44956c9863 Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

86fea6be59 o Untangle the confusion with the malloc flags {M_WAITOK, M_NOWAIT} and
the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}.
o Fix a bpf_compat issue where malloc() was defined to just call
  bpf_alloc() and pass the 'canwait' flag(s) along.  It's been changed
  to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
  flag (and only one of those two).

be created incorrectly for requests larger than NB_SORECEIVE_CHUNK bytes.

3c30400408 Increase send/receive queue to accomodate large readx/writex requests.
Receive packets in a small pieces (NB_SORECEIVE_CHUNK), so TCP slowstart will
get its ACKs faster.

243917fe3b Lock down a socket, milestone 1.
o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
  socket buffer. The mutex in the receive buffer also protects the data
  in struct socket.

o Determine the lock strategy for each members in struct socket.

o Lock down the following members:

  - so_count
  - so_options
  - so_linger
  - so_state

o Remove *_locked() socket APIs.  Make the following socket APIs
  touching the members above now require a locked socket:

 - sodisconnect()
 - soisconnected()
 - soisconnecting()
 - soisdisconnected()
 - soisdisconnecting()
 - sofree()
 - soref()
 - sorele()
 - sorwakeup()
 - sotryfree()
 - sowakeup()
 - sowwakeup()

960ed29c4b Revert the change of #includes in sys/filedesc.h and sys/socketvar.h.
Requested by:	bde

Since locking sigio_lock is usually followed by calling pgsigio(),
move the declaration of sigio_lock and the definitions of SIGIO_*() to
sys/signalvar.h.

While I am here, sort include files alphabetically, where possible.

9c4d63da6d o Make the credential used by socreate() an explicit argument to
socreate(), rather than getting it implicitly from the thread
  argument.

o Make NFS cache the credential provided at mount-time, and use
  the cached credential (nfsmount->nm_cred) when making calls to
  socreate() on initially connecting, or reconnecting the socket.

This fixes bugs involving NFS over TCP and ipfw uid/gid rules, as well
as bugs involving NFS and mandatory access control implementations.

1b36970495 Back out scanning file descriptors with holding a process lock.
selrecord() requires allproc sx in pfind(), resulting in lock order
reversal between allproc and a process lock.

265fc98f36 - Convert msleep(9) in select(2) and poll(2) to cv_*wait*(9).
- Since polling should not involve sleeping, keep holding a
  process lock upon scanning file descriptors.

- Hold a reference to every file descriptor prior to entering
  polling loop in order to avoid lock order reversal between
  lockmgr and p_mtx upon calling fdrop() in fo_poll().
  (NOTE: this work has not been done for netncp and netsmb
  yet because a socket itself has no reference counts.)
