2006-02-16 Miklos Szeredi * 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 * 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 * Refine clock_gettime() querying so that linker options shall be set as it's appropriate for the target platform. 2006-02-09 Miklos Szeredi * Fix udev rule syntax. Reported by Nix 2006-02-08 Miklos Szeredi * 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 * Fix compilation when build directory is different from source directory. Reported by Frédéric L. W. Meunier 2006-02-02 Miklos Szeredi * Fix even bigger bug introduced in fix for request_end() on 2006-01-14. Reported by Gal Rosen 2006-01-30 Miklos Szeredi * highlevel-lib: add 'auto_cache' option. This caches file data based on modification time and size 2006-01-20 Miklos Szeredi * 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 * 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 * 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 * 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 * Released 2.5.0 2006-01-14 Miklos Szeredi * 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 * kernel: add necessary compile flags for 2.4.X/x86_64. Report from Sean Ziegeler 2006-01-09 Miklos Szeredi * Released 2.5.0-pre2 2006-01-09 Miklos Szeredi * 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 * 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 2005-12-16 Miklos Szeredi * 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 * 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 * 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 * Fix stale code in ifdef FreeBSD. Patch from Csaba Henk 2005-12-09 Miklos Szeredi * Released 2.5.0-pre1 2005-12-09 Miklos Szeredi * libfuse: added option parsing interface, defined in . 2005-12-07 Miklos Szeredi * 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 * 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 * 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 * 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 * 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 * 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 * Warn if API version 11 compatibility is requested 2005-11-17 Miklos Szeredi * 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 * Merge library part of FreeBSD port. Patch by Csaba Henk 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 * Remove unneeded close() from fuse_teardown(). Spotted by Csaba Henk. 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.* * 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 * lib: optimize buffer reallocation in fill_dir. 2005-10-17 Miklos Szeredi * Released 2.4.1 2005-10-14 Miklos Szeredi * libfuse: add debug for write result (by Shaun Jackman) and warnings for too large read/write result 2005-10-11 Miklos Szeredi * Spelling fixes, thanks to Ioannis Barkas 2005-10-10 Miklos Szeredi * fuse_common.h: use extern "C". Thanks to Valient Gough for the patch 2005-10-07 Miklos Szeredi * highlevel-lib: init() and destroy() methods didn't have an initialized fuse_context. Bug reported by Tim Stoakes 2005-10-04 Miklos Szeredi * Released 2.4.0 2005-10-03 Miklos Szeredi * 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 * kernel: NFS exporting leaked dentries. Bug found and fixed by Akshat Aranya. 2005-09-29 Miklos Szeredi * fusermount: fix error message, when unable to open /dev/fuse. Report by Balázs Pozsár 2005-09-28 Miklos Szeredi * UClibc fixes from Christian Magnusson 2005-09-27 Miklos Szeredi * Added NAME="%k" to util/udev.rules. Fix by Mattias Wadman. 2005-09-26 Miklos Szeredi * Released 2.4.0-rc1 2005-09-26 Miklos Szeredi * 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 * Check for special node ID values in lookup and creation 2005-09-22 Miklos Szeredi * Slight optimization in returning EINVAL error in case of an open with O_DIRECT flag. 2005-09-20 Miklos Szeredi * Remove '--enable-auto-modprobe' configure flag. Module auto-loading is now handled by the kernel. 2005-09-15 Miklos Szeredi * Install UDEV rule file, so /dev/fuse is created with mode 0666. Help from Jens M. Noedler. 2005-09-14 Miklos Szeredi * Add memory cleanup on thread exit 2005-09-13 Miklos Szeredi * Set umask to zero in fusexmp and fusexmp_fh, so that files/directories are created with the requested mode. 2005-09-12 Miklos Szeredi * Don't ignore read error in multithreaded loop 2005-09-08 Miklos Szeredi * Released 2.4.0-pre2 2005-09-08 Miklos Szeredi * Revert lock and access operations. Postpone these until 2.5. 