Sergei and other maintainers,

IANAL, but I don't think that the PolarSSL FOSS exception is that useful
in the eCos context - eCos itself might be OK is my read - but certainly
not any developer's proprietary embedded application that it is linked
with. I think you should carefully consider the licensing aspects here
before making this an official eCos project.

Regards, Paul.

That was a weekend hack only. As far I call correctly the porting
process was straightforward, that GPL PolarSSL version had a few I/O
stubs to overwrite and I have got HTTPS connection on eCos synthetic
target.  I had no further work with PolarSSL (and SSL for eCos) but,
IMHO, the project was very promising SSL project ... and IT IS as

thanking your e-mail I knew that PolarSSL team became to provide FOSS
License Exception

  https://polarssl.org/foss-license-exception

IANAL, but it looks like that we would use GPL PolarSSL 2.0 with that
FOSS exception in eCos. If this so, you would register new eCos project

  http://ecos.sourceware.org/contrib.html

open eCos Bugzilla entry (http://bugs.ecos.sourceware.org) for the port
and I hope you will find more hands for porting process then. But before
to start I would get confirmation that PolarSSL FOSS License exception
does cover the eCos License exception.

Paul, thank you for clarification, I understood your point (which I did
miss) I will make a references on this thread (your warning) on the eCos
discuss list.
