Description Dmitrij Tejblum 2010-08-15 15:00:04 UTC 
At early days of FreeBSD 8.x a field named `fo_truncate' was added `struct fileops' in sys/file.h, and ftruncate() syscall was made to use it. FUSE module has its own instance of `struct fileops', but it was not adapted to this change. 
(It seems that FreeBSD 7.x and earlier aren't affected by this bug.)

Fix: The attached patch can be added to the files/ directory of the sysutils/fusefs-kmod port as patch-fuse_module__fuse_main.c

Patch attached with submission follows:
How-To-Repeat: On a FUSE filesystem (e.g. ntfs-3g) do
dd if=/dev/zero count=1 oseek=1000000 of=SOMEFILE
The system will panic.

Worked on my 8.1-REL system too, like a charm!

I can use sshfs now again, what a relief.

I will also try this on 9-CURRENT.

Greetings,
