SIGSEGV in _nss_dns_gethostbyname2_r() browsing Samba printers, i386 only

Can you confirm this bug for latest version published in Jaunty?

system-config-printer-gnome 1.1.3+git20090218-0ubuntu6

Bug confirmed after upgrading this morning.

I was unable to recreate this bug using system-config-printer version 1.1.3+git20090218-0ubuntu18 on Jaunty Jackalope.

Fixed in Jaunty

I have Jaunty with all updates, but still have this bug....

Reopening as this is not fixed in Jaunty, multiple reports show.

According to duplicate bug 368273 this seems to be hitting i386 but not amd64, which might be the reason why Brian failed to reproduce it.

A workaround to be able to create printers (using IP address) is described in https://bugs.launchpad.net/ubuntu/+source/samba/+bug/368273/comments/10

Adding samba task since the crash is probably related to libsmbclient.

A nearly identical crash in _nss_mdns4_minimal_gethostbyname2_r is tracked in bug 359088. I suspect it's coming from the same bug.

Hm, I am struggling with the root cause of this. It is a Jaunty-specific issue, but the libsmbclient code shown in the trace didn't really change since Intrepid... However the glibc code (where the SIGSEGV ultimately occurs) did change. In particular sysdeps/posix/getaddrinfo.c. So maybe it's a side-effect of glibc bug 374674. The stack clearly passes through code from that now-useless Ubuntu-specific patch. I'll try to narrow it some more.

Unfortunately I couldn't reproduce the issue. I can set up Samba-shared printers on 9.04 / i386 without a crash. Maybe it's linked to Windows XP shared printers...

@Ed Comer or other reproducers:
If the issue is linked to the glibc bug, then it should be fixed in Karmic (the glibc patch was dropped there, no change in samba). Could you take Alpha1/i386 for a test run on your environment and let us know if the crash is gone ? If it does, I'll push the issue into glibc lands...

Hm, that wouldn't work, Karmic glibc still has patches/any/local-ipv6-lookup.diff so the test wouldn't prove anything. Please ignore what I just said.

I switched to the amd64 version of 9.04 and can no longer reproduce the bug since it isn't resident in the 64-bit version.

You received this bug notification because you are a direct subscriber
of a duplicate bug.

9.04 seems to have a problem and cannot print to winxp although I could with 8.4 . I can see all shared folders on winxp box but cannot see or find the printer attached to winxp box. Also the GUI for selecting a printer d0es not show "Samba connected printers" and I think it was there for 8.4 . I have had no useful ideas , seems to affect others.

Read:
http://ubuntuforums.org/showthread.php?t=1140448

The workaround does work.

Also, remember that SAMBA does not enable you to see Windows shares, that is what smbclient does. SAMBA is what lets Windows see Linux shares. Nonetheless, if you can see your Windows system's shares, then this workaround will fix the printer issue.

Motorman:
Are you positive that the printer on Windows is set to SHARE? If so, the printer shown in Windows' "Printers and Faxes" dialog should have a little hand on it (see attachment).

Yes the printer does have the "hand" and it was working fine under 8.04.. I
also do not have ability to do the workaround as my GUI does not show
"windows printer via Samba"under networked printers in the
system>admin>printing GUI menu.. ( why not??)
The person who did the workaround used the 64 bit 9.04 version and I am on
the 32 bit. Apparently the 64 bit does NOT have this bug as stated in the
forums.
Thanks for your kind thoughts and ideas but I am almost at the point of
buying a wireless accessible printer.. as I spent too much time already on
this.
I have one idea that I will try and to make the windows connected printer
not shared and then reboot and make it shared.. this could well be a windows
problem.. it would not suprise me!!
Thanks again

motorman: I was the creator of the workaround on a 32-bit system. I have since loaded a 64-bit system and, yes, it doesn't have this bug.

While it could be a Windows problem, possibly something isn't right with your SAMBA setup. Even is SAMBA isn't installed, smbclient utilizes the samba.conf file. I recommend that you read the excellent posting at:
http://tinyurl.com/nvsnoj

Ed, Thanks , I did some checking and I have two other winxp systems each
with printers attached, both can print on the other machine.
I tried to follow someone who wrote about modifying smb.conf and messed it
up so badly that I downloaded a default version from ubuntu 8.4 as can't
find a default version for 9.04. ( Iknow i should have made a copy first
before messing with it... sometimes I get too impatient )
Thanks for lead to the Samba set up I'll try and follow it carefully. I'll
report results,
Can I put on a 64 bit version if my system is 32 bit and a fw years old?
Thanks again.

