Changes made between OpenBSD 7.5 and 7.6
- Fixed sleeping race during malloc in sysctl(2) hw.disknames.
- Removed sysupgrade(8) -r toggle. Sysupgrade's primary aim is to upgrade from one release to the next, with the -s option available to install snapshots.
- Increased the default buffer size for AF_UNIX from 8192 to 32768, avoiding a fatal error in sshd(8) that can be triggered when the network stack is pushed hard enough to consume most of the allowed memory.
- Added a temporary method to force S0 over S3 via machdep.lidaction=-1. We are not ready to choose S0-over-S3 based on the S0ix bit in FADT, but this will allow testing.
- Removed vmm(4) EPT mprotect ioctl.
- Allowed longer tx chains in vio(4) so we can defragment less often when TCP segmentation offload is supported.
- Moved rpki-client(8) to 9.3.
- Moved to openssh-9.9.
- Extended the zic(8) input format to add support for %z, which expands to a UTC offset in as-short-as-possible ISO 8601 format, intended to better support zones that do not have an established abbreviation already.
- Changed tmux(1) extended-keys behavior to allow applications to enter mode 2 but not turn extended keys off entirely.
- Added a tmux(1) prefix-timeout option to allow setting a period after which to ignore the prefix key if no others are pressed.
- Fixed kernel crashing due to invalid printables in ELF binaries.
- Kept radiusd(8) number of requests for a DAE server below 64 to avoid congestion.
- Added radiusctl(8) ipcp delete command to delete the specified session without requesting disconnection.
- Added a "Match invalid-user" predicate to sshd_config(5) Match options, allowing writing Match conditions that trigger for invalid username.
- Added a "refuseconnection" penalty class to sshd_config(5) PerSourcePenalties, allowing penalization of connection sources that have had connections dropped by the RefuseConnection option.
- Added a "RefuseConnection" option to sshd_config(5) to terminate the connection at the first authentication request.
- Included pathname in some of the ssh-keygen(1) passphrase prompts to better inform the user when ssh-keygen is invoked by other tools.
- Added NVMe sensors based on information in the SMART/health log page, showing overall device health and temperature.
- Made msdosfs transform a '/' char into '?' for 8.3 filenames as for Windows long names.
- Ensured file names passed back by readdir name validation do not include a '/' character to avoid unexpected path traversal on untrusted file systems.
- Relaxed absolute path requirement back to what it was prior to OpenSSH 9.8, which incorrectly required that sshd(8) start with an absolute path in inetd mode.
- Ignored tmux(1) mouse move keys to prevent accidental prefix cancelation.
- Implemented AMD SEC support in vmd(8). To enable SEV for a guest, use the parameter "sev" in the guest's vm section in vm.conf.5.
