• QEMU s390x bug fix

    From Nelson H. F. Beebe@21:1/5 to All on Thu Jul 30 02:10:01 2020
    I post this note to draw attention to a bug that I reported six weeks
    ago in QEMU's emulation of IBM System/390 hardware:

    QEMU S/390x sqxbr (128-bit IEEE 754 square root) crashes qemu-system-s390x
    https://bugs.launchpad.net/qemu/+bug/1883984

    A 2-character patch was quickly found by QEMU developers, but has been disappointingly slow to make its way into various Linux distributions.

    This bug can be triggered with a one-line user program that then
    crashes the O/S, and the virtual machine, and that can also corrupt
    assorted files on the systme, and write garbage into system logs.
    Thus, I view it as a severe one whose repair should be quickly pushed
    into O/S distributions.
