943c18018b Fix standards conformance bugs in <signal.h>:
include/signal.h:
There was massive namespace pollution from including <sys/types.h>.
POSIX functions were declared even when _ANSI_SOURCE is defined.

sys.sys/signal.h:
NSIG was declared even if _ANSI_SOURCE or _POSIX_SOURCE is defined.
sig_atomic_t wasn't declared if _POSIX_SOURCE is defined.
Declare a typedef for signal handling functions and use it to
unobfuscate declarations and to avoid half-baked function types
that cause unwanted compiler warnings at certain warning levels.
Fix confusing comment about SA_RESTART.

sys/i386/include/signal.h:
This has to be included to get the declaration of sig_atomic_t even
when _ANSI_SOURCE is defined, so be more careful about polluting
the ANSI namespace.

Uniformize idempotency ifdefs.

200db83402 Use the new machine-dependent definitions of _BSD_OFF_T_ and

e9c2b07f51 Define macros _BSD_OFF_T_ and _BSD_PID_T_ suitable for use instead
of the typedefs off_t and pid_t when use of the latter would cause
namespace pollution.  These macros are used like _BSD_VA_LIST_ and
aren't #undef'ed when the corresponding typedef is declared.
off_t is very machine-dependent and should never have been decided
in <sys/types.h> (its declaration is compiler-dependent).  pid_t
isn't very machine-dependent, but this might change.  `long' is
a wasteful type for it if longs are longer than ints.

Move the definition of _BSD_VA_LIST_ away from the comment that
suggests that it is #undefed when va_list is declared.

6acceb40dc Pass the correct nonblocking flag to VOP_CLOSE() in vclean().
VOP_CLOSE() takes `F' (file) flags, not `IO' flags.  At least that's
what close() passes.  I previously fixed ttylclose() to check
FNONBLOCK instead of IO_NDELAY.  This broke the call from vclean()
and cleaning of ptys sometimes deadlocked.

a62dc40654 Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount).  The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server.  It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs.  Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

82aaeb09ad Change ld.so to correctly load dependant libraries for dlopen and unload them
on dlclose.  Also correctly call constructors and destructors for libraries
linked with /usr/lib/c++rt0.o.
Change interpretation of dlopen manpage to call _init() rather than init()
for dlopened objects.
Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to
call destructors when an object is unloaded.
Change interface between crt0 and ld.so to allow crt0 to call a function on
exit to call destructors for shared libraries explicitly.

These changes are backwards compatible.  Old binaries will work with the new
ld.so and new binaries will work with the old ld.so.  A version number has
been introduced in the crt0-ld.so interface to allow for future changes.

6c0828a6c6 Do the same sanity checking in _pw_breakout_yp() that we do in
_gr_breakout_yp(): if we encounter a NULL pointer generated as the
result of a badly formatted NIS passwd entry (e.g. missing fields),
we punt and return an error code, thereby silently skipping the
bad entry.

e0ee807b3d Fix for a potential problem reported by a user I bumped into on IRC
last night:

_gr_breakout_yp() doesn't check for badly formatted NIS group entries.
For example, a bogus entry like this:

bootp::user1,user2,user3

will lead to a null pointer dereference and a SEGV (note that the GID
field is missing -- this results in one of the strsep(&result, ":")
returning NULL). The symtpom of this problem is programs dumping
core left and right the moment you add a + entry to /etc/group.
Note that while this is similar to an earlier bug, it's caused by a
different set of circumstances.

The fix is to check for the NULL pointers and have _gr_breakout_yp()
punt and return a failure code if it catches one. This is more or
less the behavior of SunOS: if a bad NIS group entry is encountered,
it's silently ignored. I don't think our standard (non-NIS) group
parsing code behaves the same way. It doesn't crash though, so I'm
citing the 'it ain't broken, don't fix it' rule and leaving it alone.

