Robin Sommer updated BIT-1499:
------------------------------
Resolution: Merged (was: Fixed)
Status: Closed (was: Merge Request)
> Updates for newer version of OpenSSL/LibreSSL
> ---------------------------------------------
>
> Key: BIT-1499
> URL: https://bro-tracker.atlassian.net/browse/BIT-1499
> Project: Bro Issue Tracker
> Issue Type: Problem
> Components: Bro, Broccoli
> Affects Versions: git/master
> Reporter: Seth Hall
> Assignee: Robin Sommer
> Fix For: 2.5
>
> Attachments: patch-aux_broccoli_src_bro__openssl.c,
> patch-src_ChunkedIO.cc
>
>
> A comment from Christoph Pietsch:
> {quote}Currently bro fails to build when openssl libraries have been built
> without SSLv3 (configure --no-ssl2 --nossl3). This has
> surfaced when building with the latest LibreSSL 2.3.
> Attached patches address all these issues. These can be improved upon
> by using only SSLv23_ methods or even TLS_ methods and setting
> SSL_CTX_set_options(ctx, SSL_OP_NO_SSL2 | SSL_OP_NO_SSL3) but I've
> tried to make the patches minimally intrusive. OpenSSL 1.1.0 will
> deprecate SSLv23_ methods and introduces compatible TLS_ methods.{quote}
> The patches are attached. Fortunately all of this code is slated to be
> removed but it does introduce the question how we manage this moving forward.
> I'd like to avoid having to add compiler directives to use alternate
> implementations and detect which version of OpenSSL someone has installed.
> Alternately, what does everyone think about deprecating the existing
> communication mechanism by making it a configure-time option? We can just
> not compile those by default which means that almost everyone would just see
> everything work correctly and our effort would be minimal. People that need
> the existing built in communication still can deal with the complications of
> compiling Bro with the option and having the correct version of OpenSSL.
