2022-05-17xfrm: set dst dev to blackhole_netdev instead of loopback_dev in ifdownXin Long1-1/+1
The global blackhole_netdev has replaced pernet loopback_dev to become the one given to the object that holds an netdev when ifdown in many places of ipv4 and ipv6 since commit 8d7017fd621d ("blackhole_netdev: use blackhole_netdev to invalidate dst entries"). Especially after commit faab39f63c1f ("net: allow out-of-order netdev unregistration"), it's no longer safe to use loopback_dev that may be freed before other netdev. This patch is to set dst dev to blackhole_netdev instead of loopback_dev in ifdown. v1->v2: - add Fixes tag as Eric suggested.

2022-05-17arm64: lds: move special code sections out of kernel exec segmentArd Biesheuvel1-9/+12
There are a few code sections that are emitted into the kernel's executable .text segment simply because they contain code, but are actually never executed via this mapping, so they can happily live in a region that gets mapped without executable permissions, reducing the risk of being gadgetized. Note that the kexec and hibernate region contents are always copied into a fresh page, and so there is no need to align them as long as the overall size of each is below 4 KiB.

2022-05-17media: hantro: Add H.264 field decoding supportNicolas Dufresne2-14/+110
This adds the required code to support field decoding. While most of the code is derived from Rockchip and VSI reference code, the reduction of the reference list to 16 entries was found by trial and errors. The list consists of all the references with the opposite field parity. The strategy is to deduplicate the reference picture that points to the same storage (same index). The choice of opposite parity has been made to keep the other field of the current field pair in the list. This method may not be robust if a field was lost.

The width and height in macroblocks is currently configured based on OUTPUT buffer resolution, this works for frame pictures but can cause issues for field pictures. When frame_mbs_only_flag is 0 the height in mbs should be height of the field instead of height of frame. Validate pic_width_in_mbs_minus1 and pic_height_in_map_units_minus1 against OUTPUT buffer resolution and use these values to configure HW. The validation is happening in both try_ctrt() and start() since it is otherwise possible to trick the driver during initialization by changing the OUTPUT format after having set a valid control.

2022-05-17media: rkvdec: Stop overclocking the decoderNicolas Dufresne1-6/+0
While this overclock hack seems to work on some implementations (some ChromeBooks, RockPi4) it also causes instability on other implementations (notably LibreComputer Renegade, but there were more reports in the LibreELEC project, where this has been removed). While performance is indeed affected (tested with GStreamer), 4K playback still works as long as you don't operate in lock step and keep at least 1 frame ahead of time in the decode queue. After discussion with ChromeOS members, it would seem that their implementation indeed used to synchronously decode each frame, so this hack was simply compensating for their code being less efficient. In my opinion, this hack should not have been included upstream.

The following two scenarios were failing for lan966x. 1. If the port had the address X and then trying to assign the same address, then the HW was just removing this address because first it tries to learn new address and then delete the old one. As they are the same the HW remove it. 2. If the port eth0 was assigned the same address as one of the other ports eth1 then when assigning back the address to eth0 then the HW was deleting the address of eth1. The case 1. is fixed by checking if the port has already the same address while case 2. is fixed by checking if the address is used by any other port.
