Pull bpf updates from Alexei Starovoitov:
"For this merge window we're splitting BPF pull request into three for
higher visibility: main changes, res_spin_lock, try_alloc_pages.

These are the main BPF changes:

- Add DFA-based live registers analysis to improve verification of
programs with loops (Eduard Zingerman)

- Introduce load_acquire and store_release BPF instructions and add
x86, arm64 JIT support (Peilin Ye)

- Fix loop detection logic in the verifier (Eduard Zingerman)

- Drop unnecesary lock in bpf_map_inc_not_zero() (Eric Dumazet)

- Add kfunc for populating cpumask bits (Emil Tsalapatis)

- Convert various shell based tests to selftests/bpf/test_progs
format (Bastien Curutchet)

- Allow passing referenced kptrs into struct_ops callbacks (Amery
Hung)

- Add a flag to LSM bpf hook to facilitate bpf program signing
(Blaise Boscaccy)

- Track arena arguments in kfuncs (Ihor Solodrai)

- Add copy_remote_vm_str() helper for reading strings from remote VM
and bpf_copy_from_user_task_str() kfunc (Jordan Rome)

- Add support for timed may_goto instruction (Kumar Kartikeya
Dwivedi)

- Allow bpf_get_netns_cookie() int cgroup_skb programs (Mahe Tardy)

- Reduce bpf_cgrp_storage_busy false positives when accessing cgroup
local storage (Martin KaFai Lau)

- Introduce bpf_dynptr_copy() kfunc (Mykyta Yatsenko)

- Allow retrieving BTF data with BTF token (Mykyta Yatsenko)

- Add BPF kfuncs to set and get xattrs with 'security.bpf.' prefix
(Song Liu)

- Reject attaching programs to noreturn functions (Yafang Shao)

- Introduce pre-order traversal of cgroup bpf programs (Yonghong
Song)"

Merge branch 'support-freplace-prog-from-user-namespace'

Mykyta Yatsenko says:

====================
Support freplace prog from user namespace

From: Mykyta Yatsenko <yatsenko@meta.com>

Freplace programs can't be loaded from user namespace, as
bpf_program__set_attach_target() requires searching for target prog BTF,
which is locked under CAP_SYS_ADMIN.
This patch set enables this use case by:
1. Relaxing capable check in bpf's BPF_BTF_GET_FD_BY_ID, check for CAP_BPF
instead of CAP_SYS_ADMIN, support BPF token in attr argument.
2. Pass BPF token around libbpf from bpf_program__set_attach_target() to
bpf syscall where capable check is.
3. Validate positive/negative scenarios in selftests

This patch set is enabled by the recent libbpf change[1], that
introduced bpf_object__prepare() API. Calling bpf_object__prepare() for
freplace program before bpf_program__set_attach_target() initializes BPF
token, which is then passed to bpf syscall by libbpf.

selftests/bpf: Test freplace from user namespace

Add selftests to verify that it is possible to load freplace program
from user namespace if BPF token is initialized by bpf_object__prepare
before calling bpf_program__set_attach_target.
Negative test is added as well.

Modified type of the priv_prog to xdp, as kprobe did not work on aarch64
and s390x.
