2018-04-17ACL based forwardingAndrew Yourtchenko1-0/+20
A poor man's flow switching or policy based rounting. An ACL is used to match packets and is associated with a [set of] forwarding paths that determine how to forward matched packets - collectively this association is a 'policy'. Policies are then 'attached', in a priority order, to an interface when thaey are encountered as an input feature. If a packet matches no policies it is forwarded normally in the IP FIB. This commit is used to test the "ACL-as-a-service" functionality, which currently compiles, and the existing traffic ACL tests pass in both hash and linear modes.

2018-03-23acl-plugin: make test: shuffle applied ACLs as part of the testsAndrew Yourtchenko1-0/+6
During the testing of 94f9a6de3f706243d138e05b63fef1d5c8174f6c I realized there was no test coverage for the cases where the ACLs are added then modified while having beein applied. This change adds some simple shuffling to l2l3 ACL test set, whereby after each of the ACLs being applied, a few extra ACLs are applied at the front and the back of the list, and are changed several times, the base for the changes being the set of all the ACEs that are being applied previously. After these few shuffles, the routine restores the applied ACLs and proceeds to the test as usual.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+75
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.

2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-4/+10
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.

2018-02-08acl-plugin: add whitelisted ethertype mode (VPP-1163)Andrew Yourtchenko1-0/+10
Currently, ACL plugin largely does not care about the ethertypes other than 0x0800 (IPv4) and 0x86dd (IPv6), the only exception being 0x0806 (ARP), which is dealt with by the MACIP ACLs. The other ethertypes in L2 mode are just let through. This adds a new API message acl_interface_set_etype_whitelist, which allows to flip the mode of a given interface into "ethertype whitelist mode": the caller of this message must supply the two lists (inbound and outbound) of the ethertypes that are to be permitted, the rest of the ethertypes are dropped. The whitelisting for a given interface and direction takes effect only when a policy ACL is also applied. This operates on the same classifier node as the one used for dispatching the policy ACL, thus, if one wishes for most of the reasonable IPv4 deployments to continue to operate within the whitelist mode, they must permit ARP ethertype (0x0806) The empty list for a given direction resets the processing to allow the unknown ethertypes. So, if one wants to just permit the IPv4 and IPv6 and nothing else, one can add their ethertypes to the whitelist. Add the "show acl-plugin interface" corresponding outputs about the whitelists, vat command, and unittests.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-0/+23
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.

2018-01-23For DHCP client configuration control the setting of the broadcast flag in theNeale Ranns1-0/+2
DISCOVER message sent. According to RFC2131: In the case of a client using DHCP for initial configuration (before the client's TCP/IP software has been completely configured), DHCP requires creative use of the client's TCP/IP software and liberal interpretation of RFC 1122. The TCP/IP software SHOULD accept and forward to the IP layer any IP packets delivered to the client's hardware address before the IP address is configured; DHCP servers and BOOTP relay agents may not be able to deliver DHCP messages to clients that cannot accept hardware unicast datagrams before the TCP/IP software is configured. To work around some clients that cannot accept IP unicast datagrams before the TCP/IP software is configured as discussed in the previous paragraph, DHCP uses the 'flags' field [21]. The leftmost bit is defined as the BROADCAST (B) flag. The semantics of this flag are discussed in section 4.1 of this document. The remaining bits of the flags field are reserved for future use. They MUST be set to zero by clients and ignored by servers and relay agents. Figure 2 gives the format of the 'flags' field. this changes means VPP conforms to the: "SHOULD accept and forward to the IP layer any IP packets delivered to the client's hardware address before the IP address is configured" with the caveat that VPP allows DHCP packets destined to the stanard client DHCP port to be delivered. With this enhancement the control-plane is now able to choose the setting of the broadcast flag. Change-Id: Ia4eb2c9bb1e30c29f9192facc645e9533641955a Signed-off-by: Neale Ranns <nranns@cisco.com>
