| Version 0.92 (2002-03-29) | |
| ========== | |
| * Minor cleanup. Ran Lindent on the sources. | |
| Version 0.92 (2002-03-27) | |
| ========== | |
| * Fixed module makefile problem. It was not compiling all the correct | |
| source files! | |
| * Removed duplicated function definition | |
| * Fixed potential null pointer dereference when reporting an error | |
| Version 0.91 (2002-03-26) | |
| ========== | |
| * Oy! Fixed stupid bug that would cause an unresolved symbol error. | |
| Thanks to Laszlo Boszormenyi for pointing this out to me. | |
| Version 0.9 (2002-03-14) | |
| ========== | |
| * Added Sergey S. Kostyliov's patch to eliminate memcpy() overhead | |
| from b+tree operations. Changes the befs_read_datastream() interface. | |
| * Segregated the functions that interface directly with the linux vfs | |
| interface into their own file called linuxvfs.c. [WD] | |
| Version 0.64 (2002-02-07) | |
| ========== | |
| * Did the string comparison really right this time (btree.c) [WD] | |
| * Fixed up some places where I assumed that a long int could hold | |
| a pointer value. (btree.c) [WD] | |
| * Andrew Farnham <andrewfarnham@uq.net.au> pointed out that the module | |
| wouldn't work on older (<2.4.10) kernels due to an unresolved symbol. | |
| This is bad, since 2.4.9 is still the current RedHat kernel. I added | |
| a workaround for this problem (compatibility.h) [WD] | |
| * Sergey S. Kostyliov made befs_find_key() use a binary search to find | |
| keys within btree nodes, rather than the linear search we were using | |
| before. (btree.c) [Sergey S. Kostyliov <rathamahata@php4.ru>] | |
| * Made a debian package of the source for use with kernel-package. [WD] | |
| Version 0.63 (2002-01-31) | |
| ========== | |
| * Fixed bug in befs_find_brun_indirect() that would result in the wrong | |
| block being read. It was introduced when adding byteswapping in | |
| 0.61. (datastream.c) [WD] | |
| * Fixed a longstanding bug in befs_find_key() that would result in it | |
| finding the first key that is a substring of the string it is searching | |
| for. For example, this would cause files in the same directory with | |
| names like file1 and file2 to mysteriously be duplicates of each other | |
| (because they have the same inode number). Many thanks to Pavel Roskin | |
| for reporting this serious bug!!! | |
| (btree.c) [WD] | |
| * Added support for long symlinks, after Axel Dorfler explained up how | |
| they work. I had forgotten all about them. (inode.c, symlink.c) [WD] | |
| * Documentation improvements in source. [WD] | |
| * Makefile fix for independent module when CONFIG_MODVERSION is set in | |
| kernel config [Pavel Roskin <proski@gnu.org>] | |
| * Compile warning fix for namei.c. [Sergey S. Kostyliov <rathamahata@php4.ru>] | |
| Version 0.62 | |
| ========== | |
| * Fixed makefile for module install [WD] | |
| Version 0.61 (2002-01-20) | |
| ========== | |
| * Made functions in endian.h to do the correct byteswapping, no matter | |
| the arch. [WD] | |
| * Abbandoned silly checks for a NULL superblock pointer in debug.c. [WD] | |
| * Misc code cleanups. Also cleanup of this changelog file. [WD] | |
| * Added byteswapping to all metadata reads from disk. | |
| Uses the functions from endian.h [WD] | |
| * Remove the typedef of struct super_block to vfs_sb, as it offended | |
| certain peoples' aesthetic sense. [WD] | |
| * Ditto with the befs_read_block() interface. [WD] | |
| Version 0.6 (2001-12-15) | |
| ========== | |
| * Cleanup of NLS functions (util.c) [WD] | |
| * Make directory lookup/read use the NLS if an iocharset is provided. [WD] | |
| * Fixed stupid bug where specifying the uid or gid mount options as '0' | |
| would result in the filesystem using the on-disk uid and gid. [WD] | |
| * Added mount option to control debug printing. | |
| The option is, simply enough, 'debug'. | |
| (super.c, debug.c) [WD] | |
| * Removed notion of btree handle from btree.c. It was unnecessary, as the | |
