Linux kernel source tree

Roberto Sassu says: ==================== From: Roberto Sassu <roberto.sassu@huawei.com> Add the _opts variant for bpf_*_get_fd_by_id() functions, to be able to pass to the kernel more options, when requesting a fd of an eBPF object. Pass the options through a newly introduced structure, bpf_get_fd_by_id_opts, which currently contains open_flags (the other two members are for compatibility and for padding). open_flags allows the caller to request specific permissions to access a map (e.g. read-only). This is useful for example in the situation where a map is write-protected. Besides patches 2-6, which introduce the new variants and the data structure, patch 1 fixes the LIBBPF_1.0.0 declaration in libbpf.map. Changelog v1: - Don't CC stable kernel mailing list for patch 1 (suggested by Andrii) - Rename bpf_get_fd_opts struct to bpf_get_fd_by_id_opts (suggested by Andrii) - Move declaration of _opts variants after non-opts variants (suggested by Andrii) - Correctly initialize bpf_map_info, fix style issues, use map from skeleton, check valid fd in the test (suggested by Andrii) - Rename libbpf_get_fd_opts test to libbpf_get_fd_by_id_opts ==================== Signed-off-by: Andrii Nakryiko <andrii@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.
