VPN Plugins

Cmv: formatting

As of 3.0.2, VPN plugins are stored in:

* /usr/lib/vpn/agents (VPNC and Cisco AnyConnect that ship with the device)
* /media/cryptofs/apps/usr/palm/vpnframework/agents (extra such as the PPTP plugin in the App Catalog)

They have the following structure (VPNC used as an example):

* /usr/lib/vpn/agents/vpnc/ (root directory)
** [[#vpn-plugin-info.json|vpn-plugin-info.json]]
** [[#library|library]] (e.g. libVpncAgent.so)
** other ancillary files (callback scripts, etc)
** plugins/ (does NOT seem to be necessary - VPNC plugin does not have this directory)
*** plugin files (apparently only as necessary by the plugin library)

== vpn-plugin-info.json ==
{
"title": "VPNC",
"id": "com.palm.vpnc",
"version": "0.5.1",
"vendor": "Palm, Inc.",
"type": ["IPSec"],
"plugin": "libVpncAgent.so"
}

== Library ==

From objdump, it looks like the only symbols in common between every plugin are:

initVpnAgent
cleanupVpnAgent
bannerSent
gLocalizedStrList

In addition to the expected symbols from GCC. And that's it. Signatures for these functions do not seem to be documented anywhere, and I suspect gLocalizedStrList is just an array which may not be required by [[PmVpnDaemon]]. No idea about bannerSent.

There are also calls to apparently-undocumented functions such as PmLogGetContext and PmLogPrint_. The VPNC and PPTP plugins link to:
