pull-request: bpf-next 2024-04-29

We've added 147 non-merge commits during the last 32 day(s) which contain
a total of 158 files changed, 9400 insertions(+), 2213 deletions(-).

The main changes are:

1) Add an internal-only BPF per-CPU instruction for resolving per-CPU
   memory addresses and implement support in x86 BPF JIT. This allows
   inlining per-CPU array and hashmap lookups
   and the bpf_get_smp_processor_id() helper, from Andrii Nakryiko.

2) Add BPF link support for sk_msg and sk_skb programs, from Yonghong Song.

3) Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
   atomics in bpf_arena which can be JITed as a single x86 instruction,
   from Alexei Starovoitov.

4) Add support for passing mark with bpf_fib_lookup helper,
   from Anton Protopopov.

5) Add a new bpf_wq API for deferring events and refactor sleepable
   bpf_timer code to keep common code where possible,
   from Benjamin Tissoires.

6) Fix BPF_PROG_TEST_RUN infra with regards to bpf_dummy_struct_ops programs
   to check when NULL is passed for non-NULLable parameters,
   from Eduard Zingerman.

7) Harden the BPF verifier's and/or/xor value tracking,
   from Harishankar Vishwanathan.

8) Introduce crypto kfuncs to make BPF programs able to utilize the kernel
   crypto subsystem, from Vadim Fedorenko.

9) Various improvements to the BPF instruction set standardization doc,
   from Dave Thaler.

10) Extend libbpf APIs to partially consume items from the BPF ringbuffer,
    from Andrea Righi.

11) Bigger batch of BPF selftests refactoring to use common network helpers
    and to drop duplicate code, from Geliang Tang.

12) Support bpf_tail_call_static() helper for BPF programs with GCC 13,
    from Jose E. Marchesi.

13) Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
    program to have code sections where preemption is disabled,
    from Kumar Kartikeya Dwivedi.

14) Allow invoking BPF kfuncs from BPF_PROG_TYPE_SYSCALL programs,
    from David Vernet.

15) Extend the BPF verifier to allow different input maps for a given
    bpf_for_each_map_elem() helper call in a BPF program, from Philo Lu.

16) Add support for PROBE_MEM32 and bpf_addr_space_cast instructions
    for riscv64 and arm64 JITs to enable BPF Arena, from Puranjay Mohan.

17) Shut up a false-positive KMSAN splat in interpreter mode by unpoison
    the stack memory, from Martin KaFai Lau.

18) Improve xsk selftest coverage with new tests on maximum and minimum
    hardware ring size configurations, from Tushar Vyavahare.

19) Various ReST man pages fixes as well as documentation and bash completion
    improvements for bpftool, from Rameez Rehman & Quentin Monnet.

20) Fix libbpf with regards to dumping subsequent char arrays,
    from Quentin Deslandes.

b17181a88f dt-bindings: net: pse-pd: Add another way of describing several PSE PIs
PSE PI setup may encompass multiple PSE controllers or auxiliary circuits
that collectively manage power delivery to one Ethernet port.
Such configurations might support a range of PoE standards and require
the capability to dynamically configure power delivery based on the
operational mode (e.g., PoE2 versus PoE4) or specific requirements of
connected devices. In these instances, a dedicated PSE PI node becomes
essential for accurately documenting the system architecture. This node
would serve to detail the interactions between different PSE controllers,
the support for various PoE modes, and any additional logic required to
coordinate power delivery across the network infrastructure.

The old usage of "#pse-cells" is unsuficient as it carries only the PSE PI
index information.

9be9567a7c net: pse-pd: Add support for PSE PIs
The Power Sourcing Equipment Power Interface (PSE PI) plays a pivotal role
in the architecture of Power over Ethernet (PoE) systems. It is essentially
a blueprint that outlines how one or multiple power sources are connected
to the eight-pin modular jack, commonly known as the Ethernet RJ45 port.
This connection scheme is crucial for enabling the delivery of power
alongside data over Ethernet cables.

