A followup to myself

Looking at rk_gpio.c it appears that interrupts are not supported for
the Rock64 systems in the NetBSD driver for the Rockchip.  However, the
technical reference manual for the RK3328 and RK3399 suggest that those
two variants support interrupts on the GPIO pins, so it might just be a
matter of software.  The rest of the variants might also have support I
just didn't look.  I don't have this particular SOC system, so will be
of little help, but a quick read of the TRM suggests that it isn't
largely different from how the Broadcom (RPI family) GPIO interrupts
work and it wasn't that hard to add GPIO interrupt support for Broadcom
when I did that years ago.

So for right now, it looks like you may be out of luck for ntpd PPS use
on a Rock64 system (except for the USB DCD support which would work if
the GPS chip supports it).

Followup for the archives.

There are two problems that combine for hard-to-debug bad behavior.

1) devname(3)

devname(3) converts a device major/minor to a pathname.  sudo uses this.
However, it uses /var/run/dev.cdb, which is created by dev_mkdb(8) which
runs at boot.

So if you boot your system with /dev/ttyp*, mount ptyfs, rm /dev/ttyp*,
and log out and back in, you will still get e.g. /dev/ttyp5 from
devname.  (I saw this in the sudo logs.)


2) sudo bugs

sudo's default is 'tty'.  It gets the major/minor.  But it doesn't just
store that in the timestamp file.  It calls devname, and if it can't
stat the result, *silently*, even with respeect to debugging statements,
switches to ppid mode.  If it can stat, it stores the dev_t in the file.

See plugins/sudoers/timestamp.c, line 415, where it checks that stat
succeeds on the path.

The bad bug is that failure to stat a path that should be valid should
be fatal, not a silent flip to ppid.  The lesser bug is that if the
thing that matters is the dev_t, it should just use that.



Once realizing, re-running dev_mkdb caused devname to return /dev/pts/5
instead, and things work as I would expect.

I failed to mention this before, and I don't think that the gpiopps(4)
man page mentions this, but you need a device that supports GPIO
interrupts to use gpiopps(4).  Not all of the SOC systems support that.

The message you are getting very much implies that interrupts are not
supported in the configuration you are trying to use (which wasn't
exactly metioned).

There are several possible situations...  for example, the RPI family
supports GPIO interrupts on the positive and negative edge of the pulse
and at the same time (gpiosim(4) does too now, but that is a GPIO
simulator).  It may be that your device only supports it on one edge or
the other or not at all.  The ntpd PPS driver, I seem to remember,
supports using just one edge and I think I remember that it could be
either one (or it use both edges).  You can configure gpiopps(4) to do
any of those cases.  You can also try using gpioirq(4) and see if
interrupts work at all, if you can't find documentation anywhere for
your device.  If you can get interrupts on one edge working I think you
win with ntpd, otherwise that device can't be used.

This works here (as far as lfs works), but the error message is
rare. One possibility is that the SCSI driver reports an offline
unit. Can you tell what the iSCSI server is ?

The address parser looks broken. For some reason the first character is skipped 
when it tries to identify IPv6, I was successful with

iscsictl add_send_target -a 'x[ipv6-address]'

Thanks for the detailed information and discussion.

I built a kernel for my Rock64 on its bigger sibling RockPro64 (has a PCIe
SSD card) -- sorry, okay, that was me just saying how much I enjoy these 2
devices! Anyway...I ran into a problem initializing gpiopps. Here is the

Here's what I added to evbarm/conf/GENERIC64:

This is for physical pin 7 which per pine64 wiki is GPIO1_D4. So gpio1 and
D=3, so 3*8 + 4 = port 28.

I tried also modifying the RockPro64 kernel -- similar issue.

