1 FUSE 2.9.9 (2019-01-04)
2 =======================
4 * Added OpenAFS to whitelist (so users can now mount FUSE filesystems
5 on mountpoints within OpenAFS filesystems).
6 * Added a test of `seekdir` to test_syscalls.
7 * Fixed `readdir` bug when non-zero offsets are given to filler and the
8 filesystem client, after reading a whole directory, re-reads it from a
9 non-zero offset e. g. by calling `seekdir` followed by `readdir`.
11 FUSE 2.9.8 (2018-07-24)
12 =======================
14 * SECURITY UPDATE: In previous versions of libfuse it was possible to
15 for unprivileged users to specify the `allow_other` option even when
16 this was forbidden in `/etc/fuse.conf`. The vulnerability is
17 present only on systems where SELinux is active (including in
19 * libfuse no longer segfaults when fuse_interrupted() is called outside
21 * The fusermount binary has been hardened in several ways to reduce
22 potential attack surface. Most importantly, mountpoints and mount
23 options must now match a hard-coded whitelist. It is expected that
24 this whitelist covers all regular use-cases.
25 * Fixed rename deadlock on FreeBSD.
27 FUSE 2.9.7 (2016-06-20)
28 =======================
30 * Added SELinux support.
31 * Fixed race-condition when session is terminated right after starting
34 FUSE 2.9.6 (2016-04-23)
35 =======================
37 * Tarball now includes documentation.
38 * Shared-object version has now been bumped correctly.
40 FUSE 2.9.5 (2016-01-14)
41 =======================
43 * New maintainer: Nikolaus Rath <Nikolaus@rath.org>. Many thanks to
44 Miklos Szeredi <miklos@szeredi.hu> for bringing FUSE to where it is
47 * fix warning in mount.c:receive_fd(). Reported by Albert Berger
49 * fix possible memory leak. Reported by Jose R. Guzman
51 FUSE 2.9.4 (2015-05-22)
52 =======================
54 * fix exec environment for mount and umount. Found by Tavis Ormandy
57 * fix fuse_remove_signal_handlers() to properly restore the default
58 signal handler. Reported by: Chris Johnson
60 * highlevel API: fix directory file handle passed to ioctl() method.
61 Reported by Eric Biggers
63 * libfuse: document deadlock avoidance for fuse_notify_inval_entry()
64 and fuse_notify_delete()
66 * fusermount, libfuse: send value as unsigned in "user_id=" and
67 "group_id=" options. Uids/gids larger than 2147483647 would result
68 in EINVAL when mounting the filesystem. This also needs a fix in
71 * Initilaize stat buffer passed to ->getattr() and ->fgetattr() to
72 zero in all cases. Reported by Daniel Iwan
74 * libfuse: Add missing includes. This allows compiling fuse with
75 musl. Patch by Daniel Thau
78 Older Versions (before 2013-01-01)
79 ==================================
82 2013-06-20 Miklos Szeredi <miklos@szeredi.hu>
84 * libfuse: fix multiple close of device fd. Reported by Dan
87 2013-03-19 Miklos Szeredi <miklos@szeredi.hu>
89 * libfuse: fix thread cancel race. Exiting a worker my race with
90 cancelling that same worker. This caused a segmenation
91 fault. Reported and tested by Anatol Pomozov
93 2013-02-04 Miklos Szeredi <miklos@szeredi.hu>
95 * libfuse: fix crash in unlock_path(). Patch by Ratna Manoj
97 * libfuse: fix the 'remember' option. The lru list was not
98 initialized for the "/" path. This resulted in remove_node_lru()
99 crashing on LOOKUP-DOTDOT. Patch by Madan Valluri
101 * libfuse: configure: detect new util-linux
103 * libfuse: Use AC_CONFIG_HEADERS instead of AM_CONFIG_HEADER.
104 Patch by Anatol Pomozov
106 * libfuse: rename ./configure.in to ./configure.ac. Patch by
109 2012-10-01 Miklos Szeredi <miklos@szeredi.hu>
113 2012-10-01 Miklos Szeredi <miklos@szeredi.hu>
115 * Fix deadlock in libfuse. Running "svn update" on a fuse
116 filesystem could deadlock because of a bug in the way the paths
117 are locked. Reported by Kazuaki Anami
119 2012-08-23 Miklos Szeredi <miklos@szeredi.hu>
121 * Fix missing config.h in buffer.c. Reported by Matthew Gabeler-Lee
123 2012-08-14 Miklos Szeredi <miklos@szeredi.hu>
125 * Not unhashing the name in forget (commit on 2011-12-09) broke
126 the forget logic in a subtle way, resulting in "fuse internal
127 error: node NNN not found" and causing the filesystem daemon to
128 abort. Fix by incrementing the node refcount if nlookup goes from
129 zero to one. Reported by Kyle Lippincott
131 2012-08-13 Miklos Szeredi <miklos@szeredi.hu>
133 * Fix linking against GNU libiconv. Patch by Natanael Copa
135 2012-07-19 Miklos Szeredi <miklos@szeredi.hu>
139 2012-07-19 Miklos Szeredi <miklos@szeredi.hu>
141 * Fix crash caused by freeing a stack address. Reported by Itay
144 2012-07-04 Miklos Szeredi <miklos@szeredi.hu>
146 * Fix install of mount.fuse from out-of-tree build. Patch by
149 * Fix build with automake >= 1.12.1. Patch by Olivier Blin
151 2012-04-24 Miklos Szeredi <miklos@szeredi.hu>
153 * Add fallocate operation. Only works on linux kernels 3.5 or
154 later. Patch by Anatol Pomozov
156 2012-05-16 Miklos Szeredi <miklos@szeredi.hu>
158 * Linking to a library that uses threads requires the application
159 to be linked with -pthreads otherwise some pthread functions will
160 be linked to stubs in glibc. So move -pthread from Libs.private
161 to Libs in fuse.pc. Reported by Werner Fink
163 * Fix the compile command in the examples. Reported by Luciano
166 2012-04-20 Miklos Szeredi <miklos@szeredi.hu>
170 2012-04-20 Miklos Szeredi <miklos@szeredi.hu>
172 * Add missing fuse_fs_flock to fuse_versionscript
174 2012-04-10 Miklos Szeredi <miklos@szeredi.hu>
176 * Check protocol version before sending notifications and return
177 -ENOSYS if a particular notification is not supported.
179 * Add 'flag_utime_omit_ok' flag to fuse_operations. If the
180 filesystem sets this flag then ->utimens() will receive UTIME_OMIT
181 and UTIME_NOW values as specified in utimensat(2).
183 2012-01-27 Miklos Szeredi <miklos@szeredi.hu>
185 * Interpret octal escape codes in options. Requested by Jan
188 2012-01-26 Miklos Szeredi <miklos@szeredi.hu>
190 * Add man pages for fusermount, mount.fuse and ulockmgr_server.
191 Lifted from the Debian package. The man pages were written by
192 Daniel Baumann and Bastien Roucaries
194 2012-01-13 Miklos Szeredi <miklos@szeredi.hu>
196 * Disable symbol versions on MacOSX. Patch by Anatol Pomozov
198 2012-01-02 Miklos Szeredi <miklos@szeredi.hu>
200 * Remove unnecessary mutex unlock at the end of multithreaded
203 2011-12-09 Miklos Szeredi <miklos@szeredi.hu>
205 * Fix hang in wait_on_path(). Reported by Ville Silventoinen
207 * Don't unhash name in FORGET. This resulted in ENOENT being
208 returned for unlinked but still open files if the kernel sent a
209 FORGET request for the parent directory.
211 * Free request in fuse_reply_data().
213 2011-12-08 Miklos Szeredi <miklos@szeredi.hu>
215 * Fix build if FUSE_NODE_SLAB is not defined. Patch by Emmanuel
218 * Check for availability of utimensat() function. Patch by
221 2011-12-07 Miklos Szeredi <miklos@szeredi.hu>
223 * Add fuse_lowlevel_notify_delete() which tells the kernel that a
224 file or directory is deleted. Patch by John Muir
226 2011-12-06 Miklos Szeredi <miklos@szeredi.hu>
228 * Update retrieve_reply() method
230 2011-12-05 Miklos Szeredi <miklos@szeredi.hu>
232 * Low level API: lock argument of fuse_reply_lock should have a
233 'const' qualifier. Reported by Shachar Sharon
235 * Add support for ioctl on directories. Reported by Antonio SJ
238 2011-10-13 Miklos Szeredi <miklos@szeredi.hu>
240 * Reply to request with ENOMEM in case of failure to allocate
241 request structure. Otherwise the task issuing the request will
242 just freeze up until the filesystem daemon is killed. Reported by
245 2011-09-23 Miklos Szeredi <miklos@szeredi.hu>
247 * Replace daemon() function with fork(). Patch by Anatol Pomozov
249 2011-08-26 Miklos Szeredi <miklos@szeredi.hu>
251 * If configured with --disable-mtab then don't call mount(8) from
252 libfuse to update the mtab. Reported by: James Sierp
254 2011-08-24 Miklos Szeredi <miklos@szeredi.hu>
256 * Use LRU list for cleaning up the cache if the "remember=T"
257 option was given. Patch by therealneworld@gmail.com
259 2011-07-06 Miklos Szeredi <miklos@szeredi.hu>
261 * Add ->flock() operation to low and high level interfaces. This
262 fixes problems with emulating flock() with POSIX locking.
263 Reported by Sebastian Pipping. As with lock/setlk/getlk most
264 filesystems don't need to implement this, as the kernel takes care
265 of file locking. The only reason to implement locking operations
266 is for network filesystems which want file locking to work between
269 2011-07-02 Sebastian Pipping <sebastian@pipping.org>
271 * Make xmp_utimens of examples "fusexmp" and "fusexmp_fh"
272 not follow symlinks as other layers do that already.
274 2011-06-02 Miklos Szeredi <miklos@szeredi.hu>
276 * Add "remember" option. This works similar to "noforget" except
277 that eventually the node will be allowed to expire from the cache.
278 Patch by therealneworld@gmail.com
280 2011-05-27 Miklos Szeredi <miklos@szeredi.hu>
282 * Check if splice/vmsplice are supported
284 2011-05-26 Miklos Szeredi <miklos@szeredi.hu>
286 * Remove -lrt -ldl from fuse.pc for dynamic linking since
287 libfuse.so is already linked with these libraries. Reported by:
290 2011-05-20 Miklos Szeredi <miklos@szeredi.hu>
292 * Cleaner build output. Patch by Reuben Hawkins
294 2011-05-19 Miklos Szeredi <miklos@szeredi.hu>
296 * Disable splice by default, add "splice_read", "splice_write" and
297 "splice_move" options. Keep the "no_splice_*" variants, which can
298 disable splice even if the filesystem explicitly enables it.
300 2011-04-15 Max Krasnyansky <maxk@kernel.org>
301 * Added support for "auto_unmount" option which unmounts the
302 filesystem automatically on process exit (or crash).
304 2011-03-30 Miklos Szeredi <miklos@szeredi.hu>
306 * Patches by Laszlo Papp fixing various issues found by the
309 2011-03-11 Miklos Szeredi <miklos@szeredi.hu>
311 * In case of failure to add to /etc/mtab don't umount. Reported
314 2011-02-02 Miklos Szeredi <miklos@szeredi.hu>
316 * libfuse: In fuse_session_loop_mt() don't pause when exiting the
317 worker threads. The pause() was added in 2.2.1 to prevent
318 segfault on pthread_cancel() on an exited, detached thread. Now
319 worker threads are not detached and pthread_cancel() should work
320 fine even after the thread exited. Reported by Boris Protopopov
322 2011-01-31 Miklos Szeredi <miklos@szeredi.hu>
324 * fusermount: chdir to / before performing mount/umount
326 * fusermount: only allow mount and umount if util-linux supports
329 2010-12-16 Miklos Szeredi <miklos@szeredi.hu>
331 * Highlevel lib: allow hash tables to shrink
333 * Highlevel lib: add slab allocation for node cache. This will
334 allow the memory used by the filesystem to grow and shrink
335 depending on how many inodes are currently cached.
337 2010-12-13 Miklos Szeredi <miklos@szeredi.hu>
339 * Highlevel lib: use dynamically resized hash table for looking up
342 2010-12-07 Miklos Szeredi <miklos@szeredi.hu>
344 * Allow batching of forget requests. This allows forget requests
345 to be processed faster and doesn't require a modification to fuse
346 filesystems. Reported by Terje Malmedal
348 * Add ->forget_multi() operation to the lowlevel API. The
349 filesystem may implement this to process multiple forget requests
352 * Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
353 for 32bit vs. 64bit userspace
355 2010-11-10 Miklos Szeredi <miklos@szeredi.hu>
357 * Add new write_buf() method to the highlevel API. Similarly to
358 the lowlevel write_buf() method, this allows implementing zero
361 * Add a new read_buf() method to the highlevel API. This allows
362 returning a generic buffer from the read method, which in turn
363 allows zero copy reads.
365 * In fusexmp_fh implement the ->read_buf() and ->write_buf()
366 methods. Leave the ->read() and ->write() implementations for
367 reference, even though they are not necessary.
369 2010-11-08 Miklos Szeredi <miklos@szeredi.hu>
371 * Fix check for read-only fs in mtab update
373 * Open /dev/null for write instead of read for redirecting stdout
376 * If umount(8) supports --fake and --no-canonicalize (util-linux-ng
377 version 2.18 or later), and umount(2) supports the
378 UMOUNT_NOFOLLOW flag (linux kernel version 2.6.35 or later) then,
379 "fusermount -u" will call the umount(2) system call and use
380 "umount --fake ..." to update /etc/mtab
382 * Added --disable-legacy-umount option to configure. This
383 disables the runtime checking of umount(8) version. When built
384 with this option then "fusermount -u" will fail if umount(8)
385 doesn't support the --fake and --no-canonicalize options.
