From 9da5c8e200833a957d6221ddcaf900cb3b839c13 Mon Sep 17 00:00:00 2001 From: Peter Powell Date: Thu, 25 Jan 2018 11:51:14 +0000 Subject: Add a module which rehashes SSL modules on receiving SIGUSR1. This has been imported from inspircd-extras where it was known as m_rehashsslsignal. The name has been changed slightly to match the other modules which do SSL stuff (sslmodes, sslinfo). --- src/modules/m_sslrehashsignal.cpp | 64 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 src/modules/m_sslrehashsignal.cpp (limited to 'src') diff --git a/src/modules/m_sslrehashsignal.cpp b/src/modules/m_sslrehashsignal.cpp new file mode 100644 index 000000000..fea32326a --- /dev/null +++ b/src/modules/m_sslrehashsignal.cpp @@ -0,0 +1,64 @@ +/* + * InspIRCd -- Internet Relay Chat Daemon + * + * Copyright (C) 2018 Peter Powell + * Copyright (C) 2016 Attila Molnar + * + * This file is part of InspIRCd.
