Merge tag 'bpf-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

- Support pulling non-linear xdp data with bpf_xdp_pull_data() kfunc
(Amery Hung)

Applied as a stable branch in bpf-next and net-next trees.

- Support reading skb metadata via bpf_dynptr (Jakub Sitnicki)

Also a stable branch in bpf-next and net-next trees.

- Enforce expected_attach_type for tailcall compatibility (Daniel
Borkmann)

the verifier (Eduard Zingerman)

This is a significant change in the verification logic. More details,
motivation, long term plans are in the cover letter/merge commit.

- Support signed BPF programs (KP Singh)

This is another major feature that took years to materialize.

Algorithm details are in the cover letter/marge commit

used in BPF subsystem (Menglong Dong)

- Introduce bpf_task_work_schedule*() kfuncs to schedule deferred
execution of BPF callback in the context of a specific task using the
kernel’s task_work infrastructure (Mykyta Yatsenko)

- Enforce RCU protection for KF_RCU_PROTECTED kfuncs (Kumar Kartikeya
Dwivedi)

selftests/bpf: Remove entries from config.{arch} already present in config

`config.{arch}` had entries already present in `config`.

When generating the config used by vmtest, concatenate the `config` file
with the `config.{arch}` one, making those entries duplicated, so remove
those duplications.

Use the following command to get the differences:

$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.x86_64) <(sort tools/testing/selftests/bpf/config)
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.aarch64) <(sort tools/testing/selftests/bpf/config)
