2009-01-06Check fops_get() return valueLaurent Pinchart1-0/+4
Several subsystem open handlers dereference the fops_get() return value without checking it for nullness. This opens a race condition between the open handler and module unloading. A module can be marked as being unloaded (MODULE_STATE_GOING) before its exit function is called and gets the chance to unregister the driver. During that window open handlers can still be called, and fops_get() will fail in try_module_get() and return a NULL pointer. This change checks the fops_get() return value and returns -ENODEV if NULL.

2008-11-01saner FASYNC handling on file closeAl Viro4-4/+4
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-08-29sound: make OSS sound core optionalTejun Heo1-0/+1
sound/sound_core.c implements soundcore.ko and contains two parts - sound_class which is shared by both ALSA and OSS and device redirection support for OSS. It's always compiled when any sound support is enabled although it's necessary only when OSS (the actual one or emulation) is enabled. This is slightly wasteful and as device redirection always registers character device region for major 14, it prevents alternative implementation. This patch introduces a new config SOUND_OSS_CORE which is selected iff OSS support is actually necessary and build the OSS core part conditionally. If OSS is disabled, soundcore merely contains sound_class but leaving it that way seems to be the simplest approach as otherwise sound_class should be in ALSA core file if OSS is disabled but should be in soundcore if OSS is enabled. Also, there's also the user confusion factor. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-08-25ALSA: Allocate larger pages in sgbufTakashi Iwai2-16/+72
Most hardwares have limited buffer-descriptor table length. This also restricts the max buffer size of the sound driver. For example, snd-hda-intel has 1MB buffer size limit, and this is because it can have at most 256 BDL entries. For supporting larger buffers, we need to allocate larger pages even for sg-buffers. This patch changes the sgbuf allocation code to try to allocate larger pages first. At each head of the allocated pages, the number of allocated pages is stored in the lowest bits of the corresponding entry of the table addr field. This change isn't visible as long as the driver uses snd_sgbuf_get_addr() helper. Also, the patch adds a new function, snd_pcm_sgbuf_get_chunk_size(). This returns the size of the chunk on continuous pages starting at the given position offset. If the chunk reaches to a non-continuous page, it returns the size to the boundary.
