Petr Pavlu 6dd90afb39 module: Prevent silent truncation of module name in delete_module(2) ... [ Upstream commit a6323bd4e6 ] Passing a module name longer than MODULE_NAME_LEN to the delete_module syscall results in its silent truncation. This really isn't much of a problem in practice, but it could theoretically lead to the removal of an incorrect module. It is more sensible to return ENAMETOOLONG or ENOENT in such a case. Update the syscall to return ENOENT, as documented in the delete_module(2) man page to mean "No module by that name exists." This is appropriate because a module with a name longer than MODULE_NAME_LEN cannot be loaded in the first place.
