 SSHFS does not have any active, regular contributors or developers. The current maintainer continues to apply pull requests and tries to make regular releases, but unfortunately has no capacity to do any development beyond addressing high-impact issues. When reporting bugs, please understand that unless you are including a pull request or are reporting a critical issue, you will probably not get a response.

-To prevent the issue tracker from being flooded with issues that no-one is intending to work on, and to give more visibilty to critical issues that users should be aware of and that most urgently need attention, I will also close most bug reports once they've been inactive for a while.
+To prevent the issue tracker from being flooded with issues that no-one is intending to work on, and to give more visibility to critical issues that users should be aware of and that most urgently need attention, I will also close most bug reports once they've been inactive for a while.

 Please note that this isn't meant to imply that you haven't found a bug - you most likely have and I'm grateful that you took the time to report it. Unfortunately, SSHFS is a purely volunteer driven project,
 and at the moment there simply aren't any volunteers.

+# SSHFS
+
+
+## About
+
+SSHFS allows you to mount a remote filesystem using SFTP. Most SSH
+servers support and enable this SFTP access by default, so SSHFS is
+very simple to use - there's nothing to do on the server-side.
+
+
+## Development Status
+
+
+SSHFS is shipped by all major Linux distributions and has been in
+production use across a wide range of systems for many years. However,
+at present SSHFS does not have any active, regular contributors, and
+there are a number of known issues (see the [bugtracker](https://github.com/libfuse/sshfs/issues)).  
+The current maintainer continues to apply pull requests and makes regular
+releases, but unfortunately has no capacity to do any development
+beyond addressing high-impact issues. When reporting bugs, please
+understand that unless you are including a pull request or are
+reporting a critical issue, you will probably not get a response.
+
+
+## How to use
+
+
+Once sshfs is installed (see next section) running it is very simple:
+
+```
+sshfs [user@]hostname:[directory] mountpoint
+```
+
+It is recommended to run SSHFS as regular user (not as root).  For
+this to work the mountpoint must be owned by the user.  If username is
+omitted SSHFS will use the local username. If the directory is
+omitted, SSHFS will mount the (remote) home directory.  If you need to
+enter a password sshfs will ask for it (actually it just runs ssh
+which asks for the password if needed).
+
+Also many ssh options can be specified (see the manual pages for
+*sftp(1)* and *ssh_config(5)*), including the remote port number
+(`-oport=PORT`)
+
+To unmount the filesystem:
+
+```
+fusermount -u mountpoint
+```
+
+On BSD and macOS, to unmount the filesystem:
+
+```
+umount mountpoint
+```
+
+### Bypassing SSH
+
+#### Using directport
+
+Using direct connections to sftp-server to bypass SSH for performance is also possible. To do this, start a network service using sftp-server (part of OpenSSH) on a server, then connect directly using `-o directport=PORT` option.
+
+On server (listen on port 1234 using socat):
+
+`socat tcp-listen:1234,reuseaddr,fork  exec:/usr/lib/openssh/sftp-server`
+
+On client:
+
+`sshfs -o directport=1234 127.0.0.1:/tmp /tmp/mnt`
+
+Note that this is insecure as connection will happen without encryption. Only use this on localhost or trusted networks. This option is sometimes used by other projects to mount folders inside VMs.
+
+IPv6 is also possible:
+
+`socat tcp6-listen:1234,reuseaddr,fork exec:/usr/lib/openssh/sftp-server`
+
+`sshfs -o directport=1234 [::1]:/tmp /tmp/mnt`
+
+#### Using vsock
+
+Similarly to above, Linux [vsock](https://man7.org/linux/man-pages/man7/vsock.7.html) can be used to connect directly to sockets within VMs using `-o vsock=CID:PORT`.
+
+```
+# on the host
+socat VSOCK-LISTEN:12345 EXEC:"/usr/lib/openssh/sftp-server",nofork
+# on the clientside
+sshfs -o vsock=2:12345 unused_host: ./tmp
+```
+
+## Installation
+
+
+First, download the latest SSHFS release from
+https://github.com/libfuse/sshfs/releases. You also need [libfuse](http://github.com/libfuse/libfuse) 3.1.0 or newer (or a
+similar library that provides a libfuse3 compatible interface for your operating
+system). Finally, you need the [Glib](https://developer.gnome.org/glib/stable/) library with development headers (which should be
+available from your operating system's package manager).
+
+To build and install, we recommend to use [Meson](http://mesonbuild.com/) (version 0.38 or
+newer) and [Ninja](https://ninja-build.org/).  After extracting the sshfs tarball, create a
+(temporary) build directory and run Meson:
+
+```
+$ mkdir build; cd build
+$ meson ..
+```
+
+Normally, the default build options will work fine. If you
+nevertheless want to adjust them, you can do so with the *mesonconf*
+command:
+
+```
+$ mesonconf                  # list options
+$ mesonconf -D strip=true    # set an option
+```
+
+To build, test and install SSHFS, you then use Ninja (running the
+tests requires the [py.test](http://www.pytest.org/) Python module):
+
+```
+$ ninja
+$ python3 -m pytest test/    # optional, but recommended
+$ sudo ninja install
+```
+

