Merge branch 'next' into for-linus

Prepare input updates for 7.2 merge window.

Merge tag 'bpf-next-7.2' into loongarch-next

LoongArch architecture changes for 7.2 need the bpf changes to add new
features, so merge 'bpf-next-7.2' to create a base.

Merge commit '6beaec3aee9852438b89e4d7891caf5e84d45851' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into gpio/for-current

Merge tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:
"Major changes:

- Recover from BPF arena page faults using a scratch page and add
ptep_try_set() for lockless empty-slot installs on x86 and arm64.

This allows BPF kfuncs to access arena pointers directly.

The 'arena_direct_access' stable branch was created for this work
and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
Kartikeya Dwivedi)

- Lift old restriction and support 6+ arguments in BPF programs and
kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)

Other features and fixes:

- Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
addition of new BTF kinds (Alan Maguire)

- Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei
Starovoitov)

- Refactor object relationship tracking in the verifier and fix a
dynptr use-after-free bug (Amery Hung)

- Harden the signed program loader and reject exclusive maps as inner
maps (Daniel Borkmann)

- Replace the verifier min/max bounds fields with a circular number
(cnum) representation and improve 32->64 bit range refinements
(Eduard Zingerman)

- Introduce the arena library and runtime (libarena) with a buddy
allocator, rbtree and SPMC queue data structures, ASAN support and
a parallel test harness. Allow subprograms to return arena pointers
and switch to a BTF type-tag based __arena annotation (Emil
Tsalapatis)

- Cache build IDs in the sleepable stackmap path and avoid faultable
build ID reads under mm locks (Ihor Solodrai)

- Introduce the tracing_multi link to attach a single BPF program to
many kernel functions at once. Allow specifying the uprobe_multi
target via FD (Jiri Olsa)

- Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
bpf_list_is_first/is_last/empty() (Kaitao Cheng)

- Extend the BPF syscall with common attributes support for
prog_load, btf_load and map_create (Leon Hwang)

- Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu)

- Add sleepable support for tracepoint programs and fix deadlocks in
LRU map due to NMI reentry (Mykyta Yatsenko)

- Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
arrays, enforce write checks for global subprograms (Nuoqi Gui)

- Report the maximum combined stack depth and print a breakdown of
instructions processed per subprogram (Paul Chaignon)

- Add an XDP load-balancer benchmark and arm64 JIT support for stack
arguments (Puranjay Mohan)

- Add kfuncs to traverse over wakeup_sources (Samuel Wu)

- Allow sleepable BPF programs to use LPM trie maps directly (Vlad
Poenaru)

- Many more fixes and cleanups across the verifier, BTF, sockmap,
devmap, bpffs, security hooks, s390/riscv/loongarch JITs,
rqspinlock, libbpf, bpftool, selftests"

Merge branch 'tools-build-bpf-append-extra_cflags-and-host_extracflags'

Leo Yan says:

====================
tools build: bpf: Append EXTRA_CFLAGS and HOST_EXTRACFLAGS

Append EXTRA_CFLAGS and HOST_EXTRACFLAGS to the BPF build.

This mitigates an issue introduced in GCC 15, where a {0} initializer
does not guarantee zeroing the entire union [1].

The common changes under tools to support EXTRA_CFLAGS and
HOST_EXTRACFLAGS are sent separately [2]. As suggested, BPF patches
would be picked up via the bpf tree, so this series only includes BPF
related changes.

bpftool: Pass host flags to bootstrap libbpf

bpftool builds a bootstrap libbpf with HOSTCC, but the libbpf submake can
still inherit target build flags through CFLAGS. This can break cross
builds when host objects are compiled with target-only options.

Since HOST_CFLAGS contains warning options that are not suitable for
building libbpf, use LIBBPF_BOOTSTRAP_CFLAGS with the warning options
removed to build the bootstrap libbpf. Clear EXTRA_CFLAGS so target
extra flags are not mixed into the host bootstrap libbpf build.

bpftool: Restrict feature tests during bootstrap compilation

When the perf build executes 'make -C ../bpf/bpftool bootstrap', bpftool's
Makefile unconditionally evaluated feature checks for llvm, libcap, libbfd,
and disassembler libraries because the bootstrap target was not exempted.

Since the bootstrap bpftool strictly compiles minimal AST parsing and C
code generation logic without linking LLVM or disassembler libraries, these
feature check sub-makes are completely redundant.

Exempt the bootstrap target from non-essential feature tests to eliminate
unneeded sub-make fork overhead during Kbuild startup.

Pull bpf updates from Alexei Starovoitov:

- Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
Zingerman while Martin KaFai Lau reduced his load to Reviwer.

- Lots of fixes everywhere from many first time contributors. Thank you
All.

- Diff stat is dominated by mechanical split of verifier.c into
multiple components:

- backtrack.c: backtracking logic and jump history
- states.c: state equivalence
- cfg.c: control flow graph, postorder, strongly connected
components
- liveness.c: register and stack liveness
- fixups.c: post-verification passes: instruction patching, dead
code removal, bpf_loop inlining, finalize fastcall

8k line were moved. verifier.c still stands at 20k lines.

Further refactoring is planned for the next release.

- Replace dynamic stack liveness with static stack liveness based on
data flow analysis.

This improved the verification time by 2x for some programs and
equally reduced memory consumption. New logic is in liveness.c and
supported by constant folding in const_fold.c (Eduard Zingerman,
Alexei Starovoitov)

bpftool: Allow explicitly skip llvm, libbfd and libcrypto dependencies

Introduce SKIP_LLVM, SKIP_LIBBFD, and SKIP_CRYPTO build flags that let
users build bpftool without these optional dependencies.

bpftool: Allow explicitly skip llvm, libbfd and libcrypto dependencies

Introduce SKIP_LLVM, SKIP_LIBBFD, and SKIP_CRYPTO build flags that let
users build bpftool without these optional dependencies.

SKIP_LLVM=1 skips LLVM even when detected. SKIP_LIBBFD=1 prevents the
libbfd JIT disassembly fallback when LLVM is absent. Together, they
produce a bpftool with no disassembly support.

SKIP_CRYPTO=1 excludes sign.c and removes the -lcrypto link dependency.
Inline stubs in main.h return errors with a clear message if signing
functions are called at runtime.

Use BPFTOOL_WITHOUT_CRYPTO (not HAVE_LIBCRYPTO_SUPPORT) as the C
define, following the BPFTOOL_WITHOUT_SKELETONS naming convention for
bpftool-internal build config, leaving HAVE_LIBCRYPTO_SUPPORT free for
proper feature detection in the future.

All three flags are propagated through the selftests Makefile to bpftool
sub-builds.
