Change the ELF64_R_SYM() to shift 32 bits instead of 8 bits to match
binutils.
Ensure that three of the structures are the size that binutils writes
them. I just love code that doesn't share header files to avoid
problems like these.
Don't recognize a file as an a.out shared library unless it has at
least 2 version numbers. This fixes the bug where the dynamic
linker would try to load an ELF shared library if it found one.
Note, this change also fixes the same thing in "ld", because the
code is shared.
For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name. I haven't decided what, if anything, to
do about that.
Ignore the statically configured vfs type numbers and assign vfs
type numbers in vfs attach order (modulo incomplete reuse of old
numbers after vfs LKMs are unloaded). This requires reinitializing
the sysctl tree (or at least the vfs subtree) for vfs's that support
sysctls (currently only nfs). sysctl_order() already handled
reinitialization reasonably except it checked for annulled self
references in the wrong place.
Instantiate `nfs_mount_type' in a standard file so that it is present
when nfs is an LKM. Declare it in a header file. Don't forget to use
it in non-Lite2 code. Initialize it to -1 instead of to 0, since 0
will soon be the mount type number for the first vfs loaded.
Sysctl nodes are written to, so don't put them in the text section.
Our write protection of the kernel text on i386's doesn't actually
work in many cases:
- use of the 4MB page completely breaks it.
- CR0_WP isn't set until just before init is started, so the kernel
text is not write protected during kernel initialization.
Remove tcl from /usr/src, according to prior agreement. BTW, tcl-8.0 *is*
a port so there is nothing to be done on that side now.

>decision is, I'll respect it.
Another chance to architect people's principles...I can hardly wait. Seems
quite appropriate for a Sunday - I just need to get one of those collection
plates (and money envelopes) so I can profit, too. :-)
Tcl stays in /usr/src for now, but it needs to be kept up to date; same
for perl. If Jordan doesn't have "setup" (written in tcl) ready for 3.0,
then tcl will be yanked prior to the 3.0 release (and made into a port).
As for the ports tree only supporting the last FreeBSD release, this seems
sensible to me. The "ports" have always been a moving target between releases
and the problem is only going to get worse when we expand to supporting other
processor architectures. In any case, Satoshi is and always has been in charge
of the ports tree and whatever he wants to do with it (within reason :-)) is
his decision.
Does this cover the issue completely? I admit to deleting messages in this
thread with unusual fervor (people have FAR too much time on their hands!).
There's a fair bit of reasoning behind the above, but since everyone is sick
of arguing about this, I'll spare you the analysis.

Add OBJFORMAT to list of variables passed into /mk script since it seems
to think you're using aout otherwise (and emits a rather confusing and
inaccurate diagnostic about OBJFORMAT being set in /etc/make.conf when
it most demonstrably is not set there).
Explicitly pass the "-aout" option to ldconfig, until I've had a
chance to work out a better scheme to handle the separate
invocations necessary for a.out and ELF.
Implement ldconfig functionality for ELF. The hints are stored in
a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints".
These hints consist only of the directory search path. There is
no hash table as in the a.out hints, because ELF doesn't have to
search for the file with the highest minor version number. (It
doesn't have minor version numbers at all.)
A single run of ldconfig updates either the a.out hints or the ELF
hints, but not both. The set of hints to process is selected in
the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout"
or "-elf" command line option. The rationale is that you probably
want to search different directories for ELF than for a.out.
"ldconfig -r" is faked up to produce output like we are used to,
except that for ELF there are no minor version numbers. This should
enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports
even for ELF.
I implemented the ELF functionality in a new source file, with an
eye toward eliminating the a.out code entirely at some point in
the future.
Increase 'maxusers' to 32; with the number of people using GENERIC as
their one-size-fits-all kernel, this should help reduce the "out of foo"
reports.
Modify the xl_mediacheck() routine to also test for the case where the
XCVR value read from the EEPROM is completely wrong. I've had one report
of a 3c900 card that returns an xcvr value of 14, which is impossible
(the manual states that all vales above 8 are reserved). If the value
is out of the expe
Add PCI vendor ID for the 3c980-TX server adapter card, which apparently
also uses the cyclone chip. Graciously supplied Mats O Jansson
<maja@cntw.com>.
Also noted by Mats, the 10mpbs cyclone adapters should be named 3c900B,
not 3c905B. I haven't actually encountered a 10mbps only cyclone adapter
yet, nor anybody who has one, but this makes sense given the naming
scheme used for the older boomerang adapters.
o Enable standby mode in apm utility. You need a newer kernel for this
functionality to work (however, the kernel changes were committed
to current at 1998/07/05 23:29:11 PDT).
o Enable setting of a timer for later wakeup. Note, not all APM
BIOSes support this for all modes (mine doesn't support waking up on
a timer from standby mode).
o Print out the APM capabilities, as reported by the BIOS.
o Report wake on ring indication. No way to enable/disable this, but
it is reported.
o update man page with above
o The output of this command has changed, so if you have a script that
parses its output, then you may need to rewrite it slightly.
o The code attempts to deal with older kernels than July 5, 1998, but
that part of the code isn't well tested.
Generic plug-and-play enumerator infrastructure. Query supplied
enumerators, crossreference returned identifiers with a text-format
database and automatically load corresponding modules and dependancies.
-current commit for st.c, kernel support for /bin/mt's 'comp' option.
(tested with exabyte and DAT tape units. Does not apparently work with
all SCSI tape's, though).
- Move some startup code from MD to MI sections
- Add a 'copyout' and some copyout-related functions. These will be
obsoleted when BTX is available for the 386 and the kernel load
area becomes directly addressable.
- Add the ability load an arbitrary file as a module, associating
and arbitrary type string with it. This can be used eg. for loading
splash-screen images etc.
- Add KLD module dependancy infrastructure. We know how to look for
dependancies inside KLD modules, how to resolve these dependancies
and what to do if things go wrong. Only works for a.out at the
moment, due to lack of an MI ELF loader. Attach KLD module information
to loaded modules as metadata, but don't pass it to the kernel (it
can find it itself).
- Load a.out KLD modules on a page boundary. Only pad the a.out BSS
for the kernel, as it may want to throw symbols away. (We might want
to do this for KLD modules too.)
- Allow commands to be hidden from the '?' display, to avoid cluttering
it with things like 'echo'. Add 'echo'.
- Bring the 'prompt' command into line with the parser syntax.
- Fix the verbose 'ls'; it was using an uninitialised stack variable.
- Add a '-v' flag to 'lsmod' to have it display module metadata as well
(not terribly useful for the average user)
- Support a 'module searchpath' for required modules.
- The bootstrap file on i386 is now called 'loader' to permit the
/boot directory to use that name.
- Discard the old i386 pread() function, as it's replaced by
arch_readin()
