[SCTP]: Fix kernel panic while received AUTH chunk while enabled auth
If STCP is started while /proc/sys/net/sctp/auth_enable is set 0 and association is established between endpoints. Then if /proc/sys/net/sctp/auth_enable is set 1, a received AUTH chunk will cause kernel panic. Test as following: step 1: echo 0> /proc/sys/net/sctp/auth_enable step 2: SCTP client SCTP server INIT ---------> <--------- INIT-ACK COOKIE-ECHO ---------> <--------- COOKIE-ACK step 3: echo 1> /proc/sys/net/sctp/auth_enable step 4: SCTP client SCTP server AUTH -----------> Kernel Panic This patch fix this probleam to treat AUTH chunk as unknow chunk if peer has initialized with no auth capable. > Sorry for the delay.
