2 =======================
4 * Tarball now includes documentation.
5 * Shared-object version has now been bumped correctly.
7 FUSE 2.9.5 (2016-01-14)
8 =======================
10 * New maintainer: Nikolaus Rath <Nikolaus@rath.org>. Many thanks to
11 Miklos Szeredi <miklos@szeredi.hu> for bringing FUSE to where it is
14 * fix warning in mount.c:receive_fd(). Reported by Albert Berger
16 * fix possible memory leak. Reported by Jose R. Guzman
18 FUSE 2.9.4 (2015-05-22)
19 =======================
21 * fix exec environment for mount and umount. Found by Tavis Ormandy
24 * fix fuse_remove_signal_handlers() to properly restore the default
25 signal handler. Reported by: Chris Johnson
27 * highlevel API: fix directory file handle passed to ioctl() method.
28 Reported by Eric Biggers
30 * libfuse: document deadlock avoidance for fuse_notify_inval_entry()
31 and fuse_notify_delete()
33 * fusermount, libfuse: send value as unsigned in "user_id=" and
34 "group_id=" options. Uids/gids larger than 2147483647 would result
35 in EINVAL when mounting the filesystem. This also needs a fix in
38 * Initilaize stat buffer passed to ->getattr() and ->fgetattr() to
39 zero in all cases. Reported by Daniel Iwan
41 * libfuse: Add missing includes. This allows compiling fuse with
42 musl. Patch by Daniel Thau
45 Older Versions (before 2013-01-01)
46 ==================================
49 2013-06-20 Miklos Szeredi <miklos@szeredi.hu>
51 * libfuse: fix multiple close of device fd. Reported by Dan
54 2013-03-19 Miklos Szeredi <miklos@szeredi.hu>
56 * libfuse: fix thread cancel race. Exiting a worker my race with
57 cancelling that same worker. This caused a segmenation
58 fault. Reported and tested by Anatol Pomozov
60 2013-02-04 Miklos Szeredi <miklos@szeredi.hu>
62 * libfuse: fix crash in unlock_path(). Patch by Ratna Manoj
64 * libfuse: fix the 'remember' option. The lru list was not
65 initialized for the "/" path. This resulted in remove_node_lru()
66 crashing on LOOKUP-DOTDOT. Patch by Madan Valluri
68 * libfuse: configure: detect new util-linux
70 * libfuse: Use AC_CONFIG_HEADERS instead of AM_CONFIG_HEADER.
71 Patch by Anatol Pomozov
73 * libfuse: rename ./configure.in to ./configure.ac. Patch by
76 2012-10-01 Miklos Szeredi <miklos@szeredi.hu>
80 2012-10-01 Miklos Szeredi <miklos@szeredi.hu>
82 * Fix deadlock in libfuse. Running "svn update" on a fuse
83 filesystem could deadlock because of a bug in the way the paths
84 are locked. Reported by Kazuaki Anami
86 2012-08-23 Miklos Szeredi <miklos@szeredi.hu>
88 * Fix missing config.h in buffer.c. Reported by Matthew Gabeler-Lee
90 2012-08-14 Miklos Szeredi <miklos@szeredi.hu>
92 * Not unhashing the name in forget (commit on 2011-12-09) broke
93 the forget logic in a subtle way, resulting in "fuse internal
94 error: node NNN not found" and causing the filesystem daemon to
95 abort. Fix by incrementing the node refcount if nlookup goes from
96 zero to one. Reported by Kyle Lippincott
98 2012-08-13 Miklos Szeredi <miklos@szeredi.hu>
100 * Fix linking against GNU libiconv. Patch by Natanael Copa
102 2012-07-19 Miklos Szeredi <miklos@szeredi.hu>
106 2012-07-19 Miklos Szeredi <miklos@szeredi.hu>
108 * Fix crash caused by freeing a stack address. Reported by Itay
111 2012-07-04 Miklos Szeredi <miklos@szeredi.hu>
113 * Fix install of mount.fuse from out-of-tree build. Patch by
116 * Fix build with automake >= 1.12.1. Patch by Olivier Blin
118 2012-04-24 Miklos Szeredi <miklos@szeredi.hu>
120 * Add fallocate operation. Only works on linux kernels 3.5 or
121 later. Patch by Anatol Pomozov
123 2012-05-16 Miklos Szeredi <miklos@szeredi.hu>
125 * Linking to a library that uses threads requires the application
126 to be linked with -pthreads otherwise some pthread functions will
127 be linked to stubs in glibc. So move -pthread from Libs.private
128 to Libs in fuse.pc. Reported by Werner Fink
130 * Fix the compile command in the examples. Reported by Luciano
133 2012-04-20 Miklos Szeredi <miklos@szeredi.hu>
137 2012-04-20 Miklos Szeredi <miklos@szeredi.hu>
139 * Add missing fuse_fs_flock to fuse_versionscript
141 2012-04-10 Miklos Szeredi <miklos@szeredi.hu>
143 * Check protocol version before sending notifications and return
144 -ENOSYS if a particular notification is not supported.
146 * Add 'flag_utime_omit_ok' flag to fuse_operations. If the
147 filesystem sets this flag then ->utimens() will receive UTIME_OMIT
148 and UTIME_NOW values as specified in utimensat(2).
150 2012-01-27 Miklos Szeredi <miklos@szeredi.hu>
152 * Interpret octal escape codes in options. Requested by Jan
155 2012-01-26 Miklos Szeredi <miklos@szeredi.hu>
157 * Add man pages for fusermount, mount.fuse and ulockmgr_server.
158 Lifted from the Debian package. The man pages were written by
159 Daniel Baumann and Bastien Roucaries
161 2012-01-13 Miklos Szeredi <miklos@szeredi.hu>
163 * Disable symbol versions on MacOSX. Patch by Anatol Pomozov
165 2012-01-02 Miklos Szeredi <miklos@szeredi.hu>
167 * Remove unnecessary mutex unlock at the end of multithreaded
170 2011-12-09 Miklos Szeredi <miklos@szeredi.hu>
172 * Fix hang in wait_on_path(). Reported by Ville Silventoinen
174 * Don't unhash name in FORGET. This resulted in ENOENT being
175 returned for unlinked but still open files if the kernel sent a
176 FORGET request for the parent directory.
178 * Free request in fuse_reply_data().
180 2011-12-08 Miklos Szeredi <miklos@szeredi.hu>
182 * Fix build if FUSE_NODE_SLAB is not defined. Patch by Emmanuel
185 * Check for availability of utimensat() function. Patch by
188 2011-12-07 Miklos Szeredi <miklos@szeredi.hu>
190 * Add fuse_lowlevel_notify_delete() which tells the kernel that a
191 file or directory is deleted. Patch by John Muir
193 2011-12-06 Miklos Szeredi <miklos@szeredi.hu>
195 * Update retrieve_reply() method
197 2011-12-05 Miklos Szeredi <miklos@szeredi.hu>
199 * Low level API: lock argument of fuse_reply_lock should have a
200 'const' qualifier. Reported by Shachar Sharon
202 * Add support for ioctl on directories. Reported by Antonio SJ
205 2011-10-13 Miklos Szeredi <miklos@szeredi.hu>
207 * Reply to request with ENOMEM in case of failure to allocate
208 request structure. Otherwise the task issuing the request will
209 just freeze up until the filesystem daemon is killed. Reported by
212 2011-09-23 Miklos Szeredi <miklos@szeredi.hu>
214 * Replace daemon() function with fork(). Patch by Anatol Pomozov
216 2011-08-26 Miklos Szeredi <miklos@szeredi.hu>
218 * If configured with --disable-mtab then don't call mount(8) from
219 libfuse to update the mtab. Reported by: James Sierp
221 2011-08-24 Miklos Szeredi <miklos@szeredi.hu>
223 * Use LRU list for cleaning up the cache if the "remember=T"
224 option was given. Patch by therealneworld@gmail.com
226 2011-07-06 Miklos Szeredi <miklos@szeredi.hu>
228 * Add ->flock() operation to low and high level interfaces. This
229 fixes problems with emulating flock() with POSIX locking.
230 Reported by Sebastian Pipping. As with lock/setlk/getlk most
231 filesystems don't need to implement this, as the kernel takes care
232 of file locking. The only reason to implement locking operations
233 is for network filesystems which want file locking to work between
236 2011-07-02 Sebastian Pipping <sebastian@pipping.org>
238 * Make xmp_utimens of examples "fusexmp" and "fusexmp_fh"
239 not follow symlinks as other layers do that already.
241 2011-06-02 Miklos Szeredi <miklos@szeredi.hu>
243 * Add "remember" option. This works similar to "noforget" except
244 that eventually the node will be allowed to expire from the cache.
245 Patch by therealneworld@gmail.com
247 2011-05-27 Miklos Szeredi <miklos@szeredi.hu>
249 * Check if splice/vmsplice are supported
251 2011-05-26 Miklos Szeredi <miklos@szeredi.hu>
253 * Remove -lrt -ldl from fuse.pc for dynamic linking since
254 libfuse.so is already linked with these libraries. Reported by:
257 2011-05-20 Miklos Szeredi <miklos@szeredi.hu>
259 * Cleaner build output. Patch by Reuben Hawkins
261 2011-05-19 Miklos Szeredi <miklos@szeredi.hu>
263 * Disable splice by default, add "splice_read", "splice_write" and
264 "splice_move" options. Keep the "no_splice_*" variants, which can
265 disable splice even if the filesystem explicitly enables it.
267 2011-04-15 Max Krasnyansky <maxk@kernel.org>
268 * Added support for "auto_unmount" option which unmounts the
269 filesystem automatically on process exit (or crash).
271 2011-03-30 Miklos Szeredi <miklos@szeredi.hu>
273 * Patches by Laszlo Papp fixing various issues found by the
276 2011-03-11 Miklos Szeredi <miklos@szeredi.hu>
278 * In case of failure to add to /etc/mtab don't umount. Reported
281 2011-02-02 Miklos Szeredi <miklos@szeredi.hu>
283 * libfuse: In fuse_session_loop_mt() don't pause when exiting the
284 worker threads. The pause() was added in 2.2.1 to prevent
285 segfault on pthread_cancel() on an exited, detached thread. Now
286 worker threads are not detached and pthread_cancel() should work
287 fine even after the thread exited. Reported by Boris Protopopov
289 2011-01-31 Miklos Szeredi <miklos@szeredi.hu>
291 * fusermount: chdir to / before performing mount/umount
293 * fusermount: only allow mount and umount if util-linux supports
296 2010-12-16 Miklos Szeredi <miklos@szeredi.hu>
298 * Highlevel lib: allow hash tables to shrink
300 * Highlevel lib: add slab allocation for node cache. This will
301 allow the memory used by the filesystem to grow and shrink
302 depending on how many inodes are currently cached.
304 2010-12-13 Miklos Szeredi <miklos@szeredi.hu>
306 * Highlevel lib: use dynamically resized hash table for looking up
309 2010-12-07 Miklos Szeredi <miklos@szeredi.hu>
311 * Allow batching of forget requests. This allows forget requests
312 to be processed faster and doesn't require a modification to fuse
313 filesystems. Reported by Terje Malmedal
315 * Add ->forget_multi() operation to the lowlevel API. The
316 filesystem may implement this to process multiple forget requests
319 * Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
320 for 32bit vs. 64bit userspace
322 2010-11-10 Miklos Szeredi <miklos@szeredi.hu>
324 * Add new write_buf() method to the highlevel API. Similarly to
325 the lowlevel write_buf() method, this allows implementing zero
328 * Add a new read_buf() method to the highlevel API. This allows
329 returning a generic buffer from the read method, which in turn
330 allows zero copy reads.
332 * In fusexmp_fh implement the ->read_buf() and ->write_buf()
333 methods. Leave the ->read() and ->write() implementations for
334 reference, even though they are not necessary.
336 2010-11-08 Miklos Szeredi <miklos@szeredi.hu>
338 * Fix check for read-only fs in mtab update
340 * Open /dev/null for write instead of read for redirecting stdout
343 * If umount(8) supports --fake and --no-canonicalize (util-linux-ng
344 version 2.18 or later), and umount(2) supports the
345 UMOUNT_NOFOLLOW flag (linux kernel version 2.6.35 or later) then,
346 "fusermount -u" will call the umount(2) system call and use
347 "umount --fake ..." to update /etc/mtab
349 * Added --disable-legacy-umount option to configure. This
350 disables the runtime checking of umount(8) version. When built
351 with this option then "fusermount -u" will fail if umount(8)
352 doesn't support the --fake and --no-canonicalize options.
354 * Fix fuse_buf_copy() if already at the end of the buffers
356 * Add new ->write_buf() method to low level interface. This
357 allows passig a generic buffer, either containing a memory buffer
358 or a file descriptor. This allows implementing zero copy writes.
360 * Add fuse_session_receive_buf() and fuse_session_process_buf()
361 which may be used in event loop implementations to replace
362 fuse_chan_recv() and fuse_session_process() respectively.
364 * Remove unnecessary restoring of current working directory in
367 * Add ctx->pid to debug output
369 * Fix st_nlink value in high level lib if file is unlinked but
372 * libfuse: add store request. Request data to be stored in the
373 kernel buffers for a given inode.
375 * libfuse: add retrieve request. Retrieve data stored in the
376 kernel buffers for a given inode.
378 2010-10-14 Miklos Szeredi <miklos@szeredi.hu>
380 * Use LTLIBICONV when linking libfuse. This fixes building against
381 uclibc + libiconv. Patch by Natanael Copa
383 2010-10-05 Miklos Szeredi <miklos@szeredi.hu>
385 * Add missing argument check in ulockmgr.c to prevent calling
386 ulockmgr_server with illegal arguments. This would cause an ever
387 growing list of ulockmgr_server processes with an endless list of
388 open files which finally exceeds the open file handle limit.
389 Patch by Markus Ammer
391 2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
393 * Fix ambiguous symbol version for fuse_chan_new.
