2000-12-13 Theodore Ts'o * closefs.c (ext2fs_update_fs_dynamic_rev): New function suggested by Andreas Dilger to update the filesystem revision to EXT2_DYNAMIC_REV. * swapfs.c (ext2fs_swap_super): Add byte swapping for the journal fields. 2000-12-09 * ext2fs.h, mkjournal.c (ext2fs_add_journal_fs, ext2fs_add_journal_device): Add a new argument to the APIs of these function, which is a flags word. This is used to allow the creation of a V1 superblock for those folks who are using ext3 0.3b in production. Note, the user-land interface for getting at this flag won't be documented, as the V1 superblock is deprecated. * mkjournal.c (init_journal_superblock): Sync Stephen's changes which creates a V2 superblock instead of a V1 superblock. 2000-11-21 * test_io.c (test_write_blk, test_write_byte): Fix typos pointed out by Andreas Dilger. 2000-11-05 * imager.c (ext2fs_image_{inode,super,bitmap}_{read,write}, ext2_fs.h, Makefile.in: New file that has routines that save ext2fs metadata to a file. * ext2_err.et.in (EXT2_ET_MAGIC_E2IMAGE): New error code assigned. * e2image.h: New file which defines the file format for the ext2 image file. (Saved copy of ext2 metadata to a file as a saving throw against worst-case damage.) 2000-11-01 * inode.c (ext2fs_flush_icache): Add new function ext2fs_flush_icache() which flushes the internal inode cache. Applications which modify the inode table blocks directly must call this function. 2000-10-26 * mkjournal.c: Add #include of netinet/in.h, since Solaris requires it for ntohl(). * ext2_io.h (io_channel_write_byte): Add new interface to allow callers to write specific byte ranges. This is an optional interface, which not all IO channels may implement. * unix_io.c (unix_write_byte): * test_io.c (test_write_byte): Add implementation of the write_byte function. * closefs.c (write_primary_superblock, ext2fs_flush): Add a new function which writes the primary superblock. If the IO channel supports writing raw bytes directly, only fields which were modified are written to the disk. This makes it safe(r) to use utilities like tune2fs on a mounted filesystem. * freefs.c (ext2fs_free): Free the original superblock if it is available. * openfs.c (ext2fs_open): Store a copy of the original superblock when opening it. * ext2fs.h: Add a field to store the original superblock in the ext2 context structure. 2000-10-24 * llseek.c: Add #ifdef's for IA64 (it's a 64-bit platform, so we don't need to use llseek). 2000-10-24 * Makefile.in, ext2fs.h, jfs_dat.h, mkjournal.c: Add functions for creating an ext3 journal on a filesystem. 2000-08-21 * ext2_err.et.in (EXT2_JOURNAL_NOT_BLOCK): Add new error code. 2000-08-22 * unix_io.c: Make massive changes to support a multiple block writethrough cacheing. * ext2_io.h: Added flags field to the io_channel structure. 2000-08-19 * finddev.c, ext2fs.h, Makefile.in: Add new file, finddev.c, which provides the function ext2fs_find_block_device(). This function returns the pathname to a block device, given its device number. 2000-07-13 * Release of E2fsprogs 1.19 2000-07-07 Theodore Ts'o * ext2fs.h (EXT2_LIB_FEATURE_INCOMPAT_SUPP): Add EXT3_FEATURE_INCOMPAT_RECOVER (aka needs_recovery) to the list of filesystem flags supported by the library. 2000-07-04 Theodore Ts'o * ext2fs.h: Update to include latest journalling additions to the superblock. * dll/jump.funcs: Add new jumptable entries for ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and ext2fs_badblocks_equal. * tst_badblocks.c: Update test program to test ext2fs_read_bb_FILE2 and ext2fs_write_FILE. * write_bb_file.c (ext2fs_write_bb_FILE): New function which writes out bad blocks list to a file. * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which changes the callback function to take two additional arguments; a private blind pointer supplied by the caller, and pointer to a char * containing a pointer to the invalid string. * badblocks.c (ext2fs_badblocks_equal): Add new function which returns true if two badblocks list are equal. * Makefile.in: Remove explicit link of -lc in the shared library. (It shouldn't be necessary, and is harmful in some cases). 2000-06-10 Theodore Ts'o * getsize.c (main): Add debugging code under #ifdef DEBUG 2000-05-27 Theodore Ts'o * mkdir.c (ext2fs_mkdir): Read the parent directory's inode earlier, so that if there's an error reading it, we can more cleanly back out of the operation. 2000-05-25 * getsize.c (ext2fs_get_device_size): Use open64() instead of open() if it exists. Under linux, manually define the ioctl for BLKGETSIZE if it isn't already defined and it's safe to do so. * unix_io.c (unix_open): Use open64() instead of open() if it exists. * llseek.c: Simplify header includes of unistd.h. If lseek64 is available (and prototypes are defined) use it in preference to llseek. * Makefile: Add hack dependency rule so that parallel makes work correctly. 2000-05-18 Theodore Ts'o * ext2fs.h: Add appropriate ifdef's to support C++ compilation. 2000-04-03 Theodore Ts'o * block.c: Readibility tweak in conditionals involving ctx->fs->flags. * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine how to define __s64 and __u64. Turn off "compression is experimental" warning if the cpp macro I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined. 2000-02-11 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR. Conditionally include Compression as a supported type if ENABLE_COMPRESSION (via --enable-compression) is turned on. * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap. 2000-02-08 * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap, ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap, ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap): Change to return the previous state of the bit that is being marked or unmarked. For speed optimization. 