udplite: Protection against coverage value wrap-around
[ Upstream commit 47112e25da41d9059626033986dc3353e101f815 ] This patch clamps the cscov setsockopt values to a maximum of 0xFFFF. Setsockopt values greater than 0xffff can cause an unwanted wrap-around. Further, IPv6 jumbograms are not supported (RFC 3838, 3.5), so that values greater than 0xffff are not even useful. Further changes: fixed a typo in the documentation. [ Add USHORT_MAX from upstream to linux/kernel.h -DaveM ] Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
