umidi(4): Clarify loops.  No functional change intended.

umidi(4): Fix fencepost in error branch.

Reported-by: syzbot+0bbf3d81c15fd1354759@syzkaller.appspotmail.com

umidi(4): Restore umidi_cs_descriptor_t type.

Had been previously deleted under the misapprehension that
usb_descriptor_t is appropriate here, but it's not -- it should not
have the bDescriptorSubtype member.

umidi(4): Parse descriptors a little more robustly.

Reported-by: syzbot+fd58d1d4dd12f8931486@syzkaller.appspotmail.com

umidi(4): Bail early if no endpoints.

kmem_alloc is unhappy with zero-size allocation.

More less kmem_zalloc(0).

Don't kmem_alloc(0) if there are no endpoints, otherwise panic. Found via
vHCI.

Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly.  Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism.  The encoding/channels/frequency
  conversions are completely handled in the upper layer.  So the hard-
  ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
  - Obsoletes query_encoding and add query_format instead.
  - Obsoletes set_params and add set_format instead.
  - Remove drain, setfd, mappage.
  - The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).

Some file paths are changed:
- dev/audio.c         -> dev/audio/audio.c (rewritten)
- dev/audiovar.h      -> dev/audio/audiovar.h
- dev/audio_dai.h     -> dev/audio/audio_dai.h
- dev/audio_if.h      -> dev/audio/audio_if.h
- dev/audiobell.c     -> dev/audio/audiobell.c
- dev/audiobellvar.h  -> dev/audio/audiobellvar.h
- dev/mulaw.[ch]      -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

remove explicit 'extern struct cfdriver <my>_cd;' and use ioconf.h

Remove dev/auconv.[ch].
 Now it is handled in dev/audio/audio.c and dev/audio/linear.c.
Remove dev/mulaw.h.
 It already have been just a link to dev/audio/mulaw.h in this
 branch.

Remove (mostly useless) usb_detach_{broadcast,wait} and replace with
cv_{broadcast,timedwait}

Really should loop on conditon.

Resolve a couple of conflicts (result of the uimin/uimax changes)

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

remove checks for failure after memory allocation calls that cannot fail:

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Use IPL_SOFTUSB instead of IPL_USB appropriately.  Transfer completions

Strictly follow the sequence abort pipe, destroy xfers, and close pipe as
API now requires.  Plug some memory leaks in some drivers while doing
this.

Also, remove up_refcnt as it was broken and helped leak more memory.

Move from usbd_{alloc,free}_xfer and usbd_{alloc,free}_buffer to
usbd_{create,destroy}_xfer.  The API change will allow future changes
to HCDs to simplify the transfer resource allocation and activation.

- move the contents of umidi{reg,var}.h into umidi.c directly as they
  are not referenced by any other file.
- remove the useless include of umidi{reg,var}.h from umidi_quirks.c.
- add reference counting and wait/broadcast support to the IO paths.
- fix the error handling in midi_attach() and midi_open().
- sprinkle KASSERT() in several places.
- drop the local interrupt lock before calling into various parts of
  the USB code.  fixes lockdebug issues, and likely hangs.

various clean ups for midi and sequencer:
midi specific:
- add reference counting for midi operations, and ensure that
  detach waits for other threads to complete before tearing
  down the device completely.
- in detach, halt midi callouts before destroying them
- re-check sc->dying after sleeping in midiread()
- in real_writebytes(), make sure we're open and not dying
- make sure we drop the interrupt lock before calling any code
  that may want to check thread locks.  this is now safe due to
  the above changes.
sequencer specific:
- avoid caching the midi softc in the sequencer softc.  instead,
  every time we want to use it, look it up again and make sure
  it still exists.
this fixes various crashes i've seen in the usb midi code when
detaching the umidi while it is active.
use __func__ in some debug messages.
- check sc->dying after sleeping in several more places, and
  convert it into EIO error where necessary.
- remove a wrong additional mutex_exit() call.
- make sure to check sc->dying under the device lock.
- fix a confusion between midi(4) unit and connected to sequencer

Step #1 of memory allocation re-organisation.

Centralised the buffer allocation routine which now supports DMA
and non-DMA capable host controllers.  Remove the
ubm_{alloc,free}m methods from usbd_bus_methods.

The buffer allocation is only allowed in thread context and,
therefore, negates the usefulness of the reserve dma code which
is removed in this change.

