* fusermount, libfuse: send value as unsigned in "user_id=" and
"group_id=" options. Uids/gids larger than 2147483647 would
result in EINVAL when mounting the filesystem. This also needs a
fix in the kernel.
2014-03-26 Miklos Szeredi <>

filesystem could deadlock because of a bug in the way the paths
are locked. Reported by Kazuaki Anami
2012-08-23 Miklos Szeredi <>
* Fix missing config.h in buffer.c. Reported by Matthew Gabeler-Lee
2012-08-14 Miklos Szeredi <>
* Not unhashing the name in forget (commit on 2011-12-09) broke
the forget logic in a subtle way, resulting in "fuse internal
error: node NNN not found" and causing the filesystem daemon to
abort. Fix by incrementing the node refcount if nlookup goes from
zero to one. Reported by Kyle Lippincott

later. Patch by Anatol Pomozov
2012-05-16 Miklos Szeredi <>
* Linking to a library that uses threads requires the application
to be linked with -pthreads otherwise some pthread functions will
be linked to stubs in glibc. So move -pthread from Libs.private
to Libs in fuse.pc. Reported by Werner Fink
* Fix the compile command in the examples. Reported by Luciano
Dalle Ore
2012-04-20 Miklos Szeredi <>
* Released 2.9.0
2012-04-20 Miklos Szeredi <>

2012-04-10 Miklos Szeredi <>
* Check protocol version before sending notifications and return
-ENOSYS if a particular notification is not supported.
* Add 'flag_utime_omit_ok' flag to fuse_operations. If the
filesystem sets this flag then ->utimens() will receive UTIME_OMIT
and UTIME_NOW values as specified in utimensat(2).
2012-01-27 Miklos Szeredi <>

returned for unlinked but still open files if the kernel sent a
FORGET request for the parent directory.
* Free request in fuse_reply_data().
2011-12-08 Miklos Szeredi <>
* Fix build if FUSE_NODE_SLAB is not defined. Patch by Emmanuel
* Check for availability of utimensat() function. Patch by
Emmanuel Dreyfus
2011-12-07 Miklos Szeredi <>

file or directory is deleted. Patch by John Muir
2011-12-06 Miklos Szeredi <>
* Update retrieve_reply() method
2011-12-05 Miklos Szeredi <>
* Low level API: lock argument of fuse_reply_lock should have a
'const' qualifier. Reported by Shachar Sharon
* Add support for ioctl on directories. Reported by Antonio SJ
2011-10-13 Miklos Szeredi <>
* Reply to request with ENOMEM in case of failure to allocate

