2021-02-12policer: remove SSE2 prefixBrian Russell8-483/+424
The policer code uses a naming convention of prefixing a lot of its definitions with "SSE2" when in fact there is nothing SSE2 specific about them. This is confusing so remove the prefix. Unfortunately it has to stay in the API definitions for backward compatibility.

2021-01-28policer: add policer handoffBrian Russell2-0/+81
Add thread handoff for packets being policed. Note that the handoff currently requires the policer index to be passed in. This is suitable for use in the ip[46] punt paths where each policer node will only ever use a single policer. For the more general case, this will be expanded in future to use a policer index stored in packet metadata.

2021-01-28policer: add thread index to policerBrian Russell2-3/+8
Add a thread index field to the policer structure. The policer is not thread safe. The thread index will be used to tie it to one worker thread and other workers can use thread handoff.

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>
2018-01-11api: remove transport specific code from handlersFlorin Coras1-7/+7
This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that.

Done for the following apis: Plugins - acl - gtpu - memif - nat - pppoe VNET - bfd - bier - tapv2 - vhost user - dhcp - flow - geneve - ip - punt - ipsec/ipsec-gre - l2 - l2tp - lisp-cp/one-cp - lisp-gpe - map - mpls - policer - session - span - udp - tap - vxlan/vxlan-gpe - interface VPP - api/api.c OAM - oam_api.c Stats - stats.c Change-Id: I0e33ecefb2bdab0295698c0add948068a5a83345 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace2-1/+3
- 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 results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-10-20null-terminate some formatted stringGabriel Ganne1-0/+2
Any u8* variable created by format() is NOT null-terminated. Add the null terminating byte with vec_terminate_c_string(). If that variable is used by (at least) hash_get_mem(), then it needs to be null-terminated, as it will go through string_key_sum() which makes a call to strlen.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall2-8/+24
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.