USBD_NO_COPY is also no longer required as usbd_transfer and
usbd_transfer_complete now track buffer usage and handle any
copying.

merge the jmcneill-usbmp branch.  many thanks to jared for the
initial work, and every one else who has tested things for me.
this is largely my fault at this point :-)

the main changes are something like:

        - usbd_bus_methods{} gains a get_lock() to enable the
          host controller to provide a lock for the USB code.
          if the lock isn't provided, old-style protection is
          (partially) applied.

        - ehci/ohci/uhci have been converted to the new
          interfaces, including mutex/cv/etc conversion.

        - usbdivar.h contains a discussion about locking and
          what locks are held for which method calls.  more
          to come for usbdi(9) here.

        - audio drivers (uaudio, umidi, auvitek) have been
          properly SMPified now that USB is ready.

        - scsi drivers have been modified to take the kernel
          lock explicitly before calling into scsi code.

        - usb pipes are associated with a lock, that is the
          same as the controller lock.  (this could be split
          up further in the future.)

        - several usbfoo_locked() or usbfoo_unlocked()
          functions have been added to the usbdi(9) to
          enable functionality with or without the USB
          lock (per controller) already being held.

the TODO.usbmp file has specific details on what is left to
do, including what device-specific changes should be done now
that the whole framework is ready.

from Tom Ivar Helbekkmo <tih@hamartun.priv.no> in PR 45909.  thanks!

merge to -current.

since we have to drop locks to call into the usb code, we need to make
sure that only one caller ends up doing something in close_out_jack().
add a "closing" member that is set when closing and error out in various
places.

with this in place i can read and write from umidi without triggering
any locking or other obvious issues, though the writing is currently
broken (it worked in 5.99.60-era.)  it runs the correct time, but no
output occurs no the synth itself.  more work needed here.

revert prior change to unbind_jacks_from_mididev(), it's wrong.
slightly clean up free_all_jacks().

make sure we're holding the kernel lock when calling in to the usb code.

two locking fixes (from PR/45909)

- during attach, release kernel lock in error path
- during midiopen, take kernel lock for USB activity

(there are more problems with locking here, this does not fix the PR)

Revert previous due to active usbmp branch(es).

Adjust-away inconsistent and trailing whitespace.

- make pipe->close method take the thread lock

- convert usb_taskq to use mutex/cv

- convert needs_explore usage into a cv on the thread lock

- remove KERNEL_*LOCK from uaudio and umidi, since we're supposedly
  MPSAFE here now

- use IPL_SCHED instead of IPL_USB (aka biglocked) interrupts

- drop the audio thread lock when calling into usb when it may sleep,
  avoiding a deadlock between audiowrite and audioioctl.  this fixes
  mixerctl -a vs. playing hanging the system
  XXX probably need to check this in a bunch more places.

avoid taking the thread lock when the kernel lock is needed.
now umidi detaches successfully.

convert to kmem.  also, zero all contents properly.  now umidi begins
to work.  crashed when i unplugged the synth.  for a later time.

Move KASSERT down to the point where the endpoint is known to exist.

More use of uninitialized memory

fix non-DIAGNOSTIC build

fix non-DIAGNOSTIC build

several steps towards making umidi appear to work:

- split out_solicit() into locked and unlocked front end, and use the
  unlocked version from the softintr

- kill sc_intr_lock, midi doesn't really use it (XXX finish this?
  change this? in the midi* code)

- convert tsleep()/wakeup() to cv

- move some free's out of the lock

- KASSERT() lock is held in a few more places


TODO:

- malloc -> kmem

- crashes in midiclose(), doesn't actually play things to the right
  device.  "midiplay -d midi1 -xv" plays out my midi@pcppi speaker,
  and then the above crash.  clearly something is calling the wrong
  sub-device callbacks!

complete the port to audiomp:  take kernel lock in a few places for
USB (like uaudio), kill most of the spl* uses.

Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:

  Add MP locking to the audio drivers.

  Making the audio drivers MP safe is necessary before efforts
  can be made to make the VM system MP safe.

  The are two locks per device instance, an ISR lock and
  a character device lock. The ISR lock replaces calls to
  splaudio()/splx(), and will be held across calls to device
  methods which were called at splaudio() before (e.g.
  trigger_output). The character device lock is held across
  calls to nearly all of the methods, excluding some only
  used for initialization, e.g. get_locks.

Welcome to 5.99.57.

port umidi to audiomp: get_locks support, take locks in interrupts.

untested, and midi in this branch has general problems still anyway.

In umidi_attach(), adjust aprint functions match what uaudio(4) does,
so that '\n' is printed in the appropriate places.

Overhaul of USB stack, mostly DMA related

This applies to NetBSD 4.99.13 (March 1, 2007)

usbdi(9) interface is based on FreeBSD version, excluding
 - removal of portability code

Patch most NetBSD changes, excluding
 - DMA memory "reserve", since we don't need contiguous buffers any longer
 - volatiles in DMA structure, since it should not be needed
   with proper bus_dmamap_sync(9)s

DMA/non-DMA memory management overhaul
 - Move all DMA related code to usb_mem.[ch]
   (add usb_alloc_buffer_dma(), usb_free_buffer_dma(), etc.).
   XXX Should usb_mem.[ch] be renamed as usb_mem_dma.[ch] ?
 - Add corresponding non-DMA code to usb_mem_nodma.[ch] .
   Currently just use malloc(9).
 - Above files are conditionally used by config framework (added
   attributes to conf/files and dev/usb/files.usb).
 - Add diagnostic panics when resource allocation is requested
   on interrupt context.
 - Change memory allocations (that require context) from NOWAIT to WAITOK.

Allocate DMA/non-DMA buffer per host interface, not globally.
 advantage:	Buffers can be freed on detaching host interface.
		Activity of a host interface does not affect others.
 disadvantages:	It possibly consumes more memory.

API changes
 - usbd_alloc_xfer() is changed:
    old: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev);
    new: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev,
		usbd_pipe_handle pipe);
 - pipe argument of usbd_setup_*xfer() are now unused
   XXX the pipe argument should be removed?
 - add mapping APIs

Introduce different autoconf interface attributes for USB drivers
matching (and handling) a whole device and those which match an
interface only. This will allow to enforce some rules, eg that
the former don't use interface information for matching or that the
latter don't modify global device state.
The previous way left too much freedom do the drivers which led to
inconsistencies and abuse.
For now, I've not changed locators and submatch rules, this will
happen later.
There should not be any change in behaviour, except in the case of
some drivers which did behave inconsistently:
if_atu, if_axe, uep: matched the configured device in the interface
 stage, but did configuration again. I've converted them to match
 in the device stage.
ustir, utoppy: matched in the interface stage, but only against
 vendor/device information, and used any configuration/interface
 without checking. Changed to match in device stage, and added
 some simple code to configure and use the first interface.
If you have one of those devices, please test!

Allow getinfo (and therefore midiplay -l) to reveal something useful for
umidi devices.

Annotate devices that lack output interrupts in the dmesg with (cpu-
intensive output) so users can easily tell which ones to prefer for
bulk output.

A flag is added to the midi_hw_if_ext struct for the hardware to specify
that it would like compression of data to be transmitted. It will still
receive a message at a time, with the status and channel passed as
arguments, but the message buffer will omit the status byte when possible.
umidi now uses this flag when talking to Midiman devices, which do not do
their own compression, so as to make best use of the MIDI 1.0 bandwidth on
the far side.

The native protocol of a quirk-Midiman device does not require a packet
per message, but allows messages to be packed in and across packets.
This can save a bit of USB bandwidth, but the real benefit of this change
will come when the hw_if_ext is updated to allow midi(4) to pass down
compressed messages. The Midiman device doesn't do its own compression,
so that will be a win when the data rate on the far side is limited
to MIDI 1.0.

PR kern/33590.

Input on a jack that is not open for reading was discarded without
rearming the input transfer, so subsequent input would cease on other
jacks sharing the same endpoint. I thought I must have broken this, but
actually it broke five years ago in r1.4.

The breakage in the dump_ep() debug function was mine, though.

@.n.o e-mail address, and a couple of corrections to the mechanical
merge, found by eyeball. Now to see how many gcc will catch....

Now for Phase Two. The patched files have been rolled forward again, with
a naive mechanical resolution of conflicts. Now to compare the diffs and
make sure the resolutions made sense. Sleep first.

Learned of two ugly corners in MIDI protocol that made the state machine
overly pedantic. Both have to do with the End SysEx byte, 0xf7. First, it
is allowed not only at the end of a SysEx message, but anywhere else any
status byte can appear (and in that case has no meaning). Second, it is
not even required at the end of a SysEx message - any subsequent status
byte implicitly ends the SysEx, and this is not considered an error.

