Rather than adding a fchmodat2() syscall, should we add a "set_file_attrs()" syscall that takes a mask and allows you to set a bunch of stuff all in one go? Basically, an interface to notify_change() in the kernel that would allow several stats to be set atomically. This might be of particular interest to network filesystems.
Presumably looking something like statx(2) (except hopefully with extensible structs this time :P)? I think that could also be useful, but given this is a fairly straight-forward syscall addition (and it also would resolve the AT_EMPTY_PATH issue for chmod as well as simplify the glibc wrapper), I think it makes sense to take this and we can do set_statx(2) separately? -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
