- Eliminate so_nbio and turn it into a bit SS_NBIO in so_state.
- Introduce MSG_NBIO so that we can turn non blocking i/o on a per call basis
- Use MSG_NBIO to fix the XXX: multi-threaded issues on the fifo sockets.
- Don't set SO_CANTRCVMORE, if we were interrupted (perhaps do it for all
  errors?).

Fix kern/45093 as discussed on tech-kern@:
http://mail-index.netbsd.org/tech-kern/2011/06/17/msg010734.html

The cause of the problem is that the so_pendfree is processed with
the softnet_lock held at one point, and processing the list
calls sodoloanfree() which may kpause(). As the thread sleeps with
softnet_lock held, it ultimately cause a deadlock (see the PR or tech-kern
thread for details).
Although it should be possible to call sodopendfree() after releasing
the socket lock, it's not so easy to know where he socket lock is held and
where it's not, so we may hit the issue again later.
Add a kernel thread to handle the so_pendfree list, and wake up this
thread when adding mbufs to this list. Get rid of the various sodopendfree()
calls, hopefully fixing definitively the problem.

* Arrange for interfaces that create new file descriptors to be able to
  set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

    - Add F_DUPFD_CLOEXEC to fcntl(2).
    - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
    - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
      for socket(2) and socketpair(2).
    - Add new paccept(2) syscall that takes an additional sigset_t to alter
      the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
      SOCK_NONBLOCK.
    - Add new mode character 'e' to fopen(3) and popen(3) to open pipes
      and file descriptors for close on exec.
    - Add new kqueue1(2) syscall with a new flags argument to open the
      kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.

* Fix the system calls that take socklen_t arguments to actually do so.

* Don't include userland header files (signal.h) from system header files
  (rump_syscallargs.h).

* Bump libc version for the new syscalls.

If a multithreaded app closes an fd while another thread is blocked in
read/write/accept, then the expectation is that the blocked thread will
exit and the close complete.
Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.
Also rename fo_abort() to fo_restart() (this used to be fo_drain()).
Fixes PR/26567

Rename fo_drain() to fo_abort(), 'drain' is used to mean 'wait for output
do drain' in many places, whereas fo_drain() was called in order to force
blocking read()/write() etc calls to return to userspace so that a close()
call from a different thread can complete.
In the sockets code comment out the broken code in the inner function,
it was being called from compat code.

Make ifconfig(8) set and display preference numbers for IPv6
addresses.  Make the kernel support SIOC[SG]IFADDRPREF for IPv6
interface addresses.

In in6ifa_ifpforlinklocal(), consult preference numbers before
making an otherwise arbitrary choice of in6_ifaddr.  Otherwise,
preference numbers are *not* consulted by the kernel, but that will
be rather easy for somebody with a little bit of free time to fix.

Please note that setting the preference number for a link-local
IPv6 address does not work right, yet, but that ought to be fixed
soon.

In support of the changes above,

1 Add a method to struct domain for "externalizing" a sockaddr, and
  provide an implementation for IPv6.  Expect more work in this area: it
  may be more proper to say that the IPv6 implementation "internalizes"
  a sockaddr.  Add sockaddr_externalize().

2 Add a subroutine, sofamily(), that returns a struct socket's address
  family or AF_UNSPEC.

3 Make a lot of IPv4-specific code generic, and move it from
  sys/netinet/ to sys/net/ for re-use by IPv6 parts of the kernel and
  ifconfig(8).

sleeping while holding a reference to the descriptor. Implemented only for
sockets but should be extended to pipes, fifos, etc.

following, which would have hung until the process got a signal.

1) Introduce a new socket option, (SOL_SOCKET, SO_NOHEADER), that
   tells a socket that it should both add a protocol header to tx'd
   datagrams and remove the header from rx'd datagrams:

        int onoff = 1, s = socket(...);
        setsockopt(s, SOL_SOCKET, SO_NOHEADER, &onoff);

2) Add an implementation of (SOL_SOCKET, SO_NOHEADER) for raw IPv4
   sockets.

3) Reorganize the protocols' pr_ctloutput implementations a bit.
   Consistently return ENOPROTOOPT when an option is unsupported,
   and EINVAL if a supported option's arguments are incorrect.
   Reorganize the flow of code so that it's more clear how/when
   options are passed down the stack until they are handled.

   Shorten some pr_ctloutput staircases for readability.