I'll probably have to add similar checks to _pw_breakout_yp() in
getpwent.c to ward off the same problems. It's rare that bad NIS
map entries like this occur, but we should handle them gracefully
when they do.

when syscons stops mapping the console to minor MAXCONS.  There is
usually no corresponding device in /dev, and the correct device has
minor 0.

77370fd9ed Use
ftp://ftp.freebsd.org/pub/FreeBSD/distfiles/

as our distribution point for distfiles and patches.  Other than
cosmetic changes (freebsd.cdrom.com -> ftp.freebsd.org), the
omission of "ports" is important.  I would like to move this
directory completely out of the ports tree (on the ftp site),
so that people who do "get ports.tar.gz" won't get a bogus distfiles
-> ../distfiles symlink (which will make "make fetch" fail).

Sometime around the 2.1 release, the distfiles link will be deleted.

d1e00e9390 Improve the handling of large minor numbers:
cpio/copyout.c:
Don't output a file if the major, minor or totality of its rdev would be
truncated.  Print a message about the skipped files to stderr but don't
report the error in the exit status.  cpio's abysmal error handling doesn't
allow continuing after an error, and the rdev checks had to be misplaced
to avoid the problem of returning an error code from routines that return
void.

pax/pax.h:
Use the system macros for major(), minor() and makedev().

pax already checks _all_ output conversions for overflow.  This has the
undesirable effect that failure to convert relatively useless fields
such as st_dev for regular files causes files not to be output.  pax
doesn't report exactly which fields couldn't be converted.

tar/create.c:
Don't output a file if the major or minor its rdev would be truncated.
Print a message about the skipped files to stderr and report the error
in the exit status.

tar/tar.c:
For not immediately fatal errors, exit with status 1, not the error count
(mod 256).

All:
Minor numbers are limited to 21 bits in pax's ustar format and to 18
bits in archives created by gnu tar (gnu tar wastes 3 bits for padding).
pax's and cpio's ustar format is incompatible with gnu tar's ustar
format for other reasons (see cpio/README).

16a7269ee5 When tuneing filesystems with tunefs, it is not obvious what the current
parameters are.  You can use dumpfs, but that's not obvious which settings
are tuneable, and is far from clear to the non-guru (it's like using a
hexdump of a tar archive to get a table-of-contents).

There is also an undocumented option in the man page that can be dangerous.
Suppose your disk driver decides to scramble all writes while you tell
tunefs to update all backup superblocks.

This suggested change adds a '-p' (print) switch to bring it in
line with some SVR4 systems.

c21dee177f First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.

33dc7e1b84 Reduce timeout frequency from `hz' to 0 if no ports are open or to 1 if
no ports are active, provided there are no polled ports and no
`LOSESOUTINTS' ports.  Do a little more in the interrupt handler instead.
This is a little less efficient if there are are many active ports but
a little more efficient otherwise.  Polled ports are ones with no irq
specified (as before).  `LOSESOUTINTS' ports are ones with 0x08 set in
their config flags.  Unless this flag is set, it will now take up to one
second to recover from lost output interrupts, if any.  Some 8250s and
16450s lose output interrupts.

Improve output buffering: copy the clist buffer to 2 linear buffers if
necessary and possible instead of to 1.  Handle an arbitrary queue of
buffers in the interrupt handler.  Check for waking up sleepers after
copying characters out of the clist buffer instead of before.

Delay translation of TIOCM_DTR to MCR_DTR etc. so that the top level
routines are more machine independent.

a7aa6bd1ea getnewyppasswd() in yp_passwd.c doesn't generate correct encrypted
password strings when DES isn't used; somehow the encrypted password
is corrupted and it winds up containing control chars, which yppasswdd
subsequently rejects. This breaks yppasswd on non-DES FreeBSD systems
using NIS.

Fix: scrap getnewyppasswd() entirely and use getnewpasswd() from
local_password.c, since it already works properly and is virtually
identical to getnewyppasswd() anyway. (Wish I'd noticed this sooner.)

This fixes a problem just reported on comp.unix.bsd.freebsd.misc.
