I have a binary running on a fuse filesystem which is generating a zip file. I don't know what syscalls are involved since the binary segfaults when run with strace. After doing a binary search, https://github.com/torvalds/linux/commit/fa5eee57e33e79b71b40e6950c29cc46f5cc5cb7 is the commit that seems to have introduced the error. It still seems to failing with a much newer kernel. Reverting the fuse_invalidate_attr_mask in fuse_perform_write to fuse_invalidate_attr makes every other run of the binary produce the correct output. I found that enabling the writeback cache makes the binary always produce the right output. Running the fuse daemon in single threaded mode also works. Is there anything that sticks out to you that is wrong with the above commit? Thanks, Frank Dinoff
