-
- The traditional UNIX implementation of file permissions has
- been
-
- if owned by user
- check owner bits
- else if owned by user's group
- check group bits
- else
- check other bits
-
- Hence, if one owns a file *only* the owner bits matter. The group
- bits apply only to non-owners in the group; the other bits apply
- only to non-owner non-group. I don't know what 1003.1 says, though.
- Given its reliance on traditional UNIX, this is what I'd expect it
- to say.
-
- The other reasonable interpretation I can imagine is
-
- if (owned by user and owner bits allow access) or
- (owned by user's group and group bits allow access) or
- (other bits allow access)
- grant access
- else
- deny access
-
- I'd bet small amounts of money that this latter interpretation
- doesn't conform to 1003.1.
