Windows Version
Microsoft Windows [Version 10.0.26100.4061]
WSL Version
2.5.7.0
Are you using WSL 1 or WSL 2?
Kernel Version
6.6.87.1-1
Distro Version
Ubuntu 24.04
Other Software
wibo, version 0.6.16
Repro Steps
- Update to WSL 2.5.7.0
- Run wibo
Expected Behavior
- wibo should run wrapped executable
Actual Behavior
This was working previously with kernel 5.5, and also works when custom compiling 6.x kernel with CONFIG_MODIFY_LDT_SYSCALL re-enabled (was disabled in this commit)
With that said, this is a breaking change between kernel versions that was unexpected and not trivial to diagnose. Additionally resolving it requires custom compiling either a 5.x kernel which works by default, or a 6.x kernel with this flag enabled (since MS does not appear to have pre-built kernel bzImages available for older versions as far as I could tell)
