	* Released 2.7.0

2007-07-02  Miklos Szeredi <[e-mail]>

	* Accept a NULL "op" for fuse_main(), etc.  This is useful if
	filesystem is only invoking fuse to print a help message, or
	version.  Fixes RedHat bugzilla #217343

2007-06-22  Miklos Szeredi <[e-mail]>

	* lib: fix locking when loading a filesystem module

2007-06-21  Miklos Szeredi <[e-mail]>

	* Add fs subtype support to mount.fuse

2007-06-20  Miklos Szeredi <[e-mail]>

	* Add fs subtype support to libfuse and fusermount

2007-06-19  Miklos Szeredi <[e-mail]>

	* kernel: sync with mainline (2.6.22)

2007-06-18  Miklos Szeredi <[e-mail]>

	* Send debug output to stderr instead of stdout.  Patch by Jan
	Engelhardt

2007-06-03  Miklos Szeredi <[e-mail]>

	* libulockmgr: Work around a kernel bug in recv(), causing it to
	sometimes return zero even if data was available on the socket.

2007-05-29  Miklos Szeredi <[e-mail]>

	* lib: optimization: store parent pointer in node instead of
	parent id

2007-05-25  Miklos Szeredi <[e-mail]>

	* lib: don't create new thread for each FORGET request.  FORGET
	messages sometimes caused so many threads to be created, that
	process virtual memory space ran out.  Reported by Chris AtLee

2007-05-24  Miklos Szeredi <[e-mail]>

	* lib: fix memory leak on thread creation failure in multithreaded
	event loop.  Found by Chris AtLee

2007-05-23  Miklos Szeredi <[e-mail]>

	* lowlevel lib: add fuse_reply_iov function, which is similar to
	fuse_reply_buf, but accepts a vector of buffers.  Patch by Roger
	Willcocks

2007-05-21  Miklos Szeredi <[e-mail]>

	* Fix Oops or error if a regular file is created with mknod(2) on
	a fuse filesystem.  Kernels 2.6.18 onward are affected.  Thanks to
	J. Cameijo Cerdeira for the report

2007-05-11  Csaba Henk <[e-mail]>

	* libfuse: fix return value of fuse_loop()/fuse_loop_mt().
	Error reported by Csaba Henk, fix by Miklos Szeredi

2007-05-03  Miklos Szeredi <[e-mail]>

	* Released 2.7.0-rc1

2007-05-02  Miklos Szeredi <[e-mail]>

	* kernel: sync with mainline:

	* Use invalidate_mapping_pages() if available

	* Fix BUG when invalid file type is supplied in mount. Patch by
	Timo Savola

2007-04-27  Miklos Szeredi <[e-mail]>

	* libfuse: call umount(8) directly instead of fusermount if
	possible

	* Clean up init script, make it LSB compliant

2007-04-26  Miklos Szeredi <[e-mail]>

	* In multithreaded loop, use a semaphore instead of SIGHUP to wake
	up the main thread on umount.  This is more elegant, and works
	even if signals are blocked.

2007-04-25  Miklos Szeredi <[e-mail]>

	* Improve mounting support in libfuse:
	 - check non-empty mountpoint
	 - only fall back to fusermount when necessary

2007-04-23  Miklos Szeredi <[e-mail]>

	* Don't chdir to "/" in foreground mode, it causes more trouble
	than it's worth

2007-04-18  Miklos Szeredi <[e-mail]>

	* Replace utils/mount.fuse "sh" script with a "C" program

2007-04-15  Miklos Szeredi <[e-mail]>

	* Add -lulockmgr to compilation comment in fusexmp_fh.c

2007-04-05  Miklos Szeredi <[e-mail]>

	* Check for iconv.  Patch by Csaba Henk

	* Released 2.7.0-pre1

2007-03-05  Miklos Szeredi <[e-mail]>

	* Correctly handle O_APPEND in direct IO mode.  Reported by Greg

	by Thomas Weinbrenner

2007-02-26  Miklos Szeredi <[e-mail]>

	* Fix detection of installed fuse in init script.  Reported and
	fix suggested by Davide Canova

2007-02-05  Miklos Szeredi <[e-mail]>

	* Fix 2.6.9 RHEL kernels, which have compatibility mutex.h, but
	don't define mutex_destroy(), bummer.  Patch from Phil Schwan

2007-02-04  Miklos Szeredi <[e-mail]>

	* Compile fuseblk for kernels which don't have an option to turn
	off the block layer (CONFIG_BLOCK).  Reported by Szakacsits
	Szabolcs

2007-02-03  Miklos Szeredi <[e-mail]>

	* Add filesystem stacking support to high level API.  Filesystem
	modules can be built into libfuse or loaded from shared object
	(.so) files

	* Add 'subdir' and 'iconv' built in modules

	* lib/fuse.c: Fix locking for the reply code in create and open

2007-02-02  Miklos Szeredi <[e-mail]>

	* kernel: make it compile on "strange" kernels which have emulated
	mutexes via <linux/mutex.h> but no i_mutex.  Reported by Tomasz
	Mateja

2007-01-28  Miklos Szeredi <[e-mail]>

	* kernel: fix BUG in control filesystem if it is umounted and
	mounted again, while some fuse filesystems are present.
	Bugreport from Florent Mertens

	* kernel: sync with mainline, support 2.6.20

2007-01-22  Miklos Szeredi <[e-mail]>

	* lib/Makefile.am: actually link libfuse against libfuse_libs

2007-01-19  Miklos Szeredi <[e-mail]>

	* Build fix for 2.6.16 vanila and 2.6.15 FC5 kernels.  Patch from

2007-01-02  Miklos Szeredi <[e-mail]>

	* Fix unaligned access in file desctriptor passing in libfuse,
	fusermount and ulockmgr.  Debian bug ID: 404904.  Reported and
	tested by Sebastian Fontius

2006-12-16  Miklos Szeredi <[e-mail]>

	* kernel: don't keep unreferenced inodes in the icache.

