Volumes that support VolFS and can support Carbon File ID 153 * references should set this bit. 154 * 155 * VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic 156 * links. The symlink(), readlink(), and lstat() calls all use this 157 * symbolic link. 158 * 159 * VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links. 160 * The link() call creates hard links. 161 * 162 * VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting 163 * a journal used to speed recovery in case of unplanned shutdown 164 * (such as a power outage or crash). This bit does not necessarily 165 * mean the volume is actively using a journal for recovery. 166 * 167 * VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using 168 * a journal for use in speeding recovery after an unplanned shutdown. 169 * This bit can be set only if VOL_CAP_FMT_JOURNAL is also set. 170 * 171 * VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not 172 * store reliable times for the root directory, so you should not 173 * depend on them to detect changes, etc. 174 * 175 * VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files. 176 * That is, files which can have "holes" that have never been written 177 * to, and are not allocated on disk. Sparse files may have an 178 * allocated size that is less than the file's logical length. 179 * 180 * VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs) 181 * that have never been written to must appear to contain zeroes. When 182 * this bit is set, the volume keeps track of allocated but unwritten 183 * runs of a file so that it can substitute zeroes without actually 184 * writing zeroes to the media. This provides performance similar to 185 * sparse files, but not the space savings. 186 * 187 * VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are 188 * case sensitive (upper and lower case are different). When clear, 189 * an upper case character is equivalent to a lower case character, 190 * and you can't have two names that differ solely in the case of 191 * the characters. 192 * 193 * VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names 194 * preserve the difference between upper and lower case. If clear, 195 * the volume may change the case of some characters (typically 196 * making them all upper or all lower case). A volume that sets 197 * VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING. 198 * 199 * VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers 200 * (especially Carbon) that statfs() is fast enough that its results 201 * need not be cached by those upper layers. A volume that caches 202 * the statfs information in its in-memory structures should set this bit. 203 * A volume that must always read from disk or always perform a network 204 * transaction should not set this bit. 205 * 206 * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports 207 * file sizes larger than 4GB, and potentially up to 2TB; it does not 208 * indicate whether the filesystem supports files larger than that. 209 * 210 * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny 211 * modes (e.g. "open for read write, deny write"; effectively, mandatory 212 * file locking based on open modes). 213 * 214 * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN 215 * file flag, and the UF_HIDDEN flag is mapped to that volume's native 216 * "hidden" or "invisible" bit (which may be the invisible bit from the 217 * Finder Info extended attribute). 218 * 219 * VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability 220 * to derive a pathname to the root of the file system given only the 221 * id of an object. This also implies that object ids on this file 222 * system are persistent and not recycled. This is a very specialized 223 * capability and it is assumed that most file systems will not support 224 * it. Its use is for legacy non-posix APIs like ResolveFileIDRef. 225 * 226 * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support 227 * returning values for total data blocks, available blocks, or free blocks 228 * (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically, 229 * those values were set to 0xFFFFFFFF for volumes that did not support them. 230 * 231 * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent 232 * decompression of compressed files using decmpfs. 233 * 234 * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that 235 * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the 236 * only legitimate attributes for obtaining object IDs from this volume and the 237 * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID, 238 * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined. 239 * 240 * VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory 241 * hard links. 242 * 243 * VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs 244 * (an ID which persists across object ID changes) for document revisions. 245 * 246 * VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write 247 * generation counts (a count of how many times an object has been modified) 248 * 249 * VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support 250 * setting the UF_IMMUTABLE flag. 251 * 252 * VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting 253 * permissions. 254 * 255 * VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with 256 * other filesystems i.e. multiple logical filesystems can exist in the same 257 * "partition". An implication of this is that the filesystem which sets 258 * this capability treats waitfor arguments to VFS_SYNC as bit flags. 259 * 260 * VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group 261 * that implies multiple volumes must be mounted in order to boot and root the 262 * operating system. Typically, this means a read-only system volume and a 263 * writable data volume. 264 * 265 * VOL_CAP_FMT_SEALED: When set, this volume is cryptographically sealed. 266 * Any modifications to volume data or metadata will be detected and may 267 * render the volume unusable. 268 */ 269 #define VOL_CAP_FMT_PERSISTENTOBJECTIDS 0x00000001 270 #define VOL_CAP_FMT_SYMBOLICLINKS 0x00000002 271 #define VOL_CAP_FMT_HARDLINKS 0x00000004 272 #define VOL_CAP_FMT_JOURNAL 0x00000008 273 #define VOL_CAP_FMT_JOURNAL_ACTIVE 0x00000010 274 #define VOL_CAP_FMT_NO_ROOT_TIMES 0x00000020 275 #define VOL_CAP_FMT_SPARSE_FILES 0x00000040 276 #define VOL_CAP_FMT_ZERO_RUNS 0x00000080 277 #define VOL_CAP_FMT_CASE_SENSITIVE 0x00000100 278 #define VOL_CAP_FMT_CASE_PRESERVING 0x00000200 279 #define VOL_CAP_FMT_FAST_STATFS 0x00000400 280 #define VOL_CAP_FMT_2TB_FILESIZE 0x00000800 281 #define VOL_CAP_FMT_OPENDENYMODES 0x00001000 282 #define VOL_CAP_FMT_HIDDEN_FILES 0x00002000 283 #define VOL_CAP_FMT_PATH_FROM_ID 0x00004000 284 #define VOL_CAP_FMT_NO_VOLUME_SIZES 0x00008000 285 #define VOL_CAP_FMT_DECMPFS_COMPRESSION 0x00010000 286 #define VOL_CAP_FMT_64BIT_OBJECT_IDS 0x00020000 287 #define VOL_CAP_FMT_DIR_HARDLINKS 0x00040000 288 #define VOL_CAP_FMT_DOCUMENT_ID 0x00080000 289 #define VOL_CAP_FMT_WRITE_GENERATION_COUNT 0x00100000 290 #define VOL_CAP_FMT_NO_IMMUTABLE_FILES 0x00200000 291 #define VOL_CAP_FMT_NO_PERMISSIONS 0x00400000 292 #define VOL_CAP_FMT_SHARED_SPACE 0x00800000 293 #define VOL_CAP_FMT_VOL_GROUPS 0x01000000 294 #define VOL_CAP_FMT_SEALED 0x02000000 295 296 /* 297 * VOL_CAP_INT_SEARCHFS: When set, the volume implements the 298 * searchfs() system call (the vnop_searchfs vnode operation). 299 * 300 * VOL_CAP_INT_ATTRLIST: When set, the volume implements the 301 * getattrlist() and setattrlist() system calls (vnop_getattrlist 302 * and vnop_setattrlist vnode operations) for the volume, files, 303 * and directories.