387 * Fix fuse_buf_copy() if already at the end of the buffers
389 * Add new ->write_buf() method to low level interface. This
390 allows passig a generic buffer, either containing a memory buffer
391 or a file descriptor. This allows implementing zero copy writes.
393 * Add fuse_session_receive_buf() and fuse_session_process_buf()
394 which may be used in event loop implementations to replace
395 fuse_chan_recv() and fuse_session_process() respectively.
397 * Remove unnecessary restoring of current working directory in
400 * Add ctx->pid to debug output
402 * Fix st_nlink value in high level lib if file is unlinked but
405 * libfuse: add store request. Request data to be stored in the
406 kernel buffers for a given inode.
408 * libfuse: add retrieve request. Retrieve data stored in the
409 kernel buffers for a given inode.
411 2010-10-14 Miklos Szeredi <miklos@szeredi.hu>
413 * Use LTLIBICONV when linking libfuse. This fixes building against
414 uclibc + libiconv. Patch by Natanael Copa
416 2010-10-05 Miklos Szeredi <miklos@szeredi.hu>
418 * Add missing argument check in ulockmgr.c to prevent calling
419 ulockmgr_server with illegal arguments. This would cause an ever
420 growing list of ulockmgr_server processes with an endless list of
421 open files which finally exceeds the open file handle limit.
422 Patch by Markus Ammer
424 2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
426 * Fix ambiguous symbol version for fuse_chan_new.
427 fuse_versionscript included fuse_chan_new in both FUSE_2.4 and
428 FUSE_2.6. Remove the FUSE_2.4, which is invalid.
430 2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
432 * Fix option escaping for fusermount. If the "fsname=" option
433 contained a comma then the option parser in fusermount was
434 confused (Novell bugzilla #641480). Fix by escaping commas when
435 passing them over to fusermount. Reported by Jan Engelhardt
437 2010-08-27 Miklos Szeredi <miklos@szeredi.hu>
439 * Add NetBSD support. Patch from Emmanuel Dreyfus
441 2010-07-12 Miklos Szeredi <miklos@szeredi.hu>
443 * libfuse: add buffer interface. Add a generic buffer interface
444 for use with I/O. Buffer vectors are supplied and each buffer in
445 the vector may be a memory pointer or a file descriptor.
447 * The fuse_reply_fd() interface is converted to using buffers.
449 2010-06-23 Miklos Szeredi <miklos@szeredi.hu>
451 * Make the number of max background requests and congestion
452 threshold tunable. New options are "max_background" and
453 "congestion_threshold". Only effective on linux kernel versions
454 2.6.32 or greater. Patch by Csaba Henk
456 2010-06-17 Miklos Szeredi <miklos@szeredi.hu>
458 * Add fuse_reply_fd() reply function to the low level interface.
459 On linux version 2.6.35 or greater this will use splice() to move
460 data directly from a file descriptor to the fuse device without
461 needing to go though a userspace buffer. With the
462 FUSE_REPLY_FD_MOVE flag the kernel will attempt to move the data
463 directly into the filesystem's cache. On earlier kernels it will
464 fall back to an intermediate buffer. The options
465 "no_splice_write" and "no_splice_move" can be used to disable
466 splicing and moving respectively.
468 2010-06-15 Miklos Szeredi <miklos@szeredi.hu>
470 * Fix out-of-source build. Patch by Jörg Faschingbauer
472 * Add a "nopath" option and flag, indicating that path argument
473 need not be calculated for the following operations: read, write,
474 flush, release, fsync, readdir, releasedir, fsyncdir, ftruncate,
475 fgetattr, lock, ioctl and poll.
477 2010-05-10 Miklos Szeredi <miklos@szeredi.hu>
479 * Remove "chmod root" from install of fusermount. Reported by
482 2010-04-26 Miklos Szeredi <miklos@szeredi.hu>
486 2010-04-26 Miklos Szeredi <miklos@szeredi.hu>
488 * Fix checking for symlinks in umount from /tmp. Reported by Al
491 * Fix umounting if /tmp is a symlink. Reported by Franco Broi
493 2010-02-18 Miklos Szeredi <miklos@szeredi.hu>
495 * Fix definition of FUSE_OPT_END for C++. Reported by Tim
498 2010-02-03 Miklos Szeredi <miklos@szeredi.hu>
500 * Fix stack alignment for clone()
502 2010-02-01 Miklos Szeredi <miklos@szeredi.hu>
506 2010-02-01 Miklos Szeredi <miklos@szeredi.hu>
508 * Using "--no-canonicalize" with umount(8) conflicts with the race
509 fix, sinceit assumes the supplied path is absolute, while the race
510 fix relies on the path being relative to the current directory.
511 Reported by Tom Rindborg
513 2010-01-26 Miklos Szeredi <miklos@szeredi.hu>
517 2010-01-21 Miklos Szeredi <miklos@szeredi.hu>
519 * Fix race if two "fusermount -u" instances are run in parallel.
520 Reported by Dan Rosenberg
522 * Make sure that the path to be unmounted doesn't refer to a
525 2010-01-14 Miklos Szeredi <miklos@szeredi.hu>
527 * Fix compile error on FreeBSD. Patch by Jay Sullivan
529 2009-12-17 Miklos Szeredi <miklos@szeredi.hu>
531 * Use '--no-canonicalize' option of mount(8) (available in
532 util-linux-ng version 2.17 or greater) to avoid calling
533 readling(2) on the newly mounted filesystem before the mount
534 procedure is finished. This has caused a deadlock if "audit" was
535 enabled in the kernel. Also use '--no-canonicalize' for umount to
536 avoid touching the mounted filesystem.

542 2009-08-25 Miklos Szeredi <miklos@szeredi.hu>
544 * Fix missing versioned symbol fuse_get_context@FUSE_2.2
546 2009-08-18 Miklos Szeredi <miklos@szeredi.hu>
550 2009-08-18 Miklos Szeredi <miklos@szeredi.hu>
552 * Add missing fuse_session_data to versionscript
554 * Make sure all global symbols are prefixed with "fuse_" or "cuse_"
556 2009-07-16 Miklos Szeredi <miklos@szeredi.hu>
558 * Clarify how the protocol version should be negotiated between
559 kernel and userspace. Notably libfuse didn't correctly handle the
560 case when the supported major versions didn't match
562 * Add missing pthread link for libulockmgr. Patch by Petr Salinger
564 2009-07-02 Miklos Szeredi <miklos@szeredi.hu>
566 * The context is extended with a 'umask' field. The umask is sent
567 for mknod, mkdir and create requests by linux kernel version
568 2.6.31 or later, otherwise the umask is set to zero. Also
569 introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel
570 supports this feature, then this flag will be set in conn->capable
571 in the ->init() method. If the filesystem sets this flag in in
572 conn->want, then the create modes will not be masked.
574 * Add low level interfaces for lookup cache and attribute
575 invalidation. This feature is available in linux kernels 2.6.31
576 or later. Patch by John Muir
578 * Kernel interface version is now 7.12
580 * fusermount: Do not silently ignore command line arguments.
581 Patch by Sebastian Harl
583 2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
585 * Released 2.8.0-pre3
587 2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
589 * Add fuse_getgroups (high level lib) and fuse_req_getgroups (low
590 level lib) functions to query the supplementary group IDs for the
591 current request. Currently this is implemented on Linux by
592 reading from the /proc filesystem.
594 2009-06-18 Miklos Szeredi <miklos@szeredi.hu>
596 * Add "noforget" option to high level lib to prevent ESTALE errors
597 on NFS exported filesystems. This result in paths being cached
598 forever, resulting in ever growing memory usage. Use with care.
600 * Add "no_remote_lock" option to disable remote file locking even
601 if the filesystem implements it. With this option locking
602 primitives (flock, lockf, fcntl(F_SETLK)) will still work, but
603 will ignore remotely locked files.
605 * CUSE patches from Tejun Heo:
607 * Unrestricted ioctl support left some debris. Clean them up:
608 o No reason to pass around pointer to flags. Pass flags directly.
609 o Clean up comment and prototype parameter names.
610 o fuse_lib_ioctl() didn't reply when get_path() failed. Fix it.
611 o Remove unused variables {in|out}_iov from fuse_lib_ioctl().
613 * Add fuse_reply_ioctl_iov()
615 * Move fuse_session, fuse_req and fuse_ll definitions to fuse_i.h
616 and make send_reply_iov() and fuse_setup_common() global (also in
617 fuse_i.h). These will be used by CUSE support.
619 * Restructure fuse_ll_process()
621 * Implement libfuse side of CUSE support. CUSE uses subset of FUSE
622 operations as dir operations don't make sense for CUSE where one
623 instance implements single character device.
625 CUSE support comes with its own cuse_lowevel_ops and related
626 initialization and helper functions. Except for initialization, it
627 usage is basically identical to FUSE.
629 This patch also adds example/cusexmp.c which can create a character
630 device with name and device number specified on command line. The
631 created device itself is pretty boring. It's a bit bucket supporting
632 read, write and access via ioctl.
634 2009-06-16 Miklos Szeredi <miklos@szeredi.hu>
636 * Add missing fuse_reply_bmap to versionscript. Debian
637 Bug#531329. Reported by Goswin Brederlow
639 2009-05-27 Miklos Szeredi <miklos@szeredi.hu>
641 * Don't call forget_node() if the lookup was negative and write()
642 for the reply returned ENOENT. Reported by John Haxby
644 2009-05-25 Miklos Szeredi <miklos@szeredi.hu>

656 * Released 2.8.0-pre2
658 2008-12-08 Miklos Szeredi <miklos@szeredi.hu>
660 * Implement poll support. Patch by Tejun Heo
662 * Add missing setattr flags to <fuse_lowlevel.h>.
664 * Only pass valid flags to ->setattr().
666 2008-12-05 Miklos Szeredi <miklos@szeredi.hu>
668 * Implement ioctl support. On high level interface only
669 "restricted" ioctls are supported (which are defined with the
670 _IO(), _IOR(), _IOW() or _IOWR() macros). Unrestricted ioctls
671 will only be allwed to CUSE (Character Device in Userspace)
672 servers. Patch by Tejun Heo
674 2008-11-28 Miklos Szeredi <miklos@szeredi.hu>
676 * If open sets fi->nonseekable, libfuse will tell the kernel that
677 the file is not seekable. Patch by Tejun Heo
679 2008-11-19 Miklos Szeredi <miklos@szeredi.hu>
681 * lowlevel lib: fix deadlock if fuse_reply_* is called from the

706 * Fix handling of (no)suid and (no)dev options if filesystem is
707 mounted from /etc/fstab or via mount(8). Reported by Jan Ondrej.
709 * Skip calling mount(8) if /etc/mtab doesn't exist or if it's on a
710 read-only filesystem. This works around issues with certain mount
711 implementations. Reported by Szabolcs Szakacsits.
713 2008-06-16 Miklos Szeredi <miklos@szeredi.hu>
715 * Remove fuse kernel module sources. Linux 2.6.27 will support
718 2008-06-10 Miklos Szeredi <miklos@szeredi.hu>
720 * Fix theoretical infinite loops in libfuse. Reported by Szabolcs

728 * Fix mounting over symlink. Reported by Szabolcs Szakacsits
730 2008-05-09 Miklos Szeredi <miklos@szeredi.hu>
732 * Don't allow bigger than 4kB writes by default on 2.6.26 and
733 later kernels, so that filesystems not expecting this are not
734 broken on a kernel upgrade. Provide a 'big_writes' mount option
735 to enable this feature. In future API revisions this may become
738 2008-04-09 Miklos Szeredi <miklos@szeredi.hu>
740 * Update warning message for missing newline at end of fuse.conf
742 * Update debug message for successful operation to not include the
745 2008-04-08 Miklos Szeredi <miklos@szeredi.hu>

756 2008-03-25 Miklos Szeredi <miklos@szeredi.hu>
758 * Fix memory leaks on mount. Patch by Szabolcs Szakacsits
760 2008-03-19 Miklos Szeredi <miklos@szeredi.hu>
762 * Fix missing pthread_mutex_destroy in error path of
763 fuse_lib_opendir(). Patch by Szabolcs Szakacsits
765 2008-03-07 Miklos Szeredi <miklos@szeredi.hu>
767 * Add queuing on contention to per-node lock algorithm, to avoid
770 * Only enable cancelation when reading a request, otherwise
771 cancellation could happen with a mutex held, which could hang the
774 2008-02-08 Miklos Szeredi <miklos@szeredi.hu>

782 * Support receiving file handle from kernel in GETATTR request
784 * Allow operations with a NULL path argument, if the filesystem
787 * Add support atomic open(O_TRUNC)
789 * Support the st_blksize field in struct stat
791 * If the "FUSE_THREAD_STACK" environment is set, initialize the
792 stack size of threads by this value. Patch by Florin Malita
794 * Add per-node locking, instead of a global tree lock to protect
795 the path from changing during operations. Original patch by
798 2008-02-03 Csaba Henk <csaba.henk@creo.hu>
801 - string formatting fixes
802 - exit if mounting has failed
803 (in FreeBSD a mount failure is not critical per se, as the daemon
804 still could be mounted externally, but waiting for such an event
805 is more confusing than fruitful)
806 - ditch the kvm(8) stuff and simply use forced unmount which just
808 - prettify option specifications
809 - add "-onosync_unmount" kernel option
811 2008-01-07 Csaba Henk <csaba.henk@creo.hu>
814 - refine device closing in a race-free way
815 - add support for "-osubtype" on FreeBSD
817 * makeconf.sh: make it work under FreeBSD
819 2008-01-03 Csaba Henk <csaba.henk@creo.hu>
821 * lib/mount_bsd.c: close device before unmount
822 (cf. lib/mount.c rev. 1.43) and fix some warnings
824 2007-12-23 Miklos Szeredi <miklos@szeredi.hu>
826 * Fix './configure --disable-static'. Patch from Ismail Dönmez
828 2007-12-17 Miklos Szeredi <miklos@szeredi.hu>
832 2007-12-12 Miklos Szeredi <miklos@szeredi.hu>
834 * Fix kernel module compile for 2.6.24
836 * Invalidate attributes of parent directory after create(), since
837 the modification time changes. Invalidate attributes on rename,
838 since some filesystems may update st_ctime. Reported by Szabolcs
841 * Fix NFS exporting to handle 64bit node IDs
843 * Disable old symbol versions if __UCLIBC__ is defined. If a
844 symbol in a library has multiple versions, the runtime linker in
845 uClibc seems to randomly choose between them.
