* Updated kernel API headers.Gravatar Nikolaus Rath2016-11-22
| | | | Taken from Linux kernel commit 27bcd37.
* libfuse: add "clone_fd" optionGravatar Miklos Szeredi2015-05-18
| | | | | This creates a separate device file descriptor for each processing thread, which might improve performance.
* libfuse: add FUSE_CAP_NO_OPEN_SUPPORT flag to ->init()Gravatar Miklos Szeredi2015-04-23
|
* libfuse: add flags to ->rename()Gravatar Miklos Szeredi2014-07-15
| | | | See renameat2() system call in linux-3.15 and later kernels.
* libfuse: allow setting ctime in ->setattr()Gravatar Miklos Szeredi2014-07-15
|
* libfuse: add "time_gran" optionGravatar Miklos Szeredi2014-07-15
| | | | | | This allows the filesystem to specify the time granularity it supports when the kernel is responsible for updating times ("writeback_cache" option).
* libfuse: Add "async_dio" and "writeback_cache" optionsGravatar Miklos Szeredi2014-01-29
| | | | | Asynchronous direct I/O is supported by linux kernels 3.13 and later, writeback caching is supported by 3.14 and later.
* fuse: synchronize fuse_kernel.h header with the linux kernelGravatar Miklos Szeredi2013-05-20
| | | | | Check for __KERNEL__ instead of __linux__ and use the standard int types instead of the linux specific ones.
* libfuse: allow disabling adaptive readdirplusGravatar Eric Wong2013-02-07
| | | | | | | | | | | This switches the -o no_readdirplus option to a tristate string: -o readdirplus=(yes|no|auto) Telling the kernel to always use readdirplus is beneficial to filesystems (e.g. GlusterFS) where the cost to perform readdir and readdirplus are identical. The default remains "auto" (if supported).
* libfuse: add poll_events to fuse_file_infoGravatar Enke Chen2013-02-07
| | | | | Make requested poll events available to the filesystem. If the requested eventsare not available, then this field is zero.
* libfuse: add readdirplus support in fuse_lowlevel_opsGravatar Feng Shuo2013-02-07
| | | | | | | | | | | | | | | | | This patch implements readdirplus support in FUSE usersapce. It adds a new fuse lowlevel operations fuse_lowleve_ops::readdir_plus, corespoding mount options and helper functions to maintain buffer. [From: Eric Wong <normalperson@yhbt.net>] This makes our terminology consistent with NFS and our kernel module, as well as reducing user/developer confusion in the command-line. Note: I'm keeping "fuse_add_direntry_plus" since that is less standardized in its use than "readdirplus" for now. Signed-off-by: Feng Shuo <steve.shuo.feng@gmail.com>
* fuse_kernel.h: clean includesGravatar Riku Voipio2013-02-07
| | | | | Use <linux/types.h> for linux and define types used for other operating systems using <stdint.h> types.
* libfuse: Add '[no_]auto_inval_data' mount optionGravatar Feng Shuo2013-02-06
| | | | | | | | | | | Several caching logic changes have been made on the kernel side to better support network-based fuse filesystems. These include kernel side mtime checking and read path cache revalidation. The new caching logic is enabled through the FUSE_AUTO_INVAL_DATA init flag. Export this to the user via the '[no_]auto_inval_data' mount option. Signed-off-by: Feng Shuo <steve.shuo.feng@gmail.com>
* libfuse: add missing INIT flagsGravatar Miklos Szeredi2013-02-06
| | | | | Add missing flags that userspace derived from the protocol version number. This makes the protocol more flexible.
* Add FALLOCATE operationGravatar Anatol Pomozov2012-06-18
| | | | | | fallocate filesystem operation preallocates media space for the given file. If fallocate returns success then any subsequent write to the given range never fails with 'not enough space' error.
* use flexible array in include/fuse_kernel.hGravatar Miklos Szeredi2012-04-20
| | | | | Use the ISO C standard compliant form instead of the gcc extension in the interface definition.
