Linux下fuse用户文件系统的的源代码

2005-11-27  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* Add detection of mainline FUSE code in running kernel

2005-11-21  Miklos Szeredi <[e-mail]>

	* Don't use async cancelation in multithreaded loop.  This makes
	it more portable to systems where read() is not async cancel safe.
	Report from Andriy Gapon

2005-11-20  Miklos Szeredi <[e-mail]>

	* Warn if API version 11 compatibility is requested

2005-11-17  Miklos Szeredi <[e-mail]>

	* More FreeBSD merge

	* fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
	them, because it corrupts /etc/mtab.  Found by Thomas Biege
	CVE-2005-3531

	* libfuse: don't use system() to invoke 'fusermount -u ...'
	because it breaks mountpoints with spaces in them into multiple
	arguments

2005-11-16  Miklos Szeredi <[e-mail]>

	* Merge library part of FreeBSD port.  Patch by Csaba Henk

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

	* Use 64bit type for file handle, so the full range supported by
	the kernel interface is available to applications

2005-11-10  Miklos Szeredi <[e-mail]>

	* Moved mountpoint argument checking from fuse_parse_cmdline() to
	fuse_mount() in preparation to FreeBSD merge.

2005-11-08  Miklos Szeredi <[e-mail]>

	* Remove unneeded close() from fuse_teardown().  Spotted by Csaba
	Henk.

2005-11-07  Miklos Szeredi <[e-mail]>

	* Make the statfs change backwards compatible.

2005-11-06  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* Add fgetattr() method, which currently will only be called after
	a successful call to a create() method.

2005-10-26  Miklos Szeredi <[e-mail]>

	* 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.*

	* Add atomic CREATE+OPEN operation.  This will only work with
	2.6.15 (presumably) or later Linux kernels.

	* Add ftruncate() method.  This will only work with 2.6.15
	(presumably) or later Linux kernels.

	* Fix kernel module compile if kernel source and build directories
	differ.  Report and initial patch by John Eastman

2005-10-18  Miklos Szeredi <[e-mail]>

	* lib: optimize buffer reallocation in fill_dir.

2005-10-17  Miklos Szeredi <[e-mail]>

	* Released 2.4.1

2005-10-14  Miklos Szeredi <[e-mail]>

	* libfuse: add debug for write result (by Shaun Jackman) and
	warnings for too large read/write result

2005-10-11  Miklos Szeredi <[e-mail]>

	* Spelling fixes, thanks to Ioannis Barkas

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

	* fuse_common.h: use extern "C".  Thanks to Valient Gough for the
	patch

2005-10-07  Miklos Szeredi <[e-mail]>

	* highlevel-lib: init() and destroy() methods didn't have an
	initialized fuse_context.  Bug reported by Tim Stoakes

2005-10-04  Miklos Szeredi <[e-mail]>

	* Released 2.4.0

2005-10-03  Miklos Szeredi <[e-mail]>

	* Add documentation to fuse_lowlevel.h

	* API cleanups:

	* Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME

	* Move fuse_mount() and fuse_unmount() to fuse_common.h

	* Change the return type of fuse_reply_none() from int to void.

2005-09-30  Miklos Szeredi <[e-mail]>

	Report by Balázs Pozsár

2005-09-28  Miklos Szeredi <[e-mail]>

	* UClibc fixes from Christian Magnusson

2005-09-27  Miklos Szeredi <[e-mail]>

2005-09-26  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-rc1

2005-09-26  Miklos Szeredi <[e-mail]>

	* fusermount: allow user umount in the case when /etc/mtab is a
	symlink to /proc/mounts.  Reported by Balázs Pozsár.

2005-09-23  Miklos Szeredi <[e-mail]>

	* Check for special node ID values in lookup and creation

2005-09-22  Miklos Szeredi <[e-mail]>

	* Slight optimization in returning EINVAL error in case of an open
	with O_DIRECT flag.

