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)
