Usage count = 1 This is fixed upstream with commit b87b04f5019e ("ipv4: Fix device used for dst_alloc with local routes"), included in linux v5.13. The original patch, which has introduced the bug, is included in linux v4.10. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b87b04f5019e [Test Case] The upstream patch includes a test case, which describe how to reproduce the bug. [Regression Potential] The patch affects ipv4 routing. It is straightforward, it links new dst to a vrf device instead of the loopback if needed.
