Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

1 | (Note: I consider version numbers as cheap. That means | ||
2 | that I do not like numbers like 0.1 and the like for | ||
3 | things that can be used since quite some time. But | ||
4 | then, 3.1 doesn't mean 'perfectly stable', too.) | ||
5 | |||
6 | Known bugs: | ||
7 | ----------- | ||
8 | |||
9 | - Doesn't work on the alpha. The only 64/32-bit | ||
10 | problem that I'm aware of (pointer/int conversion | ||
11 | in readdir()) gives compiler warnings but is | ||
12 | apparently not causing the failure, as directory | ||
13 | reads basically work (but all files are of size 0). | ||
14 | Alas, I've got no alpha to debug. :-( | ||
15 | |||
16 | - The partition checker (drivers/block/genhd.c) | ||
17 | doesn't work with devices which have 256 byte | ||
18 | blocks (some very old SCSI drives). | ||
19 | |||
20 | - The feature to automatically make the fs clean | ||
21 | might leave a trashed file system with the | ||
22 | bitmap flag set valid. | ||
23 | |||
24 | - When a file is truncated to a size that is not | ||
25 | a multiple of the blocksize, the rest of the | ||
26 | last allocated block is not cleared. Well, | ||
27 | this fs never claimed to be Posix conformant. | ||
28 | |||
29 | Please direct bug reports to: zippel@linux-m68k.org | ||
30 | |||

32 | ------------ | ||
33 | - kill kernel lock | ||
34 | - fix for a possible bitmap corruption | ||
35 | |||
36 | Version 3.19 | ||
37 | ------------ | ||
38 | |||
39 | - sizeof changes from Kernel Janitor Project | ||
40 | - several bug fixes found with fsx | ||
41 | |||

43 | ------------ | ||
44 | |||
45 | - change to global min macro + warning fixes | ||
46 | - add module tags | ||
47 | |||
48 | Version 3.17 | ||
49 | ------------ | ||
50 | |||
51 | - locking fixes | ||
52 | - wrong sign in __affs_hash_dentry | ||
53 | - remove unnecessary check in affs_new_inode | ||
54 | - enable international mode for dircache fs | ||
55 | |||
56 | Version 3.16 | ||
57 | ------------ | ||
58 | |||
59 | - use mark_buffer_dirty_inode instead of mark_buffer_dirty. | ||
60 | - introduce affs_lock_{link|dir|ext}. | ||
61 | |||
62 | Version 3.15 | ||
63 | ------------ | ||
64 | |||
65 | - disable link to directories until we can properly support them. | ||
66 | - locking fixes for link creation/removal. | ||
67 | |||
68 | Version 3.14 | ||
69 | ------------ | ||
70 | |||
71 | - correctly cut off long file names for compares | ||
72 | - correctly initialize s_last_bmap | ||
73 | |||
74 | Version 3.13 | ||
75 | ------------ | ||
76 | |||
77 | Major cleanup for 2.4 [Roman Zippel] | ||
78 | - new extended block handling | ||
79 | - new bitmap allocation functions | ||
80 | - locking should be safe for the future | ||
81 | - cleanup of some interfaces | ||
82 | |||
83 | Version 3.12 | ||
84 | ------------ | ||
85 | |||
86 | more 2.4 fixes: [Roman Zippel] | ||
87 | - s_lock changes | ||
88 | - increased getblock mess | ||
89 | - clear meta blocks | ||
90 | |||
91 | Version 3.11 | ||
92 | ------------ | ||
93 | |||
94 | - Converted to use 2.3.x page cache [Dave Jones <dave@powertweak.com>] | ||
95 | - Corruption in truncate() bugfix [Ken Tyler <kent@werple.net.au>] | ||
96 | |||
97 | Version 3.10 | ||
98 | ------------ | ||
99 | |||
100 | - Changed partition checker to allow devices | ||
101 | with physical blocks != 512 bytes. | ||
102 | |||
103 | - The partition checker now also ignores the | ||
104 | word at 0xd0 that Windows likes to write to. | ||
105 | |||
106 | Version 3.9 | ||
107 | ----------- | ||
108 | |||
109 | - Moved cleanup from release_file() to put_inode(). | ||
110 | This makes the first one obsolete. | ||
111 | |||
112 | - truncate() zeroes the unused remainder of a | ||
113 | partially used last block when a file is truncated. | ||
114 | It also marks the inode dirty now (which is not | ||
115 | really necessary as notify_change() will do | ||
116 | it anyway). | ||
117 | |||
118 | - Added a few comments, fixed some typos (and | ||
119 | introduced some new ones), made the debug messages | ||
120 | more consistent. Changed a bad example in the | ||
121 | doc file (affs.txt). | ||
122 | |||
