Andrii Nakryiko says: ==================== Fix libbpf BPF skeleton forward/backward compat Fix recently identified (but long standing) bug with handling BPF skeleton forward and backward compatibility. On libbpf side, even though BPF skeleton was always designed to be forward and backwards compatible through recording actual size of constrituents of BPF skeleton itself (map/prog/var skeleton definitions), libbpf implementation did implicitly hard-code those sizes by virtue of using a trivial array access syntax. This issue will only affect libbpf used as a shared library. Statically compiled libbpfs will always be in sync with BPF skeleton, bypassing this problem altogether. This patch set fixes libbpf, but also mitigates the problem for old libbpf versions by teaching bpftool to generate more conservative BPF skeleton, if possible (i.e., if there are no struct_ops maps defined). v1->v2: - fix SOB, add acks, typo fixes (Quentin, Eduard); - improve reporting of skipped map auto-attachment (Alan, Eduard). ==================== Link: https://lore.kernel.org/r/20240708204540.4188946-1-andrii@kernel.org Signed-off-by: Alexei Starovoitov <ast@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 reStructuredText 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.
