| 2020-08-13 | ALSA: line6: Perform sanity check for each URB creation |   Takashi Iwai | |
| commit 6e8a914ad619042c5f25a4feb663357c4170fd8d upstream. LINE6 drivers create stream URBs with a fixed pipe without checking its validity, and this may lead to a kernel WARNING at the submission when a malformed USB descriptor is passed. For avoiding the kernel warning, perform the similar sanity checks for each pipe type at creating a URB.

| 2018-06-12 | treewide: kzalloc() -> kcalloc() |   Kees Cook | |
| The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

| 2015-01-28 | ALSA: line6: Reorganize PCM stream handling | Takashi Iwai | |
| The current code deals with the stream start / stop solely via line6_pcm_acquire() and line6_pcm_release(). This was (supposedly) intended to avoid the races, but it doesn't work as expected. The concurrent acquire and release calls can be performed without proper protections, thus this might result in memory corruption. Furthermore, we can't take a mutex to protect the whole function because it can be called from the PCM trigger callback that is an atomic context. Also spinlock isn't appropriate because the function allocates with kmalloc with GFP_KERNEL. That is, these function just lead to singular problems. This is an attempt to reduce the existing races. First off, separate both the stream buffer management and the stream URB management. The former is protected via a newly introduced state_mutex while the latter is protected via each line6_pcm_stream lock. Secondly, the stream state are now managed in opened and running bit flags of each line6_pcm_stream. Not only this a bit clearer than previous combined bit flags, this also gives a better abstraction. These rewrites allows us to make common hw_params and hw_free callbacks for both playback and capture directions. For the monitor and impulse operations, still line6_pcm_acquire() and line6_pcm_release() are used. They call internally the corresponding functions for both playback and capture streams with proper lock or mutex. Unlike the previous versions, these function don't take the bit masks but the only single type value. Also they are supposed to be applied only as duplex operations.

| 2015-01-28 | ALSA: line6: Clear prev_fbuf and prev_fsize properly | Takashi Iwai | |
| Clearing prev_fsize in line6_pcm_acquire() is pretty racy. This can be called at any time while the stream is being played. Rather better to clear prev_fbuf and prev_fsize at the proper place like the stream stop for capture, and just after copying the monitor / impulse data inside the spinlock.

This patch extends the range to protect via each stream's spinlock (now the whole submit_audio_*_urb() are covered), and take the capture stream lock additionally for the impulse and monitor handling part.

| 2015-01-20 | ALSA: line6: Reorganize card resource handling | Takashi Iwai | |
| This is a fairly big rewrite regarding the card resource management in line6 drivers: - The card creation is moved into line6_probe(). This adds the global destructor to private_free, so that each driver doesn't have to call it any longer. - The USB disconnect callback handles the card release, thus each driver needs to concentrate on only its own resources. No need to snd_card_*() call in the destructor. - Fix the potential stall in disconnection by removing snd_card_free(). It's replaced with snd_card_free_when_closed() for asynchronous release. - The only remaining operation for the card in each driver is the call of snd_card_register(). All the rest are dealt in the common module by itself. - These ended up with removal of audio.[ch] as a result of a reduction of one layer. Each driver just needs to call line6_probe().
