* Add feature to force the selection of source IP addressdenis2020-10-291-2/+4

* prepare sysctl net mib to allow runtime tuning of rx q pressure thresholdsdlg2019-07-031-2/+25
| | | | | | | | | this renames the PF_LINK bit of the mib from "link_layer" to "link". then it makes it a node that could be used for generic link layer bits. the first of these is an "ifrxq" node where the "pressure_return" and "pressure_drop" things go. ok visa@ deraadt@
* AF_LOCAL was a failed attempt (by POSIX?) to seem less UNIX-specific, butguenther2018-04-081-4/+4
| | | | | | | AF_UNIX is both the historical _and_ standard name, so prefer and recommend it in the headers, manpages, and kernel. ok miller@ deraadt@ schwarze@

* Automatically create a default lo(4) interface per rdomain.mpi2016-11-141-2/+4
| | | | | | | | | | | | | | | | | | In order to stop abusing lo0 for all rdomains, a new loopback interface will be created every time a rdomain is created. The unit number will be the same as the rdomain, i.e. lo1 will be attached to rdomain 1. If this loopback interface is already in use it wont be possible to create the corresponding rdomain. In order to know which lo(4) interface is attached to a rdomain, its index is stored in the rtable/rdomain map. This is a long overdue since the introduction of rtable/rdomain. It also fixes a recent regression due to resetting the rdomain of an incoming packet reported by semarie@, Andreas Bartelt and Nils Frohberg. ok claudio@

* At guenther's suggestion replace dnssocket() with a SOCK_DNS flag onderaadt2015-10-201-2/+3
| | | | | | | | | socket(). Without pledge, all other socket behaviours become permitted, except this one case: connect/send* only works to *:53. In pledge mode, a very few are further restricted. Some backwards compatibility for the dnssocket/dnsconnect calls will remain in the tree temporarily so that people can build through the transition. ok tedu guenther semarie

* Fix the naming of interfaces and variables for rdomains and rtablesguenther2010-07-031-4/+4
| | | | | | | | | | | | 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.

* Add SO_BINDANY socket option from BSD/OS.markus2008-05-091-1/+2
| | | | | | | | | The option allows a socket to be bound to addresses which are not local to the machine. In order to receive packets for these addresses SO_BINDANY needs to be combined with matching outgoing pf(4) divert rules, see pf.conf(5). ok beck@

May be of use to those interested in precision network timing schemes or QoS for media applications. Tested on alpha, amd64, i386 and sparc64. manpage suggestions from jmc, ok deraadt
* Import MPLS (Multi Protocol Label Switching)norby2008-04-231-3/+6
| | | | | | | | | | | | | MPLS support partly based on the (abandoned?) AYAME project. Basic LSR (Label Switch Router) functionality is present, but not fully functional yet. It is currently possible to insert entries in the LIB (Label Information Base) with route(8), but setting the operation type is not supported yet.

| | | | | | | | | | | | | | on the local network support them. This adds a new socket option, SO_JUMBO, and a new route flag, RTF_JUMBO. If _both_ the socket option is set and the route for the host has RTF_JUMBO set, ip_output will fragment the packet to the largest possible size for the link, ignoring the card's MTU. The semantics of this feature will be evolving rapidly; talk to us if you intend to use it. ok deraadt@ marius@