* Replace daemon() function with fork(). Patch by Anatol Pomozov
2011-08-26 Miklos Szeredi <>
* If configured with --disable-mtab then don't call mount(8) from
libfuse to update the mtab. Reported by: James Sierp
2011-08-24 Miklos Szeredi <>
* Use LRU list for cleaning up the cache if the "remember=T"
option was given. Patch by
2011-07-06 Miklos Szeredi <>
* Add ->flock() operation to low and high level interfaces. This
fixes problems with emulating flock() with POSIX locking.
Reported by Sebastian Pipping. As with lock/setlk/getlk most
filesystems don't need to implement this, as the kernel takes care
of file locking. The only reason to implement locking operations
is for network filesystems which want file locking to work between
2011-07-02 Sebastian Pipping <>
* Make xmp_utimens of examples "fusexmp" and "fusexmp_fh"
not follow symlinks as other layers do that already.
2011-06-02 Miklos Szeredi <>
* Add "remember" option. This works similar to "noforget" except
that eventually the node will be allowed to expire from the cache.
Patch by
2011-05-27 Miklos Szeredi <>
* Check if splice/vmsplice are supported
2011-05-26 Miklos Szeredi <>
* Remove -lrt -ldl from fuse.pc for dynamic linking since is already linked with these libraries. Reported by:
Nikolaus Rath
2011-05-20 Miklos Szeredi <>
* Cleaner build output. Patch by Reuben Hawkins
2011-05-19 Miklos Szeredi <>
* Disable splice by default, add "splice_read", "splice_write" and
"splice_move" options. Keep the "no_splice_*" variants, which can
disable splice even if the filesystem explicitly enables it.
2011-04-15 Max Krasnyansky <>
* Added support for "auto_unmount" option which unmounts the
filesystem automatically on process exit (or crash).
2011-03-30 Miklos Szeredi <>
* Patches by Laszlo Papp fixing various issues found by the
Coverity checker
2011-03-11 Miklos Szeredi <>
* In case of failure to add to /etc/mtab don't umount. Reported
by Marc Deslauriers
2011-02-02 Miklos Szeredi <>
* libfuse: In fuse_session_loop_mt() don't pause when exiting the
worker threads. The pause() was added in 2.2.1 to prevent
segfault on pthread_cancel() on an exited, detached thread. Now
worker threads are not detached and pthread_cancel() should work
fine even after the thread exited. Reported by Boris Protopopov
2011-01-31 Miklos Szeredi <>
* fusermount: chdir to / before performing mount/umount
* fusermount: only allow mount and umount if util-linux supports
2010-12-16 Miklos Szeredi <>
* Highlevel lib: allow hash tables to shrink
* Highlevel lib: add slab allocation for node cache. This will
allow the memory used by the filesystem to grow and shrink
depending on how many inodes are currently cached.
2010-12-13 Miklos Szeredi <>
* Highlevel lib: use dynamically resized hash table for looking up
by name and node ID.
2010-12-07 Miklos Szeredi <>
* Allow batching of forget requests. This allows forget requests
to be processed faster and doesn't require a modification to fuse
filesystems. Reported by Terje Malmedal
* Add ->forget_multi() operation to the lowlevel API. The
filesystem may implement this to process multiple forget requests
in one call
* Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
for 32bit vs. 64bit userspace
2010-11-10 Miklos Szeredi <>
* Add new write_buf() method to the highlevel API. Similarly to
the lowlevel write_buf() method, this allows implementing zero
copy writes.
* Add a new read_buf() method to the highlevel API. This allows
returning a generic buffer from the read method, which in turn
allows zero copy reads.
* In fusexmp_fh implement the ->read_buf() and ->write_buf()
methods. Leave the ->read() and ->write() implementations for
reference, even though they are not necessary.
2010-11-08 Miklos Szeredi <>
* Fix check for read-only fs in mtab update
* Open /dev/null for write instead of read for redirecting stdout
and stderr
* If umount(8) supports --fake and --no-canonicalize (util-linux-ng
version 2.18 or later), and umount(2) supports the
UMOUNT_NOFOLLOW flag (linux kernel version 2.6.35 or later) then,
"fusermount -u" will call the umount(2) system call and use
"umount --fake ..." to update /etc/mtab
* Added --disable-legacy-umount option to configure. This
disables the runtime checking of umount(8) version. When built
with this option then "fusermount -u" will fail if umount(8)
doesn't support the --fake and --no-canonicalize options.
* Fix fuse_buf_copy() if already at the end of the buffers
* Add new ->write_buf() method to low level interface. This
allows passig a generic buffer, either containing a memory buffer
or a file descriptor. This allows implementing zero copy writes.
* Add fuse_session_receive_buf() and fuse_session_process_buf()
which may be used in event loop implementations to replace
fuse_chan_recv() and fuse_session_process() respectively.
* Remove unnecessary restoring of current working directory in
"fusermount -u"
* Add ctx->pid to debug output
* Fix st_nlink value in high level lib if file is unlinked but
still open
* libfuse: add store request. Request data to be stored in the
kernel buffers for a given inode.
* libfuse: add retrieve request. Retrieve data stored in the
kernel buffers for a given inode.
2010-10-14 Miklos Szeredi <>
* Use LTLIBICONV when linking libfuse. This fixes building against
uclibc + libiconv. Patch by Natanael Copa
2010-10-05 Miklos Szeredi <>
* Add missing argument check in ulockmgr.c to prevent calling
ulockmgr_server with illegal arguments. This would cause an ever
growing list of ulockmgr_server processes with an endless list of
open files which finally exceeds the open file handle limit.
Patch by Markus Ammer
2010-09-28 Miklos Szeredi <>
* Fix ambiguous symbol version for fuse_chan_new.
fuse_versionscript included fuse_chan_new in both FUSE_2.4 and
FUSE_2.6. Remove the FUSE_2.4, which is invalid.
2010-09-28 Miklos Szeredi <>
* Fix option escaping for fusermount. If the "fsname=" option
contained a comma then the option parser in fusermount was
confused (Novell bugzilla #641480). Fix by escaping commas when
passing them over to fusermount. Reported by Jan Engelhardt
2010-08-27 Miklos Szeredi <>
* Add NetBSD support. Patch from Emmanuel Dreyfus
2010-07-12 Miklos Szeredi <>
* libfuse: add buffer interface. Add a generic buffer interface
for use with I/O. Buffer vectors are supplied and each buffer in
the vector may be a memory pointer or a file descriptor.
* The fuse_reply_fd() interface is converted to using buffers.
2010-06-23 Miklos Szeredi <>
* Make the number of max background requests and congestion
threshold tunable. New options are "max_background" and
"congestion_threshold". Only effective on linux kernel versions
2.6.32 or greater. Patch by Csaba Henk
2010-06-17 Miklos Szeredi <>
* Add fuse_reply_fd() reply function to the low level interface.
On linux version 2.6.35 or greater this will use splice() to move
data directly from a file descriptor to the fuse device without
needing to go though a userspace buffer. With the
FUSE_REPLY_FD_MOVE flag the kernel will attempt to move the data
directly into the filesystem's cache. On earlier kernels it will
fall back to an intermediate buffer. The options
"no_splice_write" and "no_splice_move" can be used to disable
splicing and moving respectively.
2010-06-15 Miklos Szeredi <>
* Fix out-of-source build. Patch by Jörg Faschingbauer
* Add a "nopath" option and flag, indicating that path argument
need not be calculated for the following operations: read, write,
flush, release, fsync, readdir, releasedir, fsyncdir, ftruncate,
fgetattr, lock, ioctl and poll.
2010-05-10 Miklos Szeredi <>

