2020-02-06vlib: add plugin override supportDave Barach1-0/+5
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

How to use: plugins { plugin default {disable} plugin dpdk_plugin.so {enable} plugin acl_plugin.so {enable} } It also preserves the old behavior. Change-Id: I9901c56d82ec4410e69c917992b78052aa6a99e0 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2017-11-18Call a plugin init function by nameDave Barach1-0/+26
Use this macro to arrange init function ordering between friend plugins. Fails in the usual manner if the plugin doesn't exist, or if the init function symbol is AWOL. clib_error_t * thisplug_init (vlib_main_t *vm) { clib_error_t *error = 0; if ((error = vlib_plugin_init_function ("otherplug.so", otherplug_init))) return error; <etc> return error; } VLIB_INIT_FUNCTION(thisplug_init); Change-Id: Ideecaf46bc0b1546e85096e54be8ddef87946565 Signed-off-by: Dave Barach <dave@barachs.net>

2017-02-03Plugin infrastructure improvementsDamjan Marion1-3/+28
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>
