Eric Dumazet says: ==================== tcp: make sack processing more robust Jonathan Looney brought to our attention multiple problems in TCP stack at the sender side. SACK processing can be abused by malicious peers to either cause overflows, or increase of memory usage. First two patches fix the immediate problems. Since the malicious peers abuse senders by advertizing a very small MSS in their SYN or SYNACK packet, the last two patches add a new sysctl so that admins can chose a higher limit for MSS clamping. ==================== Signed-off-by: David S.
