Sounds like an Advent of Code puzzle, for grepping through
/cvs/CVSROOT/ChangeLog*

The answer for Part 1: sum of base (src) commits so far in 2020 is 7582. 
Part 2 to figure out which committer has the most commits in 2020 is 
left open as excercise for the reader. Hint it's ~740 commits.

According to SMBIOS Reference Specification, you are correct.
  7.2.1
  Although RFC 4122 recommends network byte order for all fields, the PC 
industry (including the ACPI,
  UEFI, and Microsoft specifications) has consistently used little-endian byte 
encoding for the first three
  fields: time_low, time_mid, time_hi_and_version. The same encoding, also 
known as wire format, should
  also be used for the SMBIOS representation of the UUID.
  The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented as:
  33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.

What are the ramifications of a changed UUID?
What software depends on hw.uuid not changing? 

Greetings Ben

With the virtio modules now included in the installer you can skip my
tutorial. You only need to change bootparameters in GRUB to pass
vga=off console=ttyS0,115200n8 to the linux kernel.

As for DHCP, it depends on your config: is pf blocking DHCP traffic?
is the bridge/switch interface set up correctly?
is sysctl net.inet.ip.{m,}forwarding set to 1?
do you use vmctl -L (local interface)?

Here is how I got debian 9 (stretch) installed.

I think the virtio-modules are now included in the debian 10 (buster)
installer, but not tested.

Have made the same adjustments here. Works good.
Do you have an old usbhidaction running in background, that blocks /dev/uhid1

I do have multiple users set up on my machine for this purpose (chrome and

#start browser
cd /home/chrome &&

Well, from reading the code a little seems the keydisk metadata is at offset
SR_META_OFFSET = 8192 bytes and is SR_META_SIZE (64) * DEV_BSIZE (512 bytes) = 
32768 bytes long.

Time ran out so do what you will with it. This is untested and always keep a 
good backup.

True. 2 years ago smtpd defaults switched from db to file based tables.

Because backwards compatibility: newaliases(8), makemap(8), sendmail(8)
and mailq(8) are all symlinks to mailwrapper(8) which then runs smtpctl(8).

This will knock the disk cache down to 5% of RAM space.
You can not go lower, so a reboot between tests is the best way
to have a clean state.
Default is 20%, max. is 90% (which I use).

Just the one buffercache.

It compares /bsd with checksum in /var/db/kernel.SHA256
if it does not match kernel relinking is disabled because it
assumes you are a kernel developer and know what you are doing.

Not really.

Oh it's been only 9 month since bioctl(8) switched over to bcrypt PBKDF.
You might run a older version (dmesg would help) in which case you want
to go much higher... 16000? 

# bioctl -v -c C -l /dev/vnd0a softraid0

shows you what KDF you are using.

Yes you are measuring your typing speed.

clang(1) not picking up headers from /usr/include

[Benjamin Baier]

Hello,

what am I doing wrong?

clang(1) from ports claims to look under /usr/include by default [0] but for
me it doesn't work unless -I/usr/includes or C_INCLUDE_PATH=/usr/include
is defined.
After that I even hacked around in InitHeaderSearch.cpp[1] but no luck so far.

Greetings Ben

Adding new printer on the CUPS webinterface does not "like" this 
malloc option. It doesn't crash, it just doesn't work.

Subtle breakage like this might occure when you "set and forget" this
feature. I guess thats why it is labled "for security auditing".

Building packages is only half as bad as it used to be since the pmap and cache

Have my stereo connected and I use OpenBSD for audio/video playback exclusively
for over a year now. Very nice overall audio integration. 
With Pulseaudio I always had the need to fiddle with the mixer to get audio
volumes the way I want them. Now I just have to controll the master volume,
because on OpenBSD the applications behave like they should.

Hi and thanks, 
please let me share my modifications for wifi handling, too.

This patch to /etc/netstart [0] cycles through different configurations

Had a similar "problem" on a recent install.
The hardware clock was so out of date, that a ntpd -s refused to set
the time because of ...ssl certificates not yet valid...

Solution one disable constraint check and run ntpd the old fashioned way
for the first few minutes. Or second solution, set the date once by hand
and then run ntpd with constraint checks.

You might get a new one, because your batterie might be a fire hazard.

You skipped the snapshots with libc 81 [0] in it (Aug 26 - Sep 9).
Wait for the packages to be build with 82... should not be long.

 I have never seen fluent browser HTML5 video on any OpenBSD machine.
 Generally, videos at a fair resolution on OpenBSD played back without
 use of xvideo extensions or OpenGL are not watchable.
I might have gotten luky but this Thinkpad X220 plays 720p Youtube HTML5
video in Chromium without glitches, even on fullscreen.
As long as there is no other system load.

 My theory is that browsers rely on fast multi-core CPUs and multihreading in
 the kernel to show video smoothly. OpenBSD doesn't have multihreading in
 the kernel and is tuned for correctness rather than performance.
 
 Did anyone try playing HTML5 video in a browser on a slow (= 1Ghz) single
 core machine running Linux? Would you expect that to work?

