pull-request: bpf-next 2025-09-23
We've added 9 non-merge commits during the last 33 day(s) which contain
a total of 10 files changed, 480 insertions(+), 53 deletions(-).
The main changes are:
1) A new bpf_xdp_pull_data kfunc that supports pulling data from
a frag into the linear area of a xdp_buff, from Amery Hung.
This includes changes in the xdp_native.bpf.c selftest, which
Nimrod's future work depends on.
It is a merge from a stable branch 'xdp_pull_data' which has
also been merged to bpf-next.
There is a conflict with recent changes in 'include/net/xdp.h'
in the net-next tree that will need to be resolved.
2) A compiler warning fix when CONFIG_NET=n in the recent dynptr
skb_meta support, from Jakub Sitnicki.