2005-09-02 Miklos Szeredi * Fix compile warning on 2.6.13 and later * Fix compilation on old kernels 2005-08-19 Miklos Szeredi * lib: always refresh directory contents after rewinddir() to conform to SUS. Bug found by John Muir. 2005-08-15 Miklos Szeredi * Released 2.4.0-pre1 2005-08-14 Miklos Szeredi * 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 * fusermount: don't allow empty mountpoint argument, which defeats 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 second. * 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 * kernel: invalidate attributes for read/readdir/readlink operations * kernel: detect newer UML kernels 2005-07-26 Miklos Szeredi * 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 * 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 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 * fusermount: add '-v', '--version' and '--help' options * add inode based API 2005-07-12 Miklos Szeredi * lib: don't block signals in worker threads. Problem noticed by Usarin Heininga 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' 2005-07-03 Miklos Szeredi * kernel: clean up 'direct_io' code 2005-06-28 Miklos Szeredi * Add 'mount.fuse' written by Petr Klima * '/dev/fuse' is created by 'make install' if does not yet exist 2005-06-20 Miklos Szeredi * Fix UCLIBC compile error. Patch by Christian Magnusson 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 compatible. 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. 2005-04-23 Miklos Szeredi * Released 2.3-pre5 2005-04-22 Miklos Szeredi * 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 * 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 2005-04-07 Miklos Szeredi * Released 2.3-pre4 2005-04-07 Miklos Szeredi * lib: finalized new readdir() interface, which now supersedes the getdir() method. 2005-04-03 Miklos Szeredi * Released 2.3-pre3 2005-04-03 Miklos Szeredi * Implement backward compatibility with version 5 kernel ABI 2005-04-01 Miklos Szeredi * Released 2.3-pre2 2005-04-01 Miklos Szeredi * kernel: fix dirent offset handling * lib: add readdir and releasedir methods * lib: use fh field of fuse_file_info in opendir, readdir, releasedir and fsyncdir methods * lib: check kernel API version and bail out of it's old. This will be properly fixed in the next release 2005-03-31 Miklos Szeredi * Released 2.3-pre1 2005-03-31 Miklos Szeredi * 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 * kernel: fix warnings on 64bit archs * kernel: in case of API version mismatch, return ECONNREFUSED 2005-03-24 Miklos Szeredi * kernel: trivial cleanups 2005-03-21 Miklos Szeredi * Add fsyncdir() operation 2005-03-19 Miklos Szeredi * kernel: add locking to background list (fixes previous fix) 2005-03-18 Miklos Szeredi * kernel: fix bug which could cause leave busy inodes after unmount, and Oops. 2005-03-08 Miklos Szeredi * examples: add -lpthread to link flags to work around valgrind quirk * lib: don't exit threads, so cancelation doesn't cause segfault 2005-03-04 Miklos Szeredi * kernel: fix nasty bug which could cause an Oops under certain situations. Found by Magnus Johansson 2005-02-28 Miklos Szeredi * 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 * 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 * 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 * Cleaned up directory reading (temporary file is not used) 2005-02-02 Miklos Szeredi * Released 2.2 2005-02-02 Miklos Szeredi * Fix possible race when operation is interrupted 2005-01-28 Miklos Szeredi * Fix compilation on 2.6.7 2005-01-26 Miklos Szeredi * Released 2.2-pre6 2005-01-26 Miklos Szeredi * Fix bug in link() operation which caused the wrong path to be passed as the first argument. Found by Anton Altaparmakov 2005-01-21 Miklos Szeredi * LIB: fix double reply in readdir operation * fusermount: fix uid checking bug. Patch by Adam Connell * KERNEL: fix compile on various RedHat patched 2.4 kernels. Patch by Keshava Gowda 2005-01-20 Miklos Szeredi * KERNEL: provide correct llseek semantics for fuse device (fixes a bug on Progeny 2.4.20 kernel). Reported by Valient Gough 2005-01-20 Miklos Szeredi * Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2) 2005-01-18 Miklos Szeredi * 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 * Released 2.2-pre4 2005-01-17 Miklos Szeredi * 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 * 