2025-03-18fusermount: prevent stdio FDs from being reusedBernd Schubert-28/+54
Redirect stdin/stdout/stderr to /dev/null to prevent newly opened file descriptors from reusing these low numbers (0,1,2) and potential issues with that. Signed-off-by: Bernd Schubert <bschubert@ddn.com>
2025-03-14fuse_common.h: Convert back FUSE_CAP_ from enum to definesBernd Schubert-322/+315
Some applications use that for detection of features between distributions/libfuse version. Closes: https://github.com/libfuse/libfuse/issues/1163 Signed-off-by: Bernd Schubert <bschubert@ddn.com> (cherry picked from commit 3ae5ca7443348aabad9bc71b9d5b0999f8292379)
2025-03-14Add PanFS to whitelistjnr0006-0/+1
Added PanFSto whitelist. This should allow us to mount gocryptfs onto the parallel filesystem. Signed-off-by: Jacob Riley <jnr0006@uah.edu> (cherry picked from commit 3a291c355f3a4966ff3ebb6841b31da0d3010f52)
2025-02-20mount: fix closing stdout/err and error logsVassili Tchersky-10/+11
Don't spawn a setuid children with FD 1&2 closed. Check status and not errno after posix_spawn(p). Add comments to fix later error checking, as posix_spawn(p) returns non-zero status only if clone/vfork/rfork fails. If only setup (open, dup2) or execve fails, the forked process exit with 127 but posix_spawn returns zero. Signed-off-by: Vassili Tchersky <vt+git@vbc.su>
2025-02-18Released fuse-3.17.1-rc1Bernd Schubert-4/+16
2025-02-18github ci tests: Update the stable branch name to include fuse-Bernd Schubert-9/+15
The branch is actually called fuse-3.17.x Also disable checkpatch for branches except master, as it is to do basic checks, while stable branches do not need that check, assuming cherry-pick happens from master. Issue with it is that persistently complains about dependabot changes. Signed-off-by: Bernd Schubert <bernd@bsbernd.com>

2025-02-18Avoid nested function declarations in helper functionsBernd Schubert-62/+28
libfuse-3.17 introduced several functions that should only be called via inlined helper functions, never directly. To enforce this, these functions were declared within the inlined functions. However, this triggers the compiler warning "-Werror=nested-externs". While this warning is valid, the nested declarations were intentional to prevent direct usage of these functions. Rather than suppressing the warning with pragmas, move these function declarations outside the helper functions while maintaining the intended access restrictions through other means. Closes: https://github.com/libfuse/libfuse/issues/1134 Signed-off-by: Bernd Schubert <bschubert@ddn.com>
2025-02-18mount_bsd: Remove unused headersVassili Tchersky-4/+0

2025-02-18mount_bsd: Fix usage of libfuse_strtolVassili Tchersky-3/+4
The check on fd < 0 was recently removed. However, this check is important as the content of FUSE_DEV_FD is passed as-is to mount_fusefs, and a string beginning by '-' is treated as an option. Additionally, add a proper include and type. Signed-off-by: Vassili Tchersky <vt+git@vbcy.org>

The UFSD super magic is larger than 32-bit - I don't know if truncating to 32-bit would work - we just exclude it for now. Signed-off-by: Bernd Schubert <bschubert@ddn.com>
2025-02-18Fix build of example/memfs_ll.cc on 32 bit architecturesLaszlo Boszormenyi (GCS)-2/+2
The code uses std::min() which expects its arguments to be size_t. Two times it uses an offset declared as off_t. While both size_t and off_t are 32-bit integers, the latter is signed. On 64 bit architectures the conversation of off_t -> size_t performed automatically. On 32 bit architectures it needs a type cast. Signed-off-by: Laszlo Boszormenyi (GCS) <gcs@debian.org>

Another additon for https://github.com/libfuse/libfuse/issues/1092 Use _fuse_new_versioned() instead of _fuse_new_317 and actually also remove symbol versioning for it - we don't need it. Signed-off-by: Bernd Schubert <bernd@bsbernd.com>

