Supersedes fork-headed PR #723. This replacement keeps the same head commit (
5eb8da36131ab7523dcf61de6168930a4eec79eb) but moves the PR head onto anAutomattic/kandelobranch.Why this is needed
PHP filesystem tests cover ownership and symlink edge cases, including
lchown. The host syscall path needs the target path in the syscall channel; otherwise the kernel cannot apply ownership operations to the intended pathname.Why this shape makes sense
The bug is in syscall marshalling, not PHP. Fixing the path transport keeps the syscall ABI coherent for every runtime caller that needs path-based ownership operations.
Why this is the correct fix
Marshalling the
lchownpath through the syscall channel preserves the user/kernel contract and lets the existing syscall implementation operate on the correct object.Verification
Branch-location correction only; replacement head SHA matches #723 exactly.
