[Bug 1483615] Re: usbhid-ups driver segfaults on discovery of UPS
Hi Charles, Thanks. I think that solved it: root@barnbox:~# tail -n 7 /etc/nut/ups.conf && /lib/nut/usbhid-ups -u nut -a apc [apc] driver = usbhid-ups port = auto desc = "APC Back-UPS" #bus="001" #vendor="051d" Network UPS Tools - Generic HID driver 0.38 (2.7.1) USB communication driver 0.32 Using subdriver: APC HID 0.95 root@barnbox:~# FWIW when I report this original bug I did reboot, update, reboot and re-test just to be sure it still existed... I really *did* try to narrow it down! Thanks anyway... now to go back to the UPS config as planned! -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nut in Ubuntu. https://bugs.launchpad.net/bugs/1483615 Title: usbhid-ups driver segfaults on discovery of UPS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1483615/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1483615] Re: usbhid-ups driver segfaults on discovery of UPS
Since you only have one UPS, I would recommend removing the extra "-x" options (this prevents problems down the road if a new kernel assigns a different bus number). I believe the regex matcher is case-sensitive, so the "051D" does not match. Interestingly enough, we did have another recent unreproducible report of an APC-related segfault that cleared up after a reboot: https://github.com/networkupstools/nut/issues/252 but it would be interesting to find out why the string descriptors are sometimes not available. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nut in Ubuntu. https://bugs.launchpad.net/bugs/1483615 Title: usbhid-ups driver segfaults on discovery of UPS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1483615/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Hi Charles, I can see your thinking, but no, this isn't a VM, nor is the kernel I'm using a Hypervisor - it's a plain old machine: root@barnbox:~# grep -i hyper /proc/cpuinfo root@barnbox:~# I updated the machine with apt-get (again) and I also updated the machine's BIOS.

[Bug 1483615] Re: usbhid-ups driver segfaults on discovery of UPS
@davis65536: I think we might have a lead on this. Are you running in a VM? https://github.com/networkupstools/nut/issues/258 The APC portion of usbhid-ups expects that if it can open the device, it can read the string descriptors. Your system is printing "unknown" for the Manufacturer, Product and Serial Number lines for your UPS. IMHO this is also a bug elsewhere (libusb, kernel or hypervisor?) since the Product string is the easiest way to distinguish between the various 051d:0002 USB devices, though I agree that the driver should be more robust. Can you see the APC vendor string if you run "lsusb -vvv -d051d:" as root? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nut in Ubuntu. https://bugs.launchpad.net/bugs/1483615 Title: usbhid-ups driver segfaults on discovery of UPS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1483615/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
