@ -92,6 +92,22 @@ the life of the sleep.
An in-kernel linker is implemented and intended to replace the lkm system
with the bogosity that goes with it.
All supported network protocols have been updated to avoid the ``big
switch'' pr_usrreq(), and to pass a process pointer down to each user
request that might need process credentials or want to sleep,
replacing the previous hodgepodge of inspecting curproc (which only
occasionally did the right thing) and the SS_PRIV socket state flag.
The latter has now been eliminated, along with the SO_PRIVSTATE socket
option which cleared it. Protocols are now also given the opportunity
to override the generic send, receive, and poll routines, which will
make it possible for a more efficient, protocol-specific
implementation of these entry points in later releases. Finally, many
parts of the network code have been modified to cease storing socket
addresses and other metainformation in mbufs, in preparation for the
eventual elimination thereof. The mechanism by which socket addresses
are now returned is still highly subject to change as we experiment to
discover the most efficient method.
