Linux 1.0
CHANGES since 0.99 patchlevel 15:
- removed all the bugs, of course.
- networking fixes.
- more changes than I really wanted..
[original announcement below]
Linux 1.0---A better UNIX than Windows NT
Summary: Linux 1.0 released
Keywords: Linux Kernel 1.0 Academy Awards
X-Moderator-Added-Keywords: universe, end of
Finally, here it is. Almost on time (being just two years late is
peanuts in the OS industry), and better than ever:
Linux kernel release 1.0
This release has no new major features compared to the pl15 kernels, but
contains lots and lots of bugfixes: all the major ones are gone, the
smaller ones are hidden better. Hopefully there are no major new ones.
The Linux kernel can be found as source on most of the Linux ftp-sites
under the names
linux-1.0.tar.gz (full source)
linux-1.0.patch.pl15.gz (patch against linux-0.99pl15)
linux-1.0.patch.alpha.gz (patch from linux-pre-1.0)
This release finally moves Linux out of Beta status and is meant as a
base for distributions to build on. It will neither change Linux'
status as FreeWare under the GPL, nor will it mean the end of
development on Linux. In fact many new features where held back for
later releases so that 1.0 could become a well tested and hopefully
stable release.
The Linux kernel wouldn't be where it is today without the help of lots
of people: the kernel developers, the people who did user-level programs
making linux useful, and the brave and foolhardy people who risked their
harddisks and sanity to test it all out. My thanks to you all.
(Editorial note: if you think this sounds too much like the Academy
Awards ceremony, just skip this: it's not getting any better.)
Thanks to people like Aaron Kushner, Danny ter Haar and the authors of
the AnwenderHandbuch (and others) who have helped me with hardware or
monetary donations (and to the Oxford Beer Trolls and others who took
care of the drinkware). And thanks to Dirk, who helped me write this
announcement despite my lazyness ("hey, it's just another release, who
needs an announcement anyway?").
To make a long and boring story a bit shorter and boring, here is at
least a partial list of people who have been helping make Linux what it
is today. Thanks to you all,

pl15a fixes the buffer cache growing problem, adds emulation for a
few unimportant floating point instructions (i287 instructions that
are No-Ops on the i387, so "emulating" them is easy :^) and fixes a
silly bug when mmap'ing stuff write-only. It also fixes a buggy lock
in the networking.

[PATCH] Linux-0.99.15 (February 2, 1994)
sbpcd (Sound Blaster Pro CD interface) driver.
Andries Brouwer cleans up and re-does keyboard driver diacritical handling.
Lots of new sound drivers.
Sysvfs added (Xenix, SystemV/386 and Coherent support). Linux was
starting to have a lot of users move over..
MAP_ANONYMOUS flag added to mmap().
Loadable modules added.
Alan Cox is active in networking.
[original changelog below]
Linux 0.99.15 released: Codefreeze for 1.0
People who look into my directory on ftp.funet.fi will already have
noticed that the latest version of linux (0.99.15) is available, and I
assume it will be available on most other linux sites soon. As
explained in a previous announcement, 0.99.15 is "it", in that this will
be the base for 1.0 after about a month of testing. No further patches
are accepted until the 1.0 release, unless they obviously fix a serious
bug.
**** NOTE 1 ****
For this code-freeze to be effective yet still potential bugs be
found, testing is needed, along with good reports of errors and
problems. Thus, nobody should think "hey, the *real* release will be
out in a month, let's wait for that", but instead think: "hey, I'd
better test this one, so that the *real* release won't result in any
ugly surprises for me".
In short: test it out, preferably even more than you usually do. Run
"crashme" for the whole month if you have the CPU-power to spare,
and/or just misuse your machine as badly as you can. And if there are
problems, report them to me (and the better the report, the more
likely I am to be able to do something about it).