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 * Remove 'mount_max' and 'user_allow_other' module options. These 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 * 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 * Released 2.2-pre3 2005-01-10 Miklos Szeredi * Add missing code that was accidently left out 2005-01-09 Miklos Szeredi * Released 2.2-pre2 2005-01-09 Miklos Szeredi * 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 * Released 2.2-pre1 2005-01-09 Miklos Szeredi * If FUSE is configured in the kernel, don't build it by default 2005-01-07 Miklos Szeredi * Compile fix by Christian Magnusson 2005-01-05 Miklos Szeredi * Fix compilation for 2.6.{0-5} kernels 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. 2004-12-10 Miklos Szeredi * When mounting on a subdirectory of / don't duplicate slashes at the beggining of path (spotted by David Shaw) 2004-12-09 Miklos Szeredi * Fix bug causing garbage in mount options (spotted by David Shaw) 2004-12-07 Miklos Szeredi * Add 'writepage' flag to 'fuse_file_info'. * More comments in fuse.h * Get rid of double underscores 2004-12-04 Miklos Szeredi * 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 * 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 * Released 2.1 2004-12-01 Miklos Szeredi * 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 * 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 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 * 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 * 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 * Cleaned up kernel in preparation for merge into mainline: * Use /sys/fs/fuse/version instead of /proc/fs/fuse/version * Use real device (/dev/fuse) instead of /proc/fs/fuse/dev * __user annotations for sparse * allocate individual pages instead of kmalloc in fuse_readdir, fuse_read and fuse_write. * Fix NFS export in case "use_ino" mount option is given * 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... * Allow module params to be changed through sysfs 2004-11-14 Miklos Szeredi * Released 2.1-pre1 2004-11-14 Miklos Szeredi * Fix bug in fuse_readpages() causing Oops in certain situations. Bug found by Vincenzo Ciancia. * Fix compilation with kernels versions > 2.6.9. 2004-11-11 Miklos Szeredi * Check kernel interface version in fusermount to prevent strangeness in case of mismatch. * No need to allocate fuse_conn until actual mount happens * Fix potential race between umount and fuse_invalidate * Check superblock of proc file in addition to inode number * Fix race between request_send_noreply() and fuse_dev_release() 2004-11-10 Miklos Szeredi * Separate configure for the kernel directory * Don't allow write to return more than 'count' * Extend kernel interface for future use 2004-11-09 Miklos Szeredi * Fix 'makeconf.sh' to use autoreconf if available 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 FUSE_DIRFIL_COMPAT. * 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 * Added "use_ino" mount option. This enables the filesystems to set the st_ino field on files 2004-11-01 Miklos Szeredi * Fix compile problems with ancient (<=2.4.18) kernels (reported by Jeremy Smith) * Add "allow_root" mount option. Patch by Yaroslav Rastrigin * Clear the 'exited' flag when mail loop is finished 2004-10-28 Miklos Szeredi * Make xattr functions work under 2.6 (bug found by Vincenzo Ciancia) 2004-10-26 Miklos Szeredi * Reset request in fuse_flush() (bugreport by David Shaw) 2004-10-21 Miklos Szeredi * fuse_main() now does not exit on error, rather it returns an error code * Exported __fuse_setup() and __fuse_teardown() functions, which make it easier to implement a custom event loop. * Use daemon() call to background the filesystem after mounting. This function closes the standard input, output and error and changes the current working directory to "/". 