What's New

This is a partial list of new features and systems included in OpenBSD 4.5.

• New/extended platforms:
  • Initial ports to the xscale based gumstix platform and the ARM based OpenMoko
  • OpenBSD/sparc64
    New vdsk(4) and vnet(4) drivers provide support for virtual I/O between logical domains on Sun's CoolThreads servers, including UltraSPARC T2+ machines. Workstations and laptops with UltraSPARC IIe CPUs can now scale down the CPU frequency to save power.

• Improved hardware support, including:
  • Several new/improved drivers for sensors, including:
    • schsio(4), a driver for SMSC SCH311x LPC Super I/O devices was added.
    • gpiodcf(4), a driver for DCF77/HBG timedelta sensors through GPIO pins was added.
    • The it(4) driver now supports IT8720F chips.
    • The it(4) driver now supports FAN4 and FAN5 sensors for IT8716F/IT8718F/IT8720F/IT8726F chips.
    • The owtemp(4) driver now supports Maxim/Dallas DS18B20 and DS1822 temperature sensors.
  • The em(4) driver now supports ICH9 IGP M and IGP M AMT chips.
  • The sdmmc(4) driver now supports SDHC cards.
  • The msk(4) driver now supports Yukon-2 FE+ (88E8040, 88E8042) based devices.
  • The iwn(4) driver now supports Intel WiFi Link 5100/5300 devices.
  • The wpi(4) and iwn(4) drivers now support hardware CCMP cryptography.
  • The ath(4) driver now has WPA-PSK support.
  • age(4), a driver for Attansic L1 gigabit Ethernet devices was added.
  • ale(4), a driver for Atheros AR81xx (aka Attansic L1E) Ethernet devices was added.
  • mos(4), a driver for Moschip MCS7730/7830 10/100 USB Ethernet devices was added.
  • jme(4), a driver for JMicron JMC250/JMC260 10/100 and Gigabit Ethernet devices was added.
  • run(4), a driver for Ralink USB IEEE 802.11a/b/g/Draft-N devices was added.
  • auacer(4), a driver for Acer Labs M5455 audio devices was added.
  • ifb(4), a driver for Sun Expert3D, Expert3D-Lite, XVR-500, XVR-600 and XVR-1200 framebuffers (accelerated).
  • wildcatfb(4), an X driver for Sun Expert3D, Expert3D-Lite, XVR-500, XVR-600 and XVR-1200 framebuffers (unaccelerated).
  • sunffb(4), an accelerated X driver for Sun Creator, Creator 3D and Elite 3D framebuffers.
  • vdsk(4), a driver for virtual disks of sun4v logical domains.
  • vnet(4), a driver for virtual network adapters of sun4v logical domains.
  • vrng(4), a driver for the random number generator on Sun UltraSPARC T2/T2+ CPUs.
  • The vcons(4) driver is now interrupt driven.
  • ips(4), a driver for IBM SATA/SCSI ServeRAID controllers was added.
  • udfu(4), a driver for device firmware upgrade (DFU) was added.
  • Many improvements were made to the acpi(4) subsystem.
  • The umsm(4) driver supports several new EVDO/UMTS devices.
  • The mfi(4) driver now supports the next generation of MegaRAID SAS controllers.
  • New vsbic(4) driver for the MVME327A SCSI and floppy controller on mvme88k machines.
  • The re(4) driver, now supports 8168D/8111D-based devices.
  • The ehci(4) driver now supports isochronous transfers.
  • S/PDIF output support has been added to the ac97(4), auich(4), auvia(4) and azalia(4) drivers.
  • azalia(4) mixer has been clarified and simplified, support for 20-bit and 24-bit encodings has been added.

• New tools:
  • Sorry, this list is still being worked on.

• New functionality:
  • The libc resolver(3) may now be forced to perform lookups by TCP only using a new resolv.conf(5) option. The nameserver declaration in resolv.conf(5) has also been extended to allow specification of non-default nameserver ports.
  • apropos(1) has two new options (-S and -s) to allow searching by machine architecture and manual section.
  • aucat(1) now has audio server capability. Audio devices can be shared between multiple applications. Applications can run natively on fixed sample rate devices or on devices with unusual encodings. Multi-channel audio devices can be split into smaller independent subdevices.
  • aucat(1) now has a deviceless mode, in which it can be used as a general purpose audio file format conversion utility (to mix, demultiplex, resample or reencode files).
  • ifconfig(8) can now list channels supported by an IEEE 802.11 device.
  • Sorry, this list is still being worked on.

• Assorted improvements and code cleanup:
  • malloc(3) has gained new attack mitigation measures; critical bookkeeping structures are protected at runtime using mprotect(2) and allocated at random addresses where possible.
  • A new version of the gdtoa code has been integrated, bringing better C99 support to printf(3) and friends.
  • Vastly improved C99 support in libm, including complex math support.
  • Sorry, this list is still being worked on.

• Install/Upgrade process changes:
  • Sorry, this list is still being worked on.

• OpenSSH 5.2:
  • New features:
    • Added an option to ssh(1) to force logging to syslog rather than stderr.
    • The sshd_config(5) ForceCommand directive now accepts commandline arguments for the internal-sftp server.
    • The ssh(1) ~C escape commandline now support runtime creation of dynamic port forwards.
    • Support the SOCKS4A protocol in ssh(1) dynamic forwards.
    • Support remote port forwarding with a listen port of '0'.
    • sshd(8) now supports setting PermitEmptyPasswords and AllowAgentForwarding in Match blocks.
  • The following significant bugs have been fixed in this release:
    • Repair a ssh(1) crash introduced in openssh-5.1 when the client is sent a zero-length banner.
    • The eow@openssh.com and no-more-sessions@openssh.com protocol extensions are now only sent to peers that identify themselves as OpenSSH.
    • Avoid printing "Non-public channel" warnings in sshd(8), since ssh(1) has sent incorrect channel numbers since ~2004; make ssh(1) send the correct channel number for SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE.
    • Avoid double-free in ssh(1) ~C escape -L handler.
    • Correct fail-on-error behaviour in sftp(1) batchmode for remote stat operations.
    • Avoid hang in ssh(1) when attempting to connect to a server that has MaxSessions set to zero.

• Over 5500 ports, minor robustness improvements in package tools.
• Many pre-built packages for each architecture:
