Daniel Borkmann says: ==================== 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. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: s390/bpf: Fix unwinding past the trampoline s390/bpf: Fix clobbering the caller's backchain in the trampoline selftests/bpf: Add testcase for async callback return value failure bpf: Fix verifier log for async callback return values xdp: Fix zero-size allocation warning in xskq_create() riscv, bpf: Track both a0 (RISC-V ABI) and a5 (BPF) return values riscv, bpf: Sign-extend return values selftests/bpf: Make seen_tc* variable tests more robust selftests/bpf: Test query on empty mprog and pass revision into attach selftests/bpf: Adapt assert_mprog_count to always expect 0 count selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall bpf: Refuse unused attributes in bpf_prog_{attach,detach} bpf: Handle bpf_mprog_query with NULL entry bpf: Fix BPF_PROG_QUERY last field check ==================== Link: https://lore.kernel.org/r/20231010223610.3984-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
