Volumes that support VolFS and can support Carbon File ID 137 * references should set this bit. 138 * 139 * VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic 140 * links. The symlink(), readlink(), and lstat() calls all use this 141 * symbolic link. 142 * 143 * VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links. 144 * The link() call creates hard links. 145 * 146 * VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting 147 * a journal used to speed recovery in case of unplanned shutdown 148 * (such as a power outage or crash). This bit does not necessarily 149 * mean the volume is actively using a journal for recovery. 150 * 151 * VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using 152 * a journal for use in speeding recovery after an unplanned shutdown. 153 * This bit can be set only if VOL_CAP_FMT_JOURNAL is also set. 154 * 155 * VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not 156 * store reliable times for the root directory, so you should not 157 * depend on them to detect changes, etc. 158 * 159 * VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files. 160 * That is, files which can have "holes" that have never been written 161 * to, and are not allocated on disk. Sparse files may have an 162 * allocated size that is less than the file's logical length. 163 * 164 * VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs) 165 * that have never been written to must appear to contain zeroes. When 166 * this bit is set, the volume keeps track of allocated but unwritten 167 * runs of a file so that it can substitute zeroes without actually 168 * writing zeroes to the media. This provides performance similar to 169 * sparse files, but not the space savings. 170 * 171 * VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are 172 * case sensitive (upper and lower case are different). When clear, 173 * an upper case character is equivalent to a lower case character, 174 * and you can't have two names that differ solely in the case of 175 * the characters. 176 * 177 * VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names 178 * preserve the difference between upper and lower case. If clear, 179 * the volume may change the case of some characters (typically 180 * making them all upper or all lower case). A volume that sets 181 * VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING. 182 * 183 * VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers 184 * (especially Carbon) that statfs() is fast enough that its results 185 * need not be cached by those upper layers. A volume that caches 186 * the statfs information in its in-memory structures should set this bit. 187 * A volume that must always read from disk or always perform a network 188 * transaction should not set this bit. 189 * 190 * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports 191 * file sizes larger than 4GB, and potentially up to 2TB; it does not 192 * indicate whether the filesystem supports files larger than that. 193 * 194 * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny 195 * modes (e.g. "open for read write, deny write"; effectively, mandatory 196 * file locking based on open modes). 197 * 198 * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN 199 * file flag, and the UF_HIDDEN flag is mapped to that volume's native 200 * "hidden" or "invisible" bit (which may be the invisible bit from the 201 * Finder Info extended attribute). 202 * 203 * VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability 204 * to derive a pathname to the root of the file system given only the 205 * id of an object. This also implies that object ids on this file 206 * system are persistent and not recycled. This is a very specialized 207 * capability and it is assumed that most file systems will not support 208 * it. Its use is for legacy non-posix APIs like ResolveFileIDRef. 209 * 210 * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support 211 * returning values for total data blocks, available blocks, or free blocks 212 * (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically, 213 * those values were set to 0xFFFFFFFF for volumes that did not support them. 214 * 215 * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent 216 * decompression of compressed files using decmpfs. 217 * 218 * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that 219 * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the 220 * only legitimate attributes for obtaining object IDs from this volume and the 221 * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID, 222 * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined. 223 */ 224#define VOL_CAP_FMT_PERSISTENTOBJECTIDS 0x00000001 225#define VOL_CAP_FMT_SYMBOLICLINKS 0x00000002 226#define VOL_CAP_FMT_HARDLINKS 0x00000004 227#define VOL_CAP_FMT_JOURNAL 0x00000008 228#define VOL_CAP_FMT_JOURNAL_ACTIVE 0x00000010 229#define VOL_CAP_FMT_NO_ROOT_TIMES 0x00000020 230#define VOL_CAP_FMT_SPARSE_FILES 0x00000040 231#define VOL_CAP_FMT_ZERO_RUNS 0x00000080 232#define VOL_CAP_FMT_CASE_SENSITIVE 0x00000100 233#define VOL_CAP_FMT_CASE_PRESERVING 0x00000200 234#define VOL_CAP_FMT_FAST_STATFS 0x00000400 235#define VOL_CAP_FMT_2TB_FILESIZE 0x00000800 236#define VOL_CAP_FMT_OPENDENYMODES 0x00001000 237#define VOL_CAP_FMT_HIDDEN_FILES 0x00002000 238#define VOL_CAP_FMT_PATH_FROM_ID 0x00004000 239#define VOL_CAP_FMT_NO_VOLUME_SIZES 0x00008000 240#define VOL_CAP_FMT_DECMPFS_COMPRESSION 0x00010000 241#define VOL_CAP_FMT_64BIT_OBJECT_IDS 0x00020000 242 243 244/* 245 * VOL_CAP_INT_SEARCHFS: When set, the volume implements the 246 * searchfs() system call (the vnop_searchfs vnode operation). 247 * 248 * VOL_CAP_INT_ATTRLIST: When set, the volume implements the 249 * getattrlist() and setattrlist() system calls (vnop_getattrlist 250 * and vnop_setattrlist vnode operations) for the volume, files, 251 * and directories.
