Add struct fuse_args Introduce bpf_arg in fuse_reply_entry Currently, the opcode filters are zeroed to preserve the libfuse compatibility. Bug: 202785178 Test: Along with other changes, file /sys/fs/bpf/prog_fuse_media_fuse_media appears.

2021-05-19Define FUSE_USE_VERSION in Doxygen. (#608)Junichi Uekawa
We currently do not pass anything in PREDEFINED and that means FUSE_USE_VERSION is undefined. Add that definition so that Doxygen built-in C pre-processor can use FUSE_USE_VERSION value to find the correct comment to parse.
2021-05-07Fix doxygen warnings. (#600)Junichi Uekawa
Some parameters were undocumented, and @file does not mean to expand current file name.

2020-11-12Enable passthrough mode for read/write operationsAlessio Balsini
Add support for filesystem passthrough read/write of files. When the FUSE_PASSTHROUGH capability is enabled, the FUSE daemon may decide while handling the "open" or "create" operation, if the given file can be accessed by that process in "passthrough" mode, meaning that all the further read and write operations would be forwarded by the kernel directly to the lower filesystem rather than to the FUSE daemon. All requests that aren't read or write are still handled by the userspace code. This allows for an improved performance on reads and writes, especially in the case of reads at random offsets, for which no (readahead) caching mechanism would help, reducing the performance gap between FUSE and native filesystem access. Extend also the passthrough_hp example with the new passthrough feature.

2020-08-09Define fuse_session_loop_mt as a macro on uclibc and MacOS (#532)asafkahlon
On uclibc and MacOS we don't use versioned symbols. Hence, there's no definition for fuse_session_loop_mt on those cases and the linker won't be able to resolve calls to fuse_session_loop_mt() Signed-off-by: Asaf Kahlon <asafka7@gmail.com>
2020-01-10Support FUSE_CANONICAL_PATH in libfuseZim
FUSE_CANONICAL_PATH opcode, (2016) was added in some Android kernels to support inotify. Add canonical path handlers in libfuse and create a patch file to easily apply this patch on top of updates. Test: inotify - /sdcard on Taimen Test: atest FileObserver Bug: 147482155 Change-Id: I97a2c4247aa3e4a70af697569b56662a0755f72b
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.
2019-11-09Update to libfuse 3.8.0Zim
The latest release allows a custom logger Bug: 135341433 Test: adb shell ls /sdcard with persist.sys.fuse Change-Id: Iaa8a2bb7b6da3f364fba41b443527a998a26549f

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
2019-03-11Defined 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.
