[fuse-devel] Crash

[Ricardo C. <sou...@wi...>]

Hi,

One of my users is having a problem where he runs 'find' on the filesystem, 
interrupts it with CTRL-C and the filesystem crashes with a double free() or 
with a segfault. I have not been able to reproduce this, though.

He is using FUSE-2.5.3, SMP kernel 2.6.19, Debian Etch (4.0).

The backtraces appear to be messed up but they seem to point to the FUSE 
library. The last stack frame was in fuse_reply_none() which, AFAICS, is only 
being called by the default fuse_forget() (my filesystem isn't using 
the "forget" operation).

I have asked him to run the filesystem under valgrind, but in the mean time I 
have a question. I suspect this could be the problem, but I'm not sure. This 
is what I'm doing for almost every operation:

int error = -fuse_reply_xxx(req, ...);
if(error)
	fuse_reply_err(req, error);

Is this valid usage, considering possible errors in sending the replies?

Thanks.
