Benjamin Poirier says: ==================== nexthop: Refactor and fix nexthop selection for multipath routes In order to select a nexthop for multipath routes, fib_select_multipath() is used with legacy nexthops and nexthop_select_path_hthr() is used with nexthop objects. Those two functions perform a validity test on the neighbor related to each nexthop but their logic is structured differently. This causes a divergence in behavior and nexthop_select_path_hthr() may return a nexthop that failed the neighbor validity test even if there was one that passed. Refactor nexthop_select_path_hthr() to make it more similar to fib_select_multipath() and fix the problem mentioned above. v1: https://lore.kernel.org/netdev/20230529201914.69828-1-bpoirier@nvidia.com/ ==================== Link: https://lore.kernel.org/r/20230719-nh_select-v2-0-04383e89f868@nvidia.com Signed-off-by: Jakub Kicinski <kuba@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.
