2025-07-21example/memfs_ll: Avoid nullptr field initializations by pragmaBernd Schubert-29/+3
These nullptr initializations don't make sense - methods that are not explicitly set are not implemented. I thought that C++20 would eventually avoid the nullptr, but looks like compilers still give warnings - avoid them with a pragma. Signed-off-by: Bernd Schubert <bschubert@ddn.com>
2025-07-16memfs_ll: fix deadlock in truncate operationLong Li-1/+0
Remove redundant mutex lock acquisition in the truncate() method to prevent deadlock. The issue occurs when memfs_setattr() already holds the mutex lock and then calls truncate(), which attempts to acquire the same lock again. Signed-off-by: Long Li <leo.lilong@huawei.com>
2025-07-16Avoid double unmount on FUSE_DESTROYBernd Schubert-12/+24
This is a long standing issue, a system could have unmounted /path/to/mnt and then fuse-client/kernel would send FUSE_DESTROY, which would then again try a umount. Given that FUSE_DESTROY is async, that umount might arrive any time later and might possibly unmount a wrong mount point. A warning as in issue #1286 is just minor to that. Code wise this uses atomics to free the char *, as FUSE_DESTROY might race with a signal and a double free might be possible without proctection. A lock might run into the same issue, if the signal would arrive at the wrong time a double lock would be possible. Additionally, fuse_session_mount() is updated, to first duplicatate the pointer and to then do the kernel mount - reverting the kernel mount in case of strdup() failure is much harder.

2025-07-16fusermount: Fix the close_range ifdefBernd Schubert-2/+2
This fixes commit 82bcd818 That commit had removed HAVE_LINUX_CLOSE_RANGE in meson generation, but didn't remove the usage in fusermount.c - fusermount was then not using the close_range syscall. Closes: https://github.com/libfuse/libfuse/issues/1284 Signed-off-by: Bernd Schubert <bernd@bsbernd.com>
2025-07-16Add statx supportJoanne Koong-2/+391
This commit adds libfuse support for FUSE_STATX requests on linux distributions. Currently, statx is only supported on linux. To make the interface a ergonomic as possible (eg using native 'struct statx' vs 'struct fuse_statx'), this implementation gates the 'struct statx' changes by #ifdef linux.

2025-07-13example/passthrough: support fspacectl()CismonX-1/+14
FreeBSD 14 introduced a new system call, fspacectl(). Currently, it supports one operation mode, SPACECTL_DEALLOC, which is functionally equivalent to Linux fallocate() with FALLOC_FL_KEEP_SIZE|FALLOC_FL_PUNCH_HOLE flags. fspacectl() calls with SPACECTL_DEALLOC is supported on FUSE filesystems via FUSE_FALLOCATE with the aforementioned flags.

2025-06-17mount_util.c: check if utab exists before updateGeorgi Valkov-0/+4
Do not attempt to update /run/mount/utab if it doesn't exist. Note: if this path ever changes, utab updates will break. Fixes the following error when mounting iPhone using ifuse: ifuse /mnt --container com.httpstorm.httpstorm mount: mounting ifuse on /mnt failed: Invalid argument On OpenWRT by default mount-utils is not installed and utab does not exist. /bin/mount is a symlink to /bin/busybox and does not support updating of utab. If mount-utils is installed: /run/mount/ exists, but does not contain utab. The mount-utils instance is under /usr/bin/mount, so a hard-coded call to /bin/mount will still fail. Using /usr/bin/mount succeeds but does not create utab. [1] https://github.com/libfuse/libfuse/pull/1247 Signed-off-by: Georgi Valkov <gvalkov@gmail.com>

2025-06-12help: Remove duplicate io_uring options from fuse_cmdline_helpizxl007-5/+1
The io_uring options are currently shown in both fuse_cmdline_help() and fuse_lowlevel_help(), which creates unnecessary duplication. Since io_uring is a low-level I/O feature, it makes more sense to only show these options in fuse_lowlevel_help(). This change: - Removes io_uring options from fuse_cmdline_help() - Keeps them in fuse_lowlevel_help() where they belong - Removes the FIXME comment that is no longer needed This is purely a documentation improvement and does not affect any functionality. Users will still see all available options when using --help, just organized in a more logical way. Signed-off-by: izxl007 <zeng.zheng@zte.com.cn>

2025-06-05Update how to use the io_uring and io_uring_q_depth mount optionsizxl007-25/+6
This patch updates how to use the io_uring and io_uring_q_depth mount options. There are two reasons for this: 1. It is recommended for end-users to use a format like “-o io_uring" (with a space) in README.fuse-io-uring. This is because, in the passthrough_hp example, cxxopts does not support the "-oio_uring" format (without a space), and using it would result in a syntax error. 2. Remove redundant "--uring" and "--uring-q-depth=" from passthrough_hp example. Signed-off-by: izxl007 <zeng.zheng@zte.com.cn>

2025-05-20conn->want conversion: Fix fuse_apply_conn_info_opts()Bernd Schubert-106/+187
fuse_apply_conn_info_opts() was applying to 'want_ext', which would cause conflicts with 'want' if the application applied its own flags to 'conn->want'. Solution is: - to move fuse_{set,unset,get}_feature_flag and convert_to_conn_want_ext() to fuse_lowlevel.c and to define them as part of the public API, although convert_to_conn_want_ext() should not be used - it is currently needed to be a public function due as it needs to be defined for the tests. Related to https://github.com/libfuse/libfuse/issues/1171 and https://github.com/libfuse/libfuse/pull/1172.
