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/d1_srtp.c | 463 ---------------------------------------------- 1 file changed, 463 deletions(-) delete mode 100644 app/openssl/ssl/d1_srtp.c (limited to 'app/openssl/ssl/d1_srtp.c') diff --git a/app/openssl/ssl/d1_srtp.c b/app/openssl/ssl/d1_srtp.c deleted file mode 100644 index 535539ba..00000000 --- a/app/openssl/ssl/d1_srtp.c +++ /dev/null @@ -1,463 +0,0 @@ -/* ssl/t1_lib.c */ -/* Copyright (C) 1995-1998 Eric Young (eay@cryptsoft.com) - * All rights reserved. - * - * This package is an SSL implementation written - * by Eric Young (eay@cryptsoft.com). - * The implementation was written so as to conform with Netscapes SSL. - * - * This library is free for commercial and non-commercial use as long as - * the following conditions are aheared to.
