I have added a lot of unpleasant hacks to the code in order to make it
work with NetBSD librefuse. We really should fix it. I will probably
do it later. Release notes from the upstream are as follows:
Release 3.7.2 (2021-06-08)
--------------------------
* Added a secondary check so if a mkdir request fails with EPERM an access request will be
tried - returning EEXIST if the access was successful.
Fixes: https://github.com/libfuse/sshfs/issues/243
Release 3.7.1 (2020-11-09)
--------------------------
* Minor bugfixes.
Release 3.7.0 (2020-01-03)
--------------------------
* New max_conns option enables the use of multiple connections to improve responsiveness
during large file transfers. Thanks to Timo Savola for doing most of the implementation
work, and thanks to CEA.fr for sponsoring remaining bugfixes and cleanups!
* The `buflimit` workaround is now disabled by default. The corresponding bug in OpenSSH
has been fixed in 2007
(cf. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365541#37), so this shouldn't be
needed anymore. If you depend on this workaround, please let the SSHFS maintainers know,
otherwise support for the workaround will be removed completely in a future version.
Release 3.6.0 (2019-11-03)
--------------------------
* Added "-o direct_io" option.
This option disables the use of page cache in kernel.
This is useful for example if the file size is not known before reading it.
For example if you mount /proc dir from a remote host without the direct_io
option, the read always will return zero bytes instead of actual data.
* Added --verbose option.
* Fixed a number of compiler warnings.
* Improved performance under OS X.
Release 3.5.2 (2019-04-13)
--------------------------
* Fixed "-o idmap=user" to map both UID and GID on all OSs.
* Fixed improper handling of sequential spaces spaces in "ssh_command" option
Release 3.5.1 (2018-12-22)
--------------------------
* Documentation updates
* Build system updates
* Added "BindInterface" as valid "-o" option.
Release 3.5.0 (2018-08-28)
--------------------------
* Fixed error code returned by rename(), allowing proper fallback.
* Port to Cygwin.
Release 3.4.0 (2018-06-29)
--------------------------
* Make utimens(NULL) result in timestamp "now" -- no more touched files
dated 1970-01-01
* New `createmode` workaround.
* Fix `fstat` workaround regression.
Release 3.3.2 (2018-04-29)
--------------------------
* New `renamexdev` workaround.
Release 3.3.1 (2017-10-25)
--------------------------
* Manpage is now installed in correct directory.
* SSHFS now supports (or rather: ignores) some options that it may
receive as result of being mounted from ``/etc/mtab``. This includes
things like ``user``, ``netdev``, or ``auto``.
SSHFS 3.3.0 (2017-09-20)
------------------------
* Dropped support for writeback caching (and, as a consequence,
"unreliable append" operation). As of kernel 4.14, the FUSE module's
writeback implementation is not compatible with network filesystems
and there are no imminent plans to change that.
* Add support for mounting from /etc/fstab
* Dropped support for building with autotools.
* Added missing options to man page.
Release 3.2.0 (2017-08-06)
--------------------------
* Re-enabled writeback cache.
* SSHFS now supports O_APPEND.
Release 3.1.0 (2017-08-04)
--------------------------
* Temporarily disabled the writeback cache feature, since there
have been reports of dataloss when appending to files when
writeback caching is enabled.
* Fixed a crash due to a race condition when listing
directory contents.
* For improved backwards compatibility, SSHFS now also silently
accepts the old ``-o cache_*`` options.
Release 3.0.0 (2017-07-08)
--------------------------
* sshfs now requires libfuse 3.1.0 or newer.
* When supported by the kernel, sshfs now uses writeback caching.
* The `cache` option has been renamed to `dir_cache` for clarity.
* Added unit tests
* --debug now behaves like -o debug_sshfs, i.e. it enables sshfs
debugging messages rather than libfuse debugging messages.
* Documented limited hardlink support.
* Added support for building with Meson.
* Added support for more SSH options.
* Dropped support for the *nodelay* workaround - the last OpenSSH
version for which this was useful was released in 2006.
* Dropped support for the *nodelaysrv* workaround. The same effect
(enabling NODELAY on the server side *and* enabling X11 forwarding)
can be achieved by explicitly passing `-o ForwardX11`
* Removed support for `-o workaround=all`. Workarounds should always
enabled explicitly and only when needed. There is no point in always
enabling a potentially changing set of workarounds.
Release 2.9 (2017-04-17)
------------------------
* Improved support for Cygwin.
* Various small bugfixes.
Release 2.8 (2016-06-22)
------------------------
* Added support for the "fsync" extension.
* Fixed a build problem with bitbake
* Integrated osxfuse's copy of sshfs, which means that sshfs now works
on OS X out of the box.
* Added -o cache_max_size=N option to let users tune the maximum size of
the cache in number of entries.
* Added -o cache_clean_interval=N and -o cache_min_clean_interval=N
options to let users tune the cleaning behavior of the cache.
This is a filesystem client based on the SSH File Transfer Protocol.
Since most SSH servers already support this protocol it is very easy to
set up: i.e. on the server side there's nothing to do. On the client
side mounting the filesystem is as easy as logging into the server with
ssh.
The idea of sshfs was taken from the SSHFS filesystem distributed with
LUFS. There were some limitations in that codebase, and this
implementation features:
- Based on FUSE
- Multithreading
- Large reads (max 64k)
- Caching directory contents
- Reconnect on failure
