Use strlcat() to append a string to the previously created first part. The semantic match that finds this kind of problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression dev; expression phys; expression str; expression size; @@ usb_make_path(dev, phys, size); - strlcpy(phys, str, size); + strlcat(phys, str, size); // </smpl> Signed-off-by:

Error handling code following a kzalloc should free the allocated data. Similarly for usb-alloc urb.

All read transactions initiated by firedtv are only quadlet-sized, hence the backend->read call can be simplified a little. Signed-off-by:

Packet DMA buffers are queued either initially all at once (then, a queueing failure will cause firedtv to release the DMA context as a whole) or subsequently one by one as they recycled after use (then a failure is extremely unlikely). Therefore we can be a little less cautious when counting at which packet buffer to set the interrupt flag. Signed-off-by:

Cache only addresses of whole pages, not of each buffer chunk. Besides, page addresses can be obtained by page_address() instead of kmap() since they were allocated in lowmem. Signed-off-by:

The firedtv DVB driver will now work not only on top of the old ieee1394 driver stack but also on the new firewire driver stack. Alongside to the firedtv-1394.c backend for driver binding and I/O, the firedtv-fw.c backend is added. Depending on which of the two 1394 stacks is configured, one or the other or both backends will be built into the firedtv driver. This has been tested with a DVB-T and a DVB-C box on x86-64 and x86-32 together with a few different controllers (Agere FW323, a NEC chip, TI TSB82AA2, TSB43AB22/A, VIA VT6306). Signed-off-by:

Add #include <dvb_demux.h> for dvb_dmx_swfilter_packets(). This was already indirectly included via firedtv.h, but don't rely on it. The 4 bytes which were referred to as FIREWIRE_HEADER_SIZE are actually the source packet header from IEC 61883-4 (MPEG2-TS data transmission over 1394), not e.g. the IEEE 1394 isochronous packet header. So choose a more precise name. Also, express the payload size as a preprocessor constant too. Signed-off-by:

This initialization of the value of audio_mode is the one used if nothing matches in the subsequent switch. The variable audio_mode is subsequently assigned to constants such as TUNER_AUDIO_MONO and TUNER_AUDIO_STEREO. TUNER_AUDIO_STEREO has the same value as V4L2_TUNER_MODE_STEREO, so it would seem better to use that value here. Signed-off-by:

In driver ./drivers/media/video/usbvideo/quickcam_messenger.c in line 91: 91 usb_make_path(dev, cam->input_physname, sizeof(cam->input_physname)); After this line we use strncat: 92 strncat(cam->input_physname, "/input0", sizeof(cam->input_physname)); where sizeof(cam->input_physname) returns length of cam->input_phisname without length for null-symbol. But this parameter must be - "maximum numbers of bytes to copy", i.e.: sizeof(cam->input_physname)-strlen(cam->input_physname)-1. In this case, after call to usb_make_path the similar drivers use strlcat. Like in: drivers/hid/usbhid/hid-core.c: 1152 usb_make_path(dev, hid->phys, sizeof(hid->phys)); 1153 strlcat(hid->phys, "/input", sizeof(hid->phys)); Found by Linux Driver Verification Project. Use strlcat instead of strncat. Signed-off-by:
