Jordan Rife 907a380eb3 net: prevent address rewrite in kernel_bind() ... commit c889a99a21bf124c3db08d09df919f0eccc5ea4c upstream. 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 1) Makes a copy of the bind address in kernel_bind() to insulate callers. 2) Replaces direct calls to sock->ops->bind() in net with kernel_bind() Link: https://lore.kernel.org/netdev/20230912013332.2048422-1-jrife@google.com/ Fixes: 4fbac77d2d ("bpf: Hooks for sys_bind") Cc: stable@vger.kernel.org Reviewed-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Jordan Rife <jrife@google.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.