847 * Remove erroneous 'fuse_opt_insert_arg@FUSE_2_5' from
848 fuse_version_script. fuse_opt_free_args() was added in fuse-2.6.
850 * Close fuse device file descriptor before calling umount(),
851 preventing a deadlock when umount is synchronous. Reported by
854 2007-11-12 Miklos Szeredi <miklos@szeredi.hu>
856 * 'fusermount -u' did not umount the filesystem if /etc/mtab was a
857 symlink. This bug was introduced in 2.7.1 by "Don't call
858 /bin/[u]mount if /etc/mtab is a symlink". Found by robertsong.

886 * lib/fuse_lowlevel.c: fix a fuse_req leak in do_forget()
888 2007-07-31 Miklos Szeredi <miklos@szeredi.hu>
890 * Work around hotplug issue, that it calls filesystem with file
891 descriptors 0, 1 and 2 not open. Tracked down by Leif Johnson
893 2007-07-25 Miklos Szeredi <miklos@szeredi.hu>
895 * Don't call /bin/[u]mount if /etc/mtab is a symlink. Reported by
898 * Also don't touch /etc/mtab if it is within the mounted
899 filesystem. Suggested by Jeffrey Law
901 2007-07-12 Miklos Szeredi <miklos@szeredi.hu>
903 * Reset args->argc in fuse_opt_free_args(). Patch by Lucas
906 2007-07-02 Miklos Szeredi <miklos@szeredi.hu>
910 2007-07-02 Miklos Szeredi <miklos@szeredi.hu>
912 * Accept a NULL "op" for fuse_main(), etc. This is useful if
913 filesystem is only invoking fuse to print a help message, or
914 version. Fixes RedHat bugzilla #217343
916 2007-06-22 Miklos Szeredi <miklos@szeredi.hu>
918 * lib: fix locking when loading a filesystem module
920 2007-06-21 Miklos Szeredi <miklos@szeredi.hu>
922 * Add fs subtype support to mount.fuse

926 * Add fs subtype support to libfuse and fusermount
928 2007-06-19 Miklos Szeredi <miklos@szeredi.hu>
930 * kernel: sync with mainline (2.6.22)
932 2007-06-18 Miklos Szeredi <miklos@szeredi.hu>
934 * Send debug output to stderr instead of stdout. Patch by Jan
937 2007-06-03 Miklos Szeredi <miklos@szeredi.hu>
939 * libulockmgr: Work around a kernel bug in recv(), causing it to
940 sometimes return zero even if data was available on the socket.
942 2007-05-29 Miklos Szeredi <miklos@szeredi.hu>
944 * lib: optimization: store parent pointer in node instead of
947 2007-05-25 Miklos Szeredi <miklos@szeredi.hu>
949 * lib: don't create new thread for each FORGET request. FORGET
950 messages sometimes caused so many threads to be created, that
951 process virtual memory space ran out. Reported by Chris AtLee
953 2007-05-24 Miklos Szeredi <miklos@szeredi.hu>
955 * lib: fix memory leak on thread creation failure in multithreaded
956 event loop. Found by Chris AtLee
958 2007-05-23 Miklos Szeredi <miklos@szeredi.hu>
960 * lowlevel lib: add fuse_reply_iov function, which is similar to
961 fuse_reply_buf, but accepts a vector of buffers. Patch by Roger
964 2007-05-21 Miklos Szeredi <miklos@szeredi.hu>
966 * Fix Oops or error if a regular file is created with mknod(2) on
967 a fuse filesystem. Kernels 2.6.18 onward are affected. Thanks to
968 J. Cameijo Cerdeira for the report
970 2007-05-11 Csaba Henk <csaba.henk@creo.hu>
972 * libfuse: fix return value of fuse_loop()/fuse_loop_mt().
973 Error reported by Csaba Henk, fix by Miklos Szeredi

983 2007-05-02 Miklos Szeredi <miklos@szeredi.hu>
985 * kernel: sync with mainline:
987 * Use invalidate_mapping_pages() if available
989 * Fix BUG when invalid file type is supplied in mount. Patch by
992 2007-04-27 Miklos Szeredi <miklos@szeredi.hu>
994 * libfuse: call umount(8) directly instead of fusermount if
997 * Clean up init script, make it LSB compliant
999 2007-04-26 Miklos Szeredi <miklos@szeredi.hu>
1001 * In multithreaded loop, use a semaphore instead of SIGHUP to wake
1002 up the main thread on umount. This is more elegant, and works
1003 even if signals are blocked.
1005 2007-04-25 Miklos Szeredi <miklos@szeredi.hu>
1007 * Improve mounting support in libfuse:
1008 - check non-empty mountpoint
1009 - only fall back to fusermount when necessary
1011 2007-04-23 Miklos Szeredi <miklos@szeredi.hu>
1013 * Don't chdir to "/" in foreground mode, it causes more trouble
1016 2007-04-18 Miklos Szeredi <miklos@szeredi.hu>
1018 * Replace utils/mount.fuse "sh" script with a "C" program

1026 * Check for iconv. Patch by Csaba Henk
1028 * Add direct umounting
1030 * Use "fusectl" as the device for the fusectl filesystem. Debian
1031 Bug#417945. Reported by Laurent Bonnaud
1033 2007-04-01 Csaba Henk <csaba.henk@creo.hu>
1035 * Fix some FreeBSD related macros.
1037 2007-03-30 Miklos Szeredi <miklos@szeredi.hu>
1039 * Add support for direct mounting by libfuse. Fall back on
1040 calling fusermount if it doesn't work
1042 2007-03-14 Miklos Szeredi <miklos@szeredi.hu>
1044 * Released 2.7.0-pre1
1046 2007-03-05 Miklos Szeredi <miklos@szeredi.hu>
1048 * Correctly handle O_APPEND in direct IO mode. Reported by Greg
1051 * mount.fuse should use /bin/bash. Debian Bug#413403. Reported
1052 by Thomas Weinbrenner
1054 2007-02-26 Miklos Szeredi <miklos@szeredi.hu>
1056 * Fix detection of installed fuse in init script. Reported and
1057 fix suggested by Davide Canova
1059 2007-02-05 Miklos Szeredi <miklos@szeredi.hu>
1061 * Fix 2.6.9 RHEL kernels, which have compatibility mutex.h, but
1062 don't define mutex_destroy(), bummer. Patch from Phil Schwan
1064 2007-02-04 Miklos Szeredi <miklos@szeredi.hu>
1066 * Compile fuseblk for kernels which don't have an option to turn
1067 off the block layer (CONFIG_BLOCK). Reported by Szakacsits
1070 2007-02-03 Miklos Szeredi <miklos@szeredi.hu>
1072 * Add filesystem stacking support to high level API. Filesystem
1073 modules can be built into libfuse or loaded from shared object
1076 * Add 'subdir' and 'iconv' built in modules
1078 * lib/fuse.c: Fix locking for the reply code in create and open
1080 2007-02-02 Miklos Szeredi <miklos@szeredi.hu>
1082 * kernel: make it compile on "strange" kernels which have emulated
1083 mutexes via <linux/mutex.h> but no i_mutex. Reported by Tomasz
1086 2007-01-28 Miklos Szeredi <miklos@szeredi.hu>
1088 * kernel: fix BUG in control filesystem if it is umounted and
1089 mounted again, while some fuse filesystems are present.
1090 Bugreport from Florent Mertens
1092 * kernel: sync with mainline, support 2.6.20
1094 2007-01-22 Miklos Szeredi <miklos@szeredi.hu>
1096 * lib/Makefile.am: actually link libfuse against libfuse_libs
1098 2007-01-19 Miklos Szeredi <miklos@szeredi.hu>
1100 * Build fix for 2.6.16 vanila and 2.6.15 FC5 kernels. Patch from
1103 2007-01-18 Miklos Szeredi <miklos@szeredi.hu>
1105 * Fix abort in fuse_new() compatibility API for opts == NULL case.
1106 Novell bugzilla #233870. Patch from Takashi Iwai.
1108 2007-01-13 Miklos Szeredi <miklos@szeredi.hu>
1110 * Fix option parsing in mount.fuse. Patch from Jens M. Noedler
1112 2007-01-02 Miklos Szeredi <miklos@szeredi.hu>
1114 * Fix unaligned access in file desctriptor passing in libfuse,
1115 fusermount and ulockmgr. Debian bug ID: 404904. Reported and
1116 tested by Sebastian Fontius
1118 2006-12-16 Miklos Szeredi <miklos@szeredi.hu>
1120 * kernel: don't keep unreferenced inodes in the icache.
1122 2006-12-15 Miklos Szeredi <miklos@szeredi.hu>
1124 * fusermount: Fix detection of fuseblk. Reported by Szakacsits
1127 * lib: Fix use after free in fuse_flush(). Reported by Ron
1130 2006-12-10 Miklos Szeredi <miklos@szeredi.hu>
1132 * mount.fuse: add "setuid=USER" option which does a "su - USER"
1135 * fusermount: use "/bin/mount -f" to add entry to /etc/mtab, and
1136 "/bin/umount" to remove entry from /etc/mtab. This gets rid of
1137 the ugly code dealing with mtab, as well as a possible race
1138 between fusermount and mount trying to modify /etc/mtab at the
1141 * Fix "buffer size too small: 4" warning for users of the
1142 fuse_loop_mt_proc() function.
1144 2006-12-04 Miklos Szeredi <miklos@szeredi.hu>
1146 * Fix warnings with gcc-4.1 on 64bit archs. Report from

1151 * Really fix fuse_teardown problem
1153 2006-12-02 Miklos Szeredi <miklos@szeredi.hu>
1155 * Add -lrt to fuse.pc (if needed) to fix static linking against
1156 libfuse. Reported by Szakacsits Szabolcs
1158 2006-12-01 Miklos Szeredi <miklos@szeredi.hu>
1162 2006-11-30 Miklos Szeredi <miklos@szeredi.hu>
1164 * Fix API version 21 and 22 compatibility for fuse_teardown.
1167 2006-11-29 Miklos Szeredi <miklos@szeredi.hu>
1169 * fusermount: Print a more helpful message in case the kernel
1170 doesn't support the 'fuseblk' filesystem type. This has been
1171 biting ntfs-3g users. Reported by Yura Pakhuchiy
1173 * kernel: fix build problem for "make -C ...". Reported by
1176 2006-11-19 Miklos Szeredi <miklos@szeredi.hu>
1178 * Fix bug in certain error paths of lookup routines. The request
1179 object was reused for sending FORGET, which is illegal. This bug
1180 could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
1181 silently corrupt memory in earlier versions. Report and test
1184 2006-11-11 Miklos Szeredi <miklos@szeredi.hu>
1186 * Print an error if an incompatible kernel interface version is
1187 detected in INIT. This will only show if filesystem is started
1190 * Fix order of fuse_destroy()/fuse_unmount() in error cleanup of
1191 fuse_setup_common(). Reported by Szakacsits Szabolcs
1193 2006-11-06 Miklos Szeredi <miklos@szeredi.hu>
1195 * Fix recursive locking in fuse_create(). Thanks to Takuya
1196 Ishibashi for the bug report
1198 2006-10-28 Miklos Szeredi <miklos@szeredi.hu>
1200 * Fix automake problem. Patch from Nix
1202 2006-10-26 Miklos Szeredi <miklos@szeredi.hu>
1204 * Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not
1205 always available on embedded systems. Patch from Paul Smith
1207 * Fix util/Makefile.am, so that failure to run update-rc.d or
1208 device creation doesn't cause make to fail. Reported by Paul
1211 2006-10-21 Miklos Szeredi <miklos@szeredi.hu>
1215 2006-10-18 Miklos Szeredi <miklos@szeredi.hu>
1217 * fusermount: don't try to create a lock file if /etc/mtab is a
1218 symlink. Report and patch from Alexei Sheplyakov (debian bug
1221 2006-10-17 Miklos Szeredi <miklos@szeredi.hu>
1223 * Minor changes, sync with mainline tree
1225 2006-10-16 Miklos Szeredi <miklos@szeredi.hu>
1227 * Released 2.6.0-rc3
1229 2006-10-15 Miklos Szeredi <miklos@szeredi.hu>
1233 2006-10-13 Miklos Szeredi <miklos@szeredi.hu>
1235 * kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
1236 Report from David Shaw
1238 * lib: Fix lost error on renaming a file. Report from David Shaw
1240 * lib: Fix lost error on hiding open files (renaming to
1243 * kernel: Fix a rare hang on SMP/32bit on heavy filesystem
1244 activity. The cause of the bug was that some calls to
1245 i_size_write() were not protected by a lock, and hence
1246 i_size_seqcount could become corrupted. This caused subsequent
1247 calls to i_size_read() to spin forever. This is a long standing
1248 bug was probably introduced in version 2.2, and thought to be
1249 related to NFS exporting (it's not). It was reported by various
1250 people, but Dana Henriksen has finally helped me to track it down,
1251 so big thanks to him
1253 * kernel: Protect against truncation of a swapfile
1255 2006-10-10 Miklos Szeredi <miklos@szeredi.hu>
1257 * kernel: Check for signature of super_operations->umount_begin().
