sys/sys unpcb.h
Log:
Merge unpcb.h:1.20 from HEAD to RELENG_6:
Add two new unpcb flags, UNP_BINDING and UNP_CONNECTING, which will be
used to mark UNIX domain sockets as being in the process of binding or
connecting. Use these to prevent simultaneous bind or connect
operations by multiple threads or processes on the same socket at the
same time, which closes race conditions present in the UNIX domain
socket implementation since inception.
