Some of you may have noticed that OpenSSH in base is lagging far behind
the upstream code.
The main reason for this is the burden of maintaining the HPN patches.
They are extensive, very intrusive, and touch parts of the OpenSSH code
that change significantly in every release. Since they are not
regularly updated, I have to choose between trying to resolve the
conflicts myself (hoping I don't break anything) or waiting for them to
catch up and then figuring out how to apply the new version.
Therefore, I would like to remove the HPN patches from base and refer
anyone who really needs them to the openssh-portable port, which has
them as a default option. I would also like to remove the NONE cipher
patch, which is also available in the port (off by default, just like in
base).
My current employer is a big proponent of HPN (see
http://fasterdata.es.net/data-transfer-tools/scp-and-sftp/). However, I
agree that the difficulty of patching to the changing upstream is
significant. Frankly, I am quite impressed that you have been able to
keep up with it for this long.
I would be more than happy if the HPN patches continued to be in the
port version and base were able to keep up with the upstream by removing
the HPN dependency. There will be some places where we will notice the
difference in performance; in those cases we will install the
HPN-patched port.