1258 Ubuntu kernel 2.6.17 seems to use the new signature found in
1259 2.6.18. Thanks to Florent Mertens for the report
1261 2006-10-08 Miklos Szeredi <miklos@szeredi.hu>
1263 * Make sure inode numers wrap around at 2^32. This is needed on
1264 dual 64bit/32bit architectures, because 32bit applications using
1265 the non-largefile interface would otherwise break (EOVERFLOW error
1266 would be returned by the stat() system call family)
1268 * ulockmgr: handle the case, when a locking operation fails
1269 because no more file desctriptors are available in
1270 ulockmgr_server. Also work around a Linux kernel bug (known to
1271 exist for all Linux kernel versions <= 2.6.18) which may cause
1272 sent file descriptors to be lost in the above case
1274 * ulockmgr: optimize file descriptor use
1276 * restore needed cpp flags to util/Makefile.am
1278 * Install udev rules as 99-fuse.rules instead of 60-fuse.rules
1280 * Minor clean up of udev rules
1282 * Add a synchronous DESTROY message to kernel interface. This is
1283 invoked from umount, when the final instance of the filesystem is
1284 released. It is only sent for filesystems mounted with the
1285 'blkdev' option for security reasons.
1287 * If the DESTROY message is received, call the filesystem's
1288 ->destroy() method. In this case it's not called from session
1289 destruction as it would be otherwise.
1291 2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
1293 * Released 2.6.0-rc2
1295 2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
1297 * Add support for FLUSH+RELEASE operation for FreeBSD. Original
1300 * Add init script to insert fuse module and mount the control
1301 filesystem. The script is installed as /etc/init.d/fuse and on
1302 debian based systems (where update-rc.d is available) symlinks
1303 from /etc/rc*.d/ are also installed.
1305 * Include '#define FUSE_USE_VERSION=XX' into examples so they
1306 become more self contained.
1308 2006-09-30 Miklos Szeredi <miklos@szeredi.hu>
1312 * Move lock_owner from a separate argument into fuse_file_info
1314 * Add a flag to fuse_file_info indicating (1) a highlevel lock
1315 operation (unlock all) was initiated by a flush, (2) a lowlevel
1316 release operation should perform a flush as well.
1318 * fusermount: revert modprobe change (2006-08-18) since it
1319 doesn't work reliably with udev
1321 * Add support for block device backed filesystems. This mode is
1322 selected with the 'blkdev' option, which is privileged.
1324 * Add support for the bmap (FIBMAP ioctl) operation on block
1325 device backed filesystems. This allows swapon and lilo to work on
1330 * Drop support for kernels earlier than 2.6.9. Kernel module from
1331 previous (2.5.x) release can be used with library from this
1334 * In fuse_dentry_revalidate() use dget_parent() instead of
1335 dereferencing d_parent, since there's no protection against parent
1336 changing and going away
1338 * Protect nlookup from concurrent updates
1340 * In lookup if a directory alias exists but is unused,
1341 then get rid of it, otherwise return -EBUSY.
1343 * In mkdir if a directory alias exists, return success, but leave
1344 dentry negative. In reality this could happen if a remote rename
1345 immediately followed the mkdir.
1347 * Don't BUG in fuse_iget() if multiple retries are needed to get a
1348 good inode. This could happen if several lookups are racing for
1351 2006-09-29 Miklos Szeredi <miklos@szeredi.hu>
1353 * Fix compilation on 2.6.9. Report from Troy Ayers
1355 2006-09-27 Miklos Szeredi <miklos@szeredi.hu>
1357 * Fix Oops in fuse_readpages(). Reported by David Shaw
1359 2006-09-24 Csaba Henk <csaba.henk@creo.hu>
1361 * Add support for nanosec times on FreeBSD
1363 * Fix FreeBSD compatibility issues
1365 2006-09-23 Miklos Szeredi <miklos@szeredi.hu>
1367 * Fix one more compatibility bug. Thanks to Ricardo Correia
1369 * Fix utimens compilation with uClibc. Patch from Jamie Guinan
1371 2006-09-22 Miklos Szeredi <miklos@szeredi.hu>
1373 * Fixed several compatibility bugs in low level interface.
1374 Reported by Ricardo Correia
1376 * Add workaround for ARM caching bug
1378 2006-09-16 Miklos Szeredi <miklos@szeredi.hu>
1380 * Rename new utimes() method to more logical utimens()
1382 2006-09-14 Miklos Szeredi <miklos@szeredi.hu>
1384 * Fuse tried to unlink already unlinked hidden files. Bug
1385 reported by Milan Svoboda
1387 2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
1389 * Released 2.6.0-rc1
1391 2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
1393 * kernel: Fix unlock on close for kernels < 2.6.18
1395 * Add ulockmgr library & server. This can be used for handling
1396 file locking requests either directly from libfuse or over a
1397 network, etc. This first version is not optimized and the number
1398 of file descriptors it uses may get out of hand
1400 2006-09-07 Miklos Szeredi <miklos@szeredi.hu>
1402 * lib: Add interrupt support to high level library, which may be
1403 enabled with the 'intr' mount option.
1405 * When an operation is interrupted the thread handling that
1406 operation will receive SIGUSR1 (or other signal specified with the
1407 'intr_signal=N' option). The library installs a no-op signal
1408 handler for this signal, unless there's already a handler
1411 * The filesystem may query interrupt status (regardless of 'intr')
1412 with the fuse_interrupted() function.
1414 * mount.fuse: initialize $HOME if not set. Report from Sven Goldt
1416 2006-09-03 Miklos Szeredi <miklos@szeredi.hu>
1418 * lib: Multithreaded loop now allows unlimited number of threads.
1419 This is needed for locking operations which may block
1420 indefinitely. Also the kernel now doesn't limit the number of
1421 outstanding requests so the library shouldn't do so either.
1423 2006-09-01 Miklos Szeredi <miklos@szeredi.hu>
1425 * Fix recursive lock bug in interrupt handling
1427 * Add utimes() method to highlevel interface, which supports
1428 setting times with nanosecond resolution
1430 2006-08-18 Miklos Szeredi <miklos@szeredi.hu>
1432 * kernel: fix page leak if fuse_readpages() failed in it's
1433 initialization. Bug found and original patch from Alexander
1436 * For linux kernels >=2.6.18 (2.6.19 if using the fuse module from
1437 the kernel tree) the statfs method will receive the path within
1438 the filesystem on which the stat(v)fs syscall was called
1440 * fusermount: try to modprobe fuse module if invoked by root and
1441 unable to open device. This is needed with udev, since the device
1442 node will be created only when the module is inserted, hence
1443 module autoloading won't work. Reported by Szakacsits Szabolcs
1445 2006-07-30 Miklos Szeredi <miklos@szeredi.hu>
1447 * fusermount: if selinux is active, restore the original file's
1448 security context in unmount_rename(). Redhat bugzilla id 188561.
1449 Patch from Yves Perrenoud
1451 * Add POSIX file locking operation to high level library
1453 * Initialize context for unlink of hidden files on umount. Bug
1454 reported by Tim Stoakes
1456 2006-07-14 Miklos Szeredi <miklos@szeredi.hu>
1458 * Multiple release() calls can race with each other, resulting in
1459 the hidden file being deleted before the last release finishes.
1460 Bug found and patch tested by Mark Huijgen
1462 2006-07-05 Miklos Szeredi <miklos@szeredi.hu>
1464 * fusermount: if /dev/fuse doesn't exist, suggest modprobing fuse;
1465 this makes sense on systems using udev. Reported by Szakacsits
1468 2006-06-29 Miklos Szeredi <miklos@szeredi.hu>
1470 * Released 2.6.0-pre3
1472 2006-06-29 Miklos Szeredi <miklos@szeredi.hu>
1474 * Support in kernel module for file locking and interruption. The
1475 same functionality is available in official kernels >= 2.6.18
1477 2006-06-28 Miklos Szeredi <miklos@szeredi.hu>
1479 * Add POSIX file locking support
1481 * Add request interruption
1483 2006-06-06 Miklos Szeredi <miklos@szeredi.hu>
1485 * Add missing pthread_rwlock_destroy(). Patch from Remy Blank
1487 2006-06-05 Remy Blank <remy.blank@pobox.com>
1489 * lib: canonicalize mount point in fuse_helper_opt_proc() so that
1490 unmounting succeeds even if mount point was relative.
1492 2006-06-04 Csaba Henk <csaba.henk@creo.hu>
1494 * lib: fix emergency umount in helper.c when malloc fails.
1495 (The way it was done would end up in a segfault.)
1497 2006-06-01 Csaba Henk <csaba.henk@creo.hu>
1499 * lib: adjust threading related compiler flags.
1500 Switch to "-pthread" from "-lpthread" as that's the preferred
1501 one on several platforms. Consulted with Terrence Cole and
1504 2006-05-08 Miklos Szeredi <miklos@szeredi.hu>
1506 * lib: search fusermount in installation directory (bindir) as
1509 2006-05-03 Miklos Szeredi <miklos@szeredi.hu>
1511 * lib: fix compilation if CLOCK_MONOTONIC is not defined.
1512 Reported by Christian Magnusson
1514 2006-04-23 Csaba Henk <csaba.henk@creo.hu>
1516 * lib: make FreeBSD mount routine recognize if kernel features
1517 backgrounded init and if it does, run the mount util in foreground
1518 (similarly to Linux)
1520 2006-04-21 Miklos Szeredi <miklos@szeredi.hu>
1522 * kernel: fix fput deadlock fix, the lockless solution could lead
1523 to "VFS: busy inodes after umount..."
1525 * kernel: fix race between checking and setting file->private_data
1526 for the device. Found by Al Viro
1528 2006-04-11 Miklos Szeredi <miklos@szeredi.hu>
1530 * kernel: remove request pool, instead allocate requests on
1531 demand. Account the number of background requests, and if they go
1532 over a limit, block the allocation of new requests.
1534 * kernel: fix deadlock if backgrounded request holds the last
1535 reference to the super block
1537 * kernel: don't use fuse_reset_request() during direct I/O
1539 2006-04-06 Csaba Henk <csaba.henk@creo.hu>
1541 * lib: Let FreeBSD mount option parsing routine recognize "no"
1542 prefixes for FUSE specific options as well
1544 2006-04-01 Miklos Szeredi <miklos@szeredi.hu>
1546 * lib: Add missing rwlock initialization. Patch by Ryan Bradetich
1548 2006-03-17 Miklos Szeredi <miklos@szeredi.hu>
1552 * fuse_main(), fuse_setup() and fuse_new() have an additionl
1555 * fuse_mount() returns a 'struct fuse_chan' pointer instead of a
1558 * fuse_unmount() receives a 'struct fuse_chan' pointer. It
1559 destroys the given channel
1561 * fuse_teardown() no longer has a file descriptor parameter
1563 * new exported functions: fuse_session_remove_chan(),
1564 fuse_get_session(), fuse_daemonize()
1566 * fuse_chan_recv() may now return a new channel which will be used
1569 2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
1571 * Released 2.6.0-pre2
1573 2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
1575 * Don't unmount if already unmounted. This fixes a problem seen
1576 in the following situation: Lazy unmount a busy filesystem; Mount
1577 a new one in top; When the first finally unmounts, the second also
1578 unmounts. Reported by Franco Broi
1580 2006-03-15 Miklos Szeredi <miklos@szeredi.hu>
1582 * lowlevel lib: use indirect function calls instead of a
1583 switch/case construct. Besides increased efficiency it helps
1584 maintainability & readability too. Patch from Florin Malita
1586 2006-03-13 Miklos Szeredi <miklos@szeredi.hu>
1588 * kernel: replace global spinlock with a per-connection spinlock
1590 2006-03-10 Miklos Szeredi <miklos@szeredi.hu>
1592 * Fix source compatibility breakage for fuse_unmount(). Report
1595 2006-03-02 Miklos Szeredi <miklos@szeredi.hu>
1597 * Fix O_ASYNC handling in fuse_dev_release(). From Jeff Dike
1599 2006-03-01 Miklos Szeredi <miklos@szeredi.hu>
1601 * Add O_ASYNC and O_NONBLOCK support to FUSE device. Patch by
1604 * Renamed fuse_chan_receive() to fuse_chan_recv() and changed
1605 interface to return -errno in case of error.
1607 2006-03-01 Csaba Henk <csaba.henk@creo.hu>
1609 * libfuse: pass device file descriptor to fuse_unmount(), rewrite
1610 FreeBSD implementation so that it uses libc (sysctl backed) instead
1611 of an embdedded script (kmem backed). Adjust the control flow of
1612 hello_ll so that device doesn't get closed before unmount attempt.
1614 2006-02-25 Miklos Szeredi <miklos@szeredi.hu>
1616 * Lowlevel lib: return all-zero statvfs data if filesystem doesn't
1617 implement method. This is needed on FreeBSD, and nicer on Linux
1618 too. Highlevel lib already did this. Reported by Csaba Henk
1620 * Fix negative entry handling. There was a bug, that negative
1621 lookups with timeouts (nodeid == 0) returned -EIO.
1623 2006-02-23 Miklos Szeredi <miklos@szeredi.hu>
1625 * Fix race between RELEASE and UNLINK, which might leave
1626 .fuse_hidden* files around
1628 2006-02-21 Miklos Szeredi <miklos@szeredi.hu>
1630 * fusexmp_fh: implement flush() method and call close() on the
1631 open file descriptor. This is needed if used on an NFS
1632 filesystem, which buffers data until file is closed. Franco Broi
1633 spotted the situation when 'cp -p' failed to set the modification
1634 time because of this.
1636 2006-02-20 Miklos Szeredi <miklos@szeredi.hu>
1638 * Released 2.6.0-pre1
1640 2006-02-19 Miklos Szeredi <miklos@szeredi.hu>
1642 * libfuse: fix use-after-free bug in interruptred reply_entry().
