Oops.

The upstream patch (which was made after upstream release 3.2) back- ported to upstream 3.1 release (Ubuntu 18.04 contains dmidecode 3.1); it should presumably apply cleanly to Ubuntu's dmidecode-3.1 source. ** Patch added: "0001-dmidecode-Only-scan-dev-mem-for-entry-point-on-x86.patch" https://bugs.launchpad.net/ubuntu/+source/dmidecode/+bug/1821632/+attachment/5306518/+files/0001-dmidecode-Only-scan-dev-mem-for-entry-point-on-x86.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821632 Title: dmidecode causing system crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmidecode/+bug/1821632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1821632] Re: dmidecode causing system crash
> Reading illegal memory should not crash the system I think this depends on what the memory is. I agree 100% for any application-level memory (stuff from regular APIs like sbrk() or mmap() etc.). In this case, the application opens /dev/mem, which allows it to access arbitrary physical memory without restriction. It assumes that a certain physical memory region can be accessed (the DMI region) and does so. The HW triggers an SError in this case since no device exists at that location in memory, since this platform doesn't support DMI. This is correct HW response to the request. The solution is to prevent SW from accessing this location. This issue happens identically if you were to use an upstream kernel (which does support the HW), or the Ubuntu kernel (assuming it supports this HW model). Whether this SW access prevention is implemented in the kernel or the application may be open for debate. I believe the definition of the /dev/mem device is such that it does not intend to filter addresses to prevent applications from accessing invalid HW. As such, I believe it's up to the application to fix the issue; it should determine whether the platform supports DMI before explicitly using low-level primitives (/dev/mem) to attempt to access it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821632 Title: dmidecode causing system crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmidecode/+bug/1821632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This problem seems to occur with kernels provided by NVIDIA for their Jetson T2 and Xavier boards. I got it when programs like cfengine or ocs-inventory-agent periodically called dmidecode. This crashed a Xavier board. See also https://devtalk.nvidia.com/default/topic/1003952/jetson-tx2 /dmidecode-crashes-r27-1-on-tx2/. Although NVIDIA blames the application (dmidecode), I consider this a kernel bug. Reading illegal memory should not crash the system, but simply fail with an error status. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821632 Title: dmidecode causing system crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmidecode/+bug/1821632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
