Volumes that support VolFS and can support Carbon File ID * references should set this bit. * * VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic * links. The symlink(), readlink(), and lstat() calls all use this * symbolic link. * * VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links. * The link() call creates hard links. * * VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting * a journal used to speed recovery in case of unplanned shutdown * (such as a power outage or crash). This bit does not necessarily * mean the volume is actively using a journal for recovery. * * VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using * a journal for use in speeding recovery after an unplanned shutdown. * This bit can be set only if VOL_CAP_FMT_JOURNAL is also set. * * VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not * store reliable times for the root directory, so you should not * depend on them to detect changes, etc. * * VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files. * That is, files which can have "holes" that have never been written * to, and are not allocated on disk. Sparse files may have an * allocated size that is less than the file's logical length. * * VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs) * that have never been written to must appear to contain zeroes. When * this bit is set, the volume keeps track of allocated but unwritten * runs of a file so that it can substitute zeroes without actually * writing zeroes to the media. This provides performance similar to * sparse files, but not the space savings. * * VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are * case sensitive (upper and lower case are different). When clear, * an upper case character is equivalent to a lower case character, * and you can't have two names that differ solely in the case of * the characters. * * VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names * preserve the difference between upper and lower case. If clear, * the volume may change the case of some characters (typically * making them all upper or all lower case). A volume that sets * VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING. * * VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers * (especially Carbon) that statfs() is fast enough that its results * need not be cached by those upper layers. A volume that caches * the statfs information in its in-memory structures should set this bit. * A volume that must always read from disk or always perform a network * transaction should not set this bit. * * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports * file sizes larger than 4GB, and potentially up to 2TB; it does not * indicate whether the filesystem supports files larger than that. * * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny * modes (e.g. "open for read write, deny write"; effectively, mandatory * file locking based on open modes). * * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN * file flag, and the UF_HIDDEN flag is mapped to that volume's native * "hidden" or "invisible" bit (which may be the invisible bit from the * Finder Info extended attribute). * * VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability * to derive a pathname to the root of the file system given only the * id of an object. This also implies that object ids on this file * system are persistent and not recycled. This is a very specialized * capability and it is assumed that most file systems will not support * it. Its use is for legacy non-posix APIs like ResolveFileIDRef. * * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support * returning values for total data blocks, available blocks, or free blocks * (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically, * those values were set to 0xFFFFFFFF for volumes that did not support them. * * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent * decompression of compressed files using decmpfs. * * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the * only legitimate attributes for obtaining object IDs from this volume and the * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID, * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined. * * VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory * hard links. * * VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs * (an ID which persists across object ID changes) for document revisions. * * VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write * generation counts (a count of how many times an object has been modified) * * VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support * setting the UF_IMMUTABLE flag. * * VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting * permissions. * * VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with * other filesystems i.e. multiple logical filesystems can exist in the same * "partition". An implication of this is that the filesystem which sets * this capability treats waitfor arguments to VFS_SYNC as bit flags. * * VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group * that implies multiple volumes must be mounted in order to boot and root the * operating system. Typically, this means a read-only system volume and a * writable data volume. */ #define VOL_CAP_FMT_PERSISTENTOBJECTIDS 0x00000001 #define VOL_CAP_FMT_SYMBOLICLINKS 0x00000002 #define VOL_CAP_FMT_HARDLINKS 0x00000004 #define VOL_CAP_FMT_JOURNAL 0x00000008 #define VOL_CAP_FMT_JOURNAL_ACTIVE 0x00000010 #define VOL_CAP_FMT_NO_ROOT_TIMES 0x00000020 #define VOL_CAP_FMT_SPARSE_FILES 0x00000040 #define VOL_CAP_FMT_ZERO_RUNS 0x00000080 #define VOL_CAP_FMT_CASE_SENSITIVE 0x00000100 #define VOL_CAP_FMT_CASE_PRESERVING 0x00000200 #define VOL_CAP_FMT_FAST_STATFS 0x00000400 #define VOL_CAP_FMT_2TB_FILESIZE 0x00000800 #define VOL_CAP_FMT_OPENDENYMODES 0x00001000 #define VOL_CAP_FMT_HIDDEN_FILES 0x00002000 #define VOL_CAP_FMT_PATH_FROM_ID 0x00004000 #define VOL_CAP_FMT_NO_VOLUME_SIZES 0x00008000 #define VOL_CAP_FMT_DECMPFS_COMPRESSION 0x00010000 #define VOL_CAP_FMT_64BIT_OBJECT_IDS 0x00020000 #define VOL_CAP_FMT_DIR_HARDLINKS 0x00040000 #define VOL_CAP_FMT_DOCUMENT_ID 0x00080000 #define VOL_CAP_FMT_WRITE_GENERATION_COUNT 0x00100000 #define VOL_CAP_FMT_NO_IMMUTABLE_FILES 0x00200000 #define VOL_CAP_FMT_NO_PERMISSIONS 0x00400000 #define VOL_CAP_FMT_SHARED_SPACE 0x00800000 #define VOL_CAP_FMT_VOL_GROUPS 0x01000000 /* * VOL_CAP_INT_SEARCHFS: When set, the volume implements the * searchfs() system call (the vnop_searchfs vnode operation). * * VOL_CAP_INT_ATTRLIST: When set, the volume implements the * getattrlist() and setattrlist() system calls (vnop_getattrlist * and vnop_setattrlist vnode operations) for the volume, files, * and directories.