**** NOTE 2 ****
Bumping the linux version number to 1.0 doesn't mean anything more
than that: it's only a version number change. More explicitly, it
does *NOT* mean that linux will become commercial (the copyright will
remain as-is), nor does it mean that development stops here, and that
1.0 will be anything special in that respect.
I'm also afraid that just changing the version number will not make
potential bugs magically disappear: this has been amply proven by
various software houses over the years. This code-freeze is there in
order to avoid most of the problems that people sometimes associate
with "X.0 releases", and I hope that it will mean that we have a
reasonably stable release that we can call 1.0 and one that I won't
have to be ashamed of.
Ok, enough said, I hope. The pl15 release is hopefully good, but I'll
continue to make ALPHA patches against it along the whole month as
problems crop up. The networking code has been much maligned, and is
not perfect by far yet, but it's getting its act together thanks to
various developers and testers. And as wiser men than I have said (or
if they haven't, they should have):
"There is life after 1.0"
Any rumors that the world is coming to an end just because I'm about to
release a 1.0-version are greatly exaggerated. I think.
Linus
----------
Things that remained the same between 0.99.14 and 0.99.15:
- I again forgot to update the README before uploading the release. In
pl14, I talked about pl13, while the all new and improved README has
now caught up with pl14. Remind me to buy a new brain one of these
days.
Changes between versions 0.99.14 and 0.99.15:
- improved Pentium detection. Some of you may have had linux report
your 4086DX2 as a pentium machine, but the new kernel will tell you
the sad truth. Whee.
- Network driver updates by Donald Becker. New drivers added, old ones
updated.
- FPU emulation updates by Bill Metzenthen. Various minor errors and
misfeatures fixed (mostly error handling).
- Support for the SoubdBlaster Pro CD-ROM driver added by Eberhard
Moenkeberg.
- extended support for keyboard re-definition, along with font
re-programming (Eugene Crosser, Andries Brouwer et al).
- tty handling fixes: true canonical mode with most features supported
by Julian Cowley. This may make your canonical mode behave funnily
if you happen to use old and broken programs that happened to work
with the old and broken behaviour (this includes at least some
'getty' programs).
- serial driver changes and tty fixes by Theodore Ts'o.
- SCSI fixes by Drew Eckhardt, Eric Youngdale, Rik Faith, Kai Mdkisara
et al.
- Updated sound card driver to version 2.4 (Hannu Savolainen)
- COFF binary loading support (but you will still need the experimental
iBCS2 patches to run non-linux i386 COFF binaries) by Al Longyear.
- Upgraded ext2fs filesystem routines (0.4a -> 0.4b), with new
features. Read the fs/ext2/CHANGES file for details. Remy Card and
Stephen Tweedie. Get a new fsck that knows about the new features.
- pipe behaviour fixed in the presense of multiple writers (now
actually conforms to POSIX specs about atomic writes). Much of the
code by Florian Coosmann.
- minix filesystem extended to support the clean flag: get a new fsck
that knows about it.
- System V filesystem (support for Xenix, Coherent and SysV
filesystems) by Doug Evans, Paul Monday, Pascal Haible and Bruno
Haible.
- loadable modules (various authors, don't remember original author of
the "modules" code).
- Lots of networking fixes by various people: Alan Cox, Charles
Hedrick, me and various other people. Non-byte-aligned networks
work, and the networking code should be much stabler in general.
+ various bugfixes and enhacements here and there (mcd driver update by
Jon Tombs, atixlmouse fix by Chris Colohan, /dev/full by XXX etc etc)
All in all, the patches come out to 1.5MB uncompressed (about 400kB
gzip-9'd), so there is little or no idea to make patches to plain pl14
available. Incremental patches and ALPHA-releases can be found on
ftp.funet.fi: pub/OS/Linux/PEOPLE/Linus/ALPHA-pl14.
Linus Torvalds [Fri, 23 Nov 2007 20:09:19 +0000 (15:09 -0500)]
This is a general announcement of the imminent code-freeze that will
hopefully make linux 1.0 a reality. The plan has been discussed a bit
with various developers already, and is already late, but is still in
effect otherwise.
