[ Upstream commit 23dfd914d2bfc4c9938b0084dffd7105de231d98 ] If the find_fromsym() call fails and returns NULL, the warn() call will dereference this NULL pointer and cause the program to crash. This happened when I tried to build with "test_user_copy" module. With this fix, it prints lots of warnings like this: WARNING: modpost: lib/test_user_copy: section mismatch in reference: (unknown)+0x4 (section: .text.fixup) -> (unknown) (section: .init.text) masahiroy@kernel.org: The issue is reproduced with ARCH=arm allnoconfig + CONFIG_MODULES=y + CONFIG_RUNTIME_TESTING_MENU=y + CONFIG_TEST_USER_COPY=m Signed-off-by: Max Kellermann <max.kellermann@ionos.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org> |
