Subject: [PATCH net-next 0/9] net: Kernel side filtering for route dumps
Date: Thu, 11 Oct 2018 08:06:18 -0700 [thread overview]
Message-ID: <20181011150627.4010-1-dsahern@kernel.org> (raw)
From: David Ahern <dsahern@gmail•com>
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.
David Ahern (9):
net: Add struct for fib dump filter
net/ipv4: Plumb support for filtering route dumps
net/ipv6: Plumb support for filtering route dumps
net/mpls: Plumb support for filtering route dumps
net: Plumb support for filtering ipv4 and ipv6 multicast route dumps
net: Enable kernel side filtering of route dumps
net/mpls: Handle kernel side filtering of route dumps
net/ipv6: Bail early if user only wants cloned entries
net/ipv4: Bail early if user only wants prefix entries
