2012-01-28Remove a horrible sppp(4)-specific "fast queue" used for tcp ports 21 23 513.Stuart Henderson
You should use the proper queues via pf instead. ok phessler@ henning@
2012-01-19Teach pppoe(4) about RFC 4638. This allows negotiating increased MTU withStuart Henderson
compatible equipment provided that the physical interface and other layer 2 devices involved support and are configured to use jumbo frames. Manpage to follow; typical use is to request 1500 MTU for pppoe, this requires 1508+ MTU on the physical interface, e.g. "ifconfig em0 mtu 1508; ifconfig pppoe0 mtu 1500". Known to be usable in the UK with some ISPs (e.g. aaisp) using BT FTTC backhaul. From Matt Dainty, originally based on support in NetBSD, changed to decouple pppoe from physical interface MTU. Tested with UK FTTC by Matt, no regressions on my standard UK ADSL setup or yasuoka@'s setup (in Japan, NTT uses 1452 byte MTU for PPPoE and 1500 byte MTU for IPv6 on the same network). ok yasuoka@

2010-09-13Using a normaly unavailable 0.0.0.1 gateway on routes on sppp(4) basedClaudio Jeker
devices is a bad idea. The problem is that the default route per se works but PMTU is unable to clone host routes because the gateway is unreachable. Fix sppp(4) so that it walks the routing table and fixes the gateways. This makes PMTU work again. Diff tested by weerd@ and markus@ (older version) for a long time.

2009-11-03rtables are stacked on rdomains (it is possible to have multiple routingClaudio Jeker
tables on top of a rdomain) but until now our code was a crazy mix so that it was impossible to correctly use rtables in that case. Additionally pf(4) only knows about rtables and not about rdomains. This is especially bad when tracking (possibly conflicting) states in various domains. This diff fixes all or most of these issues. It adds a lookup function to get the rdomain id based on a rtable id. Makes pf understand rdomains and allows pf to move packets between rdomains (it is similar to NAT). Because pf states now track the rdomain id as well it is necessary to modify the pfsync wire format. So old and new systems will not sync up. A lot of help by dlg@, tested by sthen@, jsg@ and probably more OK dlg@, mpf@, deraadt@

2009-07-13Do the same rdomain checking in sppp as we do in the Ethernet case.Claudio Jeker
Encapsulated pppoe packets are moved into the rdomain of the physical interface because it is possible that a pppoe(4) interface is in a different rdomain then the physical interface. OK reyk@

2007-12-041500 is a 'magic number' in the protocol that all implementationsClaudio Jeker
must be able to handle as MRU but while testing pppoe(4) against a pppoe(8) server I figured out that pppoe(8) insists on a MRU 1492. Because of this we allow the offered MRU to be between PP_MIN_MRU and PP_MAX_MRU especially because the MRU is not used at all as long as it is smaller then PP_MAX_MRU. OK canacar@
