Linux下fuse用户文件系统的的源代码

	Bug found and patch tested by Mark Huijgen

2006-07-05  Miklos Szeredi <[e-mail]>

	* fusermount: if /dev/fuse doesn't exist, suggest modprobing fuse;
	this makes sense on systems using udev.  Reported by Szakacsits
	Szabolcs

2006-06-29  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-pre3

2006-06-29  Miklos Szeredi <[e-mail]>

	* Support in kernel module for file locking and interruption.  The
	same functionality is available in official kernels >= 2.6.18

2006-06-28  Miklos Szeredi <[e-mail]>

	* Add POSIX file locking support

	* Add request interruption

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

	* Add missing pthread_rwlock_destroy().  Patch from Remy Blank

2006-06-05  Remy Blank <[e-mail]>

	* lib: canonicalize mount point in fuse_helper_opt_proc() so that
	unmounting succeeds even if mount point was relative.

2006-06-04  Csaba Henk <[e-mail]>

	* lib: fix emergency umount in helper.c when malloc fails.
	(The way it was done would end up in a segfault.)

2006-06-01  Csaba Henk <[e-mail]>

	* lib: adjust threading related compiler flags.
	Switch to "-pthread" from "-lpthread" as that's the preferred
	one on several platforms. Consulted with Terrence Cole and
	Miklos Szeredi

2006-05-08  Miklos Szeredi <[e-mail]>

	* lib: search fusermount in installation directory (bindir) as
	well as in PATH.

2006-05-03  Miklos Szeredi <[e-mail]>

	* lib: fix compilation if CLOCK_MONOTONIC is not defined.
	Reported by Christian Magnusson

2006-04-23  Csaba Henk <[e-mail]>

	* lib: make FreeBSD mount routine recognize if kernel features
        backgrounded init and if it does, run the mount util in foreground
        (similarly to Linux)

2006-04-21  Miklos Szeredi <[e-mail]>

	* kernel: fix fput deadlock fix, the lockless solution could lead
	to "VFS: busy inodes after umount..."

	* kernel: fix race between checking and setting file->private_data
	for the device.  Found by Al Viro

2006-04-11  Miklos Szeredi <[e-mail]>

	* kernel: remove request pool, instead allocate requests on
	demand.  Account the number of background requests, and if they go
	over a limit, block the allocation of new requests.

	* kernel: fix deadlock if backgrounded request holds the last
	reference to the super block

	* kernel: don't use fuse_reset_request() during direct I/O

2006-04-06  Csaba Henk <[e-mail]>

	* lib: Let FreeBSD mount option parsing routine recognize "no"
	prefixes for FUSE specific options as well

2006-04-01  Miklos Szeredi <[e-mail]>

	* lib: Add missing rwlock initialization.  Patch by Ryan Bradetich

2006-03-17  Miklos Szeredi <[e-mail]>

	* API changes:

	* fuse_main(), fuse_setup() and fuse_new() have an additionl
	user_data parameter

	* fuse_mount() returns a 'struct fuse_chan' pointer instead of a
	file descriptor

	* fuse_unmount() receives a 'struct fuse_chan' pointer.  It
	destroys the given channel

	* fuse_teardown() no longer has a file descriptor parameter

	* new exported functions: fuse_session_remove_chan(),
	fuse_get_session(), fuse_daemonize()

	* fuse_chan_recv() may now return a new channel which will be used
	to send the reply

2006-03-16  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-pre2

2006-03-16  Miklos Szeredi <[e-mail]>

	* Don't unmount if already unmounted.  This fixes a problem seen
	in the following situation: Lazy unmount a busy filesystem; Mount
	a new one in top; When the first finally unmounts, the second also
	unmounts.  Reported by Franco Broi

2006-03-15  Miklos Szeredi <[e-mail]>

	* lowlevel lib: use indirect function calls instead of a
	switch/case construct.  Besides increased efficiency it helps
	maintainability & readability too.  Patch from Florin Malita

2006-03-13  Miklos Szeredi <[e-mail]>

	* kernel: replace global spinlock with a per-connection spinlock

2006-03-10  Miklos Szeredi <[e-mail]>

	* Fix source compatibility breakage for fuse_unmount().  Report
	from Yura Pakhuchiy

2006-03-02  Miklos Szeredi <[e-mail]>

	* Fix O_ASYNC handling in fuse_dev_release().  From Jeff Dike

2006-03-01  Miklos Szeredi <[e-mail]>

	* Add O_ASYNC and O_NONBLOCK support to FUSE device.  Patch by
	Jeff Dike

	* Renamed fuse_chan_receive() to fuse_chan_recv() and changed
	interface to return -errno in case of error.