+mailing list (subscribe at

- * Option description
- *
- * This structure describes a single option, and and action associated
- * with it, in case it matches.
- *
- * More than one such match may occur, in which case the action for
- * each match is executed.
- *
- * There are three possible actions in case of a match:
- *
- * i) An integer (int or unsigned) variable determined by 'offset' is
- *    set to 'value'
- *
- * ii) The processing function is called, with 'value' as the key
- *
- * iii) An integer (any) or string (char *) variable determined by
- *    'offset' is set to the value of an option parameter
- *
- * 'offset' should normally be either set to
- *
- *  - 'offsetof(struct foo, member)'  actions i) and iii)
- *
- *  - -1                              action ii)
- *
- * The 'offsetof()' macro is defined in the <stddef.h> header.
- *
- * The template determines which options match, and also have an
- * effect on the action.  Normally the action is either i) or ii), but
- * if a format is present in the template, then action iii) is
- * performed.
- *
- * The types of templates are:
- *
- * 1) "-x", "-foo", "--foo", "--foo-bar", etc.  These match only
- *   themselves.  Invalid values are "--" and anything beginning
- *   with "-o"
- *
- * 2) "foo", "foo-bar", etc.  These match "-ofoo", "-ofoo-bar" or
- *    the relevant option in a comma separated option list
- *
- * 3) "bar=", "--foo=", etc.  These are variations of 1) and 2)
- *    which have a parameter
- *
- * 4) "bar=%s", "--foo=%lu", etc.  Same matching as above but perform
- *    action iii).
- *
- * 5) "-x ", etc.  Matches either "-xparam" or "-x param" as
- *    two separate arguments
- *
- * 6) "-x %s", etc.  Combination of 4) and 5)
- *
- * If the format is "%s", memory is allocated for the string unlike
- * with scanf().

Abhinav Agarwal	29bb565ea6	reject hostname option injection via bracketed mount source A source like [-oProxyCommand=CMD]:/path passes the bracket-parsing check in find_base_path() and ends up as -oProxyCommand=CMD in the ssh argv. When sftp_server is a path, ssh gets a destination argument and executes the injected ProxyCommand before connecting. Reject hostnames starting with - after bracket stripping, and add -- before the hostname in the ssh command line so positional args can't be misread as options.	2026-05-29 16:00:27 -07:00

Abhinav Agarwal	bcd132f17c	add contain_symlinks option to prevent symlink escape attacks A malicious SFTP server can return symlink targets that the local kernel VFS resolves outside the mount root, enabling local file reads or writes through ordinary operations like cp following a symlink. Add a contain_symlinks option (default on) that rejects absolute symlink targets and any target containing a `..` component, returning EPERM. Users who need legacy pass-through for trusted servers can opt out with -o no_contain_symlinks. The check is purely lexical and deliberately strict: in an adversarial filesystem the server controls intermediate path components, so any non-`..` component could be a symlink anywhere, making lexical depth tracking unreliable. Rejecting absolute and any `..` is the simplest rule that is provably complete against the threat model. transform_symlinks composes poorly with containment because transformed results often contain `..`; a warning is emitted when both are enabled. Tests cover default-on containment (readlink + open/stat traversal), opt-out behavior, transform_symlinks interaction (both arms), and option precedence.	2026-05-29 15:54:21 -07:00

Jan Palus	5f767dec5b	Fill stat info when returning cached data for readdir Uncached and cached results for readdir were inconsistent -- the former returned correct stat info for directory entries while the latter didn't. That's because only names of entries were saved in cache without stat info. In turn this leads to issues like https://github.com/junegunn/fzf/issues/3832 since directory traversal library (https://github.com/charlievieth/fastwalk in this case) relies on proper stat info returned by readdir. Hence when unchached result was returned it gave proper outcome, while with cached result it was wrong. Cache stat info next to entry name to fix the issue. While file attributes are saved in cache already, they use full path as key. To avoid potentially plenty of allocations, string copying and cache lookups to get each attr, let's keep a copy of stat struct independently to be on the fast path.	2024-06-17 11:48:44 +02:00