394 fuse_versionscript included fuse_chan_new in both FUSE_2.4 and
395 FUSE_2.6. Remove the FUSE_2.4, which is invalid.
397 2010-09-28 Miklos Szeredi <miklos@szeredi.hu>
399 * Fix option escaping for fusermount. If the "fsname=" option
400 contained a comma then the option parser in fusermount was
401 confused (Novell bugzilla #641480). Fix by escaping commas when
402 passing them over to fusermount. Reported by Jan Engelhardt
404 2010-08-27 Miklos Szeredi <miklos@szeredi.hu>
406 * Add NetBSD support. Patch from Emmanuel Dreyfus
408 2010-07-12 Miklos Szeredi <miklos@szeredi.hu>
410 * libfuse: add buffer interface. Add a generic buffer interface
411 for use with I/O. Buffer vectors are supplied and each buffer in
412 the vector may be a memory pointer or a file descriptor.
414 * The fuse_reply_fd() interface is converted to using buffers.
416 2010-06-23 Miklos Szeredi <miklos@szeredi.hu>
418 * Make the number of max background requests and congestion
419 threshold tunable. New options are "max_background" and
420 "congestion_threshold". Only effective on linux kernel versions
421 2.6.32 or greater. Patch by Csaba Henk
423 2010-06-17 Miklos Szeredi <miklos@szeredi.hu>
425 * Add fuse_reply_fd() reply function to the low level interface.
426 On linux version 2.6.35 or greater this will use splice() to move
427 data directly from a file descriptor to the fuse device without
428 needing to go though a userspace buffer. With the
429 FUSE_REPLY_FD_MOVE flag the kernel will attempt to move the data
430 directly into the filesystem's cache. On earlier kernels it will
431 fall back to an intermediate buffer. The options
432 "no_splice_write" and "no_splice_move" can be used to disable
433 splicing and moving respectively.
435 2010-06-15 Miklos Szeredi <miklos@szeredi.hu>
437 * Fix out-of-source build. Patch by Jörg Faschingbauer
439 * Add a "nopath" option and flag, indicating that path argument
440 need not be calculated for the following operations: read, write,
441 flush, release, fsync, readdir, releasedir, fsyncdir, ftruncate,
442 fgetattr, lock, ioctl and poll.
444 2010-05-10 Miklos Szeredi <miklos@szeredi.hu>
446 * Remove "chmod root" from install of fusermount. Reported by
449 2010-04-26 Miklos Szeredi <miklos@szeredi.hu>
453 2010-04-26 Miklos Szeredi <miklos@szeredi.hu>
455 * Fix checking for symlinks in umount from /tmp. Reported by Al
458 * Fix umounting if /tmp is a symlink. Reported by Franco Broi
460 2010-02-18 Miklos Szeredi <miklos@szeredi.hu>
462 * Fix definition of FUSE_OPT_END for C++. Reported by Tim
465 2010-02-03 Miklos Szeredi <miklos@szeredi.hu>
467 * Fix stack alignment for clone()
469 2010-02-01 Miklos Szeredi <miklos@szeredi.hu>
473 2010-02-01 Miklos Szeredi <miklos@szeredi.hu>
475 * Using "--no-canonicalize" with umount(8) conflicts with the race
476 fix, sinceit assumes the supplied path is absolute, while the race
477 fix relies on the path being relative to the current directory.
478 Reported by Tom Rindborg
480 2010-01-26 Miklos Szeredi <miklos@szeredi.hu>
484 2010-01-21 Miklos Szeredi <miklos@szeredi.hu>
486 * Fix race if two "fusermount -u" instances are run in parallel.
487 Reported by Dan Rosenberg
489 * Make sure that the path to be unmounted doesn't refer to a
492 2010-01-14 Miklos Szeredi <miklos@szeredi.hu>
494 * Fix compile error on FreeBSD. Patch by Jay Sullivan
496 2009-12-17 Miklos Szeredi <miklos@szeredi.hu>
498 * Use '--no-canonicalize' option of mount(8) (available in
499 util-linux-ng version 2.17 or greater) to avoid calling
500 readling(2) on the newly mounted filesystem before the mount
501 procedure is finished. This has caused a deadlock if "audit" was
502 enabled in the kernel. Also use '--no-canonicalize' for umount to
503 avoid touching the mounted filesystem.
505 2009-09-11 Miklos Szeredi <miklos@szeredi.hu>
509 2009-08-25 Miklos Szeredi <miklos@szeredi.hu>
511 * Fix missing versioned symbol fuse_get_context@FUSE_2.2
513 2009-08-18 Miklos Szeredi <miklos@szeredi.hu>
517 2009-08-18 Miklos Szeredi <miklos@szeredi.hu>
519 * Add missing fuse_session_data to versionscript
521 * Make sure all global symbols are prefixed with "fuse_" or "cuse_"
523 2009-07-16 Miklos Szeredi <miklos@szeredi.hu>
525 * Clarify how the protocol version should be negotiated between
526 kernel and userspace. Notably libfuse didn't correctly handle the
527 case when the supported major versions didn't match
529 * Add missing pthread link for libulockmgr. Patch by Petr Salinger
531 2009-07-02 Miklos Szeredi <miklos@szeredi.hu>
533 * The context is extended with a 'umask' field. The umask is sent
534 for mknod, mkdir and create requests by linux kernel version
535 2.6.31 or later, otherwise the umask is set to zero. Also
536 introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel
537 supports this feature, then this flag will be set in conn->capable
538 in the ->init() method. If the filesystem sets this flag in in
539 conn->want, then the create modes will not be masked.
541 * Add low level interfaces for lookup cache and attribute
542 invalidation. This feature is available in linux kernels 2.6.31
543 or later. Patch by John Muir
545 * Kernel interface version is now 7.12
547 * fusermount: Do not silently ignore command line arguments.
548 Patch by Sebastian Harl
550 2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
552 * Released 2.8.0-pre3
554 2009-06-19 Miklos Szeredi <miklos@szeredi.hu>
556 * Add fuse_getgroups (high level lib) and fuse_req_getgroups (low
557 level lib) functions to query the supplementary group IDs for the
558 current request. Currently this is implemented on Linux by
559 reading from the /proc filesystem.
561 2009-06-18 Miklos Szeredi <miklos@szeredi.hu>
563 * Add "noforget" option to high level lib to prevent ESTALE errors
564 on NFS exported filesystems. This result in paths being cached
565 forever, resulting in ever growing memory usage. Use with care.
567 * Add "no_remote_lock" option to disable remote file locking even
568 if the filesystem implements it. With this option locking
569 primitives (flock, lockf, fcntl(F_SETLK)) will still work, but
570 will ignore remotely locked files.
572 * CUSE patches from Tejun Heo:
574 * Unrestricted ioctl support left some debris. Clean them up:
575 o No reason to pass around pointer to flags. Pass flags directly.
576 o Clean up comment and prototype parameter names.
577 o fuse_lib_ioctl() didn't reply when get_path() failed. Fix it.
578 o Remove unused variables {in|out}_iov from fuse_lib_ioctl().
580 * Add fuse_reply_ioctl_iov()
582 * Move fuse_session, fuse_req and fuse_ll definitions to fuse_i.h
583 and make send_reply_iov() and fuse_setup_common() global (also in
584 fuse_i.h). These will be used by CUSE support.
586 * Restructure fuse_ll_process()
588 * Implement libfuse side of CUSE support. CUSE uses subset of FUSE
589 operations as dir operations don't make sense for CUSE where one
590 instance implements single character device.
592 CUSE support comes with its own cuse_lowevel_ops and related
593 initialization and helper functions. Except for initialization, it
594 usage is basically identical to FUSE.
596 This patch also adds example/cusexmp.c which can create a character
597 device with name and device number specified on command line. The
598 created device itself is pretty boring. It's a bit bucket supporting
599 read, write and access via ioctl.
601 2009-06-16 Miklos Szeredi <miklos@szeredi.hu>
603 * Add missing fuse_reply_bmap to versionscript. Debian
604 Bug#531329. Reported by Goswin Brederlow
606 2009-05-27 Miklos Szeredi <miklos@szeredi.hu>
608 * Don't call forget_node() if the lookup was negative and write()
609 for the reply returned ENOENT. Reported by John Haxby
611 2009-05-25 Miklos Szeredi <miklos@szeredi.hu>
613 * Add FUSE_CAP_EXPORT_SUPPORT to fuse_common.h
615 2009-05-08 Miklos Szeredi <miklos@szeredi.hu>
617 * Fix missing newlines in some printfs
619 * Fix 'make install-strip'. Reported by Dominick Layfield
621 2009-01-05 Miklos Szeredi <miklos@szeredi.hu>
623 * Released 2.8.0-pre2
625 2008-12-08 Miklos Szeredi <miklos@szeredi.hu>
627 * Implement poll support. Patch by Tejun Heo
629 * Add missing setattr flags to <fuse_lowlevel.h>.
631 * Only pass valid flags to ->setattr().
633 2008-12-05 Miklos Szeredi <miklos@szeredi.hu>
635 * Implement ioctl support. On high level interface only
636 "restricted" ioctls are supported (which are defined with the
637 _IO(), _IOR(), _IOW() or _IOWR() macros). Unrestricted ioctls
638 will only be allwed to CUSE (Character Device in Userspace)
639 servers. Patch by Tejun Heo

643 * If open sets fi->nonseekable, libfuse will tell the kernel that
644 the file is not seekable. Patch by Tejun Heo
646 2008-11-19 Miklos Szeredi <miklos@szeredi.hu>
648 * lowlevel lib: fix deadlock if fuse_reply_* is called from the
649 interrupt handling function. Reported by Tero Marttila
651 2008-10-16 Miklos Szeredi <miklos@szeredi.hu>
653 * Allow commas in options to be escaped with a backslash
655 * Add new function: fuse_opt_add_opt_escaped()
657 * Add missing fuse_reply_bmap() to the version script
659 2008-10-14 Miklos Szeredi <miklos@szeredi.hu>

669 * Released 2.8.0-pre1
671 2008-06-27 Miklos Szeredi <miklos@szeredi.hu>
673 * Fix handling of (no)suid and (no)dev options if filesystem is
674 mounted from /etc/fstab or via mount(8). Reported by Jan Ondrej.
676 * Skip calling mount(8) if /etc/mtab doesn't exist or if it's on a
677 read-only filesystem. This works around issues with certain mount
678 implementations. Reported by Szabolcs Szakacsits.
680 2008-06-16 Miklos Szeredi <miklos@szeredi.hu>
682 * Remove fuse kernel module sources. Linux 2.6.27 will support
685 2008-06-10 Miklos Szeredi <miklos@szeredi.hu>
687 * Fix theoretical infinite loops in libfuse. Reported by Szabolcs

695 * Fix mounting over symlink. Reported by Szabolcs Szakacsits
697 2008-05-09 Miklos Szeredi <miklos@szeredi.hu>
699 * Don't allow bigger than 4kB writes by default on 2.6.26 and
700 later kernels, so that filesystems not expecting this are not
701 broken on a kernel upgrade. Provide a 'big_writes' mount option
702 to enable this feature. In future API revisions this may become
705 2008-04-09 Miklos Szeredi <miklos@szeredi.hu>
707 * Update warning message for missing newline at end of fuse.conf
709 * Update debug message for successful operation to not include the

723 2008-03-25 Miklos Szeredi <miklos@szeredi.hu>
725 * Fix memory leaks on mount. Patch by Szabolcs Szakacsits
727 2008-03-19 Miklos Szeredi <miklos@szeredi.hu>
729 * Fix missing pthread_mutex_destroy in error path of
730 fuse_lib_opendir(). Patch by Szabolcs Szakacsits
732 2008-03-07 Miklos Szeredi <miklos@szeredi.hu>
734 * Add queuing on contention to per-node lock algorithm, to avoid
737 * Only enable cancelation when reading a request, otherwise
738 cancellation could happen with a mutex held, which could hang the
741 2008-02-08 Miklos Szeredi <miklos@szeredi.hu>
743 * Block SIGCHLD when executing mount and umount
745 * fusexmp_fh: avoid unnecessary seeking in readdir
747 * Update kernel interface to 7.9:
749 * Support receiving file handle from kernel in GETATTR request
751 * Allow operations with a NULL path argument, if the filesystem
754 * Add support atomic open(O_TRUNC)
756 * Support the st_blksize field in struct stat
758 * If the "FUSE_THREAD_STACK" environment is set, initialize the
759 stack size of threads by this value. Patch by Florin Malita
761 * Add per-node locking, instead of a global tree lock to protect
762 the path from changing during operations. Original patch by
765 2008-02-03 Csaba Henk <csaba.henk@creo.hu>
768 - string formatting fixes
769 - exit if mounting has failed
770 (in FreeBSD a mount failure is not critical per se, as the daemon
771 still could be mounted externally, but waiting for such an event
772 is more confusing than fruitful)
773 - ditch the kvm(8) stuff and simply use forced unmount which just
775 - prettify option specifications
776 - add "-onosync_unmount" kernel option
778 2008-01-07 Csaba Henk <csaba.henk@creo.hu>
781 - refine device closing in a race-free way
782 - add support for "-osubtype" on FreeBSD
784 * makeconf.sh: make it work under FreeBSD
786 2008-01-03 Csaba Henk <csaba.henk@creo.hu>
788 * lib/mount_bsd.c: close device before unmount
789 (cf. lib/mount.c rev. 1.43) and fix some warnings
791 2007-12-23 Miklos Szeredi <miklos@szeredi.hu>
793 * Fix './configure --disable-static'. Patch from Ismail Dönmez
795 2007-12-17 Miklos Szeredi <miklos@szeredi.hu>
799 2007-12-12 Miklos Szeredi <miklos@szeredi.hu>
801 * Fix kernel module compile for 2.6.24
803 * Invalidate attributes of parent directory after create(), since
804 the modification time changes. Invalidate attributes on rename,
805 since some filesystems may update st_ctime. Reported by Szabolcs
808 * Fix NFS exporting to handle 64bit node IDs
810 * Disable old symbol versions if __UCLIBC__ is defined. If a
811 symbol in a library has multiple versions, the runtime linker in
812 uClibc seems to randomly choose between them.
