2017-02-22Repair SNAT's IPFIX and IF-add-del test functions.Jon Loeliger1-2/+2
Inspection shows that the names of two functions: api_snat_ipfix_enable_disable() api_snat_add_del_interface_addr() don't match their bodies and have been swapped. Make the world right again by swapping them to match. Change-Id: Ieefd7f0fdbf52794e8649b0cbbcf6e1403c1b90a Signed-off-by: Jon Loeliger <jdl@netgate.com>

2017-02-03Plugin infrastructure improvementsDamjan Marion2-22/+6
This patch replaces requirement for vlib_plugin_register function in the plugin so file and introduces new macro: VLIB_PLUGIN_REGISTER () = { .version = "version string", .version_required = "requred version", .default_disabled = 1, .early_init = "early_init_function_name", }; Plugin will nor be loaded if .default_disabled is set to 1 unless explicitely enabled in startup.conf. If .verstion_required is set, plugin will not be loaded if there is version mismatch between plugin and vpp. This can be bypassed by setting "skip-version-check" for specific plugin. If .early-init string is present, plugin loader will try to resolve this specific symbol in the plugin namespace and make a function call. Following startup.conf configuration is added: plugins { path /path/to/plugin/directory plugin ila_plugin.so { enable skip-version-check } plugin acl_plugin.so { disable } } Change-Id: I706c691dd34d94ffe9e02b59831af8859a95f061 Signed-off-by: Damjan Marion <damarion@cisco.com>

Ports are allocated per protocol (UDP, TCP, ICMP) 1:1 NAT with port is configured for specific protocol Change-Id: I37ae5eed3715b223d0620d4fdaed7a482bb7a834 Signed-off-by: Matus Fabian <matfabia@cisco.com>
2017-02-02Remove unnecessary block structure around CONTROL_PING messages.Jon Loeliger1-25/+25
Now that the M() and S() macros accept a message parameter, there is no longer a need to introduce a new block structure around the CONTROL_PING messages just to have a new unbound "mp" variable. Instead, just use one named "mp_ping" directly. Change-Id: I6b283562bb6eec25806e3d35c35b977680ecd1dd Signed-off-by: Jon Loeliger <jdl@netgate.com>
2017-02-02Refactor fragile msg macro W and W2 to not burry return control flow.Jon Loeliger1-38/+36
Instead, have them accept and assign a return paramter leaving the return control flow up to the caller. Clean up otherwise misleading returns present even after "NOT REACHED" comments. Change-Id: I0861921f73ab65d55b95eabd27514f0129152723 Signed-off-by: Jon Loeliger <jdl@netgate.com>
2017-02-02Localize the timeout variable within the W message macro.Jon Loeliger1-12/+0
Rather than rely on an unbound variable, explicitly introduce the timeout variable within the 'do { ... } while (0)' construct as a block-local variable. Change-Id: I6e78635290f9b5ab3f56b7f116c5fa762c88c9e9 Signed-off-by: Jon Loeliger <jdl@netgate.com>
2017-02-02Convert message macro S to accept a message pointer parameter;Jon Loeliger1-17/+24
Rather than blindly assume an unbound, fixed message parameter explicilty pass it as a paramter to the S() macro. Change-Id: Ieea1f1815cadd2eec7d9240408d69acdc3caa49a Signed-off-by: Jon Loeliger <jdl@netgate.com>
2017-02-02Ensure all M() and M2() second parameters are the message pointer.Jon Loeliger1-17/+17
Rather than maintain (?) an unused second parameter, t, and pull an unbound message pointer, mp, out of context, explicitly list the message pointer as the second parameter. Change-Id: I92143efda6211cdf6b935470f8c71579742a6b64 Signed-off-by: Jon Loeliger <jdl@netgate.com>
2017-02-02SNAT: changed source for outbound address FIB entry (VPP-613)Matus Fabian1-21/+11

2017-01-31SNAT: Add outbound addresses to FIB (VPP-613)Matus Fabian1-1/+110
Add the external NAT address to the FIB as receive entries. This ensures that VPP will reply to ARP for these addresses and we don't need to enable proxy ARP on the outside interface. Change-Id: I1db153373c43fec4808845449a17085509ca588c Signed-off-by: Matus Fabian <matfabia@cisco.com>
