Subject: [PATCH 1/2] Makefile: set DT_SONAME to trace.so
|
||||
|
||||
Fedora never requires SONAME versioning for plugins according to the
|
||||
Packaging Guidelines:
|
||||
|
||||
https://docs.fedoraproject.org/en-US/packaging-guidelines/#_downstream_so_name_versioning
|
||||
|
||||
In cases where upstream ships unversioned .so library (so this is
|
||||
not needed for plugins, drivers, etc.), the packager MUST try to
|
||||
convince upstream to start versioning it.
|
||||
|
||||
On the other hand, fedpkg lint still prints warning if the shared
|
||||
library doesn't have DT_SONAME. To surpress this, we set DT_SONAME
|
||||
field to trace.so for in case.

Subject: [PATCH] trace: Support module memory layout change on Linux 6.4
|
||||
|
||||
Linux kernel introduced new module memory layout on Linux 6.4 at the
|
||||
commit ac3b432 (module: replace module_layout with module_memory) and
|
||||
crash utility supported it at the commit 7750e61 (Support module
|
||||
memory layout change on Linux 6.4).
|
||||
|
||||
In the change, crash utility changed definition and usage of data
|
||||
structure for kernel modules. However, crash trace also refers to the
|
||||
data structures. As a result, with the crash utility with the change,
|
||||
crash trace command results in segmentation fault:
|
||||
|
||||
crash> extend trace.so
|
||||
/usr/lib64/crash/extensions/trace.so: shared object loaded
|
||||
crash> trace show
|
||||
Segmentation fault (core dumped)
|
||||
|
||||
To fix this issue, let's support the new definition and usage of
|
||||
struct load_module in crash trace. This is at the same time intended
|
||||
for crash trace to support the new module memory layout of the Linux
|
||||
kernel.
|
||||
|
||||
On the other hand, there is still inevitable dependency left to size
|
||||
of struct load_module, one of the data structures of crash utility, in
|
||||
crash trace. struct symbol_table_data holds an array of objects of
|
||||
struct load_module in member variable load_modules and we need to know
|
||||
size of struct load_module in advance to refer to its elements.
|
||||
|
||||
struct symbol_table_data {
|
||||
...snip...
|
||||
int mods_installed;
|
||||
struct load_module *current;
|
||||
struct load_module *load_modules;
|
||||
|
||||
Due to this, once crash trace is built with the defs.h including
|
||||
change of size of struct load_module, it can never be used with the
|
||||
older crash utility that was built with a different size of struct
|
||||
load_module.
|
||||
|
||||
Because there is no preferable way to tackle the dependency without
|
||||
altering implementation of crash utility, we have no choice but accept
|
||||
breaking backward-compatibility for the time being.

Subject: [PATCH 2/2] Makefile: fix build failure on aarch64 and ppc64le
|
||||
|
||||
Currently, there is build failure on aarch64 and ppc64le as follows:
|
||||
|
||||
gcc -O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mcpu=power8 -mtune=power8 -fasynchronous-unwind-tables -fstack-clash-protection -Wall -I/usr/include/crash -nostartfiles -shared -rdynamic -o trace.so trace.c -fPIC -D
|
||||
gcc: error: macro name missing after '-D'
|
||||
|
||||
The failure is caused by missing arguments for -D option because
|
||||
TARGET variable is empty.
|
||||
|
||||
This commit fixes the issue by defining TARGET variable properly
|
||||
according to aarch64 and ppc64le.
