The rustls project, initially wanting to stay backward compatible to the v0.10.x API, has change its mind and no longer guarantees any stability in future versions. In fact, they have changed the API already, making mod_tls no longer viable. I personally do not have the time to chase after this. If no one else has interests (and I don't know of anyone using it - else, speak up), I propose to remove it from the 2.4.x branch again. Kind Regards, Stefan I am +1 for that, I have looked to arrange the testsuite to test mod_ssl instead mod_ssl via pytest in trunk (PR: https://github.com/apache/httpd/pull/433) so I would like to keep mod_tls in trunk if possible (but I am NOT planning to work on mod_tls for the moment). -- Cheers Jean-Frederic

Since the existing mod_tls is provided under ALv2, then no additional paperwork should be required. We are merely using that code under the license provided. The real question is whether the files to be imported into our repository have headers that specify copyright held by others. For that, we need to get the copyright owners' approval to replace that with our standard header. https://www.apache.org/legal/src-headers.html (if we want to change them; we could simply copy from upstream, or change if the locus of development is our repository) There is likely some other page talking about permission to switch out the copyright header, but I don't have that link handy.

Re: mod_tls as experimental module?
Thanks everyone for giving feedback. I summarise this as an overall positive response. I will start next week on bringing this over as an experimental module. Also make the test cases run on one of our travis instances. Additionally, we need to clarify with ASF and ISRG if this needs some sort of paperwork. Since the ISRG repository uses the Apache license, in my naive world view, this should be quite an informal process. But I do not really know. It would be great, if there is any formality here, for someone else to drive this. I have mixed roles here as the author, contractor for ISRG and httpd pmc member. Joe: any advice?

I looked at the code diagonally and it looks good to me (I like it and the safety guarantees of rust), thanks for the good work! +1 for experimental which will give us some margin. However what would be a discussion without a naming dispute, mod_rustls? :p (no strong opinion of course..). Cheers; Yann.

RE: mod_tls
The referrence here is one about all the filters used by apache 2.0. If there is a filter bucket in APR, it's understandable that Apache 2.0 modules will have 2 parts. The logic piece and the filter piece. As far as I can tell, the filter mechanism allows for some distinct advantages and makes for a very flexible configuration framework. My issue here is that if mod_tls is sacrificed, then what's the point of using filters at all anyway? That said, could it be said that you CAN write a module for Apache 2.0 without needing the use of filters? If so, then that makes sense. -- Austin Gonyou Systems Architect, CCNA Coremetrics, Inc.

RE: mod_tls
In 1.3.x, it was so happening that Apache/mod_ssl registers the connection id (fd) with OpenSSL, and then OpenSSL takes over the connection handling as well as the protocol communication stuff from that point onwards.. In 2.x, with the introduction of filters, OpenSSL nolonger talks directly to the client directly.. Instead, all the data comes/goes thru' the filters (*_NETWORK_*).. The connection handling stuff is done at the APR level.. Thus, the OpenSSL is used only for the protocol logic ONLY and not for handling any connection details..

What would be lost if those filters don't exist. And, what was the need to put them in, originally. thanks, sunitha Gonyou, Austin wrote: The referrence here is one about all the filters used by apache 2.0. If there is a filter bucket in APR, it's understandable that Apache 2.0 modules will have 2 parts. The logic piece and the filter piece. As far as I can tell, the filter mechanism allows for some distinct advantages and makes for a very flexible configuration framework. My issue here is that if mod_tls is sacrificed, then what's the point of using filters at all anyway? That said, could it be said that you CAN write a module for Apache 2.0 without needing the use of filters? If so, then that makes sense.

Kewl. Less maintenance all around. Is the entire filter scheme doomed like this though? -- Austin Gonyou Systems Architect, CCNA Coremetrics, Inc.

You don't need mod_tls to use mod_ssl. Either mod_ssl needs to get the logic stripped out and it needs to be hooked in to mod_tls (and the fixes from mod_ssl need to get shifted over to mod_tls), or mod_tls needs to go away.

Re: mod_tls
Probably, but renames are a PITA. Ryan On Thursday 23 August 2001 09:47, MATHIHALLI,MADHUSUDAN (HP-Cupertino,ex1) wrote: Ok.. So, what you mean is to have 2 modules - (1). mod_ssl to implement the HTTPS stuff, and (2). mod_tls which does just the SSL filtering. That's great !!.. So, in that case, is it worthwhile to rename mod_tls to something like ssl_filter and mod_ssl to mod_https ?..

Both mod_tls and mod_ssl are capable of SSL TLS protocol comm., and they both use the same utility (OpenSSL) for achieving it.. (AFAIK, mod_ssl goes a step further by being compatible with SSL-C). The only reason why mod_tls has to be maintained (if at all) is because it's a lot simple to understand and easier to manipulate..