* Released 2.8.3
2010-02-01 Miklos Szeredi <>
* Using "--no-canonicalize" with umount(8) conflicts with the race
fix, sinceit assumes the supplied path is absolute, while the race
fix relies on the path being relative to the current directory.
Reported by Tom Rindborg
2010-01-26 Miklos Szeredi <>
* Released 2.8.2
2010-01-21 Miklos Szeredi <>
* Fix race if two "fusermount -u" instances are run in parallel.
Reported by Dan Rosenberg
* Make sure that the path to be unmounted doesn't refer to a
2010-01-14 Miklos Szeredi <>
* Fix compile error on FreeBSD. Patch by Jay Sullivan
2009-12-17 Miklos Szeredi <>
* Use '--no-canonicalize' option of mount(8) (available in
util-linux-ng version 2.17 or greater) to avoid calling
readling(2) on the newly mounted filesystem before the mount
procedure is finished. This has caused a deadlock if "audit" was
enabled in the kernel. Also use '--no-canonicalize' for umount to
avoid touching the mounted filesystem.
2009-09-11 Miklos Szeredi <>
* Released 2.8.1
2009-08-25 Miklos Szeredi <>
* Fix missing versioned symbol fuse_get_context@FUSE_2.2
2009-08-18 Miklos Szeredi <>
* Released 2.8.0
2009-08-18 Miklos Szeredi <>
* Add missing fuse_session_data to versionscript
* Make sure all global symbols are prefixed with "fuse_" or "cuse_"
2009-07-16 Miklos Szeredi <>
* Clarify how the protocol version should be negotiated between
kernel and userspace. Notably libfuse didn't correctly handle the
case when the supported major versions didn't match
* Add missing pthread link for libulockmgr. Patch by Petr Salinger
2009-07-02 Miklos Szeredi <>
* The context is extended with a 'umask' field. The umask is sent
for mknod, mkdir and create requests by linux kernel version
2.6.31 or later, otherwise the umask is set to zero. Also
introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel
supports this feature, then this flag will be set in conn->capable
in the ->init() method. If the filesystem sets this flag in in
conn->want, then the create modes will not be masked.
* Add low level interfaces for lookup cache and attribute
invalidation. This feature is available in linux kernels 2.6.31
or later. Patch by John Muir
* Kernel interface version is now 7.12
* fusermount: Do not silently ignore command line arguments.
Patch by Sebastian Harl
2009-06-19 Miklos Szeredi <>
* Released 2.8.0-pre3
2009-06-19 Miklos Szeredi <>
* Add fuse_getgroups (high level lib) and fuse_req_getgroups (low
level lib) functions to query the supplementary group IDs for the
current request. Currently this is implemented on Linux by
reading from the /proc filesystem.
2009-06-18 Miklos Szeredi <>
* Add "noforget" option to high level lib to prevent ESTALE errors
on NFS exported filesystems. This result in paths being cached
forever, resulting in ever growing memory usage. Use with care.
* Add "no_remote_lock" option to disable remote file locking even
if the filesystem implements it. With this option locking
primitives (flock, lockf, fcntl(F_SETLK)) will still work, but
will ignore remotely locked files.
* CUSE patches from Tejun Heo:
* Unrestricted ioctl support left some debris. Clean them up:
o No reason to pass around pointer to flags. Pass flags directly.
o Clean up comment and prototype parameter names.
o fuse_lib_ioctl() didn't reply when get_path() failed. Fix it.
o Remove unused variables {in|out}_iov from fuse_lib_ioctl().
* Add fuse_reply_ioctl_iov()
* Move fuse_session, fuse_req and fuse_ll definitions to fuse_i.h
and make send_reply_iov() and fuse_setup_common() global (also in
fuse_i.h). These will be used by CUSE support.
* Restructure fuse_ll_process()
* Implement libfuse side of CUSE support. CUSE uses subset of FUSE
operations as dir operations don't make sense for CUSE where one
instance implements single character device.
CUSE support comes with its own cuse_lowevel_ops and related
initialization and helper functions. Except for initialization, it
usage is basically identical to FUSE.
This patch also adds example/cusexmp.c which can create a character
device with name and device number specified on command line. The
created device itself is pretty boring. It's a bit bucket supporting
read, write and access via ioctl.
2009-06-16 Miklos Szeredi <>
* Add missing fuse_reply_bmap to versionscript. Debian
Bug#531329. Reported by Goswin Brederlow
2009-05-27 Miklos Szeredi <>

