Staging: rtl8723bs: prevent buffer overflow in update_sta_support_rate()

2020-06-16T19:25:38Z

The "ie_len" variable is in the 0-255 range and it comes from the network. If it's over NDIS_802_11_LENGTH_RATES_EX (16) then that will lead to memory corruption.

staging: wfx: fix coherency of hif_scan() prototype

2020-06-16T19:22:51Z

The function hif_scan() return the timeout for the completion of the scan request. It is the only function from hif_tx.c that return another thing than just an error code. This behavior is not coherent with the rest of file. Worse, if value returned is positive, the caller can't make say if it is a timeout or the value returned by the hardware. Uniformize API with other HIF functions, only return the error code and pass timeout with parameters.

staging: wfx: fix AC priority

2020-06-16T19:22:50Z

In order to work properly all the queues of the device must be filled (the device chooses itself the queue to use depending of AC parameters and other things). It is the job of wfx_tx_queues_get_skb() to choose which queue must be filled. However, the sorting algorithm was inverted, so it prioritized the already filled queue! Consequently, the AC priorities was badly broken.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

media: rkvdec: Fix H264 scaling list order

2020-06-11T17:21:38Z

The Rockchip Video Decoder driver is expecting that the values in a scaling list are in zig-zag order and applies the inverse scanning process to get the values in matrix order. Commit 0b0393d59eb4 ("media: uapi: h264: clarify expected scaling_list_4x4/8x8 order") clarified that the values in the scaling list should already be in matrix order. Fix this by removing the reordering and change to use two memcpy.

media: cedrus: Program output format during each run

2020-06-11T17:18:37Z

Previously, the output format was programmed as part of the ioctl() handler. However, this has two problems: 1) If there are multiple active streams with different output formats, the hardware will use whichever format was set last for both streams. Similarly, an ioctl() done in an inactive context will wrongly affect other active contexts. 2) The registers are written while the device is not actively streaming. To enable runtime PM tied to the streaming state, all hardware access needs to be moved inside cedrus_device_run(). The call to cedrus_dst_format_set() is now placed just before the codec-specific callback that programs the hardware.
