sctp: validate from_addr_param return ...
[ Upstream commit 0c5dc070ff3d6246d22ddd931f23a6266249e3db ]
Ilja reported that, simply putting it, nothing was validating that
from_addr_param functions were operating on initialized memory. That is,
the parameter itself was being validated by sctp_walk_params, but it
doesn't check for types and their specific sizes and it could be a 0-length
one, causing from_addr_param to potentially work over the next parameter or
even uninitialized memory.
The fix here is to, in all calls to from_addr_param, check if enough space
is there for the wanted IP address type.