| linux VFS doesn't allow us to keep any state between calls. Updated | |
| dir.c, namei.c befs_fs.h to account for it. [WD] | |
| * Improved handleing of overflow nodes when listing directories. | |
| Now works for overflow nodes hanging off of nodes other than the root | |
| node. This is the cleaner solution to Brent Miszalaski's problem. [WD] | |
| * Added new debug/warning/error print functions in debug.c. | |
| More flexible. Will soon be controllable at mount time | |
| (see TODO). [WD] | |
| * Rewrote datastream position lookups. | |
| (datastream.c) [WD] | |
| * Moved the TODO list to its own file. | |
| Version 0.50 (2001-11-13) | |
| ========== | |
| * Added workaround for mis-understanding of the nature of the b+trees used | |
| in directories. A cleaner solution will come after I've thought about it | |
| for a while. Thanks to Brent Miszalaski for finding and reporting this bug. | |
| (btree.c) [WD] | |
| * Minor cleanups | |
| * Added test for "impossible" condition of empty internal nodes in | |
| seekleaf() in btree.c [WD] | |
| * Implemented the abstracted read_block() in io.c [WD] | |
| * Cleaned up the inode validation in inode.c [WD] | |
| * Anton Altaparmakov figured out (by asking Linus :) ) what was causing the | |
| hanging disk io problem. It turns out you need to have the sync_pages | |
| callback defined in your address_space_ops, even if it just uses the | |
| default linux-supplied implementation. Fixed. Works now. | |
| (file.c) [WD] | |
| * Anton Altaparmakov and Christoph Hellwig alerted me to the fact that | |
| filesystem code should be using GFP_NOFS instead of GFP_KERNEL as the | |
| priority parameter to kmalloc(). Fixed. | |
| (datastream.c, btree.c super.c inode.c) [WD] | |
| * Anton also told me that the blocksize is not allowed to be larger than | |
| the page size in linux, which is 4k i386. Oops. Added a test for | |
| (blocksize > PAGE_SIZE), and refuse to mount in that case. What this | |
| practically means is that 8k blocksize volumes won't work without a major | |
| restructuring of the driver (or an alpha or other 64bit hardware). [WD] | |
| * Cleaned up the befs_count_blocks() function. Much smarter now. | |
| And somewhat smaller too. [WD] | |
| * Made inode allocations use a slab cache | |
| (super.c inode.c) [WD] | |
| * Moved the freeing of the private inode section from put_inode() to | |
| clear_inode(). This fixes a potential free twice type bug. Put_inode() | |
| can be called multiple times for each inode struct. [WD] | |
| * Converted all non vfs-callback functions to use befs_sb_info as the | |
| superblock type, rather than struct super_block. This is for | |
| portablity. [WD] | |
| * Fixed a couple of compile warnings due to use of malloc.h, when slab.h | |
| is the new way. (inode.c, super.c) [WD] | |
| * Fixed erronous includes of linux/befs_fs_i.h and linux/befs_fs_sb.h | |
| in inode.c [WD] | |
| Version 0.45 (2001-10-29) | |
| ========== | |
| * Added functions to get the private superblock and inode structures from | |
| their enclosing public structures. Switched all references to the | |
| private portions to use them. (many files) [WD] | |
| * Made read_super and read_inode allocate the private portions of those | |
| structures into the generic pointer fields of the public structures | |
| with kmalloc(). put_super and put_inode free them. This allows us not | |
| to have to touch the definitions of the public structures in | |
| include/linux/fs.h. Also, befs_inode_info is huge (because of the | |
| symlink string). (super.c, inode.c, befs_fs.h) [WD] | |
| * Fixed a thinko that was corrupting file reads after the first block_run | |
| is done being read. (datastream.c) [WD] | |
| * Removed fsync() hooks, since a read-only filesystem doesn't need them. | |
| [Christoph Hellwig]. | |
| * Fixed befs_readlink() (symlink.c) [Christoph Hellwig]. | |
| * Removed all the Read-Write stuff. I'll redo it when it is time to add | |
