1. stepping over syscalls (gdb ni) sends you to DDB, and returned
to the wrong address afterwards, with or without DDB. patch in
i386/i386/trap.c below.
2. the linux emulator (modload'ed) still causes panics with DIAGNOSTIC,
re-applied a patch posted to one of the lists...
for testing.. (for cdevsw_add and bdevsw_add)
make the lkm code use the new generic devsw add routines (if so required)
define these routines in conf.h so we can use them
This is really just a token gesture at this point. We can't really turn
on swapping here anymore because (I think) we need to do a namei() lookup
in order to get a vnode which we can pass to swaponvp(). But to do a
namei(), we need a properly initialized proc structure, and we don't
have one. (I was hopping to toss it proc0, but that isn't initialized
until later.) We could conceiveably fabricate a dummy proc structure
to make namei() happy, but that's too much work for too little payoff.
For now, swapgeneric's only remaining saving grace is that it lets
you set the root device with -a.
This is a place for all things to do with conf.c and conf.h
that are not machine specific.
Other things that are at present in i386/isa/conf.c might
migrate into here..
It's the first small step in cleaning up the device interface
to make it more dynamic and to assist in more modular drivers
(i.e. both loadable via LKMs and linked in..
e.g able to add a device without having to edit conf.c)
this code is not yet used and the whole thing will be conditionally
compiled in for a while till proven useful :)
matching IP options..Check and test this - i made only a couple
of rough tests and this could be buggy.. Ipaccounting can't use
IP Options (and i don't see any need to cound packets with specific
options either..)
More to come...
1542 revs work by assuming the next few sequential ID codes are
new Adaptec boards and enabling them after printing a warning.
Conditionalize the informational boot messages with "if (bootverbose)".
1) "obj" was't initialized properly, resulting in an important vm_page_lookup
always failing (resulting in a panic).
2) busy pages could be put on the cache queue or freed (resulting in a panic).
were making and were no-brainers. However, the xcdplayer
eject button didn't work because xcdplayer gave up and didn't bother
to try the EJECT ioctl anyway when CDIOCALLOW was not available.
This all works now.
o A change so that xcdplayer gets TOC entry data for the lead-out area
on the disc. Xcdplayer can now play the last track on a CD, which
it would not do in earlier versions (but no one reported).
Cdplayer gets the TOC data differently and it works in old and new
versions.
o Eliminated a race condition that caused the driver to sleep forever
on very slow and heavily loaded systems on rare occasions when
the system was doing lots of audio-related ioctls to the drive.
o Fixed a problem where a locked drive could be unlocked by accessing
one of the non-locking devs. Door locking now follows the documented
rules.
o Made all wait channel strings unique to matcd.

scheduled for demolition. This is a first step: get rid of if_zereg.h,
by adding the five extra definitions to if_edreg.h.
Also add some definitions which will become needed when if_ze.c gets
replaced entirely by pccard and if_ed.c. (this is a 2.1.0 candidate)
is swapped in. Also, remove unnecessary map locking/unlocking during
selection of processes to be swapped out.
This code might afford proper panics as opposed to spontaneous reboots
on certain systems. This should allow us to debug these problems better.
David Greenman, it has been determined that the more sophisticated code
only made a very minor difference in fault performance. Therefore, this
code eliminates some of the complication of the fault code, decreasing
the amount of CPU used to scan shadow chains.
support for EXT2FS. Note that the Sig-11 problems appear to be caused by
this, but there is still probably an underlying VM problem that let this
clustering bug cause vnode objects to appear to be corrupted.
The direct manifestation of this bug would have been severely mis-read
files. It is possible that processes would Sig-11 on very damaged
input files and might explain the mysterious differences in system
behaviour when phk's malloc is being used.
with the driver's stability now. I've not had a single problem with it for
weeks.. All that remains is a bit of performance tuning, and finishing
the manpages.
Fix loopback and discard interfaces to understand BPF writes.
(These two from Bill Fenner to fix PR 512.)
Move ifpromisc() from bpf.c to if.c as suggested by comment in BPF.
Send a notice to the log when promiscuous mode is enabled.
time ago. I left in Garrett's one, because his was in the 4.4-Lite-2
location, making any diffs just that little bit smaller.
I presume this choice means that netstat needs to be recompiled before
"netstat -s" will give a meaningful answer on tcp stats.