2004-10-14 Miklos Szeredi * Released 1.9 2004-10-09 Miklos Szeredi * Don't allow fuse_flush() to be interrupted (bug found by David Shaw) 2004-09-27 Miklos Szeredi * 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) 2004-09-21 Miklos Szeredi * Fix deadlock in case of memory allocation failure. Patch by Christian Magnusson 2004-09-16 Miklos Szeredi * Check memory allocation failures in libfuse 2004-09-14 Miklos Szeredi * Check temporary file creation failure in do_getdir(). Bug spotted by Terje Oseberg 2004-09-13 Miklos Szeredi * Allow "large_read" option for 2.6 kernels but warn of deprecation * Make requests non-interruptible so race with FORGET is avoided. This is only a temporary solution * Support compiling FUSE kernel module on 2.4.x UML kernels 2004-09-09 Miklos Szeredi * Fix bug in case two FORGETs for the same node are executed in the wrong order. Bug spotted and endured for months by Franco Broi, and logfile for solution provided by Terje Oseberg 2004-09-01 Miklos Szeredi * Add -D_REENTRANT to the compile flags * Add documentation of fuse internals by Terje Oseberg 2004-08-16 Miklos Szeredi * Change release method to be non-interruptible. Fixes bug causing missing release() call when program which has opened files is killed (reported by Franco Broi and David Shaw) 2004-07-29 Miklos Szeredi * Add fuse_invalidate() to library API 2004-07-26 Miklos Szeredi * Check permissions in setattr if 'default_permissions' flag is set. Bug spotted by Damjan Lango 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 ./configure * By default don't allow shared writable mappings for non-root. The old behavior can be restored with the 'user_mmap=1' module parameter 2004-07-23 Miklos Szeredi * Clean up mount option passing to fusermount and to fuse_new() BEWARE: this changes the userspace API slightly, and the command line usage of programs using fuse_main() 2004-07-20 Miklos Szeredi * Optimize reading under 2.6 kernels by issuing multiple page asynchronous read requests 2004-07-18 Miklos Szeredi * Only use redirty_page_for_writepage() for kernels >= 2.6.6 2004-07-16 Miklos Szeredi * Separate directory entry and inode attribute validity timer * New write semaphore to stop page writeback during truncate * Fsync now waits for all writes to complete before sending the request * Optimization: if a page is completely written by fuse_commit_write(), clear the dirty flag and set the uptodate 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. * Use redirty_page_for_writepage() in fuse_writepage() for skipped pages (2.6 only) * Set set_page_dirty address space operation (2.6 only) 2004-07-06 Miklos Szeredi * Minor fix in read: print debug info even if read size is zero 2004-07-04 Miklos Szeredi * Fix race between truncate and writepage (fsx-linux now runs without error) 2004-07-02 Miklos Szeredi * Fix kernel hang on mkfifo under 2.4 kernels (spotted and patch by Mattias Wadman) * Added option for direct read/write (-r) * Fix revalidate time setting for newly created inodes * Remove uid==0 check for '-x' option in fusermount (kernel checks this) * fuse_main() only installs handlers for signals (out of INT, HUP, TERM, PIPE), for which no handler has yet been installed * Add module option 'user_allow_other' which if set to non-zero will allow non root user to specify the 'allow_other' mount option ('-x' option of fusermount) * Fix deadlock between page writeback completion and truncate (bug found by Valient Gough with the fsx-linux utility) 2004-07-01 Miklos Szeredi * Change passing fuse include dir to 2.6 kernel make system more robust (fixes compile problems seen on SuSE 9.1 with updated 2.6 kernel) 2004-06-30 Miklos Szeredi * Acquire inode->i_sem before open and release methods to prevent concurrent rename or unlink operations. * Make __fuse_read_cmd() read only one command. This allows multiplexing the fuse file descriptor with other event sources using select() or poll() (patch by Jeff Harris) * Export 'exited' flag with __fuse_exited() (patch by Jeff Harris) 2004-06-27 Miklos Szeredi * Fix file offset wrap around at 4G when doing large reads 2004-06-24 Miklos Szeredi * Fix memory leak in open (Valient Gough) 2004-06-24 Miklos Szeredi * Add "close after delete" support to libfuse (patch by Valient Gough) * Cancel all worker threads before exit in multithreaded mode 2004-06-23 Miklos Szeredi * Fix locking bugs * Don't send reply to RELEASE * Work with newer libtool (1.5a) * Check for st_atim member of struct stat 2004-06-22 Miklos Szeredi * No request allocation needed on inode and file release 2004-06-21 Miklos Szeredi * Fix possible inode leak in userspace in case of unfinished lookup/mknod/mkdir/symlink/link operation. 