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.

f7faedb40d Restore initialization of %ecx for the !I586_CPU case.
Don't declare _i586_ctr_bias.  The usual style, which was
followed in microtime.s, is to omit extern declarations.

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
protect against.

a2029046fd Add a command-line option `-I' to disable logging from UDP.
Document `-d' and `-I'.  Add a BUGS section noting that
logging from UDP is an unauthenticated remote disk-filling service,
and probably should be disabled by default in the absence of some sort
of authentication.

sometime around 1.51, the check for minphys dissappeared out of

we weren't hecking that the adapter could handle a transfer of

this explains the rash of failures I've seen reported recently
with "too many DMA segments" on raw devices

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.)

143d7a5499 More MTU discovery: avoid over-retransmission if route changes in the
middle of a fully-open window.  Also, keep track of how many retransmits
we do as a result of MTU discovery.  This may actually do more work than
necessary, but it's an unusual condition...

1448ea7e81 Change alternate space base name from /emul/ibcs2 to /compat/ibcs2,
in line with linux alt space of /compat/linux.
This was pointed out by Stefan Esser.

In cheching alt space for libraries in imgact_coff.c, use const
ibcs2_emul_path instead of its own local string.  Also do a proper
malloc of temp name according to MAXPATHLEN.

9e03db613c Remove old files no longer needed.
Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code.  The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

 o  "clean" code, including strict prototyping.
 o  Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls.  Generation includes system tables, structure definitions,
and prototyping of function calls.
 o  ibcs2 emulator does not rely on any COMPAT_43 system calls.
 o  embedded socksys support
 o  ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
 o  alternate /emul/ibcs2 namespace searched first for files in ibcs2
system.  Usefull to keep sysv libraries, binaries in /emul/ibcs2.
 o  many other finer details and functions fixed or implemented.