2000-02-02 Theodore Ts'o * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not needed any more; we know it will always be i_generation. Add support for swapping the high bits of the uid and gid. 1999-11-19 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link counts if the link was successful. Patch suggested by jeremy@goop.org. * Makefile.in (distclean): Remove TAGS and Makefile.in.old from the source directory. 1999-11-10 * Release of E2fsprogs 1.18 1999-11-08 * Makefile.in (tst_badblocks): Add freefs.o to the object list, since ext2fs_badblocks_list_free was moved to freefs.c. * tst_badblocks.c: Use the newer badblocks API names. Add duplicate blocks to the test inputs to test dealing with adding blocks which are already in the badblocks list. * badblocks.c (ext2fs_badblocks_list_add): If appending to the end of the list, use a shortcut O(1) operations instead of an O(n) operation. (Idea suggested by David Beattie.) * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead of badblocks_list_free(), to save a procedure call. 1999-10-26 * Release of E2fsprogs 1.17 1999-10-26 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't seem to handle ~0UL the same way as they used to. 1999-10-25 * nt_io.c (_OpenNtName): Open the device using FILE_SYNCHRONOUS_IO_NONALERT instead of FILE_SYNCHRONOUS_IO_ALERT (nt_open): At the end of the device open routine, unlock the drive but do not dismount it. * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to detect the Hurd OS. 1999-10-22 * Release of E2fsprogs 1.16 1999-10-22 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link(). * link.c (ext2fs_link): This call now uses the low three bits of the flags parameter to pass the directory filetype information; it will set the directory entry FILETYPE information if the filesystem supports it. * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock option is set, then create the '.' and '..' entries with the filetype set to EXT2_FT_DIR. 1999-09-24 * nt_io.c: New file which supports I/O under Windows NT. 1999-09-07 * ext2fs.h: Add new fields for journalling and define new feature bits used by newer filesystems: IMAGIC_INODES, HAS_JOURNAL, RECOVER. * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where we update the inode block count and size files so that the block count field is updated correctly when we create an indirect block. 1999-07-18 Theodore Ts'o * Release of E2fsprogs 1.15 1999-06-23 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3 kernels that use i_generation instead of i_version. Patch supplied by Jon Bright . 1999-06-21 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted directory entry before calling the callback function. This should prevent some core dumps of insufficiently paranoid callback functions. 1999-05-29 * ext2fs.h: Add feature definition for AFS IMAGIC inodes. * fileio.c (ext2fs_file_open): Remove obsolete comment stating that we don't handle writing yet (we do). Fixed bug where we weren't allocating a big enough buffer for ext2_bmap. 1999-05-03 * openfs.c (ext2fs_open): Check to make sure that the number of blocks per group is not zero --- if so, it must be a bad superblock! 1999-01-09 Theodore Ts'o * Release of E2fsprogs 1.14 1999-01-07 Theodore Ts'o * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if the inode number is zero; if it's zero, return EXT2_ET_BAD_INODE_NUM. 1998-12-30 Theodore Ts'o * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead of EXT2_FIRST_INO to ensure compatibility with Linux 1.2 header files. Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the non-Linux case to use EINVAL by default, unless it isn't defined, in which case we use EXT2_ET_INVALID_ARGUMENT instead. 1998-12-15 Theodore Ts'o * Release of E2fsprogs 1.13 1998-12-03 Theodore Ts'o * Makefile.in: Updated dependencies. 1998-09-22 Theodore Ts'o * initialize.c (ext2fs_initialize): Make sure that we allocate enough inodes so that we can make a valid filesystem. 1998-09-02 Theodore Ts'o * rw_bitmaps.c: Fixed signed/unsigned warnings. * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the function declaration. * dblist.c (make_dblist): Add safety check in case the dblist pointer passed in is null (in which case, assign it to fs->dblist). Fixed some signed/unsigned warnings. * bmap.c: Make addr_per_block be of type blk_t to avoid signed/unsigned warnings. * namei.c (ext2fs_follow_link): Remove uneeded extern from the function declaration. * get_pathname.c (get_pathname_proc): Use return value from ext2fs_get_mem, instead of checking if &gp->name is NULL. * dir_iterate.c (ext2fs_process_dir_block): * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern from the function declaration. * block.c (ext2fs_block_iterate2): If the read_inode call fails, return the error directly instead of jumping to the cleanup routine, since we don't need to do any cleanup. * alloc_table.c (ext2fs_allocate_group_table): Make this function take a dgrp_t for its group argument. * ext2fs.h: Make dgrp_t an __u32 type, and make fs->desc_group_count be of type dgrp_t. 1998-07-27 Theodore Ts'o * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment than 10 blocks when we need to expand the size of the badblocks list. 1998-07-09 Theodore Ts'o * Release of E2fsprogs 1.12 1998-06-30 Theodore Ts'o * closefs.c (ext2fs_flush): Update the s_block_group_nr field as appropriate for all of the block group copies, so that it's clear where the beginning of the filesystem is on the disk. (For when the partition table gets scrod.) * ext2fs.h: Change the name of the feature from EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel). 1998-06-18 Theodore Ts'o * inode.c (get_next_blockgroup): Fix bug where if get_next_blockgroup() is called early because of a missing inode table in a block group, the current_inode counter wasn't incremented correctly. 