[PATCH] Avoid false-positive mem_section validation with vmlinux
Currently get_mem_section() validates if SYMBOL(mem_section) is the address
of the mem_section array first. But there was a report that the first
validation wrongly returned TRUE with -x vmlinux and SPARSEMEM_EXTREME
(4.15+) on s390x. This leads to crash failing statup with the following
seek error:
crash: seek error: kernel virtual address: 67fffc2800 type: "memory section root table"
Skip the first validation when satisfying the conditions.

Newer s390 kernels support a command line size longer than 896

which might be utilized by tools like kexec. Older kernels have
the location initialized to zero, so we check whether there's a
non-zero number present and use that. If there isn't, we fallback
to the legacy command line size of 896 bytes.

util_lib/elf_info: harden parsing of printk buffer
The old printk mechanism (> v3.5.0 and < v5.10.0) had a fixed size
buffer (log_buf) that contains all messages. The location for the next
message is stored in log_next_idx. In case the log_buf runs full
log_next_idx wraps around and starts overwriting old messages at the
beginning of the buffer. The wraparound is denoted by a message with
msg->len == 0.
Following the behavior described above blindly is dangerous as e.g. a
memory corruption could overwrite (parts of) the log_buf. If the
corruption adds a message with msg->len == 0 this leads to an endless
loop when dumping the dmesg. Fix this by verifying that not wrapped
around before when it encounters a message with msg->len == 0.
While at it also verify that the index is within the log_buf and thus
guard against corruptions with msg->len != 0.
The same bug has been reported and fixed in makedumpfile [1].

[PATCH] print error when reading with unsupported compression
Currently makedumpfile only checks if the required compression algorithm
was enabled during build when compressing a dump but not when reading
from one. This can lead to situations where, one version of makedumpfile
creates the dump using a compression algorithm an other version of
makedumpfile doesn't support. When the second version now tries to, e.g.
extract the dmesg from the dump it will fail with an error similar to
# makedumpfile --dump-dmesg vmcore dmesg.txt
__vtop4_x86_64: Can't get a valid pgd.
readmem: Can't convert a virtual address(ffffffff92e18284) to physical address.
readmem: type_addr: 0, addr:ffffffff92e18284, size:390
check_release: Can't get the address of system_utsname.
makedumpfile Failed.
That's because readpage_kdump_compressed{_parallel} does not return
with an error if the page it is trying to read is compressed with an
unsupported compression algorithm. Thus readmem copies random data from
the (uninitialized) cachebuf to its caller and thus causing the error
above.
Fix this by checking if the required compression algorithm is supported
in readpage_kdump_compressed{_parallel} and print a proper error message
if it isn't.

message is stored in log_next_idx. In case the log_buf runs full

the messages up to the corruption over and over again to the output file
until file system is full. Fix this by using cycle detection and aboard
once one is detected.
While at it also verify that the index is within the log_buf and thus
guard against corruptions with msg->len != 0.

[PATCH v2 1/3] add generic cycle detection
In order to work makedumpfile needs to interpret data read from the
dump. This can cause problems as the data from the dump cannot be
trusted (otherwise the kernel wouldn't have panicked in the first
place). This also means that every loop which stop condition depend on
data read from the dump has a chance to loop forever. Thus add a generic
cycle detection mechanism that allows to detect and handle such
situations appropriately.
For cycle detection use Brent's algorithm [1] as it has constant memory
usage. With this it can also be used in the kdump kernel without the
danger that it runs oom when iterating large data structures.
Furthermore it only depends on some pointer arithmetic. Thus the
performance impact (as long as no cycle was detected) should be
comparatively small.

This is caused by the kernel commit 9d06c4027f21 ("x86/entry: Convert

asm_exc_divide_error, breaking logic for calculating kaslr offset.
Fix this by adding initialization of asm_exc_divide_error.

update kernel crashkernel in posttrans RPM scriptlet when updating kexec-tools
When doing in-place upgrading using leapp on x86_64, kdumpcl can't
acquire instance lock when running in %post RPM scriplet on x86_64,
localhost upgrade[1306]: /bin/kdumpctl: line 49: /var/lock/kdump: No such file or directory
localhost upgrade[1306]: kdump: Create file lock failed
and running "touch /var/lock/dkump" also fails with
"No such file or directory". Thus kdumpctl can't be run in %post
scriptlet. But kdumpctl can be run in %posttrans RPM scriplet.
Besides, it's better to update crashkernel after the kernel has been
updated. So let's update kernel crashkernel in the %posttrans
scriptlet which will be run in the end of a transaction i.e. after
the kernel has been updated.
Note for %posttrans scriptlet, "$1 == 1" means both installing a new
package and upgrading a package.

