717f809762 Don't treat +r specially when displaying supported channel modes.
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.

894325fe41 Force client_flood_burst_rate and client_flood_burst_rate to at least rfc1459 values (5). 2011-10-04 22:16:01 +02:00

5a72f20c2c Limit sent_parsed to the highest possible value in the current config.
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.

a75bf40dad Fix weirdness with client_flood_burst_rate and client_flood_burst_max.
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.

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.

f890420014 Ensure all signals keep working after a SIGINT restart.
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

slow weekend.

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

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.

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.

2fb0796158 hunt_server: Disallow wildcarded nicknames.
Any hunted parameter with wildcards is now assumed
to be a server, never a user.

Reasons:
* fewer match() calls
* do not disclose existing nicknames
* more intuitive behaviour for CONNECT

m_trace has a copy of some hunt_server logic in it
(for the RPL_TRACELINK reply), so adjust that too.

fa0e215255 Tweak previous commit to avoid problems with OMODE.
Do not allow a user to op themselves if they are
already opped, as "already opped" could be because
of OMODE's hack which will be unconditionally
reverted after the mode change.

Also, this matches old behaviour for users not
being able to generate mode changes redundantly
opping themselves.

Note that this change should only be taken advantage
of if all servers run patched code. Otherwise, mode
changes will be silently dropped and a desync
results.

19716b9fd6 New custom channel mode API allowing reloading such modules.
Additionally, attempting to use too many modes or two times
the same letter is now detected and prevented.

Modules now request that a channel mode be added/orphaned,
instead of ugly manipulation from which that request had
to be guessed.

Slight changes are needed to modules that provide channel modes.
From the old API, one important function has been made static,
the other important function has been renamed, so loading old
modules should fail safely.
