Subject: [PATCH] Increase SECTION_MAP_LAST_BIT to 5
|
|
||||||
|
|
||||||
* Required for kernel 5.12
|
|
||||||
|
|
||||||
Kernel commit 1f90a3477df3 ("mm: teach pfn_to_online_page() about
|
|
||||||
ZONE_DEVICE section collisions") added a section flag
|
|
||||||
(SECTION_TAINT_ZONE_DEVICE) and causes makedumpfile an error on
|
|
||||||
some machines like this:
|
|
||||||
|
|
||||||
__vtop4_x86_64: Can't get a valid pmd_pte.
|
|
||||||
readmem: Can't convert a virtual address(ffffe2bdc2000000) to physical address.
|
|
||||||
readmem: type_addr: 0, addr:ffffe2bdc2000000, size:32768
|
|
||||||
__exclude_unnecessary_pages: Can't read the buffer of struct page.
|
|
||||||
create_2nd_bitmap: Can't exclude unnecessary pages.
|
|
||||||
|
|
||||||
Increase SECTION_MAP_LAST_BIT to 5 to fix this. The bit had not
|
|
||||||
been used until the change, so we can just increase the value.

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.

Supported Kdump Targets
|
||||||
|
|
||||||
|
This document try to list all supported kdump targets, and those supported
|
||||||
|
or unknown/tech-preview targets, this can help users to decide whether a dump
|
||||||
|
solution is available.
|
||||||
|
|
||||||
|
Dump Target support status
|
||||||
|
==========================
|
||||||
|
This section tries to come up with some kind of guidelines in terms of
|
||||||
|
what dump targets are supported/not supported. Whatever is listed here
|
||||||
|
is not binding in any manner. It is just sharing of current understanding
|
||||||
|
and if something is not right, this section needs to be edited.
|
||||||
|
|
||||||
|
Following are 3 lists. First one contains supported targets. These are
|
||||||
|
generic configurations which should work and some configuration most
|
||||||
|
likely has worked in testing. Second list is known unsupported targets.
|
||||||
|
These targets we know either don't work or we don't support. And third
|
||||||
|
list is unknown/tech-preview. We either don't yet know the status of kdump
|
||||||
|
on these targets or these are under tech-preview.
|
||||||
|
|
||||||
|
Note, these lists are not set in stone and can be changed at any point of
|
||||||
|
time. Also these lists might not be complete. We will add/remove items to
|
||||||
|
it as we get more testing information. Also, there are many corner cases
|
||||||
|
which can't possibly be listed. For example in general we might be
|
||||||
|
supporting software iscsi but there might be some configurations of it
|
||||||
|
which don't work.
|
||||||
|
|
||||||
|
So if any target is listed in supported section, it does not mean it works
|
||||||
|
in all possible configurations. It just means that in common configurations
|
||||||
|
it should work but there can be issues with particular configurations which
|
||||||
|
are not supported. As we come to know of particular issues, we will keep on
|
||||||
|
updating lists accordingly.

Note on FCoE
|
||||||
|
=====================
|
||||||
|
If you are trying to dump to a software FCoE target, you may encounter OOM
|
||||||
|
issue, because some software FCoE requires more memory to work. In such case,
|
||||||
|
you may need to increase the kdump reserved memory size in "crashkernel="
|
||||||
|
kernel parameter.
|
||||||
|
|
||||||
|
By default, RHEL systems have "crashkernel=auto" in kernel boot arguments.
|
||||||
|
The auto reserved memory size is designed to balance the coverage of use cases
|
||||||
|
and an acceptable memory overhead, so not every use case could fit in, software
|
||||||
|
FCoE is one of the case.
|
||||||
|
|
||||||
|
For hardware FCoE, kdump should work naturally as firmware will do the
|
||||||
|
initialization job. The capture kernel and kdump tools will run just fine.
|
||||||
|
|
||||||