123 | - Sets the NOEXEC flag in read_super() for old file | ||
124 | systems, since you can't run programs on them. | ||
125 | |||
126 | Version 3.8 | ||
127 | ----------- | ||
128 | Bill Hawes kindly reviewed the affs and sent me the | ||
129 | patches he did. They're marked (BH). Thanks, Bill! | ||
130 | |||
131 | - Cleanup of error handling in read_super(). | ||
132 | Didn't release all resources in case of an | ||
133 | error. (BH) | ||
134 | |||
135 | - put_inode() releases the ext cache only if it's | ||
136 | no longer needed. (BH) | ||
137 | |||
138 | - One set of dentry callbacks is enough. (BH) | ||
139 | |||
140 | - Cleanup of error handling in namei.c. (BH) | ||
141 | |||
142 | - Cleanup of error handling in file.c. (BH) | ||
143 | |||
144 | - The original blocksize of the device is | ||
145 | restored when the fs is unmounted. (BH) | ||
146 | |||
147 | - getblock() did not invalidate the key cache | ||
148 | when it allocated a new block. | ||
149 | |||
150 | - Removed some unnecessary locks as Bill | ||
151 | suggested. | ||
152 | |||
153 | - Simplified match_name(), changed all hashing | ||
154 | and case insensitive name comparisons to use | ||
155 | uppercase. This makes the tolower() routines | ||
156 | obsolete. | ||
157 | |||
158 | - Added mount option 'mufs' to force muFS | ||
159 | uid/gid interpretation. | ||
160 | |||
161 | - File mode changes were not updated on disk. | ||
162 | This was fixed before, but somehow got lost. | ||
163 | |||
164 | Version 3.7 | ||
165 | ----------- | ||
166 | |||
167 | - Added dentry callbacks to allow the dcache to | ||
168 | operate case insensitive and length ignorant | ||
169 | like the affs itself. | ||
170 | |||
171 | - getblock() didn't update the lastblock field in the | ||
172 | inode if the fs was not an OFS. This bug only shows | ||
173 | up if a file was enlarged via truncate() and there | ||
174 | was not enough space. | ||
175 | |||
176 | - Remove some more superfluous code left over from | ||
177 | the old link days ... | ||
178 | |||
179 | - Fixed some oversights which were in patch 2.1.78. | ||
180 | |||
181 | - Fixed a few typos. | ||
182 | |||
183 | Version 3.6 | ||
184 | ----------- | ||
185 | |||
186 | - dentry changes. (Thanks to Jes Sorensen for his help.) | ||
187 | |||
188 | - Fixed bug in balloc(): Superblock was not set dirty after | ||
189 | the bitmap was changed, so the bitmap wasn't sync'd. | ||
190 | |||
191 | - Fixed nasty bug in find_new_zone(): If the current | ||
192 | zone number was zero, the loop didn't terminate, | ||
193 | causing a solid lock-up. | ||
194 | |||
195 | - Removed support for old-style directory reads. | ||
196 | |||
197 | - Fixed bug in add_entry(): When doing a sorted insert, | ||
198 | the pointer to the next entry in the hash chain wasn't | ||
199 | correctly byte-swapped. Since most of the users of the | ||
200 | affs use it on a 68k, they didn't notice. But why did | ||
201 | I not find this during my tests? | ||
202 | |||
203 | - Fixed some oversights (version wasn't updated on some | ||
204 | directory changes). | ||
205 | |||
206 | - Handling of hard links rewritten. To the VFS | ||
207 | they appear now as normal Unix links. They are | ||
208 | now resolved only once in lookup(). The backside | ||
209 | is that unlink(), rename() and rmdir() have to | ||
210 | be smart about them, but the result is worth the | ||
211 | effort. This also led to some code cleanup. | ||
212 | |||
213 | - Changed name type to unsigned char; the test for | ||
214 | invalid filenames didn't work correctly. | ||
215 | (Thanks to Michael Krause for pointing at this.) | ||
216 | |||
217 | - Changed mapping of executable flag. | ||
218 | |||
219 | - Changed all network byte-order macros to the | ||
220 | recommended ones. | ||
221 | |||
222 | - Added a remount function, so attempts to remount | ||
223 | a dircache filesystem or one with errors read/write | ||
224 | can be trapped. Previously, ro remounts didn't | ||
225 | flush the super block, and rw remounts didn't | ||
226 | create allocation zones ... | ||
227 | |||
228 | - Call shrink_dcache_parent() in rmdir(). | ||
229 | (Thanks to Bill Hawes.) | ||
230 | |||
231 | - Permission checks in unlink(). | ||