2006-03-01  Csaba Henk <[e-mail]>

	* libfuse: pass device file descriptor to fuse_unmount(), rewrite
	FreeBSD implementation so that it uses libc (sysctl backed) instead
	of an embdedded script (kmem backed). Adjust the control flow of
	hello_ll so that device doesn't get closed before unmount attempt.

2006-02-25  Miklos Szeredi <[e-mail]>

	* Lowlevel lib: return all-zero statvfs data if filesystem doesn't
	implement method.  This is needed on FreeBSD, and nicer on Linux
	too.  Highlevel lib already did this.  Reported by Csaba Henk

	* Fix negative entry handling.  There was a bug, that negative
	lookups with timeouts (nodeid == 0) returned -EIO.

2006-02-23  Miklos Szeredi <[e-mail]>

	* Fix race between RELEASE and UNLINK, which might leave
	.fuse_hidden* files around

2006-02-21  Miklos Szeredi <[e-mail]>

	* fusexmp_fh: implement flush() method and call close() on the
	open file descriptor.  This is needed if used on an NFS
	filesystem, which buffers data until file is closed.  Franco Broi
	spotted the situation when 'cp -p' failed to set the modification
	time because of this.

2006-02-20  Miklos Szeredi <[e-mail]>

	* Released 2.6.0-pre1

2006-02-19  Miklos Szeredi <[e-mail]>

	* libfuse: fix use-after-free bug in interruptred reply_entry().
	Patch from John Muir

	* libfuse: fix wrong symbol versioning for fuse_mount.  Debian bug
	ID: 352631.  Found by Stéphane Rosi

2006-02-17  Miklos Szeredi <[e-mail]>

	* Lowlevel lib: Unify fuse_dirent_size() and fuse_add_dirent()
	into a single function fuse_add_direntry().  This cleans up the
	interface and makes it possible to do stacking.

2006-02-16  Miklos Szeredi <[e-mail]>

	* Fix rare race betweeen abort and release caused by failed iget()
	in fuse_create_open().

	* Add 'ac_attr_timeout' option e.g. for filesystems which do their
	own attribute caching.

2006-02-15  Miklos Szeredi <[e-mail]>

	* Work around FreeBSD runtime linker "feature" which binds an old
	version of a symbol to internal references if the symbol has more
	than one version.  This resulted in infinite recursion in
	fuse_lowlevel_new_compat25().

2006-02-10  Csaba Henk <[e-mail]>

	* Refine clock_gettime() querying so that linker options
	shall be set as it's appropriate for the target platform.

2006-02-09  Miklos Szeredi <[e-mail]>

	* Fix udev rule syntax.  Reported by Nix

2006-02-08  Miklos Szeredi <[e-mail]>

	* In some cases udev rule seems to be ineffective when installed
	as 40-fuse.rules but work as 60-fuse.rules.  Reported by John Hunt

2006-02-03  Miklos Szeredi <[e-mail]>

	* Fix compilation when build directory is different from source
	directory.  Reported by Frédéric L. W. Meunier

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

	* Fix even bigger bug introduced in fix for request_end() on
	2006-01-14.  Reported by Gal Rosen

2006-01-30  Miklos Szeredi <[e-mail]>

	* highlevel-lib: add 'auto_cache' option.  This caches file data
	based on modification time and size

2006-01-20  Miklos Szeredi <[e-mail]>

	* Sanitize storage type and help message in mount_bsd.c.  Patch
	from Csaba Henk

	* fuse_opt: add new helper constants FUSE_OPT_KEY_KEEP and
	FUSE_OPT_KEY_DISCARD

	* Add options 'max_readahead', 'sync_read' and 'async_read'

	* Kernel ABI version 7.6:

	* Negotiate the 'max_readahead' value and 'async_read' flags with
	userspace in the INIT method

