kleink 5350df2953 Per POSIX, fail with EINVAL if advisory locking is attempted on a file type
that doesn't support it, rather than using a homegrown EBADF or EOPNOTSUPP.

kleink 7b07ad780a Per XNS Issue 5, calling recvmsg(2) or sendmsg(2) with an msg.msg_iovlen less
than or equal to 0 shall fail with EMSGSIZE; the latter condition was not being
checked for.  Also, document the msg.msg_iovlen > {IOV_MAX} case.

perry 275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.

kleink 3d9b4a4320 Fix two off-by-one bugs, both present in each recvmsg(2) and sendmsg(2):
* the first one would cause an unnecessary malloc() of iovec storage for
  a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
  been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
  UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.

kleink 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.

thorpej 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.

thorpej 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.

kleink 17de9df6c1 Reject an iovcnt argument of 0 to readv(), writev(), preadv() and pwritev()
as invalid.  This has been stated by the respective manual pages at least
since Net/2, and is the behaviour specified by XSH5.

thorpej 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).

thorpej 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.
