Commit e6afc8ac ("udp: remove headers from UDP packets before
queueing") modified udp receive processing to pull headers before
enqueue and to not expect them on dequeue.

The patch missed protocols on top of udp with in-kernel
implementations that have their own skb_recv_datagram calls and
dequeue logic. Modify these datapaths to also no longer expect
a udp header at skb->data.

Sunrpc and rxrpc are the only two protocols that call this
function and contain references to udphr (some others, like tipc,
are based on encap_rcv, which acts before enqueue, before the
the header pull).

Multipath route lookups should consider knowledge about next hops and not

                                  3|
                                   |
                                  [h1]  12.0.0.1

host h1 with IP 12.0.0.1 has 2 paths to host h3 at 15.0.0.5:

    root@h1:~# ip ro ls
    ...
    12.0.0.0/24 dev swp1  proto kernel  scope link  src 12.0.0.1
    15.0.0.0/16
            nexthop via 12.0.0.2  dev swp1 weight 1
            nexthop via 12.0.0.3  dev swp1 weight 1
    ...

If the link between tor3 and tor1 is down and the link between tor1
and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups
in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and
ssh 15.0.0.5 gets the other. Connections that attempt to use the
12.0.0.2 nexthop fail since that neighbor is not reachable:

    root@h1:~# ip neigh show
    ...
    12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE
    12.0.0.2 dev swp1  FAILED
    ...

The failed path can be avoided by considering known neighbor information
when selecting next hops. If the neighbor lookup fails we have no
knowledge about the nexthop, so give it a shot. If there is an entry
then only select the nexthop if the state is sane. This is similar to
what fib_detect_death does.

To maintain backward compatibility use of the neighbor information is
based on a new sysctl, fib_multipath_use_neigh.

ALE APIs expect to receive port masks as input values for arguments
port_mask, untag, reg_mcast, unreg_mcast. But there are few places in
code where port masks are passed left-shifted by cpsw_priv->host_port,
like below:

 cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan,
		  ALE_ALL_PORTS << priv->host_port,
		  ALE_ALL_PORTS << priv->host_port, 0, 0);

and cpsw is still working just because priv->host_port == 0
and has never ever been changed.

Hence, fix port_mask parameters in ALE APIs calls and drop
"<< priv->host_port" from all places where it's used to
shift valid port mask.

        int imm;
        struct bpf_map *map_ptr;

and later on in states_equal() does memcmp(&old->regs[i], &cur->regs[i],..)
to find equivalent states.
Throughout the code of verifier there are assignements to 'imm' and 'map_ptr'
fields and it's not obvious that most of the assignments into 'imm' don't
need to clear extra 4 bytes (like mark_reg_unknown_value() does) to make sure
that memcmp doesn't go over junk left from 'map_ptr' assignment.

   - Runtime PM documentation update to make it describe what needs to
     be done during device removal more precisely (Krzysztof Kozlowski).

   - Stale comment removal cleanup in the cpufreq-dt driver (Viresh
