Keith Buck 77d3d2dbaf Remove s_assert definition from ircd_defs.h and add it to its own header.
s_assert requires some higher-level functionality that shouldn't be
present in ircd_defs.h. ircd_defs.h is used by ssld, which has no notion
of logging or sending IRC messages. Additionally, some of the headers
s_assert depends on result in conflicting definitions in ssld.c.

This change also fixes the compile when using --enable-assert=soft.

Jilles Tjoelker 35bfe0e644 join: Fix messages about join failures such as banned.
This was broken by 6f7b36d5d0 in February
2013, as join failures are the only situation where a non-trivial
numeric is passed through from other code to be sent to a client. Fix it
by porting more code from ircd-ratbox 3.1.

Jilles Tjoelker 373a04393b kill: Improve comment about kill hook. 2013-04-27 16:55:45 +02:00
Elizabeth Myers 9d745dbd21 Implement kill-cancelling hook.
With this comes an example module to block the killing of services.

NOTE: this will not cancel remote kills. Those are still accepted, per
the TS 6 specification.

Alex Iadicicco fda96b89dc m_nick: Reject nicks with '~' in them, rather than cutting at the '~'
The behavior of cutting at the first '~' is confusing at first, and
looks too much like a bug.

Jilles Tjoelker ce782b68fe Don't send ERR_NICKCOLLISION to a user that will not be killed. 2013-03-23 22:57:28 +01:00
William Pitcock 6f7b36d5d0 Mostly enable support for checking format strings with -Wformat.
Basically derived from Ratbox 3.1.

Jilles Tjoelker e0c7937a9f UID/EUID: Add server's SID to invalid UID error message. 2013-02-03 20:31:52 +01:00
Jilles Tjoelker 561d7efc44 UID/EUID: Check that the UID starts with the server's SID.
If not, the local link that sent the command is broken, as with
syntactically invalid UIDs.

William Pitcock f30a5ee4c4 Remove MODE_NOCTCP from core, in favor of chm_noctcp. 2012-03-31 22:48:36 -05:00
William Pitcock 67aeaba593 Remove MODE_NOCOLOR from core, replacing it with modules/chm_nocolour.so. 2012-03-31 22:26:45 -05:00
William Pitcock 6eb033605c Check for empty string after permutation hooks have run. 2012-03-31 22:18:15 -05:00
William Pitcock ca4c2a86ee Add support for hookifying PRIVMSG/NOTICE.
This will allow us to modularize message processing, e.g. having new modules to manipulate
channel and private messages in new ways.

Yes: it can be used to intercept messages, but such modules are already out in the wild for
charybdis anyway -- so this doesn't really change anything there.

If you are changing the text, then it is your responsibility to provide a pointer to a new
buffer.  This buffer should be statically allocated and stored in your module's BSS segment.
We will not, and cannot, free your buffer in core, so dynamically allocated buffers will
cause a memory leak.

This will allow us to simplify m_message considerably, by moving channel mode logic out to
their own modules.

Keith Buck 2d537cae88 Remove unused variable cruft. 2012-03-25 02:37:41 +00:00
Jilles Tjoelker 494d2b9dd4 Apply special CTCP handling to messages to @/+ channel as well:
* +C cmode blocks CTCPs
 * CTCPs to large channels relax some flood protection to allow all
   answers through.
2012-03-14 23:20:05 +01:00
Jilles Tjoelker 60dd1febe2 Apply colour stripping (cmode +c) to messages to @/+ channel as well. 2012-03-14 23:04:30 +01:00
Jilles Tjoelker d1316b193b Keep forward channels in sync after a netjoin.
Arbitrarily prefer a forward channel to no forward channel and an
alphabetically higher forward channel to a lower one.

This is a simplistic implementation that generates one MODE message to
local clients for each ban removed (to be replaced).

For simplicity and to avoid amplification of incoming MODE messages,
regular modes may still desync the forward channel of a ban.

Keith Buck 7e132ff005 ratelimit: Add rate-limiting to MOTD, WHO, and remote WHOIS. 2012-02-18 03:56:47 +00:00
Jilles Tjoelker c25a890796 Remove some TS5 code from ms_bmask().
ms_bmask() used to send MODE messages to TS5 servers, but
TS5 support was removed long ago.
2012-02-17 00:36:12 +01:00
Jilles Tjoelker 23f6b63af6 Send forward channel when bans are added/removed because of TS/bursts.
If a netburst adds bans or a channel TS change removes bans, +b/-b modes
are generated. Make sure these contain the forward channel, if any.

This appears also broken in ircd-seven.