I don't like these provisions because they make it even harder to detect
errors in a corrupted MIDI stream, but as MIDI gets sent increasingly over
error-correcting transports I suppose that is less of a concern. In any
case, though midi(4) will accept data (input from device or data from
write(2)) with stray or dropped End SysEx bytes, it will always ensure
that output to the device, and data for read(2), has End SysEx only and
always at the ends of SysEx messages.

Spotted a bug in a buffer condition. Never saw any symptom, but it's a
bug nonetheless.

Using full wMaxPacketSize transfers on receive (earlier patch, kern/32441)
was a substantial performance improvement, so it made sense to do so with
transmit buffers also (this patch).  A little benchmarking....

...transmitting to one port only of a Midisport 2x4, achieving barely 16%

...sustained simultaneous transmission to all four ports at full MIDI

This patch should be fuzz-free on 2.0 sources after application of the
kern/32441, 32442, and 32567 patches. There has been little cvs activity
on the affected files since 2.0, so applying to current sources should
be straightforward.

The two choices CN_SEQ_GLOBAL and CN_SEQ_PER_EP cannot cover all devices,
some are wired arbitrarily oddly and need a CN_FIXED quirk to specify
the cable number mappings explicitly.  But then as a result of those
mappings, the automatically bound mididevice unit numbers might not match
the order of the device's physical jacks or blinkenlights, so an MD_FIXED
quirk is needed to specify that order as well.  It turns out the cn_base
field added earlier was neither necessary (at the time) nor sufficient
(to handle CN_FIXED), so it's gone now.

Q: How do you tell when you've got the cable number associations wrong on
   a Midisport 2x4?
A: Everything works right except data-rate throttling - you'll be able to
   send data to certain ports at rates far in excess of the MIDI data rate
   (and lose most of it). If you never transmit that fast, you'll never
   notice.

So testing for a sane data transfer rate (use dd to blast a stream of MIDI
data at the rmidi device, it'll report the rate on completion) is probably
a wise testing step when adding support for a new umidi device.

Patch to account explicitly for the prior inconsistency in the treatment of
cable numbers. Also contains a (functionally insignificant) change to the
declaration of endpoint buffers introduced in kern/32441, which will be
useful in a forthcoming patch.  This patch should be fuzz-free on 2.0
source after the 32441 and 32442 patches.

Active Sense now handled for receive as well as for transmit. Following the
spec, if no Active Sense is seen on receive, no special behavior applies,
but if an Active Sense is seen then any absence of received data exceeding
300ms thereafter will be signalled as a read EOF on the rmidi device.
Receipt of any further data will clear the EOF condition, and operation
resumes as if no Active Sense has been seen.

Also moved some selnotify's out of locks so they don't deadlock against
the corresponding kevent filters.

This concludes this round of midi hacking (except for possibly improving
the safety of how pending callouts and interrupts are canceled on device
detach. Other fixes/enhancements to the midi subsystems will get their
own patches.

The FST now handles the equivalence between NoteOn (velocity 0) and a
NoteOff with velocity 64, both for canonicalizing (always produce NoteOff)
and compressing (produce whichever allows a current running status to be
exploited). The code from sequencer that attempted to model this behavior
and running status has been superseded and removed. Also removed the
EBADF checks I added to sequencer earlier, as they're handled in a layer
above.

umidi now uses hw_if_ext and no longer has its own approximate midi state
machine.  This patch is relative to umidi.c and umidivar.h already patched
by midiman.pat (kern/32441).

Changing the input logic to use wMaxPacketSize transfers instead of
4 bytes may have nailed the input data loss problem; it seems rock
solid now. This patch is against 2.0 sources but there's been so
little CVS activity on those files it should be easy to apply.

Had output and input working in 1.6.2, but managed to lose input in
adapting the patch to 2.0.  Now it's back.  TODO: find out if there's
a way to improve input response (size of simultaneous chords that can
be played without dropping data) - perhaps by increasing the size of
the endpoint's xfer buffer, or learning something more about the usb
interrupt transfers.

Applies fuzz-free to 2.0 sources; adds support for Midiman Midisport 2x4.

Now for Phase One. The patches to be applied in sequence were created
and tested against 2.0 sources. To begin, let CVS roll the affected files
back to that historic state. The reverse operation will be used (and
will involve some manual merging) after the patches have been applied.
Naturally, intermediate stages on this branch will not be directly
compilable (unless merged into a 2.0 checkout).