s390: handle R_390_PLT32DBL reloc entries in machine_apply_elf_rel()
Starting with gcc 11.3, the C compiler will generate PLT-relative function
calls even if they are local and do not require it. Later on during linking,
the linker will replace all PLT-relative calls to local functions with
PC-relative ones. Unfortunately, the purgatory code of kexec/kdump is
not being linked as a regular executable or shared library would have been,
and therefore, all PLT-relative addresses remain in the generated purgatory
object code unresolved. This in turn lets kexec-tools fail with
"Unknown rela relocation: 0x14 0x73c0901c" for such relocation types.
Furthermore, the clang C compiler has always behaved like described above
and this commit should fix the purgatory code built with the latter.
Because the purgatory code is no regular executable or shared library,
contains only calls to local functions and has no PLT, all R_390_PLT32DBL
relocation entries can be resolved just like a R_390_PC32DBL one.

try to reset kernel crashkernel when kexec-tools updates the default crashkernel value
kexec-tools could update the default crashkernel value.
When auto_reset_crashkernel=yes, reset kernel to new crashkernel
value in the following two cases,
- crashkernel=auto is found in the kernel cmdline
- the kernel crashkernel was previously set by kexec-tools i.e.
the kernel is using old default crashkernel value
To tell if the user is using a custom value for the kernel crashkernel
or not, we assume the user would never use the default crashkernel value
as custom value. When kexec-tools gets updated,
1. save the default crashkernel value of the older package to
/tmp/crashkernel (for POWER system, /tmp/crashkernel_fadump is saved
as well).
2. If auto_reset_crashkernel=yes, iterate all installed kernels.
For each kernel, compare its crashkernel value with the old
default crashkernel and reset it if yes
The implementation makes use of two RPM scriptlets [2],
- %pre is run before a package is installed so we can use it to save
old default crashkernel value
- %post is run after a package installed so we can use it to try to reset
kernel crashkernel
There are several problems when running kdumpctl in the RPM scripts
for CoreOS/Atomic/Silverblue, for example, the lock can't be acquired by
kdumpctl, "rpm-ostree kargs" can't be run and etc.. So don't enable this
feature for CoreOS/Atomic/Silverblue.
Note latest shellcheck (0.8.0) gives false positives about the
associative array as of this commit. And Fedora's shellcheck is 0.7.2
and can't even correctly parse the shell code because of the associative
array.

Remove references to systemd-sysv-convert
Packaging guidelines have been amended to not require systemd for scriptlets,
see https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_scriptlets.
The comment duplicates what the macro contains.
systemd-sysv-convert binary was removed in 2013, trying to call it is
unlikely to succeed.
chkconfig binary is provided by the chkconfig package, which is not in
Requires. (And makes little sense to call nowadays anyway.)

kdump/ppc64: suppress the error message "Could not find a registered notification tool" from servicelog_notify
When kexec-tools is newly installed, kdump migration action hasn't
registered and the following error could occur,
INF dnf.rpm: Could not find a registered notification tool with the specified command ('/usr/lib/kdump/kdump-migrate-action.sh').
"servicelog_notify --list" could list registered notification tools for
a command but it outputs the above error as well. So simply redirect the
error to /dev/null when running "servicelog_notify --remove".

Merge kdump-error-handler.sh into kdump.sh
kdump-error-handler.sh does nothing except calling three functions,
it can be easily merged into kdump.sh by using a parameter to run the
error handling routine.
kdump-lib-initramfs.sh was created to hold the three shared functions
and related code, so by merging these two files, kdump-lib-initramfs.sh
can be simplified by a lot.
Following up commits will clean up kdump-lib-initramfs.sh.

fadump: isolate fadump initramfs image within the default one
In case of fadump, the initramfs image has to be built to boot into
the production environment as well as to offload the active crash dump
to the specified dump target (for boot after crash). As the same image
would be used for both boot scenarios, it could not be built optimally
while accommodating both cases.
Use --include to include the initramfs image built for offloading
active crash dump to the specified dump target. Also, introduce a new
out-of-tree dracut module (99zz-fadumpinit) that installs a customized
init program while moving the default /init to /init.dracut. This
customized init program is leveraged to isolate fadump image within
the default initramfs image by kicking off default boot process
(exec /init.dracut) for regular boot scenario and activating fadump
initramfs image, if the system is booting after a crash.
If squash is available, ensure default initramfs image is also built
with squash module to reduce memory consumption in capture kernel.
