directories and Makefiles from src/usr.sbin/bind to src/lib; make
BIND libraries build shared. Saves about 1MB-1.5MB per installed
executable, about 5MB for a base+etc minimal installation of NetBSD.
Do not say that one should extract etc.tgz into a temporary directory
before running postinstall, postinstall does it itself.
Mention that sysinst runs "postinstall fix".
old, now removed sendmail. If yes, display a warning menu that offers to
replace it by a current version that selects postfix.
Thank much to Martin Husemann for extensive testing and suggestions.
XXX translations need updating.
list. I already removed the files under /usr/share/sendmail from the
obsolete list in src/distrib/sets/lists/misc/mi rev. 1.145, but forgot
about the directories. This avoids "postinstall check obsolete" failing
needlessly.
- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

instead of adding/subtracting our own IPv4 header.
There are many benefits: gre(4) needn't grok the outer encapsulation
header any longer, so this simplifies the gre(4) code. The IP
stack needn't grok GRE, so it is simplified, too. gre(4) will
benefit from optimizations in the socket code. Eventually, gre(4)
will gain an IPv6 encapsulation with very few new lines of code.
There is a small performance loss. A 133 MHz, 486-class AMD Elan
sinks/sources a TCP stream over GRE with about 93% the throughput
of the old code. TCP throughput on a 266 MHz, 586-class AMD Geode
is about 96% the throughput of the old code. A 175-MHz ADM5120
(MIPS) only sinks a TCP stream over GRE at about 90% of the old
code; I am still investigating that.
I produced stripped-down versions of sosend() and soreceive() for
gre(4) to use. They are guaranteed not to block, so they can be
called from a software interrupt and from a socket upcall,
respectively.
A kernel thread is no longer necessary for socket transmit/receive,
but I didn't get around to removing it, yet.
Thanks to Matt Thomas for suggesting the use of stripped-down socket
code and software interrupts, and to Andrew Doran for advice and
answers concerning software interrupts, threads, and performance.
