Andrii Nakryiko says: ==================== Add bpf_map__set_autocreate() API which is a BPF map counterpart of bpf_program__set_autoload() and serves similar goal of allowing to build more flexible CO-RE applications. See patch #3 for example scenarios in which the need for such API came up previously. Patch #1 is a follow-up patch to previous patch set adding verifier log fixup logic, making sure bpf_core_format_spec()'s return result is used for something useful. Patch #2 is a small refactoring to avoid unnecessary verbose memory management around obj->maps array. Patch #3 adds and API and corresponding BPF verifier log fix up logic to provide human-comprehensible error message with useful details. Patch #4 adds a simple selftest validating both the API itself and libbpf's log fixup logic for it. ==================== 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 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.