| write support (various files) [WD]. | |
| * Removed prototypes for functions who's definitions have been removed | |
| (befs_fs.h) [WD]. | |
| Version 0.4 (2001-10-28) | |
| ========== | |
| * Made it an option to use the old non-pagecache befs_file_read() for | |
| testing purposes. (fs/Config.in) | |
| * Fixed unused variable warnings when compiling without debugging. | |
| * Fixed a bug where the inode and super_block didn't get their blockbits | |
| fields set (inode.c and super.c). | |
| * Release patch version 11. AKA befs-driver version 0.4. | |
| * Thats right. New versioning scheme. | |
| I've done some serious testing on it now (on my box anyhow), and it | |
| seems stable and not outragously slow. Existing features are more-or-less | |
| correct (see TODO list). But it isn't 1.0 yet. I think 0.4 gives me some | |
| headroom before the big 1.0. | |
| 2001-10-26 | |
| ========== | |
| * Fixed date format in this file. Was I smoking crack? | |
| * Removed old datastream code from file.c, since it is nolonger used. | |
| * Generic_read_file() is now used to read regular file data. | |
| It doesn't chew up the buffer cache (it does page io instead), and seems | |
| to be about as fast (even though it has to look up each file block | |
| indivdualy). And it knows about doing readahead, which is a major plus. | |
| So it does i/o in much larger chunks. It is the correct linux way. It | |
| uses befs_get_block() by way of befs_readpage() to find the disk offsets | |
| of blocks, which in turn calls befs_fpos2brun() in datastream.c to do | |
| the hard work of finding the disk block number. | |
| * Changed method of checking for a dirty filesystem in befs_read_super | |
| (super.c). Now we check to see if log_start and log_end differ. If so, | |
| the journal needs to be replayed, and the filesystem cannot be mounted. | |
| * Fixed an extra instance of MOD_DEC_USE_COUNT in super.c | |
| * Fixed a problem with reading the superblock on devices with large sector | |
| sizes (such as cdroms) on linux 2.4.10 and up. | |
| 2001-10-24 | |
| ========== | |
| * Fix nasty bug in converting block numbers to struct befs_inode_addr. | |
| Subtle, because the old version was only sometimes wrong. | |
| Probably responsible for lots of problems. (inode.c) | |
| * Fix bug with reading an empty directory. (btree.c and dir.c) | |
| * This one looks good. Release patch version 10 | |
| 2001-10-23 | |
| ========== | |
| * Added btree searching function. | |
| * Use befs_btree_find in befs_lookup (namei.c) | |
| * Additional comments in btree.c | |
| 2001-10-22 | |
| ========== | |
| * Added B+tree reading functions (in btree.c). | |
| Made befs_readdir() use them them instead of the cruft in index.c. | |
| 2001-09-11 | |
| ========== | |
| * Converted befs_read_file() to use the new datastream code. | |
| * Finally updated the README file. | |
| * Added many comments. | |
| * Posted version 6 | |
| * Removed byte-order conversion code. | |
| I have no intention of supporting it, and it was very ugly. | |
| Flow control with #ifdef (ugh). Maybe I'll redo it once | |
| native byteorder works 100%. | |
| 2001-09-10 | |
| ========== | |
| * Finished implementing read_datastream() | |
| * made befs_read_brun() more general | |
| Supports an offset to start at and a max bytes to read | |
| Added a wrapper function to give the old call | |
| 2001-09-30 | |
| ========== | |
| * Discovered that the datastream handleing code in file.c is quite deficient | |
| in several respects. For one thing, it doesn't deal with indirect blocks | |
| * Rewrote datastream handleing. | |
| * Created io.c, for io related functions. | |
| Previously, the befs_bread() funtions lived in file.c | |
| Created the befs_read_brun() function. | |
| 2001-09-07 | |
| ========== | |
| * Made a function to actually count the number of fs blocks used by a file. | |
| And helper functions. | |
