There are some unanswered questions on the list, and we don't
have any docs. Given the lack of replies so far and the fact
that v6.8 merge window has started - let's revert this and
revisit for v6.9.

      net: ethtool: reject unsupported RSS input xfrm values · 948f97f9
      Ahmed Zaki authored 
      RXFH input_xfrm currently has three supported values: 0 (clear all),
symmetric_xor and NO_CHANGE.

Reject any other value sent from user-space.

Fixes: 13e59344 ("net: ethtool: add support for symmetric-xor RSS hash")

      selftests: forwarding: Avoid failures to source net/lib.sh · 2114e833
      Benjamin Poirier authored 
      The expression "source ../lib.sh" added to net/forwarding/lib.sh in commit
25ae948b ("selftests/net: add lib.sh") does not work for tests outside
net/forwarding which source net/forwarding/lib.sh (1). It also does not
work in some cases where only a subset of tests are exported (2).

Avoid the problems mentioned above by replacing the faulty expression with
a copy of the content from net/lib.sh which is used by files under
net/forwarding.

A more thorough solution which avoids duplicating content between
net/lib.sh and net/forwarding/lib.sh has been posted here:
https://lore.kernel.org/netdev/20231222135836.992841-1-bpoirier@nvidia.com/

The approach in the current patch is a stopgap solution to avoid submitting
large changes at the eleventh hour of this development cycle.

Example of problem 1)

tools/testing/selftests/drivers/net/bonding$ ./dev_addr_lists.sh
./net_forwarding_lib.sh: line 41: ../lib.sh: No such file or directory
TEST: bonding cleanup mode active-backup                            [ OK ]
TEST: bonding cleanup mode 802.3ad                                  [ OK ]
TEST: bonding LACPDU multicast address to slave (from bond down)    [ OK ]
TEST: bonding LACPDU multicast address to slave (from bond up)      [ OK ]

An error message is printed but since the test does not use functions from
net/lib.sh, the test results are not affected.

Example of problem 2)

tools/testing/selftests$ make install TARGETS="net/forwarding"
tools/testing/selftests$ cd kselftest_install/net/forwarding/
tools/testing/selftests/kselftest_install/net/forwarding$ ./pedit_ip.sh veth{0..3}
lib.sh: line 41: ../lib.sh: No such file or directory

        Expected to get 10 packets, but got .

TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1              [FAIL]
        Expected to get 10 packets, but got .

In this case, the test results are affected.

====================
pull-request: bpf-next 2024-01-05

We've added 40 non-merge commits during the last 2 day(s) which contain
a total of 73 files changed, 1526 insertions(+), 951 deletions(-).

The main changes are:

1) Fix a memory leak when streaming AF_UNIX sockets were inserted
   into multiple sockmap slots/maps, from John Fastabend.

2) Fix gotol in s390 BPF JIT with large offsets, from Ilya Leoshkevich.

3) Fix reattachment branch in bpf_tracing_prog_attach() and reject
   the request if there is no valid attach_btf, from Jiri Olsa.

4) Remove deprecated bpfilter kernel leftovers given the project
   is developed in user space (https://github.com/facebook/bpfilter),
   from Quentin Deslandes.

5) Relax tracing BPF program recursive attach rules given right now
   it is not possible to create tracing program call cycles,
   from Dmitrii Dolgov.

6) Fix excessive memory consumption for the bpf_global_percpu_ma
   for systems with a large number of CPUs, from Yonghong Song.

7) Small x86 BPF JIT cleanup to reuse emit_nops instead of open-coding
   memcpy of x86_nops, from Leon Hwang.

8) Follow-up for libbpf to support __arg_ctx global function argument tag
   semantics to complement the merged kernel side, from Andrii Nakryiko.

9) Introduce "volatile compare" macros for BPF selftests in order
   to make the latter more robust against compiler optimization,
   from Alexei Starovoitov.

10) Small simplification in verifier's size checking of helper accesses
    along with additional selftests, from Andrei Matei.
