Andrii Nakryiko says: ==================== Fix libbpf's bpf_object and BPF subskel interoperability Fix libbpf's global data map mmap()'ing logic to make BPF objects loaded through generic bpf_object__load() API interoperable with BPF subskeleton instantiated from such BPF object. The issue is in re-mmap()'ing of global data maps after BPF object is loaded into kernel, which is currently done in BPF skeleton-specific code, and should instead be done in generic and common bpf_object_load() logic. See patch #2 for the fix, patch #3 for the selftests. Patch #1 is preliminary fix for existing spin_lock selftests which currently works by accident. ==================== Link: https://lore.kernel.org/r/20241023043908.3834423-1-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.
