Eli Britstein 8c4dc42bf6 net/mlx5e: Support multiple encapsulations for a TC flow
Currently a flow is associated with a single encap structure. The FW
extended destination features enables the driver to associate a flow
with multiple encap instances.

Change the encap id field from a flow scope to a per destination value
in the flow attributes struct. Use the encaps array to associate a flow
table entry with multiple encap entries.

Update the neigh logic to offload only if all encapsulations used in a
flow are connected, and un-offload upon the first one disconnected.

Note that the driver can now support up to two encap destinations.

Eli Britstein 1cc26d74bb net/mlx5e: Support header rewrite actions with remote port mirroring
A rule with the following actions is split to a two level FDB:
1. Forward to local mirror vport
2. Header rewrite
3. Forward to local vport
In the first level flow table, forward the packet to the local port and
forward the packet to the second level flow table for header rewrite and
local port forwarding. This configuration fails when mirroring to a
remote encapsulated destination because currently an FTE cannot support
encap and table destinations.

Use the extended destination capabilities to configure the first level
flow table with a multi-destination FTE to the uplink and second level
table and the second level flow table for the header rewrite and local
port forwarding.

Eli Britstein 38c9d2697b net/mlx5e: Replace the split logic with extended destination
Currently the FTE encap flag applies to all destinations.
To support mirroring encapsulated traffic to a local port the driver
split the two destinations to two flow table entries:
Table#0: - FWD to the local vport
         - Goto table#1
Table#1: - Encap and FWD to wire
The firmware extended destination capabilities enable the driver to set
an encapsulation flag per destination.

Remove the split logic and use the extended destination mechanism
instead.

Note that split technique is still required for pedit and VLAN push
scenarios.

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-12-11

The following pull-request contains BPF updates for your *net-next* tree.

It has three minor merge conflicts, resolutions:

1) tools/testing/selftests/bpf/test_verifier.c

 Take first chunk with alignment_prevented_execution.

2) net/core/filter.c

  [...]
  case bpf_ctx_range_ptr(struct __sk_buff, flow_keys):
  case bpf_ctx_range(struct __sk_buff, wire_len):
        return false;
  [...]

3) include/uapi/linux/bpf.h

  Take the second chunk for the two cases each.

The main changes are:

1) Add support for BPF line info via BTF and extend libbpf as well
   as bpftool's program dump to annotate output with BPF C code to
   facilitate debugging and introspection, from Martin.

2) Add support for BPF_ALU | BPF_ARSH | BPF_{K,X} in interpreter
   and all JIT backends, from Jiong.

3) Improve BPF test coverage on archs with no efficient unaligned
   access by adding an "any alignment" flag to the BPF program load
   to forcefully disable verifier alignment checks, from David.

4) Add a new bpf_prog_test_run_xattr() API to libbpf which allows for
   proper use of BPF_PROG_TEST_RUN with data_out, from Lorenz.

5) Extend tc BPF programs to use a new __sk_buff field called wire_len
   for more accurate accounting of packets going to wire, from Petar.

6) Improve bpftool to allow dumping the trace pipe from it and add
   several improvements in bash completion and map/prog dump,
   from Quentin.

7) Optimize arm64 BPF JIT to always emit movn/movk/movk sequence for
   kernel addresses and add a dedicated BPF JIT backend allocator,
   from Ard.

8) Add a BPF helper function for IR remotes to report mouse movements,
   from Sean.

9) Various cleanups in BPF prog dump e.g. to make UAPI bpf_prog_info
   member naming consistent with existing conventions, from Yonghong
   and Song.

10) Misc cleanups and improvements in allowing to pass interface name
    via cmdline for xdp1 BPF example, from Matteo.

11) Fix a potential segfault in BPF sample loader's kprobes handling,
    from Daniel T.

12) Fix SPDX license in libbpf's README.rst, from Andrey.

David Ahern 8cc196d6ef neighbor: gc_list changes should be protected by table lock
Adding and removing neighbor entries to / from the gc_list need to be
done while holding the table lock; a couple of places were missed in the
original patch.

Move the list_add_tail in neigh_alloc to ___neigh_create where the lock

to/from PERMANENT state, add lock/unlock around the gc_list changes in
neigh_change_state rather than extending the lock hold around all

Alexei Starovoitov aa570ff4fd Merge branch 'rename-info_cnt-to-nr_info'
Yonghong Song says:

====================
Before func_info and line_info are added to the kernel, there are several
fields in structure bpf_prog_info specifying the "count" of a user buffer, e.g.,
        __u32 nr_jited_ksyms;
        __u32 nr_jited_func_lens;
The naming convention has the prefix "nr_".

The func_info and line_info support added several fields
        __u32 func_info_cnt;
        __u32 line_info_cnt;
        __u32 jited_line_info_cnt;
to indicate the "count" of buffers func_info, line_info and jited_line_info.
The original intention is to keep the field names the same as those in
structure bpf_attr, so it will be clear that the "count" returned to user
space will be the same as the one passed to the kernel during prog load.

Unfortunately, the field names *_info_cnt are not consistent with
other existing fields in bpf_prog_info.
This patch set renamed the fields *_info_cnt to nr_*_info
to keep naming convention consistent.

Yonghong Song 11d8b82d22 bpf: rename *_info_cnt to nr_*_info in bpf_prog_info
In uapi bpf.h, currently we have the following fields in
the struct bpf_prog_info:
	__u32 func_info_cnt;
	__u32 line_info_cnt;
	__u32 jited_line_info_cnt;
The above field names "func_info_cnt" and "line_info_cnt"
also appear in union bpf_attr for program loading.

The original intention is to keep the names the same
between bpf_prog_info and bpf_attr
so it will imply what we returned to user space will be
the same as what the user space passed to the kernel.

Such a naming convention in bpf_prog_info is not consistent
with other fields like:
        __u32 nr_jited_ksyms;
        __u32 nr_jited_func_lens;

This patch made this adjustment so in bpf_prog_info
newly introduced *_info_cnt becomes nr_*_info.

Eli Britstein a2c6162b12 net/mlx5: Support extended destination format in flow steering command
Update the flow steering command formatting according to the extended
destination API.
Note that the FW dictates that multi destination FTEs that involve at
least one encap must use the extended destination format, while single
destination ones must use the legacy format.
Using extended destination format requires FW support. Check for its
capabilities and return error if not supported.

Extended destinations provide the ability to configure different

Oz Shlomo 5886a96ad1 net/mlx5: Revise gre and nvgre key formats
GRE RFC defines a 32 bit key field. NVGRE RFC splits the 32 bit
key field to 24 bit VSID (gre_key_h) and 8 bit flow entropy (gre_key_l).

Define the two key parsing alternatives in a union, thus enabling both
access methods.

Additionally, when HW signals an unexpected cable status, it is reported
now rather than ignored. And status counter is now updated on errors.

Eric Dumazet d8ed257f31 tcp: handle EOR and FIN conditions the same in tcp_tso_should_defer()
In commit f9bfe4e6a9 ("tcp: lack of available data can also cause
TSO defer") we moved the test in tcp_tso_should_defer() for packets
with a FIN flag, and we mentioned that the same would be done
later for EOR flag.

Both flags should be handled at the same time, after all other
heuristics have been considered. They both mean that no more bytes
can be added to this skb by an application.
