      module: setup load info before module_sig_check() · 5fdc7db6
      Jessica Yu 提交于
      We want to be able to log the module name in early error messages, such as
      when module signature verification fails.  Previously, the module name is
      set in layout_and_allocate(), meaning that any error messages that happen
      before (such as those in module_sig_check()) won't be logged with a module
      name, which isn't terribly helpful.
      
      In order to do this, reshuffle the order in load_module() and set up
      load info earlier so that we can log the module name along with these
      error messages. This requires splitting rewrite_section_headers() out of
      setup_load_info().
      
      While we're at it, clean up and split up the operations done in
      layout_and_allocate(), setup_load_info(), and rewrite_section_headers()
      more cleanly so these functions only perform what their names suggest.

      module: make it clear when we're handling the module copy in info->hdr · 81a0abd9
      Jessica Yu 提交于
      In load_module(), it's not always clear whether we're handling the
      temporary module copy in info->hdr (which is freed at the end of
      load_module()) or if we're handling the module already allocated and
      copied to it's final place. Adding an info->mod field and using it
      whenever we're handling the temporary copy makes that explicitly clear.

      module: exclude SHN_UNDEF symbols from kallsyms api · 9f2d1e68
      Jessica Yu 提交于
      Livepatch modules are special in that we preserve their entire symbol
      tables in order to be able to apply relocations after module load. The
      unwanted side effect of this is that undefined (SHN_UNDEF) symbols of
      livepatch modules are accessible via the kallsyms api and this can
      confuse symbol resolution in livepatch (klp_find_object_symbol()) and
      cause subtle bugs in livepatch.
      
      Have the module kallsyms api skip over SHN_UNDEF symbols. These symbols
      are usually not available for normal modules anyway as we cut down their
      symbol tables to just the core (non-undefined) symbols, so this should
      really just affect livepatch modules. Note that this patch doesn't
      affect the display of undefined symbols in /proc/kallsyms.
