Sorry for not replying earlier, but missed the time.
Thanks for your interest. Say, have you also followed #67? For general information about status of GSI-OpenSSH in the GCT, please have a look at this thread which extends over more than half a year. Please also feel free to subscribe to this list and participate in the discussions.

Please correct if I'm wrong somewhere in the following. Quite some time has already passed since we last discussed this.
AFAIR we'd like to drop the HPN-SSH (and iSSHD) patches for the GCT to keep GSI-OpenSSH in the GCT simple and compatible with the version in EPEL/Fedora. HPN-SSH is nice but the GCT also offers GridFTP which is much better suited for high-performance file transfers, although HPN-SSH has the advantage to enable well-known tools like scp
/sftp
to yield good file transfer performance on WANs and LANs, which is tempting for users.
Back to GSI-OpenSSH in the GCT: Since the start of the GCT the "shipped" (quoted because up until #63 the OpenSSH source code and additional patches were downloaded from external sources on the fly during build) GSI-OpenSSH beame outdated. It's still based on OpenSSH Portable 7.5p1 . As our main target OS is RHEL (and compatible Linux distributions) and Mattias Ellert already provides up to date versions of GSI-OpenSSH for these via EPEL/Fedora based on the maintained OpenSSH version of the respective OS release - so most users can just install a maintained version of GSI-OpenSSH on their RHEL compatible OS - the outdated GSI-OpenSSH in the GCT is actually not as bad as it might look. hence also not much effort went into fixing that situation.
Back to your request: As we'd like to drop the HPN-SSH patches, I'm unsure how we could combine our efforts. Maybe we can reconsider if we'd know what the perspective of your patches are:
- How long do you plan to support these?
- Will you forward-port the patches to current OpenSSH versions?
- Will you rebase your patches on the latest HPN-SSH patches from SourceForge?
But there could still be a big obstacle ahead: I seem to also remember that the HPN-SSH patches aren't compatible with the OpenSSH patches used by EPEL/Fedora. So they might not be combined.

I apologize for the late reply.
Thank you for your polite explanation of current status. I understood the status.
Since we have used the GSI-OpenSSH provided by globus.org so far, we updated GSI-OpenSSH without dropping the features such as the HPN-SSH and iSSHD. However, we do not mean to strongly need those features. Personally, I think that the HPCI should move to use the GSI-OpenSSH in the GCT.
We would like to contribute to the GCT in another way.
Thank you.

Fixed with #108.
