From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski Date: Wed, 24 Mar 2021 14:15:02 -0500 Subject: [PATCH] libmultipath: avoid infinite loop with bad vpd page 83 identifier If a device with a scsi name identifier has an unknown prefix, parse_vpd_pg83() needs to advance to the next identifier, instead of simply trying the same one again in an infinite loop.
