Lots of points in the sctp_cmd_interpreter function treat the sctp_cmd_t arg as a void pointer, even though they are written as various other types. Theres no need for this as doing so just leads to possible type-punning issues that could cause crashes, and if we remain type-consistent we can actually just remove the void * member of the union entirely. Change Notes: v2) * Dropped chunk that modified SCTP_NULL to create a marker pattern should anyone try to use a SCTP_NULL() assigned sctp_arg_t, Assigning to .zero provides the same effect and should be faster, per Vlad Y. v3) * Reverted part of V2, opting to use memset instead of .zero, so that the entire union is initalized thus avoiding the i164 speculative load problems previously encountered, per Dave M.. Also rewrote SCTP_[NO]FORCE so as to use common infrastructure a little more Signed-off-by: Neil Horman <nhorman@tuxdriver.com CC: Vlad Yasevich <vyasevich@gmail.com> CC: "David S.
