2025-04-17ovpn: add support for MSG_NOSIGNAL in tcp_sendmsgAntonio Quartulli
Userspace may want to pass the MSG_NOSIGNAL flag to tcp_sendmsg() in order to avoid generating a SIGPIPE. To pass this flag down the TCP stack a new skb sending API accepting a flags argument is introduced.

2025-04-17ovpn: implement basic TX path (UDP)Antonio Quartulli
Packets sent over the ovpn interface are processed and transmitted to the connected peer, if any. Implementation is UDP only. TCP will be added by a later patch. Note: no crypto/encapsulation exists yet. Packets are just captured and sent.
