Diff works as expected for me, and reads me good.  OK uebayasi@.

I admit I don't fully understand the intention of if_ih_* handler.  Can
you safely assume that there is always ether_input() hook just after
bridge_input()?

Re: FOSS tools for flashing motherboard BIOS?

[Alan Corey]

The hard drive I stick in when I want some operating systems on one
has XP Pro and OpenBSD 5.2.  OpenBSD 5.2 doesn't have libpci even in
ports so that rules out flashrom unless I want to try to build libpci
from sources (or a distfile).

I tried in XP safe mode running HP's sp40750.exe (which is a SoftPaq
like Compaq uses) and got:
  Can not open driver Flash1.sys.
  The driver is not existed or the OS is not in administrator privilege.

Flash1.sys is contained in sp40750.exe so it must be safe mode that's
killing me.

This is a Phoenix BIOS, not Award, hence the winphlash.  I think I'm
going to try the Vista drivers on HP's page, they might work with XP
and let me boot not into Safe Mode.

Sorry for the very slow replay to this message. Please see the dmesg for
the NUC. X works perfectly all 2560x1440 of it using HDMI cable. I
didn't connect the machine to the Internet so you will see that firmware
for WiFi on the bottom of dmesg is missing.

I meant flashrom, not flashboot (different topic).  Back in the days there
were also uniflash (abandoned) and some other (universal) flash utilities.

Because of the dozens of different machines on which this runs I'm not
sure that mine is one that has the problem.  I'd like to actually see
the warning before I decide not to use it.  Biosdisk is about 6 years
old so I decided to not go that route.  Of course the machine is about
10 years old and so is the BIOS image.

The manufacturer tools rely on Windows Vista which I don't have or
want.  If they had a more typical floppy image file I'd use it.  I
suspect it might run  under XP but I don't have a way to put XP on the
machine, since it's booting from CD/DVD I'm trying to fix.  Although I
do have a hard drive with XP on it from another machine which blue
screens on this one, maybe I can bring it up in safe mode or
something.  Especially if it doesn't need GUI.

OpenBSD uses the syncache for TCP sockets in the 3 way handshake to save a
lot of work to create a full socket in case of synfloods, etc.
These unhatched sockets do not show up in the netstat output. Maybe they
should be added but this is the first request that asks for them in the
10+ years we use the syncache.

That pbrowser is not available as a package (~7 months), its Makefile

If one utility warns you could potentially have unpredictable flashing
results, how is the other utility that does not warn you so different?

Tech support may not be engineering support, which you could then need.
Simply just use the manufacturer tools and not blame third party tools.

Re: Low brightness in text console

[Walter Alejandro Iglesias]

Another option (using current):

Section "Module"
Load"dri2"
Load"glamoregl"
EndSection

Section "Device"
Identifier  "Card0"
Driver  "intel"
BusID   "PCI:0:2:0"
Option  "AccelMethod"   "glamor"
EndSection

There are some Linux forums where people complain about experiencing
screen brightness issues using intel SNA acceleration.  Some of them got
them fixed by setting the "Backlight" option to the correct value as
explained in the intel(4) man page:

Option "Backlight" "string"
Override the probed backlight control interface. Sometimes the
automatically selected backlight interface may not correspond to
the correct, or simply most useful, interface available on the
system. This allows you to override that choice by specifying
the entry under /sys/class/backlight to use.

You won't find /sys/class/backlight in OpenBSD.  And setting the value
to "intel_backlight" as explained in some Linux wikis won't work since
in openbsd the interface seems to be wscons:

$ grep backlight /var/log/Xorg.0.log
[ 34783.393] (--) intel(0): found backlight control interface wscons

If after exiting X you run:

$ wsconsctl display.brightness

It'll return a value that doesn't correspond with the actual (very low)
brightness.  The wscons stored brightness value isn't reset but right
after you press the Fn+brightness keys.  I deduce SNA driver doesn't
pass wscons the brightness control properly.  Let's hope some expert
here tell us why. :-)

Re: FOSS tools for flashing motherboard BIOS?

[Alan Corey]

OK, so that's why it wasn't in pbrowser yet.  Running in single user
mode sounds like a pain.  Also the install puts the man page in
/usr/local/share/man/man8 .  And I haven't gotten to why it says not
to run on laptops yet.

Re: FOSS tools for flashing motherboard BIOS?

[Alan Corey]

>From flashrom's man page:

   Laptops

  Using flashrom on laptops is dangerous and may easily make your
  hardware unusable (see also the BUGS section). The embedded
  controller (EC) in these machines often interacts badly with
  flashing.  More information is in the wiki
  .  For example the EC firmware
  sometimes resides on the same flash chip as the host firmware.
  While flashrom tries to change the contents of that memory the
  EC might need to fetch new instructions or data from it and
  could stop working correctly. Probing for and reading from the
  chip may also irritate your EC and cause fan failure, backlight
  failure, sudden poweroff, and other nasty effects. flashrom will
  attempt to detect if it is running on a laptop and abort
  immediately for safety reasons if it clearly identifies the host
  computer as one. If you want to proceed anyway at your own risk,
  use

flashrom -p internal:laptop=force_I_want_a_brick

  We will not help you if you force flashing on a laptop because
  this is a really dumb idea.