814 * Remove erroneous 'fuse_opt_insert_arg@FUSE_2_5' from
815 fuse_version_script. fuse_opt_free_args() was added in fuse-2.6.
817 * Close fuse device file descriptor before calling umount(),
818 preventing a deadlock when umount is synchronous. Reported by
821 2007-11-12 Miklos Szeredi <miklos@szeredi.hu>
823 * 'fusermount -u' did not umount the filesystem if /etc/mtab was a
824 symlink. This bug was introduced in 2.7.1 by "Don't call
825 /bin/[u]mount if /etc/mtab is a symlink". Found by robertsong.

843 2007-09-18 Miklos Szeredi <miklos@szeredi.hu>
845 * Add missing context initialization in fuse_fs_chmod(). Bug
848 * Fix kernel module compilation for 2.6.23. Based on patch by
851 2007-09-04 Philippe Elie <phil.el@wanadoo.fr>
853 * lib/fuse_lowlevel.c: fix a fuse_req leak in do_forget()
855 2007-07-31 Miklos Szeredi <miklos@szeredi.hu>
857 * Work around hotplug issue, that it calls filesystem with file
858 descriptors 0, 1 and 2 not open. Tracked down by Leif Johnson
860 2007-07-25 Miklos Szeredi <miklos@szeredi.hu>
862 * Don't call /bin/[u]mount if /etc/mtab is a symlink. Reported by
865 * Also don't touch /etc/mtab if it is within the mounted
866 filesystem. Suggested by Jeffrey Law
868 2007-07-12 Miklos Szeredi <miklos@szeredi.hu>
870 * Reset args->argc in fuse_opt_free_args(). Patch by Lucas
873 2007-07-02 Miklos Szeredi <miklos@szeredi.hu>
877 2007-07-02 Miklos Szeredi <miklos@szeredi.hu>
879 * Accept a NULL "op" for fuse_main(), etc. This is useful if
880 filesystem is only invoking fuse to print a help message, or
881 version. Fixes RedHat bugzilla #217343
883 2007-06-22 Miklos Szeredi <miklos@szeredi.hu>
885 * lib: fix locking when loading a filesystem module
887 2007-06-21 Miklos Szeredi <miklos@szeredi.hu>
889 * Add fs subtype support to mount.fuse

893 * Add fs subtype support to libfuse and fusermount
895 2007-06-19 Miklos Szeredi <miklos@szeredi.hu>
897 * kernel: sync with mainline (2.6.22)
899 2007-06-18 Miklos Szeredi <miklos@szeredi.hu>
901 * Send debug output to stderr instead of stdout. Patch by Jan
904 2007-06-03 Miklos Szeredi <miklos@szeredi.hu>
906 * libulockmgr: Work around a kernel bug in recv(), causing it to
907 sometimes return zero even if data was available on the socket.
909 2007-05-29 Miklos Szeredi <miklos@szeredi.hu>
911 * lib: optimization: store parent pointer in node instead of
914 2007-05-25 Miklos Szeredi <miklos@szeredi.hu>
916 * lib: don't create new thread for each FORGET request. FORGET
917 messages sometimes caused so many threads to be created, that
918 process virtual memory space ran out. Reported by Chris AtLee
920 2007-05-24 Miklos Szeredi <miklos@szeredi.hu>
922 * lib: fix memory leak on thread creation failure in multithreaded
923 event loop. Found by Chris AtLee
925 2007-05-23 Miklos Szeredi <miklos@szeredi.hu>
927 * lowlevel lib: add fuse_reply_iov function, which is similar to
928 fuse_reply_buf, but accepts a vector of buffers. Patch by Roger
931 2007-05-21 Miklos Szeredi <miklos@szeredi.hu>
933 * Fix Oops or error if a regular file is created with mknod(2) on
934 a fuse filesystem. Kernels 2.6.18 onward are affected. Thanks to
935 J. Cameijo Cerdeira for the report
937 2007-05-11 Csaba Henk <csaba.henk@creo.hu>
939 * libfuse: fix return value of fuse_loop()/fuse_loop_mt().
940 Error reported by Csaba Henk, fix by Miklos Szeredi
942 * libfuse: fix unlock in flush
944 * libfuse: do unlocking on RELEASE+FLUSH
946 2007-05-03 Miklos Szeredi <miklos@szeredi.hu>
950 2007-05-02 Miklos Szeredi <miklos@szeredi.hu>
952 * kernel: sync with mainline:
954 * Use invalidate_mapping_pages() if available
956 * Fix BUG when invalid file type is supplied in mount. Patch by
959 2007-04-27 Miklos Szeredi <miklos@szeredi.hu>
961 * libfuse: call umount(8) directly instead of fusermount if
964 * Clean up init script, make it LSB compliant
966 2007-04-26 Miklos Szeredi <miklos@szeredi.hu>
968 * In multithreaded loop, use a semaphore instead of SIGHUP to wake
969 up the main thread on umount. This is more elegant, and works
970 even if signals are blocked.
972 2007-04-25 Miklos Szeredi <miklos@szeredi.hu>
974 * Improve mounting support in libfuse:
975 - check non-empty mountpoint
976 - only fall back to fusermount when necessary
978 2007-04-23 Miklos Szeredi <miklos@szeredi.hu>
980 * Don't chdir to "/" in foreground mode, it causes more trouble
983 2007-04-18 Miklos Szeredi <miklos@szeredi.hu>
985 * Replace utils/mount.fuse "sh" script with a "C" program
987 2007-04-15 Miklos Szeredi <miklos@szeredi.hu>
989 * Add -lulockmgr to compilation comment in fusexmp_fh.c
991 2007-04-05 Miklos Szeredi <miklos@szeredi.hu>
993 * Check for iconv. Patch by Csaba Henk
995 * Add direct umounting
997 * Use "fusectl" as the device for the fusectl filesystem. Debian
998 Bug#417945. Reported by Laurent Bonnaud
1000 2007-04-01 Csaba Henk <csaba.henk@creo.hu>
1002 * Fix some FreeBSD related macros.
1004 2007-03-30 Miklos Szeredi <miklos@szeredi.hu>
1006 * Add support for direct mounting by libfuse. Fall back on
1007 calling fusermount if it doesn't work
1009 2007-03-14 Miklos Szeredi <miklos@szeredi.hu>
1011 * Released 2.7.0-pre1
1013 2007-03-05 Miklos Szeredi <miklos@szeredi.hu>
1015 * Correctly handle O_APPEND in direct IO mode. Reported by Greg
1018 * mount.fuse should use /bin/bash. Debian Bug#413403. Reported
1019 by Thomas Weinbrenner
1021 2007-02-26 Miklos Szeredi <miklos@szeredi.hu>
1023 * Fix detection of installed fuse in init script. Reported and
1024 fix suggested by Davide Canova
1026 2007-02-05 Miklos Szeredi <miklos@szeredi.hu>
1028 * Fix 2.6.9 RHEL kernels, which have compatibility mutex.h, but
1029 don't define mutex_destroy(), bummer. Patch from Phil Schwan
1031 2007-02-04 Miklos Szeredi <miklos@szeredi.hu>
1033 * Compile fuseblk for kernels which don't have an option to turn
1034 off the block layer (CONFIG_BLOCK). Reported by Szakacsits
1037 2007-02-03 Miklos Szeredi <miklos@szeredi.hu>
1039 * Add filesystem stacking support to high level API. Filesystem
1040 modules can be built into libfuse or loaded from shared object
1043 * Add 'subdir' and 'iconv' built in modules
1045 * lib/fuse.c: Fix locking for the reply code in create and open
1047 2007-02-02 Miklos Szeredi <miklos@szeredi.hu>
1049 * kernel: make it compile on "strange" kernels which have emulated
1050 mutexes via <linux/mutex.h> but no i_mutex. Reported by Tomasz
1053 2007-01-28 Miklos Szeredi <miklos@szeredi.hu>
1055 * kernel: fix BUG in control filesystem if it is umounted and
1056 mounted again, while some fuse filesystems are present.
1057 Bugreport from Florent Mertens
1059 * kernel: sync with mainline, support 2.6.20
1061 2007-01-22 Miklos Szeredi <miklos@szeredi.hu>
1063 * lib/Makefile.am: actually link libfuse against libfuse_libs
1065 2007-01-19 Miklos Szeredi <miklos@szeredi.hu>
1067 * Build fix for 2.6.16 vanila and 2.6.15 FC5 kernels. Patch from
1070 2007-01-18 Miklos Szeredi <miklos@szeredi.hu>
1072 * Fix abort in fuse_new() compatibility API for opts == NULL case.
1073 Novell bugzilla #233870. Patch from Takashi Iwai.
1075 2007-01-13 Miklos Szeredi <miklos@szeredi.hu>
1077 * Fix option parsing in mount.fuse. Patch from Jens M. Noedler
1079 2007-01-02 Miklos Szeredi <miklos@szeredi.hu>
1081 * Fix unaligned access in file desctriptor passing in libfuse,
1082 fusermount and ulockmgr. Debian bug ID: 404904. Reported and
1083 tested by Sebastian Fontius
1085 2006-12-16 Miklos Szeredi <miklos@szeredi.hu>
1087 * kernel: don't keep unreferenced inodes in the icache.
1089 2006-12-15 Miklos Szeredi <miklos@szeredi.hu>
1091 * fusermount: Fix detection of fuseblk. Reported by Szakacsits
1094 * lib: Fix use after free in fuse_flush(). Reported by Ron
1097 2006-12-10 Miklos Szeredi <miklos@szeredi.hu>
1099 * mount.fuse: add "setuid=USER" option which does a "su - USER"
1102 * fusermount: use "/bin/mount -f" to add entry to /etc/mtab, and
1103 "/bin/umount" to remove entry from /etc/mtab. This gets rid of
1104 the ugly code dealing with mtab, as well as a possible race
1105 between fusermount and mount trying to modify /etc/mtab at the
1108 * Fix "buffer size too small: 4" warning for users of the
1109 fuse_loop_mt_proc() function.
1111 2006-12-04 Miklos Szeredi <miklos@szeredi.hu>
1113 * Fix warnings with gcc-4.1 on 64bit archs. Report from
1116 * Add extra warning options, and fix resulting warnings
1118 * Really fix fuse_teardown problem
1120 2006-12-02 Miklos Szeredi <miklos@szeredi.hu>
1122 * Add -lrt to fuse.pc (if needed) to fix static linking against
1123 libfuse. Reported by Szakacsits Szabolcs
1125 2006-12-01 Miklos Szeredi <miklos@szeredi.hu>
1129 2006-11-30 Miklos Szeredi <miklos@szeredi.hu>
1131 * Fix API version 21 and 22 compatibility for fuse_teardown.
1134 2006-11-29 Miklos Szeredi <miklos@szeredi.hu>
1136 * fusermount: Print a more helpful message in case the kernel
1137 doesn't support the 'fuseblk' filesystem type. This has been
1138 biting ntfs-3g users. Reported by Yura Pakhuchiy
1140 * kernel: fix build problem for "make -C ...". Reported by
1143 2006-11-19 Miklos Szeredi <miklos@szeredi.hu>
1145 * Fix bug in certain error paths of lookup routines. The request
1146 object was reused for sending FORGET, which is illegal. This bug
1147 could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
1148 silently corrupt memory in earlier versions. Report and test
1151 2006-11-11 Miklos Szeredi <miklos@szeredi.hu>
1153 * Print an error if an incompatible kernel interface version is
1154 detected in INIT. This will only show if filesystem is started
1157 * Fix order of fuse_destroy()/fuse_unmount() in error cleanup of
1158 fuse_setup_common(). Reported by Szakacsits Szabolcs
1160 2006-11-06 Miklos Szeredi <miklos@szeredi.hu>
1162 * Fix recursive locking in fuse_create(). Thanks to Takuya
1163 Ishibashi for the bug report
1165 2006-10-28 Miklos Szeredi <miklos@szeredi.hu>
1167 * Fix automake problem. Patch from Nix
1169 2006-10-26 Miklos Szeredi <miklos@szeredi.hu>
1171 * Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not
1172 always available on embedded systems. Patch from Paul Smith
1174 * Fix util/Makefile.am, so that failure to run update-rc.d or
1175 device creation doesn't cause make to fail. Reported by Paul
1178 2006-10-21 Miklos Szeredi <miklos@szeredi.hu>
1182 2006-10-18 Miklos Szeredi <miklos@szeredi.hu>
1184 * fusermount: don't try to create a lock file if /etc/mtab is a
1185 symlink. Report and patch from Alexei Sheplyakov (debian bug
1188 2006-10-17 Miklos Szeredi <miklos@szeredi.hu>
1190 * Minor changes, sync with mainline tree
1192 2006-10-16 Miklos Szeredi <miklos@szeredi.hu>
1194 * Released 2.6.0-rc3
1196 2006-10-15 Miklos Szeredi <miklos@szeredi.hu>
1200 2006-10-13 Miklos Szeredi <miklos@szeredi.hu>
1202 * kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
1203 Report from David Shaw
1205 * lib: Fix lost error on renaming a file. Report from David Shaw
1207 * lib: Fix lost error on hiding open files (renaming to
1210 * kernel: Fix a rare hang on SMP/32bit on heavy filesystem
1211 activity. The cause of the bug was that some calls to
1212 i_size_write() were not protected by a lock, and hence
1213 i_size_seqcount could become corrupted. This caused subsequent
1214 calls to i_size_read() to spin forever. This is a long standing
1215 bug was probably introduced in version 2.2, and thought to be
1216 related to NFS exporting (it's not). It was reported by various
1217 people, but Dana Henriksen has finally helped me to track it down,
1218 so big thanks to him
1220 * kernel: Protect against truncation of a swapfile
1222 2006-10-10 Miklos Szeredi <miklos@szeredi.hu>
1224 * kernel: Check for signature of super_operations->umount_begin().