1643 Patch from John Muir
1645 * libfuse: fix wrong symbol versioning for fuse_mount. Debian bug
1646 ID: 352631. Found by Stéphane Rosi
1648 2006-02-17 Miklos Szeredi <miklos@szeredi.hu>
1650 * Lowlevel lib: Unify fuse_dirent_size() and fuse_add_dirent()
1651 into a single function fuse_add_direntry(). This cleans up the
1652 interface and makes it possible to do stacking.
1654 2006-02-16 Miklos Szeredi <miklos@szeredi.hu>
1656 * Fix rare race betweeen abort and release caused by failed iget()
1657 in fuse_create_open().
1659 * Add 'ac_attr_timeout' option e.g. for filesystems which do their
1660 own attribute caching.
1662 2006-02-15 Miklos Szeredi <miklos@szeredi.hu>
1664 * Work around FreeBSD runtime linker "feature" which binds an old
1665 version of a symbol to internal references if the symbol has more
1666 than one version. This resulted in infinite recursion in
1667 fuse_lowlevel_new_compat25().
1669 2006-02-10 Csaba Henk <csaba.henk@creo.hu>
1671 * Refine clock_gettime() querying so that linker options
1672 shall be set as it's appropriate for the target platform.
1674 2006-02-09 Miklos Szeredi <miklos@szeredi.hu>
1676 * Fix udev rule syntax. Reported by Nix
1678 2006-02-08 Miklos Szeredi <miklos@szeredi.hu>
1680 * In some cases udev rule seems to be ineffective when installed
1681 as 40-fuse.rules but work as 60-fuse.rules. Reported by John Hunt
1683 2006-02-03 Miklos Szeredi <miklos@szeredi.hu>
1685 * Fix compilation when build directory is different from source
1686 directory. Reported by Frédéric L. W. Meunier
1688 2006-02-02 Miklos Szeredi <miklos@szeredi.hu>
1690 * Fix even bigger bug introduced in fix for request_end() on
1691 2006-01-14. Reported by Gal Rosen
1693 2006-01-30 Miklos Szeredi <miklos@szeredi.hu>
1695 * highlevel-lib: add 'auto_cache' option. This caches file data
1696 based on modification time and size
1698 2006-01-20 Miklos Szeredi <miklos@szeredi.hu>
1700 * Sanitize storage type and help message in mount_bsd.c. Patch
1703 * fuse_opt: add new helper constants FUSE_OPT_KEY_KEEP and
1704 FUSE_OPT_KEY_DISCARD
1706 * Add options 'max_readahead', 'sync_read' and 'async_read'
1708 * Kernel ABI version 7.6:
1710 * Negotiate the 'max_readahead' value and 'async_read' flags with
1711 userspace in the INIT method
1713 * Add connection info to ->init() methods to both lowlevel and
1716 * Fall back to synchronous read() behavior if either library or
1717 userspace filesystem is using the old interface version. This is
1718 needed so non-updated filesystems won't be confused by the
1719 different read() behavior
1721 2006-01-19 Miklos Szeredi <miklos@szeredi.hu>
1723 * lib: if "fsname=" option was given, pass it to fusermount
1725 * fuse_opt: add new fuse_opt_insert_arg() function, which is
1726 needed by filesystems to implement some argument manipulations
1729 * fuse_opt: fix memory leak in handling "--" option
1731 2006-01-18 Miklos Szeredi <miklos@szeredi.hu>
1733 * kernel: fix detection of case when fuse is not configured into
1734 the kernel either as module or built-in
1736 * fuse_opt.h: fix incompatibility with C++ compilers by renaming
1737 'template' structure member to 'templ'. Reported by Takashi Iwai
1739 * fuse.h: fix compatibility bugs. Patch by Yura Pakhuchiy
1741 * kernel: support version 2.6.16 (i_sem -> i_mutex)
1743 2006-01-16 Miklos Szeredi <miklos@szeredi.hu>
1745 * Added (again) asynchronous readpages support
1747 * Each connection now shows up under /sys/fs/fuse/connections
1749 * Connection attributes exported to sysfs: 'waiting' number of
1750 waiting requests; 'abort' abort the connection
1752 * Connection may be aborted through either the sysfs interface or
1753 with 'umount -f mountpoint'
1755 2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
1759 2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
1761 * kernel: fix a couple of bugs
1763 * Order of request_end() and fuse_copy_finish() was wrong.
1764 Posthumous note: Franco Broi managed to exploit this, though it
1765 seemed quite impossible
1767 * request_end() used request pointer after decrementing refcount
1769 * Clearing ->connected or ->mounted connection flags could race
1770 with setting other bitfields not protected with a lock
1772 2006-01-10 Miklos Szeredi <miklos@szeredi.hu>
1774 * kernel: add necessary compile flags for 2.4.X/x86_64.
1775 Report from Sean Ziegeler
1777 2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
1779 * Released 2.5.0-pre2
1781 2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
1783 * Applied patch from Csaba Henk, to update mount_bsd to new
1784 fuse_mount() semantics
1786 * Ignore auto,noauto,... options in mount.fuse. Reported by Frank
1787 Steiner and Don Taber
1789 * fusermount: add 'dirsync' mount option
1791 2006-01-07 Miklos Szeredi <miklos@szeredi.hu>
1793 * Improved help reporting and added version reporting to library
1795 2006-01-06 Miklos Szeredi <miklos@szeredi.hu>
1797 * Change working directory to "/" even if running in the
1798 foreground. Patch from Jonathan Brandmeyer
1800 * Changed lots of functions to use 'struct fuse_args' instead of
1801 separate argc and argv
1803 * Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
1804 fuse_remove_signal_handlers() functions, so that it's now pretty
1805 easy to get all the functionality of fuse_main() with a filesystem
1806 using the lowlevel API.
1808 2006-01-02 Miklos Szeredi <miklos@szeredi.hu>
1810 * mount.fuse: the 'user' option should be ignored. Report and
1811 solution from Mattd.
1813 * mount.fuse: export PATH in the right place. Report and patch
1814 from Hannes Schweizer
1816 2005-12-16 Miklos Szeredi <miklos@szeredi.hu>
1818 * Clean up the option parsing interface slightly, by creating an
1819 "argument list" structure, that contains the argument vector and
1822 2005-12-15 Miklos Szeredi <miklos@szeredi.hu>
1824 * fusermount: check if /mnt/mtab is a symlink and don't modify it
1827 * kernel: simplify request size limiting. INIT only contains
1828 maximum write size, maximum path component size remains fixed at
1829 1024 bytes, and maximum xattr size depends on read buffer.
1831 2005-12-14 Miklos Szeredi <miklos@szeredi.hu>
1833 * Fix readdir() failure on x86_64, of 32bit programs compiled
1834 without largefile support. Bug report and help from Anthony
1837 * If lookup returns invalid mode, return -EIO instead of creating
1840 * Add current output argument vector to option processing
1843 2005-12-12 Miklos Szeredi <miklos@szeredi.hu>
1845 * Fix stale code in ifdef FreeBSD. Patch from Csaba Henk
1847 2005-12-09 Miklos Szeredi <miklos@szeredi.hu>
1849 * Released 2.5.0-pre1
1851 2005-12-09 Miklos Szeredi <miklos@szeredi.hu>
1853 * libfuse: added option parsing interface, defined in
1856 2005-12-07 Miklos Szeredi <miklos@szeredi.hu>
1858 * Return EIO for file operations (read, write, fsync, flush) on
1859 open files whose inode has become "bad". Inodes will be marked
1860 "bad" if their type changes. Bug report by Csaba Henk
1862 2005-12-06 Miklos Szeredi <miklos@szeredi.hu>
1864 * Use bigger request buffer size. write() did not work on archs
1865 with > 4k page size, Bug report by Mark Haney
1869 * Extend INIT reply with data size limits
1871 2005-12-02 Miklos Szeredi <miklos@szeredi.hu>
1873 * Fix memory leak in fuse_read_cmd()/fuse_process_cmd(). Bug
1874 reported by Vincenzo Ciancia
1876 * Handle exit-by-umount in fuse_read_cmd()
1878 2005-11-29 Miklos Szeredi <miklos@szeredi.hu>
1880 * Check if '-msoft-float' option is supported by compiler when
1881 configuring for a 2.4.x kernel. Bug report by Mark Haney
1883 * In multithreaded loop send a TERM signal to the main thread if
1884 one of the other threads exit. Needed on FreeBSD for a clean exit
1885 on umount. Should not cause any harm on Linux either
1887 2005-11-28 Miklos Szeredi <miklos@szeredi.hu>
1889 * Fix bug in 32-bit file handle compatibility
1891 2005-11-27 Miklos Szeredi <miklos@szeredi.hu>
1893 * Block TERM, INT, HUP and QUIT signals in all but the main
1894 thread. According to POSIX it's not specified which thread will
1895 receive these signals.
1899 * Check for directory aliasing on mkdir, not just on lookup
1901 * Check for special node ID values in create+open operation
1903 * Sync with -mm: readv, writev, aio_read and aio_write methods
1904 added to file operations
1906 * Cleanups: lookup code, page offset calculation
1908 * ABI stepped to 7.4, changes:
1910 * frsize member added to fuse_kstatfs structure
1912 * added support for negative entry caching: on lowlevel API if
1913 fuse_entry_param::ino is set to zero in reply to a lookup request,
1914 the kernel will cache the dentry for the specified amount of time.
1916 * libfuse: added 'negative_timeout' option: specifies how much
1917 negative entries should be cached. Default is zero, to be
1918 compatible with prior versions
1920 2005-11-22 Miklos Szeredi <miklos@szeredi.hu>
1922 * Add detection of mainline FUSE code in running kernel
1924 2005-11-21 Miklos Szeredi <miklos@szeredi.hu>
1926 * Don't use async cancelation in multithreaded loop. This makes
1927 it more portable to systems where read() is not async cancel safe.
1928 Report from Andriy Gapon
1930 2005-11-20 Miklos Szeredi <miklos@szeredi.hu>
1932 * Warn if API version 11 compatibility is requested
1934 2005-11-17 Miklos Szeredi <miklos@szeredi.hu>
1936 * More FreeBSD merge
1938 * fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
1939 them, because it corrupts /etc/mtab. Found by Thomas Biege
1942 * libfuse: don't use system() to invoke 'fusermount -u ...'
1943 because it breaks mountpoints with spaces in them into multiple
1946 2005-11-16 Miklos Szeredi <miklos@szeredi.hu>
1948 * Merge library part of FreeBSD port. Patch by Csaba Henk
1950 2005-11-11 Miklos Szeredi <miklos@szeredi.hu>
1952 * Use 64bit type for file handle, so the full range supported by
1953 the kernel interface is available to applications
1955 2005-11-10 Miklos Szeredi <miklos@szeredi.hu>
1957 * Moved mountpoint argument checking from fuse_parse_cmdline() to
1958 fuse_mount() in preparation to FreeBSD merge.
1960 2005-11-08 Miklos Szeredi <miklos@szeredi.hu>
1962 * Remove unneeded close() from fuse_teardown(). Spotted by Csaba
1965 2005-11-07 Miklos Szeredi <miklos@szeredi.hu>
1967 * Make the statfs change backwards compatible.
1969 2005-11-06 Miklos Szeredi <miklos@szeredi.hu>
1971 * Change ->statfs() method to use 'struct statvfs' instead of
1972 'struct statfs'. This makes the API more portable since statvfs()
1973 is defined by POSIX.
1975 2005-10-28 Miklos Szeredi <miklos@szeredi.hu>
1977 * Add fgetattr() method, which currently will only be called after
1978 a successful call to a create() method.
1980 2005-10-26 Miklos Szeredi <miklos@szeredi.hu>
1982 * Change kernel ABI version to 7.3
1984 * Add ACCESS operation. This is called from the access() system
1985 call if 'default_permissions' mount option is not given, and is
1986 not called on kernels 2.4.*
1988 * Add atomic CREATE+OPEN operation. This will only work with
1989 2.6.15 (presumably) or later Linux kernels.
1991 * Add ftruncate() method. This will only work with 2.6.15
1992 (presumably) or later Linux kernels.
1994 * Fix kernel module compile if kernel source and build directories
1995 differ. Report and initial patch by John Eastman
1997 2005-10-18 Miklos Szeredi <miklos@szeredi.hu>
1999 * lib: optimize buffer reallocation in fill_dir.
2001 2005-10-17 Miklos Szeredi <miklos@szeredi.hu>
2005 2005-10-14 Miklos Szeredi <miklos@szeredi.hu>
2007 * libfuse: add debug for write result (by Shaun Jackman) and
2008 warnings for too large read/write result
2010 2005-10-11 Miklos Szeredi <miklos@szeredi.hu>
2012 * Spelling fixes, thanks to Ioannis Barkas
2014 2005-10-10 Miklos Szeredi <miklos@szeredi.hu>
2016 * fuse_common.h: use extern "C". Thanks to Valient Gough for the
2019 2005-10-07 Miklos Szeredi <miklos@szeredi.hu>
2021 * highlevel-lib: init() and destroy() methods didn't have an
2022 initialized fuse_context. Bug reported by Tim Stoakes
2024 2005-10-04 Miklos Szeredi <miklos@szeredi.hu>
2028 2005-10-03 Miklos Szeredi <miklos@szeredi.hu>
2030 * Add documentation to fuse_lowlevel.h
2034 * Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME
2036 * Move fuse_mount() and fuse_unmount() to fuse_common.h
2038 * Change the return type of fuse_reply_none() from int to void.
2040 2005-09-30 Miklos Szeredi <miklos@szeredi.hu>
2042 * kernel: NFS exporting leaked dentries. Bug found and fixed by
2045 2005-09-29 Miklos Szeredi <miklos@szeredi.hu>
2047 * fusermount: fix error message, when unable to open /dev/fuse.