	* Add connection info to ->init() methods to both lowlevel and
	highlevel API

	* Fall back to synchronous read() behavior if either library or
	userspace filesystem is using the old interface version.  This is
	needed so non-updated filesystems won't be confused by the
	different read() behavior

2006-01-19  Miklos Szeredi <[e-mail]>

	* lib: if "fsname=" option was given, pass it to fusermount

	* fuse_opt: add new fuse_opt_insert_arg() function, which is
	needed by filesystems to implement some argument manipulations
	correctly

	* fuse_opt: fix memory leak in handling "--" option

2006-01-18  Miklos Szeredi <[e-mail]>

	* kernel: fix detection of case when fuse is not configured into
	the kernel either as module or built-in

	* fuse_opt.h: fix incompatibility with C++ compilers by renaming
	'template' structure member to 'templ'.  Reported by Takashi Iwai

	* fuse.h: fix compatibility bugs.  Patch by Yura Pakhuchiy

	* kernel: support version 2.6.16 (i_sem -> i_mutex)

2006-01-16  Miklos Szeredi <[e-mail]>

	* Added (again) asynchronous readpages support

	* Each connection now shows up under /sys/fs/fuse/connections

	* Connection attributes exported to sysfs: 'waiting' number of
	waiting requests; 'abort' abort the connection

	* Connection may be aborted through either the sysfs interface or
	with 'umount -f mountpoint'

2006-01-14  Miklos Szeredi <[e-mail]>

	* Released 2.5.0

2006-01-14  Miklos Szeredi <[e-mail]>

	* kernel: fix a couple of bugs

	* Order of request_end() and fuse_copy_finish() was wrong.
	Posthumous note: Franco Broi managed to exploit this, though it
	seemed quite impossible

	* request_end() used request pointer after decrementing refcount

	* Clearing ->connected or ->mounted connection flags could race
	with setting other bitfields not protected with a lock

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

	* kernel: add necessary compile flags for 2.4.X/x86_64.
	Report from Sean Ziegeler

2006-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.5.0-pre2

2006-01-09  Miklos Szeredi <[e-mail]>

	* Applied patch from Csaba Henk, to update mount_bsd to new
	fuse_mount() semantics

	* Ignore auto,noauto,... options in mount.fuse.  Reported by Frank
	Steiner and Don Taber

	* fusermount: add 'dirsync' mount option

2006-01-07  Miklos Szeredi <[e-mail]>

	* Improved help reporting and added version reporting to library

2006-01-06  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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

2005-12-16  Miklos Szeredi <[e-mail]>

	* Clean up the option parsing interface slightly, by creating an
	"argument list" structure, that contains the argument vector and
	count

2005-12-15  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* Fix readdir() failure on x86_64, of 32bit programs compiled
	without largefile support.  Bug report and help from Anthony
	Kolasny

	* If lookup returns invalid mode, return -EIO instead of creating
	a regular file

	* Add current output argument vector to option processing
	function

2005-12-12  Miklos Szeredi <[e-mail]>

	* Fix stale code in ifdef FreeBSD.  Patch from Csaba Henk

2005-12-09  Miklos Szeredi <[e-mail]>

	* Released 2.5.0-pre1

2005-12-09  Miklos Szeredi <[e-mail]>

	* libfuse: added option parsing interface, defined in
	<fuse_opt.h>.

2005-12-07  Miklos Szeredi <[e-mail]>

	* Return EIO for file operations (read, write, fsync, flush) on
	open files whose inode has become "bad".  Inodes will be marked
	"bad" if their type changes.  Bug report by Csaba Henk

2005-12-06  Miklos Szeredi <[e-mail]>

	* Use bigger request buffer size.  write() did not work on archs
	with > 4k page size, Bug report by Mark Haney

	* ABI version 7.5:

	* Extend INIT reply with data size limits

2005-12-02  Miklos Szeredi <[e-mail]>

	* Fix memory leak in fuse_read_cmd()/fuse_process_cmd().  Bug
	reported by Vincenzo Ciancia

	* Handle exit-by-umount in fuse_read_cmd()

2005-11-29  Miklos Szeredi <[e-mail]>

	* Check if '-msoft-float' option is supported by compiler when
	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 <[e-mail]>

	* Fix bug in 32-bit file handle compatibility
