Subject: pull-request: bpf-next 2024-10-31

Hi David, hi Jakub, hi Paolo, hi Eric,

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

We've added 13 non-merge commits during the last 16 day(s) which contain
a total of 16 files changed, 710 insertions(+), 668 deletions(-).

There's a small merge conflict between f91b256644ea ("selftests/bpf: Add
test for kfunc module order") in net-next tree and c3566ee6c66c
("selftests/bpf: remove test_tcp_check_syncookie") from bpf-next/net.

Resolve as follows in tools/testing/selftests/bpf/Makefile so that end
result looks like:

 # Compile but not part of 'make run_tests'
 TEST_GEN_PROGS_EXTENDED = \
	bench \
	bpf_testmod.ko \
	bpf_test_modorder_x.ko \
	bpf_test_modorder_y.ko \
	bpf_test_no_cfi.ko \
	flow_dissector_load \
	runqslower \
	test_cpp \
	test_flow_dissector \
	test_lirc_mode2_user \
	veristat \
	xdp_features \
	xdp_hw_metadata \
	xdp_redirect_multi \
	xdp_synproxy \
	xdping \
	xskxceiver

The main changes are:

1) Optimize and homogenize bpf_csum_diff helper for all archs and also
   add a batch of new BPF selftests for it, from Puranjay Mohan.

2) Rewrite and migrate the test_tcp_check_syncookie.sh BPF selftest
   into test_progs so that it can be run in BPF CI, from Alexis Lothoré.

3) Two BPF sockmap selftest fixes, from Zijian Zhang.

4) Small XDP synproxy BPF selftest cleanup to remove IP_DF check,
   from Vincent Li.
