From 25b2354cc9bcf09c87dc65526936e976fe95d3fd Mon Sep 17 00:00:00 2001 From: Ingela Anderton Andin Date: Fri, 3 Feb 2012 14:06:53 +0100 Subject: User defined verify_fun is now called correctly Background from erlang-questions: > We use this test suite to verify our PKIX-path-validation code, > granted we do not yet support CRL-handling but that is on its > way. Our verify_fun will let you work around the problem that it > is not yet supported. (Not so fun for you perhaps but a possible > solution for now). this is unfortunately not the case since for versions that contain commit 4dbf3c9e4ae7cfd19b247353369166d31b8f15e5 (it is in R14B04 and R15B) the documented behaviour (verify_fun will be called for every certificate) is broken: the verify_fun will only be called, if the certificate contains unknown extensions. it is therefore not useful as a CRL workaround (anymore). best regards Stefan Grundmann --- lib/ssl/src/ssl_handshake.erl | 17 ++++--- lib/ssl/test/ssl_basic_SUITE.erl | 103 ++++++++++++++++++++++++++++++++++++++- 2 files changed, 112 insertions(+), 8 deletions(-) (limited to 'lib') diff --git a/lib/ssl/src/ssl_handshake.erl b/lib/ssl/src/ssl_handshake.erl index 371f475c85..542033e6ce 100644 --- a/lib/ssl/src/ssl_handshake.erl +++ b/lib/ssl/src/ssl_handshake.erl @@ -1,7 +1,7 @@ %% %% %CopyrightBegin% %% -%% Copyright Ericsson AB 2007-2011.
