http://bugzilla.opensuse.org/show_bug.cgi?id=1155510 Bug ID: 1155510 Summary: iscsid service failed - stack smashing detected - when trying to connect client to target Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Linux Status: NEW Severity: Major Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: registrations@thestonefamily.us QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I just installed the latest Tumbleweed (20191027) am unable to connect to a target. Yast locks up while configuring a new connection (Network Services -> iSCSI Initiator -> Discovered Targets -> Connect). I am able to discover the targets and then after I specify the connection information (startup - automatic, authentication by targets) and and hit next (F10) yast locks up. In the log files I can see a bunch of error messages from the iscisd service (detailed a little bit later). The iSCSI target is on a QNAP NAS on my local LAN (and I have an OpenSuse Leap instance connected to another target on the same NAS). I have tried this both on a clean install and in a virtual machine. Via journalctrl I see the following messages: Oct 30 10:38:54 tumbleweed-vm systemd[1]: Listening on Open-iSCSI iscsid Socket. Oct 30 10:41:53 tumbleweed-vm iscsid[1146]: *** stack smashing detected ***: <unknown> terminated Oct 30 10:41:53 tumbleweed-vm systemd[1]: iscsid.service: Main process exited, code=dumped, status=6/ABRT Oct 30 10:41:53 tumbleweed-vm systemd[1]: iscsid.service: Failed with result 'core-dump'.

sudo systemctl start iscsid Job for iscsid.service failed because a fatal signal was delivered causing the control process to dump core. See "systemctl status iscsid.service" and "journalctl -xe" for details.

I had a previous version of Tumbleweed that was connected to this target and ran into this problem after reinstalling Tumbleweed the other day. I can easily reproduce this in a VM that I created earlier today - so, if there is any additional logging needed, etc - just let me know :-) Any help would be appreciated.
