RFC 2533 refers to 'A Syntax for Describing Media Feature Sets',

071966e874 libc sctp: fix sctp_getladdrs() when reporting no addresses
Section 9.5 of RFC 6458 (SCTP Socket API) requires that
sctp_getladdrs() returns 0 in case the socket is unbound. This
is the cause of reporting 0 addresses. So don't indicate an

6aae3517ed Retire synchronous PPP kernel driver sppp(4).
The last two drivers that required sppp are cp(4) and ce(4).

These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.

Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially.  Later they have dropped
support for Linux drivers to.  As of mid-2020 they don't even
have a developer to maintain their Windows driver.  However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.

These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP.  Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.

Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part.  Further maintenance of these
drivers in the tree shouldn't be a big deal.

While doing that, remove some cruft and enable cp(4) compilation
on amd64.  The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

5245bf7b92 lib/libc/net/nsdispatch.c: Fix missing unlock and add locking annotations
The error cases (goto fin) of _nsdispatch were missing the unlock.

This change also drops the checks for __isthreaded since the pthread stubs
are already no-ops if threads are not being used. Dropping those conditionals
allows clang's thread safety analysis to deal with the file and also makes
the code a bit more readable. While touching the file also add a few more
assertions in debug mode that the right locks are held.

6b462d2762 Increase YPMAXRECORD to 16M to be compatible with Linux.
Since YP protocol definition uses the constant to declare
variable-size opaque byte strings, the change should be binary
compatible with existing installations which do not expose keys or
values larger than 1024 bytes.

All uses of local variables with YPMAXRECORD sizes were removed to
avoid insane stack use.  On the other hand, variables with static
lifetime should be fine and only result in increased VA use.

Glibc made same change, increasing the allowed length for keys and
values in YP to 16M, in 2013.

20d96999a4 Make getnameinfo(3) salen requirement less strict and

getnameinfo(3) returned EAI_FAIL when salen was not equal to
the length corresponding to the value specified by sa->sa_family.
However, POSIX or RFC 3493 does not require it and RFC 4038
Sec.6.2.3 shows an example passing sizeof(struct sockaddr_storage)
to salen.

This change makes the requirement less strict by accepting
salen up to sizeof(struct sockaddr_storage).  It also includes
two more changes: one is to fix return values because both SUSv4
and RFC 3493 require EAI_FAMILY when the address length is invalid,
another is to fix sa_len dependency in PF_LOCAL.
