Recent bpf-next merge brought in header changes which uncovered
includes missing in net-next which were not present in bpf-next.
Build problems happen only on less-popular arches like hppa,
sparc, alpha etc.
I could repro the build problem with ice but not the mlx5 problem
Abdul was reporting. mlx5 does look like it should include filter.h,
anyway.

This patch adds support for scatter gather DMA. DMA in PMAC splits
the packet into several buffers when the MTU on the CPU port is
less than the MTU of the switch. The first buffer starts at an
offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
offset. Thanks to this patch, the user can still connect to the
device in such a situation. For normal configurations, the patch
has no effect on performance.

Add support for external timestamp and periodic signal output.
TJA1103 have one periodic signal and one external time stamp signal that
can be multiplexed on all 11 gpio pins.
The periodic signal can be only enabled or disabled. Have no start time
and if is enabled will be generated with a period of one second in sync
with the LTC seconds counter. The phase change is possible only with a
half of a second.
The external timestamp signal has no interrupt and no valid bit and
that's why the timestamps are handled by polling in .do_aux_work.

====================
net/sched: Pass originating device to drivers offloading ct connection
Currently, drivers register to a ct zone that can be shared by multiple
devices. This can be inefficient for the driver to offload, as it
needs to handle all the cases where the tuple can come from,
instead of where it's most likely will arive from.
For example, consider the following tc rules:
tc filter add dev dev1 ... flower action ct commit zone 5 \
action mirred egress redirect dev dev2
tc filter add dev dev2 ... flower action ct zone 5 \
action goto chain chain 2
tc filter add dev dev2 ... flower ct_state +trk+est ... \
action mirred egress redirect dev dev1
Both dev2 and dev1 register to the zone 5 flow table (created
by act_ct). A tuple originating on dev1, going to dev2, will
be offloaded to both devices, and both will need to offload
both directions, resulting in 4 total rules. The traffic
will only hit originiating tuple on dev1, and reply tuple
on dev2.
By passing the originating device that created the connection
with the tuple, dev1 can choose to offload only the originating
tuple, and dev2 only the reply tuple. Resulting in a more
efficient offload.
The first patch adds an act_ct nf conntrack extension, to
temporarily store the originiating device from the skb before
offloading the connection once the connection is established.
Once sent to offload, it fills the tuple originating device.
The second patch get this information from tuples
which pass in openvswitch.
The third patch is Mellanox driver ct offload implementation using
this information to provide a hint to firmware of where this
offloaded tuple packets will arrive from (LOCAL or UPLINK port),
and thus increase insertion rate.

Get originating device from tuple offload metadata match ingress_ifindex,
and set flow_source hint to either LOCAL for vf/sf reps, UPLINK for
uplink/wire/tunnel devices/bond, or ANY (as before this patch)
for all others.
This allows lower layer (software steering or firmware) to insert the tuple
rule only in one table (either rx or tx) instead of two (rx and tx).

Driver offloading ct tuples can use the information of which devices
received the packets that created the offloaded connections, to
more efficiently offload them only to the relevant device.
Add new act_ct nf conntrack extension, which is used to store the skb
devices before offloading the connection, and then fill in the tuple

Use dma_set_mask_and_coherent() instead of unrolling it with some
dma_set_mask()+dma_set_coherent_mask().
Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never
fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
That said, 'high_dma' can only be 1 after a successful
dma_set_mask_and_coherent().

v3:
- Report 'backlog' (bytes) instead of 'qlen' (number of packets)
v2:
- Fix sparse warning (use rcu_dereference)
This patch adds support for the queue depth in IOAM trace data fields.
The draft [1] says the following:
The "queue depth" field is a 4-octet unsigned integer field. This
field indicates the current length of the egress interface queue of
the interface from where the packet is forwarded out. The queue
depth is expressed as the current amount of memory buffers used by
the queue (a packet could consume one or more memory buffers,
depending on its size).
An existing function (i.e., qdisc_qstats_qlen_backlog) is used to
retrieve the current queue length without reinventing the wheel.
Note: it was tested and qlen is increasing when an artificial delay is
added on the egress with tc.

This implements TCP ULP for SMC, helps applications to replace TCP with
SMC protocol in place. And we use it to implement transparent
replacement.
This replaces original TCP sockets with SMC, reuse TCP as clcsock when
calling setsockopt with TCP_ULP option, and without any overhead.
To replace TCP sockets with SMC, there are two approaches:
- use setsockopt() syscall with TCP_ULP option, if error, it would
fallback to TCP.
- use BPF prog with types BPF_CGROUP_INET_SOCK_CREATE or others to
replace transparently. BPF hooks some points in create socket, bind
and others, users can inject their BPF logics without modifying their
applications, and choose which connections should be replaced with SMC
by calling setsockopt() in BPF prog, based on rules, such as TCP tuples,
PID, cgroup, etc...
BPF doesn't support calling setsockopt with TCP_ULP now, I will send the
patches after this accepted.

