b7877d3fc0 Implement support for IEEE Std 1003.1b-1993 syncronous I/O: 
* if synchronized I/O file integrity completion of read operations was
  requested, set IO_SYNC in the ioflag passed to the read vnode operator.
* if synchronized I/O data integrity completion of write operations was
  requested, set IO_DSYNC in the ioflag passed to the write vnode operator.

3c658f1f41 Don't call the protocol drain routines if how == M_NOWAIT, which typically 
means we're in interrupt context.  Since we can be called from a network
hardware interrupt, we could corrupt the protocol queues we try to drain
them at that time.

c56c24f4fd Initialize the mbuf allocator _before_ autoconfiguration; it might be 
called when devices attach, take two.

Note that it is necessary that mbinit() NOT allocate memory, since it
is called before mb_map is created.  This is not a problem with the
pool allocator that is now used for mbufs and mbuf clusters.

4b039671de When checking for overflow in the residual count, test against SSIZE_MAX. 
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).

fc4828b0b4 A few small changes to how pool pages are allocated/freed: 
- If either an alloc or release function is provided, make sure both are
  provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
  since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
	uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
	kmem_alloc_poolpage()/kmem_free_poolpage()
  rather than doing it here.  These functions may use pmap hooks to
  provide alternate methods of mapping pool pages.

this argument to a `long'.

an `int', which may change in a future revision of the standard.

pointer to an array of vnodeopv_desc *'s to initialize.  Allocate
the vnode operations vectors here.  Called by vfs_attach().

Implement vfs_opv_free(), which deallocates the vnode operations
vectors.  Called by vfs_detach().

Change vfsinit() to build the initial vfs_list by traversing the
vfs_list_inital[] table, and vfs_attach()'ing those file systems.
Also, initialize special vnodeopv_descs (dead, fifo, spec) which
are not associated with any particular file system.

* Change the semantics of chown(), fchown() and lchown(): when requesting a

  for group changes.
* Since the above is a violation of the semantics specified by POSIX and
  X/Open, add corresponding compatibility syscalls: __posix_chown(),
  __posix_fchown(), __posix_lchown().  (Neither fchown() nor lchown() is
  specified by POSIX; the prefix is intended to reflect the semantics.)

cc22126721 Implement passing credentials as ancillary data on Unix domain sockets, 
enabled with the LOCAL_CREDS socket option on the listener.  Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
  on SOCK_DGRAM.
- It is not possible to forge credentials.

Different in that:
- Different credential data structure (ours does not rely on the format
  of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
  work in BSD/OS).

Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this.  :-)

2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden): 
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

94fa91f862 import chris torek's vfprintf() from libc [renamed to kprintf and all 
floating point stuff removed].

the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's.   this fixes (or adds) several
printf formats.  examples:
 %#x   - previously only supported by db_printf [not printf/sprintf]
 %8.8s - printf would print "000chuck" for "chuck" before
 %5p   - printf would print "0x    1" for value 1 before

XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
  %: - passes an additional format string and argument list recursively
  %b - used to decode error registers
  %r - int, but print in radix "db_radix" [DDB only]
  %z - 'signed hex' [DDB only]
  %n - unsigned int, but print in radix "db_radix" [DDB only]

note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg.  yuck!

while here, add comments for each function explaining what it is
supposed to do.

14cd99880c Fix the shared library versioning snafu caused by the recent changes 
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.

- In unp_setsockaddr() and unp_setpeeraddr(), if the socket name can't

  hold it.
- In unp_bind() and unp_connect(), perform a similar operation, but allocate
  one extra byte, and ensure that the pathname is nul-terminated.
