2007-10-05 V4L: videobuf-core.c avoid NULL dereferences in videobuf-coreMauro Carvalho Chehab
From: Brandon Philips <bphilips@suse.de> The return value of videobuf_alloc() is unchecked but this function will return NULL on an error. Check for NULL and make videobuf_reqbufs() return the number of successfully allocated buffers. Also, fix saa7146_video.c and bttv-driver.c to use this returned buffer count.

2007-10-08videobuf_core init always require callback implementationMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> In the past, videobuf_queue_init were used to initialize PCI DMA videobuffers. This patch renames it, to avoid confusion with the previous kernel API, doing: s/videobuf_queue_init/void videobuf_queue_core_init/ Also, the operations is now part of the function parameter. The function will also add a test if this is defined, otherwise producing BUG. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-08Fix: avoid oops on some SMP machinesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This workaround fix a bug that happens on some SMP machines. On those machines, videobuf_iolock is called too soon, before file .mmap handler. This patch calls the scheduler before iolocking, allowing it to properly call the pending mmap. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-04cx23885: Update to new videobuf codeTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> cx23885 was still uses the old video-buf includes and code, which would only `work' if one happened to be compiling against a kernel that had the old headers. Even then, it wouldn't actually work, it would just compile without errors. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-10-04videobuf: Remove references to old Kconfig option nameTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB. But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB. It's clearly just leftover from when the file was obvious copied from the cx88 driver (which is not mentioned in the copyright BTW). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

The "resource" locking in vivi isn't needed since streamon/streamoff/read_stream do mutual exclusion using q->reading/q->streaming. Plus it is sort of broken: a) res_locked() use in vivi_read() is racey. b) res_free() calls mutex_lock twice causing streamoff to break Signed-off-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

videobuf_qbuf takes q->lock, and then calls q->ops->buf_prepare which by design in all drivers calls videobuf_iolock which calls videobuf_dma_init_user and this takes current->mm->mmap_sem on the other hand if user calls mumap from other thread, sys_munmap takes current->mm->mmap_sem and videobuf_vm_close takes q->lock Since this can occur only for V4L2_MEMORY_MMAP buffers, take current->mm->mmap_sem in qbuf, before q->lock, and don't take current->mm->mmap_sem videobuf_dma_init_user for those buffers Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org> http://thread.gmane.org/gmane.comp.video.video4linux/34978/focus=34981 Reviewed-by: Ricardo Cerqueira <v4l@cerqueira.org>
