Hi Steven,
Commit 2860cd8a2353 ("livepatch: Use the default ftrace_ops instead of REGS when ARGS is available") adds a dependency on a non-existing config DYNAMIC_FTRACE_WITH_ARGS, see diff:
diff --git a/kernel/livepatch/Kconfig b/kernel/livepatch/Kconfig index 54102deb50ba..53d51ed619a3 100644 --- a/kernel/livepatch/Kconfig +++ b/kernel/livepatch/Kconfig @@ -6,7 +6,7 @@ config HAVE_LIVEPATCH
config LIVEPATCH bool "Kernel Live Patching" - depends on DYNAMIC_FTRACE_WITH_REGS + depends on DYNAMIC_FTRACE_WITH_REGS || DYNAMIC_FTRACE_WITH_ARGS depends on MODULES depends on SYSFS depends on KALLSYMS_ALL
Did you intend to depend on the existing "HAVE_DYNAMIC_FTRACE_WITH_ARGS" here?
Or did you intend to add a new config DYNAMIC_FTRACE_WITH_ARGS analogously to DYNAMIC_FTRACE_WITH_REGS as defined in ./kernel/trace/Kconfig (see below)?
config DYNAMIC_FTRACE_WITH_REGS def_bool y depends on DYNAMIC_FTRACE depends on HAVE_DYNAMIC_FTRACE_WITH_REGS
I am happy to provide a patch, once I understand what was intended here.
Lukas
