[Bug 1842020] Re: ceph patch as of 8/29 segfaults all bluestore osds

[Harry Coin]

FYI, in the eoan VM you used to duplicate the bug, try it again with the
processor set to 2 'Conroe' cpus. i440FX chipset, BIOS, kvm-spice
emulator.

Also, I tried compiling ceph nautilus from upstream, can't do it in eoan
without installing tox from bionic, and a couple other packages not in
eoan (e.g. libcui60 dependency upstream, eoan has ...63).  Had to add
these #pragmas which look memory related...

Title:
  ceph patch as of 8/29 segfaults all bluestore osds

Status in ceph package in Ubuntu:
  New

Bug description:
  The ceph patch on eoan distributed 8/29 crashes all bluestore OSD's
  and is unusable at least on some systems.  Failed on an old dual Xeon
  E5345 box.

  Easy test.  Run:

  /usr/bin/ceph-bluestore-tool

  On working systems it reports a help message.  On the latest eoan release distributed by canonical it
  turns in to an illegal instruction process kill, just after reading /proc/<...>/auxv

  looks like something to do with vsock issues.

  strace -k -y /usr/bin/ceph-bluestore-tool 
  is instructive.

  Notice valgrind against that program reports thousands of memory allocation issues.
  Reverting the system to the snapshot before the apt upgrade restores full operations.