* Revert "Add mmap() and munmap() methods to low level API"Gravatar Miklos Szeredi2012-01-24
| | | | | | | | | | This partially reverts commit 4b2157c44e6ad7e692fcffb7450143e83151d36b. Remove mmap/munmap suppor as this missed the interface changes for Linux-3.3 (API version 7.18). Only revert the mmap/munmap bits and leave the retrieve_reply API fix in place as well as the optimization in fuse_send_data_iov_fallback().
* libfuse: Notifying the kernel of deletion.Gravatar John Muir2011-12-07
| | | | | | | | | libfuse part to allow a FUSE file-system to tell the kernel when a file or directory is deleted. If the specified dentry has the specified inode number, the kernel will unhash it. Signed-off-by: John Muir <john@jmuir.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
* Add mmap() and munmap() methods to low level APIGravatar Miklos Szeredi2011-12-06
| | | | | Currently this is only useful for CUSE. Also update retrieve_reply() method.
* Add support for ioctl on directoriesGravatar Miklos Szeredi2011-12-05
| | | | Reported by Antonio SJ Musumeci
* Add ->flock() operation to low and high level interfacesGravatar Miklos Szeredi2011-07-06
| | | | | | | | | | This fixes problems with emulating flock() with POSIX locking. Reported by Sebastian Pipping. As with lock/setlk/getlk most filesystems don't need to implement this, as the kernel takes care of file locking. The only reason to implement locking operations is for network filesystems which want file locking to work between clients.
* Fix ioctl ABIGravatar Miklos Szeredi2011-05-19
| | | | | Fix the ambiguity of ioctl ABI on the kernel/userspace boundary for 32bit vs. 64bit userspace
* Allow batching of forget requestsGravatar Miklos Szeredi2011-05-19
| | | | | This allows forget requests to be processed faster and doesn't require a modification to fuse filesystems. Reported by Terje Malmedal
* libfuse: add retrieve requestGravatar Miklos Szeredi2010-11-08
| | | | Retrieve data stored in the kernel buffers for a given inode.
* libfuse: add store requestGravatar Miklos Szeredi2010-11-08
| | | | Request data to be stored in the kernel buffers for a given inode.
* update fuse_kernel.hGravatar Miklos Szeredi2010-06-23
|
* * Make the number of max background requests and congestionGravatar Miklos Szeredi2010-06-23
| | | | threshold tunable.
* * Clarify how the protocol version should be negotiated betweenGravatar Miklos Szeredi2009-07-16
| | | | | kernel and userspace. Notably libfuse didn't correctly handle the case when the supported major versions didn't match
* * The context is extended with a 'umask' field. The umask is sentGravatar Miklos Szeredi2009-07-02
| | | | | | | | | | | | | | | for mknod, mkdir and create requests by linux kernel version 2.6.31 or later, otherwise the umask is set to zero. Also introduce a new feature flag: FUSE_CAP_DONT_MASK. If the kernel supports this feature, then this flag will be set in conn->capable in the ->init() method. If the filesystem sets this flag in in conn->want, then the create modes will not be masked. * Add low level interfaces for lookup cache and attribute invalidation. This feature is available in linux kernels 2.6.31 or later. Patch by John Muir * Kernel interface version is now 7.12
* CUSE patches from Tejun HeoGravatar Miklos Szeredi2009-06-18

* * Implement ioctl support. On high level interface onlyGravatar Miklos Szeredi2008-12-05
| | | | | | | "restricted" ioctls are supported (which are defined with the _IO(), _IOR(), _IOW() or _IOWR() macros). Unrestricted ioctls will only be allwed to CUSE (Character Device in Userspace) servers. Patch by Tejun Heo
* If open sets fi->nonseekable, libfuse will tell the kernel that the file is ↵Gravatar Miklos Szeredi2008-11-28