| (fs/befs/inode.c) | |
| 2001-09-05 | |
| ========== | |
| * Fixed a misunderstanding of the inode fields. | |
| This fixed the problmem with wrong file sizes from du and others. | |
| The i_blocks field of the inode struct is not the number of blocks for the | |
| inode, it is the number of blocks for the file. Also, i_blksize is not | |
| necessarily the size of the inode, although in practice it works out. | |
| Changed to blocksize of filesystem. | |
| (fs/befs/inode.c) | |
| * Permanently removed code that had been provisionally ifdefed out of befs_fs.h | |
| * Since we don't support access time, make that field zero, instead of | |
| copying m_time. | |
| (fs/befs/inode.c) | |
| * Added sanity check for inode reading | |
| Make sure inode we got was the one we asked for. | |
| (fs/befs/inode.c) | |
| * Code cleanup | |
| Local pointers to commonly used structures in inode.c. | |
| Got rid of abominations befs_iaddr2inode() and befs_inode2ino(). | |
| Replaced with single function iaddr2blockno(). | |
| (fs/befs/super.c) (fs/befs/inode.c) | |
| 2001-09-01 | |
| ========== | |
| * Fixed the problem with statfs where it would always claim the disk was | |
| half full, due to improper understanding of the statfs fields. | |
| (fs/befs/super.c) | |
| * Posted verion 4 of the patch | |
| 2001-09-01 | |
| ========== | |
| * Changed the macros in befs_fs.h to inline functions. | |
| More readable. Typesafe. Better | |
| (include/linux/befs_fs.h) | |
| * Moved type definitions from befs_fs.h to a new file, befs_fs_types.h | |
| Because befs_fs_i.h and befs_fs_sb.h were including befs_fs.h for the | |
| typedefs, and they are inlcuded in <linux/fs.h>, which has definitions | |
| that I want the inline functions in befs_fs.h to be able to see. Nasty | |
| circularity. | |
| (include/linux/befs_fs.h) | |
| 2001-08-30 | |
| ========== | |
| * Cleaned up some wording. | |
| * Added additional consitency checks on mount | |
| Check block_size agrees with block_shift | |
| Check flags == BEFS_CLEAN | |
| (fs/befs/super.c) | |
| * Tell the kernel to only mount befs read-only. | |
| By setting the SB_RDONLY flag in befs_read_super(). | |
| Not that it was possible to write before. But now the kernel won't even try. | |
| (fs/befs/super.c) | |
| * Got rid of kernel warning on mount. | |
| The kernel doesn't like it if you call set_blocksize() on a device when | |
| you have some of its blocks open. Moved the second set_blocksize() to the | |
| very end of befs_read_super(), after we are done with the disk superblock. | |
| (fs/befs/super.c) | |
| * Fixed wrong number of args bug in befs_dump_inode | |
| (fs/befs/debug.c) | |
| * Solved lots of type mismatches in kprint()s | |
| (everwhere) | |
| 2001-08-27 | |
| ========== | |
| * Cleaned up the fs/Config.in entries a bit, now slightly more descriptive. | |
| * BeFS depends on NLS, so I made activating BeFS enable the NLS questions | |
| (fs/nls/Config.in) | |
| * Added Configure.help entries for CONFIG_BEFS_FS and CONFIG_DEBUG_BEFS | |
| (currently at fs/befs/Kconfig) | |
| 2001-08-?? | |
| ========== | |
| * Removed superblock locking calls in befs_read_super(). In 2.4, the VFS | |
| hands us a super_block struct that is already locked. | |
| 2001-08-13 | |
| ========== | |
| * Will Dyson <will_dyson@pobox.com> is now attempting to maintain this module | |
| Makoto Kato <m_kato@ga2.so-net.ne.jp> is original author.Daniel Berlin | |
| also did some work on it (fixing it up for the later 2.3.x kernels, IIRC). | |
| * Fixed compile errors on 2.4.1 kernel (WD) | |
| Resolve rejected patches | |
| Accommodate changed NLS interface (util.h) | |
| Needed to include <linux/slab.h> in most files | |
| Makefile changes | |
| fs/Config.in changes | |
| * Tried to niceify the code using the ext2 fs as a guide | |
| Declare befs_fs_type using the DECLARE_FSTYPE_DEV() macro | |
| * Made it a configure option to turn on debugging (fs/Config.in) | |
| * Compiles on 2.4.7 |
