NFS uses the unofficial fattr3 interface to fetch real stat(2) info from the remote FS, see https://cygwin.com/cgit/newlib-cygwin/tree/winsup/cygwin/local_includes/nfs.h https://cygwin.com/cgit/newlib-cygwin/tree/winsup/cygwin/nfs.cc#n19 > I'm also asking because the ms-nfs41-client Windows NFSv4.1 driver now > has ACL support (like the Exceed NFSv4 driver), but it would be > frustrating if Cygwin just turns this off. Cygwin "doesn't turn them off". Cygwin recognizes the filesystem as being an NFS filesystem and uses special non-Windowsy access methods provided by the MS_NFS client. If you want ACL support for the NFSv4 client, I made a couple of suggestions how to integrate stuff in Cygwin in November: https://cygwin.com/pipermail/cygwin-developers/2023-November/012692.html Corinna -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