1225 Ubuntu kernel 2.6.17 seems to use the new signature found in
1226 2.6.18. Thanks to Florent Mertens for the report
1228 2006-10-08 Miklos Szeredi <miklos@szeredi.hu>
1230 * Make sure inode numers wrap around at 2^32. This is needed on
1231 dual 64bit/32bit architectures, because 32bit applications using
1232 the non-largefile interface would otherwise break (EOVERFLOW error
1233 would be returned by the stat() system call family)
1235 * ulockmgr: handle the case, when a locking operation fails
1236 because no more file desctriptors are available in
1237 ulockmgr_server. Also work around a Linux kernel bug (known to
1238 exist for all Linux kernel versions <= 2.6.18) which may cause
1239 sent file descriptors to be lost in the above case
1241 * ulockmgr: optimize file descriptor use
1243 * restore needed cpp flags to util/Makefile.am
1245 * Install udev rules as 99-fuse.rules instead of 60-fuse.rules
1247 * Minor clean up of udev rules
1249 * Add a synchronous DESTROY message to kernel interface. This is
1250 invoked from umount, when the final instance of the filesystem is
1251 released. It is only sent for filesystems mounted with the
1252 'blkdev' option for security reasons.
1254 * If the DESTROY message is received, call the filesystem's
1255 ->destroy() method. In this case it's not called from session
1256 destruction as it would be otherwise.
1258 2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
1260 * Released 2.6.0-rc2
1262 2006-10-01 Miklos Szeredi <miklos@szeredi.hu>
1264 * Add support for FLUSH+RELEASE operation for FreeBSD. Original
1267 * Add init script to insert fuse module and mount the control
1268 filesystem. The script is installed as /etc/init.d/fuse and on
1269 debian based systems (where update-rc.d is available) symlinks
1270 from /etc/rc*.d/ are also installed.
1272 * Include '#define FUSE_USE_VERSION=XX' into examples so they
1273 become more self contained.
1275 2006-09-30 Miklos Szeredi <miklos@szeredi.hu>
1279 * Move lock_owner from a separate argument into fuse_file_info
1281 * Add a flag to fuse_file_info indicating (1) a highlevel lock
1282 operation (unlock all) was initiated by a flush, (2) a lowlevel
1283 release operation should perform a flush as well.
1285 * fusermount: revert modprobe change (2006-08-18) since it
1286 doesn't work reliably with udev
1288 * Add support for block device backed filesystems. This mode is
1289 selected with the 'blkdev' option, which is privileged.
1291 * Add support for the bmap (FIBMAP ioctl) operation on block
1292 device backed filesystems. This allows swapon and lilo to work on
1297 * Drop support for kernels earlier than 2.6.9. Kernel module from
1298 previous (2.5.x) release can be used with library from this
1301 * In fuse_dentry_revalidate() use dget_parent() instead of
1302 dereferencing d_parent, since there's no protection against parent
1303 changing and going away
1305 * Protect nlookup from concurrent updates
1307 * In lookup if a directory alias exists but is unused,
1308 then get rid of it, otherwise return -EBUSY.
1310 * In mkdir if a directory alias exists, return success, but leave
1311 dentry negative. In reality this could happen if a remote rename
1312 immediately followed the mkdir.
1314 * Don't BUG in fuse_iget() if multiple retries are needed to get a
1315 good inode. This could happen if several lookups are racing for
1318 2006-09-29 Miklos Szeredi <miklos@szeredi.hu>
1320 * Fix compilation on 2.6.9. Report from Troy Ayers
1322 2006-09-27 Miklos Szeredi <miklos@szeredi.hu>
1324 * Fix Oops in fuse_readpages(). Reported by David Shaw
1326 2006-09-24 Csaba Henk <csaba.henk@creo.hu>
1328 * Add support for nanosec times on FreeBSD
1330 * Fix FreeBSD compatibility issues
1332 2006-09-23 Miklos Szeredi <miklos@szeredi.hu>
1334 * Fix one more compatibility bug. Thanks to Ricardo Correia
1336 * Fix utimens compilation with uClibc. Patch from Jamie Guinan
1338 2006-09-22 Miklos Szeredi <miklos@szeredi.hu>
1340 * Fixed several compatibility bugs in low level interface.
1341 Reported by Ricardo Correia
1343 * Add workaround for ARM caching bug
1345 2006-09-16 Miklos Szeredi <miklos@szeredi.hu>
1347 * Rename new utimes() method to more logical utimens()
1349 2006-09-14 Miklos Szeredi <miklos@szeredi.hu>
1351 * Fuse tried to unlink already unlinked hidden files. Bug
1352 reported by Milan Svoboda
1354 2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
1356 * Released 2.6.0-rc1
1358 2006-09-10 Miklos Szeredi <miklos@szeredi.hu>
1360 * kernel: Fix unlock on close for kernels < 2.6.18
1362 * Add ulockmgr library & server. This can be used for handling
1363 file locking requests either directly from libfuse or over a
1364 network, etc. This first version is not optimized and the number
1365 of file descriptors it uses may get out of hand
1367 2006-09-07 Miklos Szeredi <miklos@szeredi.hu>
1369 * lib: Add interrupt support to high level library, which may be
1370 enabled with the 'intr' mount option.
1372 * When an operation is interrupted the thread handling that
1373 operation will receive SIGUSR1 (or other signal specified with the
1374 'intr_signal=N' option). The library installs a no-op signal
1375 handler for this signal, unless there's already a handler
1378 * The filesystem may query interrupt status (regardless of 'intr')
1379 with the fuse_interrupted() function.
1381 * mount.fuse: initialize $HOME if not set. Report from Sven Goldt
1383 2006-09-03 Miklos Szeredi <miklos@szeredi.hu>
1385 * lib: Multithreaded loop now allows unlimited number of threads.
1386 This is needed for locking operations which may block
1387 indefinitely. Also the kernel now doesn't limit the number of
1388 outstanding requests so the library shouldn't do so either.
1390 2006-09-01 Miklos Szeredi <miklos@szeredi.hu>
1392 * Fix recursive lock bug in interrupt handling
1394 * Add utimes() method to highlevel interface, which supports
1395 setting times with nanosecond resolution
1397 2006-08-18 Miklos Szeredi <miklos@szeredi.hu>
1399 * kernel: fix page leak if fuse_readpages() failed in it's
1400 initialization. Bug found and original patch from Alexander
1403 * For linux kernels >=2.6.18 (2.6.19 if using the fuse module from
1404 the kernel tree) the statfs method will receive the path within
1405 the filesystem on which the stat(v)fs syscall was called
1407 * fusermount: try to modprobe fuse module if invoked by root and
1408 unable to open device. This is needed with udev, since the device
1409 node will be created only when the module is inserted, hence
1410 module autoloading won't work. Reported by Szakacsits Szabolcs
1412 2006-07-30 Miklos Szeredi <miklos@szeredi.hu>
1414 * fusermount: if selinux is active, restore the original file's
1415 security context in unmount_rename(). Redhat bugzilla id 188561.
1416 Patch from Yves Perrenoud
1418 * Add POSIX file locking operation to high level library
1420 * Initialize context for unlink of hidden files on umount. Bug
1421 reported by Tim Stoakes
1423 2006-07-14 Miklos Szeredi <miklos@szeredi.hu>
1425 * Multiple release() calls can race with each other, resulting in
1426 the hidden file being deleted before the last release finishes.
1427 Bug found and patch tested by Mark Huijgen
1429 2006-07-05 Miklos Szeredi <miklos@szeredi.hu>
1431 * fusermount: if /dev/fuse doesn't exist, suggest modprobing fuse;
1432 this makes sense on systems using udev. Reported by Szakacsits
1435 2006-06-29 Miklos Szeredi <miklos@szeredi.hu>
1437 * Released 2.6.0-pre3
1439 2006-06-29 Miklos Szeredi <miklos@szeredi.hu>
1441 * Support in kernel module for file locking and interruption. The
1442 same functionality is available in official kernels >= 2.6.18
1444 2006-06-28 Miklos Szeredi <miklos@szeredi.hu>
1446 * Add POSIX file locking support
1448 * Add request interruption
1450 2006-06-06 Miklos Szeredi <miklos@szeredi.hu>
1452 * Add missing pthread_rwlock_destroy(). Patch from Remy Blank
1454 2006-06-05 Remy Blank <remy.blank@pobox.com>
1456 * lib: canonicalize mount point in fuse_helper_opt_proc() so that
1457 unmounting succeeds even if mount point was relative.
1459 2006-06-04 Csaba Henk <csaba.henk@creo.hu>
1461 * lib: fix emergency umount in helper.c when malloc fails.
1462 (The way it was done would end up in a segfault.)
1464 2006-06-01 Csaba Henk <csaba.henk@creo.hu>
1466 * lib: adjust threading related compiler flags.
1467 Switch to "-pthread" from "-lpthread" as that's the preferred
1468 one on several platforms. Consulted with Terrence Cole and
1471 2006-05-08 Miklos Szeredi <miklos@szeredi.hu>
1473 * lib: search fusermount in installation directory (bindir) as
1476 2006-05-03 Miklos Szeredi <miklos@szeredi.hu>
1478 * lib: fix compilation if CLOCK_MONOTONIC is not defined.
1479 Reported by Christian Magnusson
1481 2006-04-23 Csaba Henk <csaba.henk@creo.hu>
1483 * lib: make FreeBSD mount routine recognize if kernel features
1484 backgrounded init and if it does, run the mount util in foreground
1485 (similarly to Linux)
1487 2006-04-21 Miklos Szeredi <miklos@szeredi.hu>
1489 * kernel: fix fput deadlock fix, the lockless solution could lead
1490 to "VFS: busy inodes after umount..."
1492 * kernel: fix race between checking and setting file->private_data
1493 for the device. Found by Al Viro
1495 2006-04-11 Miklos Szeredi <miklos@szeredi.hu>
1497 * kernel: remove request pool, instead allocate requests on
1498 demand. Account the number of background requests, and if they go
1499 over a limit, block the allocation of new requests.
1501 * kernel: fix deadlock if backgrounded request holds the last
1502 reference to the super block
1504 * kernel: don't use fuse_reset_request() during direct I/O
1506 2006-04-06 Csaba Henk <csaba.henk@creo.hu>
1508 * lib: Let FreeBSD mount option parsing routine recognize "no"
1509 prefixes for FUSE specific options as well
1511 2006-04-01 Miklos Szeredi <miklos@szeredi.hu>
1513 * lib: Add missing rwlock initialization. Patch by Ryan Bradetich
1515 2006-03-17 Miklos Szeredi <miklos@szeredi.hu>
1519 * fuse_main(), fuse_setup() and fuse_new() have an additionl
1522 * fuse_mount() returns a 'struct fuse_chan' pointer instead of a
1525 * fuse_unmount() receives a 'struct fuse_chan' pointer. It
1526 destroys the given channel
1528 * fuse_teardown() no longer has a file descriptor parameter
1530 * new exported functions: fuse_session_remove_chan(),
1531 fuse_get_session(), fuse_daemonize()
1533 * fuse_chan_recv() may now return a new channel which will be used
1536 2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
1538 * Released 2.6.0-pre2
1540 2006-03-16 Miklos Szeredi <miklos@szeredi.hu>
1542 * Don't unmount if already unmounted. This fixes a problem seen
1543 in the following situation: Lazy unmount a busy filesystem; Mount
1544 a new one in top; When the first finally unmounts, the second also
1545 unmounts. Reported by Franco Broi
1547 2006-03-15 Miklos Szeredi <miklos@szeredi.hu>
1549 * lowlevel lib: use indirect function calls instead of a
1550 switch/case construct. Besides increased efficiency it helps
1551 maintainability & readability too. Patch from Florin Malita
1553 2006-03-13 Miklos Szeredi <miklos@szeredi.hu>
1555 * kernel: replace global spinlock with a per-connection spinlock
1557 2006-03-10 Miklos Szeredi <miklos@szeredi.hu>
1559 * Fix source compatibility breakage for fuse_unmount(). Report
1562 2006-03-02 Miklos Szeredi <miklos@szeredi.hu>
1564 * Fix O_ASYNC handling in fuse_dev_release(). From Jeff Dike
1566 2006-03-01 Miklos Szeredi <miklos@szeredi.hu>
1568 * Add O_ASYNC and O_NONBLOCK support to FUSE device. Patch by
1571 * Renamed fuse_chan_receive() to fuse_chan_recv() and changed
1572 interface to return -errno in case of error.
1574 2006-03-01 Csaba Henk <csaba.henk@creo.hu>
1576 * libfuse: pass device file descriptor to fuse_unmount(), rewrite
1577 FreeBSD implementation so that it uses libc (sysctl backed) instead
1578 of an embdedded script (kmem backed). Adjust the control flow of
1579 hello_ll so that device doesn't get closed before unmount attempt.
1581 2006-02-25 Miklos Szeredi <miklos@szeredi.hu>
1583 * Lowlevel lib: return all-zero statvfs data if filesystem doesn't
1584 implement method. This is needed on FreeBSD, and nicer on Linux
1585 too. Highlevel lib already did this. Reported by Csaba Henk
1587 * Fix negative entry handling. There was a bug, that negative
1588 lookups with timeouts (nodeid == 0) returned -EIO.
1590 2006-02-23 Miklos Szeredi <miklos@szeredi.hu>
1592 * Fix race between RELEASE and UNLINK, which might leave
1593 .fuse_hidden* files around
1595 2006-02-21 Miklos Szeredi <miklos@szeredi.hu>
1597 * fusexmp_fh: implement flush() method and call close() on the
1598 open file descriptor. This is needed if used on an NFS
1599 filesystem, which buffers data until file is closed. Franco Broi
1600 spotted the situation when 'cp -p' failed to set the modification
1601 time because of this.
1603 2006-02-20 Miklos Szeredi <miklos@szeredi.hu>
1605 * Released 2.6.0-pre1
1607 2006-02-19 Miklos Szeredi <miklos@szeredi.hu>
1609 * libfuse: fix use-after-free bug in interruptred reply_entry().
1610 Patch from John Muir
1612 * libfuse: fix wrong symbol versioning for fuse_mount. Debian bug
1613 ID: 352631. Found by Stéphane Rosi
1615 2006-02-17 Miklos Szeredi <miklos@szeredi.hu>
1617 * Lowlevel lib: Unify fuse_dirent_size() and fuse_add_dirent()
1618 into a single function fuse_add_direntry(). This cleans up the
1619 interface and makes it possible to do stacking.
