Segmentation fault in ncurses

[Carsten Kunze]

Hello,

I am not on this mailing list and I am not able to debug the following issue.  
It is just for information since a segmentation fault may be an issue on a 
OpenBSD base system library.  The system I am using is very old (Oct. 2016) but 
ncurses likely does not have changed much since then:

OpenBSD 6.0-current (GENERIC) #2384: Fri Oct 14 00:06:17 MDT 2016

What I am trying to do is to display UTF-8 chars using wadd_wchnstr().  Then it 
crashes in lib_addstr.c:186 (I don't have the source).

If this is not relevant, just ignore the mail and sorry for the noise.

Program received signal SIGSEGV, Segmentation fault.

I even would be interested, but I need it for both OpenBSD *and* NetBSD.  A 
year ago I tried to update their pkgsrc version 1.2 to a current version, which 
did compile but not work.  My hope was to port the working OpenBSD package to 
NetBSD :)

If upstream would have any interest to give debug support on NetBSD, I'd like 
to update the OpenBSD package too.

Indeed an interesting tool.  Unfortunately I already have a special data sync 
tool (does not encrypt).  So I need a transparent encryption file system layer 
:)

This is for two reasons not of use for me: The Linux and the OpenBSD
systems are kilometers apart and the OpenBSD system is in a network
which allows no access from the internet.  So I have to transfer data
with a USB flash drive.

Also in most cases ssh does not support changing mtime of symlinks,
which is required for fast data synchronization (compare mtime
instead of readlink).  For this reason I even use USB when the two
systems are in the same network.

So it would really be great to have an up-to-date EncFS...

Thank you for this information and the test.
But it should be taken into account that this version is 6 years old, current 
release is 1.9.1.
(It would be great of course if the package maintainer would find the time to 
update the package to a somewhat newer version some day :)

Are you using EncFS on OpenBSD?  Which EncFS version?

I need the same and tried EncFS (cloned from GitHub) a year ago.  It compiles 
but doesn't work.  I asked upstream for support but they are not interested, 
they don't care for anything but Linux.  Which makes EncFS pointless--since 
there is LUKS--why should anyone use EncFS? (rhetorical question, don't answer)

If you get (a current version of) EncFS or any other portable encryption method 
to work, I would be very interested!

(But don't code it yourself, if you're not already an expert in this field.)

[OT] cwm: Keep window above all other windows

[Carsten Kunze]

Hi,

is there an *easy way* for put and always keep a window above all other windows 
(like "layer 0 " in fvwm)?  It did not find something (working) 
in the manpage.

I am not sure if it is really necessary to change the general groff settings 
just to use this settings for man pages.  I had the same problem long time ago. 
 Indeed there is a readme and it's the users fault to not read it.  But groff 
is expected to work out of the box, so I assume many others may not be aware of 
this readme.  Would it not be better to just patch the -man and -mdoc macros 
and not changing groff's settings for typesetting?

ncursesw header not found

[Carsten Kunze]

Hello,

in /usr/lib there seems to be the ncursesw library but I don't find a ncursesw 
header file (expected as something like .../ncursesw/curses.h).  I also don't 
find a curses package to install.  Is there ncursesw support for OpenBSD?  I 
found threads from 2010, but I'm not sure if they are still valid today.

--Carsten

ncurses and ncursesw share same header?

[Carsten Kunze]

curses, ncurses and ncursesw library seem to be hard links to one file.  So 
that means that with the -l option I decide which functions I use and always 
simply include ?  (At least this states the curses manpage.)

Inconsistency in utimes(2) manpage

[Carsten Kunze]

Hello,

the DESCRIPTION section of utimes(2) refers to "path" while
the SYNOPSIS section uses the term "file".  Maybe the term
"path" should be used instead of "file" in SYNOPSIS.

Not necessary that you tinker with a C programm, there is already
sed(1) which can change fstab and disklabel.

The current installer is just perfect.  For any additional task a
generic method would be that you write a shell script which
does your complete personal system configuration.

