      Fix: module signature vs tracepoints: add new TAINT_UNSIGNED_MODULE · 66cc69e3
      Mathieu Desnoyers authored
      Users have reported being unable to trace non-signed modules loaded
      within a kernel supporting module signature.
      
      This is caused by tracepoint.c:tracepoint_module_coming() refusing to
      take into account tracepoints sitting within force-loaded modules
      (TAINT_FORCED_MODULE). The reason for this check, in the first place, is
      that a force-loaded module may have a struct module incompatible with
      the layout expected by the kernel, and can thus cause a kernel crash
      upon forced load of that module on a kernel with CONFIG_TRACEPOINTS=y.
      
      Tracepoints, however, specifically accept TAINT_OOT_MODULE and
      TAINT_CRAP, since those modules do not lead to the "very likely system
      crash" issue cited above for force-loaded modules.
      
      With kernels having CONFIG_MODULE_SIG=y (signed modules), a non-signed
      module is tainted re-using the TAINT_FORCED_MODULE taint flag.
      Unfortunately, this means that Tracepoints treat that module as a
      force-loaded module, and thus silently refuse to consider any tracepoint
      within this module.
      
      Since an unsigned module does not fit within the "very likely system
      crash" category of tainting, add a new TAINT_UNSIGNED_MODULE taint flag
      to specifically address this taint behavior, and accept those modules
      within Tracepoints. We use the letter 'X' as a taint flag character for
      a module being loaded that doesn't know how to sign its name (proposed
      by Steven Rostedt).
      
      Also add the missing 'O' entry to trace event show_module_flags() list
      for the sake of completeness.

      module: remove MODULE_GENERIC_TABLE · cff26a51
      Rusty Russell authored
      MODULE_DEVICE_TABLE() calles MODULE_GENERIC_TABLE(); make it do the
      work directly.  This also removes a wart introduced in the last patch,
      where the alias is defined to be an unknown struct type "struct
      type##__##name##_device_id" instead of "struct type##_device_id" (it's
      an extern so GCC doesn't care, but it's wrong).
      
      The other user of MODULE_GENERIC_TABLE (ISAPNP_CARD_TABLE) is unused,
      so delete it.

      module: allow multiple calls to MODULE_DEVICE_TABLE() per module · 21bdd17b
      Tom Gundersen authored
      Commit 78551277: "Input: i8042 - add PNP modaliases" had a bug, where the
      second call to MODULE_DEVICE_TABLE() overrode the first resulting in not all
      the modaliases being exposed.
      
      This fixes the problem by including the name of the device_id table in the
      __mod_*_device_table alias, allowing us to export several device_id tables
      per module.

      Pull thermal fixes from Zhang Rui:
       "Specifics:
      
         - Update the help text of INT3403 Thermal driver, which was not
           friendly to users.  From Zhang Rui.
      
         - The "type" sysfs attribute of x86_pkg_temp_thermal registered
           thermal zones includes an instance number, which makes the
           thermal-to-hwmon bridge fails to group them all in a single hwmon
           device.  Fixed by Jean Delvare.
      
         - The hwmon device registered by x86_pkg_temp_thermal driver is
           redundant because the temperature value reported by
           x86_pkg_temp_thermal is already reported by the coretemp driver.
           Fixed by Jean Delvare.
      
         - Fix a problem that the cooling device can not be updated properly
           if it is initialized at max cooling state.  From Ni Wade.
      
         - Fix a problem that OF registered thermal zones are running without
           thermal governors.  From Zhang Rui.
      
         - Commit beeb5a1e ("thermal: rcar-thermal: Enable driver
           compilation with COMPILE_TEST") broke build on archs wihout io
           memory.  Thus make it depend on HAS_IOMEM to bypass build failures.
