From 4149df9005f2cdd2ecf70058dfe7d72f48c3a68c Mon Sep 17 00:00:00 2001
From: John Ogness <john.ogness@linutronix.de>
Date: Wed, 25 Nov 2020 23:26:59 +0106
Subject: [PATCH] printk: add support for lockless ringbuffer
Linux 5.10 moved to a new lockless ringbuffer. The new ringbuffer
is structured completely different to the previous iterations.
Add support for retrieving the ringbuffer using vmcoreinfo. The
new ringbuffer is detected based on the availability of the
"prb" symbol.

Indeed, "unsigned long" constants are 32-bit on 32-bit platforms, and
64-bit on 64-bit platforms.
Fix this by using a "ULL" suffix instead.

Subject: [PATCH] [PATCH] Show write byte size in report messages
Show write byte size in report messages. This value can be different
from the size of the actual file because of some holes on dumpfile
data structure.
$ makedumpfile --show-stats -l -d 1 vmcore dump.ld1
...
Total pages : 0x0000000000080000
Write bytes : 377686445
...
# ls -l dump.ld1
-rw------- 1 root root 377691573 Feb 4 16:28 dump.ld1
Note that this value should not be used with /proc/kcore to determine
how much disk space is needed for crash dump, because the real memory
usage when a crash occurs can vary widely.

Subject: [PATCH] check for invalid physical address of /proc/kcore
when finding max_paddr
Kernel commit 464920104bf7adac12722035bfefb3d772eb04d8 ("/proc/kcore:
update physical address for kcore ram and text") sets an invalid paddr
(0xffffffffffffffff = -1) for PT_LOAD segments of not direct mapped
regions:
$ readelf -l /proc/kcore
...
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
NOTE 0x0000000000000120 0x0000000000000000 0x0000000000000000
0x0000000000002320 0x0000000000000000 0x0
LOAD 0x1000000000010000 0xd000000000000000 0xffffffffffffffff
^^^^^^^^^^^^^^^^^^
0x0001f80000000000 0x0001f80000000000 RWE 0x10000
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.

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.