In short, the next version of linux (0.99.15) will be a "full-featured"
release, and only obvious bug-fixes to existing features will be applied
before calling it 1.0. If this means that your favourite feature or
networking version won't make it, don't despair: there is life even
after beta (and it's probably not worth mailing me about it any more:
I've seen quite a few favourite features already ;-).
In fact, 1.0 has little "real meaning", as far as development goes, but
should be taken as an indication that it can be used for real work
(which has been true for some time, depending on your definition of
"real work"). Development won't stop or even slow down: some of it has
even been shelved pending a 1.0 already.
Calling it 1.0 will not necessarily make all bugs go away (quite the
opposite, judging by some other programs), but I hope it will be a
reasonably stable release. In order to accomplish this, the code-freeze
after 0.99.15 will be about a month, and I hope people will test out
that kernel heavily, instead of waiting for "the real release" so that
any potential bugs can be found and fixed.
As to where we are now: as of this moment, the latest release is the 'r'
version of pl14 (aka "ALPHA-pl14r"). I've made ALPHA releases available
on ftp.funet.fi almost daily, and expect a final pl15 within a few more
days. Testing out the ALPHA releases is not discouraged either if you
like recompiling kernels every day or two..
And finally: we also try to create a "credits" file that mentions the
developers of the kernel and essential linux utilities. The credit file
compilator is jmartin@opus.starlab.csc.com (John A. Martin), and if you
feel you have cause to be mentioned in it, please contact him.

[PATCH] Linux-0.99.13 (September 19, 1993)
We get enable_irq()/disable_irq()
The C++ experiment is not going well. Get rid of the 'extern "C"', but
replace it with an "asmlinkage" #define that allows us to experiment.
ELF binary support it a notable change.
Original ChangeLog:
- the bad memory management one-liner bug in pl12 is naturally fixed.
- compiled with plain C by default instead of C++
- ELF binary support (Eric Youngdale)
- Quickport mouse support (and some changes to the PS/2 mouse driver)
by Johan Myreen and co)
- core file name change ("core" -> "core.xxxx" where xxxx is the name
of the program that dumped code). Idea from ???. Also, core-files
now correctly truncate any existing core file before being written.
- some mmap() fixes: better error returns, and handling of non-fixed
maps for /dev/mem etc.
- one kludgy way to fix the wrong arp packets that have plagued net-2d
(resulting in arp packets that had the first four bytes of the
ethernet address as the IP address).
- I fixed the mount-point handling of 'rename()' and 'unlink()/rmdir()'
so that they should now work and/or give appropriate error messages.
An early version of this patch was already sent to the KERNEL
channel, which fixed the rename problem but not a similar bug with
unlink.
- packet mode fixes by Charles Hedrick. Sadly, these are likely to
break old telnet/rlogin binaries, but it had to be done in order to
communicate correctly with the rest of the world.
- FPU emulator patches from Bill Metzenthen. The fprem1 insn should be
correct now (not that anybody seems to have seen the incorrect
behaviour..)
- a few fixes for SCSI (Drew and Eric)
- signal.c changes to handle multiple segments (for Wine) correctly.
- updated drivers from Donald Becker: 3c509 and AT1500 drivers, but
also some other drivers have been edited, and some networking fixes.

Very small patch to 0.99pl12
I hate to put out patches this soon after a release, but there is one
potentially major problem in pl12 which is very simple to fix.. I'm
including patches: both in plain ascii and as a uuencoded gzip file
(it's the same patch - the uuencoded one is in case there is any
newsserver that messes up whitespace).
The main patch is just the change from __get_free_page(GFP_BUFFER) into
get_free_page(GFP_KERNEL), and the two minor patches just add checks
that actually enforce the read-only nature of current file mmap'ings so
that any program that tries to do a write mapping at least will be told
that it won't work.
I'd suggest anybody compiling pl12 should add at least the file_table.c
patch: thanks to Alexandre Julliard for noticing this one.

[PATCH] Linux-0.99.12 (August 14, 1993)
CDU31A and MCD CD-ROM drivers. Ahh, the bad old days of every sound
card manufacturer having their own CD interface.
Much nicer keymaps for keyboards.
Many more network drivers by Donald Becker for the improving NET-2 code.
Eric Youngdale makes executables and libraries use the new mmap()
functionality. The old special-cased sharing goes away. Hurray! This
also means that mmap gets a lot more testing. It also means that NFS
has to be fixed to allow mmaps. Done.
"sys_modify_ldt()" appears, the extended DOS emulators want it.
Still using C++ to compile the kernel.
Original changelog:
- The memory manager cleanup has continued, and seems to be mostly
ready, as proven by the ease of adding mmap() over NFS with the new
routines. So yes, the pl12 kernel will demand-load your binaries
over NFS, sharing code and clean data, as well as running shared
libraries over NFS. Memory management by Eric and me, while the NFS
mmap code was written by Jon Tombs,
- ** IMPORTANT **: The keyboard driver has been enhanced even further,
and almost everything is completely re-mappable. This means that
there is a new version of 'loadkeys' and 'dumpkeys' that you must use
with this kernel or you'll have problems. The default keyboard is
still the US mapping, but if you want to create your own mappings
you'll have to load them with the new binaries. Get the 'kbd.tar.gz'
archive from the same place you get the kernel.
The new keymappings allow things like function key string changes,
remapping of the control keys, and freedom to remap any of the normal
keyboard functions: including special features like rebooting,
console switching etc. The keyboard remapping code has been done
mostly by Risto Kankkunen (Risto.Kankkunen@Helsinki.FI).
- updated network drivers by Donald Becker
- updated serial drivers - tytso@Athena.mit.edu
- updated 387 emulation (Bill Metzenthen). The updated emulator code
has more exact trigonometric functions and improved exception
handling. It now behaves very much like a real 486, with only small
changes (greater accuracy, slightly different denormal NaN handling
etc - hard to detect the differences even if you are looking for
them).
- network timer fixes by Florian La Roche (much cleaned up net/inet/timer.c
and some bad race-conditions fixed).
- Scsi code updates by Eric Youngdale and others
- Sony CDU-31A CDROM driver by Corey Minyard added to the standard
kernel distribution.
- The Mitsumi CDROM driver is now part of the standard kernel. Driver
by Martin Harriss with patches by stud11@cc4.kuleuven.ac.be (yes, he
probably has a real name, but no, I haven't found it) and Jon Tombs.
- various other minor patches (preliminary ldt support etc)

PATCH: fork.c bug in 0.99.pl11
There is at least one known problem with 0.99pl11 - it's very minor and
will not lead to any real problems, but it's also very easy to fix,
so...
The problem is a one-liner oversight in kernel/fork.c (thanks to TjL for
noticing the symptoms - they aren't easy to see), which is fixed by the
following patch:
In fact, it's probably easiest to "apply" this patch by hand: just
change the "p->tss.fs = KERNEL_DS" in fork.c to "p->tss.fs = USER_DS"

[PATCH] Linux-0.99.11 (July 17, 1993)
Real file mmap with page sharing in the VM code. We don't do writable
shared mappings (and we won't do them for a _long_ time yet), but this
is a big step forward!
Note in the COPYING file that the GPL only covers the kernel, not user
programs. People were starting to find Linux more and more interesting..
Improved configure script.
Use nicer "save_flags()/cli()/restore_flags()" macros instead of
hardcoding the inline assembly. Clean up other inline assembly usage
too.
Trying to compile the kernel with C++ compiler. It will be a failed
experiment.
Original ChangeLog:
- The keyboard is dynamically changeable (this is true of pl10 as
well), and you need to get the "keytables.tar.z" archive to set the
keyboard to suit your taske unless you want to live with the default
US keymaps.
