Stop binding audio devices exposed by sndiod to physical devices This a shift towards a new model: clients connect to logical devices (created with -s option) then the server routes data to/from the underlying physical device (registered with -f option). The binding may be changed at run-time with the server.device control exposed by sndioctl(1). As audio devices exposed by sndiod(8) are not bound to fixed physical devices anymore, the physical audio device number component of sndio(7) descriptors was removed. fixes, help from and ok denis, edd

Add affinity between the program and its mixer control. Currently, if there are two instances of the same program, sndiod will allocate one volume control to each. If both programs disconnect and reconnect, the information of which control is assigned to which program is lost. This makes difficult to run two instances of a player and crossfade between each other with a MIDI controller. To address this, the program chooses a 32-bit "id" (for now the process pid) and sends it to the server. The server records the id in the client's slot structure. When the server accepts a new connection, it uses the id to identify the slot the client used during the previous connection; if it was not recycled yet, it's assigned to the program.

Remplace aucat server by a new sndiod daemon aimed to be simpler
smaller and faster than aucat. It's a drop in replacement with the
following exceptions that don't affect the default setup:
- The sample rate and the encoding are a per-device parameters
thus -r and -e options must precede the corresponding -f option
- MIDI thru boxes are dynamically created and no -M option
is required anymore, so -M was removed.
- MIDI ports are exposed with a new ``midi/N'' name, rather
than abusing MIDI thru boxes.

Add a "device number" component in sndio(7) device names, allowing a
single aucat instance to handle all audio and MIDI services. Since
this partially breaks compatibility, this is a opportunitiy to fix few
other design mistakes (eg ':' being used by inet6, type name vs api
name confusion, etc..). This leads to the following names:
type[@hostname][,unit]/devnum[.option]
The device number is the minor device number for direct hardware
access (ie the 'N' in /dev/audioN). For aucat, this is the occurence
number of the -f (or -M) option.
There's a compatibility hook to keep old names working if only one
aucat server is running.

Implement a new authentication method allowing aucat and midicat to work over TCP, for instance, to expose the sound card of one machine with other machines of the network. The first client generates a 128-bit random number (aka the session cookie), saves it in $HOME/.aucat_cookie and sends it to the server. Successive clients load the cookie from $HOME/.aucat_cookie and send it to the server but the server accepts only clients whose cookie matches the session cookie. When all clients are gone, the session is over, and another cookie could start a new session, and so on. TCP is enabled on the server with the new -L option, and on the client side hostnames are specified with a new optional component in the device name. hints from damien, dlg and deraadt, tweaks from jmc

aucat (server):
- make the ``-m mode'' option per subdevice, allowing
subdevices to be play-only or rec-only even if the
server is full-duplex
- add ``monitoring'' mode (with ``-m mon''). This is a
record-only stream from which played streams can be
recorded (kind of ``record what you hear'').
- allow MIDI devices to be subscribed to the controlling
MIDI port of the server, ie what midicat does (with -f
option), but using the -q option.
- add flow control to the protocol, and serialize clock
ticks (sio_onmove() calls) and data chunks. This should
fix certain full-duplex programs, broken with ``magic''
block/buffer size combinations.
- enable 3 block latency which is the minimum theoretical.
Make -z and -b options correspond to device parameters.
- make sio_getcap(3) the same for aucat and sun backends,
ie return whatever is supported (``everything'' in the
aucat case, since everything is actulally supported).
aucat (player):
- enable ``-m mode'' option to select between monitoring
and recording when ``-o file'' is used.
- plug MIDI code to non-server codepath. The MIDI control
device is specified with the ``-q device'' option, as in
server mode.
- impliment lseek()'ing within files (controlled
through MIDI). Necessary to use aucat with a MIDI
sequencer.
midicat (thrubox):
- rename ``-f'' flag to ``-q'', so it has the
same name as in aucat (-f is still working)

Flow control blocks the client in sio_write(3). Split the data stream in a way that the pause never occurs in the middle of data chunks. Beside being more natural, this allows the client to send non-data messages during the pause (set the volume, stop playback...), rather than delaying them until the end of the pause. It's about few milliseconds only.

When starting playback, the client tries to write ``bufsz'' frames instead of ``appbufsz'', which violates the flow control mechanism. Fix this longstanding bug by enabling negative values in AMSG_MOVE messages, this way the client is notified when its stream is attached to the mixer, and can update its max transfer limit. Since this fix changes the AMSG_MOVE message format, we crank the protocol version, and thus remove code specific to the old protocol.

add a new AMSG_BYE, sent by the client to requst the server to free resources and drop the connection. This allows the client to ensuire that at any time it's using only one connection, thus only one MIDI control channel.

Currently midi capable programs can control midi hardware, but cannot cooperate with other programs. The aim of this change is to allow any program to send midi data to other programs as they were midi hardware. For instance, this change should solve the longstanding problem of using a midi sequencer with software synthesizers. More precisely: - new midicat(1) utility (actually hardlink to aucat(1)). it creates software midi thru boxes, allowing programs to send midi messages to other programs as they were midi(4) hardware. - new midi api in libsndio (see mio_open(3)), to access midi(4) devices and midicat(1) sockets in a uniform way. - new device naming scheme <service>:<unit>[.<option>], common to audio and midi. - new sndio(7) manual describing concepts and naming The current audio device naming still works, but people having scripts or configuration files containing device names could read the sndio(7) man page and slowly start updating device names. discussed with jakemsr@ and deraadt@, help form jmc@
