2020-11-25vlib: add elog events for vlib log entriesDave Barach1-0/+5
Pretty interesting to see how long plugins take to load. Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: If496eb73b2e1fd9dd714142cd5195fa7ccd93ebd
2020-10-21vlib: print logs to stderr if interactive or nosyslog setDamjan Marion1-0/+10
If VPP is started in interactive mode, instead of sending logs to syslog server we print them directly to stderr. Output is colorized, but that can be turned off with unix { nocolor } Type: improvement Change-Id: I9a0f0803e4cba2849a6efa0b6a86b9614ed33ced Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-10-09vlib: save signal handler data to global vblsDave Barach1-4/+4
Turns out that clang is a bit too enthusiastic about mapping static variables to registers, which makes it hard to extract (especially) the faulting VA from an optimized core file. Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I836e5d9695aeb4c5ee4a27f9565acf08ee4eaac0

Heap may use different page sizes so we will not be able to create stack protection page. Type: improvement Change-Id: Ibb35c9f0a151c464ee0167d17f2bd773ef6f530b Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-09-03vlib: exit 0 (nocore) on SIGHUPChristian Hopps1-2/+2
Scenarios where SIGHUP is sent would include the user closing an xterm while in interactive/nodaemon mode, or similarly when running vpp in the same mode during testing (e.g., using ssh to run VPP on a DUT). VPP should exit in these cases; however, generating a core is unwanted. Type: fix Signed-off-by: Christian Hopps <chopps@labn.net> Change-Id: Ibccfe5e676547e913c8a205ff16ab56d9abb1c82

2020-05-02vlib: add nosyslog unix optionRuslan Babayev1-3/+10
The "nosyslog" option disables syslog just like the "interactive" mode but can be used together with "nodaemon". This is useful for when VPP is running under a process supervisor like runit or daemontools that pipe the stdout/stderr to a dedicated logger service.

2020-03-21vlib: leave SIGPROF signal with its default handlerJieqiang Wang1-0/+1
When profiling VPP with MAP (a software profile suite on Arm CPUs, see details in https://www.arm.com/products/development-tools/server-and-hpc/forge/map) on Arm servers, VPP will receive SIGPROF signal because MAP uses SIGPROF signal to drive its sampler to do profiling on VPP. However, the default action of SIGPROF signal handler in VPP such as unix_signal_handler() is process termination. To profile VPP with MAP, the SIGPROF handler should be left as default, and MAP sampler will overwrite it with its own implementation.

2020-02-06vlib: add plugin override supportDave Barach1-0/+2
Allow a plugin to override (suppress loading of) other plugins. This mechanism allows a developer to prevent specific plugins from being loaded. To do so, provide an "overrides" list in the plugin definition: VLIB_PLUGIN_REGISTER () = { <snip> .overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so", }; or some such. Simply list the plugins in question as shown above. The .overrides structure member is limited to 256 octets. The named .elf section mechanism used to discover the vlib_plugin_registration_t's precludes the use of a variable-length array of strings. Use the vlib log to eliminate plugin and built-in vat plugin loader console spew. Added vlib_log_register_class_rate_limit(...) to allow procedural configuration of the log rate-limit. We *never* want to rate-limit plugin loader messages. Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0a9327b8cf5508482f057342783252112cb44170

2019-05-16init / exit function orderingDave Barach1-2/+7
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2018-06-26add backtrace in unix_signal_handlerKingwel Xie1-9/+49
crash stack backtrace will be directed to syslog 1. make use of glic backtrace in execinfo.h. the old clib_backtrace is removed 2. install SIGABRT in signal handler, but have to remove it when backtrace is done. reason is to capture stack trace caused by SIGABRT. vPP ASSERT always call os_exit then abort(). we definitely want to know the trace of this situation. It is a little tricky to avoid SIGABRT infinite loop 3. always load symbols by calling clib_elf_main_init () in main(). Otherwise, PC addresses instead of symbols will be displayed.

2017-04-06Use thread local storage for thread indexDamjan Marion1-24/+19
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.

2017-02-03Plugin infrastructure improvementsDamjan Marion1-0/+8
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>
