|

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.

|

|

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

|

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.