Use the "loadkeys map/xxx.map" command to load the keyboard map: you
can edit the maps to suit yourself if you can't find a suitable one.
The syntax of the keyboard maps should be obvious after looking at
the examples.
- The memory manager has been cleaned up substantially, and mmap()
works for MAP_PRIVATE. MAP_SHARED is still not supported for
anything else than /dev/mem, but even so it actually is usable for a
lot of applications. The shared library routines have been rewritten
to use mmap() instead of the old hardcoded behaviour.
- The kernel is now compiled with C++ instead of plain C. Very few
actual C++ features are used, but even so C++ allows for more
type-checking and type-safe linkage.
- The filesystem routines have been cleaned up for multiple block
sizes. None of the filesystems use it yet, but people are working on
it.
- named pipes and normal pipes should hopefully have the right select()
semantics in the presense/absense of writers.
- QIC-02 tape driver by Hennus Bergman
- selection patches in the default kernel
- fixed a bug in the pty code which led to busy waiting in some
circumstances instead of sleeping.
- Compressed SLIP support (Charles Hedrick). See net/inet/CONFIG
- the 'clear_bit()' function was changed to return the previous setting
of the bit instead of the old "error-code". This makes use of the
bit operations more logical.
- udelay() function for short delays (busy-waiting) added. Used
currently only by the QIC driver.
- fork() and sheduler changes to make task switches happen only from
kernel mode to kernel mode. Cleaner and more portable than the old
code which counted on being able to task-switch directly into user
mode.

[PATCH] Linux-0.99.10 (June 7, 1993)
People finally gave up on net-1, Ross Biro grew tired of the flames, and
net-2 appears with Fred van Kempen as maintainer. This is the big
switch-over version.
fsync() isn't just a stub any more, and System V IPC is also showing up.

Stub for iBCS2 emulation code.
[original announcement below]
I've finally released an official version of linux-0.99 patchlevel 10:
there have been various alpha versions floating around which differ in
details (notably networking code), which shouldn't be used any more.
The new linux version is available only as full source code: the diffs
would have been too big to be useful. You can find linux-0.99.10.tar.z
(along with keytables.tar.z) on nic.funet.fi: pub/OS/Linux/PEOPLE/Linus
and probably on tsx-11 and other linux archives within a day or two (so
check there first if you are in the states).
Linux-0.99 pl10 has a number of new features and changes in interface.
The most notable of these are:
- the networking code is reorganized (generally called "net-2",
although unrelated to the BSD release). The new code implements a
lot of standard features lacking in net-1, and also changes the user
interface to be closer to the BSD standards. Notably, the old
configuration binaries won't work, so to get the new networking to
work you'll have to get the net-2 binaries as well. The networking
binaries are available on tsx-11.mit.edu (and mirrors) under the
directory pub/linux/packages/net/net-2 (and the setup syntax has
changed somewhat..)
The networking code has been mainly organized and rewritten by Fred
van Kempen, with drivers by Donald Becker.
- serial line setup has been changed: linux 0.99 pl10 does *not* try to
autodetect serial ports very agressively. If you have other serial
ports than the standard com1/com2, or nonstandard IRQ etc values,
this means that it's less likely to work without any help. The
solution is not to recompile the kernel - you should get the
"setserial" program available from tsx-11.mit.edu in the directory
pub/linux/sources/sbin/setserial-2.01.tar.z that allows you to
dynamically configure your serial ports to suit your setup.
The main organizer behind the serial line changes is tytso (Theodore
Ts'o).
- Keyboard setup has changed: it is no longer hardcoded at compile
time, but instead you can use the new "loadkeys" program to load in a
new keyboard map on the fly. The default keyboard map is the normal
US keyboard (yes, I should have used the Finnish one by default, but
after thinking of all the problems that would have resulted in I
forgot about that idea). The loadkeys code can be found in the
"keytables.tar.z" archive, which also contains keymaps for most
normal keyboard types. To create a custom keyboard table is very
easy - just take a 5 minute look at the existing map files (they
resemble the ones used by xmodmap, so if you are familiar with
those..)