* Implement poll support. Patch by Tejun Heo
* Add missing setattr flags to <fuse_lowlevel.h>.
* Only pass valid flags to ->setattr().
2008-12-05 Miklos Szeredi <>
* Implement ioctl support. On high level interface only
"restricted" ioctls are supported (which are defined with the
_IO(), _IOR(), _IOW() or _IOWR() macros). Unrestricted ioctls
will only be allwed to CUSE (Character Device in Userspace)
servers. Patch by Tejun Heo
2008-11-28 Miklos Szeredi <>

* Don't allow bigger than 4kB writes by default on 2.6.26 and
later kernels, so that filesystems not expecting this are not

* lib/mount_bsd.c:
- string formatting fixes
- exit if mounting has failed
(in FreeBSD a mount failure is not critical per se, as the daemon
still could be mounted externally, but waiting for such an event
is more confusing than fruitful)
- ditch the kvm(8) stuff and simply use forced unmount which just
won't block
- prettify option specifications
- add "-onosync_unmount" kernel option

calls to i_size_read() to spin forever. This is a long standing
bug was probably introduced in version 2.2, and thought to be

* Make sure inode numers wrap around at 2^32. This is needed on
dual 64bit/32bit architectures, because 32bit applications using
the non-largefile interface would otherwise break (EOVERFLOW error
would be returned by the stat() system call family)
* ulockmgr: handle the case, when a locking operation fails
because no more file desctriptors are available in
ulockmgr_server. Also work around a Linux kernel bug (known to
exist for all Linux kernel versions <= 2.6.18) which may cause
sent file descriptors to be lost in the above case
* ulockmgr: optimize file descriptor use
* restore needed cpp flags to util/
* Install udev rules as 99-fuse.rules instead of 60-fuse.rules
* Minor clean up of udev rules
* Add a synchronous DESTROY message to kernel interface. This is
invoked from umount, when the final instance of the filesystem is
released. It is only sent for filesystems mounted with the
'blkdev' option for security reasons.
* If the DESTROY message is received, call the filesystem's
->destroy() method. In this case it's not called from session
destruction as it would be otherwise.
2006-10-01 Miklos Szeredi <>
* Released 2.6.0-rc2
2006-10-01 Miklos Szeredi <>
* Add support for FLUSH+RELEASE operation for FreeBSD. Original
patch by Csaba Henk
* Add init script to insert fuse module and mount the control
filesystem. The script is installed as /etc/init.d/fuse and on
debian based systems (where update-rc.d is available) symlinks
from /etc/rc*.d/ are also installed.
* Include '#define FUSE_USE_VERSION=XX' into examples so they
become more self contained.
2006-09-30 Miklos Szeredi <>
* API changes:
* Move lock_owner from a separate argument into fuse_file_info
* Add a flag to fuse_file_info indicating (1) a highlevel lock
operation (unlock all) was initiated by a flush, (2) a lowlevel
release operation should perform a flush as well.
* fusermount: revert modprobe change (2006-08-18) since it
doesn't work reliably with udev
* Add support for block device backed filesystems. This mode is
selected with the 'blkdev' option, which is privileged.
* Add support for the bmap (FIBMAP ioctl) operation on block
device backed filesystems. This allows swapon and lilo to work on
such filesystems.
* kernel changes:
* Drop support for kernels earlier than 2.6.9. Kernel module from
previous (2.5.x) release can be used with library from this
* In fuse_dentry_revalidate() use dget_parent() instead of
dereferencing d_parent, since there's no protection against parent
changing and going away
* Protect nlookup from concurrent updates
* In lookup if a directory alias exists but is unused,
then get rid of it, otherwise return -EBUSY.
* In mkdir if a directory alias exists, return success, but leave
dentry negative. In reality this could happen if a remote rename
immediately followed the mkdir.
* Don't BUG in fuse_iget() if multiple retries are needed to get a
good inode. This could happen if several lookups are racing for
the same inode.

