+   or NFS protocol, the corresponding network interface '<interface-name>' is
+   renamed to 'kdump-<interface-name>', if it is generic (like *eth# or net#).
+   It happens because vmcore capture scripts in the initial RAM disk (initrd)
+   add the 'kdump-' prefix to the network interface name to secure persistent
+   naming. And as capture kernel and production kernel use the same initrd in
+   case of FADump, the interface name is changed for the production kernel too.
+   This is likely to impact network configuration setup for production kernel.
+   So, it is recommended to use a non-generic name for a network interface,
+   before setting up FADump to capture vmcore to a remote dump target based on
+   that network interface, to avoid running into network configuration issues.

+Note that this value should not be used with /proc/kcore to determine

+makedumpfile uses max_paddr to calculate the number of sections for
+sparse memory model thus wrong number is obtained based on max_paddr
+(-1).  This error could lead to the failure of copying /proc/kcore
+for RHEL-8.5 on ppc64le machine [1]:
+
+  $ makedumpfile /proc/kcore vmcore1
+  get_mem_section: Could not validate mem_section.
+  get_mm_sparsemem: Can't get the address of mem_section.
+
+  makedumpfile Failed.
+
+Let's check if the phys_start of the segment is a valid physical
+address to fix this problem.

+From: Tao Liu <ltao@redhat.com>
+Date: Fri, 18 Jun 2021 18:28:04 +0800
+Subject: [PATCH] check for invalid physical address of /proc/kcore
+ when making ELF dumpfile
+
+Previously when executing makedumpfile with -E option against
+/proc/kcore, makedumpfile will fail:
+
+  # makedumpfile -E -d 31 /proc/kcore kcore.dump
+  ...
+  write_elf_load_segment: Can't convert physaddr(ffffffffffffffff) to an offset.
+
+  makedumpfile Failed.
+
+It's because /proc/kcore contains PT_LOAD program headers which have
+physaddr (0xffffffffffffffff).  With -E option, makedumpfile will
+try to convert the physaddr to an offset and fails.
+
+Skip the PT_LOAD program headers which have such physaddr.