1998-06-16 Theodore Ts'o * read_bb.c (ext2fs_read_bb_inode): Make function more robust against a completely trashed bad block inode. 1998-06-10 Theodore Ts'o * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if the stride length hits a bad value, we retry the block allocation starting at the beginning of the block group. * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c, expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be e2_blkcnt_t to avoid collision with LFS API. 1998-05-01 Theodore Ts'o * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a way that avoids overflows on disk sizes greater than 4GB. 1998-04-28 Theodore Ts'o * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the return type for comparison functions for qsort. * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function declaration. 1998-04-26 Theodore Ts'o * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do inline functions. * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to evade a potential problem with glibc's header files trying to spike out linux/types.h. * ext2fs.h (ext2fs_resize_mem): Change the function prototype to include the old size of the memory, which is needed for some braindamaged memory allocation systems that don't support realloc(). * badblocks.c (ext2fs_badblocks_list_add): bb_inode.c (clear_bad_block_proc): dblist.c (ext2fs_add_dir_block): icount.c (insert_icount_el): irel_ma.c (ima_put): rs_bitmap.c (ext2fs_resize_generic_bitmap): Update functions to pass the old size of the memory to be resized to ext2fs_resize_mem(). 1998-03-30 Theodore Ts'o * Makefile.in: Change to use new installation directory variables convention. Fix uninstall rules to take $(DESTDIR) into account. 1998-03-29 Theodore Ts'o * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform with 32 bit longs, then we need to manually define __s64 and __u64, since the current kernel header files don't define these if __STRICT_ANSI__ is defined. This is a problem if we are compiling with full GCC warnings, since we do need 64 bit support. * Makefile.in (OBJS): Remove bmove.o from files to be built, since we're not using ext2fs_move_blocks() and there is some question as to its usefulness in its current form. * bmap.c (block_bmap): Remove unused function. * bmove.c (process_block): Fix -Wall warning. 1998-03-23 Theodore Ts'o * block.c (ext2fs_block_iterate3): Make the ref_offset field contain the offset into the inode.i_blocks array when ref_block is zero. Since we haven't done a formal release of e2fsprogs since block_iterate2 was first introduced, I removed block_iterate2, and renamed block_iterate3 to be block_iterate2. * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c, expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change use of block_iterate and block_iterate2 to block_iterate2 with the new prototype for the interator function. (using blkcnt_t forr blockcount) 1998-03-21 Theodore Ts'o * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap, s_prealloc_blocks, s_prealloc_dir_blocks). Added conditional defines of new features COMPAT_DIR_PREALLOC, RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR, INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed the library to declare that we support COMPAT_DIR_PREALLOC, INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE. * fileio.c: Rename function ext2fs_file_llseek to be ext2fs_file_lseek, which is more accurate. * block.c: Add new function ext2fs_block_iterate3 which calls the iterator function with the blockcount argument of type blkcnt_t. This version of the function is allowed to handle large files; the other fucntions are not. * ext2fs.h: Add new type blkcnt_t * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG * block.c (ext2fs_block_iterate2): Fix bug where the block count field wasn't getting correctly incremented for sparse files when the indirect or doubly-indirect block specified in the inode was zero. Sun Mar 8 22:42:47 1998 Theodore Ts'o * unlink.c (unlink_proc): * lookup.c (lookup_proc): * link.c (link_proc): * get_pathname.c (get_pathname_proc): * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits from dirent->name_len, so it can be used for other purposes. * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE, and indicate that we have support for this incompatible option. Mon Feb 23 08:46:33 1998 Theodore Ts'o * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED. Fri Feb 20 23:58:01 1998 Theodore Ts'o * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the number of directories when the block group information is unreliable. 1998-02-20 Theodore Y. Ts'o * inode.c (ext2fs_get_next_inode): Always do the check to see if the inode table is missing so that we catch the case where the first block group is missing. * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's needed. Mon Feb 16 16:16:00 1998 Theodore Ts'o * ext2_io.h, ext2fs.h: Protect against being included multiple times. * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h" * test_io.c (test_flush): Add a debugging printf when the flush method is called. * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already read in, return right away. Sun Feb 1 08:20:24 1998 Theodore Ts'o * bitops.h: Don't try to do i386 inline asm functions if the compiler isn't GCC. * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h, instead of linux/types.h, and e2_bitops.h instead of ext2fs/bitops.h. * icount.c, version.c: Don't #include , as it isn't necessary. Sat Jan 17 13:13:31 1998 Theodore Ts'o * inode.c (ext2fs_open_inode_scan): Initialize the group variables so that we don't need to call get_next_blockgroup() the first time around. Saves a bit of time, and prevents us from needing to assign -1 