it is both uneeded and breaks certain lock-step timing in the rexec
protocol.
Yes, an attacker can "relay" connections using this trick, but a properly
configured firewall that would make this sort of subterfuge necessary in the
first place (instead of direct packet spoofing) would also thwart useful
attacks based on this.
SCBs in response to a busfree.
When re-queueing an SCB that returned with QUEUE FULL status, reset its timeout.
Ensure that aborted SCBs have an error code set in there xs before it gets
passed back up with scsi_done.
Fix a few KNF nits.
Immediate SCBs, since they always send messages that tell the target to
transition to bus free now rely on the busfree interrupt instead of the
IMMEDDONE sequencer interrupt that was generated before.
Rearrange some code in the message out loop to give ATN a little more time
to drop before we ACK the last byte.
Use SPIORDY instead of REQINIT when snooping for a tag message on a reconnect.
This is done for the same reasons we use SPIORDY in the inb functions.
When going into BITBUCKET mode, turn off HDMAEN in the DFCNTRL register so
that we can "not care" what the value of HCNT is. If HCNT is 0, BITBUCKET
mode won't transfer any data if HDMAEN is set. Seeing as we don't want the
transfer to even think about touching the host, this seems more sane anyway.
Thanks to "Dan Willis" <dan@plutotech.com> for pointing out that this was
a problem.
uses /usr/include/sys/*, which may point to a different build tree. I'm
not sure that this is necessary, but there was a question mark over what
/usr/include/sys points to when building the "user mode" binaries in the
kernel code, especially when building the smp tree.
I suspect that the "right" line here is to use ${INCLUDES}, but that
causes warnings about unused static inline functions in stdio.h and ctype.h
- Don't link against libkvm and don't uselessly include <kvm.h>.
- Declare constant objects as const.
- Declare functions with the correct types.
- Call functions with the correct parameters.
Not fixed:
- The sysctl parsing remains ugly (but it may be the best we can do).
- atnetrange() should use strtoul() rather than sscanf() for better
error checking.
also fixes a bug I've been chasing for a LONG TIME,
due to the fact that spec_bwrite is a NOP and I didn't realise it..
old symptom:
mount -t devfs devfs /mnt
mount /mnt/wd0e /mnt/mnt2
umount /mnt2 <process hangs>
there are some pretty large structural differences internal to devfs
but outwards it should look the same.
I have not yet tested extensively but will do so and fix 3 warnings tomorrow.
SPIORDY should go active on any REQ of the bus, so testing for REQINIT is
not necessary. It also seems that testing for SPIORDY is more robust then
REQINIT since SPIORDY comes active after REQINIT and PHASEMIS seems to take
some time to come true after REQ is asserted if the phase has changed. Of
course, none of this is documented.
This should give the code savings of my original changes, without breaking the
driver on fast peripherals.
Fenner was kind enough to point out the error of my ways. This incorporates
diffs from him which:
- Keep everything in network order.
- Log the booted ether & ip address, instead of my address on that net
- change several exit()'s to return()'s, so that rarpd continues running
even if it thinks it's in a weird state.
One small tweak by me: in rarp_bootable(), we have to make sure to
construct 'ipname' in host byte order (if we don't, we have to
specify /tftpboot/<remote IP in hex> with <remote IP in hex> in
network byte order, which is confusing).
Also restored use of <dirent.h> rather than <sys/dir.h> as pointed
out by bde.
Also updated the man page so that the -v flag is documented.
With any luck, I won't have to touch this thing again.
now identical with the distributed versions, which may cause some
abbreviations to change for people in obscure zones. (The abbreviations
can be changed again if need be.) It also changes the abbreviation
of Central European Time to `CET' from its previous value of `MET'
(a curious German-English hybrid). Finally, we have finally rid
ourselves of those nasty ZONE-DESCR comments, which were a maintenance
nightmare, in favor of the new zone.tab file. We are not using the
distribution's iso3166.tab file because we have our own list.

- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results
were just confusing most of the time.
- The program no longer contains a pre-compiled list of timezones
(compiled by groveling through the tzdata source files for comments
starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file
supplied with current versions of the timezone data files, to determine
the list at run time. (It also requires the ISO 3166 table I
committed some months ago.)
AS A RESULT, this program will NOT work until the new timezone data files
are committed (should happen sometime soon).

The 'getchar' function in syscons (sccngetc) is used by UserConfig to
get keyboard input from the user. When it was modified to use the
shared keyboard port routines it used the port passed in during the
probe routine. Since the probe routine was not yet called, the port was
set to 0, which is obviously not going to work.
Pre-initialize sc_port to IO_KBD which is really a kludge, but it's how
the previous driver did it's job.

Some cosmetic tweaks.
Some improvement in translation.
This change, together with recent change to jmembers.sgml and jcontrib.sgml,
should definitely go into 2.2.
