Pull networking fixes from David Miller: 1) Make sure SKB control block is in the proper state during IPSEC ESP-in-TCP encapsulation. From Sabrina Dubroca. 2) Various kinds of attributes were not being cloned properly when we build new xfrm_state objects from existing ones. Fix from Antony Antony. 3) Make sure to keep BTF sections, from Tony Ambardar. 4) TX DMA channels need proper locking in lantiq driver, from Hauke Mehrtens. 5) Honour route MTU during forwarding, always. From Maciej Żenczykowski. 6) Fix races in kTLS which can result in crashes, from Rohit Maheshwari. 7) Skip TCP DSACKs with rediculous sequence ranges, from Priyaranjan Jha. 8) Use correct address family in xfrm state lookups, from Herbert Xu. 9) A bridge FDB flush should not clear out user managed fdb entries with the ext_learn flag set, from Nikolay Aleksandrov. 10) Fix nested locking of netdev address lists, from Taehee Yoo. 11) Fix handling of 32-bit DATA_FIN values in mptcp, from Mat Martineau. 12) Fix r8169 data corruptions on RTL8402 chips, from Heiner Kallweit. 13) Don't free command entries in mlx5 while comp handler could still be running, from Eran Ben Elisha. 14) Error flow of request_irq() in mlx5 is busted, due to an off by one we try to free and IRQ never allocated. From Maor Gottlieb. 15) Fix leak when dumping netlink policies, from Johannes Berg. 16) Sendpage cannot be performed when a page is a slab page, or the page count is < 1. Some subsystems such as nvme were doing so.

The current binding for the RPi firmware uses the simple-bus compatible as a fallback to benefit from its automatic probing of child nodes. However, simple-bus also comes with some constraints, like having the ranges, our case. Let's switch to simple-mfd that provides the same probing logic without those constraints.

2020-09-24gpio/aspeed-sgpio: enable access to all 80 input & output sgpiosJeremy Kerr
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines, corresponding to the 80 status bits available in hardware. Each of these lines can be configured as either an input or an output. However, each of these GPIOs is actually an input *and* an output; we actually have 80 inputs plus 80 outputs. This change expands the maximum number of GPIOs to 160; the lower half of this range are the input-only GPIOs, the upper half are the outputs. We fix the GPIO directions to correspond to this mapping. This also fixes a bug when setting GPIOs - we were reading from the input register, making it impossible to set more than one output GPIO.

2020-09-17ethtool: add and use message type for tunnel info replyMichal Kubecek
Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have. This is a problem because we are using two separate enums for userspace to kernel and kernel to userspace message types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for kernel to userspace messages. As the tunnel info request reached mainline in 5.9 merge window, we should still be able to fix the reply message type without breaking backward compatibility.

The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.
