Hi, I'm working on a FUSE filesystem to browse and access SMB networks. I'm using libsmb2 for that. It's not online yet, but my software is here: https://github.com/stefbon/OSNS Now I found out that smb2/3 do not support posix like file attributes, but do (almost?) everything with acl's. Now I see the function parse_dacl in fs/cifs/cifsacl.c, which determines the permissions from the acl. I see also that when there are no acl's, the default is 0777. I made the same choice in my filesystem. I've got some questions: a. what does the sid_unix_NFS_mode stand for? Is it part of the "unix extensions module for Windows"? b. can you assume some order in the acl's, so you participate on that? I want to know there are optimizations possible. Thanks in advance, Stef Bon
