Subject: Stable Backport: net: Avoid address overwrite in kernel_connect

Upstream Commit ID: 0bdf399342c5acbd817c9098b6c7ed21f1974312
Patchwork Link:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=0bdf399342c5
Requested Kernel Versions: 4.19, 5.4, 5.10, 5.15, 6.1, 6.4, 6.5

This patch addresses an incompatibility between eBPF connect4/connect6
programs and kernel space clients such as NFS. At present, the issue
this patch fixes is a blocker for users that want to combine NFS with
Cilium. The fix has been applied upstream but the same bug exists with
older kernels.