This patch adds support for getting the PSE controller node through PSE PI
device subnode.

This supports adds a way to get the PSE PI id from the pse_pi devicetree
subnode of a PSE controller node simply by reading the reg property.

b58be8db63 ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL
In the current PSE interface for Ethernet Power Equipment, support is
limited to PoDL. This patch extends the interface to accommodate the
objects specified in IEEE 802.3-2022 145.2 for Power sourcing
Equipment (PSE).

The following objects are now supported and considered mandatory:
- IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus
- IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState
- IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl

To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar
names but distinct values, we have followed the suggestion of Oleksij
Rempel and Andrew Lunn to maintain separate naming schemes for each,
using c33 (clause 33) prefix for "PoE PSE".
You can find more details in the discussion threads here:

f5c12105c1 mm,page_owner: fix refcount imbalance
Current code does not contemplate scenarios were an allocation and free
operation on the same pages do not handle it in the same amount at once. 
To give an example, page_alloc_exact(), where we will allocate a page of
enough order to stafisfy the size request, but we will free the remainings
right away.

In the above example, we will increment the stack_record refcount only
once, but we will decrease it the same number of times as number of unused
pages we have to free.  This will lead to a warning because of refcount
imbalance.

Fix this by recording the number of base pages in the refcount field.

8d939ae349 docs: verify/bisect: stable regressions: first stable, then mainline
Rearrange the instructions so that readers facing a regression within a
stable or longterm series first test its latest release before testing
mainline. This is less scary for some people. It also reduces the chance
that something goes sideways for readers that compile their first
kernel, as mainline can cause slightly more trouble.

  - Work around an APIC emulation bug when the kernel is built with

  - Follow up x86 topology fixes.
 
 Note that there's minor cleanups included in the BHI fixes,
 which we'd normally delay to the next merge window, but the
 BHI mitigations code is new and will be backported widely,
 so we thought it would be better to have a unified codebase
 at this stage. (Let me know if that assumption is wrong and
 I'll rebase it.)

Fixes for v6.9

Display:
- Fixes for PM refcount leak when DP goes to disconnected state and
  also when link training fails. This is also one of the issues found
  with the pm runtime series
- Add missing newlines to prints in msm_fb and msm_kms
- Change permissions of some dpu debugfs entries which write to const
  data from catalog to read-only to avoid protection faults
- Fix the interface table for the catalog of X1E80100. This is an
  important fix to bringup DP for X1E80100.
- Logging fix to print the callback symbol in the invalid IRQ message
  case rather than printing when its known to be NULL.
- Bindings fix to add DP node as child of mdss for mdss node
- Minor typo fix in DP driver API which handles port status change

e1dc191dbf bcachefs fixes for v6.9-rc4
Notable user impacting bugs
 
 - On multi device filesystems, recovery was looping in
   btree_trans_too_many_iters(). This checks if a transaction has touched
   too many btree paths (because of iteration over many keys), and isuses
   a restart to drop unneeded paths. But it's now possible for some paths
   to exceed the previous limit without iteration in the interior btree
   update path, since the transaction commit will do alloc updates for
   every old and new btree node, and during journal replay we don't use
   the btree write buffer for locking reasons and thus those updates use
   btree paths when they wouldn't normally.
 
 - Fix a corner case in rebalance when moving extents on a durability=0
   device. This wouldn't be hit when a device was formatted with
   durability=0 since in that case we'll only use it as a write through
   cache (only cached extents will live on it), but durability can now be
   changed on an existing device.
 
 - bch2_get_acl() could rarely forget to handle a transaction restart;
   this manifested as the occasional missing acl that came back after
   dropping caches.
 
 - Fix a major performance regression on high iops multithreaded write
   workloads (only since 6.9-rc1); a previous fix for a deadlock in the
   interior btree update path to check the journal watermark introduced a
   dependency on the state of btree write buffer flushing that we didn't
   want.
 
 - Assorted other repair paths and recovery fixes.
