Bug: Name authorization listings for changed names are not being properly reallocated.
Discovered in: AFKMud 1.64
Danger: Medium - Memory leak
Found by: Samson
Fixed by: Samson

---

new_auth.c, find the do_name function.

Locate:
  STRFREE( ch->name );
  ch->name = STRALLOC( argument );
  STRFREE( ch->pcdata->filename );
  ch->pcdata->filename = STRALLOC( argument );
  send_to_char( "Your name has been changed and is being submitted for approval.\n\r", ch ); 
  auth_name->name = STRALLOC( argument );
  auth_name->state = AUTH_ONLINE;
  STRFREE( auth_name->change_by );        
  save_auth_list();
  return;


Replace that segment with this:

   STRFREE( ch->name );
   ch->name = STRALLOC( argument );
   STRFREE( ch->pcdata->filename );
   ch->pcdata->filename = STRALLOC( argument );
   send_to_char( "Your name has been changed and is being submitted for approval.\n\r", ch );
   STRFREE( auth_name->name );
   auth_name->name = STRALLOC( argument );
   auth_name->state = AUTH_ONLINE;
   STRFREE( auth_name->change_by );
   save_auth_list(  );
   return;


When a player changes names using the do_name code, the auth list is supposed to get updated to reflect the new name being submitted for authorization. However, the old name that was previously in the list is never freed beforehand and results in a memory leak. Compounded over enough time this will lead to degraded performance of the MUD.

This particular issue also affects the name authorization snippet code which has been corrected.
