2017-03-03Implement a loopback instance allocation scheme.Jon Loeliger2-12/+117
To support creating loopback interfaces with a specific instance number, a new CREATE_LOOPBACK_INSTANCE API call with flag is_specified and value user_instance is introduced. Presumably the existing CREATE_LOOPBACK API message will be obsoleted and revmoved. The VAT cli commands can now mention and format the new field as 'instance %d' data. If no instance number is named, the old call CREATE_LOOPBACK is used to maintain backward compatibility. However, if the instance is named, the new CREATE_LOOPBACK_INSTANCE message will be used. Both the dynamically allocated and user-requested instance number are tracked in a bitvector. If is_specified is 0, the next free instance will be used.. A request for a specific instance number will be granted if it is available. On error, the value ~0 is returned.

2017-03-03VPP-651: Ensure sw_if_index to node mapping for L2 output path is only done ↵Andrew Yourtchenko3-3/+17
via l2output_main.next_nodes Before this commit, several output features that happen to be the last in the list of features to be executed, send the packets directly to <interfaceName>-output. To do this, they use l2_output_dispatch, which builds a list of sw_if_index to next index mappings. When interfaces are deleted and the new interfaces are created, these mappings become stale, and cause the packets being sent to wrong interface output nodes. This patch (thanks John Lo for the brilliant idea!) adds a feature node "output", whose sole purpose is dispatching the packets to the correct interface output nodes. To do that, it uses the l2output_main.next_nodes, which is already taken care of for the case of the sw_if_index reuse, so this makes the dependent features all work correctly. Since this changes the packet path, for the features that were always the last ones it has triggered a side problem of the output feat_next_node_index not being properly initalized. These two users are l2-output-classify node and the output nodes belonging to the acl-plugin. For the first one the less invasive fix is just to initialize that field. For the acl-plugin nodes, rewrite the affected part of the code to use feat_bitmap_get_next_node_index since this is essentially what the conditional in l2_output_dispatch does, and fix the compiler warnings generated. This fix was first made in stable/1701 under commit e7dcee4027854b0ad076101471afdfff67eb9011.

2017-03-02Clean up binary api message handler registration issuesDave Barach7-164/+2
Removed a fair number of "BUG" message handlers, due to conflicts with actual message handlers in api_format.c. Vpp itself had no business receiving certain messages, up to the point where we started building in relevant code from vpp_api_test. Eliminated all but one duplicate registration complaint. That one needs attention from the vxlan team since the duplicated handlers have diverged. Change-Id: Iafce5429d2f906270643b4ea5f0130e20beb4d1d Signed-off-by: Dave Barach <dave@barachs.net>

2017-02-28Clear L2 output config on interface mode change to L3 (VPP-651)John Lo1-4/+11
With VPP-651, the L2 output config with L2-tag rewrite was not cleared when a sub-interface is deleted. Subsequently, when the same sw_if_index was reused for another interface, the L2 output config with L2-tag rewrite remained on the new interface. On deleting a (sub-)interface which is in L2 mode, it will be changed to L3 mode first to clear any L2 config. The L2 to L3 mode change path did address L2 input config cleanup. It is now fixed to also clear L2 output config. Change-Id: I3352a89d92e1b27340a5adcf75bbaa01a5050c29 Signed-off-by: John Lo <loj@cisco.com>

2017-02-24VPP-279: Document changes for vnet/vnet/devicesBilly McFall2-100/+617
Add doxygen documentation for dpdk CLI commands. Outside of adding documentation to the CLI Commands, modified the CLI code as follows: * The "set dpdk interface placement" command allows the user to move interface/queues to a different thread. But there is only a subset of threads that are valid. Updated the "show dpdk interface placement" command to display all valid threads, even if all interface/queues have been moved off. Updated the "show dpdk interface hqos placement" the same way. * There is a command to modify the Subport attributes, but no way to display the changes. Added a "Subport" section to the "show dpdk interface hqos" command. * Reworked the "set dpdk interface hqos subport" command. - The current implementation had a local rte_sched_subport_params structure and initialized it to default values, then overwrote with what was input. The side effect of this is that if all the current data is non-default, and a new command is entered with just one attribute, all the remaining attrbutes are getting set back to default under the cover. Very confusing for the user. Updated the code to read the current value and overwrite what has changed. - DPDK does not have a read subport data, so no way query the current applied values. The set command was not updating the local copy that is created at init. Modified the code to store the updated values if the DPDK apply function was successful. - Several functions repeated the same code to get a pointer to the local HQoS data. Added a utility function.get_hqos(..), to perform this action. Did not port other code to use new function. * The "set dpdk interface hqos pktfield" allows the user to set the packet fields required for classifiying the incoming packet. The classification is across three fields (subport, pipe, tc). The command was using 0,1,2 to represent these three fields, but had no explanation regarding these magic numbers. Updated the command to take the three tokens (subport, pipe, tc) for more clarity. For legacy sake, still allow 0,1,2 to be entered. Also updated the "show dpdk interface hqos" command to show these tokens. * The "set dpdk interface hqos tctbl" maps an interface and value 0-63 to a traffic class and queue. The "show dpdk interface hqos" command showed the internal DPDK magic number for traffic class and queue. Updated the show command to display what was input instead of the magic number. * The "show dpdk hqos queue" command always returns zeros by default because RTE_SCHED_COLLECT_STATS is not defined in DPDK. Took me a while to figure out why I wasn't getting values returned. So returned an error message if RTE_SCHED_COLLECT_STATS is not defined instead of zeros.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall27-429/+1163
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.
