2017-05-23Add TAB-based auto-completion to the CLIYoann Desmouceaux1-0/+153
Hitting tab: - in the middle of a uniquely defined subcommand will expand the subcommand - in the middle of a non-uniquely defined (or empty) subcommand will display all possible subcommands, and possibly expand to the lowest common prefix Change-Id: Ib858eefdb0353cd2c3aad472799d15cd537455a0 Signed-off-by: Yoann Desmouceaux <ydesmouc@cisco.com>

2017-04-26Exit if plugin load attempt failDamjan Marion1-6/+2
This happens mainly if plugin contains unresolved symbol. Such situation typically leads on crash a bit later so it is better to exit immediatelly and display meaningful error message. Change-Id: I4abd9a9089a4863400bf609e8d3fd7cebab92913 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-04-11Fix typo in minimal epoll polling timePierre Pfister1-1/+1
epoll was supposed to not sleep when timeout is less than 1ms, but a typo made it not sleep any time the requested timeout is lower than 1000 seconds (in practice, never...). This patch replaces "1e3" with "1e-3", which represents 1ms. Change-Id: I731851b27a6bf6ab8e41586e017e94b962b09bf3 Signed-off-by: Pierre Pfister <ppfister@cisco.com> (cherry picked from commit ec06222ae189fe8d84b63410130fff04bf446573)
2017-04-06Use thread local storage for thread indexDamjan Marion3-28/+24
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.

2017-03-02Clean up binary api message handler registration issuesDave Barach1-7/+24
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>
2017-02-26Load plugins in alphabetical orderDave Barach1-9/+55
API traces contain absolute message numbers. Loading plugins in directory (vs. alphabetical) order makes trace replay fragile. Change-Id: I46b3a3b6a9843a383d42269fca0cf5a789486eaf Signed-off-by: Dave Barach <dave@barachs.net>
2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-6/+16
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.

2017-02-03Plugin infrastructure improvementsDamjan Marion3-60/+318
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>