2006-09-07 Miklos Szeredi <>
* lib: Add interrupt support to high level library, which may be
enabled with the 'intr' mount option.
* When an operation is interrupted the thread handling that
operation will receive SIGUSR1 (or other signal specified with the
'intr_signal=N' option). The library installs a no-op signal
handler for this signal, unless there's already a handler
* The filesystem may query interrupt status (regardless of 'intr')
with the fuse_interrupted() function.
* mount.fuse: initialize $HOME if not set. Report from Sven Goldt
2006-09-03 Miklos Szeredi <>
* lib: Multithreaded loop now allows unlimited number of threads.
This is needed for locking operations which may block
indefinitely. Also the kernel now doesn't limit the number of
outstanding requests so the library shouldn't do so either.

the filesystem on which the stat(v)fs syscall was called
* fusermount: try to modprobe fuse module if invoked by root and
unable to open device. This is needed with udev, since the device

hello_ll so that device doesn't get closed before unmount attempt.
2006-02-25 Miklos Szeredi <>
* Lowlevel lib: return all-zero statvfs data if filesystem doesn't

2006-01-07 Miklos Szeredi <>
* Improved help reporting and added version reporting to library
2006-01-06 Miklos Szeredi <>
* Change working directory to "/" even if running in the
foreground. Patch from Jonathan Brandmeyer
* Changed lots of functions to use 'struct fuse_args' instead of
separate argc and argv
* Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
fuse_remove_signal_handlers() functions, so that it's now pretty
easy to get all the functionality of fuse_main() with a filesystem
using the lowlevel API.
2006-01-02 Miklos Szeredi <>
* mount.fuse: the 'user' option should be ignored. Report and
solution from Mattd.
* mount.fuse: export PATH in the right place. Report and patch
from Hannes Schweizer

* fusermount: check if /mnt/mtab is a symlink and don't modify it
in that case
* kernel: simplify request size limiting. INIT only contains
maximum write size, maximum path component size remains fixed at
1024 bytes, and maximum xattr size depends on read buffer.
2005-12-14 Miklos Szeredi <>

configuring for a 2.4.x kernel. Bug report by Mark Haney
* In multithreaded loop send a TERM signal to the main thread if
one of the other threads exit. Needed on FreeBSD for a clean exit
on umount. Should not cause any harm on Linux either
2005-11-28 Miklos Szeredi <>
* Fix bug in 32-bit file handle compatibility
2005-11-27 Miklos Szeredi <>
* Block TERM, INT, HUP and QUIT signals in all but the main
thread. According to POSIX it's not specified which thread will
receive these signals.
* Kernel changes:
* Check for directory aliasing on mkdir, not just on lookup
* Check for special node ID values in create+open operation
* Sync with -mm: readv, writev, aio_read and aio_write methods
added to file operations
* Cleanups: lookup code, page offset calculation
* ABI stepped to 7.4, changes:
* frsize member added to fuse_kstatfs structure
* added support for negative entry caching: on lowlevel API if
fuse_entry_param::ino is set to zero in reply to a lookup request,
the kernel will cache the dentry for the specified amount of time.
* libfuse: added 'negative_timeout' option: specifies how much
negative entries should be cached. Default is zero, to be
compatible with prior versions
2005-11-22 Miklos Szeredi <>
* Add detection of mainline FUSE code in running kernel
2005-11-21 Miklos Szeredi <>

2005-11-11 Miklos Szeredi <>
* Use 64bit type for file handle, so the full range supported by
the kernel interface is available to applications
2005-11-10 Miklos Szeredi <>
* Moved mountpoint argument checking from fuse_parse_cmdline() to
fuse_mount() in preparation to FreeBSD merge.
2005-11-08 Miklos Szeredi <>

