2018-02-12Fix DHCP client crash with worker threadsMatthew Smith1-1/+1
Crash occurring With a worker thread configured and dhcp client active on an interface. When a DHCP reply packet is received, call to ethernet_get_main() from dhcp_proxy_to_client_input() was causing a crash. Replaced with a call to vnet_get_ethernet_main(). Once that was resolved, calling dhcp_client_acquire_address() from a worker thread also caused a crash. Changed so the main thread will do the address/route configuration.

2017-11-16Add Support of DHCP VSS Type 0 where VPN-ID is ASCIIJohn Lo1-89/+72
Enhence support of DHCP VSS (Virtual Subnet Selection) to include VSS type 0 where VSS info is a NVT (Network Virtual Terminal) ASCII VPN ID where the ASCII string MUST NOT be terminated with a zero byte. Existing code already support VSS type 1, where VSS information is a RFC 2685 VPN-ID of 7 bytes with 3 bytes OUI and 4 bytes VPN index, and VSS type 255 indicating global VPN.

2017-09-11FIB table add/delete APINeale Ranns1-4/+5
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-1/+1
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-03-07DHCP Multiple Servers (VPP-602, VPP-605)Neale Ranns1-33/+118
Multiple DHCP (4 and/or 6) servers can be added and removed through multiple calls to the 'set dhcp server' API. All 4/6/ discover/solicit messages will then be replicated to all servers in the list. The expectation is that the servers/system is configured in such a way that this is viable. If VSS information is providied for the clinet VRF which also has multiple servers configured, then the same VSS information is sent to each server. Likewise the source address of packets sent to from VPP to each server is the same. Change-Id: I3287cb084c84b3f612b78bc69cfcb5b9c1f8934d Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-02-16Consolidate DHCP v4 and V6 implementation. No functional change intendedNeale Ranns1-0/+983
The DHCP proxy and VSS information maintained by VPP is the same for v4 and v6, so we can manage this state using the same code. Packet handling is cleary different, so this is kept separate. Change-Id: I10f10cc1f7f19debcd4c4b099c6de64e56bb0c69 Signed-off-by: Neale Ranns <nranns@cisco.com>
