RELEASE NOTES
|
|
FreeBSD Release 3.0-SNAPSHOT
|
|
|
|
This is a SNAPSHOT release of FreeBSD 3.0-CURRENT and is aimed primarily
|
|
at release testers. Some parts of the documentation may not be updated
|
|
yet and should be reported if and when seen. Naturally, any installation
|
|
failures or crashes should also be reported ASAP by sending mail to
|
|
freebsd-bugs@FreeBSD.org or using the send-pr command (those preferring a
|
|
WEB based interface can also see http://www.freebsd.org/send-pr.html).
|
|
|
|
For information about FreeBSD and the layout of the 3.0-SNAPSHOT release
|
|
directory (especially if you're installing from floppies!), see ABOUT.TXT.
|
|
For installation instructions, see the INSTALL.TXT and HARDWARE.TXT files.
|
|
|

|
|
1. What's new since 2.2.X-RELEASE
|
|
------------------------------------
|
|
|
|
KERNEL CHANGES:
|
|
|
|
The code from 4.4BSD-Lite2 has been (finally) merged.
|
|
|
|
The SMP (Symmetric MultiProcessing) branch has been merged.
|
|
|
|
Secure RPC is now supported (and usable with NFS et al).
|
|
|
|
Sun's WEBNFS standard is now supported.
|
|
|
|
Use the new if_multiaddrs list for multicast addresses rather than the
|
|
previous hackery involving struct in_ifaddr and arpcom. Get rid of the
|
|
abominable multi_kludge.
|
|
|
|
The new if_media selection method for ethernet drivers has been brought
|
|
in, obtained from Jason Thorpe's implementation for NetBSD.
|
|
|
|
Multi-session ISO-9660 CD-ROMs are now fully supported. By default, the
|
|
last session will be mounted (including for root mounts). For non-root
|
|
mounts, mount_cd9660(8) can take an argument to mount a particular
|
|
session instead of the default one.
|
|
|
|
The UPAGES are gone from the per-process address space which allows
|
|
complete address space and page table sharing by reference count.
|
|
|
|
Newly forked child processes return directly to user mode rather than
|
|
return up through the fork() syscall tree. This eliminates the kernel
|
|
stack copy at fork time and simplifies certain other internal operations.
|
|
It is also needed to support the removal of the UPAGES. (The idea for
|
|
this originally came from NetBSD, but we did it for different reasons.)
|
|
|
|
vfork() is now fully functional by taking advantage of the new sharing
|
|
semantics and a significant speedup has been measured. This can be
|
|
disabled via the kern.fast_vfork sysctl variable in case of problems.
|
|
Statically linked binaries from older releases and other BSD platforms
|
|
are a problem since there was a bug in the 4.4BSD (net2, Lite and Lite2)
|
|
popen() implementation.
|
|
|
|
With the contribution of Berkeley Software Design, Inc., Jonathan Lemmon,
|
|
Mike Smith, Sean Eric Fagan, and John Dyson, VM86 support has been added
|
|
to the kernel, and BSD/OS's contributed dosemu has been ported.
|
|
|
|
The SA_NOCLDWAIT flags has been implemented, featuring the System V
|
|
option where a process can express its wish to never get zombies for
|
|
dead children.
|
|
|
|
|
|
SECURITY CHANGES:
|
|
|
|
7/29 Lots of lpr/lpd security fixes merged from OpenBSD.
|
|
8/22 buffer overflows in tip corrected (benign since tip isn't
|
|
set[ug]id)
|
|
8/26 buffer overflow in glob fixed, no know exploits
|
|
8/27 vacation security problem with sendmail corrected (SNI)
|
|
8/29 inetd sleeps less when children exit, making DoS attacks much
|
|
harder.
|
|
8/29 fts now race-proof and find -execdir added (-current only)
|
|
|
|
The suidperl vulnerability mentioned in the CERT advisory CA-97.17 is
|
|
also believed to be fixed.
