Merge tag 'bpf-next-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

- Convert selftests/bpf/test_tc_edt and test_tc_tunnel from .sh to
test_progs runner (Alexis Lothoré)

- Convert selftests/bpf/test_xsk to test_progs runner (Bastien
Curutchet)

- Replace bpf memory allocator with kmalloc_nolock() in
bpf_local_storage (Amery Hung), and in bpf streams and range tree
(Puranjay Mohan)

- Introduce support for indirect jumps in BPF verifier and x86 JIT
(Anton Protopopov) and arm64 JIT (Puranjay Mohan)

- Remove runqslower bpf tool (Hoyeon Lee)

- Fix corner cases in the verifier to close several syzbot reports
(Eduard Zingerman, KaFai Wan)

- Several improvements in deadlock detection in rqspinlock (Kumar
Kartikeya Dwivedi)

- Implement "jmp" mode for BPF trampoline and corresponding
DYNAMIC_FTRACE_WITH_JMP. It improves "fexit" program type performance
from 80 M/s to 136 M/s. With Steven's Ack. (Menglong Dong)

- Add ability to test non-linear skbs in BPF_PROG_TEST_RUN (Paul
Chaignon)

- Do not let BPF_PROG_TEST_RUN emit invalid GSO types to stack (Daniel
Borkmann)

- Generalize buildid reader into bpf_dynptr (Mykyta Yatsenko)

- Optimize bpf_map_update_elem() for map-in-map types (Ritesh
Oedayrajsingh Varma)

- Introduce overwrite mode for BPF ring buffer (Xu Kuohai)

selftests/bpf: Add overwrite mode test for BPF ring buffer

Add overwrite mode test for BPF ring buffer. The test creates a BPF ring
buffer in overwrite mode, then repeatedly reserves and commits records
to check if the ring buffer works as expected both before and after
overwriting occurs.
