2023-04-12vlib dhcp: default to logging without elogsFlorin Coras1-1/+1
Some components, like dhcp, log constantly changing strings which in turn forces elog string table to grow unbound. To avoid this, as a workaround, only turn on elog logging if requested. Actual fix that adds configuration for logging subclasses should come in a later patch.

2022-07-06misc: pass NULL instead of 0 for pointer in variadic functionsAndreas Schultz1-4/+3
0 is not NULL (at least not in all cases), passing 0 into a variadic function in a place where the consumer reads it as pointer might leave parts of the pointer uninitilized and hence filled with random data. It seems that this used to work with gcc, but clang seems to treat the 0 in those places as a 32bit integer.

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

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>