Re: Sluggish/laggy browser behaviour

[Benjamin Baier]

 I can pretty much confirm this on an X220i, I have sort of come to terms
 with it, but it is definitely noticeable (in chromium and firefox).
X220 here.

 Also, when I play clips on YouTube, playback sometimes hangs for half a
 second. That is with a snapshot from today. To be safe, I also
 recompiled sndio from CVS to make sure I didn't miss the previously
 mentioned patch. While it does seem to have improved the situation, it's
 not entirely fixed.
Noticed this, too. Running with hw.perfpolicy=high solves it for me,
unless there is heavy disk I/O then it starts stuttering again.

 My guess is that this is due to missing SMP features/support, but I'm
 not entirely sure.
My guess is that disk I/O takes precedence, and cpu C-state transitions
should be avoided while audio/video playback...

 Hi again,
 
 at first I was not sure that I had connected it properly, since neither
 you program nor gpioctl(1) seemed to work. Then I tried Debian, with
 which I also couldn't get GPIO to work (using /proc/sys/class/gpio). But
 using the library descriped in
 https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/g
 pio
 and the example program seemed to work (of course after switching to pin
 10). Can you tell me what is the correct way to access GPIO pins on
 OpenBSD? I did:
 gpioctl gpio1 6 2
 Later I also set flag:
 gpioctl gpio1 6 set out
 But changing states still didn't work.
 
 Thanks, for your help,
 Piotr Kubaj.

Hi,

if i remember correctly on Beaglebone Black the 4 on-board-leds are
numberd from 21 to 24. 
If you read the manpage for gpioctl carefully you'll find that
Only pins that have been configured at securelevel 0, typically 
during system startup, are accessible once the securelevel has been raised.
So put this in your /etc/rc.securelevel
gpioctl gpio1 21 set out

Then once logged  in, this
$ gpioctl gpio1 21 0
should turn the first led off, assuming the user has proper rights for 
/dev/gpio1

Also for testing I prefer the system not to raise the securelevel after boot,
so securelevel=0 in /etc/rc.securelevel

Greetings Ben

Hi,
How can I use libressl with a python2.7 programm on current?

The python program use import OpenSSL, and I tried replace OpenSSL with Libtls and 
Libressl, but none can be found.

Searched Misc, Tech and FAQ, didn't find anything helpful.

Thanks.

Thanks. I tried it but I now get

Clearly I can just let it be, but it's puzzling, particularly as it
happens right after a fresh install. Any other suggestions will be
welcome.

Thanks again,

Re: Thanks for ksh

Is this because of the newest bash-shellshock (CVE-2014-6271)?

Nevertheless. Thanks for doing things right.

Re: minimums for /usr/ports, /usr/xenocara, and /usr/src

[Benjamin Baier]

Here are the newest numbers i can provide for a full build from source.
/usr/src 900MB
/usr/xenocara 700MB
/usr/obj 900MB
/usr/xobj 500MB
/usr/ports 600MB
/usr/ports/pobj can't be big enought...

I'm trying re-learn how to bring a new install up to -stable, and I've
been following the instructions on

http://www.openbsd.org/stable.html

and

http://www.openbsd.org/faq/faq5.html#Bld

and not doing a very good job of it. The recommended partition left me
with only 1.4G for /usr, and it was 90% full when I finished unpacking
the sys, src, ports, and xenocara tarballs.

(ancient IBM thinkpad with only 256M RAM and 20G (17 real gig) or hard
disk. 860 MHz or so CPU.)

I had saved 2.5G out of the suggested size for /home, so I cut a 1G
partition for /usr/ports and gave it the default newfs. mount on /mnt,
cp -pR /usr/ports/ /mnt/ (I always mess that up -- mv /mnt/ports/*
/mnt; mv /mnt/ports/.cvsignore /mnt.) Deleted the original contents
of /usr/ports, which I now see was a mistake, and mounted the new
partition on /usr/ports.

And then I did a cvs co on src, ports, and xenocara.

About an hour later, it tells me I have no inodes left on ports. df
-ih tells me I have 398 M used on /usr/ports, which is 42%, but
155,676 inodes in use, which is 100%. I forgot to write down what it
was trying to check out when it ran out.

/usr/src looks like its complete, with 111,613 inodes in use and
70,273 free, 1.2G partition with 313M free. I'm thinking that's room
enough to build the patches and a few other things I need.

What size partition should I cut for /usr/ports, and how many inodes
should I allocate it? Or should I just not try to bring /usr/ports up
to stable?

And what can I expect for /usr/xenocara? Just from unpacking the
tarball, it's using close to 700M on /usr, so I'm planning on cutting
it a partition, too.

My thinking is to use my remaining 1.5G for a new /usr/ports, give it
500,000 inodes and cp -pR again, to save bandwidth on the mirror, then
take the 1 G partition that would be freed, give it 300,000 inodes,
and use it for /usr/xenocara.

Can anyone tell me if that will be enough?

Or maybe I should just do it the other way, from the patch sets, I think it was.

