2019-05-15Remove unused function nat44_ha_resync() and error IN_PROGRESS.Jon Loeliger1-38/+0
The unused function nat44_ha_resync() was the only function that used the error message VNET_API_ERROR_IN_PROGRESS. The error was the only error code that was positive, and didn't really play well with the other error codes.

2019-04-26nat: fix ED mode unknown proto session managementMatthew Smith3-8/+24
In endpoint dependent mode, when a session at the head of a user LRU is reused, if the IP protocol for that session was unknown (any other than tcp, udp, or icmp), the attempt to delete the session mapping from the in2out bihash was not using the same key that was used when the mapping was added. This would cause the deletion of the mapping to fail. If packets arrive later which match the original session, the search for the session key would succeed when it should have failed and the session, which is now associated with a different pair of endpoints, may end up being updated when it should not be. Update the key generation when reallocating an existing session to do the right thing if the session is for an unknown protocol. Also update format_nat_session() for unknown protocols so that 'vppctl show nat44 session detail' will display the protocol correctly. In endpoint dependent mode, the IP protocol is stored in the port field on a session if the protocol is unknown. The value is stored in host byte order, but the format function was swapping the bytes before writing the protocol.

2019-04-26nat: prevent creation when-resolved static mappings on errorsAlexander Chernavin1-1/+1
When you create two identical NAT44 static mappings using interface name as external address and only local or ext port is different, VALUE_EXIST will be raised but when-resolved static mapping will remain. vpp# nat44 add static mapping tcp local 10.128.0.129 443 external GigabitEthernet0/8/0 8443 vpp# nat44 add static mapping tcp local 10.128.0.129 80 external GigabitEthernet0/8/0 8443 nat44 add static mapping: Mapping already exist. vpp# show nat44 static mappings NAT44 static mappings: tcp local 10.128.0.129:443 external 2.2.2.2:8443 vrf 0 tcp local 10.128.0.129:443 external GigabitEthernet0/8/0:8443 vrf -1 tcp local 10.128.0.129:80 external GigabitEthernet0/8/0:8443 vrf -1 With this commit, when-resolved static mapping is not created if the translation only differs in local or ext port.

2019-04-10API: Fix shared memory only action handlers.Ole Troan1-11/+11
Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport. A couple (bond / vhost) also tried to send a sw_interface_event directly, but did not send the message to all that had registred interest. That scheme never worked correctly. Refactored and improved the interface event code. Change-Id: Idb90edfd8703c6ae593b36b4eeb4d3ed7da5c808 Signed-off-by: Ole Troan <ot@cisco.com>
2019-04-09nat: initialize fq_in2out_output_indexMatthew Smith1-0/+1
When using the output feature ('postrouting') outbound translation, no packets are passed when using worker threads. The frame queue for in2out packets to be handed off between threads is never allocated. This is because that allocation only happens if the value of fq_in2out_output_index == ~0, but fq_in2out_output_index is never initialized prior to checking that. Initialize fq_in2out_output_index to ~0 so a frame queue will be allocated when there are worker threads.
