2018-05-10DHCP4 client process replies when renewing leaseMatthew Smith1-16/+24
When a DHCP client is in the bound state, it wakes up halfway through it's lease (by default) to try and renew the lease. The ip4-dhcp-client-detect is not enabled as a feature at this point, so replies sent from the DHCP server do not get applied to the lease. Eventually the lease expires, the address is removed from the interface, a new discovery is performed and the same address is added back to the interface. Before sending a request to renew in the bound state, enable the feature to process the reply. Change-Id: I95332ee0596f47df6f3c8bf8e3f0698dde9a1fc5 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2018-04-25span: crash in span_mirror [VPP-1254]Steven1-2/+7
It is possible for span-input to get call with sw_if_index which is greater than sm->interfaces and crashes in span_mirror () in the following line span_interface_t *si0 = vec_elt_at_index (sm->interfaces, sw_if_index0); For example, span-input mirrors a main interface as source, it may actually get call for traffic coming in from the subinterface and crashes. The fix is simply to check if sw_if_index >= vec_len (sm->interfaces) and punt if it is.

2018-04-24lacp: deleting the bond subinterface may cause lacp to lose the partner ↵Steven3-23/+2
[VPP-1251] Problem: When the bond subinterface is removed, it was observed that we lost the lacp partner. Show hardware shows rx counter goes up, but show interface does not for the slave interfaces. Cause: We reset the interface promiscuous mode when the bond subinterface is deleted. This causes dpdk not to accept any packet. Leave the interface in promiscuous mode fixes the problem. Other fixes: There are few places we use hw_if_index as if they are sw_if_index. But they don't necessarily have the same value. As soon as a subinterface is created, they start to diverge. The fix is to use the correct API for the hw_if_index and sw_if_index.

Some scenarios not involving ip[4,6]-input paths might benefit from IP header QOS fields recorded and applied. An example: L2 (overlay) traffic being encapsulated by VPP in VXLAN and transmitted on another (underlay) interface might want the QOS information carried over in the outer IP header.

2018-04-19Allow an IPsec tunnel interface to be renumberedMatthew Smith5-29/+42
When creating an IPsec tunnel interface, allow a numeric identifier to be set for use in the interface's name in place of the dev instance. Default to using the dev instance if no value is explicitly set. When an IPsec tunnel is deleted, the interface is deleted now instead of being kept in a pool of available hw interfaces. Otherwise there was the possibility of conflicting tx node names between deleted tunnels and newly created ones.