2006-12-15  Miklos Szeredi <[e-mail]>

	* fusermount: Fix detection of fuseblk.  Reported by Szakacsits
	Szabolcs

	* lib: Fix use after free in fuse_flush().  Reported by Ron
	Lindman

2006-12-10  Miklos Szeredi <[e-mail]>

	* mount.fuse: add "setuid=USER" option which does a "su - USER"
	for the filesystem

	* fusermount: use "/bin/mount -f" to add entry to /etc/mtab, and
	"/bin/umount" to remove entry from /etc/mtab.  This gets rid of
	the ugly code dealing with mtab, as well as a possible race
	between fusermount and mount trying to modify /etc/mtab at the
	same time

	* Fix "buffer size too small: 4" warning for users of the
	fuse_loop_mt_proc() function.

2006-12-04  Miklos Szeredi <[e-mail]>

	* Fix warnings with gcc-4.1 on 64bit archs.  Report from
	Harshavardhana

	* Add extra warning options, and fix resulting warnings

	* Really fix fuse_teardown problem

2006-12-02  Miklos Szeredi <[e-mail]>

	* Add -lrt to fuse.pc (if needed) to fix static linking against
	libfuse.  Reported by Szakacsits Szabolcs

2006-12-01  Miklos Szeredi <[e-mail]>

	* Released 2.6.1

2006-11-30  Miklos Szeredi <[e-mail]>

	* Fix API version 21 and 22 compatibility for fuse_teardown.
	Reported by Bgs

2006-11-29  Miklos Szeredi <[e-mail]>

	* fusermount: Print a more helpful message in case the kernel
	doesn't support the 'fuseblk' filesystem type.  This has been
	biting ntfs-3g users.  Reported by Yura Pakhuchiy

	* kernel: fix build problem for "make -C ...".  Reported by
	Stephen Bryant

2006-11-19  Miklos Szeredi <[e-mail]>

	* Fix bug in certain error paths of lookup routines.  The request
	object was reused for sending FORGET, which is illegal.  This bug
	could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
	silently corrupt memory in earlier versions.  Report and test
	program by Russ Cox

2006-11-11  Miklos Szeredi <[e-mail]>

	* Print an error if an incompatible kernel interface version is
	detected in INIT.  This will only show if filesystem is started
	with -d or -f

	* Fix order of fuse_destroy()/fuse_unmount() in error cleanup of
	fuse_setup_common().  Reported by Szakacsits Szabolcs

2006-11-06  Miklos Szeredi <[e-mail]>

	* Fix recursive locking in fuse_create().  Thanks to Takuya
	Ishibashi for the bug report

2006-10-28  Miklos Szeredi <[e-mail]>

	* Fix automake problem.  Patch from Nix

2006-10-26  Miklos Szeredi <[e-mail]>

	* Fix mount.fuse to use /bin/sh instead of /bin/bash, which is not
	always available on embedded systems.  Patch from Paul Smith

	* Fix util/Makefile.am, so that failure to run update-rc.d or
	device creation doesn't cause make to fail.  Reported by Paul
	Smith

2006-10-21  Miklos Szeredi <[e-mail]>

	* Released 2.6.0

2006-10-18  Miklos Szeredi <[e-mail]>

	* fusermount: don't try to create a lock file if /etc/mtab is a
	symlink.  Report and patch from Alexei Sheplyakov (debian bug
	#393693)

2006-10-17  Miklos Szeredi <[e-mail]>

	* Minor changes, sync with mainline tree

2006-10-16  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-rc3

2006-10-15  Miklos Szeredi <[e-mail]>

	* kernel: cleanups

2006-10-13  Miklos Szeredi <[e-mail]>

	* kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
	Report from David Shaw

	* lib: Fix lost error on renaming a file. Report from David Shaw

	* lib: Fix lost error on hiding open files (renaming to
	.fuse_hiddenXXXX)

	* kernel: Fix a rare hang on SMP/32bit on heavy filesystem
	activity.  The cause of the bug was that some calls to
	i_size_write() were not protected by a lock, and hence
	i_size_seqcount could become corrupted.  This caused subsequent
	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
	related to NFS exporting (it's not).  It was reported by various
	people, but Dana Henriksen has finally helped me to track it down,
	so big thanks to him

	* kernel: Protect against truncation of a swapfile

2006-10-10  Miklos Szeredi <[e-mail]>

	* kernel: Check for signature of super_operations->umount_begin().
	Ubuntu kernel 2.6.17 seems to use the new signature found in
	2.6.18.  Thanks to Florent Mertens for the report

2006-10-08  Miklos Szeredi <[e-mail]>

	* 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/Makefile.am

	* 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 <[e-mail]>

	* Released 2.6.0-rc2

2006-10-01  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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
	release

	* In fuse_dentry_revalidate() use dget_parent() instead of