2004-06-20 Miklos Szeredi * Fix some races and cleanups in fuse_read_super() 2004-06-19 Miklos Szeredi * Requests are allocated at open time 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 (e.g. find) 2004-05-18 Miklos Szeredi * Added flush() call 2004-05-04 Miklos Szeredi * Extended attributes support for 2.4 (patch by Cody Pisto) 2004-04-20 Miklos Szeredi * Fixed parser with modversions (Mattias Wadman) 2004-04-19 Miklos Szeredi * Added mount option parser to 2.4 build 2004-04-13 Miklos Szeredi * Replaced binary mount data with text options * Show FUSE specific mount options in /proc/mounts * Check in fuse.h whether _FILE_OFFSET_BITS is set to 64 2004-04-09 Miklos Szeredi * Check some limits so userspace won't get too big requests 2004-04-05 Miklos Szeredi * Kill compile warning * Upgraded user-mount patch for 2.6.5 2004-04-02 Miklos Szeredi * Add detection of user-mode-linux to configure 2004-03-31 Miklos Szeredi * fixed zero size case for getxattr and listxattr 2004-03-30 Miklos Szeredi * new fusermount flag '-z': lazy unmount, default is not lazy * Extended attributes operations added (getxattr, setxattr, listxattr, removexattr) 2004-03-25 Miklos Szeredi * If filesystem doesn't define a statfs operation, then an all-zero default statfs is returned instead of ENOSYS 2004-03-24 Miklos Szeredi * Add FS_BINARY_MOUNTDATA filesystem flag for kernels > 2.6.4 2004-03-09 Miklos Szeredi * Fix for uClinux (Christian Magnusson) 2004-03-02 Miklos Szeredi * fuse_main() adds "-n progname" to the fusermount command line * More kernel interface changes: * Lookup/getattr return cache timeout values 2004-02-25 Miklos Szeredi * Clean up option parsing in fuse_main() * Added fuse_get() function which returns the fuse object created by fuse_main() 2004-02-20 Miklos Szeredi * removed old way of mounting (fusermount mountpoint program) * more kernel interface changes: * added nanosecond precision to file times * removed interface version from mount data * added /proc/fs/fuse/version which contains MAJOR.MINOR 2004-02-19 Miklos Szeredi * statfs library API changed to match other methods. Since this is not backward compatible FUSE_MAJOR_VERSION is changed to 2 * kernel interface changes follow: * statfs changed to 64 bits, added 'bavail' field * add generation number to lookup result * optimized mknod/mkdir/symlink/link (no separate lookup is needed) * rdev size increased to 32 bits for mknod * kernel interface version changed to 3.1 2004-02-18 Miklos Szeredi * user-mount upgraded for 2.6.3 kernel 2004-02-17 Miklos Szeredi * Added user-mount.2.6.2-rc3.patch * Add FS_SAFE flag to fuse filesystem * fusermount should allow (un)mounting for non-root even if not suid-root 2004-02-12 Miklos Szeredi * Remove MS_PERMISSION mount flag (that means something else now) 2004-02-10 Miklos Szeredi * Added check for i_size_read/write functions to configure.in (patch by Valient Gough) 2004-02-06 Miklos Szeredi * Fixed writing >= 2G files * Check file size on open (with generic_file_open()) * Readpage calls flush_dcache_page() after storing data * Use i_size_read/write for accessing inode->i_size * Make loopback mount of a fuse file work 2004-02-04 Miklos Szeredi * Released 1.1 2004-01-29 Miklos Szeredi * Properly check if the inode exists in fuse_invalidate 2004-01-27 Miklos Szeredi * Added -q option for fusermount * fuse_unmount() now uses -q option of fusermount, so no error is printed if the cause of the program exit is that the filesystem has already been unmounted * Fix i_nlink correctness after rmdir/unlink 2004-01-26 Miklos Szeredi * Released 1.1-pre2 2004-01-26 Miklos Szeredi * Fix typo (thanks Marcos Dione) * Compile fixes for 2.4 kernels 2004-01-23 Miklos Szeredi * Fix CONFIG_MODVERSIONS compile on 2.6 2004-01-22 Miklos Szeredi * Write all pending data before a RELEASE operation * Suppress 'Bad file descriptor' warning on exit * Replaced fusermount option '-d xxx' with '-n xxx' so it doesn't get confused with '-d' of fuse_main() (sorry about this change) * New fusermount option '-l' which enables big reads. Big reads are now disabled by default. * fuse_main() can accept fusermount arguments after a '--' 2004-01-19 Miklos Szeredi * Support for exporting filesystem over NFS (see README.NFS) 2004-01-14 Miklos Szeredi * Support non-blocking writepage on 2.6. This makes FUSE behave much more nicely in low-memory situations * Fix 32-bit dev handling in getattr and mknod for 2.6 kernels. (Note: the mknod method does not yet use 32bit device number) 2004-01-13 Miklos Szeredi * Code cleanups 2004-01-07 Miklos Szeredi * Released 1.1-pre1 2004-01-06 Miklos Szeredi * Integrated 2.6 kernel support patch by Michael Grigoriev * Improvements and cleanups for 2.6 kernels 2004-01-05 Miklos Szeredi * Added -d option to