Changes made between OpenBSD 6.0 and 6.1

• Disabled smtpd(8) client-initiated renegotiation.
• Used m_devget(9) to replace ure(4) code which incorrectly assumes a received packet must fit into a single mbuf cluster, potentially fixing observed pool corruption.
• Set the interface flag to VMIFF_UP when using the vmctl(8) -i option, making vmd(8) ensure the interfaces are up on startup.
• Allowed additional protocol matching to enable umodem(4) to attach to the serial console on the OverDrive 1000.
• Fixed a panic triggered by init(8) on the OverDrive 1000 with A1120 (Cortex A57 r1p2) after changing vfp state.
• Prevented editing messages in mail(1) from corrupting the mailbox.
• Stopped rejecting etherip(4) packets protected with ipsec(4).
• Added iked(8) support for RFC 4754 (ECDSA) and RFC 7427 authentication.
• Fixed the prefixlen sent by RTM_NEWADDR on new addresses without masks.

• Updated to Mesa 13.0.6.
• Implemented mvxhci(4), a driver for Marvell's XHCI controller, and mvahci(4), for Marvell's AHCI controller. These enable use of USB and SATA, respectively, on devices like the SolidRun ClearFog or Omnia Turris.

• Handled interrupts after retiring a cpuid instruction, allowing vmd(8) to proceed.
• Implemented kernel W^X for arm64.
• Added tmux(1) support for the strikethrough attribute (SGR 9).
• Prevented unusable configurations where both WEP and WPA are active by disabling one when a key for the other is set.
• Fixed errors in NS8250 (UART) vmm(4) emulation that had caused seabios not to be able to output data.
• Showed inet6 proposals in route(8) monitor.
• Read the free clusters bitmap in 1MB chunks, rather than attempting to read it all together, causing a panic in malloc(9) with large NTFS filesystems.

• Released OpenSSH 7.5.
• Enabled snooping on Kaby Lake U/Y PCH HDA in azalia(4) to avoid audio glitches.

• Ported ctags-style, less(1) :t internal searching from terminal output to HTML output in mandoc(1).
• Printed title="..." in addition to id="..." attributes for macro keys in mandoc(1) that can be searched for by apropos(1), such that the semantic function appears in a tooltip when hovering with the mouse.
• Resolved simultaneous IKE and Child SA rekeying in iked(8).
• Made ifconfig(8) "scan" show WPA information for other APs correctly while the interface operates in hostap mode.
• Stopped limiting physmem to 2GB on arm64.

• Added copying of the rpi3 u-boot to the installed disk to the arm64 ramdisk installer.
• Prevented mandoc(1) memory exhaustion due to user-defined macros exceeding the stack limit by discarding what remains in the open stack levels on abort.
• Used the target mask for the boot CPU upon ampintc(4) attachment to pick the target CPU interface when establishing an interrupt, allowing interrupts to work on machines that boot up on a CPU attached to a CPU interface that isn't zero.
• Changed priq enqueue policy to drop lower priority packets, allowing high priority traffic a place in the queue and low priority bulk traffic a chance to regulate its throughput.
• Corrected handling of TLS PRF with MD5+SHA1 in ssl(3).

• Updated to Unicode 8.
• In 11n hostap mode, dynamically adjusted HT protection settings based on the presence of non-HT nodes in the node cache. OpenBSD 11n APs will now disable HT protection if it is not necessary. Fixed display of HT protection settings in tcpdump(8).

• Added a "locked lladdr" option in vm.conf(5) to prevent VMs from spoofing MAC addresses.
• Allowed MPLS switching and VPLS across rdomains.
• Fixed a bug allowing a man-in-the-middle attack against WPA wireless clients. A malicious AP could trick clients into connecting to itself rather than the desired AP, then all frames would be sent in the clear.
• Added an "owner" option to vm.conf(5) to set user/group ownership for pre-configured VMs, allowing matching users console access and the power to start/stop VMs.
• Dynamically attached edma(4) using the FDT.
• Created the /etc/installurl file during upgrade if a mirror was used and the file did not yet exist.
• Modified the installer logic to determine the default answer for the "Location of sets?" question. Presents "http" as the default answer if /etc/installurl exists, correcting an issue where "cd" was overriding "http".
• Handled touchpad input in wsmouse(4).
• Bumped block size for dd(1) for arm64, for a substantial speed increase.

• Bumped the default size of the MSDOS partition on octeon from 16MB to 32MB.
• Used memcpy(3) a character row at a time to the framebuffer in rasops(9), rather than sending pixel by pixel. This greatly speeds up the text framebuffer on some EFI implementations.
• Fixed asynchronous system traps on arm64, allowing processes to be killed using Ctrl-C.
• Restored a local change to xkeyboard-config(7) to handle Ctrl-Alt-Backspace to kill X by default.

  • run "make config" to use the logic in ../Makefile.inc to re-run config with the correct -b options, creating a layout in obj/
  • exit 0
