I have thought about adding filexfer-06 support but every time I go to read the
internet-draft again I am repulsed by all the unnecessary bloat that has crept
in. Not to mention that the filexfer negotiation mechanism requires that we
implement versions 4 and 5 of the protocol too.
We could use an extension to detect this bug, but I recall some discussion on
the working group mailing list that SSH_FXP_INIT extensions were removed because
of incompatibility with filexfer-02 clients.
Therefore, we would need to use a SSH_FXP_EXTENDED packet. This would need an
additional round-trip and would only work for clients that know about the
extension anyway. I also think that it is overkill to do all this to fix a
argument-swapping bug. So I think this solution is pretty useless :(
To avoid breaking deployed software, I think that the only "solution"
is to
leave the bug as it is and fix it if/when we add support for a newer filexfer
version.