to current_group (which is an unsigned value). * icount.c (insert_icount_el): Cast the estimated number of inodes from a float to an ino_t. * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c, bitmaps.c, bitops.c, block.c, bmap.c, bmove.c, brel_ma.c, check_desc.c, closefs.c, cmp_bitmaps.c, dblist.c, dblist_dir.c, dir_iterate.c, dirblock.c, dupfs.c, expanddir.c, ext2fs.h, fileio.c, freefs.c, get_pathname.c, getsize.c, icount.c, initialize.c, inline.c, inode.c, irel_ma.c, ismounted.c, link.c, lookup.c, mkdir.c, namei.c, native.c, newdir.c, openfs.c, read_bb.c, read_bb_file.c, rs_bitmap.c, rw_bitmaps.c, swapfs.c, test_io.c, tst_badblocks.c, tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c, valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is defined, then assume all of the ext2-specific header files are in a flat directory. * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast all assignments from void * to be compatible with C++. Tue Jan 6 11:28:15 1998 Theodore Ts'o * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to make sure the contents of the disk are flushed to disk. Mon Dec 29 14:39:13 1997 Theodore Ts'o * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to avoid C++ namespace clash. * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to avoid C++ namespace clash. * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c, irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c, ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c, unlink.c: Change private to be priv_data (to avoid C++ namespace clash) Fri Nov 28 09:26:31 1997 Theodore Ts'o * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more paranoid about validating the directory counts from the block group information. * all files: Don't include stdlib.h anymore; include it in ext2_fs.h, since that file requires stdlib.h Thu Nov 20 16:07:38 1997 Theodore Ts'o * expanddir.c (ext2fs_expand_dir): Check to make sure the block bitmap is loaded, and return an error if it is not. (expand_dir_proc): Only use ext2fs_write_dir_block when writing a directory block, not when writing out a fresh indirect block. Tue Nov 11 22:46:45 1997 Theodore Ts'o * Makefile.in, tst_getsize.c: Added new file which is used to test the ext2fs_get_device_size function. * ext2_err.et.in (EXT2_ET_UNIMPLEMENTED): Added new error code. Sun Nov 2 20:36:13 1997 Theodore Ts'o * ext2fs.h: Make ext2fs_get_mem take an unsigned argument. * fileio.c (ext2fs_file_get_size, ext2fs_file_set_size, ext2fs_file_get_fs): New functions added. Fri Oct 31 12:16:52 1997 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call com_err if OMIT_COM_ERR is defined. Thu Oct 30 11:33:57 1997 Theodore Ts'o * Rename new error codes to _ET_ in them for consistency. Sat Oct 25 00:06:58 1997 Theodore Ts'o * [all files, basically]: Added definition of ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and changed all library routines to use these wrapper functions. * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND instead of the system error messages. * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND * ext2fs.h: Added function declarations and constants for bmap.c and fileio.c. * ext2_err.et.in: Added new error messages EXT2_FILE_RO and EXT2_ET_MAGIC_EXT2_FILE * Makefile.in: Added files bmap.c and fileio.c, and temporarily commented out brel_ma.c and irel_ma.c * bmap.c: New file which maps a file's logical block number to its physical block number. * fileio.c: New file which implements simple file reading and writing primitives. * alloc.c (ext2fs_alloc_block): New function which allocates a block, zeros it, and updates the filesystem accounting records appropriately. Wed Oct 22 16:47:27 1997 Theodore Ts'o * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY, EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL, EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY * Change various library files to use these functions instead of EINVAL, ENOENT, etc. Mon Oct 20 19:32:40 1997 Theodore Ts'o * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we need to declare llseek(). Sun Oct 19 18:56:22 1997 Theodore Ts'o * Rename io.h to be ext2_io.h (avoid namespace collisions) * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H Fri Oct 3 13:35:59 1997 Theodore Ts'o * llseek.c (ext2fs_llseek): Fix type error for ext2fs_llseek() * icount.c (ext2fs_icount_validate): * bmove.c (process_block): Fix lint error in type for fprintf(). Mon Sep 15 11:45:09 1997 Theodore Ts'o * inode.c (ext2fs_check_directory): Add support for the callback to return the error code EXT2_ET_CALLBACK_NOTHANDLED. Thu Sep 4 12:28:22 1997 Theodore Ts'o * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the padding of the bitmap to be all one's. Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o * llseek.c: Added missing semicolon to glibc fixup declaration of llseek(). * bmove.c: Add #include of errno.h Sat Aug 23 22:47:46 1997 Theodore Ts'o * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've added a new field to the io_channel (app_data). * io.h: Add a new element to the io_channel structure, app_data. * initialize.c, openfs.c: Set io->app_data to point at the filesystem handle. Thu Aug 14 08:14:17 1997 Theodore Ts'o * io.h: Change the prototype of ext2fs_llseek() to use int's instead of unsigned int's. * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype to make life easer for GNU Libc 2. * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2 filesystem has its bitmaps stored as 32-bit words with bit 0 as the LSB of each word. Thus a bitmap with only bit 0 set would be, as a string of bytes, 00 00 00 01 00 ... To cope with this, we byte-reverse each word of a bitmap if we have a big-endian filesystem, that is, if we are *not* byte-swapping other word-sized numbers.

