Hello,
I would like to apply this patch on 5 and 6 branches. I'll create
tickets before applying it.
Best regards
Christian

The racoon session code copies an fd_set from one variable into another
prior to calling select. That works well for simple structures.
In libbsd we have to allocate fd_sets instead of using fixed structures
to avoid a problem with file numbers bigger than FD_SETSIZE. The simple
assignment didn't work in that case.
This patch makes sure that a memcpy is used instead.
