Hm, that's odd. I haven't seen anything like that before. Maybe changes to non-bundled sections could be downgraded to warnings. Or if this seems like a fluke we could do KPATCH_IGNORE_SECTION() for that patch.
- special-static.patch was introduced to verify that kpatch-build could handle
__warned
and__key
so-called special static local variables. Do these special symbols need to exist in kpatch-modified functions, or merely somewhere in kpatch-modified object files?
I'm not 100% sure, but I think the current test triggers a change in a function which actually uses such variables, so let's stick with that :-)
- Could this be turned into an unit test? The patch doesn't do much, and nothing I see specifically regarding the special symbols.
Yeah, I think so.
from kpatch.
Here are the object files for special-static.patch as built on RHEL-9.3:
special-static-objs.tar.gz
It looks like copy_signal() only references a few __key variables, though the greater fork.o file a few others (like __already_done
, _entry
, and __func__
). If that's good enough, then I can push the stripped objects into the unit-test repo and deprecate the special-static.patch.
