2018-05-17Fix failure during enable/disable of featuresMatthew Smith2-5/+5
vnet_feature_enable_disable_with_index() checks the return status of vnet_config_{add,del}_feature(). If the config string heap index returned is the same index that was in use prior to the add/delete, it is concluded that a failure occurred and processing of the feature stops. Sometimes the config index that is returned can legitimately be the same index that was in used before the add/delete. The old list of features can have its heap entry deallocated before a new entry for the new list is allocated. The heap entry for the new list can be the entry that was deallocated while deleting the old one. Make vnet_config_{add,del}_feature() return ~0 on failure. Look for that return value as an indication that an error occurred in vnet_enable_disable_feature_by_index().

Instead of repeatedly cutting, pasting, and hacking to create a new callback, use vnet_flow_rewrite_generic_callback(). Add three arguments to the flow rewrite callback: (in) pointer to an array of report elements, (in) length of array, (out) pointer to the stream index Change existing code prototypes.

2018-05-11Periodic scan and probe of IP neighbors to maintain neighbor poolsJohn Lo9-14/+533
Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.

2018-05-10Change the way IP header pointer is calculated in esp_decrypt nodesSzymon Sliwa2-3/+11
The pointer to IP header was derived from l3_hdr_offset, which would be ok, if l3_hdr_offset was valid. But it does not have to be, so it was a bad solution. Now the previous nodes mark whether it is a IPv6 or IPv4 packet tyle, and in esp_decrypt we count get ip header pointer by substracting the size of the ip header from the pointer to esp header (which lies in front of the ip header).

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>

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.
