Whitespace cleanup. - -2002-05-21 Theodore Ts'o <tytso@mit.edu> - - * ext2_ext_attr.h: Update to V2 version of the Bestbits format. - -2002-05-16 Andreas Dilger <adilger@clusterfs.com> - - * ext2_fs.h: Change limits to support filesystems with 8k blocks. - - * initialize.c (ext2fs_initialize): Remove assumption that - blocksizes are always <= 4k. - -2002-05-11 Theodore Ts'o <tytso@mit.edu> - - * bmap.c (ext2fs_bmap): Fix bug which caused ext2fs_bmap to fail - silently if inode pointer is NULL (and ext2fs_bmap is - expected to read the inode itself). - -2002-04-27 Theodore Ts'o <tytso@mit.edu> - - * ismounted.c (check_mntent_file, is_swap_device): Verify that the - file we are checking is a block device file before looking - at st_rdev, since it's not valid for normal files. - (is_swap_device): Move so that it is outside the - HAVE_MNTENT_H, so that it is always built. - -2002-03-11 Theodore Tso <tytso@mit.edu> - - * dirblock.c (ext2fs_read_dir_block2, ext2fs_write_dir_block): New - functions which take an extra flags argument. The flag - EXT2_DIRBLOCK_V2_STRUCT will reverse when the name_len - field is byte swampped on big-endian machines, since in - the V2 structure, name_len is a char field which is - doesn't need to be byte swapped --- except if an - old-style kernel had byte-swapped the name_len field - as part of the V1 structure. - - * ext2_err.et.in (EXT2_ET_DIRHASH_UNSUPP): New error code - - * dirhash.c (ext2fs_dirhash): New function which calculates the - hash for a filename in an indexed directory. - -2002-03-08 Theodore Tso <tytso@mit.edu> - - * Release of E2fsprogs 1.27 - -2002-03-07 Theodore Tso <tytso@mit.edu> - - * ext2fs.h (ext2fs_inode_io_intern): Add missing function prototype. - - * bmap.c, fileio.c, inode_io.c, tst_badblocks.c, - tst_byteswap.c: Fix gcc -Wall complaints - - * Makefile.in (check): Use LD_LIBRARY_PATH to run test programs. - (From Philipp Thomas <pthomas@suse.de>) - -2002-02-25 Theodore Tso <tytso@mit.edu> - - * ext2_fs.h: Add structure definitions for the directory indexing - extension. - -2002-02-23 Theodore Tso <tytso@mit.edu> - - * unix_io.c (unix_open): Fix 2.4 resource limit workaround so that - it doesn't break things on mis32, sparc32, and alpha - platforms. - -2002-02-21 Theodore Tso <tytso@mit.edu> - - * ismounted.c (is_swap_device): Fix file descriptor/memory leak; - we were missing an fclose(). - -2002-02-20 Theodore Tso <tytso@mit.edu> - - * Makefile.in, inode_io.c, ext2fs.h, ext2_err.et.in: Add new io - abstraction interface which exports an ext2 inode. - - * ext2fs.h, fileio.c (ext2fs_file_flush): Export ext2fs_file_flush - as a public interface. Change void * to const void * in - ext2fs_file_write's interface. - - * test_io.c (test_close), unix_io.c (unix_close): Remove unneeded - conditional; save a few bytes. - -2002-02-12 Theodore Tso <tytso@mit.edu> - - * Makefile.in (tst_badblocks): Add some extra .o files when - linking the debugging program tst_badblocks which are - needed if we aren't compiling with inline functions enable. - - * kernel-list.h (__inline__): On non-gcc and non-Watcom compilers, - define away __inline__ since it may not be supported. - - * kernel-jbd.h (jbd_debug): For systems that don't do STDC, use a - stripped down jbd_debug that doesn't use variadic - arguments. This will cause warnings under AIX, but things - should still build. - -2002-02-03 Theodore Tso <tytso@thunk.org> - - * Release of E2fsprogs 1.26 - -2002-02-03 Theodore Tso <tytso@mit.edu> - - * mkdir.c (ext2fs_mkdir): Change to use ext2fs_inode_alloc_stats2 - so that the number of directories in use is adjusted - appropriately. - - * alloc_stats.c (ext2fs_inode_alloc_stats2): Add new function - which optionally will modify the number of directories - count. - -2002-01-03 Theodore Tso <tytso@mit.edu> - - * dir_iterate.c (ext2fs_dir_iterate2, ext2fs_process_dir_block): - Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED, - which will return deleted directory entries. - ext2fs_dir_iterate2 takes a new callback function which - is identical with the one used by - ext2fs_dblist_dir_iterate(). If the directory entry is - deleted, the callback function will be called with the - entry paraemter set to DIRENT_DELETED_FILE. - - * Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats, - ext2fs_block_alloc_stats): New functions which update - block/inode allocation statistics