| | | | | What's Going On? Back in February 2020, there were some stirrings on the LKML about unexporting kallsyms_lookup_name() from the kernel. The main reason for this is that unscrupulous module developers will often simply add MODULE_LICENSE('GPL') to their code (without actually licensing their module as such). Then, using kallsyms_lookup_name(), they can use any other exported kernel function to their heart's content. The kernel developers don't like this because it enables out-of-tree modules to call non-exported functions. | |
