2018-04-16Implement ip_probe_neighbor APIJohn Lo1-1/+56
Add API support similar to VPP CLI "ip probe-neighbor" except API call is asynch and will not wait, as the CLI does, for address resolution of probed neighbor. The API client can use the APIs want_ip4_arp_events or want_ip6_nd_events to get notified of the desired address resolution event.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-1/+476
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.

2018-03-02tapv2: CLI and binary API fixesSteven1-7/+7
1. When interface create encouners an error (see test below), the same id cannot be used again. This is due to hash_set is called too early in the function. After the hash entry is set, there are different errors may cause the interface create to be aborted. But we didn't remove the hash entry when error is encountered. The fix is to move the hash_set call near the end which has no more "goto error" DBGvpp# create tap id 1 rx-ring-size 1021 tx-ring-size 1021 create tap id 1 rx-ring-size 1021 tx-ring-size 1021 create tap: ring size must be power of 2 DBGvpp# create tap id 1 rx-ring-size 1024 tx-ring-size 1024 create tap id 1 rx-ring-size 1024 tx-ring-size 1024 create tap: interface already exists DBGvpp# 2. multiple issues exist with api_format.c with the below command binary-api tap_create_v2 id 4 hw-addr 90:e2:ba:76:cf:2f rx-ring-size 1024 tx-ring-size 1024 - hw_addr is not taken due to the test for random mac is inverted - id is an integer, not a string - integer values were not converted to network format Change-Id: I5a669d702a80ad158517df46f0ab089e4d0d692e Signed-off-by: Steven <sluong@cisco.com>
2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-11/+23
Change GRE tunnel to use the interface type where the same encap node is used as output node for all GRE tunnels, instead of having dedicated output and tx node for each tunnel. This allows for more efficient tunnel creation and deletion at scale tested at 1000's of GRE tunnels. Add support for ERSPAN encap as another tunnel type, in addition to the existing L3 and TEB types. The GRE ERSPAN encap supported is type 2 thus GRE encap need to include sequence number and GRE- ERSPAN tunnel can be created with user secified ERSPAN session ID. The GRE tunnel lookup hash key is updated to inclue tunnel type and session ID, in addition to SIP/DIP and FIB index. Thus, GRE-ERSPAN tunnel can be created, with the appropriate session ID, to be used as output interface for SPAN config to send mirrored packets. Change interface naming so that all GRE tunnels, irrespective of tunnel type, uses "greN" where N is the instance number. Removed interface reuse on tunnel creation and deletion to enable unfied tunnel interface name. Add support of user specified instance on GRE tunnel creation. Thus, N in the "greN" interface name can optionally be specified by user via CLI/API. Optimize GRE tunnel encap DPO stacking to bypass load-balance DPO node since packet output on GRE tunnel always belong to the same flow after 5-tupple hash.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-2/+60
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

Since we no longer create pg interfaces we're not planning to use, the filter catalog does more harm than good. Every new interface name prefix would have had to be added to the list, and folks wouldn't likely know they should do that...

If rules overlap, ordering is established by tuple longest match with the following descending priority: remote ip, local ip, remote port, local port. At this time, the only match action supported is to forward packets to the application identified by the action.

2017-10-10session: add support for application namespacingFlorin Coras1-3/+55
Applications are now provided the option to select the namespace they are to be attached to and the scope of their attachement. Application namespaces are meant to: 1) constrain the scope of communication through the network by association with source interfaces and/or fib tables that provide the source ips to be used and limit the scope of routing 2) provide a namespace local scope to session layer communication, as opposed to the global scope provided by 1). That is, sessions can be established without assistance from transport and network layers. Albeit, zero/local-host ip addresses must still be provided in session establishment messages due to existing application idiosyncrasies. This mode of communication uses shared-memory fifos (cut-through sessions) exclusively. If applications request no namespace, they are assigned to the default one, which at its turn uses the default fib. Applications can request access to both local and global scopes for a namespace. If no scope is specified, session layer defaults to the global one. When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY) binds are converted to binds to the requested interface.
