David Ahern says: ==================== net: Kernel side filtering for route dumps Implement kernel side filtering of route dumps by protocol (e.g., which routing daemon installed the route), route type (e.g., unicast), table id and nexthop device. iproute2 has been doing this filtering in userspace for years; pushing the filters to the kernel side reduces the amount of data the kernel sends and reduces wasted cycles on both sides processing unwanted data. These initial options provide a huge improvement for efficiently examining routes on large scale systems. v2 - better handling of requests for a specific table. Rather than walking the hash of all tables, lookup the specific table and dump it - refactor mr_rtm_dumproute moving the loop over the table into a helper that can be invoked directly - add hook to return NLM_F_DUMP_FILTERED in DONE message to ensure it is returned even when the dump returns nothing ==================== Signed-off-by: David S.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
