Subject: ipv6: tcp: fix panic in SYN processing
From: Eric Dumazet <[email protected]>
commit c16a98ed91597b40b22b540c6517103497ef8e74 upstream.
commit 72a3effaf633bc ([NET]: Size listen hash tables using backlog
hint) added a bug allowing inet6_synq_hash() to return an out of bound
array index, because of u16 overflow.
Bug can happen if system admins set net.core.somaxconn &
net.ipv4.tcp_max_syn_backlog sysctls to values greater than 65536