1621 2006-02-16 Miklos Szeredi <miklos@szeredi.hu>
1623 * Fix rare race betweeen abort and release caused by failed iget()
1624 in fuse_create_open().
1626 * Add 'ac_attr_timeout' option e.g. for filesystems which do their
1627 own attribute caching.
1629 2006-02-15 Miklos Szeredi <miklos@szeredi.hu>
1631 * Work around FreeBSD runtime linker "feature" which binds an old
1632 version of a symbol to internal references if the symbol has more
1633 than one version. This resulted in infinite recursion in
1634 fuse_lowlevel_new_compat25().
1636 2006-02-10 Csaba Henk <csaba.henk@creo.hu>
1638 * Refine clock_gettime() querying so that linker options
1639 shall be set as it's appropriate for the target platform.
1641 2006-02-09 Miklos Szeredi <miklos@szeredi.hu>
1643 * Fix udev rule syntax. Reported by Nix
1645 2006-02-08 Miklos Szeredi <miklos@szeredi.hu>
1647 * In some cases udev rule seems to be ineffective when installed
1648 as 40-fuse.rules but work as 60-fuse.rules. Reported by John Hunt
1650 2006-02-03 Miklos Szeredi <miklos@szeredi.hu>
1652 * Fix compilation when build directory is different from source
1653 directory. Reported by Frédéric L. W. Meunier
1655 2006-02-02 Miklos Szeredi <miklos@szeredi.hu>
1657 * Fix even bigger bug introduced in fix for request_end() on
1658 2006-01-14. Reported by Gal Rosen
1660 2006-01-30 Miklos Szeredi <miklos@szeredi.hu>
1662 * highlevel-lib: add 'auto_cache' option. This caches file data
1663 based on modification time and size
1665 2006-01-20 Miklos Szeredi <miklos@szeredi.hu>
1667 * Sanitize storage type and help message in mount_bsd.c. Patch
1670 * fuse_opt: add new helper constants FUSE_OPT_KEY_KEEP and
1671 FUSE_OPT_KEY_DISCARD
1673 * Add options 'max_readahead', 'sync_read' and 'async_read'
1675 * Kernel ABI version 7.6:
1677 * Negotiate the 'max_readahead' value and 'async_read' flags with
1678 userspace in the INIT method
1680 * Add connection info to ->init() methods to both lowlevel and
1683 * Fall back to synchronous read() behavior if either library or
1684 userspace filesystem is using the old interface version. This is
1685 needed so non-updated filesystems won't be confused by the
1686 different read() behavior
1688 2006-01-19 Miklos Szeredi <miklos@szeredi.hu>
1690 * lib: if "fsname=" option was given, pass it to fusermount
1692 * fuse_opt: add new fuse_opt_insert_arg() function, which is
1693 needed by filesystems to implement some argument manipulations
1696 * fuse_opt: fix memory leak in handling "--" option
1698 2006-01-18 Miklos Szeredi <miklos@szeredi.hu>
1700 * kernel: fix detection of case when fuse is not configured into
1701 the kernel either as module or built-in
1703 * fuse_opt.h: fix incompatibility with C++ compilers by renaming
1704 'template' structure member to 'templ'. Reported by Takashi Iwai
1706 * fuse.h: fix compatibility bugs. Patch by Yura Pakhuchiy
1708 * kernel: support version 2.6.16 (i_sem -> i_mutex)
1710 2006-01-16 Miklos Szeredi <miklos@szeredi.hu>
1712 * Added (again) asynchronous readpages support
1714 * Each connection now shows up under /sys/fs/fuse/connections
1716 * Connection attributes exported to sysfs: 'waiting' number of
1717 waiting requests; 'abort' abort the connection
1719 * Connection may be aborted through either the sysfs interface or
1720 with 'umount -f mountpoint'
1722 2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
1726 2006-01-14 Miklos Szeredi <miklos@szeredi.hu>
1728 * kernel: fix a couple of bugs
1730 * Order of request_end() and fuse_copy_finish() was wrong.
1731 Posthumous note: Franco Broi managed to exploit this, though it
1732 seemed quite impossible
1734 * request_end() used request pointer after decrementing refcount
1736 * Clearing ->connected or ->mounted connection flags could race
1737 with setting other bitfields not protected with a lock
1739 2006-01-10 Miklos Szeredi <miklos@szeredi.hu>
1741 * kernel: add necessary compile flags for 2.4.X/x86_64.
1742 Report from Sean Ziegeler
1744 2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
1746 * Released 2.5.0-pre2
1748 2006-01-09 Miklos Szeredi <miklos@szeredi.hu>
1750 * Applied patch from Csaba Henk, to update mount_bsd to new
1751 fuse_mount() semantics
1753 * Ignore auto,noauto,... options in mount.fuse. Reported by Frank
1754 Steiner and Don Taber
1756 * fusermount: add 'dirsync' mount option
1758 2006-01-07 Miklos Szeredi <miklos@szeredi.hu>
1760 * Improved help reporting and added version reporting to library
1762 2006-01-06 Miklos Szeredi <miklos@szeredi.hu>
1764 * Change working directory to "/" even if running in the
1765 foreground. Patch from Jonathan Brandmeyer
1767 * Changed lots of functions to use 'struct fuse_args' instead of
1768 separate argc and argv
1770 * Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
1771 fuse_remove_signal_handlers() functions, so that it's now pretty
1772 easy to get all the functionality of fuse_main() with a filesystem
1773 using the lowlevel API.
1775 2006-01-02 Miklos Szeredi <miklos@szeredi.hu>
1777 * mount.fuse: the 'user' option should be ignored. Report and
1778 solution from Mattd.
1780 * mount.fuse: export PATH in the right place. Report and patch
1781 from Hannes Schweizer
1783 2005-12-16 Miklos Szeredi <miklos@szeredi.hu>
1785 * Clean up the option parsing interface slightly, by creating an
1786 "argument list" structure, that contains the argument vector and
1789 2005-12-15 Miklos Szeredi <miklos@szeredi.hu>
1791 * fusermount: check if /mnt/mtab is a symlink and don't modify it
1794 * kernel: simplify request size limiting. INIT only contains
1795 maximum write size, maximum path component size remains fixed at
1796 1024 bytes, and maximum xattr size depends on read buffer.
1798 2005-12-14 Miklos Szeredi <miklos@szeredi.hu>
1800 * Fix readdir() failure on x86_64, of 32bit programs compiled
1801 without largefile support. Bug report and help from Anthony
1804 * If lookup returns invalid mode, return -EIO instead of creating
1807 * Add current output argument vector to option processing
1810 2005-12-12 Miklos Szeredi <miklos@szeredi.hu>
1812 * Fix stale code in ifdef FreeBSD. Patch from Csaba Henk
1814 2005-12-09 Miklos Szeredi <miklos@szeredi.hu>
1816 * Released 2.5.0-pre1
1818 2005-12-09 Miklos Szeredi <miklos@szeredi.hu>
1820 * libfuse: added option parsing interface, defined in
1823 2005-12-07 Miklos Szeredi <miklos@szeredi.hu>
1825 * Return EIO for file operations (read, write, fsync, flush) on
1826 open files whose inode has become "bad". Inodes will be marked
1827 "bad" if their type changes. Bug report by Csaba Henk
1829 2005-12-06 Miklos Szeredi <miklos@szeredi.hu>
1831 * Use bigger request buffer size. write() did not work on archs
1832 with > 4k page size, Bug report by Mark Haney
1836 * Extend INIT reply with data size limits
1838 2005-12-02 Miklos Szeredi <miklos@szeredi.hu>
1840 * Fix memory leak in fuse_read_cmd()/fuse_process_cmd(). Bug
1841 reported by Vincenzo Ciancia
1843 * Handle exit-by-umount in fuse_read_cmd()
1845 2005-11-29 Miklos Szeredi <miklos@szeredi.hu>
1847 * Check if '-msoft-float' option is supported by compiler when
1848 configuring for a 2.4.x kernel. Bug report by Mark Haney
1850 * In multithreaded loop send a TERM signal to the main thread if
1851 one of the other threads exit. Needed on FreeBSD for a clean exit
1852 on umount. Should not cause any harm on Linux either
1854 2005-11-28 Miklos Szeredi <miklos@szeredi.hu>
1856 * Fix bug in 32-bit file handle compatibility
1858 2005-11-27 Miklos Szeredi <miklos@szeredi.hu>
1860 * Block TERM, INT, HUP and QUIT signals in all but the main
1861 thread. According to POSIX it's not specified which thread will
1862 receive these signals.
1866 * Check for directory aliasing on mkdir, not just on lookup
1868 * Check for special node ID values in create+open operation
1870 * Sync with -mm: readv, writev, aio_read and aio_write methods
1871 added to file operations
1873 * Cleanups: lookup code, page offset calculation
1875 * ABI stepped to 7.4, changes:
1877 * frsize member added to fuse_kstatfs structure
1879 * added support for negative entry caching: on lowlevel API if
1880 fuse_entry_param::ino is set to zero in reply to a lookup request,
1881 the kernel will cache the dentry for the specified amount of time.
1883 * libfuse: added 'negative_timeout' option: specifies how much
1884 negative entries should be cached. Default is zero, to be
1885 compatible with prior versions
1887 2005-11-22 Miklos Szeredi <miklos@szeredi.hu>
1889 * Add detection of mainline FUSE code in running kernel
1891 2005-11-21 Miklos Szeredi <miklos@szeredi.hu>
1893 * Don't use async cancelation in multithreaded loop. This makes
1894 it more portable to systems where read() is not async cancel safe.
1895 Report from Andriy Gapon
1897 2005-11-20 Miklos Szeredi <miklos@szeredi.hu>
1899 * Warn if API version 11 compatibility is requested
1901 2005-11-17 Miklos Szeredi <miklos@szeredi.hu>
1903 * More FreeBSD merge
1905 * fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
1906 them, because it corrupts /etc/mtab. Found by Thomas Biege
1909 * libfuse: don't use system() to invoke 'fusermount -u ...'
1910 because it breaks mountpoints with spaces in them into multiple
1913 2005-11-16 Miklos Szeredi <miklos@szeredi.hu>
1915 * Merge library part of FreeBSD port. Patch by Csaba Henk
1917 2005-11-11 Miklos Szeredi <miklos@szeredi.hu>
1919 * Use 64bit type for file handle, so the full range supported by
1920 the kernel interface is available to applications
1922 2005-11-10 Miklos Szeredi <miklos@szeredi.hu>
1924 * Moved mountpoint argument checking from fuse_parse_cmdline() to
1925 fuse_mount() in preparation to FreeBSD merge.
1927 2005-11-08 Miklos Szeredi <miklos@szeredi.hu>
1929 * Remove unneeded close() from fuse_teardown(). Spotted by Csaba
1932 2005-11-07 Miklos Szeredi <miklos@szeredi.hu>
1934 * Make the statfs change backwards compatible.
1936 2005-11-06 Miklos Szeredi <miklos@szeredi.hu>
1938 * Change ->statfs() method to use 'struct statvfs' instead of
1939 'struct statfs'. This makes the API more portable since statvfs()
1940 is defined by POSIX.
1942 2005-10-28 Miklos Szeredi <miklos@szeredi.hu>
1944 * Add fgetattr() method, which currently will only be called after
1945 a successful call to a create() method.
1947 2005-10-26 Miklos Szeredi <miklos@szeredi.hu>
1949 * Change kernel ABI version to 7.3
1951 * Add ACCESS operation. This is called from the access() system
1952 call if 'default_permissions' mount option is not given, and is
1953 not called on kernels 2.4.*
1955 * Add atomic CREATE+OPEN operation. This will only work with
1956 2.6.15 (presumably) or later Linux kernels.
1958 * Add ftruncate() method. This will only work with 2.6.15
1959 (presumably) or later Linux kernels.
1961 * Fix kernel module compile if kernel source and build directories
1962 differ. Report and initial patch by John Eastman
1964 2005-10-18 Miklos Szeredi <miklos@szeredi.hu>
1966 * lib: optimize buffer reallocation in fill_dir.
1968 2005-10-17 Miklos Szeredi <miklos@szeredi.hu>
1972 2005-10-14 Miklos Szeredi <miklos@szeredi.hu>
1974 * libfuse: add debug for write result (by Shaun Jackman) and
1975 warnings for too large read/write result
1977 2005-10-11 Miklos Szeredi <miklos@szeredi.hu>
1979 * Spelling fixes, thanks to Ioannis Barkas
1981 2005-10-10 Miklos Szeredi <miklos@szeredi.hu>
1983 * fuse_common.h: use extern "C". Thanks to Valient Gough for the
1986 2005-10-07 Miklos Szeredi <miklos@szeredi.hu>
1988 * highlevel-lib: init() and destroy() methods didn't have an
1989 initialized fuse_context. Bug reported by Tim Stoakes
1991 2005-10-04 Miklos Szeredi <miklos@szeredi.hu>
1995 2005-10-03 Miklos Szeredi <miklos@szeredi.hu>
1997 * Add documentation to fuse_lowlevel.h
2001 * Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME
2003 * Move fuse_mount() and fuse_unmount() to fuse_common.h
2005 * Change the return type of fuse_reply_none() from int to void.
2007 2005-09-30 Miklos Szeredi <miklos@szeredi.hu>
2009 * kernel: NFS exporting leaked dentries. Bug found and fixed by
2012 2005-09-29 Miklos Szeredi <miklos@szeredi.hu>
2014 * fusermount: fix error message, when unable to open /dev/fuse.
2015 Report by Balázs Pozsár
2017 2005-09-28 Miklos Szeredi <miklos@szeredi.hu>
2019 * UClibc fixes from Christian Magnusson
2021 2005-09-27 Miklos Szeredi <miklos@szeredi.hu>
2023 * Added NAME="%k" to util/udev.rules. Fix by Mattias Wadman.
