oversided server commands...

[ensiform]

since the board rolled back b4 this post was made ill post again, and its changed a bit better since then:

 

void trap_SendServerCommand( int clientNum, const char *text ) {
// rain - #433 - commands over 1022 chars will crash the
// client engine upon receipt, so ignore them
// CHRUKER: b001 - Truncating the oversize server command before writing it to the log
if( strlen( text ) > 1022 ) {
	G_LogPrintf( "%s: trap_SendServerCommand( %d, ... ) length exceeds 1022.\n", GAMEVERSION, clientNum );
	G_LogPrintf( "%s: text [%.950s]... truncated\n", GAMEVERSION, text ); return;
}
syscall( G_SEND_SERVER_COMMAND, clientNum, text );
}

Who gets the credit for the fix?

#1 and rain.

JA+ has had this fixed for a long time. I thought slider released a patch for server operators (even non-ja+)to keep this from happening...or was that another file he released.

 

I'm not sure about 2.1 or before, but I know ja+ 2.2 and ja+ 2.3 fixes this problem.

confirmed... you need something like this also at the top of G_Say:

 

	if (strlen(chatText) > MAX_SAY_TEXT) {
	G_LogPrintf( "G_Say( cl:%d ) length exceeds 150.\n", ent->client->ps.clientNum );
	return;
}

 

this will fix the chat exceeding bug where it causes server to crash. what i posted above (in the first post) the q3msgboom.cfg, etc seemed immune to it. but this stops it.

 

Update: use this in G_Say but remove the trunc line in the top post:

 

G_LogPrintf( "text [%.950s]... truncated\n", text ); return;

 

thats not needed, because it causes lag.

 

 

mmm theres still lag sometimes :S

 

so... in g_syscalls there is:

 

void trap_SendServerCommand( int clientNum, const char *text ) {
// rain - #433 - commands over 1022 chars will crash the
// client engine upon receipt, so ignore them
// CHRUKER: b001 - Truncating the oversize server command before writing it to the log
if( strlen( text ) > 1022 ) {
	G_LogPrintf( "trap_SendServerCommand( %d, ... ) length exceeds 1022.\n", clientNum );
}
syscall( G_SEND_SERVER_COMMAND, clientNum, text );
}

 

then in G_Say:

	if (strlen(chatText) > MAX_SAY_TEXT) {
	G_LogPrintf( "G_Say( cl:%d ) length exceeds 150.\n", ent->client->ps.clientNum );
	return;
}

 

 

but the console basically shows 3 lines of the g_syscall warning.

 

  2:13 G_Say( cl:2 ) length exceeds 150.
 2:13 trap_SendServerCommand( 2, ... ) length exceeds 1022.
 2:13 trap_SendServerCommand( 2, ... ) length exceeds 1022.
 2:13 trap_SendServerCommand( 2, ... ) length exceeds 1022.

Is that "the" fix...or is that the fix that you said still had problems? I know you and Slider got together to talk about getting the permanent fix. It this it? or is this the still buggy one?

[ensiform]

pretty much yes you just must stop the execution of G_Say or G_SayTo i believe in order for the chat exploit to stop working.
