After a change for dynamic server capabilities, the code to send out mode
changes was changed to use the capabilities belonging to the last mode
being sent out. This does not make sense; therefore, just use no
capabilities and remove supporting infrastructure.
The code to send each channel mode only to servers supporting it was
broken a while ago and was not very useful anyway. Therefore, require
all connecting servers to support all standard channel modes.
Fixes compilation warning about losing const qualifier in assignment to
non-const variable
(cherry picked from commit 6d9c3f50944e1da3bf3a1be6454f85d6d6f7ab37)
This change prevents the log file paths from being leaked when
rehashing. Additionally, fname_killlog was added to two places where it
was previously forgotten.
This change prevents conf strings from being leaked when resetting the
conf to default prior to a rehash. Additionally, some default strings
are now rb_strdup'd into the ConfigFileEntry structure after loading the
conf so that they aren't allocated and then immediately freed by the
conf loading process.
The MASK_IP case in log_client_name() was broken (because of a missing
break, it behaved as HIDE_IP). However, log_client_name() with MASK_IP
does not make sense anyway and is not used.
If a listening port cannot be opened, send error messages to opers with
snomask +s and ircd.log, instead of snomask +d and the ioerror log, which
both are usually disabled.
Also, restore information about what listener is having problems. This
was lost when report_error() was replaced.
Charybdis currently leaks about 45-50k per configuration parse,
including every rehash. This change plugs these leaks by properly
iterating through all conf_parm_t structures to seek all strings that
should be freed and also by freeing the conf_parm_t structures
themselves.
These leaks have been present since the original rewrite of the
configuration parsing system in ircd-ratbox r11953.
Additionally, this change also cleans up and documents the parsing code
a bit.
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.
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.
For one, [draft-brocklesby-irc-isupport-02][1] already defines "ascii" as the
default value. According to section 2 ("Except as
explicitly stated in its definition, a parameter should not be sent
unless it changes this default value, or the default value is vague,
badly defined, or differs between IRC server implementations"), there is
no point in sending it.
For another, [version 03 of the same draft][2] removes CHARSET ("It was
found to be unworkable; a correct specification could not be devised to
represent its meaning across implementations."), and the token is not
present at all in [draft-hardy-irc-isupport-00][3].

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.
When the configuration file is unreadable or not existing, charybdis will now report the POSIX error message from the failed call. This is a compromise between the behavior in f951460ae9 and f6f049070e.
Previously it was in src/ircd.c, but accroding to jilles, this is a better place for the notification.
This changes a patch made in adef4da10c and amended in 65d921173c and f6f049070e.
They will be treated as hostmasks only. In the case of dlines they will
be rejected as invalid.
hostmask.c entries such as dlines, klines and auth blocks can only be
added by opers or via ircd.conf.
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).
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.
Check mlock at the same point where chanops are checked (except for
querying a +e/+I list) and abstract this check into a function.
In particular, /mode #channel f is now again allowed if +f is mlocked.
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.
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.
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.
This makes accounting of number of bits allocated easier. Specifically, the amount of allocated
bits is computed by doing (index->highest_bit - 1) in code.
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.
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.
This used to be only advertised if a service was linked, which made
sense in ratbox when +r was only settable if services were available.
Now, however, +r is always available and so should always be advertised.
After a configuration change (or deoper with no_oper_flood) sent_parsed
might be way higher than allow_read, so that the user would have to wait
a long time before the server responds. Avoid this.
They are now in messages, even if client_flood_message_time is not 1.
If client_flood_message_time is not 1 (by default it is), this needs a
configuration change to maintain the same behaviour.
* 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.
After setting up signal handlers, unmask the signals we care about
(installed handlers for).
When handling SIGINT, the kernel adds SIGHUP and SIGINT to the signal
mask (as requested in sigaction()); if execve() is called from the
signal handler, this change is persistent.
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!
