* Expand the use of stat(2) flags to allow storing some Windows/DOSken2013-08-211-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and CIFS file attributes as BSD stat(2) flags. This work is intended to be compatible with ZFS, the Solaris CIFS server's interaction with ZFS, somewhat compatible with MacOS X, and of course compatible with Windows. The Windows attributes that are implemented were chosen based on the attributes that ZFS already supports. The summary of the flags is as follows: UF_SYSTEM: Command line name: "system" or "usystem" ZFS name: XAT_SYSTEM, ZFS_SYSTEM Windows: FILE_ATTRIBUTE_SYSTEM This flag means that the file is used by the operating system. FreeBSD does not enforce any special handling when this flag is set. UF_SPARSE: Command line name: "sparse" or "usparse" ZFS name: XAT_SPARSE, ZFS_SPARSE Windows: FILE_ATTRIBUTE_SPARSE_FILE This flag means that the file is sparse. Although ZFS may modify this in some situations, there is not generally any special handling for this flag. UF_OFFLINE: Command line name: "offline" or "uoffline" ZFS name: XAT_OFFLINE, ZFS_OFFLINE Windows: FILE_ATTRIBUTE_OFFLINE This flag means that the file has been moved to offline storage. FreeBSD does not have any special handling for this flag. UF_REPARSE: Command line name: "reparse" or "ureparse" ZFS name: XAT_REPARSE, ZFS_REPARSE Windows: FILE_ATTRIBUTE_REPARSE_POINT This flag means that the file is a Windows reparse point. ZFS has special handling code for reparse points, but we don't currently have the other supporting infrastructure for them. UF_HIDDEN: Command line name: "hidden" or "uhidden" ZFS name: XAT_HIDDEN, ZFS_HIDDEN Windows: FILE_ATTRIBUTE_HIDDEN This flag means that the file may be excluded from a directory listing if the application honors it. FreeBSD has no special handling for this flag. The name and bit definition for UF_HIDDEN are identical to the definition in MacOS X. UF_READONLY: Command line name: "urdonly", "rdonly", "readonly" ZFS name: XAT_READONLY, ZFS_READONLY Windows: FILE_ATTRIBUTE_READONLY This flag means that the file may not written or appended, but its attributes may be changed. ZFS currently enforces this flag, but Illumos developers have discussed disabling enforcement. The behavior of this flag is different than MacOS X. MacOS X uses UF_IMMUTABLE to represent the DOS readonly permission, but that flag has a stronger meaning than the semantics of DOS readonly permissions. UF_ARCHIVE: Command line name: "uarch", "uarchive" ZFS_NAME: XAT_ARCHIVE, ZFS_ARCHIVE Windows name: FILE_ATTRIBUTE_ARCHIVE The UF_ARCHIVED flag means that the file has changed and needs to be archived. The meaning is same as the Windows FILE_ATTRIBUTE_ARCHIVE attribute, and the ZFS XAT_ARCHIVE and ZFS_ARCHIVE attribute. msdosfs and ZFS have special handling for this flag. i.e. they will set it when the file changes. sys/param.h: Bump __FreeBSD_version to 1000047 for the addition of new stat(2) flags. chflags.1: Document the new command line flag names (e.g. "system", "hidden") available to the user. ls.1: Reference chflags(1) for a list of file flags and their meanings. strtofflags.c: Implement the mapping between the new command line flag names and new stat(2) flags. chflags.2: Document all of the new stat(2) flags, and explain the intended behavior in a little more detail. Explain how they map to Windows file attributes. Different filesystems behave differently with respect to flags, so warn the application developer to take care when using them. zfs_vnops.c: Add support for getting and setting the UF_ARCHIVE, UF_READONLY, UF_SYSTEM, UF_HIDDEN, UF_REPARSE, UF_OFFLINE, and UF_SPARSE flags. All of these flags are implemented using attributes that ZFS already supports, so the on-disk format has not changed. ZFS currently doesn't allow setting the UF_REPARSE flag, and we don't really have the other infrastructure to support reparse points. msdosfs_denode.c, msdosfs_vnops.c: Add support for getting and setting UF_HIDDEN, UF_SYSTEM and UF_READONLY in MSDOSFS. It supported SF_ARCHIVED, but this has been changed to be UF_ARCHIVE, which has the same semantics as the DOS archive attribute instead of inverse semantics like SF_ARCHIVED. After discussion with Bruce Evans, change several things in the msdosfs behavior: Use UF_READONLY to indicate whether a file is writeable instead of file permissions, but don't actually enforce it. Refuse to change attributes on the root directory, because it is special in FAT filesystems, but allow most other attribute changes on directories. Don't set the archive attribute on a directory when its modification time is updated. Windows and DOS don't set the archive attribute in that scenario, so we are now bug-for-bug compatible. smbfs_node.c, smbfs_vnops.c: Add support for UF_HIDDEN, UF_SYSTEM, UF_READONLY and UF_ARCHIVE in SMBFS. This is similar to changes that Apple has made in their version of SMBFS (as of smb-583.8, posted on opensource.apple.com), but not quite the same. We map SMB_FA_READONLY to UF_READONLY, because UF_READONLY is intended to match the semantics of the DOS readonly flag. The MacOS X code maps both UF_IMMUTABLE and SF_IMMUTABLE to SMB_FA_READONLY, but the immutable flags have stronger meaning than the DOS readonly bit. stat.h: Add definitions for UF_SYSTEM, UF_SPARSE, UF_OFFLINE, UF_REPARSE, UF_ARCHIVE, UF_READONLY and UF_HIDDEN. The definition of UF_HIDDEN is the same as the MacOS X definition. Add commented-out definitions of UF_COMPRESSED and UF_TRACKED. They are defined in MacOS X (as of 10.8.2), but we do not implement them (yet). ufs_vnops.c: Add support for getting and setting UF_ARCHIVE, UF_HIDDEN, UF_OFFLINE, UF_READONLY, UF_REPARSE, UF_SPARSE, and UF_SYSTEM in UFS. Alphabetize the flags that are supported. These new flags are only stored, UFS does not take any action if the flag is set. Sponsored by: Spectra Logic Reviewed by: bde (earlier version)

| | | | | | | | | | | | | | | | | | | | | | | | | interface, and statically link them to the programs using them. These functions, upon reflection and discussion, are too generically named for a library interface with such specific functionality. Also the api that they use, whilst ok for private use, isn't good enough for a libc function. Additionally there were complications with the build/install-world process. It depends heavily upon xinstall, which got broken by the change in api, and caused bootstrap problems and general mayhem. There is work in progress to address future problems that may be caused by changes in install-chain tools, and better names for {g|s}etflags can be derived when some future program requires them. For now the code has been left in src/lib/libc/gen (it started off in src/bin/ls). It's important to provide library functions for manipulating file flag strings if we ever want this interface to be adopted outside of the source tree, but now isn't necessarily the right moment with 4.0-release just around the corner.

* Historically file flags (schg, uschg, etc) have been converted fromjoe2000-01-272-4/+1
| | | | | | | | | | | | | | | | | string to u_long and back using two functions, flags_to_string and string_to_flags, which co-existed with 'ls'. As time has progressed more and more other tools have used these private functions to manipulate the file flags. Recently I moved these functions from /usr/src/bin/ls to libutil, but after some discussion with bde it's been decided that they really ought to go in libc. There are two already existing libc functions for manipulating file modes: setmode and getmode. In keeping with these flags_to_string has been renamed getflags and string_to_flags to setflags. The manual page could probably be improved upon ;)
