2017-02-07sctp: drop __packed from almost all SCTP structuresMarcelo Ricardo Leitner1-1/+1
__packed is considered harmful as it potentially generates code that doesn't perform well and its usage should be avoided as much as possible. This patch drops __packed from all SCTP structures except one, which is sctp_signed_cookie. In there it's required, as per changelog on commit 9834a2bb4970 ("[SCTP]: Fix sctp_cookie alignment in the packet."). After this patch, no alignment changes neither in x86 or x86_64 and no exceptions were noticed during testing on both archs. Code size for SCTP module also didn't change with this patch.

2017-02-07sctp: add dst_pending_confirm flagJulian Anastasov1-0/+4
Add new transport flag to allow sockets to confirm neighbour. When same struct dst_entry can be used for many different neighbours we can not use it for pending confirmations. The flag is propagated from transport to every packet. It is reset when cached dst is reset. Reported-by: YueHaibing <yuehaibing@huawei.com> Fixes: 5110effee8fd ("net: Do delayed neigh confirmation.") Fixes: f2bb4bedf35d ("ipv4: Cache output routes in fib_info nexthops.")
