   An update that solves two vulnerabilities, contains one
   feature and has four fixes is now available.

Description:

   This update for multipath-tools fixes the following issues:

   - CVE-2022-41973: Fixed a symlink attack in multipathd. (bsc#1202739)
   - CVE-2022-41974: Fixed an authorization bypass issue in multipathd.
     (bsc#1202739)

   - multipathd: add "force_reconfigure" option (bsc#1189551) The command
     "multipathd -kreconfigure" changes behavior: instead
       of reloading every map, it checks map configuration and reloads
       only modified maps. This speeds up the reconfigure operation
        substantially. The old behavior can be reinstated by setting
        "force_reconfigure yes" in multipath.conf (not recommended). Note:
        "force_reconfigure yes" is not supported in SLE15-SP4 and beyond,
        which provide the command "multipathd -k'reconfigure all'"

   - multipathd: avoid stalled clients during reconfigure (bsc#1189551)
   - multipathd: handle client disconnect correctly (bsc#1189551)
   - Avoid linking to libreadline to avoid licensing issue (bsc#1202616)
   - multipathd: don't switch to DAEMON_IDLE during startup (bsc#1197570)
   - multipathd: disallow changing to/from fpin marginal paths on reconfig
   - multipathd handle fpin events (bsc#1195506,jsc#PED-1448)
   - multipath: fix exit status of multipath -T (bsc#1191900)
