Hello, Also, sprach Miklos Szeredi am Freitag, den 29. Dezember 2006 um 15:11: > OK, that implicates fuse, rather than sshfs. The following patch > removes an unalinged access in that part of the code. Can you > please try compiling fuse with this patch?
I applied the patch to the fuse source (retrieved via apt-get source
fuse, version is 2.5.3-4.1) like this:
$ patch -p0 < /home/smc/fuse.diff
patching file lib/mount.c
Hunk #1 succeeded at 133 with fuzz 2 (offset -20 lines).
Hunk #2 succeeded at 163 with fuzz 1 (offset -20 lines).
The applied patches look correct nevertheless. I then built the
package with
$ dpkg-buildpackage -b -rfakeroot -us -uc
and installed the debs for fuse-utils and libfuse2 (libfuse-dev was
not installed and if I am not completely mistaken is irrelevant either
way).
I repeated the gdb steps but the same errors (bus access error,
mountpoint unusable and has weird permissions) and kernel messages
(see below), and the output looks conspicuously the same (n.b.: to be
absolutely sure I restarted the machine first):
$ gdb sshfs

The kernel, again, prints this:

At least fusermount -u works as expected :)
Greetings and thanks for the quick response!
