973e0a7e9c Refresh master server address cache every 24 hours
Resolve master server addresses every 24 hours instead of keeping
result forever. Don't clear sv_master[1-5] cvar if the address fails
to resolve; it might work later.

615b73288f Use Opus for VoIP
Server/client VoIP protocol is handled by adding new cvars
cl_voipProtocol and sv_voipProtocol, sv_voip and cl_voip
are used to auto set/clear them. All users need to touch
are cl/sv_voip as 0 or 1 just like before.

Old Speex VoIP packets in demos are skipped.
New VoIP packets are skipped in demos if sv_voipProtocol
doesn't match cl_voipProtocol.

Notable difference between usage of speex and opus codecs,
when using Speex client would be sent 80ms at a time.
Using Opus, 60ms is sent at a time. This was changed because
the Opus codec supports encoding up to 60ms at a time.
(Simpler to send only one codec frame in a packet.)

dd82b9d1a8 Fix case where interval overflows (thanks jackeri)
[17:58] <Jacker> hey, you might be interested in checking out this
4da5a397b5 (diff-acaedc9d8b492f9af8966ae68597392cR615)
[17:58] <Jacker> its related to the ddos protection code you wrote
[17:59] <Jacker> in continuation to:
ab9b08e584
[17:59] <Jacker> in a case if the client has in the past connected to
the server days/weeks earlier and time wraps the client wont be able to
connect
[18:00] <Jacker> since in that case if the bucket of that clients ip
still exists it wont get checked correctly

ba385fa43c - Switch master server protocol to dpmaster for better game separation. Based partly on patch by Zack Middleton
- Get rid of ugly cvars sv_heartbeat and cl_gamename and replace with single com_gamename
- Remove sv_flatline. Flatlines are ignored by dpmaster and are considered to be insecure because flatlines can be udp-spoofed.

ac30d86db0 - Improve snapshot rate and data rate control
- Make server send packet fragments and queued packets when server is idle
- Voip protocol detection is tied to com_protocol making past-end-of-message reading unncessary
- Use Hunk_AllocateTempMemory() for buffering VOIP packets and fix buffering scheme that ryan hates so much
- Disable packet scrambling for new protocol as it is useless now
- Get rid of the old packet scrambling functions predating latest point release
- Use Hunk_AllocateTempMemory() for netchan packet queue to fix memory leak when client gets disconnected with packets in the queue
- Use Hunk_AllocateTempMemory() for download blocks to fix memory leak when client gets disconnected with download blocks in the queue
- Fix SV_RateMsec to account for udp/udp6 packet lengths

50ca55702f - Introduce new NET_CompareBaseAdrMask for easy comparison of ip address ranges
- Overhaul of the new banning functions:
  * basic check for redundant bans/exceptions
  * introduction of sv_banFile to make it possible to configure the file where to read bans and exceptions from
  * bans can now be deleted by giving address ranges, too.

5d63a38ad9 Basic IPv6 support. Some inspiration from the patches by Lubos Dolezel and JF Tremblay at https://bugzilla.icculus.org/show_bug.cgi?id=2355. 2008-04-04 23:22:22 +00:00

e46fe24426 * rewrite of the win32 dedicated console:
1) NET_Sleep() no longer watches for input, Sys_Sleep() added for waiting
     on input.
  2) Added "CtrlHandler" for trapping Ctrl-C and other quit methods not
     handled by signals on windows
  3) Added history support
  4) Added tab completion
  5) Removed automatic cursor/scroll adjustment (too problematic)
  6) Enable mousewheel scrolling
  7) Stop using the InputBuffer for editing

  This seems to work pretty well now, but I jumped the gun on a previous
  commit message by saying you can scroll now without locking up your server.
  That was only true up until the point that a server tried to print to
  the console, at that point it will hang until you release the scroll bar :(
  It may be possible to get around this by using a seperate thread for
  console output, but that's a whole new can of worms.

integer overflow in Com_Milliseconds() (R1CH)

Tony J. White =
189e8b33f3 * (bug 2784) help to prevent reliable command overflow in cases when a slow
client is loading the map on a busy server. Specifically, hold back all
  configstring update commands while the client is CS_PRIMED.  Once the
  client goes from CS_PRIMED to CS_ACTIVE, send the cleint commands for
  updating each of the configstring indexes which were updated while the 
  client was CS_PRIMED.
