Description:

This update for xen fixes the following issues:

Security issue fixed:

  • CVE-2021-28689: Fixed some x86 speculative vulnerabilities with bare (non-shim) 32-bit PV guests (XSA-370) (bsc#1185104)

  • Make sure xencommons is in a format as expected by fillup. (bsc#1185682)

Each comment needs to be followed by an enabled key. Otherwise fillup will remove manually enabled key=value pairs, along with everything that looks like a stale comment, during next pkg update

  • A recent systemd update caused a regression in xenstored.service systemd now fails to track units that use systemd-notify (bsc#1183790)
  • Added a delay between the call to systemd-notify and the final exit of the wrapper script (bsc#1185021, bsc#1185196)
