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/crypto/asn1/x_name.c | 519 --------------------------------------- 1 file changed, 519 deletions(-) delete mode 100644 app/openssl/crypto/asn1/x_name.c (limited to 'app/openssl/crypto/asn1/x_name.c') diff --git a/app/openssl/crypto/asn1/x_name.c b/app/openssl/crypto/asn1/x_name.c deleted file mode 100644 index d7c23186..00000000 --- a/app/openssl/crypto/asn1/x_name.c +++ /dev/null @@ -1,519 +0,0 @@ -/* crypto/asn1/x_name.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.