|
|
|
|
|
|
USERLAND CHANGES:
|
|
|
|
The default username length has increased to 16 characters.
|
|
Caution: Old utmp/wtmp files will NOT work with this change since
|
|
the data records will be of the old size. For a conversion utility
|
|
to aid with this, see /usr/src/tools/3.0-upgrade.
|
|
|
|
/etc/sysconfig now replaced by more compact /etc/rc.conf file
|
|
(new since 2.2.1).
|
|
|
|
fdisk(8) now numbers disk slices from 1 to 4 rather than from 0 to 3.
|
|
This brings it in line with the numbers used in the device names
|
|
in /dev.
|
|
|
|
|
|
2. Supported Configurations
|
|
---------------------------
|
|
|
|
FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus
|
|
based PC's, ranging from 386sx to Pentium class machines (though the
|
|
386sx is not recommended). Support for generic IDE or ESDI drive
|
|
configurations, various SCSI controller, network and serial cards is
|
|
also provided.
|
|
|
|
What follows is a list of all peripherals currently known to work with
|
|
FreeBSD. Other configurations may also work, we have simply not as yet
|
|
received confirmation of this.
|
|
|
|
|
|
2.1. Disk Controllers
|
|
---------------------
|
|
|
|
WD1003 (any generic MFM/RLL)
|
|
WD1007 (any generic IDE/ESDI)
|
|
IDE
|
|
ATA
|
|
|
|
Adaptec 1535 ISA SCSI controllers
|
|
Adaptec 154x series ISA SCSI controllers
|
|
Adaptec 174x series EISA SCSI controller in standard and enhanced mode.
|
|
Adaptec 274X/284X/2940/3940 (Narrow/Wide/Twin) series ISA/EISA/PCI SCSI
|
|
controllers.
|
|
Adaptec AIC7850 on-board SCSI controllers.
|
|
|
|
Adaptec AIC-6260 and AIC-6360 based boards, which includes the AHA-152x
|
|
and SoundBlaster SCSI cards.
|
|
|
|
** Note: You cannot boot from the SoundBlaster cards as they have no
|
|
on-board BIOS, such being necessary for mapping the boot device into the
|
|
system BIOS I/O vectors. They're perfectly usable for external tapes,
|
|
CDROMs, etc, however. The same goes for any other AIC-6x60 based card
|
|
without a boot ROM. Some systems DO have a boot ROM, which is generally
|
|
indicated by some sort of message when the system is first powered up
|
|
or reset, and in such cases you *will* also be able to boot from them.
|
|
Check your system/board documentation for more details.

3. Obtaining FreeBSD
|
|
--------------------
|
|
|
|
You may obtain FreeBSD in a variety of ways:
|
|
|
|
3.1. FTP/Mail
|
|
-------------
|
|
|
|
You can ftp FreeBSD and any or all of its optional packages from
|
|
`ftp.freebsd.org' - the official FreeBSD release site.
|
|
|
|
For other locations that mirror the FreeBSD software see the file
|
|
MIRROR.SITES. Please ftp the distribution from the site closest (in
|
|
networking terms) to you. Additional mirror sites are always welcome!
|
|
Contact freebsd-admin@FreeBSD.org for more details if you'd like to
|
|
become an official mirror site.
|
|
|
|
If you do not have access to the Internet and electronic mail is your
|
|
only recourse, then you may still fetch the files by sending mail to
|
|
`ftpmail@ftpmail.vix.com' - putting the keyword "help" in your message
|
|
to get more information on how to fetch files using this mechanism.
|
|
Please do note, however, that this will end up sending many *tens of
|
|
megabytes* through the mail and should only be employed as an absolute
|
|
LAST resort!
