2018-10-15vnet: create L2 feature arc infrastructureAndrew Yourtchenko6-2/+727
This commit adds two new nodes in the L2 datapath in input and output direction respectively. These nodes fork the traffic into three feature arcs: ip4, ip6 and nonip, which later join to continue the usual L2 processing. The vnet_l2_feature_enable_disable() function with the same signature as vnet_feature_enable_disable() takes care of enabling the L2 datapath feature bits as needed, when the features are enabled/disabled. Thus, L2 features may use the similar plumbing as the L3 features enjoy. Change-Id: I76877b3a92d794c492bff1622bb26acba05705b2 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-07-15VPP-1341: fix loopback interface graph arcsDave Barach1-15/+0
Remove broken special case from l2_input.c:set_int_l2_mode(), which turns out to confuse the graph dispatch engine. The loopback TX function needs to push packets to either ethernet-input or to l2-input, based on bridge / BVI configuration. Rather than overloading a single graph arc - and making vain attempts to reconfigure it - create both arcs and use the correct one. Rewrote the loopback tx function as an idosyncratic multi-arch quad/single loop fn. Change-Id: I15b56ce641d90a11e7b3c7d23859f40e168dd7b2 Signed-off-by: Dave Barach <dave@barachs.net>

Improve "show l2fib" CLI to allow display of all entries, learned entries only, or added ovia CLI/API entries only. For added entry, show "no" under the age column to indicate entry does not age.

2018-05-11Periodic scan and probe of IP neighbors to maintain neighbor poolsJohn Lo1-5/+2
Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.

2018-04-13bond: ping fails between l2 BD [VPP-1238]Steven1-0/+7
In dpdk based bonding, when the bond interface is configured for l2, it automatically sets the bond interface to promiscuous mode and sets rx redirect to ethernet-input. This allows traffic to be bridged to non compute node facing interface when it is received from the compute node interface. For native vpp bonding, we need to do similar things. When the bond interface is configured for l2, we set the slave interfaces to promiscuous mode and set rx redirect to ethernet-input because dpdk does not know anything about the bond interface. Likewise, when a new interface is enslaved, we also need to do the same thing if the bond interface has already been configured for l2.
