e859a60add net: phylink: avoid oops during initialisation
If we intend to use PCS operations, mac_pcs_get_state() will not be
implemented, so will be NULL. If we also intend to register the PCS
operations in mac_prepare() or mac_config(), then this leads to an
attempt to call NULL function pointer during phylink_start(). Avoid
this, but we must report the link is down.

1a545ebe38 drivers/net/wan/hdlc_cisco: Add hard_header_len
This driver didn't set hard_header_len. This patch sets hard_header_len
for it according to its header_ops->create function.

This driver's header_ops->create function (cisco_hard_header) creates
a header of (struct hdlc_header), so hard_header_len should be set to
sizeof(struct hdlc_header).

35149b2c04 samples/bpf: Add new sample xsk_fwd.c
This sample code illustrates the packet forwarding between multiple
AF_XDP sockets in multi-threading environment. All the threads and
sockets are sharing a common buffer pool, with each socket having
its own private buffer cache. The sockets are created with the
xsk_socket__create_shared() function, which allows multiple AF_XDP
sockets to share the same UMEM object.

Example 1: Single thread handling two sockets. Packets received
from socket A (on top of interface IFA, queue QA) are forwarded
to socket B (on top of interface IFB, queue QB) and vice-versa.
The thread is affinitized to CPU core C:

./xsk_fwd -i IFA -q QA -i IFB -q QB -c C

Example 2: Two threads, each handling two sockets. Packets from
socket A are sent to socket B (by thread X), packets
from socket B are sent to socket A (by thread X); packets from
socket C are sent to socket D (by thread Y), packets from socket
D are sent to socket C (by thread Y). The two threads are bound
to CPU cores CX and CY:

./xdp_fwd -i IFA -q QA -i IFB -q QB -i IFC -q QC -i IFD -q QD -c CX -c CY

2f6324a393 libbpf: Support shared umems between queues and devices
Add support for shared umems between hardware queues and devices to
the AF_XDP part of libbpf. This so that zero-copy can be achieved in
applications that want to send and receive packets between HW queues
on one device or between different devices/netdevs.

In order to create sockets that share a umem between hardware queues
and devices, a new function has been added called
xsk_socket__create_shared(). It takes the same arguments as
xsk_socket_create() plus references to a fill ring and a completion
ring. So for every socket that share a umem, you need to have one more
set of fill and completion rings. This in order to maintain the
single-producer single-consumer semantics of the rings.

You can create all the sockets via the new xsk_socket__create_shared()
call, or create the first one with xsk_socket__create() and the rest
with xsk_socket__create_shared(). Both methods work.

a1132430c2 xsk: Add shared umem support between devices
Add support to share a umem between different devices. This mode
can be invoked with the XDP_SHARED_UMEM bind flag. Previously,
sharing was only supported within the same device. Note that when
sharing a umem between devices, just as in the case of sharing a
umem between queue ids, you need to create a fill ring and a
completion ring and tie them to the socket (with two setsockopts,
one for each ring) before you do the bind with the
XDP_SHARED_UMEM flag. This so that the single-producer
single-consumer semantics of the rings can be upheld.

9647c57b11 xsk: i40e: ice: ixgbe: mlx5: Test for dma_need_sync earlier for better performance
Test for dma_need_sync earlier to increase
performance. xsk_buff_dma_sync_for_cpu() takes an xdp_buff as
parameter and from that the xsk_buff_pool reference is dug out. Perf
shows that this dereference causes a lot of cache misses. But as the
buffer pool is now sent down to the driver at zero-copy initialization
time, we might as well use this pointer directly, instead of going via
the xsk_buff and we can do so already in xsk_buff_dma_sync_for_cpu()
instead of in xp_dma_sync_for_cpu. This gets rid of these cache
misses.

Throughput increases with 3% for the xdpsock l2fwd sample application
on my machine.

that they have the same naming convention as the internal

this commit, only an umem reference has been added to the buffer pool
struct. But later commits will add other entities to it. These are
going to be entities that are different between different queue ids

c30a3c957c netlink: policy: correct validation type check
In the policy export for binary attributes I erroneously used
a != NLA_VALIDATE_NONE comparison instead of checking for the
two possible values, which meant that if a validation function
pointer ended up aliasing the min/max as negatives, we'd hit

Fix this to correctly check for only the two types that should
be handled here, i.e. range with or without warn-too-long.

   Update nfnetlink_unicast() to translate EAGAIN to ENOBUFS.

3) Remove repeated words in code comments, from Randy Dunlap.

4) Several patches for the flowtable selftests, from Fabian Frederick.

d2598bb809 RDMA/qib: Remove superfluous fallthrough statements
Commit 36a8f01cd2 ("IB/qib: Add congestion control agent
implementation") erroneously marked a couple of switch cases as /*
FALLTHROUGH */, which were later converted to fallthrough statements by
commit df561f6688 ("treewide: Use fallthrough pseudo-keyword"). This
triggered a Coverity warning about unreachable code.

Remove the fallthrough statements.

5fcface659 gpio: sprd: Clear interrupt when setting the type as edge
The raw interrupt status of GPIO maybe set before the interrupt is enabled,
which would trigger the interrupt event once enabled it from user side.
This is the case for edge interrupts only. Adding a clear operation when
setting interrupt type can avoid that.

There're a few considerations for the solution:
1) This issue is for edge interrupt only; The interrupts requested by users
   are IRQ_TYPE_LEVEL_HIGH as default, so clearing interrupt when request
   is useless.
2) The interrupt type can be set to edge when request and following up
   with clearing it though, but the problem is still there once users set
   the interrupt type to level trggier.
3) We can add a clear operation after each time of setting interrupt
   enable bit, but it is redundant for level trigger interrupt.

Therefore, the solution is this patch seems the best for now.