2005-09-20  Miklos Szeredi <[e-mail]>

	* Remove '--enable-auto-modprobe' configure flag.  Module
	auto-loading is now handled by the kernel.

2005-09-15  Miklos Szeredi <[e-mail]>

	* Install UDEV rule file, so /dev/fuse is created with mode 0666.
	Help from Jens M. Noedler.

2005-09-14  Miklos Szeredi <[e-mail]>

	* Add memory cleanup on thread exit

2005-09-13  Miklos Szeredi <[e-mail]>

	* Set umask to zero in fusexmp and fusexmp_fh, so that
	files/directories are created with the requested mode.

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

	* Don't ignore read error in multithreaded loop

2005-09-08  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-pre2

2005-09-08  Miklos Szeredi <[e-mail]>

	* Revert lock and access operations.  Postpone these until 2.5.

2005-09-02  Miklos Szeredi <[e-mail]>

	* Fix compile warning on 2.6.13 and later

	* Fix compilation on old kernels

2005-08-19  Miklos Szeredi <[e-mail]>

	* lib: always refresh directory contents after rewinddir() to
	conform to SUS.  Bug found by John Muir.

2005-08-15  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-pre1

2005-08-14  Miklos Szeredi <[e-mail]>

	* lib: cleaned up (or messed up, depending on your POV) the low
	level library API.  Hopefully this is close to the final form.

2005-08-05  Miklos Szeredi <[e-mail]>

	* fusermount: don't allow empty mountpoint argument, which defeats
	automatic umounting in fuse_main().  Bugreport by Václav Jůza

2005-08-03  Miklos Szeredi <[e-mail]>

	* fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
	option is used (Paul Alfille).

2005-08-02  Miklos Szeredi <[e-mail]>

	* 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
	second.

	* kernel: correctly handle zero timeout for attributes and entries

2005-08-01  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* kernel: invalidate attributes for read/readdir/readlink
	operations

	* kernel: detect newer UML kernels

2005-07-26  Miklos Szeredi <[e-mail]>

	* Make the installation path of fuse.ko and mount.fuse
	configurable through INSTALL_MOD_PATH and MOUNT_FUSE_PATH
	environment variables.  Requirement and help from Csaba Henk.

2005-07-22  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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
	Magnusson

	* 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 <[e-mail]>

	* fusermount: add '-v', '--version' and '--help' options

	* add inode based API

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

	* lib: don't block signals in worker threads.  Problem noticed by
	Usarin Heininga

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

	* lib: don't allow both 'allow_other' and 'allow_root' options to
	be given

2005-07-06  Miklos Szeredi <[e-mail]>

	* 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'

2005-07-03  Miklos Szeredi <[e-mail]>

	* kernel: clean up 'direct_io' code

2005-06-28  Miklos Szeredi <[e-mail]>

	* Add 'mount.fuse' written by Petr Klima

	* '/dev/fuse' is created by 'make install' if does not yet exist

2005-06-20  Miklos Szeredi <[e-mail]>

	* Fix UCLIBC compile error.  Patch by Christian Magnusson

2005-06-08  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* Released 2.3.0

2005-06-02  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* Released 2.3-rc1

2005-05-12  Miklos Szeredi <[e-mail]>

	* 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 <[e-mail]>

	* 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 <[e-mail]>

	* Released 2.3-pre7

2005-05-08  Miklos Szeredi <[e-mail]>

	* 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
	compatible.

2005-05-06  Miklos Szeredi <[e-mail]>

	* Fix abort for out of order FORGET messages.  Again.  Spotted by
	Franco Broi again.  Sorry :)

2005-04-29  Miklos Szeredi <[e-mail]>

	* Released 2.3-pre6

2005-04-29  Miklos Szeredi <[e-mail]>

	* Make fusermount work with fuse kernel modules not yet supporting
	the "group_id" option (added for the purpose of stricter
	permission checking).
