* ALSA: usb-audio: fix missing input volume controls in MAYA44 USB(+)Clemens Ladisch2015-08-071-5/+3
| | | | | | | | | | | | | | | | | | | | | commit ea114fc27dc0cb9a550b6add5426720feb66262a upstream. The driver worked around an error in the MAYA44 USB(+)'s mixer unit descriptor by aborting before parsing the missing field. However, aborting parsing too early prevented parsing of the other units connected to this unit, so the capture mixer controls would be missing. Fix this by moving the check for this descriptor error after the parsing of the unit's input pins.

* ALSA: emux: Fix mutex deadlock in OSS emulationTakashi Iwai2015-08-072-16/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 1c94e65c668f44d2c69ae7e7fc268ab3268fba3e upstream. The OSS emulation in synth-emux helper has a potential AB/BA deadlock at the simultaneous closing and opening: close -> snd_seq_release() -> sne_seq_free_client() -> snd_seq_delete_all_ports(): takes client->ports_mutex -> port_delete() -> snd_emux_unuse(): takes emux->register_mutex open -> snd_seq_oss_open() -> snd_emux_open_seq_oss(): takes emux->register_mutex -> snd_seq_event_port_attach() -> snd_seq_create_port(): takes client->ports_mutex This patch addresses the deadlock by reducing the rance taking emux->register_mutex in snd_emux_open_seq_oss(). The lock is needed for the refcount handling, so move it locally. The calls in emux_seq.c are already with the mutex, thus they are replaced with the version without mutex lock/unlock.

* ALSA: emux: Fix mutex deadlock at unloadingTakashi Iwai2015-08-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | commit 07b0e5d49d227e3950cb13a3e8caf248ef2a310e upstream. The emux-synth driver has a possible AB/BA mutex deadlock at unloading the emu10k1 driver: snd_emux_free() -> snd_emux_detach_seq(): mutex_lock(&emu->register_mutex) -> snd_seq_delete_kernel_client() -> snd_seq_free_client(): mutex_lock(&register_mutex) snd_seq_release() -> snd_seq_free_client(): mutex_lock(&register_mutex) -> snd_seq_delete_all_ports() -> snd_emux_unuse(): mutex_lock(&emu->register_mutex) Basically snd_emux_detach_seq() doesn't need a protection of emu->register_mutex as it's already being unregistered. So, we can get rid of this for avoiding the deadlock. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
* ALSA: emu10k1: Fix card shortname string buffer overflowTakashi Iwai2015-08-072-4/+6
| | | | | | | | | | | | | | | | | commit d02260824e2cad626fb2a9d62e27006d34b6dedc upstream. Some models provide too long string for the shortname that has 32bytes including the terminator, and it results in a non-terminated string exposed to the user-space. This isn't too critical, though, as the string is stopped at the succeeding longname string. This patch fixes such entries by dropping "SB" prefix (it's enough to fit within 32 bytes, so far). Meanwhile, it also changes strcpy() with strlcpy() to make sure that this kind of problem won't happen in future, too.

The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read acquire the emu_lock before accessing the FPGA. The function used to access the FPGA (snd_emu1010_fpga_read) also tries to take the emu_lock which causes a deadlock. Remove the outer locking in the proc-functions (guarding only the already safe fpga read) to prevent this deadlock.

* ALSA: ak411x: Fix stall in work callbackTakashi Iwai2015-03-062-19/+16
| | | | | | | | | | | | | | | | | | | commit 4161b4505f1690358ac0a9ee59845a7887336b21 upstream. When ak4114 work calls its callback and the callback invokes ak4114_reinit(), it stalls due to flush_delayed_work(). For avoiding this, control the reentrance by introducing a refcount. Also flush_delayed_work() is replaced with cancel_delayed_work_sync(). The exactly same bug is present in ak4113.c and fixed as well.

* ALSA: seq-dummy: remove deadlock-causing events on closeClemens Ladisch2015-02-201-31/+0
| | | | | | | | | | | | | | | | | | commit 0767e95bb96d7fdddcd590fb809e6975d93aebc5 upstream. When the last subscriber to a "Through" port has been removed, the subscribed destination ports might still be active, so it would be wrong to send "all sounds off" and "reset controller" events to them. The proper place for such a shutdown would be the closing of the actual MIDI port (and close_substream() in rawmidi.c already can do this). This also fixes a deadlock when dummy_unuse() tries to send events to its own port that is already locked because it is being freed.

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

| | | | | | | | | | | | | | | | | | commit 95926035b187cc9fee6fb61385b7da9c28123f74 upstream. The emu10k1 voice allocator takes voice_lock spinlock. When there is no empty stream available, it tries to release a voice used by synth, and calls get_synth_voice. The callback function, snd_emu10k1_synth_get_voice(), however, also takes the voice_lock, thus it deadlocks. The fix is simply removing the voice_lock holds in snd_emu10k1_synth_get_voice(), as this is always called in the spinlock context.