2025 2005-09-26 Miklos Szeredi <miklos@szeredi.hu>
2027 * Released 2.4.0-rc1
2029 2005-09-26 Miklos Szeredi <miklos@szeredi.hu>
2031 * fusermount: allow user umount in the case when /etc/mtab is a
2032 symlink to /proc/mounts. Reported by Balázs Pozsár.
2034 2005-09-23 Miklos Szeredi <miklos@szeredi.hu>
2036 * Check for special node ID values in lookup and creation
2038 2005-09-22 Miklos Szeredi <miklos@szeredi.hu>
2040 * Slight optimization in returning EINVAL error in case of an open
2043 2005-09-20 Miklos Szeredi <miklos@szeredi.hu>
2045 * Remove '--enable-auto-modprobe' configure flag. Module
2046 auto-loading is now handled by the kernel.
2048 2005-09-15 Miklos Szeredi <miklos@szeredi.hu>
2050 * Install UDEV rule file, so /dev/fuse is created with mode 0666.
2051 Help from Jens M. Noedler.
2053 2005-09-14 Miklos Szeredi <miklos@szeredi.hu>
2055 * Add memory cleanup on thread exit
2057 2005-09-13 Miklos Szeredi <miklos@szeredi.hu>
2059 * Set umask to zero in fusexmp and fusexmp_fh, so that
2060 files/directories are created with the requested mode.
2062 2005-09-12 Miklos Szeredi <miklos@szeredi.hu>
2064 * Don't ignore read error in multithreaded loop
2066 2005-09-08 Miklos Szeredi <miklos@szeredi.hu>
2068 * Released 2.4.0-pre2
2070 2005-09-08 Miklos Szeredi <miklos@szeredi.hu>
2072 * Revert lock and access operations. Postpone these until 2.5.
2074 2005-09-02 Miklos Szeredi <miklos@szeredi.hu>
2076 * Fix compile warning on 2.6.13 and later
2078 * Fix compilation on old kernels
2080 2005-08-19 Miklos Szeredi <miklos@szeredi.hu>
2082 * lib: always refresh directory contents after rewinddir() to
2083 conform to SUS. Bug found by John Muir.
2085 2005-08-15 Miklos Szeredi <miklos@szeredi.hu>
2087 * Released 2.4.0-pre1
2089 2005-08-14 Miklos Szeredi <miklos@szeredi.hu>
2091 * lib: cleaned up (or messed up, depending on your POV) the low
2092 level library API. Hopefully this is close to the final form.
2094 2005-08-05 Miklos Szeredi <miklos@szeredi.hu>
2096 * fusermount: don't allow empty mountpoint argument, which defeats
2097 automatic umounting in fuse_main(). Bugreport by Václav Jůza
2099 2005-08-03 Miklos Szeredi <miklos@szeredi.hu>
2101 * fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
2102 option is used (Paul Alfille).
2104 2005-08-02 Miklos Szeredi <miklos@szeredi.hu>
2106 * highlevel-lib: added mount options "attr_timeout" and
2107 "entry_timeout". These options control the length of time file
2108 attributes and entries (names) are cached. Both default to 1.0
2111 * kernel: correctly handle zero timeout for attributes and entries
2113 2005-08-01 Miklos Szeredi <miklos@szeredi.hu>
2115 * Added missing symbols to versionscript (Joshua J. Berry)
2117 * kernel: implement two flags, open can set: 'direct_io' and
2118 'keep_cache'. These correspond exactly to mount options
2119 'direct_io' and 'kernel_cache', but allow a per-open setting.
2121 * Move 'direct_io' and 'kernel_cache' mount option handling to
2122 userspace. For both mount options, if the option is given, then
2123 the respective open flag is set, otherwise the open flag is left
2124 unmodified (so the filesystem can set it).
2126 * lib (highlevel): make open method optional
2128 2005-07-28 Miklos Szeredi <miklos@szeredi.hu>
2130 * kernel: invalidate attributes for read/readdir/readlink
2133 * kernel: detect newer UML kernels
2135 2005-07-26 Miklos Szeredi <miklos@szeredi.hu>
2137 * Make the installation path of fuse.ko and mount.fuse
2138 configurable through INSTALL_MOD_PATH and MOUNT_FUSE_PATH
2139 environment variables. Requirement and help from Csaba Henk.
2141 2005-07-22 Miklos Szeredi <miklos@szeredi.hu>
2143 * Fix bug, that causes filesystem requests to hang when unique
2144 request counter becomes negative. This happens after
2145 2,147,483,648 operations, so most people won't care. Thanks to
2146 Franco Broi for the report and testing.
2148 2005-07-21 Miklos Szeredi <miklos@szeredi.hu>
2150 * Don't change mtime/ctime/atime to local time on read/write.
2151 Bug reported by Ben Grimm
2153 * Install fuse_common.h and fuse_lowlevel.h. Report by Christian
2156 * fusermount: use getopt_long() for option parsing. It allows the
2157 use of '--' to stop argument scanning, so fusermount can now
2158 operate on directories whose names begin with a '-'. Patch by
2161 2005-07-15 Miklos Szeredi <miklos@szeredi.hu>
2163 * fusermount: add '-v', '--version' and '--help' options
2165 * add inode based API
2167 2005-07-12 Miklos Szeredi <miklos@szeredi.hu>
2169 * lib: don't block signals in worker threads. Problem noticed by
2172 2005-07-07 Miklos Szeredi <miklos@szeredi.hu>
2174 * lib: don't allow both 'allow_other' and 'allow_root' options to
2177 2005-07-06 Miklos Szeredi <miklos@szeredi.hu>
2179 * fusermount: check if mountpoint is empty (only '.' and '..' for
2180 directories, and size = 0 for regular files). If "nonempty"
2181 option is given, omit this check. This is useful, so users don't
2182 accidentally hide data (e.g. from backup programs). Thanks to
2183 Frank van Maarseveen for pointing this out.
2185 * kernel: check if mandatory mount options ('fd', 'rootmode',
2186 'user_id', 'group_id') are all given
2188 * lib: simplify 'readdir_ino' handling
2190 * lib: add mount options 'umask=M', 'uid=N', 'gid=N'
2192 2005-07-03 Miklos Szeredi <miklos@szeredi.hu>
2194 * kernel: clean up 'direct_io' code
2196 2005-06-28 Miklos Szeredi <miklos@szeredi.hu>
2198 * Add 'mount.fuse' written by Petr Klima
2200 * '/dev/fuse' is created by 'make install' if does not yet exist
2202 2005-06-20 Miklos Szeredi <miklos@szeredi.hu>
2204 * Fix UCLIBC compile error. Patch by Christian Magnusson
2206 2005-06-08 Miklos Szeredi <miklos@szeredi.hu>
2208 * Enable the auto-loading of the module via access to the
2209 corresponding device file. Patch by Takashi Iwai.
2211 * Allow mounting a regular file (over a regular file) for
2214 * Do not create temporary device file. Require "/dev/fuse" to
2215 exist, and be readable/writable by the mounting user.
2217 2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
2221 2005-06-02 Miklos Szeredi <miklos@szeredi.hu>
2223 * Fix serious information leak: if the filesystem returns a short
2224 byte count to a read request, and there are non-zero number of
2225 pages which are not filled at all, these pages will not be zeroed.
2226 Hence the user can read out previous memory contents. Found by
2229 2005-05-27 Miklos Szeredi <miklos@szeredi.hu>
2231 * Add "readdir_ino" mount option, which tries to fill in the d_ino
2232 field in struct dirent. This mount option is ignored if "use_ino"
2233 is used. It helps some programs (e.g. 'pwd' used over NFS from a
2234 non-Linux OS). Patch by David Shaw.
2236 2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
2240 2005-05-12 Miklos Szeredi <miklos@szeredi.hu>
2242 * File save in krusader and other editors doesn't work with sshfs,
2243 because open() is interrupted by a periodic signal, and open()
2244 restarts forever, without any progress. This could just be fixed
2245 in open(), but the problem is more generic: if signals are
2246 received more often than the filesystem can get the request to
2247 userspace, it will never finish. This is probably only a
2248 theoretical problem, nevertheless I'm removing the possibility to
2249 interrupt requests with anything other than SIGKILL, even before
2250 being sent to userspace. Bugreport by Eduard Czimbalmos.
2252 2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
2254 * libfuse: add "tree_lock" rwlock, that is locked for write in
2255 rename, unlink and rmdir, and locked for read in all other
2256 operations. This should fix the rename/release race reported by
2257 Valient Gough and others. The solution is very coarse, a finer
2258 grained locking scheme could be implemented, but it would be much
2259 more complex. Let's see whether this is good enough.
2261 2005-05-09 Miklos Szeredi <miklos@szeredi.hu>
2265 2005-05-08 Miklos Szeredi <miklos@szeredi.hu>
2267 * Better fix for out of order FORGET messages. Now the
2268 LOOKUP/FORGET messages are balanced exactly (one FORGET can
2269 balance many lookups), so the order no longer matters. This
2270 changes the kernel ABI slightly, but the library remains backward
2273 2005-05-06 Miklos Szeredi <miklos@szeredi.hu>
2275 * Fix abort for out of order FORGET messages. Again. Spotted by
2276 Franco Broi again. Sorry :)
2278 2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
2282 2005-04-29 Miklos Szeredi <miklos@szeredi.hu>
2284 * Make fusermount work with fuse kernel modules not yet supporting
2285 the "group_id" option (added for the purpose of stricter
2286 permission checking).
2288 2005-04-28 Miklos Szeredi <miklos@szeredi.hu>
2290 * Check for hard-linked directories in lookup. This could cause
2291 problems in the VFS, which assumes that such objects never exist.
2293 * Make checking of permission for other users more strict. Now
2294 the same privilege is required for the mount owner as for ptrace
2295 on the process performing the filesystem operation.
2297 2005-04-23 Miklos Szeredi <miklos@szeredi.hu>
2301 2005-04-22 Miklos Szeredi <miklos@szeredi.hu>
2303 * Add -msoft-float to kernel module compile flags for 2.4.X. This
2304 is needed on certain architectures. Report from Chris Kirby
2306 * Fix buggy behavior of open(..., O_CREAT|O_EXCL) if interrupted.
2307 Reported by David Shaw
2309 * Remove "allow_root" option from kernel module, and implement
2310 it's functionality in the library
2312 * Fix Oops caused by premature release of fuse_conn. Clean up
2313 related code, to be more readable
2315 * Sendfile should not use page cache if "direct_io" mount option
2318 2005-04-08 Miklos Szeredi <miklos@szeredi.hu>
2320 * Fix Oops in case of nfs export. Spotted by David Shaw
2322 * Fix another Oops in case of write over nfs with direct_io turned
2323 on. Again spotted by David Shaw
2325 2005-04-07 Miklos Szeredi <miklos@szeredi.hu>
2329 2005-04-07 Miklos Szeredi <miklos@szeredi.hu>
2331 * lib: finalized new readdir() interface, which now supersedes the
2334 2005-04-03 Miklos Szeredi <miklos@szeredi.hu>
2338 2005-04-03 Miklos Szeredi <miklos@szeredi.hu>
2340 * Implement backward compatibility with version 5 kernel ABI
2342 2005-04-01 Miklos Szeredi <miklos@szeredi.hu>
2346 2005-04-01 Miklos Szeredi <miklos@szeredi.hu>
2348 * kernel: fix dirent offset handling
2350 * lib: add readdir and releasedir methods
2352 * lib: use fh field of fuse_file_info in opendir, readdir,
2353 releasedir and fsyncdir methods
2355 * lib: check kernel API version and bail out of it's old. This
2356 will be properly fixed in the next release
2358 2005-03-31 Miklos Szeredi <miklos@szeredi.hu>
2362 2005-03-31 Miklos Szeredi <miklos@szeredi.hu>
2364 * kernel API: add padding to structures, so 64bit and 32bit
2365 compiler will return the same size
2367 * kernel API: add offset field to fuse_dirent. This will allow
2368 more sophisticated readdir interface for userspace
2370 * kernel API: change major number to 6
2372 * kernel: fix warnings on 64bit archs
2374 * kernel: in case of API version mismatch, return ECONNREFUSED
2376 2005-03-24 Miklos Szeredi <miklos@szeredi.hu>
2378 * kernel: trivial cleanups
2380 2005-03-21 Miklos Szeredi <miklos@szeredi.hu>
2382 * Add fsyncdir() operation
2384 2005-03-19 Miklos Szeredi <miklos@szeredi.hu>
2386 * kernel: add locking to background list (fixes previous fix)
2388 2005-03-18 Miklos Szeredi <miklos@szeredi.hu>
2390 * kernel: fix bug which could cause leave busy inodes after
2393 2005-03-08 Miklos Szeredi <miklos@szeredi.hu>
2395 * examples: add -lpthread to link flags to work around valgrind
2398 * lib: don't exit threads, so cancelation doesn't cause segfault
2400 2005-03-04 Miklos Szeredi <miklos@szeredi.hu>
2402 * kernel: fix nasty bug which could cause an Oops under certain
2403 situations. Found by Magnus Johansson
2405 2005-02-28 Miklos Szeredi <miklos@szeredi.hu>
2407 * libfuse: added opendir() method. This can be used in case
2408 permission checking in getdir() is too late. Thanks to Usarin
2409 Heininga for pointing out this deficiency
2411 * libfuse: added init() and destroy() methods to fuse_operations
2413 * kernel: llseek() method for files and directories made explicit
2415 * kernel: fixed inode leak in NFS export in case of nodeid
2418 2005-02-15 Miklos Szeredi <miklos@szeredi.hu>
2420 * libfuse: clean up some unitialized memory found with valgrind
2422 * Add -lpthread to Libs in fuse.pc. Valgrind seems to need an
2423 explicitly linked libpthread for applications
2425 2005-02-10 Miklos Szeredi <miklos@szeredi.hu>
2427 * fusermount: set umask, otherwise /etc/mtab will have
2428 unpredictable permission. Spotted by Jindrich Kolorenc
2430 * fusermount: set owner and group of /etc/mtab to original values
2433 * libfuse: add 'use_ino' option to help. Patch by Valient Gough
2435 2005-02-07 Miklos Szeredi <miklos@szeredi.hu>
2437 * Cleaned up directory reading (temporary file is not used)
2439 2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
2443 2005-02-02 Miklos Szeredi <miklos@szeredi.hu>
2445 * Fix possible race when operation is interrupted
2447 2005-01-28 Miklos Szeredi <miklos@szeredi.hu>
2449 * Fix compilation on 2.6.7
2451 2005-01-26 Miklos Szeredi <miklos@szeredi.hu>
2455 2005-01-26 Miklos Szeredi <miklos@szeredi.hu>
2457 * Fix bug in link() operation which caused the wrong path to be
2458 passed as the first argument. Found by Anton Altaparmakov
2460 2005-01-21 Miklos Szeredi <miklos@szeredi.hu>
2462 * LIB: fix double reply in readdir operation
2464 * fusermount: fix uid checking bug. Patch by Adam Connell
2466 * KERNEL: fix compile on various RedHat patched 2.4 kernels.
