1870e06ad3 autotools: fix typo relating to ban db 2014-01-31 11:03:54 -05:00

7f3382fe98 Remove duplicate default-value code.
Default values for default_floodcount and default_ident_timeout are set
in s_conf.c. Remove code that checks for missing values in ircd.c.
Additionally, reset default_ident_timeout to 5 if an invalid value (i.e.
0) is provided.

364e59f82a whowas: Use the normal rules for IP visibility.
Add the flags (auth{} spoof, dynamic spoof) to struct Whowas and add a
show_ip_whowas().

Normal users now see IPs of unspoofed users, and remote opers can see IPs
behind dynamic spoofs. Also, general::hide_spoof_ips is now applied when
the IP is shown, not when the client exits.

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.

3c93d380e0 Add support for multiple forms of blacklist queries using matches.
It supports both literal and last octet matches from the dnsbl.
If matches is not present, the old behaviour is used.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

c598ff7b04 Fold client_flood_burst_rate check into MAX_FLOOD_BURST.
The original definition of floodgrace was MAX_FLOOD_BURST lines per second.