2005-11-07 Miklos Szeredi <>
* Make the statfs change backwards compatible.
2005-11-06 Miklos Szeredi <>
* Change ->statfs() method to use 'struct statvfs' instead of
'struct statfs'. This makes the API more portable since statvfs()
is defined by POSIX.
2005-10-28 Miklos Szeredi <>
* Add fgetattr() method, which currently will only be called after
a successful call to a create() method.
2005-10-26 Miklos Szeredi <>
* Change kernel ABI version to 7.3
* Add ACCESS operation. This is called from the access() system
call if 'default_permissions' mount option is not given, and is
not called on kernels 2.4.*

automatic umounting in fuse_main(). Bugreport by Václav Jůza
2005-08-03 Miklos Szeredi <>
* fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
option is used (Paul Alfille).
2005-08-02 Miklos Szeredi <>
* highlevel-lib: added mount options "attr_timeout" and
"entry_timeout". These options control the length of time file
attributes and entries (names) are cached. Both default to 1.0
* kernel: correctly handle zero timeout for attributes and entries
2005-08-01 Miklos Szeredi <>
* Added missing symbols to versionscript (Joshua J. Berry)
* kernel: implement two flags, open can set: 'direct_io' and
'keep_cache'. These correspond exactly to mount options
'direct_io' and 'kernel_cache', but allow a per-open setting.
* Move 'direct_io' and 'kernel_cache' mount option handling to
userspace. For both mount options, if the option is given, then
the respective open flag is set, otherwise the open flag is left
unmodified (so the filesystem can set it).
* lib (highlevel): make open method optional
2005-07-28 Miklos Szeredi <>

2005-07-22 Miklos Szeredi <>
* Fix bug, that causes filesystem requests to hang when unique
request counter becomes negative. This happens after
2,147,483,648 operations, so most people won't care. Thanks to
Franco Broi for the report and testing.
2005-07-21 Miklos Szeredi <>
* Don't change mtime/ctime/atime to local time on read/write.
Bug reported by Ben Grimm
* Install fuse_common.h and fuse_lowlevel.h. Report by Christian
* fusermount: use getopt_long() for option parsing. It allows the
use of '--' to stop argument scanning, so fusermount can now
operate on directories whose names begin with a '-'. Patch by
Adam Connell
2005-07-15 Miklos Szeredi <>
* fusermount: add '-v', '--version' and '--help' options

2005-07-07 Miklos Szeredi <>
* lib: don't allow both 'allow_other' and 'allow_root' options to
be given
2005-07-06 Miklos Szeredi <>
* fusermount: check if mountpoint is empty (only '.' and '..' for
directories, and size = 0 for regular files). If "nonempty"
option is given, omit this check. This is useful, so users don't
accidentally hide data (e.g. from backup programs). Thanks to
Frank van Maarseveen for pointing this out.
* kernel: check if mandatory mount options ('fd', 'rootmode',
'user_id', 'group_id') are all given
* lib: simplify 'readdir_ino' handling
* lib: add mount options 'umask=M', 'uid=N', 'gid=N'

