Sendmail 8.12.10 and BIND 8.3.7-REL are in, thanks to David Rhodus.
The kernel option USER_LDT is now on by default, as it’s useful for ports like Wine, or mplayer, and will be needed for threading. Suggested by Craig Dooley.
The Marvell Yukon chipset now supports multicast. A small thing, but I’m hurting for news.
Matt Dillon’s updated RCNG in a big way. You can now check the status of, or start, stop, etc. different system services using appropriate single commands like
rcrestart, and so on.
varsym -sa will list service status.
The old way had you looking for the appropriate file in
/etc/rc.d and issing commands for it, and having to poke throught
ps -ax or
/var/run/ to see what’s going.
To get this running, do
make upgrade_etc in
/usr/src/etc, or a regular build/installworld. Also, install
/usr/src/sbin/rcrun, and reboot.
Jeffrey Hsu has added a rather complex patch for
sendfile(2); I’m going to link to the changelog rather than sum up.
Ryan Dooley’s patch giving stack-smashing protection in libc is in. It’s not on by default. It adds some overhead but little binary size when turned on.
Craig Dooley submitted a patch to add a number of improvements to agp, from FreeBSD5.
Code to add the lnc and vx network drivers from FreeBSD-5 is in, put together by Joerg Sonnenberger. This is part of the PCI compat cleanup, though these just-added drivers just use newbus.
Libcaps, the library for userland threading, has been updated. Work is still proceeding on fp stave/restore, and some other tasks, including Galen Sampson’s work. Matt Dillon’s commit message sums it up as neatly as possible, so I’ll just paste it:
Major update to libcaps. Implement support for virtual cpus using
rfork_thread() and implement IPIs, per-virtual-cpu globaldata areas,
and per-virtual-cpu LWKT scheduling.
Galen Sampson and Matt Dillon have committed the first stage of the userland threading – globaldata structure and thread primitives are connected, and libcaps can lock in a fashion similar to the existing kernel locks.
/usr/src/nrelease has the ability to build the new ‘live’ CD iso images. Listed here is what Matt Dillon listed as possible make targets in that directory:
“release: This will do a full buildworld and buildkernel (GENERIC)
with the current source tree, then generate the release
ISO and directory structure in /usr/release.
quickrel: This will do a ‘quick’ buildworld and buildkernel (i.e.
-DNOCLEAN) and then generate the release ISO and directory
structure in /usr/release.
realquickrel: This is even faster. It assumes that the buildkernel and
buildworld have already been done and just generates the ISO
directory structure and ISO file in /usr/release.”
David Rhodus has checked in a new version of BIND, which may correct the recently discovered possible DoS. (commit notes don’t specify.)
Matt Dillon has added in a new ‘libcaps’ library, mostly for experimentation, which appears to be the base for userland threading.

Matt Dillon added an “upcall mechanism to support userland LWKT”. You can look at the man page for upc_register in source.
Aaaand it’s done – rebuilding your system with current sources will give you a
uname that reports “DragonFly”. Through some trickery, most ports are apparently not broken by this.
The make release step no longer depends on perl, thanks to Jeroen Ruigrok.
I’ll quote Matt Dillon’s entry cause I’m working late:
” The MBWTest program (/tmp/mbw1) attempts to figure out the L1 and L2 cache sizes and measures L1, L2, and non-cached linear memory bandwidth.”
Matt Dillon’s added boot code from FreeBSD 5 – this allows AMD64 and ELF64 support. He also pushed in new linker code and some (not yet enabled) support for UFS2.
Use installkernel and installworld as part of your build process, and you should be fine with these changes. However, you will manually have to copy
There’s been a lot of new code lately – that’s good!
Variant symlinks are possible now, though you currently have to set the sysctl vfs.varsym_enable. ‘varsym’ can be used to mess with them at any time, however.
