Hi all,
this is the first official submission of the ovpn-dco support for
OpenVPN 2. This patchset is ready for review (and possible merge).
Please have a look, test and try to break it!
What has changed from the RFCv2 (sent on Jan 14th):
* DCO API has been modified to allow specifying a value for mssfix.
However only ovpn-dco-win will pick up this value and do something
meaningful. On linux is yet to be decided how to handle it.
* peer_add() and peer_set() have been decoupled so that the latter
can be invoked at the right time, after some parameters have been
computed (i.e. mssfix).
* routes and iroutes are now installed with a default metric of 200
for the former and 100 for the latter. this guarantees that iroutes
always have higher priority (iroutes are basically routes with a
specific nexthop).
* The ovpn-dco interface is now configured in p2p mode when launching
OpenVPN as client or p2p, while it is configured in mp (multipeer)
mode when launching OpenVPN in server mode.
* Reverse Path Filtering is now enabled automatically when the interface
is configured in mp mode (this is a change in ovpn-dco itself).
* some more intra-OpenVPN DCO API polishing.
* a few minor things I may not be recalling now...
A working copy of this patchset, always based on top of laest master, is
available in the OpenVPN repo in the "dco" branch.
Thanks a lot!