2005-06-08 Miklos Szeredi <>
* Enable the auto-loading of the module via access to the
corresponding device file. Patch by Takashi Iwai.
* Allow mounting a regular file (over a regular file) for
unprivleged users.
* Do not create temporary device file. Require "/dev/fuse" to
exist, and be readable/writable by the mounting user.
2005-06-02 Miklos Szeredi <>
* Released 2.3.0
2005-06-02 Miklos Szeredi <>
* Fix serious information leak: if the filesystem returns a short
byte count to a read request, and there are non-zero number of
pages which are not filled at all, these pages will not be zeroed.
Hence the user can read out previous memory contents. Found by
Sven Tantau.
2005-05-27 Miklos Szeredi <>
* Add "readdir_ino" mount option, which tries to fill in the d_ino
field in struct dirent. This mount option is ignored if "use_ino"
is used. It helps some programs (e.g. 'pwd' used over NFS from a
non-Linux OS). Patch by David Shaw.
2005-05-12 Miklos Szeredi <>
* Released 2.3-rc1
2005-05-12 Miklos Szeredi <>
* File save in krusader and other editors doesn't work with sshfs,
because open() is interrupted by a periodic signal, and open()
restarts forever, without any progress. This could just be fixed
in open(), but the problem is more generic: if signals are
received more often than the filesystem can get the request to
userspace, it will never finish. This is probably only a
theoretical problem, nevertheless I'm removing the possibility to
interrupt requests with anything other than SIGKILL, even before
being sent to userspace. Bugreport by Eduard Czimbalmos.
2005-05-09 Miklos Szeredi <>
* libfuse: add "tree_lock" rwlock, that is locked for write in
rename, unlink and rmdir, and locked for read in all other
operations. This should fix the rename/release race reported by
Valient Gough and others. The solution is very coarse, a finer
grained locking scheme could be implemented, but it would be much
more complex. Let's see whether this is good enough.
2005-05-09 Miklos Szeredi <>
* Released 2.3-pre7
2005-05-08 Miklos Szeredi <>
* Better fix for out of order FORGET messages. Now the
LOOKUP/FORGET messages are balanced exactly (one FORGET can
balance many lookups), so the order no longer matters. This
changes the kernel ABI slightly, but the library remains backward
2005-05-06 Miklos Szeredi <>
* Fix abort for out of order FORGET messages. Again. Spotted by
Franco Broi again. Sorry :)
2005-04-29 Miklos Szeredi <>
* Released 2.3-pre6
2005-04-29 Miklos Szeredi <>
* Make fusermount work with fuse kernel modules not yet supporting
the "group_id" option (added for the purpose of stricter
permission checking).
2005-04-28 Miklos Szeredi <>
* Check for hard-linked directories in lookup. This could cause
problems in the VFS, which assumes that such objects never exist.
* Make checking of permission for other users more strict. Now
the same privilege is required for the mount owner as for ptrace
on the process performing the filesystem operation.

2005-01-04 Miklos Szeredi <>
* KERNEL: if request is interrupted, still keep reference to used
inode(s) and file, so that FORGET and RELEASE are not sent until
userspace finishes the request.
* remove /{sys,proc}/fs/fuse/version, and instead add an INIT
request with the same information, which is more flexible,
simpler, works on embedded systems.
2004-12-16 Miklos Szeredi <>
* KERNEL ABI: update interface to make it independent of type
sizes. This will help on 64 bit architectures which can run
legacy 32 bit applications.
* KERNEL ABI: add "len" field to request headers. This will allow
sending/receiving requests in multiple chunks.
* KERNEL: handle file type change more intelligently
* LIB: "-o debug" option should disable backgrounding (fix by
Fabien Reygrobellet)
2004-12-13 Miklos Szeredi <>
* KERNEL: invalidate dentry/attributes if interrupted request
could leave filesystem in an unknown state.
2004-12-12 Miklos Szeredi <>
* KERNEL: lots of cleanups related to avoiding possible deadlocks.
These will cause some regressions, but stability is considered
more important. If any of these features turns out to be
important, it can be readded with the deadlock problems addressed.
* Make all requests interruptible (only with SIGKILL currently).
This can be used to break any deadlock produced by the userspace
filesystem accessing it's own exported files. The RELEASE request
is special, because if it's interrupted before sending it to
userspace it is still sent, but the reply is not awaited.
* If request is interrupted before being sent to userspace, and if
it hasn't yet got any side effects, it is always restarted,
regardless of the SA_RESTART flag. This makes these interruptions
transparent to the process.
* Remove shared-writable mmap support, which was prone to an
out-of-memory deadlock situation
* Remove INVALIDATE userspace initiated request
* Make readpages() synchronous. Asynchronous requests are
deadlock prone, since they cannot be interrupted.
* Add readv/writev support to fuse device operations
* Remove some printks, which userspace FS can use for a DoS
against syslog
* Remove 'large_read' mount option from 2.6 in kernel, check it in
fusermount instead
* LIB: improve compatibility with a fuse.h header installed in
${prefix}/include which in turn includes the real header.
* LIB: improve compatibility by defining fuse_main() (which is now
not used), so old configure scripts find it.

* kernel: clean up reading functions
2004-11-29 Miklos Szeredi <>
* kernel: make readpage() uninterruptible
* kernel: check readonly filesystem flag in fuse_permission
* lib: don't die if version file not found and new style device
* lib: add '-r' option, which is short for '-o ro'
* fusermount: simplify device opening
* kernel: when direct_io is turend on, copy data directly to
destination without itermediate buffer. More efficient and safer,
since no allocation is done.
* fusermount: fix warning if fuse module is not loaded
* kernel: use /dev/fuse on 2.4 too
2004-11-26 Miklos Szeredi <>
* libfuse API change: open, read, write, flush, fsync and release
are passed a 'struct fuse_file_info' pointer containing the open
flags (open and release), and the file handle. Verion changed to

the 'max_read' mount option
* fixes for UCLIBC (Christian Magnusson)
2004-11-19 Miklos Szeredi <>
* Cleaned up kernel in preparation for merge into mainline:

* Make libfuse and fusermount compatible with future versions
* fusermount: properly add mount options to /etc/mtab
2004-11-15 Miklos Szeredi <>
* fusermount: do not resolve last component of mountpoint on if it
is '.' or '..'. This new path resolvation is now done on mount as
well as unmount. This enables relative paths to work on unmount.
* fusermount: parse common mount options like "ro", "rw", etc...

