====================
pull-request: bpf-next 2023-11-21

We've added 85 non-merge commits during the last 12 day(s) which contain
a total of 63 files changed, 4464 insertions(+), 1484 deletions(-).

The main changes are:

1) Huge batch of verifier changes to improve BPF register bounds logic
   and range support along with a large test suite, and verifier log
   improvements, all from Andrii Nakryiko.

2) Add a new kfunc which acquires the associated cgroup of a task within
   a specific cgroup v1 hierarchy where the latter is identified by its id,
   from Yafang Shao.

3) Extend verifier to allow bpf_refcount_acquire() of a map value field
   obtained via direct load which is a use-case needed in sched_ext,
   from Dave Marchevsky.

4) Fix bpf_get_task_stack() helper to add the correct crosstask check
   for the get_perf_callchain(), from Jordan Rome.

5) Fix BPF task_iter internals where lockless usage of next_thread()
   was wrong. The rework also simplifies the code, from Oleg Nesterov.

6) Fix uninitialized tail padding via LIBBPF_OPTS_RESET, and another
   fix for certain BPF UAPI structs to fix verifier failures seen
   in bpf_dynptr usage, from Yonghong Song.

7) Add BPF selftest fixes for map_percpu_stats flakes due to per-CPU BPF
   memory allocator not being able to allocate per-CPU pointer successfully,
   from Hou Tao.

8) Add prep work around dynptr and string handling for kfuncs which
   is later going to be used by file verification via BPF LSM and fsverity,
   from Song Liu.

9) Improve BPF selftests to update multiple prog_tests to use ASSERT_*
   macros, from Yuran Pereira.

10) Optimize LPM trie lookup to check prefixlen before walking the trie,
    from Florian Lehner.

11) Consolidate virtio/9p configs from BPF selftests in config.vm file
    given they are needed consistently across archs, from Manu Bretelle.

12) Small BPF verifier refactor to remove register_is_const(),
    from Shung-Hsi Yu.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
