From bd12e3a4e6501496f6eeb7aeb5245162020d6e6c Mon Sep 17 00:00:00 2001 From: danieldg Date: Sat, 14 Mar 2009 20:48:43 +0000 Subject: Extban rework: allow exceptions to override bans on join Move all bans that prevent a user from joining the channel to OnCheckBan, then stack their return results to allow an exception to override a ban. This does not make join exceptions override any other exception like mute. git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@11222 e03df62e-2008-0410-955e-edbf42e46eb7 --- src/modules/m_allowinvite.cpp | 2 +- src/modules/m_banexception.cpp | 3 ++- src/modules/m_blockcaps.cpp | 2 +- src/modules/m_blockcolor.cpp | 2 +- src/modules/m_channelban.cpp | 20 +++++--------------- src/modules/m_gecosban.cpp | 18 +++--------------- src/modules/m_muteban.cpp | 4 ++-- src/modules/m_noctcp.cpp | 2 +- src/modules/m_nokicks.cpp | 2 +- src/modules/m_nonicks.cpp | 2 +- src/modules/m_nonotice.cpp | 2 +- src/modules/m_nopartmsg.cpp | 2 +- src/modules/m_operchans.cpp | 28 +++++++--------------------- src/modules/m_operinvex.cpp | 18 ++++-------------- src/modules/m_serverban.cpp | 18 +++--------------- src/modules/m_services_account.cpp | 22 ++++++++++------------ src/modules/m_stripcolor.cpp | 2 +- 17 files changed, 45 insertions(+), 104 deletions(-) (limited to 'src/modules') diff --git a/src/modules/m_allowinvite.cpp b/src/modules/m_allowinvite.cpp index a675a0cc8..cbab0bd2f 100644 --- a/src/modules/m_allowinvite.cpp +++ b/src/modules/m_allowinvite.cpp @@ -44,7 +44,7 @@ class ModuleAllowInvite : public Module { if (IS_LOCAL(user)) { - if (channel->IsModeSet('A') && !channel->IsExtBanned(user, 'A')) + if (channel->IsModeSet('A') && channel->GetExtBanStatus(user, 'A') < 0) { // Explicitly allow /invite return -1;