2004-11-08 Miklos Szeredi <>
* Add ino argument to 'fuse_dirfil_t'. NOTE: This breaks source
compatibility with earlier versions. To compile earier versions
just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
Do not use the "use_ino" mount flag with filesystems compiled with
* Add pkg-config support. To compile a FUSE based filesystem you
can do "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
or similar. Note, that the PKG_CONFIG_PATH environment variable
usually needs to be set to "/usr/local/lib/pkgconfig".
* fuse.h is now installed in ${prefix}/include/fuse/
2004-11-02 Miklos Szeredi <>

This function closes the standard input, output and error and
changes the current working directory to "/".

* Add PID to fuse_context. Patch by Steven James
* Change file handle type to 'unsigned long' in kernel interface
2004-09-22 Miklos Szeredi <>
* A slight API change: fuse_get_context() doesn't need the "fuse"
pointer, but the returned context contains it instead. The
fuse_get() function is not needed anymore, so it's removed.
* Fix mounting and umounting FUSE filesystem under another FUSE
filesystem by non-root (bug spotted by Valient Gough)

2004-07-24 Miklos Szeredi <>
* 'large_read' mount option removed for 2.6 kernels, since the
default (dynamic read size) is better
* Extend kernel API with file handles. A file handle is returned
by open, and passed to read, write, flush, fsync and release.
This is currently only used for debug output in the library.
* Security changes:
* Change the current directory to the mountpoint before checking
the permissions and mount filesystem on "."
* By default don't modprobe the fuse module for non-root. The old
behavior can be restored with the '--enable-auto-modprobe' flag of

flag for that page
* Some memory cleanup at exit
2004-07-13 Miklos Szeredi <>
* Add FUSE_HARD_REMOVE flag, and '-i' option to fuse main, which
disable the "hide if open" behavior of unlink/rename.
* If temporary buffer allocation fails in raw read, fall back to a
smaller buffer
2004-07-12 Miklos Szeredi <>
* Fix bug in do_open() in libfuse: open count was incremented
after the reply is sent so it could race with unlink/forget and
cause an abort.
2004-07-08 Miklos Szeredi <>
* When performing create or remove operation, refresh the parent's
attributes on next revalidate, as i_nlink (and maybe size/time)
could be inacurate.

will allow non root user to specify the 'allow_other' mount option
('-x' option of fusermount)

2004-06-03 Miklos Szeredi <>
* Build shared library as well as static (using libtool)
* Change FUSE_MINOR_VERSION from 1 to 0. I know it's illegal but
there has not been a release with the previous minor number, and I
hope nobody is using it for anything.
* Change fuse_main(), so that default behavior is to go into
background if mount is successful. '-f' and '-d' options disable
backgrounding. This fixes the "Why does my FUSE daemon hang?"
newbie complaint.
* Cache ENOSYS (function not implemented) errors on *xattr, flush
and fsync
* Don't call getdir method from open() only from first readdir().
Open is sometimes just used to store the current directory

* Add file locking for mount/unmount (based on patch by Valient
2003-12-11 David McNab <>
* Python filesystem - was broken with python2.3, now fixed:
- changed PyTuple_* calls to PySequence_*, because os.lstat
is no longer returning a pure tuple
- changed PyInt_Check() calls to also call PyLong_Check,
to cover for cases (eg os.lstat) where longs are returned
- Added support for file 'release' handling, which IMO is
essential since this signals to a FS that writes to a file
are complete (and therefore the file can now be disposed of
meaningfully at the python filesystem's discretion)
- Added '__init__' handler to base Fuse class, which allows
your Python class to know the mountpoint and mount args,
as attributes myfs.mountpoint, myfs.optlist, myfs.optdict
* General:
- added 'mount.fuse' script (in util/ dir), which is meant to be
symlinked from /sbin, and which allows FUSE filesystems to
be mounted with the 'mount' command, and listed in fstab;
also, mount arguments get passed to your filesystem
