Masahiro Yamada 9435dc77a3 modpost: distinguish same module paths from different dump files ... Since commit 13b25489b6 ("kbuild: change working directory to external module directory with M="), module paths are always relative to the top of the external module tree. The module paths recorded in Module.symvers are no longer globally unique when they are passed via KBUILD_EXTRA_SYMBOLS for building other external modules, which may result in false-positive "exported twice" errors. Such errors should not occur because external modules should be able to override in-tree modules. To address this, record the dump file path in struct module and check it when searching for a module. Fixes: 13b25489b6 ("kbuild: change working directory to external module directory with M=") Reported-by: Jon Hunter <jonathanh@nvidia.com> Closes: https://lore.kernel.org/all/eb21a546-a19c-40df-b821-bbba80f19a3d@nvidia.com/ Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Jon Hunter <jonathanh@nvidia.com>		2024-12-21 12:42:10 +09:00
