From: Gerrit Renker <gerrit@xxxxxxxxxxxxxx> Date: Mon, 8 Feb 2010 07:20:28 +0100 > This fixes a problem in the DCCP getsockopt() API: currently there is no way > for a user to a priori know the number of built-in CCIDs, other than trying > DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until > EINVAL is no longer returned. > > This patch truncates the array to the user-provided length. No copy is made > when the length is <= 0. > > Due to the length restriction in do_dccp_getsockopt() to sizeof(int), the > minimum array length remains 4, which is a reasonable default (only 3 > CCIDs, CCID-2..4, are currently defined). > > Signed-off-by: Gerrit Renker <gerrit@xxxxxxxxxxxxxx> Applied to net-next-2.6, thanks Gerrit. -- To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
