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. + SECURITY CHANGES: 7/29 Lots of lpr/lpd security fixes merged from OpenBSD. |