232 | |||
233 | - Allow mounting of volumes with superfluous | ||
234 | bitmap pointers read only, also allows them | ||
235 | to be remounted read/write. | ||
236 | |||
237 | - Owner/Group defaults now to the fs user (i.e. | ||
238 | the one that mounted it) instead of root. This | ||
239 | obsoletes the mount options uid and gid. | ||
240 | |||
241 | - Argument to volume option could overflow the | ||
242 | name buffer. It is now silently truncated to | ||
243 | 30 characters. (Damn it! This kind of bug | ||
244 | is too embarrassing.) | ||
245 | |||
246 | - Split inode.c into 2 files, the superblock | ||
247 | routines desperately wanted their own file. | ||
248 | |||
249 | - truncate() didn't allocate an extension block | ||
250 | cache. If a file was extended by means of | ||
251 | truncate(), this led to an Oops. | ||
252 | |||
253 | - fsuser is now checked last. | ||
254 | |||
255 | - rename() will not ignore changes in filename | ||
256 | casing any more (though mv(1) still won't allow | ||
257 | you to do "mv oldname OldName"). | ||
258 | |||
259 | Version 3.5 | ||
260 | ----------- | ||
261 | |||
262 | - Extension block caches are now allocated on | ||
263 | demand instead of when a file is opened, as | ||
264 | files can be read and written without opening | ||
265 | them (e. g. the loopback device does this). | ||
266 | |||
267 | - Removed an unused function. | ||
268 | |||
269 | Version 3.4 | ||
270 | ----------- | ||
271 | |||
272 | - Hash chains are now sorted by block numbers. | ||
273 | (Thanks to Kars de Jong for finding this.) | ||
274 | - Removed all unnecessary external symbols. | ||
275 | |||
276 | Version 3.3 | ||
277 | ----------- | ||
278 | |||
279 | - Tried to make all types 'correct' and consistent. | ||
280 | - Errors and warnings are now reported via a | ||
281 | function. They are all prefixed by a severity | ||
282 | and have the same appearance: | ||
283 | "AFFS: <function>: <error message>" | ||
284 | (There's one exception to this, as in that function | ||
285 | is no pointer to the super block available.) | ||
286 | - The filesystem is remounted read-only after an | ||
287 | error. | ||
288 | - The names of newly created filesystem objects are | ||
289 | now checked for validity. | ||
290 | - Minor cleanups in comments. | ||
291 | - Added this Changes file. At last! | ||
292 | |||
293 | Version 3.2 | ||
294 | ----------- | ||
295 | |||
296 | - Extension block cache: Reading/writing of huge files | ||
297 | (several MB) is much faster (of course the added | ||
298 | overhead slows down opening, but this is hardly | ||
299 | noticeable). | ||
300 | - The same get_block()-routine can now be used for | ||
301 | both OFS and FFS. | ||
302 | - The super block is now searched in the block that | ||
303 | was calculated and in the one following. This | ||
304 | should remedy the round-off error introduced by | ||
305 | the 1-k blocks that Linux uses. | ||
306 | - Minor changes to adhere to the new VFS interface. | ||
307 | - The number of used blocks is now also calculated | ||
308 | if the filesystem is mounted read-only. | ||
309 | - Prefixed some constants with AFFS_ to avoid name | ||
310 | clashes. | ||
311 | - Removed 'EXPERIMENTAL' status. | ||
312 | |||
313 | Version 3.1 | ||
314 | ----------- | ||
315 | |||
316 | - Fixed a nasty bug which didn't allow read-only | ||
317 | mounts. | ||
318 | - Allow dir-cache filesystems to be mounted | ||
319 | read only. | ||
320 | - OFS support. | ||
321 | - Several other changes I just cannot remember | ||
322 | any more. | ||
323 | |||
324 | Version 3.0 | ||
325 | ----------- | ||
326 | |||
327 | - Almost complete rewrite for the new VFS | ||
328 | interface in Linux 1.3. | ||
329 | - Write support. | ||
330 | - Support for hard and symbolic links. | ||
331 | - Lots of things I remember even less ... | ||
332 | |||
333 | Version 2.0 | ||
334 | ----------- | ||
335 | |||
336 | - Fixed a few things to get it compiled. | ||
337 | - Automatic root block calculation. | ||
338 | - Partition checker for genhd.c | ||
339 | |||
340 | ======================================== | ||
341 | |||
342 | Let's just call Ray Burr's original affs | ||
343 | 'Version 1.0'. | ||
