William Pitcock 3dae60ef47 cache: use rb_strdup() instead of a static buffer for cache lines.
BUFSIZE limitation is retained as there is no need to remove it, as all lines must be smaller than it
due to RFC1459 message requirements.

Jilles Tjoelker 22cae20f02 server: Make sure CAP_CAP and CAP_TS6 are non-zero.
A zero CAP_CAP caused duplicate CAPAB to go undetected, allowing a
mismatch between what is sent out via ENCAP GCAP and what applies locally.

A zero CAP_TS6 allowed server connections without SID (with a valid
connect block).

William Pitcock 1cf9ef50cd numeric: add 744 (ERR_TOPICLOCK) to list so we don't step on inspircd 2012-10-13 17:50:12 +00:00
Keith Buck 5bd79c2c56 res.c: Try other servers if errors or corrupt replies are encountered.
Currently, the resolver treats SERVFAIL, NOTIMP, and REFUSED queries the
same as NXDOMAIN, but this really should not be the case. Instead, if
the DNS server errors on our request or provides an invalid request, try
another server.

Also, count DNS server errors in addition to timeouts and avoid these
undesirable servers.

Keith Buck 7d60375446 Add new conf_read_start and conf_read_end hooks. 2012-05-21 20:22:07 +00:00
Keith Buck 62cf5b4036 Call the privmsg_channel hook for part messages too. 2012-04-07 03:03:07 +00:00
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 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.

Jilles Tjoelker 57b1cd5f6b strip_colour: Prefer IsDigit to isdigit.
Unlike isdigit, IsDigit can safely be applied to 'char's.
Arguments to isdigit needs a character cast to 'unsigned char' or EOF.

Jilles Tjoelker aba43ba823 When stripping colour/control codes, also strip \004.
Some clients such as irssi interpret \004 as colour or other markup.

Nathan Phillip Brink 9f9b7042fb Run autoconf and autoheader. 2012-03-01 03:49:35 +00:00
Nathan Phillip Brink c74836dc4a Add explicit support for being installed into a system triggered with --enable-fhs-paths.
Add two mechanism for avoiding name-collisions in a system-wide
installation of charybdis. The ssld and bandb daemons, intended to be
directly used by ircd and not the user, install into libexec when
--enable-fhs-paths is set. For binaries which are meant to be in PATH
(bindir), such as ircd and viconf, there is now an option
--with-program-prefix=progprefix inspired by automake. If the user
specifies --with-program-prefix=charybdis, the ircd binary is named
charybdisircd when installed.

Add support for saving the pidfile to a rundir and storing the ban
database in localstatedir instead of in sysconfdir. This is, again,
conditional on --enable-fhs-paths.

Fix(?) genssl.sh to always write created SSL key/certificate/dh
parameters to the sysconfdir specified during ./configure. The
previous behavior was to assume that the user ran genssl.sh after
ensuring that his current working directory was either sysconfdir or a
sibling directory of sysconfdir.

Jilles Tjoelker f8e43a0b8f Remove dummies, given that ratelimit already broke the ABI once.
As with ratelimit, ircd/modules before and after this commit
are incompatible, but not detected as such.

William Pitcock 63a0ed0604 numeric: reserve RPL_SASLMECHS (908) 2012-02-21 09:15:15 -06:00
Jilles Tjoelker d42e6915cf Pace aways.
This becomes important because of away-notify sending aways to common
channels much like nick changes (which are also paced).

Marking as unaway is not limited (but obviously only does something if the
user was away before). To allow users to fix typos in away messages, two
aways are allowed in sequence if away has not been used recently.

William Pitcock 346fba9252 Migrate capability negotiation code to new dynamic capability management API.
This needs a lot of testing, obviously.

William Pitcock ec3a9055f2 capability: add capability_index_mask() which calculates old CAP_MASK 2012-02-04 00:39:53 -06:00
William Pitcock 5e773521a9 capability: add capability_index_list() to build a list of capabilities given an index and mask 2012-02-04 00:36:42 -06:00
William Pitcock 64b56afd8c Add a new dynamic capability manager.
Specifically, what this capability manager does, is map keywords to
calculated bitmasks.  These bitmasks are allocated at runtime, so that
the any managed capability index can be manipulated by modules.

Modules should call capability_orphan() when orphaning capabilities.  This
makes it so that bitmasks aren't reallocated, except for cases where the
capability is the same.

Jilles Tjoelker 524a5b3ac7 Add code to get IPv4 addresses from 6to4 and Teredo IPv6 addresses.
It is not used yet.

Jilles Tjoelker be0365e152 Add an error message if a ban mask is invalid.
This is given if the ban mask is too long, it is an invalid extban or the
forward channel is invalid and no other message has been given about that.

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 d74fa5b502 Prefer PATH_MAX to non-standard MAXPATHLEN. 2011-10-28 16:45:18 +02:00
Jilles Tjoelker d182b85454 Minor cleanup to command throttling code:
* Deduce allow_read from the client's state (IsFloodDone) rather than
   storing it in LocalUser.
 * Fix the documentation (in oper /info), however strange
   client_flood_burst_rate and client_flood_burst_max may seem, that is
   how they currently work.

Jilles Tjoelker f9dda63969 Disable LocalUser.actually_read (write-only field). 2011-10-04 00:25:22 +02:00
Jilles Tjoelker c598ff7b04 Fold client_flood_burst_rate check into MAX_FLOOD_BURST.
The original definition of floodgrace was MAX_FLOOD_BURST lines per second.
A second check for another number of lines per second makes no sense.

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
William Pitcock f3bfe2c271 chanroles: instead of checking for chanop + CHANROLE_UNSET combination, grant a default set of flags.
this allows ops with zero effective privilege.
2011-07-06 15:12:46 -05:00
William Pitcock ae79dab6ae chanroles: grant initial set of flags to people added to a channel with CHFL_CHANOP.
this allows us to, later on, add a hook that will enable us to disable channel ops entirely
without causing permissions revocation.
2011-07-06 15:00:32 -05:00
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.
