| |
| * 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. |

| |
| * 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(). |

| |
| * 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 <tytso@localhost.mit.edu> |
| |

| inode and block bitmaps based on the RAID 0 stride |
| parameter (which is passed by mke2fs). |
| |

| version string (instead of the hard-coded one). |
| |
| * alloc_tables.c (ext2fs_allocate_tables): If the last block is |

| |
| Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |

| EXT2_COMPAT_SPARSE_SUPER feature. |
| |
| * closefs.c (ext2fs_bg_has_super): New function to determine |

| or not the superblock should be written out for the block |
| group. |

| |
| Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> |
| |
| * 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. |

| when a bad inode number is passed to test_generic_bitmap |
| to be EXT2FS_TEST_ERROR instead of the wrong |
| EXT2FS_UNMARK_ERROR. |
| |
| Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu> |
| |
| * Release of E2fsprogs version 1.07 |
| |
| Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> |

| Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> |
| |
| * alloc.c (ext2fs_get_free_blocks): Change routine to use |

| ext2fs_test_block_bitmap_range: New inline functions which |
| test to see whether a contiguous range of blocks is |
| available. |

| 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * dirblock.c: Include string.h, since we use memcpy(). |
| |
| Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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. |
| |

| |
| * 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 <tytso@rsts-11.mit.edu> |
| |

| * 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 <tytso@rsts-11.mit.edu> |
| |
| * 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 <tytso@rsts-11.mit.edu> |
| |

| superblock. |
| |
| * namei.c (ext2fs_follow_link): New function. |
| (ext2fs_namei): Extended to have support for chasing |

| 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 <tytso@rsts-11.mit.edu> |
| |
| * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP. |

| 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 |

| |
| * openfs.c (ext2fs_open): If the blocksize in the superblock is |

| Move these functions to freefs.c. |
| |
| * closefs.c (ext2fs_flush): If swapping blocks, clear the group |

| to desp ext2 filesystem structures. |
| |

| supplied by Pete A. 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 |

| |
| * block.c (block_iterate_ind, block_iterate_dind, |

| particular, gets called a lot, so every little |
| optimization helps.) |

| |
| * 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 <sys/stat.h>. 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 <tytso@lurch.mit.edu> |
| |
| * 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 <miles@churchy.gnu.ai.mit.edu> |
| |
| * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef |

| Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu> |
| |
| * 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 <tytso@localhost> |
| |
| * 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. |

| 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 |

| |
| Mon Nov 7 21:32:33 1994 Remy Card <card@bbj> |
| |
| * Makefile: Added a dummy install target in case shared libraries |

| * 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 |

| |
| * unix_io.c (unix_read_blk and unix_write_blk): use the llseek |

| 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. |
| |
| |
