init_socketpath() was building a sprintf() format string intended to be used by /DETACH to create the socket
file name. This included the actual socket path, plus a %d for the port, plus the sanitised tty name and
hostname.
Only one caller needed all this though - the /DETACH command - and the other callers (in scr-bx.c) just
wanted to truncate it to the actual socket path. The format string also wasn't safe - if the home directory
path, hostname or ttyname contained % characters these werent being escaped.
It simplifies things to have init_socketpath() just return the actual socket path, after creating the 'screens'
directory if necessary. This lets the code in scr-bx.c use it as-is, and removes the need for the global
socket_path variable. The code to include the sanitised tty name and hostname in the socket file name can
be moved to the create_ipc_socket() function.
There's no need to check access() for the socket path before trying to create it - just call mkdir() regardless,
since it will fail if the path already exists, which is fine.
This commit also adds error handling to the create_ipc_socket() function for the case where creation of the
socket file fails, and switches the chmod() and chown() for the opened file to the more appropriate fchmod()
and fchown().
The function provided (either by #define to the module table or directly in the case of scr-bx.c)
is called my_ltoa(), and the #define in irc_std.h aliases this to ltoa().
remove_channel() is only called in direct response to a message from a server,
so it always acts on from_server - remove the unnecessary server argument.
The channel argument is always non-NULL - remove the dead code that removed all
channels if a NULL channel was passed.
The declaration of dcc_dllcommands in modules.c was wrong - add it to dcc.h so it's checked against the definition in dcc.c
and include it from there.
The DCC_dllcommands structure isn't structured like a "List2" so remove_module() doesn't work - use remove_from_list_ext().
Using sequential constants for *_FLOOD constants means that we can use a simple lookup table to convert them
into text for display and IGNORE_* constants.
This adds a FLOOD_FLAG() macro to convert a _FLOOD constant to the appropriate flag. For now this just
casts the argument to unsigned int.
Rename Flooding.type to Flooding.flags and change it to unsigned int, to reflect that it's a bitfield of
flags for multiple flooding types.
All callers of flood_prot() were supplying { get_flood_types(flood_type), flood_type } as the second and third arguments,
except one that supplied { get_flood_types(CTCP_FLOOD), CTCP_ACTION_FLOOD }.
Hardwiring this logic in to flood_prot() lets us remove the 'type' argument without changing the behaviour.
The static 'pos' variable in check_flooding() would not stay in sync with the number of entries in
flood_list after clean_flood_list() was called. This meant that check_flooding() would always end up
removing all previous entries if it tried to add a new one.
Fix this by removing the tracking of number of flood_list entries, and just removing stale ones (older
than /SET FLOOD_RATE).
Checking before truncation means you can sneak a privileged port past the check.
This change also collects the various broken-out parts of a CTCP DCC offer into a struct so that
it's easier to pass them all around together.
glob_commands() would run off the end of the irc_command array if given a match that matched
the last command. It also leaked memory because it used m_s3cat() to construct the string,
then passed that to m_strdup().
This fixes these problems by reworking glob_commands(), and at the same time removes the use
of alloca() and wild_match() by using strncmp() instead to match the start of a string. Move
glob_commands() to alias.c and make it static since it's only used for aliasctl().
Change the 'name' argument of find_command() and find_dll_command() to const char * at the same
time, so that glob_commands()'s prefix argument can be const char * too.
The 'channels' argument was unnecessary because the channel list passed to it would
always be from get_server_channels(server) anyway.
Changing the message argument from a protocol message format string to a plain payload
string for PRIVMSG means printf-escaping of the argument is avoided in the caller.
This simplifies the callers and means we can remove the last use of quote_it().
This change also switches set_server_away() to use send_msg_to_channels() instead of
open-coding the equivalent, which simplifies that function a lot.
We are changing the signature of a function exported to modules here; however none
of the in-tree modules use this function so it should be OK.
Identifiers beginning with two underscores or one underscore and a capital
letter are reserved in all contexts, including macros.
The __N macro in irc_std.h is in this space, and was conflicting with a macro
definition in gcc 5.4.0's xmmintrin.h under cygwin, making the build fail.

This FSET has existed for a long while but has been unused for some time,
since before the userlist was reworked to use flags instead of levels. This
means that the default value for the FSET also has to be updated.
This switches from somewhat gory string parsing based on strncmp() and next_arg() to a simpler alternative
based on sscanf(). I think these are much easier to understand now, and shouldn't have any subtle bugs
lurking like the old code.
This also removes support for some obsolete messages that don't seem to be in any modern ircds:
"Identd reponse differs"; bot messages like "Rejecting vlad/joh/com bot:" except for "is a possible spambot"
which is still in use; and the "High-traffic mode" messages.
serversay() calls add_last_type(), so there's no need for the callers to do so
as well.
Remove the first argument to serversay() because it was always called with 1
anyway.
Remove the extra space in the default /fset SERVER_NOTICE, and similarly
the extra space in the HUMBLE /set SERVER_PROMPT.
The code in the client always _intended_ to add a space between SERVER_PROMPT
and SERVER_NOTICE_FSET but a bug in 75p3 and below meant it that it didn't.
This bug was fixed in 1.0b but the formats were never updated.
Also remove replace the embedded ANSI in the default SERVER_PROMPT with
% color code.
We don't know the server's proper name until registration, so the test against
that isn't reliable. We shouldn't be able to receive messages from anyone else
until we're registered, so this should be safe.
This requires changing serversay() to accept the from name instead of the
from_server. While we're there, replace the use of alloca() with simpler
logic based on m_sprintf().
This hook and format are used for NOTICEs where the destination isn't
a channel and isn't yourself - eg. global targets like $$*.org. This was
already the case for PRIVMSGs (using the MSG_GROUP hook and format).
Previously these were being routed like a normal NOTICE, and those don't
display the target, so it looked exactly like a private NOTICE to you.
This will also catch server notices sent before you're registered.
Functions display_msg() and check_sync() are only used in numbers.c, so they
can be static.
Remove inclusions of <numbers.h> from .c files that don't need it.
Some systems need <sys/sockio.h> for the SIOCGIFCONF ioctl - this switches
to using a proper configure check for that header rather than just assuming
it'll be there if we can't find SIOCGIFCONF. Should be more robust.
Only include <netinet/in.h> and <sys/socket.h> if the system supplies them.
This is necessary to try and get the mingw32 build working again.
No need to include <sys/types.h> and <netinet/in.h> from cdns.c - these are
already included by <irc.h>.
There's several different types of DCC offers, all of which need slightly
different handling. Previously they were all handled by the monster function
register_dcc_type() - this breaks them out into seperate functions for handling
SEND, RESEND, CHAT and BOT offers, moves common code into static helper
functions and renames the entry point from ctcp.c to handle_dcc_offer().
This will allow adding a way for modules to register DCC offer types that
they're interested in.
This also moves rename_file() from misc.c into dcc.c, where its only user is.
Mark DCC connections that we have requested RESUME on, so that we know
whether or not to act on a DCC ACCEPT that is received.
Also fixes up a slightly wrong message in /DCC RESUME.
DCC_CNCT_PEND was only ever set, not tested, so it was pointless.
There's no point only defining DCC_SSL when HAVE_SSL is defined: we can't
re-use that flag bit anyway, so might as well just define it always.
Also fixes a "flags && DCC_WAIT" that should have been "flags & DCC_WAIT".
This has no practical effect though I believe, since as far as I can tell
DCC_WAIT would always be set at that point anyway.
