| H A D | cloudabi_file.c | diff 285930 Tue Jul 28 04:48:37 MDT 2015 ed Make fstat() and friends work. Summary: CloudABI provides access to two different stat structures: - fdstat, containing file descriptor level status: oflags, file descriptor type and Capsicum rights, used by cap_rights_get(), fcntl(F_GETFL), getsockopt(SO_TYPE). - filestat, containing your regular file status: timestamps, inode number, used by fstat(). Unlike FreeBSD's stat::st_mode, CloudABI file descriptor types don't have overloaded meanings (e.g., returning S_ISCHR() for kqueues). Add a utility function to extract the type of a file descriptor accurately. CloudABI does not work with O_ACCMODEs. File descriptors have two sets of Capsicum-style rights: rights that apply to the file descriptor itself ('base') and rights that apply to any new file descriptors yielded through openat() ('inheriting'). Though not perfect, we can pretty safely decompose Capsicum rights to such a pair. This is done in convert_capabilities(). Test Plan: Tests for these system calls are fairly extensive in cloudlibc.