2048 Report by Balázs Pozsár
2050 2005-09-28 Miklos Szeredi <miklos@szeredi.hu>
2052 * UClibc fixes from Christian Magnusson
2054 2005-09-27 Miklos Szeredi <miklos@szeredi.hu>
2056 * Added NAME="%k" to util/udev.rules. Fix by Mattias Wadman.
2058 2005-09-26 Miklos Szeredi <miklos@szeredi.hu>
2060 * Released 2.4.0-rc1
2062 2005-09-26 Miklos Szeredi <miklos@szeredi.hu>
2064 * fusermount: allow user umount in the case when /etc/mtab is a
2065 symlink to /proc/mounts. Reported by Balázs Pozsár.
2067 2005-09-23 Miklos Szeredi <miklos@szeredi.hu>
2069 * Check for special node ID values in lookup and creation
2071 2005-09-22 Miklos Szeredi <miklos@szeredi.hu>
2073 * Slight optimization in returning EINVAL error in case of an open
2076 2005-09-20 Miklos Szeredi <miklos@szeredi.hu>
2078 * Remove '--enable-auto-modprobe' configure flag. Module
2079 auto-loading is now handled by the kernel.
2081 2005-09-15 Miklos Szeredi <miklos@szeredi.hu>
2083 * Install UDEV rule file, so /dev/fuse is created with mode 0666.
2084 Help from Jens M. Noedler.
2086 2005-09-14 Miklos Szeredi <miklos@szeredi.hu>
2088 * Add memory cleanup on thread exit
2090 2005-09-13 Miklos Szeredi <miklos@szeredi.hu>
2092 * Set umask to zero in fusexmp and fusexmp_fh, so that
2093 files/directories are created with the requested mode.
2095 2005-09-12 Miklos Szeredi <miklos@szeredi.hu>
2097 * Don't ignore read error in multithreaded loop
2099 2005-09-08 Miklos Szeredi <miklos@szeredi.hu>
2101 * Released 2.4.0-pre2
2103 2005-09-08 Miklos Szeredi <miklos@szeredi.hu>
2105 * Revert lock and access operations. Postpone these until 2.5.
2107 2005-09-02 Miklos Szeredi <miklos@szeredi.hu>
2109 * Fix compile warning on 2.6.13 and later
2111 * Fix compilation on old kernels
2113 2005-08-19 Miklos Szeredi <miklos@szeredi.hu>
2115 * lib: always refresh directory contents after rewinddir() to
2116 conform to SUS. Bug found by John Muir.
2118 2005-08-15 Miklos Szeredi <miklos@szeredi.hu>
2120 * Released 2.4.0-pre1
2122 2005-08-14 Miklos Szeredi <miklos@szeredi.hu>
2124 * lib: cleaned up (or messed up, depending on your POV) the low
2125 level library API. Hopefully this is close to the final form.
2127 2005-08-05 Miklos Szeredi <miklos@szeredi.hu>
2129 * fusermount: don't allow empty mountpoint argument, which defeats
2130 automatic umounting in fuse_main(). Bugreport by Václav Jůza
2132 2005-08-03 Miklos Szeredi <miklos@szeredi.hu>
2134 * fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
2135 option is used (Paul Alfille).
2137 2005-08-02 Miklos Szeredi <miklos@szeredi.hu>
2139 * highlevel-lib: added mount options "attr_timeout" and
2140 "entry_timeout". These options control the length of time file
2141 attributes and entries (names) are cached. Both default to 1.0
2144 * kernel: correctly handle zero timeout for attributes and entries
2146 2005-08-01 Miklos Szeredi <miklos@szeredi.hu>
2148 * Added missing symbols to versionscript (Joshua J. Berry)
2150 * kernel: implement two flags, open can set: 'direct_io' and
2151 'keep_cache'. These correspond exactly to mount options
2152 'direct_io' and 'kernel_cache', but allow a per-open setting.
2154 * Move 'direct_io' and 'kernel_cache' mount option handling to
2155 userspace. For both mount options, if the option is given, then
2156 the respective open flag is set, otherwise the open flag is left
2157 unmodified (so the filesystem can set it).
2159 * lib (highlevel): make open method optional
2161 2005-07-28 Miklos Szeredi <miklos@szeredi.hu>
2163 * kernel: invalidate attributes for read/readdir/readlink
2166 * kernel: detect newer UML kernels
2168 2005-07-26 Miklos Szeredi <miklos@szeredi.hu>
2170 * Make the installation path of fuse.ko and mount.fuse
2171 configurable through INSTALL_MOD_PATH and MOUNT_FUSE_PATH
2172 environment variables. Requirement and help from Csaba Henk.
2174 2005-07-22 Miklos Szeredi <miklos@szeredi.hu>
2176 * Fix bug, that causes filesystem requests to hang when unique
2177 request counter becomes negative. This happens after
2178 2,147,483,648 operations, so most people won't care. Thanks to
2179 Franco Broi for the report and testing.
2181 2005-07-21 Miklos Szeredi <miklos@szeredi.hu>
2183 * Don't change mtime/ctime/atime to local time on read/write.
2184 Bug reported by Ben Grimm
2186 * Install fuse_common.h and fuse_lowlevel.h. Report by Christian
2189 * fusermount: use getopt_long() for option parsing. It allows the
2190 use of '--' to stop argument scanning, so fusermount can now
2191 operate on directories whose names begin with a '-'. Patch by
2194 2005-07-15 Miklos Szeredi <miklos@szeredi.hu>
2196 * fusermount: add '-v', '--version' and '--help' options
2198 * add inode based API
2200 2005-07-12 Miklos Szeredi <miklos@szeredi.hu>
2202 * lib: don't block signals in worker threads. Problem noticed by
2205 2005-07-07 Miklos Szeredi <miklos@szeredi.hu>
2207 * lib: don't allow both 'allow_other' and 'allow_root' options to
2210 2005-07-06 Miklos Szeredi <miklos@szeredi.hu>
2212 * fusermount: check if mountpoint is empty (only '.' and '..' for
2213 directories, and size = 0 for regular files). If "nonempty"
2214 option is given, omit this check. This is useful, so users don't
2215 accidentally hide data (e.g. from backup programs). Thanks to
2216 Frank van Maarseveen for pointing this out.
2218 * kernel: check if mandatory mount options ('fd', 'rootmode',
2219 'user_id', 'group_id') are all given
2221 * lib: simplify 'readdir_ino' handling
2223 * lib: add mount options 'umask=M', 'uid=N', 'gid=N'
2225 2005-07-03 Miklos Szeredi <miklos@szeredi.hu>
2227 * kernel: clean up 'direct_io' code
2229 2005-06-28 Miklos Szeredi <miklos@szeredi.hu>
2231 * Add 'mount.fuse' written by Petr Klima
2233 * '/dev/fuse' is created by 'make install' if does not yet exist
2235 2005-06-20 Miklos Szeredi <miklos@szeredi.hu>
2237 * Fix UCLIBC compile error. Patch by Christian Magnusson
2239 2005-06-08 Miklos Szeredi <miklos@szeredi.hu>
2241 * Enable the auto-loading of the module via access to the
2242 corresponding device file. Patch by Takashi Iwai.
2244 * Allow mounting a regular file (over a regular file) for
2247 * Do not create temporary device file. Require "/dev/fuse" to
2248 exist, and be readable/writable by the mounting user.
2250 2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
2254 2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
2256 * Fix serious information leak: if the filesystem returns a short
2257 byte count to a read request, and there are non-zero number of
2258 pages which are not filled at all, these pages will not be zeroed.
2259 Hence the user can read out previous memory contents. Found by
2262 2005-05-27 Miklos Szeredi <miklos@szeredi.hu>
2264 * Add "readdir_ino" mount option, which tries to fill in the d_ino
2265 field in struct dirent. This mount option is ignored if "use_ino"
2266 is used. It helps some programs (e.g. 'pwd' used over NFS from a
2267 non-Linux OS). Patch by David Shaw.
2269 2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
2273 2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
2275 * File save in krusader and other editors doesn't work with sshfs,
2276 because open() is interrupted by a periodic signal, and open()
2277 restarts forever, without any progress. This could just be fixed
2278 in open(), but the problem is more generic: if signals are
2279 received more often than the filesystem can get the request to
2280 userspace, it will never finish. This is probably only a
2281 theoretical problem, nevertheless I'm removing the possibility to
2282 interrupt requests with anything other than SIGKILL, even before
2283 being sent to userspace. Bugreport by Eduard Czimbalmos.
2285 2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
2287 * libfuse: add "tree_lock" rwlock, that is locked for write in
2288 rename, unlink and rmdir, and locked for read in all other
2289 operations. This should fix the rename/release race reported by
2290 Valient Gough and others. The solution is very coarse, a finer
2291 grained locking scheme could be implemented, but it would be much
2292 more complex. Let's see whether this is good enough.
2294 2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
2298 2005-05-08 Miklos Szeredi <miklos@szeredi.hu>
2300 * Better fix for out of order FORGET messages. Now the
2301 LOOKUP/FORGET messages are balanced exactly (one FORGET can
2302 balance many lookups), so the order no longer matters. This
2303 changes the kernel ABI slightly, but the library remains backward
2306 2005-05-06 Miklos Szeredi <miklos@szeredi.hu>
2308 * Fix abort for out of order FORGET messages. Again. Spotted by
2309 Franco Broi again. Sorry :)
2311 2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
2315 2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
2317 * Make fusermount work with fuse kernel modules not yet supporting
2318 the "group_id" option (added for the purpose of stricter
2319 permission checking).
2321 2005-04-28 Miklos Szeredi <miklos@szeredi.hu>
2323 * Check for hard-linked directories in lookup. This could cause
2324 problems in the VFS, which assumes that such objects never exist.
2326 * Make checking of permission for other users more strict. Now
2327 the same privilege is required for the mount owner as for ptrace
2328 on the process performing the filesystem operation.
2330 2005-04-23 Miklos Szeredi <miklos@szeredi.hu>
2334 2005-04-22 Miklos Szeredi <miklos@szeredi.hu>
2336 * Add -msoft-float to kernel module compile flags for 2.4.X. This
2337 is needed on certain architectures. Report from Chris Kirby
2339 * Fix buggy behavior of open(..., O_CREAT|O_EXCL) if interrupted.
2340 Reported by David Shaw
2342 * Remove "allow_root" option from kernel module, and implement
2343 it's functionality in the library
2345 * Fix Oops caused by premature release of fuse_conn. Clean up
2346 related code, to be more readable
2348 * Sendfile should not use page cache if "direct_io" mount option
2351 2005-04-08 Miklos Szeredi <miklos@szeredi.hu>
2353 * Fix Oops in case of nfs export. Spotted by David Shaw
2355 * Fix another Oops in case of write over nfs with direct_io turned
2356 on. Again spotted by David Shaw
2358 2005-04-07 Miklos Szeredi <miklos@szeredi.hu>
2362 2005-04-07 Miklos Szeredi <miklos@szeredi.hu>
2364 * lib: finalized new readdir() interface, which now supersedes the
2367 2005-04-03 Miklos Szeredi <miklos@szeredi.hu>
2371 2005-04-03 Miklos Szeredi <miklos@szeredi.hu>
2373 * Implement backward compatibility with version 5 kernel ABI
2375 2005-04-01 Miklos Szeredi <miklos@szeredi.hu>
2379 2005-04-01 Miklos Szeredi <miklos@szeredi.hu>
2381 * kernel: fix dirent offset handling
2383 * lib: add readdir and releasedir methods
2385 * lib: use fh field of fuse_file_info in opendir, readdir,
2386 releasedir and fsyncdir methods
2388 * lib: check kernel API version and bail out of it's old. This
2389 will be properly fixed in the next release
2391 2005-03-31 Miklos Szeredi <miklos@szeredi.hu>
2395 2005-03-31 Miklos Szeredi <miklos@szeredi.hu>
2397 * kernel API: add padding to structures, so 64bit and 32bit
2398 compiler will return the same size
2400 * kernel API: add offset field to fuse_dirent. This will allow
2401 more sophisticated readdir interface for userspace
2403 * kernel API: change major number to 6
2405 * kernel: fix warnings on 64bit archs
2407 * kernel: in case of API version mismatch, return ECONNREFUSED
2409 2005-03-24 Miklos Szeredi <miklos@szeredi.hu>
2411 * kernel: trivial cleanups
2413 2005-03-21 Miklos Szeredi <miklos@szeredi.hu>
2415 * Add fsyncdir() operation
2417 2005-03-19 Miklos Szeredi <miklos@szeredi.hu>
2419 * kernel: add locking to background list (fixes previous fix)
2421 2005-03-18 Miklos Szeredi <miklos@szeredi.hu>
2423 * kernel: fix bug which could cause leave busy inodes after
2426 2005-03-08 Miklos Szeredi <miklos@szeredi.hu>
2428 * examples: add -lpthread to link flags to work around valgrind
2431 * lib: don't exit threads, so cancelation doesn't cause segfault
2433 2005-03-04 Miklos Szeredi <miklos@szeredi.hu>
2435 * kernel: fix nasty bug which could cause an Oops under certain
2436 situations. Found by Magnus Johansson
2438 2005-02-28 Miklos Szeredi <miklos@szeredi.hu>
2440 * libfuse: added opendir() method. This can be used in case
2441 permission checking in getdir() is too late. Thanks to Usarin
2442 Heininga for pointing out this deficiency
2444 * libfuse: added init() and destroy() methods to fuse_operations
2446 * kernel: llseek() method for files and directories made explicit
2448 * kernel: fixed inode leak in NFS export in case of nodeid
2451 2005-02-15 Miklos Szeredi <miklos@szeredi.hu>
2453 * libfuse: clean up some unitialized memory found with valgrind
2455 * Add -lpthread to Libs in fuse.pc. Valgrind seems to need an
2456 explicitly linked libpthread for applications
2458 2005-02-10 Miklos Szeredi <miklos@szeredi.hu>
2460 * fusermount: set umask, otherwise /etc/mtab will have
2461 unpredictable permission. Spotted by Jindrich Kolorenc
2463 * fusermount: set owner and group of /etc/mtab to original values
2466 * libfuse: add 'use_ino' option to help. Patch by Valient Gough
2468 2005-02-07 Miklos Szeredi <miklos@szeredi.hu>
2470 * Cleaned up directory reading (temporary file is not used)
2472 2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
2476 2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
2478 * Fix possible race when operation is interrupted
2480 2005-01-28 Miklos Szeredi <miklos@szeredi.hu>
2482 * Fix compilation on 2.6.7
2484 2005-01-26 Miklos Szeredi <miklos@szeredi.hu>
2488 2005-01-26 Miklos Szeredi <miklos@szeredi.hu>
2490 * Fix bug in link() operation which caused the wrong path to be
2491 passed as the first argument. Found by Anton Altaparmakov
2493 2005-01-21 Miklos Szeredi <miklos@szeredi.hu>
2495 * LIB: fix double reply in readdir operation
2497 * fusermount: fix uid checking bug. Patch by Adam Connell
2499 * KERNEL: fix compile on various RedHat patched 2.4 kernels.
