Similar to the change in commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect"), BPF hooks run on bind may rewrite the address passed to kernel_bind(). This change
- Makes a copy of the bind address in kernel_bind() to insulate callers.
- Replaces direct calls to sock->ops->bind() with kernel_bind()

I fear this is going to cause a few conflicts with other trees. We can still take it, but at very least we will need some acks from the relevant maintainers.
I *think* it would be easier split this and patch 1/3 in individual patches targeting the different trees, hopefully not many additional patches will be required. What do you think?