====================
RDMA device net namespace support for SMC
This patch set introduces net namespace support for linkgroups.
Path 1 is the main approach to implement net ns support.
Path 2 - 4 are the additional modifications to let us know the netns.
Also, I will submit changes of smc-tools to github later.
Currently, smc doesn't support net namespace isolation. The ibdevs
registered to smc are shared for all linkgroups and connections. When
running applications in different net namespaces, such as container
environment, applications should only use the ibdevs that belongs to the
same net namespace.
This adds a new field, net, in smc linkgroup struct. During first
contact, it checks and find the linkgroup has same net namespace, if
not, it is going to create and initialized the net field with first
link's ibdev net namespace. When finding the rdma devices, it also checks
the sk net device's and ibdev's net namespaces. After net namespace
destroyed, the net device and ibdev move to root net namespace,
linkgroups won't be matched, and wait for lgr free.
If rdma net namespace exclusive mode is not enabled, it behaves as
before.
Steps to enable and test net namespaces:
1. enable RDMA device net namespace exclusive support
rdma system set netns exclusive # default is shared
2. create new net namespace, move and initialize them
ip netns add test1
rdma dev set mlx5_1 netns test1
ip link set dev eth2 netns test1
ip netns exec test1 ip link set eth2 up
ip netns exec test1 ip addr add ${HOST_IP}/26 dev eth2
3. setup server and client, connect N <-> M
ip netns exec test1 smc_run sockperf server --tcp # server
ip netns exec test1 smc_run sockperf pp --tcp -i ${SERVER_IP} # client
4. netns isolated linkgroups (2 * 2 mesh) with their own linkgroups

Currently, rdma device supports exclusive net namespace isolation,
however linkgroup doesn't know and support ibdev net namespace.
Applications in the containers don't want to share the nics if we
enabled rdma exclusive mode. Every net namespaces should have their own
linkgroups.
This patch introduce a new field net for linkgroup, which is standing
for the ibdev net namespace in the linkgroup. The net in linkgroup is
initialized with the net namespace of link's ibdev. It compares the net
of linkgroup and sock or ibdev before choose it, if no matched, create
new one in current net namespace. If rdma net namespace exclusive mode
is not enabled, it behaves as before.

1) Expose debugfs for dumping the SW steering resources
2) Removing unused fields
3) support for matching on new fields
4) steering optimization for RX/TX-only rules
5) Make Software steering the default steering mechanism when
available, applies only to Switchdev mode FDB
From Yevgeny Kliteynik and Muhammad Sammar:
- Patch 1 fixes an error flow in creating matchers
- Patch 2 fix lower case macro prefix "mlx5_" to "MLX5_"
- Patch 3 removes unused struct member in mlx5dr_matcher
- Patch 4 renames list field in matcher struct to list_node to reflect the
fact that is field is for list node that is stored on another struct's lists
- Patch 5 adds checking for valid Flex parser ID value
- Patch 6 adds the missing reserved fields to dr_match_param and aligns it to
the format that is defined by HW spec
- Patch 7 adds support for dumping SW steering (SMFS) resources using debugfs
in CSV format: domain and its tables, matchers and rules
- Patch 8 adds support for a new destination type - UPLINK
- Patch 9 adds WARN_ON_ONCE on refcount checks in SW steering object destructors
- Patches 10, 11, 12 add misc5 flow table match parameters and add support for
matching on tunnel headers 0 and 1
- Patch 13 adds support for matching on geneve_tlv_option_0_exist field
- Patch 14 implements performance optimization for for empty or RX/TX-only
matchers by splitting RX and TX matchers handling: matcher connection in the
matchers chain is split into two separate lists (RX only and TX only), which
solves a usecase of many RX or TX only rules that create a long chain of
RX/TX-only paths w/o the actual rules
- Patch 15 ignores modify TTL if device doesn't support it instead of
adding and unsupported action
- Patch 16 sets SMFS as a default steering mode

This patch uses common cmdq resource allocate/free/query APIs to replace
the old APIs in PF cmdq module and deletes the old cmdq resource APIs.
Still we kept hclge_cmd_setup_basic_desc name as a seam API to avoid too
many meaningless replacement.

The PF and VF cmdq module resource allocate/free/query APIs are almost the
same espect the suffixes of API names. These same implementations bring
double development and bugfix work.
This patch creates common cmdq resource allocate/free/query APIs called by
PF and VF cmdq init/uninit APIs. The next patch will use the new unified
APIs to replace init/uninit APIs.

This patch firstly uses new hardware description struct hclge_comm_hw as
child member of hclgevf_hw and deletes the old hardware description child
members. All the hclgevf_hw variables used in VF module is modified
according to the new hclgevf_hw.
Secondly hclgevf_cmd_send is refactored to use hclge_comm_cmd_send APIs.
The old functions called by hclgevf_cmd_send are all deleted. Still we kept
hclgevf_cmd_send to avoid too many meaningless modifications.

This patch create new set of unified hclge_comm_cmd_send APIs for PF and VF
cmdq module. Subfunctions called by hclge_comm_cmd_send are also created
include cmdq result check, cmdq return code conversion and ring space
opertaion APIs.
These new common cmdq APIs will be used to replace the old PF and VF cmdq
APIs in next patches.

This patch use new common struct hclge_desc to replace struct hclgevf_desc
in VF cmdq module and then delete the old struct hclgevf_desc.

Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq
hardware information needed by hclge(vf)_cmd_send. There are a little
differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring.
It is redundent to use two sets of structures to support same functions.
So this patch creates new set of common cmdq hardware description
structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct
hclge_desc is still kept to avoid too many meaningless replacement.
These new structures will be used to unify hclge(vf)_hw structures in PF
and VF cmdq APIs in next patches.

Currently we plan to refactor PF and VF cmdq module. A new file folder
hns3_common will be created to store new common APIs used by PF and VF
cmdq module. Thus the PF and VF compilation process will both depends on
the hns3_common. This may cause parallel building problems if we add a new
makefile building unit.
So this patch combined the PF and VF makefile scripts to the top level
makefile to support the new hns3_common which will be created in the next
patch.