4) Extract common mbuf code into subroutines, add new sockaddr
   methods, and introduce a new subroutine, fsocreate(), for reuse
   later; use it first in sys_socket():

struct mbuf *m_getsombuf(struct socket *so)

        Create an mbuf and make its owner the socket `so'.

struct mbuf *m_intopt(struct socket *so, int val)

        Create an mbuf, make its owner the socket `so', put the
        int `val' into it, and set its length to sizeof(int).


int fsocreate(..., int *fd)

        Create a socket, a la socreate(9), put the socket into the
        given LWP's descriptor table, return the descriptor at `fd'
        on success.

void *sockaddr_addr(struct sockaddr *sa, socklen_t *slenp)
const void *sockaddr_const_addr(const struct sockaddr *sa, socklen_t *slenp)

        Extract a pointer to the address part of a sockaddr.  Write
        the length of the address  part at `slenp', if `slenp' is
        not NULL.

socklen_t sockaddr_getlen(const struct sockaddr *sa)

        Return the length of a sockaddr.  This just evaluates to
        sa->sa_len.  I only add this for consistency with code that
        appears in a portable userland library that I am going to
        import.

const struct sockaddr *sockaddr_any(const struct sockaddr *sa)

        Return the "don't care" sockaddr in the same family as
        `sa'.  This is the address a client should sobind(9) if it
        does not care the source address and, if applicable, the
        port et cetera that it uses.

const void *sockaddr_anyaddr(const struct sockaddr *sa, socklen_t *slenp)

        Return the "don't care" sockaddr in the same family as
        `sa'.  This is the address a client should sobind(9) if it
        does not care the source address and, if applicable, the

From FreeBSD:

  Fix a bug in sblock() that has existed since revision 1.1 from BSD:
  correctly return an error if M_NOWAIT is passed to sblock() and the

Similarly split sys_accept() and change the split in recvmsg() so that it

  do_sys_recvmsg().
Factor out the code that writes socked names to userspace (from mbuf) to

Extract the code that writes socket 'control' (CMSG) data out to userspace,
  being more careful about the 'fd' that may exist inside SCM_RIGHTS msgs.
  (they still get lost if some of the latter copyout calls fail).

Rework to make  FAST_IPSEC PF_KEY dumps unicast and reliable:

Introduce new socket-layer function sbappendaddrchain() to
sys/kern/uipc_socket2.c: like sbappendaddr(), only takes a chain of
records and appends the entire chain in one pass. sbappendaddrchain()
also takes an `sbprio' argument, which indicates the caller requires
special `reliable' handling of the socket-buffer.  `sbprio' is
described in sys/sys/socketvar.h, although (for now) the different
levels are not yet implemented.

Rework sys/netipsec/key.c PF_KEY DUMP responses to build a chain of
mbuf records, one record per dump response. Unicast the entire chain
to the requestor, with all-or-none semantics.

Changed files;
 	sys/socketvar.h kern/uipc_socket2.c netipsec/key.c
Reviewed by:
	Jason Thorpe, Thor Lancelot Simon, post to tech-kern.

Todo: request pullup to 2.0 branch.  Post-2.0, rework sysctl() API for
dumps to use new record-chain constructors. Actually implement
the distinct service levels in sbappendaddrchain() so we can use them
to make PF_KEY ACQUIRE messages more reliable.

Eliminate several uses of `curproc' from the socket-layer code and from NFS.

Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded  by Matt Thomas.

Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize.   Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.

Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.

Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

Make insertion of data into socket buffers O(C):
* Keep pointers to the first and last mbufs of the last record in the
  socket buffer.
* Use the sb_lastrecord pointer in the sbappend*() family of functions
  to avoid traversing the packet chain to find the last record.
* Add a new sbappend_stream() function for stream protocols which
  guarantee that there will never be more than one record in the
  socket buffer.  This function uses the sb_mbtail pointer to perform
  the data insertion.  Make TCP use sbappend_stream().

On a profiling run, this makes sbappend of a TCP transmission using
a 1M socket buffer go from 50% of the time to .02% of the time.

implement the recently introduced EMUL_BSD_ASYNCIO_PIPE emulation package
flag.

EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original
BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and
write(). OSes without this flag do not expect any SIGIO to be fired on
read() and write() for pipes, even when async I/O was requested. As far as
we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and
Darwin.

Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
call with F_FSCTL set and F_SETFL calls generate calls to a new

Ensure that you can only bind a more specific address when it is done by the
same uid or by root.

This code is from FreeBSD. (Whilst it was originally obtained from OpenBSD,
FreeBSD fixed it to work with multicast. To quote the commit message:
    - Don't bother checking for conflicting sockets if we're binding to a
      multicast address.
    - Don't return an error if we're binding to INADDR_ANY, the conflicting
      socket is bound to INADDR_ANY, and the conflicting socket has
      SO_REUSEPORT set.

change sockargs()'s second argument to be a const void *.  It used
to be a caddr_t, but since it's being passed constant user argument pointers
it needs to be const, and since it's being passed a variety of argument
pointer types it makes sense to change it to void *.  That argument is
simply being handed to copyin().
