sctp: change to include linux/sctp.h in net/sctp/checksum.h
Currently "net/sctp/checksum.h" including "net/sctp/sctp.h" is included in quite some places in netfilter and openswitch and net/sched. It's not necessary to include "net/sctp/sctp.h" if a module does not have dependence on SCTP, "linux/sctp.h" is the right one to include.

sctp: get sctphdr by offset in sctp_compute_cksum
sctp_hdr(skb) only works when skb->transport_header is set properly.
But in Netfilter, skb->transport_header for ipv6 is not guaranteed to be right value for sctphdr. It would cause to fail to check the checksum for sctp packets.
So fix it by using offset, which is always right in all places.
v1->v2: - Fix the changelog.

sctp: force the params with right types for sctp csum apis
Now sctp_csum_xxx doesn't really match the param types of these common csum apis. As sctp_csum_xxx is defined in sctp/checksum.h, many sparse errors occur when make C=2 not only with M=net/sctp but also with other modules that include this header file.
This patch is to force them fit in csum apis with the right types.

net: sctp: fix and consolidate SCTP checksumming code
This fixes an outstanding bug found through IPVS, where SCTP packets with skb->data_len > 0 (non-linearized) and empty frag_list, but data accumulated in frags[] member, are forwarded with incorrect checksum letting SCTP initial handshake fail on some systems. Linearizing each SCTP skb in IPVS to prevent that would not be a good solution as this leads to an additional and unnecessary performance penalty on the load-balancer itself for no good reason (as we actually only want to update the checksum, and can do that in a different/better way presented here).
The actual problem is elsewhere, namely, that SCTP's checksumming in sctp_compute_cksum() does not take frags[] into account like skb_checksum() does. So while we are fixing this up, we better reuse the existing code that we have anyway in __skb_checksum() and use it for walking through the data doing checksumming. This will not only fix this issue, but also consolidates some SCTP code with core sk_buff code, bringing it closer together and removing respectively avoiding reimplementation of skb_checksum() for no good reason.
As crc32c() can use hardware implementation within the crypto layer, we leave that intact (it wraps around / falls back to e.g. slice-by-8 algorithm in __crc32c_le() otherwise); plus use the __crc32c_le_combine() combinator for crc32c blocks.
Also, we remove all other SCTP checksumming code, so that we only have to use sctp_compute_cksum() from now on; for doing that, we need to transform SCTP checkumming in output path slightly, and can leave the rest intact.

net: sctp: trivial: update bug report in header comment
With the restructuring of the lksctp.org site, we only allow bug reports through the SCTP mailing list linux-sctp@vger.kernel.org, not via SF, as SF is only used for web hosting and nothing more. While at it, also remove the obvious statement that bugs will be fixed and incooperated into the kernel.

sctp: Correct type and usage of sctp_end_cksum()
Change the type of the crc32 parameter of sctp_end_cksum() from __be32 to __u32 to reflect that fact that it is passed to cpu_to_le32().
There are five in-tree users of sctp_end_cksum(). The following four had warnings flagged by sparse which are no longer present with this change.
net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_nat_csum() net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_csum_check() net/sctp/input.c:sctp_rcv_checksum() net/sctp/output.c:sctp_packet_transmit()
The fifth user is net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt(). It has been updated to pass a __u32 instead of a __be32, the value in question was already calculated in cpu byte-order.
net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt() has also been updated to assign the return value of sctp_end_cksum() directly to a variable of type __le32, matching the type of the return value. Previously the return value was assigned to a variable of type __be32 and then that variable was finally assigned to another variable of type __le32.
Problems flagged by sparse. Compile and sparse tested only.

sctp: Fix crc32c calculations on big-endian arhes.
crc32c algorithm provides a byteswaped result. On little-endian arches, the result ends up in big-endian/network byte order. On big-endinan arches, the result ends up in little-endian order and needs to be byte swapped again. Thus calling cpu_to_le32 gives the right output.

sctp: get sctphdr by offset in sctp_compute_cksum sctp_hdr(skb) only works when skb->transport_header is set properly. But in Netfilter, skb->transport_header for ipv6 is not guaranteed to be right value for sctphdr. It would cause to fail to check the checksum for sctp packets. So fix it by using offset, which is always right in all places. v1->v2: - Fix the changelog.

sctp: force the params with right types for sctp csum apis Now sctp_csum_xxx doesn't really match the param types of these common csum apis. As sctp_csum_xxx is defined in sctp/checksum.h, many sparse errors occur when make C=2 not only with M=net/sctp but also with other modules that include this header file. This patch is to force them fit in csum apis with the right types.

net: sctp: fix and consolidate SCTP checksumming code This fixes an outstanding bug found through IPVS, where SCTP packets with skb->data_len > 0 (non-linearized) and empty frag_list, but data accumulated in frags[] member, are forwarded with incorrect checksum letting SCTP initial handshake fail on some systems. Linearizing each SCTP skb in IPVS to prevent that would not be a good solution as this leads to an additional and unnecessary performance penalty on the load-balancer itself for no good reason (as we actually only want to update the checksum, and can do that in a different/better way presented here). The actual problem is elsewhere, namely, that SCTP's checksumming in sctp_compute_cksum() does not take frags[] into account like skb_checksum() does. So while we are fixing this up, we better reuse the existing code that we have anyway in __skb_checksum() and use it for walking through the data doing checksumming. This will not only fix this issue, but also consolidates some SCTP code with core sk_buff code, bringing it closer together and removing respectively avoiding reimplementation of skb_checksum() for no good reason. As crc32c() can use hardware implementation within the crypto layer, we leave that intact (it wraps around / falls back to e.g. slice-by-8 algorithm in __crc32c_le() otherwise); plus use the __crc32c_le_combine() combinator for crc32c blocks. Also, we remove all other SCTP checksumming code, so that we only have to use sctp_compute_cksum() from now on; for doing that, we need to transform SCTP checkumming in output path slightly, and can leave the rest intact.
