2017-07-14sctp: fix an array overflow when all ext chunks are setXin Long1-2/+2
Marcelo noticed an array overflow caused by commit c28445c3cb07 ("sctp: add reconf_enable in asoc ep and netns"), in which sctp would add SCTP_CID_RECONF into extensions when reconf_enable is set in sctp_make_init and sctp_make_init_ack. Then now when all ext chunks are set, 4 ext chunk ids can be put into extensions array while extensions array size is 3. It would cause a kernel panic because of this overflow. This patch is to fix it by defining extensions array size is 4 in both sctp_make_init and sctp_make_init_ack.

2017-07-01sctp: Add peeloff-flags socket optionNeil Horman1-15/+72
Based on a request raised on the sctp devel list, there is a need to augment the sctp_peeloff operation while specifying the O_CLOEXEC and O_NONBLOCK flags (simmilar to the socket syscall). Since modifying the SCTP_SOCKOPT_PEELOFF socket option would break user space ABI for existing programs, this patch creates a new socket option SCTP_SOCKOPT_PEELOFF_FLAGS, which accepts a third flags parameter to allow atomic assignment of the socket descriptor flags.
