2020-01-31Update comment for the copy_file_range operation (#497)Florian Weimer
copy_file_range was first implemented with copy-based emulation in glibc 2.27, but the emulation was subsequently removed again because correct emulation depends on why the application attempted to make a copy. Therefore, file systems cannot rely on low-level userspace performing emulation.
2020-01-27Remove trailing comma in enums (#494)zsugabubus
They are illegal in C89/90.
2019-12-31Style: Fix an indention in comments (#480)Changli Gao
2019-12-31Bump FUSE_MINOR_VERSIONNikolaus Rath
This was forgotten over several releases.
2019-12-31Make ioctl prototype conditional on FUSE_USE_VERSION. (#482)Bill Zissimopoulos
Define FUSE_USE_VERSION < 35 to get old ioctl prototype with int commands; define FUSE_USE_VERSION >= 35 to get new ioctl prototype with unsigned int commands. Fixes #463.

2019-09-10log: move fuse_log() to the public header fileStefan Hajnoczi
Applications may wish to call fuse_log() for unified logging. This way they don't need to define their own wrappers to invoke the log message handler function installed by fuse_set_log_func(). Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2019-09-04Introduce callback for loggingStefan Hajnoczi
Introduce an API for custom log handler functions. This allows libfuse applications to send messages to syslog(3) or other logging systems. See include/fuse_log.h for details. Convert libfuse from fprintf(stderr, ...) to log_fuse(level, ...). Most messages are error messages with FUSE_LOG_ERR log level. There are also some debug messages which now use the FUSE_LOG_DEBUG log level. Note that lib/mount_util.c is used by both libfuse and fusermount3. Since fusermount3 does not link against libfuse, we cannot call fuse_log() from lib/mount_util.c. This file will continue to use fprintf(stderr, ...) until someone figures out how to split it up.

2019-07-09Sync fuse_kernel.h with Linux 5.2 (#433)Kirill Smelkov
2019-05-24Remove incorrect comment about fuse_entry_param.generation (#420)Alan Somers
A comment said that fuse_entry_param.generation must be non-zero. However, I can't find anything in the kernel that requires that, and real-world file systems don't seem to follow that advice, either.
2019-04-16Add documentation for opting out of opendir and releasedir (#391)Chad Austin
2019-04-06Add support for in-kernel readdir caching.Nikolaus Rath
Fixes: #394.
2019-04-06Synchronize fuse_kernel.h with current kernel master.Nikolaus Rath
2019-04-06Delete FUSE_FSYNC_FDATASYNCNikolaus Rath
This constant is not defined in the kernel, so it will be lost when fuse_kernel.h is not synchronized. Instead, the kernel just passes a flag value of "1", so for now we also use a literal in userspace.
2019-04-06Various documentation improvementsAlan Somers
See issue #389 for some related discussions.
2019-03-11Defined the (*ioctl)() commands as unsigned int (#381)Jean-Pierre André
Instead of the Posix ioctl(2) command, Linux uses its own variant of ioctl() in which the commands are requested as "unsigned long" and truncated to 32 bits by the fuse kernel module. Transmitting the commands to user space file systems as "unsigned int" is a workaround for processing ioctl() commands which do not fit into a signed int.

2018-11-19libfuse: add copy_file_range() supportNiels de Vos
Add support for the relatively new copy_file_range() syscall. Backend filesystems can now implement an efficient way of cloning/duplicating data ranges within files. See 'man 2 copy_file_range' for more details.
2018-11-19Update kernel API headersNiels de Vos
Taken from Linux kernel commit 3b7008b226f3.
2018-11-06Document when `fuse_lowlevel_notify_*` functions may block.Nikolaus Rath
2018-10-09Add unprivileged option in `mount.fuse3`Mattias Nissler
The unprivileged option allows to run the FUSE file system process without privileges by dropping capabilities and preventing them from being re-acquired via setuid / fscaps etc. To accomplish this, mount.fuse sets up the `/dev/fuse` file descriptor and mount itself and passes the file descriptor via the `/dev/fd/%u` mountpoint syntax to the FUSE file system.

2017-08-24Add idle_threads mount option.Joseph Dodge
2017-08-24Allow inode cache invalidation in high-level APISławek Rudnicki
We re-introduce the functionality of invalidating the caches for an inode specified by path by adding a new routine fuse_invalidate_path. This is useful for network-based file systems which use the high-level API, enabling them to notify the kernel about external changes. This is a revival of Miklos Szeredi's original code for the fuse_invalidate routine.

This should simplify the code a lot. It also corrects a bug in that the (former) add_default_fsname() function actually set the -osubtype option.

2017-07-13Only declare fuse_new_30() when FUSE_USE_VERSION == 30Nikolaus Rath
This function shouldn't be called when using a newer fuse version, so we should not define it in that case.

2017-07-08Fixed description of struct fuse_conn_info->time_granNikolaus Rath
At least on Linux kernel 4.9, a value of zero gives more than 1-sec accuracy.
