Gleb Smirnoff	c8ee75f231	Use network epoch to protect local IPv4 addresses hash. ... The modification to the hash are already naturally locked by in_control_sx. Convert the hash lists to CK lists. Remove the in_ifaddr_rmlock. Assert the network epoch where necessary. Most cases when the hash lookup is done the epoch is already entered. Cover a few cases, that need entering the epoch, which mostly is initial configuration of tunnel interfaces and multicast addresses.

Matt Macy	d7c5a620e2	ifnet: Replace if_addr_lock rwlock with epoch + mutex ... Run on LLNW canaries and tested by pho@ gallatin: Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5 based ConnectX 4-LX NIC, I see an almost 12% improvement in received packet rate, and a larger improvement in bytes delivered all the way to userspace.

Pedro F. Giffuni	fe267a5590	sys: general adoption of SPDX licensing ID tags. ... Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.	2017-11-27 15:23:17 +00:00
Gleb Smirnoff	b365d954cc	Remove last remnants of classful addressing: ... - Remove ia_net, ia_netmask, ia_netbroadcast from struct in_ifaddr. - Remove net.inet.ip.subnetsarelocal, I bet no one need it in 2011. - fix bug when we were not forwarding to a host which matches classful net address. For example router having 192.168.x.y/16 network attached, would not forward traffic to 192.168.*.0, which are legal IPs in CIDR world. - For compatibility, leave autoguessing of mask based on class.
