* [tree-wide] finally take no_llseek outAl Viro2024-09-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

* | ALSA: ump: Handle MIDI 1.0 Function Block in MIDI 2.0 protocolTakashi Iwai2024-08-064-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UMP v1.1 spec says in the section 6.2.1: "If a UMP Endpoint declares MIDI 2.0 Protocol but a Function Block represents a MIDI 1.0 connection, then may optionally be used for messages to/from that Function Block." It implies that the driver can (and should) keep MIDI 1.0 CVM exceptionally for those FBs even if UMP Endpoint is running in MIDI 2.0 protocol, and the current driver lacks of it. This patch extends the sequencer port info to indicate a MIDI 1.0 port, and tries to send/receive MIDI 1.0 CVM as is when this port is the source or sink. The sequencer port flag is set by the driver at parsing FBs and GTBs although application can set it to its own user-space clients, too.

* ALSA: seq: ump: Optimize conversions from SysEx to UMPTakashi Iwai2024-07-261-14/+23
| | | | | | | | | | | | | | | | | | | | | | | The current conversion from the legacy SysEx event to UMP SysEx packet in the sequencer core has a couple of issues: * The first packet trims the SysEx start byte (0xf0), hence it contains only 5 bytes instead of 6. This isn't wrong, per specification, but it's strange not to fill 6 bytes. * When the SysEx end marker (0xf7) is placed at the first byte of the next packet, it'll end up with an empty data just with the END status. It can be rather folded into the previous packet with the END status. This patch tries to address those issues. The first packet may have 6 bytes even with the SysEx start, and an empty packet with the SysEx end marker is omitted.

* ALSA: seq: ump: Skip useless ports for static blocksTakashi Iwai2024-07-171-0/+16
| | | | | | | | | | | | | | | | | | When the UMP Endpoint is configured with static blocks, the block configuration will never change, hence the unused ports will be unchanged as well. Creating sequencer ports for those unused ports is simply useless, and it might be rather confusing for users. The idea behind the inactive ports was for allowing connections from/to ports that can become usable later, but this will never happen for inactive groups in static blocks. Let's change the sequencer UMP binding to skip those unused ports when the UMP EP is with static blocks.

* ALSA: seq: Add tempo base unit for MIDI2 Set Tempo messagesTakashi Iwai2024-07-064-9/+26
| | | | | | | | | | | | | | | | | | MIDI2 Set Tempo message defines the tempo in 10ns unit for finer accuracy, while MIDI1 was defined in 1us unit. For adapting this different unit, introduce "tempo_base" field to snd_seq_queue_tempo struct so that user-space can pass the proper tempo base unit. The accepted value is limited, it must be either 0, 10 or 1000. The protocol version is bumped to 1.0.4 along with this. The access with the older protocol version ignores the tempo-base value in ioctls and always treats as 1000.

* ALSA: seq: fix function cast warningsTakashi Iwai2024-02-132-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | clang-16 points out a control flow integrity (kcfi) issue when event callbacks get converted to incompatible types: sound/core/seq/seq_midi.c:135:30: error: cast from 'int (*)(struct snd_rawmidi_substream *, const char *, int)' to 'snd_seq_dump_func_t' (aka 'int (*)(void *, void *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] 135 | snd_seq_dump_var_event(ev, (snd_seq_dump_func_t)dump_midi, substream); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sound/core/seq/seq_virmidi.c:83:31: error: cast from 'int (*)(struct snd_rawmidi_substream *, const unsigned char *, int)' to 'snd_seq_dump_func_t' (aka 'int (*)(void *, void *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] 83 | snd_seq_dump_var_event(ev, (snd_seq_dump_func_t)snd_rawmidi_receive, vmidi->substream); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For addressing those errors, introduce wrapper functions that are used for callbacks and bridge to the actual function call with pointer cast.

* ALSA: seq: fix kvmalloc_array() arguments orderDmitry Antipov2023-12-291-1/+2
| | | | | | | | | | | | | | | | | | | When compiling with gcc version 14.0.0 20231220 (experimental) and W=1, I've noticed the following warning: sound/core/seq/seq_memory.c: In function 'snd_seq_pool_init': sound/core/seq/seq_memory.c:445:41: warning: 'kvmalloc_array' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args] 445 | cellptr = kvmalloc_array(sizeof(struct snd_seq_event_cell), pool->size, | ^~~~~~ Since 'n' and 'size' arguments of 'kvmalloc_array()' are multiplied to calculate the final size, their actual order doesn't affect the result and so this is not a bug. But it's still worth to fix it.

| | | | | | | | | | | | The compile warnings with -Wformat-truncation appearing at snd_seq_midisynth_probe() in seq_midi.c are false-positive; those must fit within the given string size. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.

* ALSA: seq: Avoid delivery of events for disabled UMP groupsTakashi Iwai2023-09-122-0/+24
| | | | | | | | | | | | | | | | | | | ALSA sequencer core still delivers events to the disabled UMP Group, leaving this handling to the device. But it's rather risky and it's easy to imagine that such an unexpected event may screw up the device firmware. This patch avoids the superfluous event deliveries by setting the group_filter of the UMP client as default, and evaluate the group_filter properly at delivery from non-UMP clients. The grouop_filter is updated upon the dynamic UMP Function Block updates, so that it follows the change of the disabled UMP Groups, too. Fixes: d2b706077792 ("ALSA: seq: Add UMP group filter") Link: https://lore.kernel.org/r/20230912085144.32534-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
