2007-09-27V4L: videobuf-core.c lock before streaming checkbphilips@suse.de
The reading/streaming fields are used for mutual exclusion of the queue and should be protected by the queue lock.

2007-09-27V4L: vivi.c remove the "resource" lockingbphilips@suse.de
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>
2007-09-27V4L: vivi.c replace logic in vivi_poll with videobuf_poll_streambphilips@suse.de

2007-09-27V4L: Fix a lock inversion in generic videobuf codeMaxim Levitsky
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>

2007-08-27Fix vivi poll() methodMauro Carvalho Chehab
Due to the replace of videobuf_read_one to videobuf_read_stream, poll() method implementation is wrong. This fixes poll() implementation, making read of /dev/video? to work again. With this method, an USB driver can use video-buf, without needing to request memory from the DMA-safe area. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-20 Fix VIDIOCGAP corruption in ivtvMauro Carvalho Chehab
From: Alan Cox <alan@lxorguk.ukuu.org.uk> Frank Bennett reported that ivtv was causing skype to crash. With help from one of their developers he showed it was a kernel problem. VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names that are too long and does not truncate them so corrupts a few bytes of the app data area. Possibly the names also want trimming but for now this should fix the corruption case.

2008-04-21tuner-xc2028: Several fixes to SCODEMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> This patch fixes several issues on SCODE: 1) The extracting tool weren't generating the proper tags for SCODE. This has almost no effect, since those tags shouldn't be used; 2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700; 3) seek_firmware were wanting an exact match for firmware type. This is wrong. As result, no SCODE firmware were loaded; 4) A few files were including the wrong file for seeking demod firmwares; 5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware. However, this weren't documentated. This feature require more testing. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
