An update that solves two vulnerabilities, contains one feature and has four security fixes can now be installed.

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)
