From 27594eeae6f40a402bc3110f06d57975168e74e3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Thu, 4 Jun 2015 19:20:15 +0200 Subject: ics-openvpn as a submodule! beautiful ics-openvpn is now officially on GitHub, and they track openssl and openvpn as submodules, so it's easier to update everything. Just a git submodule update --recursive. I've also set up soft links to native modules from ics-openvpn in app, so that we don't copy files in Gradle (which was causing problems with the submodules .git* files, not being copied). That makes the repo cleaner. --- app/openssl/ssl/tls_srp.c | 533 ---------------------------------------------- 1 file changed, 533 deletions(-) delete mode 100644 app/openssl/ssl/tls_srp.c (limited to 'app/openssl/ssl/tls_srp.c') diff --git a/app/openssl/ssl/tls_srp.c b/app/openssl/ssl/tls_srp.c deleted file mode 100644 index e7368a8f..00000000 --- a/app/openssl/ssl/tls_srp.c +++ /dev/null @@ -1,533 +0,0 @@ -/* ssl/tls_srp.c */ -/* Written by Christophe Renou (christophe.renou@edelweb.fr) with - * the precious help of Peter Sylvester (peter.sylvester@edelweb.fr) - * for the EdelKey project and contributed to the OpenSSL project 2004. - */ -/* ==================================================================== - * Copyright (c) 2004-2011 The OpenSSL Project.
