Al Viro 09ef7fecea [SCTP]: Beginning of conversion to net-endian for embedded sctp_addr.
Part 1: rename sctp_chunk->source, sctp_sockaddr_entry->a,
sctp_transport->ipaddr and sctp_transport->saddr (to ..._h)

The next patch will reintroduce these fields and keep them as
net-endian mirrors of the original (renamed) ones.  Split in
two patches to make sure that we hadn't forgotten any instanes.

Later in the series we'll eliminate uses of host-endian variants
(basically switching users to net-endian counterparts as we
progress through that mess).  Then host-endian ones will die.

Other embedded host-endian sctp_addr will be easier to switch
directly, so we leave them alone for now.

CCID 3 states to use enums, in that many conditions are now simplified

In a few instances, this also allowed to simplify pre-conditions; where
care has been taken to retain logical equivalence.

[DCCP]: Introduce a consistent BUG/WARN message scheme

This refines the existing set of DCCP messages so that
 * BUG(), BUG_ON(), WARN_ON() have meaningful DCCP-specific counterparts
 * DCCP_CRIT (for severe warnings) is not rate-limited
 * DCCP_WARN() is introduced as rate-limited wrapper

Using these allows a faster and cleaner transition to their original
counterparts once the code has matured into a full DCCP implementation.

reasonable to consider the NetLabel Netlink interface as a form of syscall so

The CIPSOv4 translated tag #1 mapping does not always return the correct error
code if the desired mapping does not exist; instead of returning -EPERM it
returns -ENOSPC indicating that the buffer is not large enough to hold the

should allow the LSM to do a quick comparison to determine if the structure