2500 Patch by Keshava Gowda
2502 2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
2504 * KERNEL: provide correct llseek semantics for fuse device (fixes
2505 a bug on Progeny 2.4.20 kernel). Reported by Valient Gough
2507 2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
2509 * Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)
2511 2005-01-18 Miklos Szeredi <miklos@szeredi.hu>
2513 * KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
2514 and RELEASEDIR. This ends the ugly hack of passing a file
2515 descriptor to the kernel, and actually makes the code simpler.
2517 2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
2521 2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
2523 * fusermount: remove capability setting, which was the cause of
2524 problems for some users. It seems that FS related capabilities
2525 are removed by setfsuid(), so this isn't even needed.
2527 2005-01-15 Miklos Szeredi <miklos@szeredi.hu>
2529 * fix compilation on 2.4 kernels (reported by Valient Gough)
2531 * fix failure to unmount bug (found by David Shaw)
2533 * fusermount: improve parsing of /etc/fuse.conf
2535 2005-01-13 Miklos Szeredi <miklos@szeredi.hu>
2537 * Remove 'mount_max' and 'user_allow_other' module options. These
2538 are now checked by fusermount, and can be set in /etc/fuse.conf
2540 * KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)
2542 2005-01-11 Miklos Szeredi <miklos@szeredi.hu>
2544 * KERNEL: fix possible inode allocation problem, where
2545 sizeof(struct inode) is not aligned (found by Mike Waychison)
2547 * KERNEL: use new follow_link/put_link methods
2549 * KERNEL: cosmetic fixes
2551 2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
2555 2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
2557 * Add missing code that was accidently left out
2559 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2563 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2565 * Change "uid" mount option to "user_id" to avoid confusion with a
2566 mount option "uid" commonly used by many filesystems
2568 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2572 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2574 * If FUSE is configured in the kernel, don't build it by default
2576 2005-01-07 Miklos Szeredi <miklos@szeredi.hu>
2578 * Compile fix by Christian Magnusson
2580 2005-01-05 Miklos Szeredi <miklos@szeredi.hu>
2582 * Fix compilation for 2.6.{0-5} kernels
2584 2005-01-04 Miklos Szeredi <miklos@szeredi.hu>
2586 * KERNEL: if request is interrupted, still keep reference to used
2587 inode(s) and file, so that FORGET and RELEASE are not sent until
2588 userspace finishes the request.
2590 * remove /{sys,proc}/fs/fuse/version, and instead add an INIT
2591 request with the same information, which is more flexible,
2592 simpler, works on embedded systems.
2594 2004-12-16 Miklos Szeredi <miklos@szeredi.hu>
2596 * KERNEL ABI: update interface to make it independent of type
2597 sizes. This will help on 64 bit architectures which can run
2598 legacy 32 bit applications.
2600 * KERNEL ABI: add "len" field to request headers. This will allow
2601 sending/receiving requests in multiple chunks.
2603 * KERNEL: handle file type change more intelligently
2605 * LIB: "-o debug" option should disable backgrounding (fix by
2606 Fabien Reygrobellet)
2608 2004-12-13 Miklos Szeredi <miklos@szeredi.hu>
2610 * KERNEL: invalidate dentry/attributes if interrupted request
2611 could leave filesystem in an unknown state.
2613 2004-12-12 Miklos Szeredi <miklos@szeredi.hu>
2615 * KERNEL: lots of cleanups related to avoiding possible deadlocks.
2616 These will cause some regressions, but stability is considered
2617 more important. If any of these features turns out to be
2618 important, it can be readded with the deadlock problems addressed.
2620 * Make all requests interruptible (only with SIGKILL currently).
2621 This can be used to break any deadlock produced by the userspace
2622 filesystem accessing it's own exported files. The RELEASE request
2623 is special, because if it's interrupted before sending it to
2624 userspace it is still sent, but the reply is not awaited.
2626 * If request is interrupted before being sent to userspace, and if
2627 it hasn't yet got any side effects, it is always restarted,
2628 regardless of the SA_RESTART flag. This makes these interruptions
2629 transparent to the process.
2631 * Remove shared-writable mmap support, which was prone to an
2632 out-of-memory deadlock situation
2634 * Remove INVALIDATE userspace initiated request
2636 * Make readpages() synchronous. Asynchronous requests are
2637 deadlock prone, since they cannot be interrupted.
2639 * Add readv/writev support to fuse device operations
2641 * Remove some printks, which userspace FS can use for a DoS
2644 * Remove 'large_read' mount option from 2.6 in kernel, check it in
2647 * LIB: improve compatibility with a fuse.h header installed in
2648 ${prefix}/include which in turn includes the real header.
2650 * LIB: improve compatibility by defining fuse_main() (which is now
2651 not used), so old configure scripts find it.
2653 2004-12-10 Miklos Szeredi <miklos@szeredi.hu>
2655 * When mounting on a subdirectory of / don't duplicate slashes at
2656 the beggining of path (spotted by David Shaw)
2658 2004-12-09 Miklos Szeredi <miklos@szeredi.hu>
2660 * Fix bug causing garbage in mount options (spotted by David Shaw)
2662 2004-12-07 Miklos Szeredi <miklos@szeredi.hu>
2664 * Add 'writepage' flag to 'fuse_file_info'.
2666 * More comments in fuse.h
2668 * Get rid of double underscores
2670 2004-12-04 Miklos Szeredi <miklos@szeredi.hu>
2672 * Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config
2674 * helper.c: add -ho option, which only displays the options not
2675 the usage header. This can be used by filesystems which have
2678 2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
2680 * Add source compatibility to 2.1 and 1.1 APIs. To select betwen
2681 versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
2682 including the fuse header
2684 * Add binary compatibility to 2.1 version of library with symbol
2687 2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
2691 2004-12-01 Miklos Szeredi <miklos@szeredi.hu>
2693 * kernel: clean up writing functions
2695 * kernel: no allocation on write in direct_io mode
2697 * move linux/fuse.h to fuse_kernel.h
2699 2004-11-30 Miklos Szeredi <miklos@szeredi.hu>
2701 * kernel: clean up reading functions
2703 2004-11-29 Miklos Szeredi <miklos@szeredi.hu>
2705 * kernel: make readpage() uninterruptible
2707 * kernel: check readonly filesystem flag in fuse_permission
2709 * lib: don't die if version file not found and new style device
2712 * lib: add '-r' option, which is short for '-o ro'
2714 * fusermount: simplify device opening
2716 * kernel: when direct_io is turend on, copy data directly to
2717 destination without itermediate buffer. More efficient and safer,
2718 since no allocation is done.
2720 * fusermount: fix warning if fuse module is not loaded
2722 * kernel: use /dev/fuse on 2.4 too
2724 2004-11-26 Miklos Szeredi <miklos@szeredi.hu>
2726 * libfuse API change: open, read, write, flush, fsync and release
2727 are passed a 'struct fuse_file_info' pointer containing the open
2728 flags (open and release), and the file handle. Verion changed to
2731 2004-11-23 Miklos Szeredi <miklos@szeredi.hu>
2733 * More cleanups in the kernel
2735 * The 10,229 charater device number has been assigned for FUSE
2737 * Version file checking fix (reported by Christian Magnusson)
2739 * fusermount: opening the fuse device now doesn't need /sys.
2741 * Optimize reading by controlling the maximum readahead based on
2742 the 'max_read' mount option
2744 * fixes for UCLIBC (Christian Magnusson)
2746 2004-11-19 Miklos Szeredi <miklos@szeredi.hu>
2748 * Cleaned up kernel in preparation for merge into mainline:
2750 * Use /sys/fs/fuse/version instead of /proc/fs/fuse/version
2752 * Use real device (/dev/fuse) instead of /proc/fs/fuse/dev
2754 * __user annotations for sparse
2756 * allocate individual pages instead of kmalloc in fuse_readdir,
2757 fuse_read and fuse_write.
2759 * Fix NFS export in case "use_ino" mount option is given
2761 * Make libfuse and fusermount compatible with future versions
2763 * fusermount: properly add mount options to /etc/mtab
2765 2004-11-15 Miklos Szeredi <miklos@szeredi.hu>
2767 * fusermount: do not resolve last component of mountpoint on if it
2768 is '.' or '..'. This new path resolvation is now done on mount as
2769 well as unmount. This enables relative paths to work on unmount.
2771 * fusermount: parse common mount options like "ro", "rw", etc...
2773 * Allow module params to be changed through sysfs
2775 2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
2779 2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
2781 * Fix bug in fuse_readpages() causing Oops in certain situations.
2782 Bug found by Vincenzo Ciancia.
2784 * Fix compilation with kernels versions > 2.6.9.
2786 2004-11-11 Miklos Szeredi <miklos@szeredi.hu>
2788 * Check kernel interface version in fusermount to prevent
2789 strangeness in case of mismatch.
2791 * No need to allocate fuse_conn until actual mount happens
2793 * Fix potential race between umount and fuse_invalidate
2795 * Check superblock of proc file in addition to inode number
2797 * Fix race between request_send_noreply() and fuse_dev_release()
2799 2004-11-10 Miklos Szeredi <miklos@szeredi.hu>
2801 * Separate configure for the kernel directory
2803 * Don't allow write to return more than 'count'
2805 * Extend kernel interface for future use
2807 2004-11-09 Miklos Szeredi <miklos@szeredi.hu>
2809 * Fix 'makeconf.sh' to use autoreconf if available
2811 2004-11-08 Miklos Szeredi <miklos@szeredi.hu>
2813 * Add ino argument to 'fuse_dirfil_t'. NOTE: This breaks source
2814 compatibility with earlier versions. To compile earier versions
2815 just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
2816 Do not use the "use_ino" mount flag with filesystems compiled with
2819 * Add pkg-config support. To compile a FUSE based filesystem you
2820 can do "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
2821 or similar. Note, that the PKG_CONFIG_PATH environment variable
2822 usually needs to be set to "/usr/local/lib/pkgconfig".
2824 * fuse.h is now installed in ${prefix}/include/fuse/
2826 2004-11-02 Miklos Szeredi <miklos@szeredi.hu>
2828 * Added "use_ino" mount option. This enables the filesystems to
2829 set the st_ino field on files
2831 2004-11-01 Miklos Szeredi <miklos@szeredi.hu>
2833 * Fix compile problems with ancient (<=2.4.18) kernels (reported
2836 * Add "allow_root" mount option. Patch by Yaroslav Rastrigin
2838 * Clear the 'exited' flag when mail loop is finished
2840 2004-10-28 Miklos Szeredi <miklos@szeredi.hu>
2842 * Make xattr functions work under 2.6 (bug found by Vincenzo
2845 2004-10-26 Miklos Szeredi <miklos@szeredi.hu>
2847 * Reset request in fuse_flush() (bugreport by David Shaw)
2849 2004-10-21 Miklos Szeredi <miklos@szeredi.hu>
2851 * fuse_main() now does not exit on error, rather it returns an
2854 * Exported __fuse_setup() and __fuse_teardown() functions, which
2855 make it easier to implement a custom event loop.
2857 * Use daemon() call to background the filesystem after mounting.
2858 This function closes the standard input, output and error and
2859 changes the current working directory to "/".
2861 2004-10-14 Miklos Szeredi <miklos@szeredi.hu>
2865 2004-10-09 Miklos Szeredi <miklos@szeredi.hu>
2867 * Don't allow fuse_flush() to be interrupted (bug found by David
2870 2004-09-27 Miklos Szeredi <miklos@szeredi.hu>
2872 * Add PID to fuse_context. Patch by Steven James
2874 * Change file handle type to 'unsigned long' in kernel interface
2876 2004-09-22 Miklos Szeredi <miklos@szeredi.hu>
2878 * A slight API change: fuse_get_context() doesn't need the "fuse"
2879 pointer, but the returned context contains it instead. The
2880 fuse_get() function is not needed anymore, so it's removed.
2882 * Fix mounting and umounting FUSE filesystem under another FUSE
2883 filesystem by non-root (bug spotted by Valient Gough)
2885 2004-09-21 Miklos Szeredi <miklos@szeredi.hu>
2887 * Fix deadlock in case of memory allocation failure. Patch by
2890 2004-09-16 Miklos Szeredi <miklos@szeredi.hu>
2892 * Check memory allocation failures in libfuse
2894 2004-09-14 Miklos Szeredi <miklos@szeredi.hu>
2896 * Check temporary file creation failure in do_getdir(). Bug
2897 spotted by Terje Oseberg
2899 2004-09-13 Miklos Szeredi <miklos@szeredi.hu>
2901 * Allow "large_read" option for 2.6 kernels but warn of deprecation
2903 * Make requests non-interruptible so race with FORGET is avoided.