"cp -p" does not preserve the mtime of symlinks

[Carsten Kunze]

Hello,

"cp -p" seems to not preserve the modification time of symlinks.  This is not 
mentioned in the man page.  Other systems I tested (others BSDs and Linux) do 
preserve the mtime of symlinks with e.g. "cp -a".  The OpenBSD kernel also does 
support to set it with e.g. utimensat(2).

Is this intented?  If not--is it an known issue?

How to reproduce:

ln -s foo bar

... wait some time ...

cp -p bar blah

-> bar and blah have different mtimes.

I do care--I have a sync software (similar to rsync) which compares mtime and 
length.  lstat needs do be done anyway so there are just two integer compares 
instead of two readlink and strcmp.  This software "failes" after a "cp -RpP".  
If a patch is accepted I'd like to file a bug report with a patch.

the sysem doesn't boot since there is no boot block.

Only install58.fs itself did boot so there is only the dmesg if the standard 
installer image. That doesn't use softraid.

As suggested I wait for the next snapshot. If the issue with installboot is 
still there I'll send a dmesg.

I am surprised that OpenBSD had not cleaned it's own libs.  Or is libX11(.so)

In the BIOS setup of this laptop USB3 can only be switched on or
off.  It had been switched on.  When switching it to off the
problem does not occur anymore, the 5.7-snapshot is now running on
this laptop.  Thank you for your help!

If it would help I could apply patches from you to the kernel source
and do some tests.  But if you're not interessted in that it is ok
for me to live without USB3.

Re: Problem with cwm and tabbed

[Carsten Kunze]

There is a problem in OpenBSD 5.5 cwm with using pointers like

without testing cc-group for being NULL

This is (should be) fixed in current.  It leads to crashes of cwm (in 5.5) but 
may be not the cause for what happens on your system.

Re: sshfs does not seem to work correctly

[Carsten Kunze]

 Again I am guessing, but OpenBSD might disconnect if there is a 
 sufficient period of inactivity on the sshfs file system. Usb drives 
 disconnect if left long enough, for example. A running process, such as 
 an open terminal on the usb prevents this. It is a security feature.

There had only be seconds (at least one or two minutes) of inactivity.
Can this feature be disabled?  I'd like to use sshfs just as nfs so it
should not disconnect if possible.  A ssh session does not disconnect
too, I see no difference between ssh and sshfs regarding security here.

sshfs as non-root: fuse_mount: Permission denied

[Carsten Kunze]

Hello,

I am using OpenBSD as guest on a Linux host.
For accessing the host filesystems I've tried to use
sshfs(1) as a non-root user.  I've created a directory
and typed:

$ sshfs IP address:/ directory

The output is:

fuse_mount: Permission denied

But login via ssh(1) on that IP works.  sshfs from
other OSes to that host also work.  Why is it not
possible for a user to use sshfs?

It does work as root (I'd like to avoid that) but
then every file created on the host gets owner
root.  (NetBSD mount_psshfs also seems to
require root but there the file owner is set as
expected.)

--Carsten

Re: sshfs as non-root: fuse_mount: Permission denied

[Carsten Kunze]

 This is probably why...
 
 % ls -lao /dev/fuse0
 crw---  1 root  wheel  -  92,   0 Jul  5 05:38 /dev/fuse0

Not completely. With 660 or 666 permissions the response now is:

Operation not permitted

Re: sshfs as non-root: fuse_mount: Permission d enied

[Carsten Kunze]

 I may be completely off the mark here but I believe that in OpenBSD all 
 mount points _must be owned by root. So you have to pass options for uid 
 and gid with the mount command.

I had expected that that works. But that is not really comfortable and kind of
faking and overriding the uid.

Ok, if that is required, then I need to do this.  But it should not be a 
security
issue to use sshfs on a directory owned by a user.  So I do not really
understand this requirement.

Re: sshfs as non-root: fuse_mount: Permission d enied

[Carsten Kunze]

 I'll regroup. I don't have access to an OpenBSD system at the moment 
 but I'm trying to recall the readme and man page for ntfs-3g which also 
 uses fuse.
 
 Using fuse which may lead to a privilege escalation, I think, ... and 
 that is why ntfs-3g has to be run as root and pass uid and gid options. 
 I'm guessing that sshfs will be similar.