in the bitmaps, block - group descriptors, and superblock. - - * mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir), - expanddir.c (expand_dir_proc), bb_inode.c - (clear_bad_block_proc, set_bad_block_proc, - ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block): - Update to use new block/inode allocation statistics. - -2001-12-24 Theodore Tso <tytso@mit.edu> - - * ismounted.c (is_swap_device): New function used by - ext2fs_check_if_mounted and ext2fs_check_mount_point which - determines whether or not the specified device is a swap - device by using /proc/swaps. More bulletproofing for - idiotic/careless system administrators! - - * ext2fs.h, openfs.c (ext2fs_open), initialize.c - (ext2fs_initialize), mkdir.c (ext2fs_mkdir): Add a new - field to struct_ext2_filsys, umask. This field is - initialize to 022, and affects ext2fs_mkdir in the obvious - way. (In the future umask should also affect new file - creation routines, but the fileio functions don't - currently support this yes.) - - * ismounted.c (check_mntent_file): Stat all of the entries in - /etc/mtab and/or /proc/mounts in order to catch dim-witted - system administrators who might have created alias - devices. - -2001-12-23 Theodore Tso <tytso@mit.edu> - - * Makefile.in, jfs_user.h: Move linux/jbd.h to - ext2fs/kernel-jbd.h, to avoid using the system header - file version of hbd.h when using diet glibc (since it - forcibly adds /usr/include to the beginning of the - include search path.) - - * kernel-jbd.h, kernel-list.h, jfs_compat.h: Move files from - include/linux directory. - -2001-12-16 Theodore Tso <tytso@mit.edu> - - * bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap), - ext_attr.c (ext2fs_read_ext_attr, ext2fs_write_ext_attr), - fileio.c (ext2fs_file_write): Fix gcc -Wall nits - - * Makefile.in, jfs_user.h: linux/jfs.h has been renamed to - linux/jbd.h - -2001-12-03 Theodore Tso <tytso@mit.edu> - - * unix_io.c (unix_open): Make sure the ulimit workaround works - regardless of the version of glibc which is used to - compild e2fsprogs. - -2001-11-26 Theodore Tso <tytso@mit.edu> - - * unix_io.c (unix_open): Work around a bug in 2.4.10+ kernels by - trying to unset the filesize limit if at all possible, - if a block device is getting opened. (The filesize limit - shouldn't be applied against writes to a block device, but - starting in 2.4.10, the kernel is doing this.) - -2001-11-05 Theodore Tso <tytso@mit.edu> - - * mkjournal.c (ext2fs_add_journal_inode): When creating a .journal - file on adding a journal to an already-mounted filesystem, - try to clear the ext2 file attributes on an already - existing .journal file so that we don't fail if on a - partially added journal to the filesystem. - - * ext2_fs.h: Define a new ext2 file attribute, EXT2_NOTAIL_FL, - which signals that a particular inode should not have the - last bits of data (the "tail") be merged with another - file. This is necessary to keep LILO happy. - -2001-09-20 Theodore Tso <tytso@thunk.org> - - * Release of E2fsprogs 1.25 - -2001-09-16 Theodore Tso <tytso@mit.edu> - - * ext2_ext_attr.h: Remove unneeded #include of <linux/config.h> - which was breaking the build on the Hurd. (Addresses - Debian bug #112414). - -2001-09-13 Theodore Ts'o <tytso@mit.edu> - - * ismounted.c (check_mntent_file): We now validate the entry in - /etc/mtab to make sure the filesystem is really mounted, - since some broken distributions (read: Slackware) have - buggy boot scripts that don't initialize /etc/mtab before - checking non-root filesystems. (Slackware also doesn't - check the root filesystem separately, and reboot if the - root filesystem had changes applied to it, which is - dangerous and broken.) - -2001-09-02 Theodore Tso <tytso@thunk.org> - - * Release of E2fsprogs 1.24a - -2001-08-30 Theodore Tso <tytso@thunk.org> - - * Release of E2fsprogs 1.24 - -2001-08-30 Theodore Tso <tytso@valinux.com> - - * getsize.c (ext2fs_get_device_size): Back out BLKGETSIZE64 - changes, since the ioctl number has been reused by another - unofficial patch. - -2001-08-15 Theodore Tso <tytso@valinux.com> - - * Release of E2fsprogs 1.23 - -2001-08-05 Theodore Tso <tytso@valinux.com> - - * alloc.c (ext2fs_new_inode, ext2fs_new_block): Use the fast - version of the bitmap test routines to speed up these - routines. (At some point I may want to make these - routines use the find_first_bit