William Pitcock 806402515b m_server: make sure required_caps is non-zero. 2012-02-04 04:39:39 -06:00
William Pitcock 79d488b283 m_server: reenable required cap negotiation 2012-02-04 02:03:52 -06:00
William Pitcock 346fba9252 Migrate capability negotiation code to new dynamic capability management API.
This needs a lot of testing, obviously.
2012-02-04 01:47:46 -06:00
Jilles Tjoelker 97532cfafb Fix assertion failure when failing to join a channel and there is no forward.
This was harmless apart from the message.
2012-01-08 16:41:26 +01:00
Jilles Tjoelker d9af501aa8 Fix a warning about const with forward channels. 2012-01-08 16:23:18 +01:00
William Pitcock b583faf970 Add support for customizing the usable nick length.
This adds a new ISUPPORT token, NICKLEN_USABLE which is strictly an informative value.
NICKLEN is always the maximum runtime NICKLEN supported by the IRCd, as other servers may
have their own usable NICKLEN settings.  As NICKLEN_USABLE is strictly informative, and
NICKLEN is always the maximum possible NICKLEN, any clients which depend on NICKLEN for
memory preallocation will be unaffected by runtime changes to NICKLEN_USABLE.

The default NICKLEN is 50; the default serverinfo::nicklen in the config file is set to
30, which is the NICKLEN presently used on StaticBox.

Jilles Tjoelker 0cce01d388 Fix -Wformat errors found in ircd-ratbox.
We cannot use -Wformat meaningfully but ircd-ratbox trunk can.

Jilles Tjoelker 6a85e665db If use_forward=no, ignore any forwarding for joins by local users. 2011-09-25 17:26:01 +02:00
Jilles Tjoelker 2da6f6ebd7 Put back use_forward. 2011-09-25 16:22:29 +02:00
Elizabeth Jennifer Myers 765d839d3c Port ircd-seven banfowards to charybdis.
nenolod gave the thumbs-up to port ircd-seven banfowards to charybdis to spb
for a while, and people have asked about it. Might as well do it since it's a
slow weekend.

Note that as a side effect use_forward is removed from the config and
unconditionally enabled!

Elizabeth Jennifer Myers 7eec45bc9d Back out chanroles.
While what chanroles are trying to accomplish is a good idea, it is
apparently unclear this is the proper way to do it. Until we figure out
the exact way we wish to do this, it should be reverted for now.
2011-07-07 21:24:14 -04:00
Elizabeth Jennifer Myers 8aabb973c0 Implement chanroles, as discussed with nenolod.
The theory behind this is that services sends an ENCAP * GRANT #channel
UID :+flagspec message specifying the chanroles the user has. They are
mapped into flag bits and applied to the membership of the user. They
then are restricted or permitted to what they can do based on the
permissions mask regardless of rank.

For backwards compatibility, the default permission bit (without a GRANT
statement) allows a user to to anything an existing op can do ONLY if
they are an op.

Todo: make CHANROLE_STATUS work (the ability to apply +ov to people),
which is at the moment controlled by CHANROLE_MODE.

Jilles Tjoelker a1574df4a2 Allow kick_on_split_riding to protect channels with mlocked keys.
Do kick_on_split_riding if services sends an SJOIN
with a lower TS and a different key. This relies on
services restoring TS (changets option in atheme) and
services not immediately parting after receiving the
KICK, which is the case in recent atheme.

For invite-only channels, still only do
kick_on_split_riding in netbursts. Services is
assumed to handle this itself (atheme does).

Stephen Bennett 341f971efa Bring across disable_local_channels config option from ircd-seven 2010-12-21 20:38:04 +00:00
William Pitcock 805cfa5ab2 Use send_channel_join(). 2010-12-16 00:13:42 -06:00
William Pitcock 7a948bdaa7 Add capability parameter to sendto_common_channels_local() and sendto_common_channels_local_butone(). 2010-12-15 22:55:05 -06:00
William Pitcock cddbab51bb Send ERR_TOOMANYCHANNELS for each channel join that fails due to channel limits.
The reason why we do this is because some clients are dependent on receiving a numeric
for every channel join failure, even due to this limit where it can be assumed that
subsequent joins failed.
2010-12-14 02:24:23 -06:00
William Pitcock ff0cc1e616 Add support for linking using SSL certificate fingerprints as the link credential rather than the traditional server-password pair. 2010-12-13 23:14:00 -06:00
B.Greenham 15484f02bd Move flood_attack_channel to channel.c so it can be used outside m_message.c 2010-12-09 18:29:56 -05:00

Jilles Tjoelker 717238d2a2 Add target change for channels.
This has a separate enabling option channel::channel_target_change.

It applies to PRIVMSG, NOTICE and TOPIC by unvoiced unopped non-opers.

The same slots are used for channels and users.
