I'm announcing the release of the 5.9.13 kernel.
All users of the 5.9 kernel series must upgrade.
The updated 5.9.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.9.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

Assumptions:
- - if device has no dev->hard_header routine, it adds and removes ll header
- inside itself. In this case ll header is invisible outside of device,
- but higher levels still should reserve dev->hard_header_len.
- Some devices are enough clever to reallocate skb, when header
- will not fit to reserved space (tunnel), another ones are silly
- (PPP).
+ - If the device has no dev->header_ops->create, there is no LL header
+ visible above the device. In this case, its hard_header_len should be 0.
+ The device may prepend its own header internally. In this case, its
+ needed_headroom should be set to the space needed for it to add its
+ internal header.
+ For example, a WiFi driver pretending to be an Ethernet driver should
+ set its hard_header_len to be the Ethernet header length, and set its
+ needed_headroom to be (the real WiFi header length - the fake Ethernet
+ header length).
- packet socket receives packets with pulled ll header,
so that SOCK_RAW should push it back.

-Incoming, dev->hard_header==NULL
- mac_header -> UNKNOWN position. It is very likely, that it points to ll
- header. PPP makes it, that is wrong, because introduce
- assymetry between rx and tx paths.
+Incoming, dev_has_header(dev) == false

+ However drivers often make it point to the ll header.
+ This is incorrect because the ll header should be invisible to us.