To anyone that can reproduce this precise bug on a Jaunty test system:
Could you test and install glibc 2.9-4ubuntu6.1~ppa1 from my PPA at https://launchpad.net/~ttx/+archive/ppa and let me know if it fixes the problem or not. You should upgrade the libc6 binary package (which should pull the libc6-i686 or libc6-amd64 and libc6-dev packages). Please reboot before testing to make sure you fully test the right glibc.

I do not know how to do a test without reloading 9.04 . I do not have a
problem now and can print fine with 9.04 and a 32 bit O/S. If you can give
me a safe way to check out your idea I will try but I am very concerned that
I will be back in the mess again. It took me nearly 35 hours to have a
system that does everything it should and did on U 8.1.
Whatever I did it seems that all I needed to do was to load smbclient as
this was missing when I did the update form 8.1 to 9.04.
Could it be that simple!!

Far better one rose to the living than sumptuous wreaths to the
dead...Rachael Doctors

I am running Ubuntu 9.04 AMD64 with the latest patches and in Administration-Printing-New Printer-Network Printer I do not have any "Windows printer via SAMBA" option. The printer I am trying to print is valid and working (several other windows boxes print to it). smbclient -L <server> also shows correctly the shared printer.

Any ideas ?

I also run Ubuntu 9.04 AMD64 and have no problem at all, although it was present on the same machine when I ran the i386 version. This problem does not seem to exist in 64-bit Ubuntu. I suspect that you have a setup problem. I recommend that you read the post at the following link:

http://tinyurl.com/lpg2uk

just install smbclient .. you can do this in the command window, not
abslotuley sure but I think it is something like:
sudo apt-get install smbclient
Make sure that samba is not loaded when you do this. you need to do a stop
on samba if it is running.
This worked great fro me under Ubuntu 9.04 and solved my inability to print
on a win box printer in my LAN.

The smbclient binary was already present, as I mentioned in my previous message (smbclient -L <server> shows the correct info). However, after some more digging it seems I had samba4 installed that that appeared to be the problem.

I have downgraded to samba 3 and now everything works ok, I can add a SAMBA printer and printing works.

I forgot to mention but I had the same problem, I put Samba4 on thinking
that would help but it did not, and I then did a complete removal of all the
samba4 and any other samba I could and then did a reinstall of samba via
synaptic. However this did NOT install the smbclient. I am puzzled by this
as it is part of the samba install..It could have been that samba was
running when I tried to do the synaptic reinstall. If this makes no sense to
anyone then perhaps someone can tell me why I had the " use samba
printers...." showing in the printing GUI with 8.01 then it dissapeared
when I upgraded to 9.04.

Smbclient is part of the standard Ubuntu or Xubuntu installation. If it wasn't present you must have done something to cause its removal. While SAMBA is not preinstalled as part of the standard Ubuntu or Xubuntu installation, it is not necessary to browse Windows shares. Samba enables Linux shares to be seen by Windows.

Thanks but samba was installed when did my 8.01 install from the original
Ubuntu download...I am Ok now and I cannot seem to help anyone else, thanks
for all your help.. all of you. Also smbclient maked it possible to print on
my win box attached printer.
I am sure you are right, and I know next to nothing about Ubuntu , in my
next life I will try harder to learn more software but until then .. thank
you Ubuntu!!

Far better one rose to the living than sumptuous wreaths to the
dead...Rachael Doctors

I was not able to see the printers. I updated the system with third party canonical repositories on, and the bug disappeared.

@filozofio:
What do you mean by "third-party canonical repositories" ? Did you enable my PPA as suggested in comment 20 ? In doubt please post the output of "dpkg- l libc6". Thanks !

glibc was updated in karmic removing the problematic patch. Would be good to confirm that the problem is gone on karmic now.

This is believed to be fixed in karmic by the bug 374674 fix. Please reopen if you can still reproduce it on current karmic.

Not a system-config-printer bug
