diff output, and replace them with "(password)". The diffs get
mailed to root, which in many cases is forwarded across the
Internet. A patient sniffer could acquire the entire "master.passwd"
file by saving all the diffs. With this fix, you still see that the
password changed, but you don't see the details.
Unless somebody talks me out of it, I am going to merge this into -2.2
in 48 hours.
from last time. Some people have pointed out that there were some odd
side-effects in the changes I made. Two things are different:
- sc_print_addr() will print 'foodev0:' (i.e. sd0:, st0:, cd0:, etc...)
if the device name is known. If it's not known, it'll use a longer
notation. This shortens error messages back to a sane length.
- Added a small function called sc_print_init() to set the sc_printing
flag so that sc_print_addr() will know that we want it to print a
linefeed. Used this in scsi_device_attach() to restore proper carriage
return printing behavior which I broke.
Remaining bogons: the NCR SCSI driver prints out information while the
device-specific attach routine is running with its own linefeeds. This
breaks up the individual messages emitted by the subdriver modules and
causes at least one message to appear on a line by itself without a
device spec prefix. I'm not sure of the correct way to fix this, and
I don't have any NCR SCSI hardware to test with anyway.
There's probably more, but I gather that a rewrite of the SCSI subsystem
is pending anyway, so I'll leave the rest to Those Who Know More About
This Than I (tm).

Add '-a' audible flag, so terminal will beep upon receipt of a reply
packet. Useful for debugging ethernet runs, among other things.

Patch attached. The ellipsis causes gcc to flag this as a varargs function,
and the name "__builtin_va_alist" is special cased in gcc to hide the last
argument in the arglist.

The PS/2 mouse device responds to a reset command with a sequence of
ACK(fa), RESULT(aa) and ID(00). Most PS/2 mice immediately returns
ACK, but spend sometime before sending RESULT. The Armada takes time
before ACK; extra delay is necessary before the call to read ACK.
The problem was reported in comp.unix.bsd.freebsd.misc and the patch
was tested by the reporter. No PR was filed, by the way.
read-mode access to CD-ROM media in the worm(4) driver. No whistles
and bells yet, like all the CDIO* commands, but at least a start.
In order to do this, i had to slightly rearrange the semantics of an
open(2) on the worm driver: now, opening it with O_NONBLOCK set means
no actual IO operations will be intended but only ioctls are to be
processed. This mode is used by wormcontrol(8) to prepare a track
and/or session.
I have only been able to test this on a 2.2-GAMMA system by now, and
only the !DEVFS part is tested yet. Also, i have only done a dummy
burn so far, but wouldn't expect many surprises else. Report bugs to
me ASAP, if there's reasonable demand and i hear no objections, i
might consider merging it into the 2.2 branch as well.
everything that depends on this needs to be doc as well. Maybe they
doc tools should be split out into a separate distribution, but until
that decision is made, at least keep them together.
