2020-02-06vlib: add plugin override supportDave Barach1-31/+178
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

2018-03-26plugin: Add plugin 'default' disable/enableMohsin Kazmi1-0/+10
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>

2017-04-26Exit if plugin load attempt failDamjan Marion1-6/+2
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>

2017-02-26Load plugins in alphabetical orderDave Barach1-9/+55
API traces contain absolute message numbers. Loading plugins in directory (vs. alphabetical) order makes trace replay fragile. Change-Id: I46b3a3b6a9843a383d42269fca0cf5a789486eaf Signed-off-by: Dave Barach <dave@barachs.net>

2017-02-03Plugin infrastructure improvementsDamjan Marion1-57/+282
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>
