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.
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.
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.
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.
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().

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.

* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The
alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be
preempted (i386 only).

Introduce a new sysctl node:
net.inet.accf
Although acceptfilters need refcounting to be properly (safely) unloaded
as a temporary hack allow them to be unloaded if the sysctl
net.inet.accf.unloadable is set, this is really for developers who want
to work on thier own filters.
A near complete re-write of the accf_http filter:
1) Parse check if the request is HTTP/1.0 or HTTP/1.1 if not dump
to the application.
Because of the performance implications of this there is a sysctl
'net.inet.accf.http.parsehttpversion' that when set to non-zero
parses the HTTP version.
The default is to parse the version.
2) Check if a socket has filled and dump to the listener
3) optimize the way that mbuf boundries are handled using some voodoo
4) even though you'd expect accept filters to only be used on TCP
connections that don't use m_nextpkt I've fixed the accept filter
for socket connections that use this.
This rewrite of accf_http should allow someone to use them and maintain
full HTTP compliance as long as net.inet.accf.http.parsehttpversion is
set.
