alexcrichton opened PR #7926 from alexcrichton:fix-proxy-adapter-fs-interaction to bytecodealliance:main:

This commit fixes an issue with the proxy adapter where if the proxy program attempted to look at prestat items, which wasi-libc always does on startup, it would invoke fd_prestat_get and receive ERRNO_NOTSUP in response (the standard response when using the
cfg_filesystem_available! macro). This error code is unexpected by wasi-libc and causes wasi-libc to abort. The PR here is to instead return ERRNO_BADF which is indeed expected by wasi-libc and is recognized as meaning "that prestat isn't available".
