|
||
WHAT'S NEW IN THIS RELEASE (preliminary list)
|
||
=============================================
|
||
|
||
4.4 Lite
|
||
--------
|
||
As previously stated, this release is based entirely on CSRG's
|
||
latest (and last) BSD release - 4.4 Lite. This features as number
|
||
of improvements over 4.2BSD (Net/2), not least of which are:
|
||
|
||
o Legal approval of Novell & U.C. Berkeley. After the settlement
|
||
of the longstanding lawsuit between USL/UCB/Novell/BSDI, all
|
||
parties were (strongly) encouraged to move to 4.4 Lite in order
|
||
to avoid future legal entanglements. The fact that we've now done
|
||
so should make this release much more attractive to potential
|
||
commercial users.
|
||
|
||
o Many new filesystem types, such as stackable filesystems, union
|
||
filesystems, "portals", kernfs, a simple log-structured filesystem, a
|
||
new version of NFS (NQNFS), etc. While some of these new filesystems
|
||
are also rather unpolished and will require significant additional
|
||
work to be truly robust, they're a good start.
|
||
|
||
o 64bit offsets, allowing filesystems of up to 2^63 bytes in size.
|
||
|
||
o Further work towards full POSIX compliance.
|
||
|
||
|
||
And many many other features. For more documentation, it is recommended
|
||
that you purchase the 4.4BSD Document Set from O'Reilly Associates and the
|
||
USENIX Association. ISBN 1-56592-082-1
|
||
|
||
|
||
IP multicast support
|
||
--------------------
|
||
|
||
The IP multicast support has been upgraded from the woefully ancient
|
||
1.x code in 4.4-Lite to the most current and up-to-date 3.3 release
|
||
from Steve D. and Ajit. The non-forwarding code is known to work (for
|
||
some limited test cases). The multicast forwarder and user-mode
|
||
multicast routing process are known to compile, but have not been
|
||
significantly tested (hopefully this will happen before 2.0 release).

|
||
Loadable Kernel Modules
|
||
-----------------------
|
||
|
||
David Greenman incorporated NetBSD's port of Terry Lambert's loadable
|
||
kernel module support. Garrett Wollman wrote the support for loadable
|
||
file systems, and S<>ren Schmidt did the same for loadable execution
|
||
classes.
|
||
|
||
Owner: core
|
||
Sources involved: sys/kern, sbin/modload, sbin/modunload,
|
||
usr.bin/modstat
|
||
|
||
|
||
Loadable filesystems
|
||
--------------------
|
||
|
||
Most filesystems are now dynamically loadable on demand, with the
|
||
exception of the UFS family (FFS, LFS, and MFS). With the exception
|
||
of NFS, all such filestystems can be unloaded when all references are
|
||
unmounted. To support this functionality, the getvfsbyname(3)
|
||
family of functions has been added to the C library and the lsvfs(1)
|
||
command provides the same information at the shell level. Be aware of
|
||
the following current restrictions:
|
||
|
||
- /usr/bin may not reside on a dynamically loaded filesystem.
|
||
- There must be a writable /tmp directory available
|
||
before filesystems are loaded (moving / to the top of your
|
||
/etc/fstab file will accomplish this).
|
||
- Some of the more esoteric filesystems simply don't work when loaded
|
||
dynamically (though they often don't work "static", either.)
|
||