(1) With DVC it's easy to alter history and it's easy to get the

Everybody has a local copy of the repository so if somebody alters 
history locally and force pushes it to the central repository, it's 
broken for the rest of the developers. So you are just one force push 
from another developer away from having your original state back. Your 
team needs 100% approval rate to alter history.



AFAIK:
 rcs - trivial to change the past (also not distributed, and NFS is
undesirable).
 cvs - reasonably easy to change the past, usually.
 svn - definitely possible (AFAIK) to change the past.

not distributed


 bzr - unknown
 hg - unknown
 git - unknown
 everything else - unknown.

fossil comes to mind, too.


For this application, a file-oriented system would be preferred over a
snapshot-oriented system like git.
git uses files. They are named after their checksums and they are 
compressed.

what do you mean with file-oriented vs. snapshot-oriented


I'm trying to combine (soft) WORM-like properties with the benefits of a
version control system.  Does not need to be utterly secure, merely
needs to be good enough to deter both script-kiddie level attackers
and inebriated sysadmins.
CVS would be ideal except that access control is AFAIK basically ternary
(none,read,write).

WORM as in Write Once Read Many... Well DVC have the notion of an directed
acyclic graph with is protected by hashsums against alteration,
so (1) comes to mind.


Should ideally be in packages or ports, obviously.  We have a bunch of
version control systems in ports that I've never even heard of before!

Suggestions on which one I should learn how to configure?
git is the hip thing right now and you can do _everything_ with it, but 
be aware it has more knobs than a Boeing 777.


But maybe all you need is CVS (and a plan), who knows?

Hi misc@,

i face a problem with zenity (from ports).  I use it to read a string via a
nice graphical popup (in my case, the url to a youtube video, which then gets
opened in fullscreen mplayer).

Gnome is installed on my machine, although i don't use it very often.  Anyway,
zenity has a few dependencies on gnome (see http://ports.su/x11/gnome/zenity),
and when i'm logged in to gnome, zenity starts within a second.

Now, i seldomly use gnome, but dwm instead (a simple tiling manager).  Also, i
start dwm directly with a 'xinit' from the terminal, while i use gdm for
gnome.

 From dwm, zenity takes ~7 seconds (!) to start.  The whole system is installed
on a ssd (samsung 830) for that matter.  Even worse, the startup time stays
like that, whenever i (re)start zenity, so everything the system had to load
seems to be gone immediately after the program exits.


Suggestion: ditch zenity and use yad (ports/x11/yad) instead...

my 2 cents,
David



Thanks, i just tried yad, but it needs ~7 sec to start as well (from the command
line), so no improvement :(

Re: long file names with tar

[Benjamin Baier]

The exact error message is always helpfull.
Nevertheless, see man 1 pax and search for ustar
GNU tar uses a extended tar format to store longer pathnames.

I see you compile the kernel by yourself, GENERIC.MP is what you want.

Re: Updating sets

1. Know your mirror:
A person who wants to do that should find out the
policies of making snapshots for a particular mirror.

Depending on the architecture, mostly once a day. Which is enough!
I mean the OpenBSD userland. Package snapshots take a little longer 
between updates.



3. Shake, don't mix
If one commits to usage of -current kernel with
snapshot ports, best effort should be put in avoiding port
compilation.

I don't understand that.
Following current (kernel, base system and X11) can be done by upgrading 
using the snapshot sets from the mirrors. Using bsd.rd's upgrade and 
then sysmerge is the preferred way.
Packages are precompiled ports which also is the preferred way of 
getting 3rd party software on your OpenBSD install.



4. pkg_add -U shouldn't be used
Partial update of the system is dangerous
and as we don't have control over the source of
snapshots, an upgrade followed by full update should
be done as a part of installation of new package.
So true, when pkg_add can't install a package it's probably time for a 
upgrade.



Now that I think about it, I realize that it's unlikely that I'll
keep using this weird build kernel, download pkgs
combination and will simply do snapshot hopping by
means of upgrade/sysmerge.
Nevertheless, compiling and upgrading/updating your system and ports 
from source is fun and a great way to learn = this translates to 
breaking your system is fun and you learn from mistakes.

Re: Ralink mystery usb mini WiFi adapter

[Benjamin Baier]

It's Advertised as an EP-N8508.
It is most likely a rebrand, which uses the rtl8188cus (very low cost chip)
This should be supported by the urtwn driver.
Just need to recognize the USB device number.
In this case it's idVendor 0x148f idProduct 0x7601.

This makes me wonder, if there is a method to test this without 
recompiling the kernel.

With config(8) maybe?

If you want, I'll stick it back in its padded envelope and send it to
you to experiment on. I think I'd like it back someday but if it won't
work under OpenBSD it's useless.  I hope to know by tomorrow if it
works under FreeBSD 10 on my Raspberry Pi but otherwise I could only
use it under Windows. Email me a snail mail address if you want it.

Looking closer, it seems to be a run(4) variant.
At least the vendor driver groups it with other run(4) devices.

That doesn't mean it will work without modifications, though.
It seems to need a different firmware at least. Whether or not
it is backwards compatible to older devices is hard to tell
without spending a lot of time digging around in the vendor
sources... But there are other run devices we don't yet support