fusermount 2003-12-15 Miklos Szeredi * Added major+minor version to library API, and minor version to kernel API 2003-12-13 David McNab * Implemented fsync support in examples/example.py * Implemented 'fsync' and 'statfs' methods in python interface 2003-12-12 Miklos Szeredi * Make it compile on 2.4.19. * Add fsync operation (write file failed on xemacs & vi) 2003-12-12 David McNab * Added distutils support to the python module, as per standard python development practice 2003-12-11 Miklos Szeredi * Add file locking for mount/unmount (based on patch by Valient Gough) 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 2003-11-04 Miklos Szeredi * Fix kernel version detection (again). Bugreport by Peter Levart 2003-11-03 Miklos Szeredi * Applied read combining patch by Michael Grigoriev (tested by Valient Gough and Vincent Wagelaar) 2003-10-22 Miklos Szeredi * Mtab handling fix in fusermount by "Valient Gough" (SF patch #766443) 2003-10-13 Miklos Szeredi * Error code fixes in kernel module 2003-10-04 Miklos Szeredi * kernel version detection fix * fusermount now uses "lazy" umount option * fusermount can use modprobe with module-init-tools 2003-09-08 Miklos Szeredi * Integrated caching patch by Michael Grigoriev * Added "Filesystems" file with descriptions of projects using FUSE * Added patch by Michael Grigoriev to allow compliation of FUSE kernel module for 2.6 kernels 2003-06-02 Miklos Szeredi * And another spec-file fix by Achim Settelmeier 2003-05-26 Miklos Szeredi * Spec-file fix by Achim Settelmeier 2003-03-10 Miklos Szeredi * Fix umount oops (found by Samuli Kärkkäinen) 2003-03-05 Miklos Szeredi * Merge of fuse_redhat.spec and fuse.spec by Achim Settelmeier 2003-03-04 Miklos Szeredi * Updated fuse.spec file (Achim Settelmeier) 2003-02-19 Miklos Szeredi * Version 1.0 released 2003-02-12 Miklos Szeredi * SuSE compilation fix by Juan-Mariano de Goyeneche 2002-12-10 Miklos Szeredi * The release() VFS call is now exported to the FUSE interface 2002-12-05 Miklos Szeredi * 64 bit file offset fixes in the fuse kernel module * Added function 'fuse_exit()' which can be used to exit the main loop 2002-12-03 Miklos Szeredi * Added _FILE_OFFSET_BITS=64 define to fuse.h. Note, that this is an incompatible interface change. 2002-10-28 Miklos Szeredi * Portablility fix (bug reported by C. Chris Erway) 2002-10-25 Miklos Szeredi * Use Mark Glines' fd passing method for default operation instead of old reexec 2002-10-22 Miklos Szeredi * fix "Stale NFS file handle" bug caused by changes in 2.4.19 2002-10-22 Miklos Szeredi * fix incompatiblity with Red Hat kernels, with help from Nathan Thompson-Amato. 2002-04-18 Mark Glines * added an alternative to fuse_mount(), called fuse_mount_ioslave(), which does not need to reexec the FUSE program. * added a small helper util needed by fuse_mount_ioslave(). 2002-03-16 Mark Glines * use struct fuse_statfs everywhere possible to avoid problems with the headerfiles changing struct statfs member sizes 2002-03-01 Miklos Szeredi * Another RPM spec file for RedHat >= 7 by Ian Pilcher 2002-01-14 Miklos Szeredi * RPM support by Achim Settelmeier 2002-01-09 Miklos Szeredi * Version 0.95 released 2002-01-09 Miklos Szeredi * Revaidate all path components not just the last, this means a very small performance penalty for being more up-to-date. 2002-01-08 Miklos Szeredi * Update and fix python interface 2002-01-07 Mark Glines * Added statfs() support to kernel, lib, examples, and perl! 2001-12-26 Miklos Szeredi * Better cross compilation support * Ported to Compaq IPAQ 2001-12-20 Miklos Szeredi * Added function fuse_get_context() to library API (inspired by patch from Matt Ryan) * Added flags to fusermount and to kernel interface to control permission checking * Integrated fuse_set_operations() into fuse_new() 2001-12-08 Miklos Szeredi * Applied header protection + extern "C" patch by Roland Bauerschmidt 2001-12-02 Miklos Szeredi * Added perl bindings by Mark Glines 2001-11-21 Miklos Szeredi * Cleaned up way of mounting simple filesystems. * fuse_main() helper function added 2001-11-18 Miklos Szeredi * Optimized read/write operations, so that minimal copying of data is done 2001-11-14 Miklos Szeredi * Python bindings by Jeff Epler added 2001-11-13 Miklos Szeredi * Fixed vfsmount reference leak in fuse_follow_link * FS blocksize is set to PAGE_CACHE_SIZE, blksize attribute from userspace is ignored 2001-11-09 Miklos Szeredi * Started ChangeLog