So, I guess I should look at BiosDisk too.

openssl in 5.9-stable

[3ydft0+8enuoywmx5ae4]

Hello,

I am tracking 5.9-stable with cvs. Everything is fine.

The only
problem I see is that "openssl version" prints LibreSSL 2.3.4 instead of
2.3.6.
I rebuilt libcrypto, libssl and even openssl with no change.

According
to this file 
/usr/src/lib/libssl/src/crypto/opensslv.h
it should print 2.3.6
right ?

i thought my hostname was set during installation, but seems that it is

something new with 6.0 that requires to change the default hostname set
during installation ? or is it actually set during install ?

So you are talking about moving /usr from its own filesystem to /.
Careful with that. If you follow the auto disklabel defaults, / is
usually max 1GB and after a couple of upgrades /usr can easily get
too big for that (new libraries, new perl versions, etc). I would
rather take longer to do a dump/repartition/restore (or do some
other carving up/rejiggling of partitions) rather than leave a
timebomb for my future self, updates with too little space for
/usr are not very funny.

FOSS tools for flashing motherboard BIOS?

[Alan Corey]

I have an HP Pavilion DV2700 laptop with an old BIOS version I'd like
to update.  HP's official solution is to run something under the
dinosaur Windows Vista, which I was glad to wash my hands of about 7
years ago.

I opened up HP's exe file (rename to a zip and unzip), inside is a 1
meg file 30cdf2d.wph which I think is the payload.  It's a Phoenix
BIOS so it's set up to use Phoenix's WinPhlash utility.  I have no
operating system at all on the machine at present, it has no floppy
drive, doesn't boot from the CD/DVD.  I can boot from USB or the hard
drive only.  I can put in an old hard drive from another laptop and
boot it into OpenBSD.  Not booting from the CD is what I'm trying to
fix, a guy at HP support seems to think flashing the BIOS may help.
It's possible there are remnants of Windows "Secure Boot" around from
somebody trying to load Windows 7+ although since I can boot from USB
(a gparted ISO written to an SD card plugged into a USB reader) I
doubt it.

On the Arch Linux page at
https://wiki.archlinux.org/index.php/Flashing_BIOS_from_Linux there's
mention of a couple programs that might work: BiosDisk and Flashrom.
Anybody use either of those under OpenBSD?  I haven't tried chasing
down the source and trying to build them, I was a little surprised
they aren't in sysutils.  I don't see anything in there for flashing,
just looking in pbrowser.

Good to know. Looks like it is a Chromium problem then.

I have the same issue in both openbsd, win10 and mac os x yosemite. 

Thought it was my mouse though.

Synaptics/Chrome two-finger scrolling behaviour

[Henrik Friedrichsen]

Hey,

I'm not sure, but something seems to have changed two-finger-scrolling
on Synaptics touchpads in the latest snapshots.

My snapshot is from June 2nd. The following is what happens:

In Chromium, if I click somewhere and subsequently scroll the website
using two-finger-scrolling, it scrolls more units (e.g. to the
top/bottom of the page) and sometimes even in reverse. I can't quite
extract the pattern, yet.

Can anyone confirm this? Is this Xenocara or Chromium related?

If you would like the protection then I don't see any need to reinstall
btw.

I'm guessing (could be wrong) /usr isn't huge (so won't take ages) but
it's dead easy to gain the protection by using cp -Rp /usr to /home/usr

Then simply delete the /usr in disklabel and create a /usr
and /usr/local and copy back /home/usr to /usr and /home/usr/local
to /usr/local because cp is static and in the / root fs so you don't
even need to reboot, of course you would have to consider running
programs read requirements on those filesystems.

I agree.  Diff below should reduce the number of copies to 2.  In order
to remove the last copy somebody has to turn bridge_process() MP-safe
and merge it with bridge_input().  

Once this is done, bridge_input() can return "0" for multicast packets
and ether_input() will be call directly without the need for requeueing
the packet.

Re: Low brightness in text console

[Marcus MERIGHI]

To me this sounds like "Screen brightness is reset when changing from X
to console" thread on bugs@ [1].

[1] http://marc.info/?l=openbsd-bugs=146451346724515

Walter Alejandro Iglesias' workaround worked for me (thank you,
Walter!):

- run -current.
- use /etc/xorg.conf:

Section "Device"
Identifier  "Card0"
Driver  "intel"
Option  "AccelMethod"  "UXA"
EndSection

- PPPoE client (pppoe(4)) sends a PPPoE Discovery "initiation" frame, which is
  broadcast.

- PPPoE server (npppd(8)) receives 3 copies of it via bpf(4), then returns
  3 PPPoE Discovery "offer" frames.

- pppoe(4) receives 3 "offer" frames and gets confused ... somehow.

I don't know the internal of pppoe(4) yet.  pppoe(4) might have a bug, it
might be able to work even if it receives 3 replies at once, I don't know.

I don't think that npppd(8) receiving 3 copies of broadcast frames (via
bpf(4)) is an intentional design anyway.

What do you mean by "confuse pppoe(4)"?  I still don't understand what's
the link between pppoe(4) and bpf(4) in this case and why BPF matters
for a kernel driver.
