Re: ssh/sshd configuration parsing
I do not consider it necessarily a bug so I did not send this bugs@, but this did impact ProxyJump in my ~/.ssh/config. I'd formerly had: ProxyJump host, anotherhost This currently/now fails with "Invalid ProxyJump". Re-checking the ssh_config manual page though I saw the clarification of "separated by comma" - not "comma and whitespace". That combined with IRC pointing me here got me back running again once I removed the whitespace and went to: ProxyJump host,anotherhost Not a complaint just wanted to make breadcrumbs for anyone else searching for the same new behaviour.

setitimer(2): increase interval upper bound to UINT_MAX seconds
Hi,
setitimer(2) has a one hundred million second upper bound for timers.
Any timer interval larger than this is considered invalid and we set
EINVAL.
There is no longer any reason to use this particular limit. Kclock
timeouts support the full range of a timespec, so we can trivially
increase the upper bound without any practical risk of overflow.
This patch increases the upper bound to UINT_MAX seconds.
Why UINT_MAX? UINT_MAX is the largest possible input to alarm(3). We
could then simplify the alarm(3) manpage and the libc alarm.c code in
a subsequent patch. POSIX says alarm(3) "is always successful". Our
implementation can fail. It would be nicer/simpler if ours were free
of failure modes.
ok?

I can't find 0xf0c8 in the datasheets either.
I've committed this but moved the added line in pcidevs to maintain
ordering by device id. Thanks for the patch.

Re: Document missing pledge promises
Regarding the vmm chunk -- as I said in my other reply, these
explanations are too precise. They risk becoming outdated as things
change. Furthermore, some of those ioctl may work in one way, but not
another way. Which would be too complicated to describe also. I urge
simple messaging:
.It Va vmm
Operations required by
.Xr vmd 8 .
It is accurate. If someone later wanted to use those operations, they
would figure it out by reading kernel and vmd source.

Document missing pledge promises
Here's my take at documenting the missing pledge promises in pledge.2
and placing them in a reasonable order with the others. Each of these
just enabled various ioctl or sysctl interfaces.
I'm unhappy with the explanation for drm, but don't know how to
explain the purpose of these ioctls, and could not find any man page
to .Xr which documents these ioctl commands.

dhcpleased(8): handle gateway outside configured address prefix
I hear there are circuses out there where the dhcp server hands us a /32
and so the default gateway is not reachable.
The comment in sbin/dhclient/kroute.c suggests that the Google Clown
Platform operates in this way. I seem to recall mumblings that Hetzner
does something similar on their VPS.
Currently dhcpleased(8) will not work in such setups, I think this diff
fixes it. Could someone tests this please in the real world?
(This is currently two diffs in one, a bunch of deck chair shuffling and
fixing the actual problem. I'll work on classes static routes option
next to see if the deck chairs have been shuffled sufficiently. Not
asking for OKs just yet.)

sysupgrade reset option
I am likely going to simply track file changes and revert them for a reset to factory defaults facilitation, rather than maintaining a build system for a custom bsd.rd. One assumption that I have made is that newfs and dd altroot to root and reboot in rc.securelevel would fail or be problematic? Is there any chance that OpenBSD would be interested in patches to add an unattended install option similar to how an auto_upgrade.conf is detected but where an /auto_install.conf is detected? I believe that the current autoinstall procedure requires interactivity (A) key or netboot.

fix isascii(3) manpage
All the is*() ctype.h functions take an int as argument, but valid values are only EOF, and the range of values of `unsigned char'. All, but one: the XPG4 isascii(), which has no such restriction. Quoting https://pubs.opengroup.org/onlinepubs/9699919799/ : ``The isascii() function is defined on all integer values.'' Hence the following diff.
