====================
pull-request: bpf 2023-10-11

We've added 14 non-merge commits during the last 5 day(s) which contain
a total of 12 files changed, 398 insertions(+), 104 deletions(-).

The main changes are:

1) Fix s390 JIT backchain issues in the trampoline code generation which
   previously clobbered the caller's backchain, from Ilya Leoshkevich.

2) Fix zero-size allocation warning in xsk sockets when the configured
   ring size was close to SIZE_MAX, from Andrew Kanner.

3) Fixes for bpf_mprog API that were found when implementing support
   in the ebpf-go library along with selftests, from Daniel Borkmann
   and Lorenz Bauer.

4) Fix riscv JIT to properly sign-extend the return register in programs.
   This fixes various test_progs selftests on riscv, from Björn Töpel.

5) Fix verifier log for async callback return values where the allowed
   range was displayed incorrectly, from David Vernet.

README

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.
