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 'security-propagate-caller-information-in-bpf-hooks'

Blaise Boscaccy says:

====================
While trying to implement an eBPF gatekeeper program, we ran into an
issue whereas the LSM hooks are missing some relevant data.

Certain subcommands passed to the bpf() syscall can be invoked from
either the kernel or userspace. Additionally, some fields in the
bpf_attr struct contain pointers, and depending on where the
subcommand was invoked, they could point to either user or kernel
memory. One example of this is the bpf_prog_load subcommand and its
fd_array. This data is made available and used by the verifier but not
made available to the LSM subsystem. This patchset simply exposes that
information to applicable LSM hooks.

Change list:
- v6 -> v7
- use gettid/pid in lieu of getpid/tgid in test condition
- v5 -> v6
- fix regression caused by is_kernel renaming
- simplify test logic
- v4 -> v5
- merge v4 selftest breakout patch back into a single patch
- change "is_kernel" to "kernel"
- add selftest using new kernel flag
- v3 -> v4
- split out selftest changes into a separate patch
- v2 -> v3
- reorder params so that the new boolean flag is the last param
- fixup function signatures in bpf selftests
- v1 -> v2
- Pass a boolean flag in lieu of bpfptr_t

selftests/bpf: Add a kernel flag test for LSM bpf hook

This test exercises the kernel flag added to security_bpf by
effectively blocking light-skeletons from loading while allowing
normal skeletons to function as-is. Since this should work with any
arbitrary BPF program, an existing program from LSKELS_EXTRA was
used as a test payload.