||

|
||
|
||
|
||
S/Key
|
||
-----
|
||
|
||
Since version 1.1.5, FreeBSD has supported the S/Key one time password scheme.
|
||
The version used is derived from the logdaemon package of Wietse Venema.
|
||
Some of the features new in 2.0 are:
|
||
- New access control table format to impose the use of S/Keys
|
||
based on: hostname, ip address, port, username, group id.
|
||
- S/Key support can be disabled by not having the access control
|
||
table.
|
||
The second item explains the absence of skey.access in the installed /etc.
|
||
To enable S/Key support, create a file skey.access in /etc and fill it
|
||
according to your needs. See also skey.access(5) and the example in
|
||
/usr/share/examples/etc/skey.access.
|
||
|
||
Owner: pst, guido
|
||
Sources involved: lib/libskey, usr.bin/key* (plus patches to others)
|
||
|
||
|
||
TCP/IP over parallel (printer) port
|
||
-----------------------------------
|
||
|
||
You can now run TCP/IP over a standard LapLink(tm) cable, if both ends
|
||
have a interrupt-driven printerport. The interface is named "lp0"
|
||
where '0' is the same as the lpt# unit number. This is not compatible
|
||
with PLIP. If you run NFS, try setting MTU to 9180, otherwise leave
|
||
it at 1500 unless you have a good reason to change it. Speed varies
|
||
with the CPU-type, with up to 70 kbyte/sec having been seen and 50
|
||
kbyte/sec being the norm.
|
||
|
||
Owner: phk
|
||
Sources involved: isa/lpt.c
|
||
|
||
|
||
ProAudioSpectrum SCSI-driver
|
||
----------------------------
|
||
|
||
If you have a PAS board with a CD-ROM, and the MS-DOS driver is called
|
||
TSLCDR.SYS, then the "pas" driver should work on your card. You can
|
||
attach disks, cdroms and tapes, but due to the nature of the hardware
|
||
involved, the transfer rate is limited to < 690 kbyte/sec. For CD-ROM
|
||
use, this is generally more than enough.
|
||
|
||
Owner: phk
|
||
Sources involved: isa/pas.c
|
||
|
||
|
||
Gzip'ed binaries
|
||
----------------
|
||
|
||
We have an experimental implementation for direct execution of gzip'ed
|
||
binaries in this release. When enabled, it allows you to simply gzip
|
||
your binaries, remove the '.gz' extension and make the file
|
||
executable. There is a big speed and memory consumption penalty for
|
||
doing this, but for laptop users it may be worthwhile. The maximum
|
||
savings are generally around 10 Mb of disk space.
|
||
|
||
Owner: phk
|
||
Sources involved: kern/imgact_gzip.c kern/inflate.c
|
||
|
||
|
||
Diskless booting
|
||
----------------
|
||
|
||
Diskless booting it in 2.0 and much improved since 1.1.5. The boot-program
|
||
is in src/sys/i386/boot/netboot, and can be run from a MSDOS system or
|
||
burned into an EPROM. Local swapping is possible. Presently WD, SMC and
|
||
Novell cards are supported.
|
||
|
||
Owner: Martin Renters & phk
|
||
Sources involved: i386/boot/netboot, sys/nfs/nfs_vfsops.h
|
||
|
||
|
||
Device configuration database
|
||
-----------------------------
|
||
|
||
The kernel now keeps better track of which device drivers are active and
|
||
where the devices are attached; this information is made available to
|
||
user programs via the new sysctl(3) management interface. Current
|
||
applications include lsdev(8), which lists the currently configured
|
||
devices. In the future, we expect to use this code to automatically
|
||
generate a configuration file for you at installation time.
|
||
|
||
Owner: wollman
|
||
Sources involved: sys/i386, sys/scsi, sys/kern/kern_devconf.c,
|
||
sys/sys/devconf.h, usr.sbin/lsdev
|
||
|
||
|
||
Kernel management interface
|
||
---------------------------
|
||
|
||
With 4.4-Lite, we now have a better management interface for the endless
|
||
series of kernel variables and parameters which were previously manipulated
|
||
by reading and writing /dev/kmem. Many programs have been rewritten to
|
||
use this interface, although many old-style programs still remain. Some
|
||
variables which were never accessible before are now available through
|
||
the sysctl(1) program. In addition to the standard 4.4BSD MIB variables,
|
||
we have added support for YP/NIS domains (kern.domainname), controlling
|
||
the update daemon (kern.update), retrieving the OS release date
|
||
(kern.osreldate), determining the name of the booted kernel (kern.bootfile),
|
||
and checking for hardware floating-point support (hw.floatingpoint).
|
||
We have also added support to make management queries of devices and
|
||
filesystems.

|
||
Sources involved: sys, usr.bin/sysctl
|
||
|
||
|
||
iBCS2 support
|
||
-------------
|
||
|
||
FreeBSD now supports running iBCS2 compatible binaries (currently
|
||
SCO UNIX 3.2.2 & 3.2.4 and ISC 2.2 COFF format are supported).
|
||
The iBCS2 emulator is in its early stages, but it is functional, we
|
||
havn't been able to do exhaustive testing (lack of commercial apps),
|
||
but allmost all of SCO's 3.2.2 binaries are working, so is an old
|
||
INFORMIX-2.10 for SCO. Further testing is nessesary to complete this
|
||
project. There is also work under way for ELF & XOUT loaders, and
|
||
most of the svr4 syscall wrappers have been written.