2467 Patch by Keshava Gowda
2469 2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
2471 * KERNEL: provide correct llseek semantics for fuse device (fixes
2472 a bug on Progeny 2.4.20 kernel). Reported by Valient Gough
2474 2005-01-20 Miklos Szeredi <miklos@szeredi.hu>
2476 * Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)
2478 2005-01-18 Miklos Szeredi <miklos@szeredi.hu>
2480 * KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
2481 and RELEASEDIR. This ends the ugly hack of passing a file
2482 descriptor to the kernel, and actually makes the code simpler.
2484 2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
2488 2005-01-17 Miklos Szeredi <miklos@szeredi.hu>
2490 * fusermount: remove capability setting, which was the cause of
2491 problems for some users. It seems that FS related capabilities
2492 are removed by setfsuid(), so this isn't even needed.
2494 2005-01-15 Miklos Szeredi <miklos@szeredi.hu>
2496 * fix compilation on 2.4 kernels (reported by Valient Gough)
2498 * fix failure to unmount bug (found by David Shaw)
2500 * fusermount: improve parsing of /etc/fuse.conf
2502 2005-01-13 Miklos Szeredi <miklos@szeredi.hu>
2504 * Remove 'mount_max' and 'user_allow_other' module options. These
2505 are now checked by fusermount, and can be set in /etc/fuse.conf
2507 * KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)
2509 2005-01-11 Miklos Szeredi <miklos@szeredi.hu>
2511 * KERNEL: fix possible inode allocation problem, where
2512 sizeof(struct inode) is not aligned (found by Mike Waychison)
2514 * KERNEL: use new follow_link/put_link methods
2516 * KERNEL: cosmetic fixes
2518 2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
2522 2005-01-10 Miklos Szeredi <miklos@szeredi.hu>
2524 * Add missing code that was accidently left out
2526 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2530 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2532 * Change "uid" mount option to "user_id" to avoid confusion with a
2533 mount option "uid" commonly used by many filesystems
2535 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2539 2005-01-09 Miklos Szeredi <miklos@szeredi.hu>
2541 * If FUSE is configured in the kernel, don't build it by default
2543 2005-01-07 Miklos Szeredi <miklos@szeredi.hu>
2545 * Compile fix by Christian Magnusson
2547 2005-01-05 Miklos Szeredi <miklos@szeredi.hu>
2549 * Fix compilation for 2.6.{0-5} kernels
2551 2005-01-04 Miklos Szeredi <miklos@szeredi.hu>
2553 * KERNEL: if request is interrupted, still keep reference to used
2554 inode(s) and file, so that FORGET and RELEASE are not sent until
2555 userspace finishes the request.
2557 * remove /{sys,proc}/fs/fuse/version, and instead add an INIT
2558 request with the same information, which is more flexible,
2559 simpler, works on embedded systems.
2561 2004-12-16 Miklos Szeredi <miklos@szeredi.hu>
2563 * KERNEL ABI: update interface to make it independent of type
2564 sizes. This will help on 64 bit architectures which can run
2565 legacy 32 bit applications.
2567 * KERNEL ABI: add "len" field to request headers. This will allow
2568 sending/receiving requests in multiple chunks.
2570 * KERNEL: handle file type change more intelligently
2572 * LIB: "-o debug" option should disable backgrounding (fix by
2573 Fabien Reygrobellet)
2575 2004-12-13 Miklos Szeredi <miklos@szeredi.hu>
2577 * KERNEL: invalidate dentry/attributes if interrupted request
2578 could leave filesystem in an unknown state.
2580 2004-12-12 Miklos Szeredi <miklos@szeredi.hu>
2582 * KERNEL: lots of cleanups related to avoiding possible deadlocks.
2583 These will cause some regressions, but stability is considered
2584 more important. If any of these features turns out to be
2585 important, it can be readded with the deadlock problems addressed.
2587 * Make all requests interruptible (only with SIGKILL currently).
2588 This can be used to break any deadlock produced by the userspace
2589 filesystem accessing it's own exported files. The RELEASE request
2590 is special, because if it's interrupted before sending it to
2591 userspace it is still sent, but the reply is not awaited.
2593 * If request is interrupted before being sent to userspace, and if
2594 it hasn't yet got any side effects, it is always restarted,
2595 regardless of the SA_RESTART flag. This makes these interruptions
2596 transparent to the process.
2598 * Remove shared-writable mmap support, which was prone to an
2599 out-of-memory deadlock situation
2601 * Remove INVALIDATE userspace initiated request
2603 * Make readpages() synchronous. Asynchronous requests are
2604 deadlock prone, since they cannot be interrupted.
2606 * Add readv/writev support to fuse device operations
2608 * Remove some printks, which userspace FS can use for a DoS
2611 * Remove 'large_read' mount option from 2.6 in kernel, check it in
2614 * LIB: improve compatibility with a fuse.h header installed in
2615 ${prefix}/include which in turn includes the real header.
2617 * LIB: improve compatibility by defining fuse_main() (which is now
2618 not used), so old configure scripts find it.
2620 2004-12-10 Miklos Szeredi <miklos@szeredi.hu>
2622 * When mounting on a subdirectory of / don't duplicate slashes at
2623 the beggining of path (spotted by David Shaw)
2625 2004-12-09 Miklos Szeredi <miklos@szeredi.hu>
2627 * Fix bug causing garbage in mount options (spotted by David Shaw)
2629 2004-12-07 Miklos Szeredi <miklos@szeredi.hu>
2631 * Add 'writepage' flag to 'fuse_file_info'.
2633 * More comments in fuse.h
2635 * Get rid of double underscores
2637 2004-12-04 Miklos Szeredi <miklos@szeredi.hu>
2639 * Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config
2641 * helper.c: add -ho option, which only displays the options not
2642 the usage header. This can be used by filesystems which have
2645 2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
2647 * Add source compatibility to 2.1 and 1.1 APIs. To select betwen
2648 versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
2649 including the fuse header
2651 * Add binary compatibility to 2.1 version of library with symbol
2654 2004-12-03 Miklos Szeredi <miklos@szeredi.hu>
2658 2004-12-01 Miklos Szeredi <miklos@szeredi.hu>
2660 * kernel: clean up writing functions
2662 * kernel: no allocation on write in direct_io mode
2664 * move linux/fuse.h to fuse_kernel.h
2666 2004-11-30 Miklos Szeredi <miklos@szeredi.hu>
2668 * kernel: clean up reading functions
2670 2004-11-29 Miklos Szeredi <miklos@szeredi.hu>
2672 * kernel: make readpage() uninterruptible
2674 * kernel: check readonly filesystem flag in fuse_permission
2676 * lib: don't die if version file not found and new style device
2679 * lib: add '-r' option, which is short for '-o ro'
2681 * fusermount: simplify device opening
2683 * kernel: when direct_io is turend on, copy data directly to
2684 destination without itermediate buffer. More efficient and safer,
2685 since no allocation is done.
2687 * fusermount: fix warning if fuse module is not loaded
2689 * kernel: use /dev/fuse on 2.4 too
2691 2004-11-26 Miklos Szeredi <miklos@szeredi.hu>
2693 * libfuse API change: open, read, write, flush, fsync and release
2694 are passed a 'struct fuse_file_info' pointer containing the open
2695 flags (open and release), and the file handle. Verion changed to
2698 2004-11-23 Miklos Szeredi <miklos@szeredi.hu>
2700 * More cleanups in the kernel
2702 * The 10,229 charater device number has been assigned for FUSE
2704 * Version file checking fix (reported by Christian Magnusson)
2706 * fusermount: opening the fuse device now doesn't need /sys.
2708 * Optimize reading by controlling the maximum readahead based on
2709 the 'max_read' mount option
2711 * fixes for UCLIBC (Christian Magnusson)
2713 2004-11-19 Miklos Szeredi <miklos@szeredi.hu>
2715 * Cleaned up kernel in preparation for merge into mainline:
2717 * Use /sys/fs/fuse/version instead of /proc/fs/fuse/version
2719 * Use real device (/dev/fuse) instead of /proc/fs/fuse/dev
2721 * __user annotations for sparse
2723 * allocate individual pages instead of kmalloc in fuse_readdir,
2724 fuse_read and fuse_write.
2726 * Fix NFS export in case "use_ino" mount option is given
2728 * Make libfuse and fusermount compatible with future versions
2730 * fusermount: properly add mount options to /etc/mtab
2732 2004-11-15 Miklos Szeredi <miklos@szeredi.hu>
2734 * fusermount: do not resolve last component of mountpoint on if it
2735 is '.' or '..'. This new path resolvation is now done on mount as
2736 well as unmount. This enables relative paths to work on unmount.
2738 * fusermount: parse common mount options like "ro", "rw", etc...
2740 * Allow module params to be changed through sysfs
2742 2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
2746 2004-11-14 Miklos Szeredi <miklos@szeredi.hu>
2748 * Fix bug in fuse_readpages() causing Oops in certain situations.
2749 Bug found by Vincenzo Ciancia.
2751 * Fix compilation with kernels versions > 2.6.9.
2753 2004-11-11 Miklos Szeredi <miklos@szeredi.hu>
2755 * Check kernel interface version in fusermount to prevent
2756 strangeness in case of mismatch.
2758 * No need to allocate fuse_conn until actual mount happens
2760 * Fix potential race between umount and fuse_invalidate
2762 * Check superblock of proc file in addition to inode number
2764 * Fix race between request_send_noreply() and fuse_dev_release()
2766 2004-11-10 Miklos Szeredi <miklos@szeredi.hu>
2768 * Separate configure for the kernel directory
2770 * Don't allow write to return more than 'count'
2772 * Extend kernel interface for future use
2774 2004-11-09 Miklos Szeredi <miklos@szeredi.hu>
2776 * Fix 'makeconf.sh' to use autoreconf if available
2778 2004-11-08 Miklos Szeredi <miklos@szeredi.hu>
2780 * Add ino argument to 'fuse_dirfil_t'. NOTE: This breaks source
2781 compatibility with earlier versions. To compile earier versions
2782 just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
2783 Do not use the "use_ino" mount flag with filesystems compiled with
2786 * Add pkg-config support. To compile a FUSE based filesystem you
2787 can do "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
2788 or similar. Note, that the PKG_CONFIG_PATH environment variable
2789 usually needs to be set to "/usr/local/lib/pkgconfig".
2791 * fuse.h is now installed in ${prefix}/include/fuse/
2793 2004-11-02 Miklos Szeredi <miklos@szeredi.hu>
2795 * Added "use_ino" mount option. This enables the filesystems to
2796 set the st_ino field on files
2798 2004-11-01 Miklos Szeredi <miklos@szeredi.hu>
2800 * Fix compile problems with ancient (<=2.4.18) kernels (reported
2803 * Add "allow_root" mount option. Patch by Yaroslav Rastrigin
2805 * Clear the 'exited' flag when mail loop is finished
2807 2004-10-28 Miklos Szeredi <miklos@szeredi.hu>
2809 * Make xattr functions work under 2.6 (bug found by Vincenzo
2812 2004-10-26 Miklos Szeredi <miklos@szeredi.hu>
2814 * Reset request in fuse_flush() (bugreport by David Shaw)
2816 2004-10-21 Miklos Szeredi <miklos@szeredi.hu>
2818 * fuse_main() now does not exit on error, rather it returns an
2821 * Exported __fuse_setup() and __fuse_teardown() functions, which
2822 make it easier to implement a custom event loop.
2824 * Use daemon() call to background the filesystem after mounting.
2825 This function closes the standard input, output and error and
2826 changes the current working directory to "/".
2828 2004-10-14 Miklos Szeredi <miklos@szeredi.hu>
2832 2004-10-09 Miklos Szeredi <miklos@szeredi.hu>
2834 * Don't allow fuse_flush() to be interrupted (bug found by David
2837 2004-09-27 Miklos Szeredi <miklos@szeredi.hu>
2839 * Add PID to fuse_context. Patch by Steven James
2841 * Change file handle type to 'unsigned long' in kernel interface
2843 2004-09-22 Miklos Szeredi <miklos@szeredi.hu>
2845 * A slight API change: fuse_get_context() doesn't need the "fuse"
2846 pointer, but the returned context contains it instead. The
2847 fuse_get() function is not needed anymore, so it's removed.
2849 * Fix mounting and umounting FUSE filesystem under another FUSE
2850 filesystem by non-root (bug spotted by Valient Gough)
2852 2004-09-21 Miklos Szeredi <miklos@szeredi.hu>
2854 * Fix deadlock in case of memory allocation failure. Patch by
2857 2004-09-16 Miklos Szeredi <miklos@szeredi.hu>
2859 * Check memory allocation failures in libfuse
2861 2004-09-14 Miklos Szeredi <miklos@szeredi.hu>
2863 * Check temporary file creation failure in do_getdir(). Bug
2864 spotted by Terje Oseberg
2866 2004-09-13 Miklos Szeredi <miklos@szeredi.hu>
2868 * Allow "large_read" option for 2.6 kernels but warn of deprecation
2870 * Make requests non-interruptible so race with FORGET is avoided.
