- check return call of several important system calls
- clean up some more cruft.
- support "rexecd -l" for extra (syslog(3)) logging.
- avoid *sprintf
1) Quirk entries for Storage Tek 9490 (Timberline) and D3 (Redwood)
drives.
2) Modification to st_loadtape to do a REWIND to BOT if the
action is a load and the tape doesn't support the LOAD command
(9490, SD3, and IBM 3590).
3) Cleaned up the 'undersized user record' error message to
make a little more sense.
Various bug fixes:
kern/1275: Now returns values in dsreg and erreg and sets resid
(as best as it can for a 16 but integer). See also
a recent change to mtio.h. We are declining to fix
the portion of this bug about naming a more specific
SCSI device. Since there is nothing programmatic
you can do with that information, it is not useful
to pass back at this time.
A side effect of this change is that doing MTIOCGET
also forces a mode sense (to get the current state
of WRITE PROTECT).
kern/5647: Now no longer logs to the console ILI or Filemark or (first)
EOM (on write) errors (unless SCSIDEBUG is set).
kern/5525: Substantially increased timeouts for a variety of
operations, and split them into categories of
I/O, Space, and Control operations (each have
likely different inherent times). I/O is for
reads/writes. Control is for mode sense/select.
Space is for spacing the tape.
Until EOM handling is changed, though kern/391 is still not fixed. A side
effect of EOM handling is that you now always 'lose' (to the writing
application's view) the last write since EIO is what is returned on
EOM detection during writes. Hopefully the reader applications don't
get too bent out of shape by this.
now be inserted into the kernel for a self-contained installation kernel.
No more questions or problems trying to copy the miniroot to the swap
partition.
tape driver. Basically, we'll report what we can for resid, dsreg will
reflect RDONLY and MOUNTED, and erreg will retain the last seen Sense Key.
An MTIOCGET will clear these.
takes to do IELEM can be proportional to the number of elements, but is
also affected by wierd things like how readable the barcodes on the
media are. There are worst case scenarios I've seen where there are
white labels on the back of tapes with pencilled in labels which is
*just* close enough to being a bar code that an Exabyte 120 would
peer at them myopically and long enough for a *really* long time to
pass in inventorying the jukebox.
I've upped the limit to be proportional to 5 minutes per element. That
is long enough that someone I'm sure will complain about "you wait
to long and should time out" for broken h/w.
As is also noted in the PR, there are a lot of other issues here. It's
really also a question as to whether to update this driver or go
with CAM's driver. This one doesn't have switching between block
descriptors and not, doesn't support volume tag setting, and so on.
Time is limited. This PR should have been closed and fixed right away,
tho.
- check return call of several important system calls
- clean up some more cruft.
- support "uucpd -l" for extra (syslog(3)) logging.
- add a man page for uucpd. did it really arrive in 4.2BSD as the code
indicates? that's what `HISTORY' says...
check at 3 second intervals if any are left.
This will help slow machines to cleanly shut down X servers (to make the
console visible), databases, or Usenet news servers.
- KNF
- ensure hostname has trailling nul.
- use initgroups/setgid/setuid rather than just setuid, and do this earlier.
- find "from:" and "subject:" as well.
- use strvis(3) rather than some local crufty code.