Fabian suggested to set kern.usermount to a non-zero value, now it works
as expected.  Maybe this could help ntfs-3g also, I don't know.
(Setting uid/gid is not a nice solution.  But if it's necessary ...)

Cheers, Carsten

sshfs does not seem to work correctly

[Carsten Kunze]

I use sshfs to synchronize a filesystem of 15 GB between two machines.
Read access seems to be ok but on writing the mount point
does not seem to work anymore.  Error message of cp(1) is

No such file or directory

ls(1) to the mount point gives the same message.
(Nothing in /var/log/messages)

Is it a known problem for sshfs that the mount point may
disappear?  (OpenBSD 5.5 amd64)

Slow display of embedded EPS with gv

[Carsten Kunze]

Hello,

when I include a large EPS file into a PostScript file using the colorimage 
command (actually done bei groff macro .PSPIC) and view this PS file with the 
gv viewer it takes very long until the image is displayed. For example it takes 
40 seconds until a 2 MB image is displayed on a rather fast DELL E6540. On a 
years old Linux PC there is no noticeable delay. With many images in a document 
gv is unuseable. (So I convert the PS to PDF, then it's ok.)

What may be the reason?

--Carsten

Slow display of embedded EPS with gv

[Carsten Kunze]

I tried to reproduce this with the EPS file an gv alone.
That did not work, i.e. it opens without delay.
Unfortunately this now becomes groff dependent.
But anyway it's also OpenBSD specific.
I tried with http://www.openbsd.org/images/poster31.jpg:

jpegtopnm poster31.jpg  poster31.pnm
pnmtops poster31.pnm  poster31.ps
gv poster31.ps # - opens at once

File t.tr:
.PSPIC poster31.ps

troff -Tps t.tr|grops t.ps
gv t.ps # - opens at once

troff -Tps -dpaper=a4 t.tr|grops -pa4 t.ps
gv t.ps # - opens very slow (15 seconds)

Embedded in a real document it took about 40 seconds for
a picture of that size. As mentioned in the previous mail
there is no delay on e.g. Linux.

 But I think you agree with the general tone of this?

In some aspects OpenBSD is *very* slow. After booting the X Windows System 
appears without delay but then it takes 23 seconds until xdm screen opens (on a 
fast Dell E6540). Also after changing from X to a virtual console and back (in 
the test case xlock was active) X appears without delay but it takes 10 seconds 
until the keyboard works.

There is no delay in this cases on NetBSD or Linux even on my very old Dell 
D830 and even with a nvidia card. What can be the reason for this large delays?

Re: AR9462 WLAN support

[Carsten Kunze]

Hello,

 Hi. I've just realized that my laptop has the same chip. Do you have any 
 updates? Maybe I can help somehow? Thanks

I've spended a lot of time but some day a gave up. Now I have a Dell E6540 
where really everything works (sincere thanx to all developers!), so I think I 
leave the other laptop unused (it has another problem--with the current gfx 
driver the C70 GPU gets near to 100 degree celsius).

There is a working driver for FreeBSD. Initially I thought I could port it, but 
it is very FreeBSD dependent. Then I tried to extend the athn by looking at the 
FreeBSD code. Maybe the better way--since if you want to distribute it it has 
to have OpenBSD quality anyway. But if you look at the amount of code of this 
driver you see that it's a lot of work to do.

There is also a driver for Linux, but one could assume that there would be more 
work to do than using the FreeBSD code.

With my current time budget I can do testing and small code changes but real 
development I can't do in the near future, unfortunately.

Regards,
Carsten

are there any plans to support the Atheros AR9462 WLAN IC (aka AR5B22, aka

If not, might it be possible to port code from the ath9k driver (Linux) or 
would that not be a feasible way?

Re: AR9462 WLAN support

[carsten . kunze]

 Are you asking because you're interested in hacking on this yourself?

If there would already be some work in progress I'd like to use this one day 
instead of hacking myself. If not I'd intend to work on it. Not really short 
term though.

 It has also been suggested to port FreeBSD's ath driver to OpenBSD.
 I don't believe that is less work than extending the existing athn
 driver, though.

I'd prefer to extend the athn driver, I'd investigate at first in that.

Thank you for your extensive information.
