Subject: [9fans] intent to delete: devssl, cpu, oexportfs, import
Date: Fri, 22 Oct 2021 19:43:15 -0400	[thread overview]
Message-ID: <8B3ADC2544348BBAA8EFB0A66615C430@eigenstate.org> (raw)

SSL 3.0 is implemented by devssl.  It has been broken
since the POODLE and BEAST attacks in 2014.

However: it's hard-coded in cpu(1), oexportfs(4), and
import(4) via a call to pushssl().  I don't think it's
possible to upgrade them and keep the the protocol
compatible.

To use a working version of the TLS protocol, there's
going to have to be a clean break.  The SSL and TLS
record formats seem incompatible, and there's no
version negotiation in cpu.

9front already deprecated cpu/import, with rcpu and
rimport as replacements, so this only affects 9legacy
to 9front communication.

It'd be nice to keep things interoperable without
patching.

Is there a path forward that doesn't leave us dragging
along a broken, obsolete SSL version forever?