Sun Jun 8 16:24:39 1997 Theodore Ts'o * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap wasn't being returned to the caller. * alloc_tables.c (ext2fs_allocate_group_table): Add new function ext2fs_allocate_group_table() which sets the group tables for a particular block group. The relevant code was factored out of ext2fs_allocate_tables(). * dblist.c (make_dblist): Adjust the initial size of the directory block list to be a bit more realistic (ten plus twice the number of directories in the filesystem). Thu May 8 22:19:09 1997 Theodore Ts'o * badblocks.c (ext2fs_badblocks_list_test): Fix bug where ext2fs_badblocks_list_test would test the list (and exceed array boundaries) if there were no bad blocks on the bad blocks list. (Showed up when user tried: mke2fs -c -b 4096). Thu Apr 24 12:16:42 1997 Theodre Ts'o * Release of E2fsprogs version 1.10 Thu Apr 24 10:13:42 1997 Theodre Ts'o * alloc_tables.c (ext2fs_allocate_tables): Correctly place the inode and block bitmaps based on the RAID 0 stride parameter (which is passed by mke2fs). * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by mke2fs to communicate the stride length to ext2fs_allocate_tables() Wed Apr 23 21:50:42 1997 Theodre Ts'o * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2 systems. (We can't assume that the new filesystem types are supported.) Wed Apr 23 18:40:53 1997 Theodore Ts'o * alloc_tables.c (ext2fs_allocate_tables): Make sure that we allocate the inode and block bitmaps inside block group at all times. Mon Apr 21 00:06:28 1997 Theodore Ts'o * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the filesystem has no free blocks, ext2fs_new_block would loop forever. * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only free if refcount goes to zero. * inode.c (create_icache): Initialize refcount to 1. * ext2fsP.h: Added refcount to ext2_inode_cache * dblist.c (ext2fs_copy_dblist): New function to copy a directory block list. * badblocks.c (ext2fs_badblocks_copy): New function to copy a badblocks structure.

(unix_close, test_close): Decrement the refcount and only close the io_channel if the refcount goes to 0. * io.h: Add refcount to the io_channel structure. Add new macro interface io_channel_bumpcount() to bump the refcount. Thu Apr 17 20:25:03 1997 Theodore Ts'o * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode cache in the filesystem handle, instead of the inode cache in a static variable. * freefs.c: Added static function to free the inode cache (called by ext2fs_free). * ext2fsP.h: Added definition of the ext2_inode_cache structures. * ext2fs.h: Added pointer to the inode_cache structure. * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind): If there are holes in the indirect, doubly indirect, or triply indirect blocks, increment the block count field automatically.

Sat Apr 5 12:42:42 1997 Theodore Ts'o * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and inode bitmaps at staggered locations across the block groups, to avoid concentrating the bitmaps on a small number of disks when using striped RAID arrays. * initialize.c (ext2fs_initialize): By default, choose the maximum possible number of blocks per group (based on the size of the bitmaps in the blocksize). Fri Apr 4 11:28:16 1997 Theodore Ts'o * initialize.c (ext2fs_initialize): Add support for EXT2_COMPAT_SPARSE_SUPER feature. * closefs.c (ext2fs_bg_has_super): New function to determine whether or a particular block group should have a superblock and block group descriptor.

Wed Mar 26 00:43:52 1997 Theodore Ts'o * icount.c (ext2fs_create_icount): Change function so that it also takes a new argument which contains a "hint" icount structure. This "hint" icount allows the create function to set up the sorted list in advance. This reduces significantly the amount of data moving needed to insert these inodes into the list later. * icount.c (ext2fs_icount_validate): New function which validates that the icount structure's rep invariant. * icount.c (get_icount_el): Completely revamped implementation to subsume put_icount_el(). Put_icount_el() used to use an O(N) implementation to insert in the middle of the icount list. It now uses a O(ln N) to search for where the icount should be inserted, and then uses a memcpy to move the list down (instead of a for loop). * icount.c (ext2fs_icount_fetch, ext2fs_icount_store, ext2fs_icount_increment, ext2fs_icount_decrement): Check to see if the inode is within bounds; if it isn't, return EINVAL. * bitops.h (ext2fs_test_generic_bitmap): Fix error message given when a bad inode number is passed to test_generic_bitmap to be EXT2FS_TEST_ERROR instead of the wrong EXT2FS_UNMARK_ERROR.