2871 This is only a temporary solution
2873 * Support compiling FUSE kernel module on 2.4.x UML kernels
2875 2004-09-09 Miklos Szeredi <miklos@szeredi.hu>
2877 * Fix bug in case two FORGETs for the same node are executed in
2878 the wrong order. Bug spotted and endured for months by Franco
2879 Broi, and logfile for solution provided by Terje Oseberg
2881 2004-09-01 Miklos Szeredi <miklos@szeredi.hu>
2883 * Add -D_REENTRANT to the compile flags
2885 * Add documentation of fuse internals by Terje Oseberg
2887 2004-08-16 Miklos Szeredi <miklos@szeredi.hu>
2889 * Change release method to be non-interruptible. Fixes bug
2890 causing missing release() call when program which has opened files
2891 is killed (reported by Franco Broi and David Shaw)
2893 2004-07-29 Miklos Szeredi <miklos@szeredi.hu>
2895 * Add fuse_invalidate() to library API
2897 2004-07-26 Miklos Szeredi <miklos@szeredi.hu>
2899 * Check permissions in setattr if 'default_permissions' flag is
2900 set. Bug spotted by Damjan Lango
2902 2004-07-24 Miklos Szeredi <miklos@szeredi.hu>
2904 * 'large_read' mount option removed for 2.6 kernels, since the
2905 default (dynamic read size) is better
2907 * Extend kernel API with file handles. A file handle is returned
2908 by open, and passed to read, write, flush, fsync and release.
2909 This is currently only used for debug output in the library.
2913 * Change the current directory to the mountpoint before checking
2914 the permissions and mount filesystem on "."
2916 * By default don't modprobe the fuse module for non-root. The old
2917 behavior can be restored with the '--enable-auto-modprobe' flag of
2920 * By default don't allow shared writable mappings for non-root.
2921 The old behavior can be restored with the 'user_mmap=1' module
2924 2004-07-23 Miklos Szeredi <miklos@szeredi.hu>
2926 * Clean up mount option passing to fusermount and to fuse_new()
2927 BEWARE: this changes the userspace API slightly, and the command
2928 line usage of programs using fuse_main()
2930 2004-07-20 Miklos Szeredi <miklos@szeredi.hu>
2932 * Optimize reading under 2.6 kernels by issuing multiple page
2933 asynchronous read requests
2935 2004-07-18 Miklos Szeredi <miklos@szeredi.hu>
2937 * Only use redirty_page_for_writepage() for kernels >= 2.6.6
2939 2004-07-16 Miklos Szeredi <miklos@szeredi.hu>
2941 * Separate directory entry and inode attribute validity timer
2943 * New write semaphore to stop page writeback during truncate
2945 * Fsync now waits for all writes to complete before sending the
2948 * Optimization: if a page is completely written by
2949 fuse_commit_write(), clear the dirty flag and set the uptodate
2952 * Some memory cleanup at exit
2954 2004-07-13 Miklos Szeredi <miklos@szeredi.hu>
2956 * Add FUSE_HARD_REMOVE flag, and '-i' option to fuse main, which
2957 disable the "hide if open" behavior of unlink/rename.
2959 * If temporary buffer allocation fails in raw read, fall back to a
2962 2004-07-12 Miklos Szeredi <miklos@szeredi.hu>
2964 * Fix bug in do_open() in libfuse: open count was incremented
2965 after the reply is sent so it could race with unlink/forget and
2968 2004-07-08 Miklos Szeredi <miklos@szeredi.hu>
2970 * When performing create or remove operation, refresh the parent's
2971 attributes on next revalidate, as i_nlink (and maybe size/time)
2974 * Use redirty_page_for_writepage() in fuse_writepage() for skipped
2977 * Set set_page_dirty address space operation (2.6 only)
2979 2004-07-06 Miklos Szeredi <miklos@szeredi.hu>
2981 * Minor fix in read: print debug info even if read size is zero
2983 2004-07-04 Miklos Szeredi <miklos@szeredi.hu>
2985 * Fix race between truncate and writepage (fsx-linux now runs
2988 2004-07-02 Miklos Szeredi <miklos@szeredi.hu>
2990 * Fix kernel hang on mkfifo under 2.4 kernels (spotted and patch
2993 * Added option for direct read/write (-r)
2995 * Fix revalidate time setting for newly created inodes
2997 * Remove uid==0 check for '-x' option in fusermount (kernel checks
3000 * fuse_main() only installs handlers for signals (out of INT, HUP,
3001 TERM, PIPE), for which no handler has yet been installed
3003 * Add module option 'user_allow_other' which if set to non-zero
3004 will allow non root user to specify the 'allow_other' mount option
3005 ('-x' option of fusermount)
3007 * Fix deadlock between page writeback completion and truncate
3008 (bug found by Valient Gough with the fsx-linux utility)
3010 2004-07-01 Miklos Szeredi <miklos@szeredi.hu>
3012 * Change passing fuse include dir to 2.6 kernel make system more
3013 robust (fixes compile problems seen on SuSE 9.1 with updated 2.6
3016 2004-06-30 Miklos Szeredi <miklos@szeredi.hu>
3018 * Acquire inode->i_sem before open and release methods to prevent
3019 concurrent rename or unlink operations.
3021 * Make __fuse_read_cmd() read only one command. This allows
3022 multiplexing the fuse file descriptor with other event sources
3023 using select() or poll() (patch by Jeff Harris)
3025 * Export 'exited' flag with __fuse_exited() (patch by Jeff Harris)
3027 2004-06-27 Miklos Szeredi <miklos@szeredi.hu>
3029 * Fix file offset wrap around at 4G when doing large reads
3031 2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
3033 * Fix memory leak in open (Valient Gough)
3035 2004-06-24 Miklos Szeredi <miklos@szeredi.hu>
3037 * Add "close after delete" support to libfuse (patch by Valient
3040 * Cancel all worker threads before exit in multithreaded mode
3042 2004-06-23 Miklos Szeredi <miklos@szeredi.hu>
3046 * Don't send reply to RELEASE
3048 * Work with newer libtool (1.5a)
3050 * Check for st_atim member of struct stat
3052 2004-06-22 Miklos Szeredi <miklos@szeredi.hu>
3054 * No request allocation needed on inode and file release
3056 2004-06-21 Miklos Szeredi <miklos@szeredi.hu>
3058 * Fix possible inode leak in userspace in case of unfinished
3059 lookup/mknod/mkdir/symlink/link operation.
3061 2004-06-20 Miklos Szeredi <miklos@szeredi.hu>
3063 * Fix some races and cleanups in fuse_read_super()
3065 2004-06-19 Miklos Szeredi <miklos@szeredi.hu>
3067 * Requests are allocated at open time
3069 2004-06-03 Miklos Szeredi <miklos@szeredi.hu>
3071 * Build shared library as well as static (using libtool)
3073 * Change FUSE_MINOR_VERSION from 1 to 0. I know it's illegal but
3074 there has not been a release with the previous minor number, and I
3075 hope nobody is using it for anything.
3077 * Change fuse_main(), so that default behavior is to go into
3078 background if mount is successful. '-f' and '-d' options disable
3079 backgrounding. This fixes the "Why does my FUSE daemon hang?"
3082 * Cache ENOSYS (function not implemented) errors on *xattr, flush
3085 * Don't call getdir method from open() only from first readdir().
3086 Open is sometimes just used to store the current directory
3089 2004-05-18 Miklos Szeredi <miklos@szeredi.hu>
3091 * Added flush() call
3093 2004-05-04 Miklos Szeredi <miklos@szeredi.hu>
3095 * Extended attributes support for 2.4 (patch by Cody Pisto)
3097 2004-04-20 Miklos Szeredi <miklos@szeredi.hu>
3099 * Fixed parser with modversions (Mattias Wadman)
3101 2004-04-19 Miklos Szeredi <miklos@szeredi.hu>

3105 2004-04-13 Miklos Szeredi <miklos@szeredi.hu>
3107 * Replaced binary mount data with text options
3109 * Show FUSE specific mount options in /proc/mounts
3111 * Check in fuse.h whether _FILE_OFFSET_BITS is set to 64
3113 2004-04-09 Miklos Szeredi <miklos@szeredi.hu>
3115 * Check some limits so userspace won't get too big requests
3117 2004-04-05 Miklos Szeredi <miklos@szeredi.hu>
3119 * Kill compile warning
3121 * Upgraded user-mount patch for 2.6.5
3123 2004-04-02 Miklos Szeredi <miklos@szeredi.hu>
3125 * Add detection of user-mode-linux to configure
3127 2004-03-31 Miklos Szeredi <miklos@szeredi.hu>
3129 * fixed zero size case for getxattr and listxattr
3131 2004-03-30 Miklos Szeredi <miklos@szeredi.hu>
3133 * new fusermount flag '-z': lazy unmount, default is not lazy
3135 * Extended attributes operations added (getxattr, setxattr,
3136 listxattr, removexattr)
3138 2004-03-25 Miklos Szeredi <miklos@szeredi.hu>
3140 * If filesystem doesn't define a statfs operation, then an
3141 all-zero default statfs is returned instead of ENOSYS
3143 2004-03-24 Miklos Szeredi <miklos@szeredi.hu>
3145 * Add FS_BINARY_MOUNTDATA filesystem flag for kernels > 2.6.4
3147 2004-03-09 Miklos Szeredi <miklos@szeredi.hu>
3149 * Fix for uClinux (Christian Magnusson)
3151 2004-03-02 Miklos Szeredi <miklos@szeredi.hu>
3153 * fuse_main() adds "-n progname" to the fusermount command line
3155 * More kernel interface changes:
3157 * Lookup/getattr return cache timeout values
3159 2004-02-25 Miklos Szeredi <miklos@szeredi.hu>
3161 * Clean up option parsing in fuse_main()
3163 * Added fuse_get() function which returns the fuse object created
3166 2004-02-20 Miklos Szeredi <miklos@szeredi.hu>
3168 * removed old way of mounting (fusermount mountpoint program)
3170 * more kernel interface changes:
3172 * added nanosecond precision to file times
3174 * removed interface version from mount data
3176 * added /proc/fs/fuse/version which contains MAJOR.MINOR
3178 2004-02-19 Miklos Szeredi <miklos@szeredi.hu>
3180 * statfs library API changed to match other methods. Since this
3181 is not backward compatible FUSE_MAJOR_VERSION is changed to 2
3183 * kernel interface changes follow:
3185 * statfs changed to 64 bits, added 'bavail' field
3187 * add generation number to lookup result
3189 * optimized mknod/mkdir/symlink/link (no separate lookup is
3192 * rdev size increased to 32 bits for mknod
3194 * kernel interface version changed to 3.1
3196 2004-02-18 Miklos Szeredi <miklos@szeredi.hu>
3198 * user-mount upgraded for 2.6.3 kernel
3200 2004-02-17 Miklos Szeredi <miklos@szeredi.hu>
3202 * Added user-mount.2.6.2-rc3.patch
3204 * Add FS_SAFE flag to fuse filesystem
3206 * fusermount should allow (un)mounting for non-root even if not
3209 2004-02-12 Miklos Szeredi <miklos@szeredi.hu>
3211 * Remove MS_PERMISSION mount flag (that means something else now)
3213 2004-02-10 Miklos Szeredi <miklos@szeredi.hu>
3215 * Added check for i_size_read/write functions to configure.in
3216 (patch by Valient Gough)
3218 2004-02-06 Miklos Szeredi <miklos@szeredi.hu>

3224 * Readpage calls flush_dcache_page() after storing data
3226 * Use i_size_read/write for accessing inode->i_size
3228 * Make loopback mount of a fuse file work
3230 2004-02-04 Miklos Szeredi <miklos@szeredi.hu>
3234 2004-01-29 Miklos Szeredi <miklos@szeredi.hu>
3236 * Properly check if the inode exists in fuse_invalidate
3238 2004-01-27 Miklos Szeredi <miklos@szeredi.hu>
3240 * Added -q option for fusermount
3242 * fuse_unmount() now uses -q option of fusermount, so no error is
3243 printed if the cause of the program exit is that the filesystem
3244 has already been unmounted
3246 * Fix i_nlink correctness after rmdir/unlink
3248 2004-01-26 Miklos Szeredi <miklos@szeredi.hu>
3252 2004-01-26 Miklos Szeredi <miklos@szeredi.hu>
3254 * Fix typo (thanks Marcos Dione)
3256 * Compile fixes for 2.4 kernels
3258 2004-01-23 Miklos Szeredi <miklos@szeredi.hu>
3260 * Fix CONFIG_MODVERSIONS compile on 2.6
3262 2004-01-22 Miklos Szeredi <miklos@szeredi.hu>
3264 * Write all pending data before a RELEASE operation
3266 * Suppress 'Bad file descriptor' warning on exit
3268 * Replaced fusermount option '-d xxx' with '-n xxx' so it doesn't
3269 get confused with '-d' of fuse_main() (sorry about this change)
3271 * New fusermount option '-l' which enables big reads. Big reads
3272 are now disabled by default.
3274 * fuse_main() can accept fusermount arguments after a '--'
3276 2004-01-19 Miklos Szeredi <miklos@szeredi.hu>

3334 2003-12-11 David McNab <david@rebirthing.co.nz>
3336 * Python filesystem - was broken with python2.3, now fixed:
3337 - changed PyTuple_* calls to PySequence_*, because os.lstat
3338 is no longer returning a pure tuple
3339 - changed PyInt_Check() calls to also call PyLong_Check,
3340 to cover for cases (eg os.lstat) where longs are returned
3341 - Added support for file 'release' handling, which IMO is
3342 essential since this signals to a FS that writes to a file
3343 are complete (and therefore the file can now be disposed of
3344 meaningfully at the python filesystem's discretion)
3345 - Added '__init__' handler to base Fuse class, which allows
3346 your Python class to know the mountpoint and mount args,
3347 as attributes myfs.mountpoint, myfs.optlist, myfs.optdict
3350 - added 'mount.fuse' script (in util/ dir), which is meant to be
3351 symlinked from /sbin, and which allows FUSE filesystems to
3352 be mounted with the 'mount' command, and listed in fstab;
3353 also, mount arguments get passed to your filesystem
3356 2003-11-04 Miklos Szeredi <miklos@szeredi.hu>
