What I found was the following two issues. Although these two are
technically quite trivial, what I was fearing was a lack of report to
KAME, since this may mean a lack of KAME-SCTP users.
- inconsistency between KAME specific kernel code and SCTP leads
to an kernel compilation error.
Of course, it's a technically trivial bug and our own bug.
- including SCTP in getaddrinfo() causes 'configure' script error
in many ports applications.
This is also a trivial problem, and maybe specific to KAME SCTP.
And some of such ports are already fixed when I encounter this
problem.
(e.g. http://www.freebsd.org/cgi/cvsweb.cgi/ports/lang/python/files/patch-configure.diff?r1=1.7&r2=1.8)
But now I understand that lack of report does not mean a lack of
testing users (since SCTP-lovers seems communicating directly to your
team). So I can be much more optimistic now, and don't object to
merging it into -current, since such trivial bugs can be fixed easily
in -current. (I myself haven't tested SCTP very well, so I cannot
comment on its stability itself. But at least, SCTP does not seem to
affect the behavior of other protocols)
Thanks and sorry if you feel my previous comments were insulting...