Thu Feb 6 10:00:13 1997 Theodore Ts'o * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use use ext2fs_badblocks_* instead of badblocks_* * bb_compat.c: New file which translates between old badblocks_*() names to ext2fs_badblocks_*() * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from link.c (since e2fsck doesn't use ext2fs_unlink()). * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains bitmap resizing routine moved from bitmaps.c, since e2fsck doesn't need to use this function. * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file, since e2fsck only needs ext2fs_lookup. Mon Feb 3 10:11:40 1997 Theodore Ts'o * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not already set; this is needed so that programs like dump which use the inode scan functions will deal with filesystems that have bad blocks in the inode table. Sun Feb 2 00:17:36 1997 Theodore Ts'o * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate): Moved to ext2fsP.h, since it doesn't need to be part of the public interface. * dir_iterate.c: Move ext2_dir_iterate out of namei.c. Sat Feb 1 10:14:55 1997 Theodore Ts'o * dblist.c (ext2fs_get_num_dirs): New file, which implements a directory block list abstraction. (Code moved from e2fsck). * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to to inode.c (since no one else should be peeking inside it!) * valid_blk.c (ext2_inode_has_valid_blocks): New function. * openfs.c (ext2fs_open): Check the feature set in the ext2 superblock, and refuse to open filesystems if they contain incompatible features. (Can be overriden with the EXT2_FLAG_FORCE Sun Jan 12 11:31:46 1997 Theodore Ts'o * block.c (ext2fs_block_iterate2): Added new function ext2fs_block_iterate2 which changes the function signature of the callback function to include the referencing block and offset. * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function ext2fs_inode_scan_goto_blockgroup which allows an application to jump to a particular block group while doing an inode scan. Wed Jan 1 23:50:12 1997 Theodore Ts'o * dirblock.c: Include string.h, since we use memcpy(). Tue Dec 3 12:27:29 1996 Theodore Ts'o * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns a long not an int; this doesn't matter on i386 machines, but it does on Alpha's. Fri Nov 29 20:57:37 1996 Theodore Ts'o * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode table pointer is NULL, then return an error indicating that the inode table is missing. (get_next_blockgroup, get_next_blocks, ext2fs_get_next_inode): Don't treat a missing inode table as permanent error. Return MISSING_INODE_TABLE, but as an advisory error code, much like BAD_BLOCK_IN_INODE_TABLE. * rw_bitmaps.c (ext2fs_write_block_bitmap, ext2fs_write_inode_bitmap): If the inode or block bitmap block is zero, then don't write out the inode or block bitmap. The idea here is to avoid stomping on the superblock. (read_bitmaps): If the inode or block bitmap block is zero, then fill in that portion of the inode or block bitmap with all zeros. * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad blocks in inode table when the inode table size is non-standard (and can therefore span blocks). Tue Oct 29 20:13:14 1996 Theodore Ts'o * alloc.c (ext2fs_new_block): Fix fencepost error in ext2fs_new_block; make sure we don't try to allocate the first block beyond the end of the filesystem. Mon Oct 14 11:00:48 1996 Theodore Ts'o * inode.c (check_for_inode_bad_blocks): New function called by get_next_blocks() to avoid reading in bad blocks marked in fs->badblocks. Inodes located in bad blocks are returned by ext2fs_get_next_inode() returns the error code EXT2_ET_BAD_BLOCK_IN_INODE_TABLE. * alloc_tables.c (ext2fs_allocate_tables): New function which performs the part of mke2fs's job of allocating the filesystem tables. * test_io.c (test_close): IO manager which is used for testing purposes. Sun Oct 13 04:31:57 1996 Theodore Ts'o * inode.c (ext2fs_get_next_inode): Separate out the function of setting up for a new block group to get_next_blockgroup(). Separate out the function of reading in blocks of the inode table to get_next_blocks(). * ext2fs.h: Add the badblocks list to the ext2_filsys entry * badblocks.c (badblocks_list_add, badblocks_list_test): Add blocks to the badblock list in sorted order. This allows badblocks_list_test to be coded using a binary search for speed. Tue Oct 8 02:02:03 1996 Theodore Ts'o * Release of E2fsprogs version 1.06 Mon Oct 7 00:44:17 1996 Theodore Ts'o * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c, open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for consistency's sake. * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is set, then only write out the master superblock. Sun Oct 6 21:45:26 1996 Theodore Ts'o * block.c (ext2fs_block_iterate): Fixed bug which caused block_iterate to fail to handle HURD created filesystems; it tested the inode translator field before the inode was loaded. Tue Sep 17 14:08:24 1996 Theodore Ts'o * initialize.c (ext2fs_initialize): Make sure the description for the inode bitmap is set correctly. * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

