Because of u32 type being used to store pixel clock rate, expression used to calculate pipeline clocks (pixel_clock * bpp) produces wrong value due to integer overflow. This patch changes data type used to store, pass and retrieve pixel_clock from u32 to u64 to make this mistake less likely to be repeated in the future. Signed-off-by:

There are places in the camss driver where camss_get_pixel_clock() is called to get the pixel rate (using V4L2_CID_PIXEL_RATE control) and to calculate the link frequency from it. There is a case when this would not work: when V4L2_CID_PIXEL_RATE gets the rate at which the pixels are read (sampled) from the sensor's pixel array, and this rate is different from the pixel transmission rate over the CSI link, the link frequency value can't be calculated from the pixel rate. One needs to use V4L2_CID_LINK_FREQ to get the link frequency in this case. Replace such calls to camss_get_pixel_clock() with calls to a wrapper around v4l2_get_link_freq(). v4l2_get_link_freq() tries V4L2_CID_LINK_FREQ first, and if it is not implemented by the camera sensor driver, falls back to V4L2_CID_PIXEL_RATE to calculate the link frequency value from. Calls to camss_get_pixel_clock() from vfe_[check,set]_clock_rates() are left intact as it looks like this VFE clock does depend on the rate the pixel samples comes out of the camera sensor, not on the frequency at which the link between the sensor and the CSI receiver operates.

As some hardware have a knob to enable or disable emulation prevention bytes removal, driver writers ended up wondering what exactly the START_CODE_NONE modes meant in this regards. This patch clarify what is expected with a reference to the specification. Reported-by:

Constify two static structs which are never modified to allow the compiler to put them in read-only memory. The only usage of norm_params is only read from it in usbtv_configure_for_norm(). Making it const shrinks the resulting ko-file with 300 bytes (tested with gcc 10). The only usage of usbtv_ioctl_ops is to put its address to the ioctl_ops field in the video_device struct. Making it const moves ~1kb to read-only memory. Signed-off-by:

dvb_usb_device_init() copies the properties to the own data, so that the callers can release the original properties later (as done in the commit 299c7007 ("media: dw2102: Fix memleak on sequence of probes")). However, it also stores dev->desc pointer that is a reference to the original properties data. Since dev->desc is referred later, it may result in use-after-free, in the worst case, leading to a kernel Oops as reported. This patch addresses the problem by allocating and copying the properties at first, then get the desc from the copied properties. Reported-and-tested-by:

dvb_usb_device_init() allocates a dvb_usb_device object, but it doesn't release the object by itself even at errors. The object is released in the callee side (dvb_usb_init()) in some error cases via dvb_usb_exit() call, but it also missed the object free in other error paths. And, the caller (it's only dvb_usb_device_init()) doesn't seem caring the resource management as well, hence those memories are leaked. This patch assures releasing the memory at the error path in dvb_usb_device_init(). Now dvb_usb_init() frees the resources it allocated but leaves the passed dvb_usb_device object intact. In turn, the dvb_usb_device object is released in dvb_usb_device_init() instead. We could use dvb_usb_exit() function for releasing everything in the callee (as it was used for some error cases in the original code), but releasing the passed object in the callee is non-intuitive and error-prone. So I took this approach (which is more standard in Linus kernel code) although it ended with a bit more open codes. Along with the change, the patch makes sure that USB intfdata is reset and don't return the bogus pointer to the caller of dvb_usb_device_init() at the error path, too.

The Picture Parameter Set Flags table for H-264 doesn't output well on PDF. There are missing format instructions for LaTeX, and the columns are too long.

Sphinx/LaTeX doesn't work well with literal blocks. Due to that, V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF ends being writing outside the table (and even outside the page). We need to not only change the table size and font size, but also to change the message, in order to avoid this bug. So, improve the text a little bit, while ensuring that the literal will be written at the beginning of the second line. Signed-off-by: -

Instead of using "- 1", use "minus one". The reason is that, if the table is split like: V4L2_FWHT_FL_COMPONENTS_NUM_MSK 0x00070000 The number of color components - 1. One might not realize the meaning of the second line. As a side effect, using text instead of arabic numbers is more appropriate for formal documents like this spec. Signed-off-by: -

While fixing issues with PDF generation, I noticed that bit 8 was missing for WSS 625 format. While here, convert the literal block into a tables, as it becomes more visible. I opted to move the payload into a separate table, as Sphinx has troubles with complex nested tables. This way, it should work fine on both html and LaTeX/PDF formats. Signed-off-by:
