2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach5-3/+10
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2018-03-20FIB Interpose SourceNeale Ranns18-3987/+5041
The interpose source allows the source/provider to insert/interpose a DPO in the forwarding chain of the FIB entry ahead of the forwarding provided by the next best source. For example if the API source (i.e the 'control plane') has provided an adjacency for forwarding, then an interpose source (e.g. a monitoring service) couold interpose a replicatte DPO to copy the traffic to another location AND forward using the API's adjacency. To use the interose feature an existing source (i.e FIB_SOURCE_PLUGIN_HI) cn specifiy as a flag FIB_ENTRY_FLAG_INTERPOSE and provide a DPO to interpose. One might also consider using interpose in conjunction with FIB_ENTRY_FLAG_COVER_INHERIT to ensure the interpose object affects all prefixes in the sub-tree.

2017-10-05Distributed Virtual Router SupportNeale Ranns5-100/+100
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.
