Linux下fuse用户文件系统的的源代码

2005-04-28  Miklos Szeredi <[e-mail]>

	* 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.

2005-04-23  Miklos Szeredi <[e-mail]>

	* Released 2.3-pre5

2005-04-22  Miklos Szeredi <[e-mail]>

	* Add -msoft-float to kernel module compile flags for 2.4.X.  This
	is needed on certain architectures.  Report from Chris Kirby

	* Fix buggy behavior of open(..., O_CREAT|O_EXCL) if interrupted.
	Reported by David Shaw

	* Remove "allow_root" option from kernel module, and implement
	it's functionality in the library

	* Fix Oops caused by premature release of fuse_conn.  Clean up
	related code, to be more readable

	* Sendfile should not use page cache if "direct_io" mount option
	is given

2005-04-08  Miklos Szeredi <[e-mail]>

	* Fix Oops in case of nfs export.  Spotted by David Shaw

	* Fix another Oops in case of write over nfs with direct_io turned
	on.  Again spotted by David Shaw

2005-03-31  Miklos Szeredi <[e-mail]>

	* Released 2.3-pre1

2005-03-31  Miklos Szeredi <[e-mail]>

	* kernel API: add padding to structures, so 64bit and 32bit
	compiler will return the same size

	* kernel API: add offset field to fuse_dirent.  This will allow
	more sophisticated readdir interface for userspace

	* kernel API: change major number to 6

	quirk

	* lib: don't exit threads, so cancelation doesn't cause segfault

2005-03-04  Miklos Szeredi <[e-mail]>

	* kernel: fix nasty bug which could cause an Oops under certain
	situations.  Found by Magnus Johansson

2005-02-28  Miklos Szeredi <[e-mail]>

	* libfuse: added opendir() method.  This can be used in case
	permission checking in getdir() is too late.  Thanks to Usarin
	Heininga for pointing out this deficiency

	* libfuse: added init() and destroy() methods to fuse_operations

	* kernel: llseek() method for files and directories made explicit

	* kernel: fixed inode leak in NFS export in case of nodeid
	wrapping

2005-02-15  Miklos Szeredi <[e-mail]>

	* libfuse: clean up some unitialized memory found with valgrind

	* Add -lpthread to Libs in fuse.pc.  Valgrind seems to need an
	explicitly linked libpthread for applications

2005-02-10  Miklos Szeredi <[e-mail]>

	* fusermount: set umask, otherwise /etc/mtab will have
	unpredictable permission.  Spotted by Jindrich Kolorenc

	* fusermount: set owner and group of /etc/mtab to original values
	on unmount

	* libfuse: add 'use_ino' option to help.  Patch by Valient Gough

2005-02-07  Miklos Szeredi <[e-mail]>

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

	* Released 2.2

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

2005-01-28  Miklos Szeredi <[e-mail]>

	* Fix compilation on 2.6.7

2005-01-26  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre6

2005-01-26  Miklos Szeredi <[e-mail]>

	passed as the first argument.  Found by Anton Altaparmakov

2005-01-21  Miklos Szeredi <[e-mail]>

	* LIB: fix double reply in readdir operation

	* fusermount: fix uid checking bug.  Patch by Adam Connell

	a bug on Progeny 2.4.20 kernel).  Reported by Valient Gough

2005-01-20  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)

2005-01-18  Miklos Szeredi <[e-mail]>

	* KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
	and RELEASEDIR.  This ends the ugly hack of passing a file
	descriptor to the kernel, and actually makes the code simpler.

2005-01-17  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre4

2005-01-17  Miklos Szeredi <[e-mail]>

	* fusermount: remove capability setting, which was the cause of
	problems for some users.  It seems that FS related capabilities
	are removed by setfsuid(), so this isn't even needed.

2005-01-15  Miklos Szeredi <[e-mail]>

	* fix compilation on 2.4 kernels (reported by Valient Gough)

	* fix failure to unmount bug (found by David Shaw)

	* fusermount: improve parsing of /etc/fuse.conf

2005-01-13  Miklos Szeredi <[e-mail]>

	are now checked by fusermount, and can be set in /etc/fuse.conf

	* KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)

2005-01-11  Miklos Szeredi <[e-mail]>

	* KERNEL: fix possible inode allocation problem, where
	sizeof(struct inode) is not aligned (found by Mike Waychison)

	* KERNEL: use new follow_link/put_link methods

	* KERNEL: cosmetic fixes

2005-01-10  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre3

2005-01-10  Miklos Szeredi <[e-mail]>

	* Add missing code that was accidently left out

2005-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre2

2005-01-09  Miklos Szeredi <[e-mail]>

	* Change "uid" mount option to "user_id" to avoid confusion with a
	mount option "uid" commonly used by many filesystems

2005-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.2-pre1

2005-01-09  Miklos Szeredi <[e-mail]>

	* If FUSE is configured in the kernel, don't build it by default

2005-01-07  Miklos Szeredi <[e-mail]>

	* Compile fix by Christian Magnusson

2005-01-05  Miklos Szeredi <[e-mail]>

	* Fix compilation for 2.6.{0-5} kernels

2005-01-04  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* KERNEL: invalidate dentry/attributes if interrupted request
	could leave filesystem in an unknown state.

2004-12-12  Miklos Szeredi <[e-mail]>

	* 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.

2004-12-10  Miklos Szeredi <[e-mail]>

	* When mounting on a subdirectory of / don't duplicate slashes at
	the beggining of path (spotted by David Shaw)

2004-12-09  Miklos Szeredi <[e-mail]>

	* Fix bug causing garbage in mount options (spotted by David Shaw)

2004-12-07  Miklos Szeredi <[e-mail]>

	* Add 'writepage' flag to 'fuse_file_info'.

	* More comments in fuse.h

	* Get rid of double underscores

2004-12-04  Miklos Szeredi <[e-mail]>

	* Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config

	* helper.c: add -ho option, which only displays the options not
	the usage header.  This can be used by filesystems which have
	their own options.

2004-12-03  Miklos Szeredi <[e-mail]>

	* Add source compatibility to 2.1 and 1.1 APIs.  To select betwen
	versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
	including the fuse header

	* Add binary compatibility to 2.1 version of library with symbol
	versioning

2004-12-03  Miklos Szeredi <[e-mail]>

	* Released 2.1

2004-12-01  Miklos Szeredi <[e-mail]>

	* kernel: clean up writing functions

	* kernel: no allocation on write in direct_io mode

	* move linux/fuse.h to fuse_kernel.h

2004-11-30  Miklos Szeredi <[e-mail]>

	* kernel: clean up reading functions

2004-11-29  Miklos Szeredi <[e-mail]>

	* 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
	exists

	* 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 <[e-mail]>

	* 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
	3.0.

2004-11-23  Miklos Szeredi <[e-mail]>

	* More cleanups in the kernel

	* The 10,229 charater device number has been assigned for FUSE

	* Version file checking fix (reported by Christian Magnusson)

	* fusermount: opening the fuse device now doesn't need /sys.

	* Optimize reading by controlling the maximum readahead based on
	the 'max_read' mount option

	* fixes for UCLIBC (Christian Magnusson)

2004-11-19  Miklos Szeredi <[e-mail]>

	* Cleaned up kernel in preparation for merge into mainline:
