security: export security_kernel_load_data function

arndb · James Morris · commit 83a68a06795f · 2018-07-17T21:26:51.000-07:00
The firmware_loader can be built as a loadable module, which now fails when CONFIG_SECURITY is enabled, because a call to the security_kernel_load_data() function got added, and this is not exported to modules: ERROR: "security_kernel_load_data" [drivers/base/firmware_loader/firmware_class.ko] undefined! Add an EXPORT_SYMBOL_GPL() to make it available here. Fixes: 6e85265 ("firmware: add call to LSM hook before firmware sysfs fallback") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: James Morris <james.morris@microsoft.com>