|
|
|
|
|
|
3.2. CDROM
|
|
----------
|
|
|
|
FreeBSD 3.0-SNAP and 2.2.x-RELEASE CDs may be ordered on CDROM from:
|
|
|
|
Walnut Creek CDROM
|
|
4041 Pike Lane, Suite D
|
|
Concord CA 94520
|
|
1-800-786-9907, +1-510-674-0783, +1-510-674-0821 (FAX)
|
|
|
|
Or via the Internet from orders@cdrom.com or http://www.cdrom.com.
|
|
Their current catalog can be obtained via ftp from:
|
|
|
|
ftp://ftp.cdrom.com/cdrom/catalog
|
|
|
|
Cost per -RELEASE CD is $39.95 or $24.95 with a FreeBSD subscription.
|
|
FreeBSD 3.0-SNAP CDs are $39.95 or $14.95 with a FreeBSD-SNAP subscription
|
|
(-RELEASE and -SNAP subscriptions are entirely separate). With a
|
|
subscription, you will automatically receive updates as they are released.
|
|
Your credit card will be billed when each disk is shipped and you may cancel
|
|
your subscription at any time without further obligation.
|
|
|
|
Shipping (per order not per disc) is $5 in the US, Canada or Mexico
|
|
and $9.00 overseas. They accept Visa, Mastercard, Discover, American
|
|
Express or checks in U.S. Dollars and ship COD within the United
|
|
States. California residents please add 8.25% sales tax.
|
|
|
|
Should you be dissatisfied for any reason, the CD comes with an
|
|
unconditional return policy.
|
|
|
|
|
|
4. Reporting problems, making suggestions, submitting code.
|
|
-----------------------------------------------------------
|
|
|
|
Your suggestions, bug reports and contributions of code are always
|
|
valued - please do not hesitate to report any problems you may find
|
|
(preferably with a fix attached, if you can!).
|
|
|
|
The preferred method to submit bug reports from a machine with
|
|
Internet mail connectivity is to use the send-pr command or use the CGI
|
|
script at http://www.freebsd.org/send-pr.html. Bug reports
|
|
will be dutifully filed by our faithful bugfiler program and you can
|
|
be sure that we'll do our best to respond to all reported bugs as soon
|
|
as possible. Bugs filed in this way are also visible on our WEB site
|
|
in the support section and are therefore valuable both as bug reports
|
|
and as "signposts" for other users concerning potential problems to
|
|
watch out for.
|
|
|
|
If, for some reason, you are unable to use the send-pr command to
|
|
submit a bug report, you can try to send it to:
|
|
|
|
freebsd-bugs@FreeBSD.org
|
|
|
|
Note that send-pr itself is a shell script that should be easy to move
|
|
even onto a totally different system. We much prefer if you could use
|
|
this interface, since it make it easier to keep track of the problem
|
|
reports. However, before submitting, please try to make sure whether
|
|
the problem might have already been fixed since.
|
|
|
|
|
|
Otherwise, for any questions or tech support issues, please send mail to:
|
|
|
|
freebsd-questions@FreeBSD.org
|
|
|
|
|
|
Additionally, being a volunteer effort, we are always happy to have
|
|
extra hands willing to help - there are already far more desired
|
|
enhancements than we'll ever be able to manage by ourselves! To
|
|
contact us on technical matters, or with offers of help, please send
|
|
mail to:
|
|
|
|
freebsd-hackers@FreeBSD.org
|
|
|
|
|
|
Please note that these mailing lists can experience *significant*
|
|
amounts of traffic and if you have slow or expensive mail access and
|
|
are only interested in keeping up with significant FreeBSD events, you
|
|
may find it preferable to subscribe instead to:
|
|
|
|
freebsd-announce@FreeBSD.org
|
|
|
|
|
|
All of the mailing lists can be freely joined by anyone wishing
|
|
to do so. Send mail to MajorDomo@FreeBSD.org and include the keyword
|
|
`help' on a line by itself somewhere in the body of the message. This
|
|
will give you more information on joining the various lists, accessing
|
|
archives, etc. There are a number of mailing lists targeted at
|
|
special interest groups not mentioned here, so send mail to majordomo
|
|
and ask about them!
