drbd: Always use the same protocol version for the same peer · 0916e0e3

Andreas Gruenbacher authored Mar 21, 2011

There is no need to send protocol 80 headers to peers that understand
protocol 95 headers. Make sure that we don't send protocol 95 headers
until we have agreed upon a protocol version with our peer, though.

drbd: Introduce and use drbd_recv_all_warn() · a5c31904

Andreas Gruenbacher authored Mar 24, 2011

The pattern of receiving a fixed number of bytes and warning if a short
packet is received and the receiver has not actively been interruped is
repeated many times; clean that up.
