9b3e7ec49d Latest fixes from Serge:
I tried to solve the problem of IDE probing compatibility in this version.
When compiled without an ATAPI option, the wd driver is
fully backward compatible with 2.0.5.  With ATAPI option,
the wdprobe becomes strictly weaker.  That is, if wdprobe works
without ATAPI option, it will always work with it too.

Another problem was with the CD-ROM drive attached as a slave
in the IDE bus, where there is no master.  All IDE CD-ROM
drives are shipped in slave configuration, and most users
just plug them in, never thinking about jumpers.
It works fine with ms-dos and ms-windows, and this
version of the driver supports it as well.

The eject op can now load disks.  Just repeat it twice,
and the disk will be ejected and then loaded back.

The disc cannot be ejected if it is mounted.

e8f9a07320 Fix the support for MANSRC (it was broken by the compression changes):
use .PATH.n to get the dependencies right and to avoid some shell tests.

Remove bogus dependency of individual compressed man pages on MANDEPEND.

Use for loops to avoid duplicated code.

Combine some rm steps in installation of links.  Linking still takes too
long.

cb759a257f Don't allow mmapping of physical page 6 (ENXIO).
nxmmap() returned a bogus value as well as having a bogus type.  Some
drivers use nxmmap() for configured devices (`nx' functions should
only be used for unconfigured devices).  These drivers allowed mmapping
physical page 6, which may have interesting contents.  vm has kludges
to avoid the same bug with nullop() returning page 0 and enodev()
returning page 19 (ENODEV), but didn't handle enxio() returning page 6.
vm is the wrong place to handle these bugs.

91badc866f Routes can be asymmetric. Always offer to /accept/ an MSS of up to the
capacity of the link, even if the route's MTU indicates that we cannot
send that much in their direction.  (This might actually make it possible
to test Path MTU discovery in a useful variety of cases.)

e2d4b1f051 Reduce jitter of Pentium microtime() implementation by letting the counter
free-run and doing a subtract in microtime() rather than resetting the
counter to zero at every clock tick.  In combination with the changes to
kern_clock.c, this should eliminate all the immediately obvious sources
of systematic jitter in timekeeping on Pentium machines.

3abc79d2ee The additional checks involving sequence numbers in MTU discovery resends
turned out not to be necessary; simply watching for MTU decreases (which
we already did) automagically eliminates all the cases we were trying to

3948edc24c Another tweak/speedup pass:
- Fix buffer overflow problem once and for all: do away with the buffer
  copies to 'user' prior to calling _scancaches() and just pass a pointer
  to the buffer returned by yp_match()/yp_first()/yp_next()/whatever.
  (We turn the first ':' to a NUL first so strcmp() works, then change it
  back later. Submitted by Bill Fenner <fenner@parc.xerox.com> and
  tweaked slightly by me.

- Give _pw_breakout_yp() the 'more elegant solution' I promised way back when.
  Eliminate several copies to static buffers and replace them with just
  one copy. (The buffer returned by the NIS functions is at most
  YPMAXRECORD bytes long, so we should only need one static buffer of
  the same length (plus 2 for paranoia's sake).)

- Also in _pw_breakout_yp(): always set pw.pw_passwd to the username
  obtained via NIS regardless of what pw_fields says: usernames cannot
  be overridden so we have no choice but to use the name returned by
  NIS.

- _Again_ in _pw_breakout_yp(): before doing anything else, check that
  the first character of the NIS-returned buffer is not a '+' or '-'.
  If it is, drop the entry. (#define EXTRA_PARANOIA 1 :)

- Probe for the master.passwd.* maps once during __initdb() instead
  of doing it each time _getyppass() or _nextyppass() is called.

- Don't copy the NIS data buffers to static memory in _getyppass()
  and _nextyppass(): this is done in _pw_breakout_yp() now.

- Test against phkmalloc and phkmalloc/2 (TNG!) to make sure we're
  free()ing the yp buffers sanely.

- Put _havemaster(), _getyppass() and nextyppass() prototypes under
  #ifdef YP. (Somehow they ended up on the wrong side of the #endif.)

- Remove unused variable ___yp_only.

36b2e7c238 A one-liner:
We already check for (and reject entries with) '+' or '-' as the first
character of the key side of the key/data pair; we should check the data
side too. (Letting spurious +/- entries into the NIS maps is bad karma.)

middle of a fully-open window.  Also, keep track of how many retransmits

necessary, but it's an unusual condition...