functions, but that will - add a lot of complexity since it means that these - functions will have to break the bitmap abstraction - boundary. It's not clear it's worth it.) - - * mkjournal.c (mkjournal_proc): Remember the last block allocated - to speed up ext2fs_new_block(). - -2001-07-29 Theodore Tso <tytso@valinux.com> - - * finddev.c (scan_dir): Fix memory leak; we weren't calling - closedir() when exiting the function in all cases. - -2001-07-27 Theodore Tso <tytso@valinux.com> - - * mkjournal.c (ext2fs_create_journal_superblock): Set the first - block usable in the journal for external journals to be 2 - or 3, depending on the blocksize, so that the existing - kernel code does the right thing. - - * getsize.c (ext2fs_get_device_size): Add support for the - BLKGETSIZE64 ioctl. (Ioctl defined by unofficial patches - from Ben LaHaise, but it's likely this interface won't - change.) - - * mkjournal.c (ext2fs_add_journal_device): Use the correct block - when writing the journal superblock, too. (Oops! Needed - to make 1k filesystems with external journal to work.) - -2001-07-26 Theodore Tso <tytso@valinux.com> - - * mkjournal.c (ext2fs_add_journal_device): Use the correct block - to find the journal superblock if the blocksize is 1024. - -2001-07-21 Theodore Tso <tytso@valinux.com> - - * ext2_err.et.in (EXT2_ET_LOAD_EXT_JOURNAL): Add new error code - -2001-07-20 Theodore Tso <tytso@valinux.com> - - * ext_attr.c (ext2fs_write_ext_attr): When writing the extended - attribute block, set the filesystem changed bit. - - * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set): - Comment out these functions since we're not using them. - -2001-07-10 Theodore Tso <tytso@valinux.com> - - * closefs.c (write_primary_superblock): After writing changes to - the primary superblock, update the original superblock - copy so we don't have to re-write those changes in the - future. - (ext2fs_flush): Clear the superblock dirty flag after - we've flushed out changes to disk. - -2001-07-07 Theodore Tso <tytso@valinux.com> - - * bitops.h (ext2fs_find_first_bit_set): Use %esi instead of %ebx - to avoid register conflicts when compiling in PIC mode. - -2001-07-04 Theodore Tso <tytso@valinux.com> - - * bitops.h (ext2fs_find_first_bit_set, ext2fs_find_next_bit_set): - Add new functions (C and in i386 assembler) which quickly - find bits set in a bitmask. - -2001-06-23 Theodore Tso <tytso@valinux.com> - - * Makefile.in, ext_attr.c, ext2_attr.c, ext2fs.h: Add new files - ext2_ext_attr.h and ext_attr.c for extended attributes - support. - - * Release of E2fsprogs 1.22 - -2001-06-22 Theodore Tso <tytso@valinux.com> - - * mkjournal.c (ext2fs_add_journal_inode): Move close of file - descriptor so that adding a journal to a mounted - filesystem doesn't die. (Fixes a bug accidentally - introduced in e2fsprogs 1.21.) - - * mkjournal.c (ext2fs_add_journal_inode): Only use fchflags if - HAVE_CHFLAGS and UF_NODUMP are defined, since the Hurd has - fchflags without defining UF_NODUMP. (Addresses Debian - bug #101361) - - * flushb.c: Use platform independent method of defining the - BLKFLSBUF and FDFLUSH ioctl's. Also include sys/mount.h - since on newer glibc's BLKFLSBUF is defined there. - - * bitops.h: The C language versions of ext2fs_swab16/32 need to be - included if EXT2FS_ENABLE_SWAPFS is defined, since we need - to support byte swapping even if we don't support the - conversion functions. (Fixes Debian bug #101686). - - * dirblock.c (ext2fs_read_dir_block): Remove use of dir_entry_2 - since the byte-swapping code all assumes the - ext2_dir_entry structure. (It's a question of whether or - not name_len should be byte-swapped or not, and whether - it's a 16 bit or 8 bit field.) - -2001-06-15 Theodore Tso <tytso@valinux.com> - - * Release of E2fsprogs 1.21 - -2001-06-15 Theodore Tso <tytso@valinux.com> - - * Makefile.in: Fix bug in installation of ext2_types.h. It is a - file which is generated and is therefore found in the - build directory, not source directory. - - * ismounted.c (check_mntent_file): Use a test file in / to check - to see if the root filesystem is mounted read-only. This - protects against the case where /etc might not be on /, as - well as the case where /etc/mtab doesn't exist.

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 <card@bbj> - - * 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. - - |
