2020-11-26vlib: fix vlib log elog vector overrunBenoît Ganne1-1/+1
vlib log strings are vectors not necessarily null-terminated C-string. Type: fix Fixes: bc867c3d2137dab4b1395196c1936233517980ab Change-Id: Ia805ecdf4e76ccb1001dc93647161ee1c3adebc9 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-10-21vlib: print logs to stderr if interactive or nosyslog setDamjan Marion1-46/+98
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>
2020-02-06vlib: add plugin override supportDave Barach1-3/+17
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

2019-07-08api: Implement log_dump/log_detailsPaul Vinciguerra1-52/+1
- Replaces the need to screen scrape "show log". - Adds an api to return the system time.

2018-08-25Add int cast to fit '.*' printf expectationsPierre Pfister1-4/+5
Sometimes, compiler would throw an error: error: field precision specifier ‘.*’ expects argument of type ‘int’, but argument 5 has type ‘u64 {aka long unsigned int}’ This change adds the requested cast.

2018-04-26vlib: set log tap level <level> does not work for some keywordsSteven1-2/+2
While some levels such as debug and emerg work, others don't. See below. DBGvpp# set log class tap level warn set log class tap level warn set logging class: unknown input `level warn' DBGvpp# set log class tap level debug set log class tap level debug DBGvpp# set log class tap level info set log class tap level info set logging class: unknown input `level info' DBGvpp# set log class tap level err set log class tap level err DBGvpp# set log class tap level crit set log class tap level crit set logging class: unknown input `level crit' DBGvpp# set log class tap level emerg set log class tap level emerg DBGvpp# Cause: The reason for the failure for the shorter keywords is level_str is unformatted with %v which is not null terminated. For example, the character after "info" could be anything in level_str. The memcmp with size of the macro keyword __##uc which includes the null character or 5 in this case and thus the comparison fails. Fix: Use %s which insure level_str is null terminated. Use strcmp to rule out false positve match like "debugxxx" against keyword "debug". Change-Id: I7a2d97a0f7f618df105da7eca791618dce04d21e Signed-off-by: Steven <sluong@cisco.com>