(ext2fs_namei): Extended to have support for chasing symbolic links. ext2fs_namei() still returns an inode which is a symbolic link. Symbolic links are only chased while resolving the containing directory. To chase symbolic links of the final result, use ext2fs_follow_link(). Mon Aug 26 23:46:07 1996 Theodore Ts'o * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP. * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru). Thu Aug 22 00:40:18 1996 Theodore Ts'o * initialize.c (ext2fs_initialize): On systems where the byte order is not i386 compatible, set the swap_byte flag. * inode.c (inocpy_with_swap): Check to see if inode contains a fast symlink before swapping the inode block fields. This required adding a new argument to inocpy_with_swap to determine whether the mode field is in host order or not. Wed Aug 21 00:45:42 1996 Theodore Ts'o * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On the sparc, if EXT2_STD_BITOPS set, use the standard i386-compatible bitmask operations, instead on the non-standard native bitmask operators. Fri Aug 9 11:11:35 1996 Theodore Ts'o * block.c (ext2fs_block_iterate): Cause block iterator to return the HURD translator block (along with everything else). If the flag BLOCK_FLAG_DATA_ONLY is passed to the block iterator, then don't return any meta data blocks (including the HURD translator). Wed Jul 17 17:13:34 1996 Theodore Ts'o * gen_uuid.c: New file, which generates DCE-compatible UUIDs. * uuid.c: New file, containing UUID utility functions. Tue Jul 16 10:19:16 1996 Theodore Ts'o * ext2fs.h: Add a definition of the "real" ext2 superblock. Fri May 24 14:54:55 1996 Theodore Ts'o * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type. Sun May 19 15:39:03 1996 Theodore Ts'o * openfs.c (ext2fs_open): If the blocksize in the superblock is zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since that's a basic value that must be correct for the rest of the library to work. * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error code. Thu May 16 11:12:30 1996 Theodore Ts'o * Release of E2fsprogs version 1.04 Wed Mar 27 00:33:40 1996 * Release of E2fsprogs version 1.03 Tue Mar 26 12:06:32 1996 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): Change the m68k bit numbering for bitmasks to match with the bit numbering used by all other ext2 implementations.

Ts'o * getsize.c (ext2fs_get_device_size): New function that determins the size of a device. Used by mke2fs and e2fsck. Sat Aug 12 03:09:54 1995 Remy Card * Makefile.in (install): Install static libraries in $(ulibdir) (/usr/lib on Linux) instead of $(libdir) (/lib on Linux). Wed Aug 9 17:04:23 1995 Theodore Y. Ts'o * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap): Move these functions to freefs.c. * closefs.c (ext2fs_flush): If swapping blocks, clear the group descriptors shadow memory to keep purify quiet. (This also has the nice benefit that the unused portion of the shadow descriptors are zeroed out.) * dirblock.c (ext2fs_write_dir_block): We need to use dirent->rec_len *before* it's byteswapped to find the location of the next directory structure! * alloc.c (ext2fs_new_inode): Fix bug which could potentially cause ext2fs_new_inode to loop infinitely if we're trying to allocate an inode in group #0 and there are no free inodes at all in the system. * closefs.c: #include if it exists. Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for BLOCK_FLAG_APPEND. Added documentation for the block interator flags.

Zaitcev so that the C language versions of these functions are more portable. They will now work on both little and big endian systems, and the assumption that 32-bit integers are used is gone. * bitops.h (ext2_swab16, ext2_swab32): Added new functions for doing byte swapping. * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that byte swapping should take place.

Sat Jul 15 04:23:37 1995 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer; if the magic number is correct, it will be allocated. Fri Jul 14 19:02:59 1995 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind): Don't recompute block_nr each loop; just increment it! Factor check of BLOCK_FLAG_APPEND out of the loop. Factor mask of BLOCK_CHANGED into changed variable out of the loop. (block_iterate_ind, in particular, gets called a lot, so every little optimization helps.) Thu Jul 13 08:02:45 1995 * block.c (block_iterate_ind, block_iterate_dind, block_iterate_tind): Precompute limit of loop to speed up block_iterate_ind and company. * bitops.h (ext2fs_fast_mark_block_bitmap, ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap, ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap, ext2fs_fast_test_inode_bitmap): Add fast version of these functions, which don't do range checking. * bitops.h (ext2fs_get_block_bitmap_start, ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end, ext2fs_get_inode_bitmap_end): Add new accessor functions which return the start and end points of the bitmaps. Tue Jul 11 18:59:41 1995 * llseek.c (ext2_llseek): If the offset is small enough, use lseek instead of llseek. The errno if the offset is too large and lseek is not supported should be EINVAL, not -EINVAL. Thu Jun 15 23:43:02 1995 Remy Card * Makefile.in: Added support for ELF shared libraries. Fixed typos in the compilation rules. (distclean): Added Makefile. * llseek.c (llseek): New function, if llseek() does not exist in the C library. (ext2_llseek): Changed to call llseek(). Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long. Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR. * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of the S_*, which are normally defined in . This allows us to compile e2fsprogs on a non-Linux system, which may have a different value for S_IFDIR. Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti(); this is a user-mode application! Thu Jun 8 13:13:22 1995 Miles Bader * llseek.c: Put the include of inside the #ifdef __linux__ so that non-linux systems won't see it. * alloc.c: Include if possible. * badblocks.c: Ditto. * bb_inode.c: Ditto. * bitmaps.c: Ditto. * block.c: Ditto. * expanddir.c: Ditto. * get_pathname.c: Ditto. * initialize.c: Ditto. * inode.c: Ditto. * llseek.c: Ditto. * mkdir.c: Ditto. * namei.c: Ditto. * newdir.c: Ditto. * openfs.c: Ditto. * rw_bitmaps.c: Ditto. * unix_io.c: Ditto. * Makefile.in: Rewritten to conform to GNU coding standards and support separate compilation directories. Thu May 11 04:13:12 1995 * initialize.c (ext2fs_initialize): Don't allow more than one bitmaps's worth of inodes in a group. Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o * llseek.c (ext2_llseek): Added error checking to the llseek() compat code to protect against overflow. This only applies to 1.0 and early 1.1 kernels, which don't support the llseek() system call. Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11) * unix_io.c (unix_open): Initialize the read_error and write_error io_channel pointers to be null. * bb_inode.c (clear_bad_block_proc): If an illegal block number is found, clear it but don't try to update the filesystem accounting information, since that's hopeless anyway. * block.c (bloblock_iterate_ind, bloblock_iterate_dind, bloblock_iterate_tind): Check to see if the indirect blocks are valid before trying to read them. * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK, EXT2_ET_BAD_TIND_BLOCK): Add new error codes. * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap, ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an illegal block or inode number is passed in, return instead of trying to test, set, or clear the bit. Mon Nov 7 21:32:33 1994 Remy Card * Makefile: Added a dummy install target in case shared libraries are not built. Mon Oct 24 14:11:44 1994 (tytso@rsx-11) * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how the real last block of the bitmap should be calculated. Wed Sep 7 10:05:36 1994 (tytso@rsx-11) * bitmaps.c (ext2fs_fudge_inode_bitmap_end, ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap, ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap): Add magic number checking for the inode and block bitmaps. * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct magic number for a block bitmap instead of an inode bitmap. * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add magic number checking for the inode_scan structure. * badblocks.c (badblocks_list_free, badblocks_list_add, badblocks_list_test, badblocks_list_iterate_begin, badblocks_list_iterate, badblocks_list_iterate_end): Add magic number checking for the badblocks_list and badblocks_iterate structures. * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL): * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk, unix_write_blk, unix_flush): Add magic number checking both for io_channel structure and unix_private_data structure. * openfs.c (ext2fs_open): Add check for io_manager structure's magic number. * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap, ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap, ext2fs_read_bitmaps, ext2fs_write_bitmaps): * read_bb.c (ext2fs_read_bb_inode): * read_bb_file.c (ext2fs_read_bb_FILE): * newdir.c (ext2fs_new_dir_block): * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei): * link.c (ext2fs_link, ext2fs_unlink): * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode, ext2fs_write_inode, ext2fs_get_blocks, ext2fs_check_directory): * get_pathname.c (ext2fs_get_pathname): * expanddir.c (ext2fs_expand_dir): * block.c (ext2fs_block_iterate): * bitmaps.c (ext2fs_allocate_inode_bitmap, ext2fs_allocate_block_bitmap): * bb_inode.c (ext2fs_update_bb_inode): * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks): * check_desc.c (ext2fs_check_desc): * closefs.c (ext2fs_close, ext2fs_flush): * freefs.c (ext2fs_free): Add check for ext2_filsys magic number. * Makefile: * ext2fs.h: * openfs.c: * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from openfs.c into its own file. * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for structure magic numbers. * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear the EXT2_VALID_FS flag in the backup superblock blocks, so that if someone uses the -b option to specify the use of the backup superblock --- this usually means that the main superblock is toast. :-) * ext2fs.h: * ext2_err.et (EXT2_ET_REV_TOO_HIGH): * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a revision level to the superblock. Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11) * ext2fs.h: * bitmaps.c: * bitops.c * bitops.h: * openfs.c: * initialize.c: Completely revamped the inode and block bitmap structures, so that they can be better chance of being extensible in a shared library. They are now their own type, instead of being a char *. Also, the function signatures of ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap, ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were changed to eliminate the ext2_filsys argument, since it is no longer necessary. Wed Aug 17 21:46:44 1994 Remy Card (card@bbj) * unix_io.c (unix_read_blk and unix_write_blk): use the llseek system call if available. * llseek.c: new file. This is the stub calling the llseek system call which allows supports for 2GB+ file systems. * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores the creator operating system. Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11) * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up the group descriptor statistics in addition to everything else. This relieves mke2fs of the responsibility of doing it. * bitops.c, bitops.h: Add assembly inline functions for the 68000. Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or not the generic C function equivalents should be included or not. * openfs.c (ext2fs_open): If a superblock is specified, then use the backup group descriptors that go along with this superblock, instead of using the primary group descriptors. This allows e2fsck to recover filesystems where the primary group descriptors have been trashed.
