* staging: rtl8723bs: Remove unneeded goto statementsLarry Finger2020-02-101-35/+12
| | | | | | | | | | | | | In routines rtw_hostapd_ioctl() and wpa_supplicant_ioctl(), several error conditions involve setting a variable indicating the error, followed by a goto. The code following the target of that goto merely returns the value. It is simpler, therefore to return the error value immediately, and eliminate the got target.

* staging: rtl8723bs: Fix potential overuse of kernel memoryLarry Finger2020-02-101-1/+1
| | | | | | | | | | | | | | | | In routine wpa_supplicant_ioctl(), the user-controlled p->length is checked to be at least the size of struct ieee_param size, but the code does not detect the case where p->length is greater than the size of the struct, thus a malicious user could be wasting kernel memory.

* staging: rtl8723bs: Fix potential security holeLarry Finger2020-02-101-1/+1
| | | | | | | | | | | | | | | | | | In routine rtw_hostapd_ioctl(), the user-controlled p->length is assumed to be at least the size of struct ieee_param size, but this assumption is never checked. This could result in out-of-bounds read/write on kernel heap in case a p->length less than the size of struct ieee_param is specified by the user. If p->length is allowed to be greater than the size of the struct, then a malicious user could be wasting kernel memory. Fixes commit 554c0a3abf216 ("0taging: Add rtl8723bs sdio wifi driver").

* staging: android: ashmem: Disallow ashmem memory from being remappedSuren Baghdasaryan2020-02-101-0/+28
| | | | | | | | | | | | | | | | When ashmem file is mmapped, the resulting vma->vm_file points to the backing shmem file with the generic fops that do not check ashmem permissions like fops of ashmem do. If an mremap is done on the ashmem region, then the permission checks will be skipped. Fix that by disallowing mapping operation on the backing shmem file.

| * media: cedrus: Fix decoding for some HEVC videosJernej Skrabec2020-01-092-3/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems that for some HEVC videos at least one bitstream parsing trigger must be called in order to be decoded correctly. There is no explanation why this helps, but it was observed that several videos with this fix are now decoded correctly and there is no regression with others. Without this fix, those same videos totally crash HEVC decoder (other decoder engines are unaffected). After decoding those problematic videos, HEVC decoder always returns only green image (all zeros). Only complete HW reset helps. This fix is similar to that for H264.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the imgu running mode need user to set by v4l2 ctrl. However, imgu only support 2 pipes and 2 operation modes - video and still. This patch make the first imgu subdev running as video and second one running as still, it will make the user understand easily, it can also cover current camera use cases requirement. The running mode is set during subdev registering, no race-condition after change, so it is safe to change the mode data type to integer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hantro G1 decoder is able to enable a post-processor on the decoding pipeline, which can be used to perform scaling and color conversion. The post-processor is integrated to the decoder, and it's possible to use it in a way that is completely transparent to the user. This commit enables color conversion via post-processing, which means the driver now exposes YUV packed, in addition to NV12.

By fixing this this patch prevents a kernel crash when removing the configuration directory of a link that already has been destroyed.
