Diagnostic Logs

I'm almost certain this error stems from a kernel bug. Below is my diagnostic process for reference:

1. Through extensive trial and error, I discovered the following rules in the ip rule command:

1:      from all ipproto tcp lookup 127
1:      from all ipproto udp lookup 127

This is abnormal. My tests confirmed that removing these entries suppresses the error, allowing VSCode to successfully connect to the WSL host.

2. Using the command ip route show table 127 to inspect the 127 table, I found:

127.0.0.1 via 169.254.73.152 dev loopback0 proto kernel src 127.0.0.1 onlink

This is the root cause of the error. Packets sent by the Windows VSCode client are intercepted by this rule and redirected to loopback0, preventing them from being forwarded to the local table according to standard routing rules:

local 127.0.0.1 dev lo proto kernel scope host src 127.0.0.1

3. The behavior in the local table is correct, while the behavior in the 127 table is incorrect. I want to point out that loopback0 is not the same as lo. After packets are intercepted by the table 127 rule, they are sent to loopback0, which does not forward packets to lo. By examining the journal logs, I found the following entries:

kernel: hv_netvsc fc232fd7-4443-4791-a539-deef713ec4d4 loopback0: renamed from eth4

This means: loopback0 is eth4. Furthermore, my testing confirmed that sudo ip link set eth4 up does not resolve the issue, meaning eth4 absolutely does not forward packets to lo. Since this entry appears in the kernel, I am almost certain this is a kernel bug.

PS: This issue is not a bug in VSCode, as I attempted to connect to a project within WSL using JetBrains. While their IDE successfully opened the project, all tools requiring connection to 127.0.0.1 (such as PyCharm's Python console) failed to function properly, reporting connection errors.
