2019-11-10dhcp: ipv6 prefix delegation improvementsDave Barach1-1/+17
Autoconfigure router advertisements for delegated prefixes. Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply, do NOT reset per-delegated-prefix timers. That prevented vpp from sending a solicit to renew the delegation on time. That, in turn caused the RA code to send advertisements with valid_time = preferred_time = 0. That causes almost any downstream client to throw away its delegated address. Miscellaneous changes o src/vnet/ip/ip6_neighbor.c - always memset elements allocated from pools to zero. DGMS. o Remove debug spew from the ipv6 connection-tracker plugin Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I428feccdc47efdc413898600e0d62916928a6eb7

2019-10-29ip: refactor ip4_mtrie to atomically unset leavesjaszha031-4/+6
ip4_mtrie set leaves atomically in set_leaf () and set_root_leaf () but deleted leaves using regular stores in unset_leaf () and unset_root_leaf (). Changed leaf deletion to update mtrie using atomic store-release. Slight performance improvement was observed in benchmarking on Qualcomm and Xeon machines.
