Goldstein Lyor updated SSHD-400:
--------------------------------
Description:
According to the [specification](see
https://filezilla-project.org/specs/draft-ietf-secsh-filexfer-02.txt) - section
4 - Protocol Initialization - the _SSH_FXP_INIT_ message may contain optional
extension strings and "Implementations MUST silently ignore any extensions
whose name they do not recognize.".
While such extensions may be rare, IMO we don't want the SSHD server to fail
talking to such clients. Attached is a patch in that spirit (BTW, there was
also a logging error - the message was logging the received version *before*
the value was initialized...)
