This is a new "samples" plugin which does not do many useful things,
besides
- show how a plugin is programmed
- how the various messages get dispatched
- how to pass back information from a client-connect/v2 plugin
- how to do async-cc plugins [not yet implemented]
the operation of the plugin is controlled by UV_WANT_* environment
variables
controlled by the client ("--setenv UV_WANT_CC_FAIL 1 --push-peer-info"),
to "fail CLIENT_CONNECT" or "use async-cc for CLIENT_CONNECT_V2" or
"send 'disable' back from ...") - which is useful for automated testing
of server success/defer/fail code paths for the CLIENT_CONNECT_* functions.
See samples/sample-plugins/client-connect/README for details how to do
this.
v2:
- implement async / deferred operation both for CLIENT_CONNECT and
CLIENT_CONNECT_V2 plugin calls
- implement returning openvpn-controlled (setenv) config snippets
(so the client side can verify in automated testing that the plugin
operated correctly, without hard-coding something in the plugin code)
v3:
- remove -Wno-unused-variable from Makefile
- remove unused "char ** argv" (commented out, but kept as reference)
v4:
- upgrade to use the build infra brought by commit 0b5141d8f9
- remove local Makefile
- include "config.h" to get what is needed to get rid of the strdup()
