XFRM: copy_to_user_kmaddress() reports local address twice
While adding support for MIGRATE/KMADDRESS in strongSwan (as specified
in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen
noticed that XFRMA_KMADDRESS attribute passed to userland contains the
local address twice (remote provides local address instead of remote
one).
This bug in copy_to_user_kmaddress() affects only key managers that use
native XFRM interface (key managers that use PF_KEY are not affected).
For the record, the bug was in the initial changeset I posted which
added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d
'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').