2904 This is only a temporary solution
2906 * Support compiling FUSE kernel module on 2.4.x UML kernels
2908 2004-09-09 Miklos Szeredi <miklos@szeredi.hu>
2910 * Fix bug in case two FORGETs for the same node are executed in
2911 the wrong order. Bug spotted and endured for months by Franco
2912 Broi, and logfile for solution provided by Terje Oseberg
2914 2004-09-01 Miklos Szeredi <miklos@szeredi.hu>
2916 * Add -D_REENTRANT to the compile flags
2918 * Add documentation of fuse internals by Terje Oseberg
2920 2004-08-16 Miklos Szeredi <miklos@szeredi.hu>
2922 * Change release method to be non-interruptible. Fixes bug
2923 causing missing release() call when program which has opened files
2924 is killed (reported by Franco Broi and David Shaw)
2926 2004-07-29 Miklos Szeredi <miklos@szeredi.hu>
2928 * Add fuse_invalidate() to library API
2930 2004-07-26 Miklos Szeredi <miklos@szeredi.hu>
2932 * Check permissions in setattr if 'default_permissions' flag is
2933 set. Bug spotted by Damjan Lango
2935 2004-07-24 Miklos Szeredi <miklos@szeredi.hu>
2937 * 'large_read' mount option removed for 2.6 kernels, since the
2938 default (dynamic read size) is better
2940 * Extend kernel API with file handles. A file handle is returned
2941 by open, and passed to read, write, flush, fsync and release.
2942 This is currently only used for debug output in the library.
2946 * Change the current directory to the mountpoint before checking
2947 the permissions and mount filesystem on "."
2949 * By default don't modprobe the fuse module for non-root. The old
2950 behavior can be restored with the '--enable-auto-modprobe' flag of
2953 * By default don't allow shared writable mappings for non-root.
2954 The old behavior can be restored with the 'user_mmap=1' module
2957 2004-07-23 Miklos Szeredi <miklos@szeredi.hu>
2959 * Clean up mount option passing to fusermount and to fuse_new()
2960 BEWARE: this changes the userspace API slightly, and the command
2961 line usage of programs using fuse_main()
2963 2004-07-20 Miklos Szeredi <miklos@szeredi.hu>
2965 * Optimize reading under 2.6 kernels by issuing multiple page
2966 asynchronous read requests
2968 2004-07-18 Miklos Szeredi <miklos@szeredi.hu>
2970 * Only use redirty_page_for_writepage() for kernels >= 2.6.6
2972 2004-07-16 Miklos Szeredi <miklos@szeredi.hu>
2974 * Separate directory entry and inode attribute validity timer
2976 * New write semaphore to stop page writeback during truncate
2978 * Fsync now waits for all writes to complete before sending the
2981 * Optimization: if a page is completely written by
2982 fuse_commit_write(), clear the dirty flag and set the uptodate
2985 * Some memory cleanup at exit
2987 2004-07-13 Miklos Szeredi <miklos@szeredi.hu>
2989 * Add FUSE_HARD_REMOVE flag, and '-i' option to fuse main, which
2990 disable the "hide if open" behavior of unlink/rename.
2992 * If temporary buffer allocation fails in raw read, fall back to a
2995 2004-07-12 Miklos Szeredi <miklos@szeredi.hu>
2997 * Fix bug in do_open() in libfuse: open count was incremented
2998 after the reply is sent so it could race with unlink/forget and
3001 2004-07-08 Miklos Szeredi <miklos@szeredi.hu>
3003 * When performing create or remove operation, refresh the parent's
3004 attributes on next revalidate, as i_nlink (and maybe size/time)
3007 * Use redirty_page_for_writepage() in fuse_writepage() for skipped
3010 * Set set_page_dirty address space operation (2.6 only)
3012 2004-07-06 Miklos Szeredi <miklos@szeredi.hu>
3014 * Minor fix in read: print debug info even if read size is zero
3016 2004-07-04 Miklos Szeredi <miklos@szeredi.hu>
3018 * Fix race between truncate and writepage (fsx-linux now runs
3021 2004-07-02 Miklos Szeredi <miklos@szeredi.hu>
3023 * Fix kernel hang on mkfifo under 2.4 kernels (spotted and patch
3026 * Added option for direct read/write (-r)
3028 * Fix revalidate time setting for newly created inodes
3030 * Remove uid==0 check for '-x' option in fusermount (kernel checks
3033 * fuse_main() only installs handlers for signals (out of INT, HUP,
3034 TERM, PIPE), for which no handler has yet been installed
3036 * Add module option 'user_allow_other' which if set to non-zero
3037 will allow non root user to specify the 'allow_other' mount option
3038 ('-x' option of fusermount)
3040 * Fix deadlock between page writeback completion and truncate
3041 (bug found by Valient Gough with the fsx-linux utility)
3043 2004-07-01 Miklos Szeredi <miklos@szeredi.hu>
3045 * Change passing fuse include dir to 2.6 kernel make system more
3046 robust (fixes compile problems seen on SuSE 9.1 with updated 2.6
3049 2004-06-30 Miklos Szeredi <miklos@szeredi.hu>
3051 * Acquire inode->i_sem before open and release methods to prevent
3052 concurrent rename or unlink operations.
3054 * Make __fuse_read_cmd() read only one command. This allows
3055 multiplexing the fuse file descriptor with other event sources
3056 using select() or poll() (patch by Jeff Harris)
3058 * Export 'exited' flag with __fuse_exited() (patch by Jeff Harris)
3060 2004-06-27 Miklos Szeredi <miklos@szeredi.hu>
3062 * Fix file offset wrap around at 4G when doing large reads
3064 2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
3066 * Fix memory leak in open (Valient Gough)
3068 2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
3070 * Add "close after delete" support to libfuse (patch by Valient
3073 * Cancel all worker threads before exit in multithreaded mode
3075 2004-06-23 Miklos Szeredi <miklos@szeredi.hu>
3079 * Don't send reply to RELEASE
3081 * Work with newer libtool (1.5a)
3083 * Check for st_atim member of struct stat
3085 2004-06-22 Miklos Szeredi <miklos@szeredi.hu>
3087 * No request allocation needed on inode and file release
3089 2004-06-21 Miklos Szeredi <miklos@szeredi.hu>
3091 * Fix possible inode leak in userspace in case of unfinished
3092 lookup/mknod/mkdir/symlink/link operation.
3094 2004-06-20 Miklos Szeredi <miklos@szeredi.hu>
3096 * Fix some races and cleanups in fuse_read_super()
3098 2004-06-19 Miklos Szeredi <miklos@szeredi.hu>
3100 * Requests are allocated at open time
3102 2004-06-03 Miklos Szeredi <miklos@szeredi.hu>
3104 * Build shared library as well as static (using libtool)
3106 * Change FUSE_MINOR_VERSION from 1 to 0. I know it's illegal but
3107 there has not been a release with the previous minor number, and I
3108 hope nobody is using it for anything.
3110 * Change fuse_main(), so that default behavior is to go into
3111 background if mount is successful. '-f' and '-d' options disable
3112 backgrounding. This fixes the "Why does my FUSE daemon hang?"
3115 * Cache ENOSYS (function not implemented) errors on *xattr, flush
3118 * Don't call getdir method from open() only from first readdir().
3119 Open is sometimes just used to store the current directory
3122 2004-05-18 Miklos Szeredi <miklos@szeredi.hu>
3124 * Added flush() call
3126 2004-05-04 Miklos Szeredi <miklos@szeredi.hu>
3128 * Extended attributes support for 2.4 (patch by Cody Pisto)
3130 2004-04-20 Miklos Szeredi <miklos@szeredi.hu>
3132 * Fixed parser with modversions (Mattias Wadman)
3134 2004-04-19 Miklos Szeredi <miklos@szeredi.hu>
3136 * Added mount option parser to 2.4 build
3138 2004-04-13 Miklos Szeredi <miklos@szeredi.hu>
3140 * Replaced binary mount data with text options
3142 * Show FUSE specific mount options in /proc/mounts
3144 * Check in fuse.h whether _FILE_OFFSET_BITS is set to 64
3146 2004-04-09 Miklos Szeredi <miklos@szeredi.hu>
3148 * Check some limits so userspace won't get too big requests
3150 2004-04-05 Miklos Szeredi <miklos@szeredi.hu>
3152 * Kill compile warning
3154 * Upgraded user-mount patch for 2.6.5
3156 2004-04-02 Miklos Szeredi <miklos@szeredi.hu>
3158 * Add detection of user-mode-linux to configure
3160 2004-03-31 Miklos Szeredi <miklos@szeredi.hu>
3162 * fixed zero size case for getxattr and listxattr
3164 2004-03-30 Miklos Szeredi <miklos@szeredi.hu>
3166 * new fusermount flag '-z': lazy unmount, default is not lazy
3168 * Extended attributes operations added (getxattr, setxattr,
3169 listxattr, removexattr)
3171 2004-03-25 Miklos Szeredi <miklos@szeredi.hu>
3173 * If filesystem doesn't define a statfs operation, then an
3174 all-zero default statfs is returned instead of ENOSYS
3176 2004-03-24 Miklos Szeredi <miklos@szeredi.hu>
3178 * Add FS_BINARY_MOUNTDATA filesystem flag for kernels > 2.6.4
3180 2004-03-09 Miklos Szeredi <miklos@szeredi.hu>
3182 * Fix for uClinux (Christian Magnusson)
3184 2004-03-02 Miklos Szeredi <miklos@szeredi.hu>
3186 * fuse_main() adds "-n progname" to the fusermount command line
3188 * More kernel interface changes:
3190 * Lookup/getattr return cache timeout values
3192 2004-02-25 Miklos Szeredi <miklos@szeredi.hu>
3194 * Clean up option parsing in fuse_main()
3196 * Added fuse_get() function which returns the fuse object created
3199 2004-02-20 Miklos Szeredi <miklos@szeredi.hu>
3201 * removed old way of mounting (fusermount mountpoint program)
3203 * more kernel interface changes:
3205 * added nanosecond precision to file times
3207 * removed interface version from mount data
3209 * added /proc/fs/fuse/version which contains MAJOR.MINOR
3211 2004-02-19 Miklos Szeredi <miklos@szeredi.hu>
3213 * statfs library API changed to match other methods. Since this
3214 is not backward compatible FUSE_MAJOR_VERSION is changed to 2
3216 * kernel interface changes follow:
3218 * statfs changed to 64 bits, added 'bavail' field
3220 * add generation number to lookup result
3222 * optimized mknod/mkdir/symlink/link (no separate lookup is
3225 * rdev size increased to 32 bits for mknod
3227 * kernel interface version changed to 3.1
3229 2004-02-18 Miklos Szeredi <miklos@szeredi.hu>
3231 * user-mount upgraded for 2.6.3 kernel
3233 2004-02-17 Miklos Szeredi <miklos@szeredi.hu>
3235 * Added user-mount.2.6.2-rc3.patch
3237 * Add FS_SAFE flag to fuse filesystem
3239 * fusermount should allow (un)mounting for non-root even if not
3242 2004-02-12 Miklos Szeredi <miklos@szeredi.hu>
3244 * Remove MS_PERMISSION mount flag (that means something else now)
3246 2004-02-10 Miklos Szeredi <miklos@szeredi.hu>
3248 * Added check for i_size_read/write functions to configure.in
3249 (patch by Valient Gough)
3251 2004-02-06 Miklos Szeredi <miklos@szeredi.hu>
3253 * Fixed writing >= 2G files
3255 * Check file size on open (with generic_file_open())

3261 * Make loopback mount of a fuse file work
3263 2004-02-04 Miklos Szeredi <miklos@szeredi.hu>
3267 2004-01-29 Miklos Szeredi <miklos@szeredi.hu>
3269 * Properly check if the inode exists in fuse_invalidate
3271 2004-01-27 Miklos Szeredi <miklos@szeredi.hu>
3273 * Added -q option for fusermount
3275 * fuse_unmount() now uses -q option of fusermount, so no error is
3276 printed if the cause of the program exit is that the filesystem
3277 has already been unmounted
3279 * Fix i_nlink correctness after rmdir/unlink
3281 2004-01-26 Miklos Szeredi <miklos@szeredi.hu>

3297 * Write all pending data before a RELEASE operation
3299 * Suppress 'Bad file descriptor' warning on exit
3301 * Replaced fusermount option '-d xxx' with '-n xxx' so it doesn't
3302 get confused with '-d' of fuse_main() (sorry about this change)
3304 * New fusermount option '-l' which enables big reads. Big reads
3305 are now disabled by default.
3307 * fuse_main() can accept fusermount arguments after a '--'
3309 2004-01-19 Miklos Szeredi <miklos@szeredi.hu>

3364 * Add file locking for mount/unmount (based on patch by Valient
3367 2003-12-11 David McNab <david@rebirthing.co.nz>
3369 * Python filesystem - was broken with python2.3, now fixed:
3370 - changed PyTuple_* calls to PySequence_*, because os.lstat
3371 is no longer returning a pure tuple
3372 - changed PyInt_Check() calls to also call PyLong_Check,
3373 to cover for cases (eg os.lstat) where longs are returned
3374 - Added support for file 'release' handling, which IMO is
3375 essential since this signals to a FS that writes to a file
3376 are complete (and therefore the file can now be disposed of
3377 meaningfully at the python filesystem's discretion)
3378 - Added '__init__' handler to base Fuse class, which allows
3379 your Python class to know the mountpoint and mount args,
3380 as attributes myfs.mountpoint, myfs.optlist, myfs.optdict
3383 - added 'mount.fuse' script (in util/ dir), which is meant to be
3384 symlinked from /sbin, and which allows FUSE filesystems to
3385 be mounted with the 'mount' command, and listed in fstab;
3386 also, mount arguments get passed to your filesystem
3389 2003-11-04 Miklos Szeredi <miklos@szeredi.hu>
