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.

2017-04-06Use thread local storage for thread indexDamjan Marion16-116/+94
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.

2017-04-01Clean up event log merge codeDave Barach1-1/+1
Fix a decade-old ridiculous qsort function bug. Managed to subtract floating-point numbers as if they were integers, leading to manufactured time-paradoxes. That completely confuses g2, leading to the summary disappearance of entire tracks' worth of data at high zoom levels. Add a manual alignment tweak parameter to elog_merge, users can dial-out time paradoxes caused by NTP-grade clock synchronization. The event-logger has a precision of O(100ns), whereas NTP synchronization is O(1ms). Change-Id: I69dedabaa314f69f9df74ec9ee66e21e6c87f703 Signed-off-by: Dave Barach <dave@barachs.net>

2017-03-22vhost: support interrupt modeSteven1-5/+8
vhost currently supports only polling mode. This patch is to add interrupt mode. When the interface is configured for interrupt mode, our input node does not get called unless there is a packet in the vring. If a particular CPU has one interface configured for polling mode and another in interrupt, the input node is set to polling for that CPU. This diffs also includes two crashes in vlib's dispatch_node. One is included in https://gerrit.fd.io/r/#/c/5516. The other crash is in the ASSERT. The ASSERT can become true when the caller of dispatch_node is in a loop. The first call converted the node to polling. The second call thereafter will hit the ASSERT.

2017-03-17vlib: fix potential crash in dispatch_node ELOG_DATA callSteven1-2/+11
dispatch_node may be invoked from vlib main or worker threads. The call to ELOG_DATA in dispatch_node passes the parameter &vm->elog_main. It works fine when dispatch_node is invoked from the main thread. It does bad thing when it is invoked from the worker thread. While we are at it, make two additional enhancements to the same area. 1. Use ELOG_TRACK_DATA instead of ELOG_DATA to enhance g2 viewer presentation. 2. Since ELOG_DATA is in the data path, it could get very chatty. Make the call to ELOG_TRACK_DATA conditional compile.

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>

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall3-34/+80
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>
