7c3808562a - Catch up with ongoing rwatson's socket work;
- Fix a couple of LORs and panics;

- Temporarily remove the code that tries to cleanup sockets that stuck
  on accepting queues (both complete and incomplete). I'm taking an ostrich
  approach here until I find a better way to deal with sockets that were
  disconnected before accepting (i.e. while socket was on complete or
  incomplete accept queue).

b0668f7151 soreceive_generic(), and sopoll_generic(). Add new functions sosend(),
soreceive(), and sopoll(), which are wrappers for pru_sosend,
pru_soreceive, and pru_sopoll, and are now used univerally by socket
consumers rather than either directly invoking the old so*() functions
or directly invoking the protocol switch method (about an even split
prior to this commit).

This completes an architectural change that was begun in 1996 to permit
protocols to provide substitute implementations, as now used by UDP.
Consumers now uniformly invoke sosend(), soreceive(), and sopoll() to
perform these operations on sockets -- in particular, distributed file
systems and socket system calls.

a152f8a361 Change semantics of socket close and detach. Add a new protocol switch
function, pru_close, to notify protocols that the file descriptor or
other consumer of a socket is closing the socket.  pru_abort is now a
notification of close also, and no longer detaches.  pru_detach is no
longer used to notify of close, and will be called during socket
tear-down by sofree() when all references to a socket evaporate after
an earlier call to abort or close the socket.  This means detach is now
an unconditional teardown of a socket, whereas previously sockets could
persist after detach of the protocol retained a reference.

This faciliates sharing mutexes between layers of the network stack as
the mutex is required during the checking and removal of references at
the head of sofree().  With this change, pru_detach can now assume that
the mutex will no longer be required by the socket layer after
completion, whereas before this was not necessarily true.

c4e3f62cc1 Add new SIOC_HCI_RAW_NODE_LIST_NAMES ioctl. User-space applications can
use this ioctl to obtain the list of HCI nodes. User-space application
is expected to preallocate 'ng_btsocket_hci_raw_node_list_names' structure
and set limit in 'num_nodes' field. The 'nodes' field should be allocated
as well and it should have space for at least 'num_nodes' elements.

The SIOC_HCI_RAW_NODE_LIST_NAMES should be issued on bound raw HCI socket.
It does not really really matter what HCI name the socket is bound to, as
long as it is not empty.

bc725eafc7 Chance protocol switch method pru_detach() so that it returns void
rather than an error.  Detaches do not "fail", they other occur or
the protocol flags SS_PROTOREF to take ownership of the socket.

soclose() no longer looks at so_pcb to see if it's NULL, relying
entirely on the protocol to decide whether it's time to free the
socket or not using SS_PROTOREF.  so_pcb is now entirely owned and
managed by the protocol code.  Likewise, no longer test so_pcb in
other socket functions, such as soreceive(), which have no business
digging into protocol internals.

Protocol detach routines no longer try to free the socket on detach,
this is performed in the socket code if the protocol permits it.

In rts_detach(), no longer test for rp != NULL in detach, and
likewise in other protocols that don't permit a NULL so_pcb, reduce
the incidence of testing for it during detach.

netinet and netinet6 are not fully updated to this change, which
will be in an upcoming commit.  In their current state they may leak

ac45e92ff2 Change protocol switch pru_abort() API so that it returns void rather
than an int, as an error here is not meaningful.  Modify soabort() to
unconditionally free the socket on the return of pru_abort(), and
modify most protocols to no longer conditionally free the socket,
since the caller will do this.

This commit likely leaves parts of netinet and netinet6 in a situation
where they may panic or leak memory, as they have not are not fully
updated by this commit.  This will be corrected shortly in followup

d374e81efd Push the assignment of a new or updated so_qlimit from solisten()
following the protocol pru_listen() call to solisten_proto(), so
that it occurs under the socket lock acquisition that also sets
SO_ACCEPTCONN.  This requires passing the new backlog parameter
to the protocol, which also allows the protocol to be aware of
changes in queue limit should it wish to do something about the
new queue limit.  This continues a move towards the socket layer
acting as a library for the protocol.

Bump __FreeBSD_version due to a change in the in-kernel protocol
interface.  This change has been tested with IPv4 and UNIX domain
sockets, but not other protocols.

82e1becc5f Fix dangling callout problem in the Bluetooth L2CAP code that leads to
panic. The panic happens when outgoing L2CAP connection descriptor is
deleted with the L2CAP command(s) pending in the queue. In this case when
the last L2CAP command is deleted (due to cleanup) and reference counter
for the L2CAP connection goes down to zero the auto disconnect timeout
is incorrectly set. pjd gets credit for tracking this down and committing
bandaid.

does not have bDeviceClass, bDeviceSubClass and bDeviceProtocol set to required

0daccb9c94 In the current world order, solisten() implements the state transition of
a socket from a regular socket to a listening socket able to accept new
connections.  As part of this state transition, solisten() calls into the
protocol to update protocol-layer state.  There were several bugs in this
implementation that could result in a race wherein a TCP SYN received
in the interval between the protocol state transition and the shortly
following socket layer transition would result in a panic in the TCP code,
as the socket would be in the TCPS_LISTEN state, but the socket would not
have the SO_ACCEPTCONN flag set.

This change does the following:

- Pushes the socket state transition from the socket layer solisten() to
  to socket "library" routines called from the protocol.  This permits
  the socket routines to be called while holding the protocol mutexes,
  preventing a race exposing the incomplete socket state transition to TCP
  after the TCP state transition has completed.  The check for a socket
  layer state transition is performed by solisten_proto_check(), and the
  actual transition is performed by solisten_proto().

- Holds the socket lock for the duration of the socket state test and set,
  and over the protocol layer state transition, which is now possible as
  the socket lock is acquired by the protocol layer, rather than vice
  versa.  This prevents additional state related races in the socket
  layer.

This permits the dual transition of socket layer and protocol layer state
to occur while holding locks for both layers, making the two changes
atomic with respect to one another.  Similar changes are likely require
elsewhere in the socket/protocol code.

980b8b89eb Make default RFCOMM session MTU match default L2CAP MTU.
This is just a workaround for a know problem with Motorola E1000
phone. Something is wrong with the configuration of L2CAP/RFCOMM
channel. Even though we set L2CAP MTU to 132 bytes (default RFCOMM
MTU 127 + 5 bytes RFCOMM frame header) and the phone accepts it,
the phone still sends oversized L2CAP packets. It appears that the
phone wants to use bigger (667 bytes) RFCOMM frames, but it does
not segment them according to the configured L2CAP MTU. The 667
bytes RFCOMM frame size corresponds to the default L2CAP MTU of
672 bytes (667 + 5 bytes RFCOMM frame header).

This problem only appears if connection was initiated from the
phone. I'm not sure who is at fault here, so for now just put
workaround in place. Quick look at the spec did not reveal any
anwser.

4f240aff01 Move ng_socket and ng_btsocket initialization to SI_SUB_PROTO_DOMAIN as they
call net_add_domain(). Calling this function too early (or late) breaks
assertations about the global domains list.
Actually it should be forbidden to call net_add_domain() outside of
SI_SUB_PROTO_DOMAIN completely as there are many places where we traverse
the domains list unprotected, but for now we allow late calls (mostly to
support netgraph). In order to really fix this we have to lock the domains
list in all places or find another way to ensure that we can safely walk the
list while another thread might be adding a new domain.