Any idea what am I doing wrong?

iscsid - lfs and ipv6 issues

2023-11-17 Thread Ede Wolf

Hello,

I am having two issues with iscsid/iscsictl. First, it seems, I cannot 
mount an lfs formatted iscsi lun, no matter wether this drive is 
gpt/wedge or plain disklabelled:


# mount -t lfs /dev/dk0 /import/
mount_lfs: /dev/dk0 on /import: Operation not supported by device


Secondly, I am unable to determine the syntax to correctly specfiy an 
ipv6 address to iscsictl.
I've tried the plain address, in square brackets, in double quotes, 
always getting an error:



scsictl: add_send_target: Invalid option at or near '-a': Bad address 
format: Extra character(s) ':'


That is on 10 RC1, but I have never tried this before with earlier 
versions.


Am I missing something or are there any knows issues I should be aware of?

Thanks for any insight

Ede

Interesting and a good point.  I just ran sudo in an xterm without tmux
and the entry in the cache file is still type 3.  But great to take tmux
out of the picture; I should have tried that before posting.

recent strange sudo behavior, probably due to /dev/pts

2023-11-17 Thread Greg Troxel
My system is netbsd-10.  It was installed around 2003 and has been
updated since then, both to each NetBSD stable branch, and to new disks
usually via dump/restore and sometimes rsync.  Other than the problem I
am describing in this message, occasional hangs that I blame on ZFS, and
X display glitches, it is working well.

I have logged in to ttyE0, and ran "xinit .xsession" which starts xfce4
and I am in an xterm with tmux.

I had recently noticed that my system did not have /dev/pts, so I grabbed
the line from /etc/fstab on a more recenntly-installed system.  I then
removed the /dev/ttyp* type entries.  This messed up tmux but logging
out and starting fresh was ok, and this was not surprising.  Now the
system is apparently ok execpt for sudo/pkgsrc.

I have for a long time had in mk.conf:

  SU_CMD=sudo /bin/sh -c

and "make replace" has invoked sudo, with sudo respecting the
don't-ask-for-password timer as documented.  Recently this stopped
working.

After a lot of investigating including writing a quick read/printf
program to examine the sudo timestamp files, the problem appears to be
that the timestamp records are "TS_PPID" rather than "TS_TTY".  The
parent is something deep in make, and thus different every time.  So
this is not really a pkgsrc issue.

I have added:
  Defaults timestamp_type=tty




Has anyone else seen sudo refusing to use tty as a timestamp type?


sudoers(5) excerpt:

 timestamp_typesudoers uses per-user time stamp files for credential
   caching.  The timestamp_type option can be used to
   specify the type of time stamp record used.  It has the
   following possible values:

   global  A single time stamp record is used for all of a
   user's login sessions, regardless of the
   terminal or parent process ID.  An additional
   record is used to serialize password prompts
   when sudo is used multiple times in a pipeline,
   but this does not affect authentication.

   ppidA single time stamp record is used for all
   processes with the same parent process ID
   (usually the shell).  Commands run from the
   same shell (or other common parent process)
   will not require a password for
   timestamp_timeout minutes (5 by default).
   Commands run via sudo with a different parent
   process ID, for example from a shell script,
   will be authenticated separately.

   tty One time stamp record is used for each
   terminal, which means that a user's login
   sessions are authenticated separately.  If no
   terminal is present, the behavior is the same
   as ppid.  Commands run from the same terminal
   will not require a password for
   timestamp_timeout minutes (5 by default).

   kernel  The time stamp is stored in the kernel as an
   attribute of the terminal device.  If no
   terminal is present, the behavior is the same
   as ppid.  Negative timestamp_timeout values are
   not supported and positive values are limited
   to a maximum of 60 minutes.  This is currently
   only supported on OpenBSD.

   The default value is tty.

   This setting is only supported by version 1.8.21 or
   higher.

There are two things that you could verify:

1) That the legacy drm kernel module is also loaded;
2) Since the drm or drmkms use the filesystem (ioctl), the /dev/drm*
also exist.

You can have an overview of drm and drm-kms with the (not included in
the release) manual pages, in the netbsd-xsrc:

./external/mit/libdrm/dist/man/drm.7.rst
./external/mit/libdrm/dist/man/drm-kms.7.rst

Note: I have to finish a modification to userconf and config(1). But
after that I will give a look to legacy i915drm since I have an
integrated Intel GPU too (but I use a discrete radeon, that works in
10.0).
