2022-05-24match the boundary type with kernel driverdvdli
1. Remove calculation of boundary and retrieve boundary from ALSA kernel. Also fix type when getting available and advance appl_ptr. 2. Fix avail in pcm_mmap_transfer getting overflow. 3. Fix typo.

Include time.h before asound.h to avoid the following build failure on musl that was already fixed a long time with https://github.com/tinyalsa/tinyalsa/commit/c8333f8c7a4e4b9549abeef7530b2cd20a18e537 but reappeared on version 2.0.0: In file included from ../src/pcm_hw.c:42: /home/peko/autobuild/instance-1/output-1/host/i586-buildroot-linux-musl/sysroot/usr/include/sound/asound.h:444:18: error: field 'trigger_tstamp' has incomplete type 444 | struct timespec trigger_tstamp; /* time when stream was started/stopped/paused */ | ^~~~~~~~~~~~~~ Fixes: - http://autobuild.buildroot.org/results/a75e23dc585bd071f4d65face5489ed6ac22edbe Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>

2021-11-02mixer: fix index underflow when index=0Caleb Connolly
In mixer_get_ctl_by_name_and_index(), the post-fix decrement means that the index will be decremented after the comparison, but before the return, leading to an unsigned integer underflow. This causes a crash on platforms with -fsanitize=integer enabled. Fix this by avoiding decrementing index until after the return. Change-Id: I25a17ced4185bdebd500285bd30b342b16b4ac12

2021-07-13fix the zero fd closing problemdvdli
The pcm_hw_close refused to close the zero fd. Add "equal to" condition and modify the type of fd to int to close the zero fd.
2021-06-02force pcm_open to open device with the non-blocking flagdvdli
When a client opens a PCM device whose substreams are all occupied without the non-blocking flag, the open function would be blocked in the kernel until the previous opened ones are closed. This would cause deadlock if they try to hold the same lock. Most of the ALSA PCM drivers on embedded systems are implemented with the ALSA SOC framework. Each PCM device has only one substream. This problem would happen frequently. To force pcm_open to open PCM devices with non-blocking flag is beneficial to resolve this problem. It returns the control to clients to try again later. The reason why we don't call pcm_open with PCM_NONBLOCK is that the PCM_NONBLOCK also affects the read and write behaviors. I also add a test case to test whether the pcm_open would be blocked.
2021-05-19remove range checking in mixer_ctl_set_valuedvdli
There are some drivers assigning wrong ranges of mixer control's values. Let ALSA drivers to check whether values are in ranges.

2021-01-12remove pcm_prepare in pcm_opendvdli
For the dynamic pcm device, it is valid to specify the backend after opening it. However, it is invalid to call prepare on a dynamic pcm device without connecting any backend device. We should not do pcm_prepare in pcm_open. See also: Issue #197

Backward compatible for pcm_write() pcm_read()
2020-11-01Backward compatible for pcm_write() pcm_read()Kui Wang
Current return value of pcm_write()/pcm_read() comes from pcm_writei()/pcm_readi() which is the actual frames written/read. But the old pcm_write() /pcm_read() just returns 0 on success and a nagative value on error. This change will keep the pcm_write()/pcm_read() as the old behavior which has been already used by many applications, and is also matching the comment above each function.

2020-10-29AOSP CL "pcm: Fix usage of oops() function for use of strerror."dvdli
https://android.googlesource.com/platform/external/tinyalsa/+/50028cd233f8cf8a084e950c951eefc01e1cd15c commit 50028cd233f8cf8a084e950c951eefc01e1cd15c author John Muir <muirj@google.com> pcm: Fix usage of oops() function for use of strerror. The oops() function expected errno to be passed in, but at some point it was broken to look at errno itself, and ignore the passed-in value. Fix the oops() function to check the passed-in value, and modify uses of oops() to actually pass in errno and not -errno or the return value from the errored function call. Bug: None Test: pcm error code printed correctly. Change-Id: I555e1eda0cdd0cc9b94e05423d341f1c08f8e485 (cherry picked from commit 2c1d902ace5f78dcff0c39740642d269b2e17dff) Note: the oops in pcm_mmap_transfer was removed.

2020-04-23tinyalsa: use strncpy instead of memcpy to copy string constantMinecrell
memcpy() is arguably wrong when copying these string constants. The string constants will usually just be as long as necessary, so we might copy some random memory behind it and eventually crash. Use strncpy() instead to avoid copying characters after the null terminator. For some reason the strings in snd_ctl_card_info use unsigned chars, so we need a cast to char* to make it compile unfortunately... This fixes the following compile error on ppc64le: In function 'mixer_plug_get_card_info', inlined from 'mixer_plug_ioctl' at mixer_plugin.c:371:15: mixer_plugin.c:333:5: error: 'memcpy' forming offset [9, 16] is out of the bounds [0, 8] [-Werror=array-bounds] 333 | memcpy(card_info->id, "card_id", sizeof(card_info->id)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Not sure why that warning does not exist on other architectures.
