What's NewThis is a partial list of new features and systems included in OpenBSD 4.6. For a comprehensive list, see the changelog leading to 4.6.
* New/extended platforms:
o mvme68k
+ Added support for the MVME141 and MVME165 boards.
o sparc
+ The bootblock load address was moved so that larger kernels can be loaded.

o Added support for 82574L based devices in the em(4) driver.
o A number of network drivers including ix(4), sis(4), msk(4), bnx(4), and vr(4) now use MCLGETI(9) to reduce memory usage and increase performance under load and attack.
o Added support for VIA CX800 south bridge to the viapm(4) driver.

o New berkwdt(4) driver for Berkshire Products PCI watchdog timers.
o New udl(4) driver for USB video devices.
o Support for a variety of newer models in bge(4).
o Initial version of vsw(4), a driver for the virtual network switch on sun4v sparc64s.
o Implemented machfb(4), an accelerated driver for the sparc64 PGX/PGX64 framebuffers.
o Added a vcc(4) and vcctty(4) driver for the "Virtual Console Concentrator" found on the control domain of sun4v systems.
o Implemented 64-bit FIFO modes for ciss(4) devices.
o Enable hardware VLAN tagging/stripping on ix(4).
o Added basic support for Envy24HT chips in the envy(4) driver.
o Many improvements and updates to the isp(4) driver.
o Added support for 88E8057-based Yukon 2 Ultra 2-devices in msk(4).
o The ips(4) driver now works reliably.
o Added raptor(4), an accelerated framebuffer driver for the Tech Source Raptor GFX cards on the sparc64 platform.
o Enabled schsio(4) on i386 and amd64 and added watchdog timer support.
o New acpivideo(4) driver for ACPI display switching and brightness control.
* New tools:
o Added smtpd(8), a new privilege-separated SMTP daemon.
o Imported the tmux(1) terminal multiplexer, replacing window(1).
* pf(4) improvements:
o Enabled pf(4) by default in the rc.conf(8).
o Removed pf(4) scrub rules, and only do one kind of packet reassembly. Rulesets with scrub rules need to be modified because of this.
o Regular rules can now have per-rule scrub options.
o Added new "match" keyword which only applies rule options but does not change the current pass/block state.
o Make all pf(4) operations transactional to improve atomicity of reloads.
o Stricter pf(4) checking for ICMP and ICMPv6 packets.
o Various improvements to pfsync(4) to lower sync traffic bandwidth and optionally allow active-active firewall setups.
o Fix pf(4) scrub max-mss for IPv6 traffic.
* OpenBGPD, OpenOSPFD and other routing daemon improvements:
o In bgpd(8), rework most of the RDE to allow multiple RIBs. It is possible to filter per-RIB and attach neighbors to a specific RIB.
o Added an option to bgpd(8) to change the "connect-retry" timer.
o Allow bgpd.conf(5) and bgpctl(8) to contain 32-bit ASN numbers written in ASPLAIN format.
o Fix bgpd(8) to correctly encode MP unreachable NLRI so IPv6 prefixes get removed correctly.
o Changed the behaviour of "redistribute default" for ospfd(8) and ripd(8). A default route has to be present in the FIB to be correctly advertised.
o Make ospfd(8) and ripd(8) track reject and blackhole routes and allow them to be redistributed even if pointing to 127.0.0.1.
o Allow to specify an alternate control socket for ospfd(8).
o ospfd(8) can now be bound into an alternate routing domain.
o Fix ospfd(8) route metric for "redistribute default".
o Initial version of ldpctl(8) and ldpd(8), a label distribution protocol daemon for mpls.
o Make dvmrp(8) RDE aware of multicast group members per interface.
o Support for pruning in dvmrp(8).
* Generic Network-Stack improvements:
o Support for virtual routing and firewalling with the addition of routing domains.
o Add code in ifconfig(8) to bind an interface to a routing domain.
o Add support to ping(8), traceroute(8), arp(8), nc(1) and telnet(1) to specify which routing domain to use.
o Allow ifconfig(8) to turn off IPv6 completely for an interface and make rtsold(8) turn on inet6 on the interface.
o Routes track the interface link state.
o route(8) flush accepts "-iface" or "-priority" to only flush routes matching these conditions.
o Multiple dhclients can now coexist without causing mayhem.
o Make wireless interfaces have an interface priority of 4 by default. Makes them less preferred then wired interfaces.
o Do not accept IPv4 ICMP redirects by default.
o Added the MAC address to the log entries in dhclient(8).
o Make systat(1) show interface description names in the interface view, and add new NFS server and client views.
o Make tun(4) emulate link state depending on the open and close of the device fd.
o Use pf state-table information to speed up decision on whether a packet is to be delivered locally or forwarded.
o More routing socket checks added to make userland applications more resilient to kernel changes.
* Install/Upgrade process changes:
o New disklabel(8) automatic partition allocator with a variety of smart heuristics.
o The installer has been nearly rewritten mostly with a focus on simplifying installation.
* OpenSSH 5.3:
o Do not limit home directory paths to 256 characters. (bz #1615)
