2018-04-25Fix some build warnings about "Old Style VLA"Juraj Sloboda1-2/+2

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.

2018-04-18Fix the ip header offset counting in vnet/ipsecSzymon Sliwa1-5/+4

2018-04-10Make IPsec tunnel intf work with IPv4 output featuresMatthew Smith1-0/+7
With no IPv4 output features on an IPsec tunnel inferface, when packets are forwarded to that interface, they reach the ipsec-if-output node via the output_node_index on the hw interface and they are handled correctly. When an IPv4 output feature (e.g. output ACL, outbound NAT) is enabled on an IPsec tunnel interface, outbound IPsec stops working for that interface. The last node in the ip4-output feature arc is interface-output. From there a packet is sent to ipsec<N>-output, and then ipsec<N>-tx. The tx function for an IPsec tunnel interface that is called by ipsec<N>-tx is a dummy that doesn't do anything except write a warning message. Enable a feature on the interface-output feature arc for an IPsec tunnel interface so the ipsec-if-output node is reached from the interface-output node.

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>

Make it easier to integrate with external IKE daemon. IPsec interfaces can have one or both SAs replaced after creation. This allows for the possibility of setting a new child SA on an interface when rekeying occurs. It also allows for the possibility of creating an interface ahead of time and updating the SA when parameters that are negotiated during IKE exchange become known.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace6-3/+8
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included.

This patch reworks the DPDK ipsec implementation including the cryptodev management as well as replacing new cli commands for better usability. For the data path: - The dpdk-esp-encrypt-post node is not necessary anymore. - IPv4 packets in the decrypt path are sent to ip4-input-no-checksum instead of ip4-input. The DPDK cryptodev cli commands are replaced by the following new commands: - show dpdk crypto devices - show dpdk crypto placement [verbose] - set dpdk crypto placement (<device> <thread> | auto) - clear dpdk crypto placement <device> [<thread>] - show dpdk crypto pools Change-Id: I47324517ede82d3e6e0e9f9c71c1a3433714b27b Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>

Add a handler for incoming messages with the new request type. Add an API response message type containing the data for an IPsec SA. Add VAT support for new message type.

2017-04-06Use thread local storage for thread indexDamjan Marion6-51/+61
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-55/+122
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.
