* Store a unique ID, an interface index, rather than a pointer to thempi2015-06-161-2/+2
| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@

* Include the timestamp TCP option in keep alive packets as well.mikeb2015-05-071-8/+17
| | | | | | | | | | According to RFC 7323 "once TSopt has been successfully negotiated, ... [it] MUST be sent in every non-<RST> segment for the duration of the connection." Which means that keep alives which are just ACK packets must include that too. Pointed out and tested by Lauri Tirkkonen <lotheac at iki ! fi>, thanks! ok mpi

* "struct pkthdr" holds a routing table ID, not a routing domain one.mpi2014-04-141-4/+4
| | | | | | | | | | | | | | Avoid the confusion by using an appropriate name for the variable. Note that since routing domain IDs are a subset of the set of routing table IDs, the following idiom is correct: rtableid = rdomain But to get the routing domain ID corresponding to a given routing table ID, you must call rtable_l2(9). claudio@ likes it, ok mikeb@

| | | | | | | | | | already there, just compute it - it's dirt cheap. since that happens very late in ip_output, the rest of the stack doesn't have to care about checksums at all any more, if something needs to be checksummed, just set the flag on the pkthdr mbuf to indicate so. stop pre-computing the pseudo header checksum and incrementally updating it in the tcp and udp stacks. ok lteo florian

* The function rip6_ctlinput() claims that sa6_src is constant tobluhm2013-05-311-6/+6
| | | | | | | | | | allow the assingment of &sa6_any. But rip6_ctlinput() could not guarantee that as it casted away the const attribute when it passes the pointer to in6_pcbnotify(). Replace sockaddr with const sockaddr_in6 in the in6_pcbnotify() parameters. This reduces the number of casts. Also adjust in6_pcbhashlookup() to handle the const attribute correctly.

* Fix the naming of interfaces and variables for rdomains and rtablesguenther2010-07-031-16/+7
| | | | | | | | | | | | and make it possible to bind sockets (including listening sockets!) to rtables and not just rdomains. This changes the name of the system calls, socket option, and ioctl. After building with this you should remove the files /usr/share/man/cat2/[gs]etrdomain.0. Since this removes the existing [gs]etrdomain() system calls, the libc major is bumped.

| | | | | | | | needed so that the route and inp lookups done in TCP and UDP know where to look. Additionally in_pcbnotifyall() and tcp_respond() got a rdomain argument as well for similar reasons. With this tcp seems to be now fully rdomain save and no longer leaks single packets into the main domain. Looks good markus@, henning@
* rtables are stacked on rdomains (it is possible to have multiple routingclaudio2009-11-031-3/+2
| | | | | | | | | | | | | | 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@
* sockets created via a listening socket lose the rdomain and fail to workclaudio2009-08-101-3/+3

The same network can now be used in any doamin at the same time without causing conflicts. This diff is mostly mechanical and adds the necessary rdomain checks accross net and netinet.
