pkg_version.pl now understands the new package/port numbering scheme
introduced by version 1.349 of ports/Mk/bsd.port.mk and originally
submitted by kris.
In particular, it understands the $PORTREVISION (FreeBSD-specific changes
or patches to a port) and $PORTEPOCH (for re-sorting version numbers
when not used or when broken).
Upon reflection, I decided that bootfile must have priority over kernel
as the kernel name. The one very unfortunate consequence is that kernel
as an absolute path loses the priority. It will only be tried after
/boot/${kernel}/${bootfile}. I'll see what can be done about it later.
add attrbute(packed) to union def with specific align constraitn.
move file static variable to auto variable, make in6_cksum() work better in
kernel-MP environment. sync with kame.
Add stat, uptime and version.
Note that version currently returns the first line of the version string
from vers.c, which is not quite what a Linux system would return.
First tackle at trying to handle the New Deal on kernels.
Load the first of the following kernels to be found:
${kernel} if ${kernel} is an absolute path
/boot/${kernel}/${kernel}
/boot/${kernel}/${bootfile}
${kernel}/${kernel}
${kernel}/${bootfile}
${kernel}
${bootfile}
The last instance of ${kernel} and ${bootfile} will be treated as a
list of semicolon separated file names, and each will be tried in turn,
from left to right.
Also, for each filename loader(8) will try filename, filename.ko,
filename.gz, filename.ko.gz, in that order, but that's not related
to this code.
This resulted in a major reorganization of the code, and much of what
was accumulating on loader.4th was rightly transfered to support.4th.
The semantics of boot-conf and boot also changed. Both will try to load
a kernel the same as above.
After a kernel was loaded, the variable module_path may get changed. Such
change will happen if the kernel was found with a directory prefix. In
that case, the module path will be set to ${directory};${module_path}.
Next, the modules are loaded as usual.
This is intended so kernel="xyzzy" in /boot/loader.conf will load
/boot/xyzzy/kernel.ko, load system modules from /boot/xyzzy/, and
load third party modules from /boot/modules or /modules. If that doesn't
work, it's a bug.
Also, fix a breakage of "boot" which was recently introduced. Boot without
any arguments would fail. No longer. Also, boot will only unload/reload
if the first argument is a path. If no argument exists or the first
argument is a flag, boot will use whatever is already loaded. I hope this
is POLA. That behavior is markedly different from that of boot-conf, which
will always unload/reload.
The semantics introduced here are experimental. Even if the code works,
we might decide this is not the prefered behavior. If you feel so, send
your feedback. (Yeah, this belongs in a HEADS UP or something, but I've
been working for the past 16 hours on this stuff, so gimme a break.)

Rename mtx_enter(), mtx_try_enter(), and mtx_exit() and wrap them with cpp
macros that expand to pass filename and line number information. This is
necessary since we're using inline functions instead of macros now.
Add const to the filename pointers passed througout the mtx and witness
code.

Now boot-conf can also receive parameters to be passed to the kernel
being booted. The syntax is the same as in the boot command, so one
boots /kernel.OLD in single-user mode by typing:
boot-conf /kernel.OLD -s instead of
boot-conf -s /kernel.OLD
The syntax still supports use of directory instead of file name, so
boot-conf kernel.OLD -s
may be used to boot /boot/kernel.OLD/kernel.ko in single-user mode.
Notice that if one passes a flag to boot-conf, it will override the
flags set in .conf files, but only for that invocation. If the user
aborts the countdown and tries again without passing any flags, the
flags set in .conf files will be used.
Some factorization was done in the process of enhancing boot-conf,
as it has been growing steadly as features are getting added, becoming
too big for a Forth word. It still could do with more factorization,
as a matter of fact.
Override the builtin "boot" with something based on boot-conf. It will
behave exactly like boot-conf, but booting directly instead of going
through autoboot.
Since we are now pairing kernel and module set in the same directory,
this change to boot makes sense.
Strictly speaking, this works. It enumarates the PnP devices, and
load the modules needed according to a file relating module names
(actually, _file_ names, not really modules -- the dependency
stuff is not exported to loader's UI) to PnP IDs.
But it still lacks a number of desired features, and it's too crude
for my tastes. But since I don't have time to work on it, it might
be preferable to make it available to those who might. It's not
installed by default, much less loaded. In fact, it wouldn't even
had a copyright message (who? me? assume responsibility for _this_?),
if the cvs commit hadn't aborted for lack of $FreeBSD$, and I decided
to just cut&paste the stuff from elsewhere.
Add the infrastructure necessary to handle PnP from a Forth script.
Also, export the file_findfile() function. Again, this is taken from
work in progress but frozen for the time being. Since it works, I'd
rather commit and remove any uglyness later than hide it on my tree.
Add constructors to crude structure support. Rework some of the
code into a more modular interface, with hidden vocabularies and
such. Remove the need to a lot of ugly initialization.
Also, add a few structure definitions, from stuff used on the C
part of loader. Some of this will disappear, and the crude structure
support will most likely be replaced by full-blown OOP support
already present on FICL, but not installed by default. But it was
getting increasingly inconvenient to keep this separate on my tree,
and I already lost lots of work once because of the hurdles, so
commit this.
Anyway, it makes support.4th more structured, and I'm not proceeding
with the work on it any time soon, unfortunately.
Fix autoboot. Now autoboot *always* show the correct kernel name. It
gets the name from the environment variable kernelname, which is set
when a kernel is loaded. For this reason, autoboot will _first_ try
to load a kernel, and only proceed with the wait prompt after that
succeeds. If it fails, it will abort immediately.
While I understand some may think this behavior undesirable, I think
it is, overall, the best thing to do, even if we do not consider the
aesthetic issue. Notice that anyone using the default loader.rc
already has the kernel loaded before autoboot.
On unload, unset kernelname.
Separate the code that tries to load a kernel from the list of options
to the function loadakernel(). It is used by both boot() and
autoboot().

Back out my previous commit as well as some SMPng changes to revert the
siosetwater() function to its previous behavior of always disabling
interrupts and obtaining the com_lock before returning.
Disallow '/' characters in LC_* environment variables which might
be used to point to a bad locale file. This is only believed to be a
minor security risk - the only risk is if some program uses the result
of a localized string as a format specifier in a vulnerable function
like sprintf(). No such code is believed to exist in the FreeBSD base
system, although it is possible that badly written third party code
would do that.

Add a mild warning for people to expect problems in -current after the
SMPng merge. Suggest 4.x-stable for a while for those people that are
unable or unwilling to cope with problems.
After 6 hours of use tonight, my gut tells me that we're going to have
lots of problems crop up in the coming weeks.

Look for libstand in the built tree rather than in /usr/lib. This
likely could be done better, but the tree is broken and I wanted to
get a fix into the tree.

Special-case the LED twiddling code so that it doesn't do anything
on the NEC VersaPro NoteBook PC. This 21143 implementation has no LEDs,
and flipping the LED control bits somehow stops it from establishing
a link. We check the subsystem ID and don't flip the LED control
bits for the NEC NIC.
Pierre Beyssac originally derived linprocfs from procfs, and I've made (and
will keep making) significant modifications, so I'm adding both our copyrights
to the top of these files.
The kernel is now known as `kernel.ko' and it and its matching modules
live in ``/boot/kernel/''. So tweak the release build to match previous
assumptions and expectations.
