2018-01-24Improve tunnel interface creation performanceJohn Lo8-90/+86
Modify interface creation to allow creation of tunnel interfaces without dedicated per tunnel output and tx nodes which are not used for most tunnel types. Also changed interface-output node function vnet_per_buffer_interface_output() so it does not rely on hw_if_index as the next node index which is not flexible nor efficient for large scale tunnel interfaces. The improvenemts are done for VXLAN, VXLAN-GPE, GENEVE and GTPU tunnels. GRE tunnel is still using per tunnel output nodes which will be changed in a separate patch with other GRE enhencements.

2018-01-23For DHCP client configuration control the setting of the broadcast flag in theNeale Ranns10-107/+426
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>

2018-01-16acl-plugin: multicore: use pool_init_fixed for per-worker preallocated poolsAndrew Yourtchenko1-1/+7
One worker thread may be processing the packets for session owned by another worker thread. During session access the validity of the pool index is checked - however, the free bitmap pointer might change just at that moment, potentially resulting in a crash. Thus, use the pool_init_fixed() when initializing the per-worker pools, so that the free bitmaps are as well staying in their place.

2018-01-16tapv2: deleting tap interface may leak buffers (VPP-1124)Steven4-11/+34
Buffers may be allocated for indirect descriptors by tx thread and they are freed when tx thread is invoked in the next invocation. This is to allow the recipient (kernel) to have a chance to process them. But if the tap interface is deleted, the tx thread may not yet be called to clean up the indirect descriptors' buffers. In that case, we need to remove them without waiting for the tx thread to be called. Failure to do so may cause buffers leak when the tap interface is deleted. For the RX ring, leakage also exists for vring->buffers when the interface is removed.
