* Retire synchronous PPP kernel driver sppp(4).Gleb Smirnoff2021-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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. Reviewed By: markj Differential Revision: https://reviews.freebsd.org/D29372

* Increase YPMAXRECORD to 16M to be compatible with Linux.Konstantin Belousov2019-08-123-10/+19
| | | | | | | | | | | | | | | | | | | | | | | 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.