The loadable keymaps were mostly implemented by Risto Kankkunen.
There are a lot of other internal kernel changes, but they should be
mostly transparent, and noticeable only indirectly due to new features
or (hopefully) better/faster/whatever operation. These include:
- the SysV IPC patches are in by default: Krishna Balasubramanian.
If you need these, you know what it's about (notably, dosemu 0.49
wants them).
- inode handling is updated: inodes and files are now dynamically
allocated within the kernel, and use a hash table for faster lookup
(along with a NFU algorithm for the inode cache). Steven Tweedie.
- Updated FPU emulation: mostly exception handling changes, making the
emulator handle most exceptions the same way a 486 does. The
emulator is written by Bill Metzenthen.
- a few ext2-fs updates by Remy Card and Steven Tweedie.
- support for the 'fsync()' function (Steven Tweedie)
- various (minor) SCSI patches to catch some error conditions, add
support for VLB adaptec controllers without DMA and so on (different
people).
- other changes - I forget.
In addition to patches sent in by others, I've naturally made my own
changes (often *to* the patches sent in by others :-). Among other
things, the pl10 buffer cache code now also tries to share pages with
executables, resulting in better cacheing especially of binaries (giving
noticeable improvements in kernel recompilation speed on some machines).
Also, I've changed a lot of low-level things around to help the iBCS2
project: this includes things like internal segment handling and the
signal stack (which now looks the same as on SysV i386 unixes). All in
all, pl10 has a disturbing amount of new code, but will hopefully work
well despite (due to?) the number of changes.
The new networking code in particular will change the network setup a
lot - it now looks more standard, but if you were used to the old way of
doing things.. On the other hand, most people actively using the
networking features have hopefully gotten warnings about this on the NET
channel for the last few weeks. Also, the networking code still isn't
perfect: Fred is still working on it, but it seems to have reached a
reasonably stable platform on which it will be easier to build. Look
out for the new-and-improved networking manual, hopefully out soon(?).
Standard request: please try it all out, give it a real shakedown, and
send comments/bug-reports to the appropriate place (I'm always
appropriate, but you may want to send the report to the mailing lists
and/or the newsgroup as well). I apologize for the lateness of the
release (forcing hlu to make interim gcc releases that relied on
nonstandard kernels etc), and the changes are somewhat bigger than I'd
prefer, so the more testerts that try it out, the faster we can try to
fix any possible problems. The new kernel has gone through various
stages of ALPHA-diffs and some late ALPHA-pl10's, so there shouldn't be
any major surprises, but alpha releases tend not to get even close to
the coverage a real release gets...

[PATCH] Linux-0.99.9 (April 23, 1993)
Bill's math emulator now passes paranoia.
Last argument to ioctl is "long".
sys_clone() appears.
[original announcement below]
The latest kernel release is 0.99.9, and can be found on nic.funet.fi:
pub/OS/Linux/PEOPLE/Linus, both as patches relative to pl8 and as full
sources. The only major new feature is that the ST-0x driver has
finally been updated to the scatter-gather code: ST-0x users should with
luck get about 5 times the performance on disk-operations.. Seagate
code written by Drew Eckhardt.
0.99.9 also fixes:
- the FPU-emulator should now handle all rounding-modes correctly, and
pass all the paranoia package tests. Patches by Bill Metzenthen.
- bootup enhancements by Chrisoph Niemann (but the SVGA mode numbers
have changed, so you may have to edit your lilo configuration file
and/or the main Makefile to get the mode you normally want)
- ext2fs updated to the very latest release. Code by Remy Card and
Stephen Tweedie.
- various minor patches, some of them cosmetic, some of them fixes to
smaller bugs.. Thanks to everybody who sent them in (even though not
all made it)
