Toke Høiland-Jørgensen says: ==================== This series adds support for atomically replacing the XDP program loaded on an interface. This is achieved by means of a new netlink attribute that can specify the expected previous program to replace on the interface. If set, the kernel will compare this "expected fd" attribute with the program currently loaded on the interface, and reject the operation if it does not match. With this primitive, userspace applications can avoid stepping on each other's toes when simultaneously updating the loaded XDP program. Changelog: v4: - Switch back to passing FD instead of ID (Andrii) - Rename flag to XDP_FLAGS_REPLACE (for consistency with other similar uses) v3: - Pass existing ID instead of FD (Jakub) - Use opts struct for new libbpf function (Andrii) v2: - Fix checkpatch nits and add .strict_start_type to netlink policy (Jakub) ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

README
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.