2025-02-10Rename to fuse_session_new_versionedBernd Schubert-50/+35
Similar previous renames to fuse_main_real_versioned, but here for the low level fuse_session_new. Also remove symbol versioned as part of "fuse_session_new" as that function is not part of the official API/ABI and to allow easier access with dlopen/dlsym. Also switch back to a macro fuse_session_new, just in case some code has some expectations on that. Signed-off-by: Bernd Schubert <bernd@bsbernd.com>

2025-02-10fuse_lowlevel.c: drop incorrect comment from convert_to_conn_want_ext()Luis Henriques-2/+0
The comment is probably a leftover from older versions, as the application of the 32 bits of conn.capable_ext to conn.capable is done before function convert_to_conn_want_ext() is invoked. Signed-off-by: Luis Henriques <luis@igalia.com>
2025-02-10fuse_lowlevel.c: fix possible 64 bits value truncationLuis Henriques-1/+1
Because conn.want_ext is a uint64_t, copying it into a uint32_t may result in truncating it's value. This patch fixes a bug in do_init() where the 32 bits copy is again converted into a 64 bits value, because it will be used in convert_to_conn_want_ext().

2025-02-10Identify the FD hold by parent processZegang-0/+17
Issue: There is no directly way to get the FD hold by parent process which asked do fuse mount. Use Case: For auto_unmount case, identify the FD can easy to close the FD and make automatically unmount manually and explicitly. The FD[1] can be got via getenv(FUSE_COMMFD2_ENV). One potential use case is to satisfy FD-Leak checks. Solution: Add an extra env _FUSE_COMMFD2 to store the FD. This will provide a easy way to get the FD via FUSE_COMMFD2_ENV.

2025-02-10Make fuse_main_real() not symboledBernd Schubert-29/+45
Addresses https://github.com/libfuse/libfuse/issues/1092 We actually don't need to make fuse_main_real() symboled, as it is not part of the official API. The inlined function now always calls into fuse_main_real_317 and the compat ABI function (which should also be available for dlopen/dlsym) is now always compiled, independent if the compiler/linker support versioned symbols. Additionally, fuse_main_real() is also declared as inlined function and a warning message is created when that function is called. Signed-off-by: Bernd Schubert <bernd@bsbernd.com>
2025-02-10checkpatch: Disable warning for externs in C filesBernd Schubert-1/+1
We do actually need these, at least for compat.c. Also disable git commit id warnings, these are doing more harm than good (for example trigger long line warnings when fulfilled). Signed-off-by: Bernd Schubert <bernd@bsbernd.com>
2025-02-10Avoid global declarion of internal functions that are new in 3.17Bernd Schubert-34/+44
_fuse_new() is not supposed to be called by external users outside of internal functions or static inlined functions.

2025-02-10Fix junk readdirplus results when filesystem not filling stat infoAmir Goldstein-4/+7
Commit dd95d13a ("fix readdirplus when filler is called with zero offset (#896)) broke readdirplus with passthrough example command: passthrough -o auto_cache,modules=subdir,subdir=/src /mnt The /src directory looks like this: ~# ls -l /src total 0 drwx------ 3 root root 60 Jan 2 17:51 testdir And the fuse directory looks like this: ~# ls -l /mnt total 0 d--------- 0 root root 0 Jan 1 1970 testdir Because readdir_fill_from_list() ignores the fact that filesystem did not pass the FUSE_FILL_DIR_PLUS flag with valid stat info.

As explained in this comment: https://github.com/libfuse/libfuse/pull/896#issuecomment-1978917041 passthrough example needs a few more changes to be able to test commit dd95d13a ("fix readdirplus when filler is called with zero offset (#896)) With the changes in this commit, readdirplus without fill offsets can be tested to verify the readdirplus fix above with command line: passthrough --plus -o auto_cache,modules=subdir,subdir=/src /mnt Signed-off-by: Amir Goldstein <amir73il@gmail.com>
