Pull input fix from Dmitry Torokhov:
 "A fix for a broken commit in the previous pull breaking automatic
  module loading of input handlers, such ad evdev"

Input: do not use property bits when generating module alias

2017-10-22T19:49:59+00:00

The commit 8724ecb07229 ("Input: allow matching device IDs on property
bits") started using property bits when generating module aliases for input
handlers, but did not adjust the generation of MODALIAS attribute on input
device uevents, breaking automatic module loading. Given that no handler
currently uses property bits in their module tables, let's revert this part
of the commit for now.

Let's allow matching input devices on their property bits, both in-kernel
and when generating module aliases.

Merge tag 'modules-for-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux

2017-09-13T18:28:19+00:00

Pull modules updates from Jessica Yu:
 "Summary of modules changes for the 4.14 merge window:

   - minor code cleanups and fixes

   - modpost: avoid building modules that have names that exceed the
     size of the name field in struct module"

* tag 'modules-for-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
  module: Remove const attribute from alias for MODULE_DEVICE_TABLE
  module: fix ddebug_remove_module()
  modpost: abort if module name is too long

modpost: simplify sec_name()

2017-09-07T00:27:24+00:00

There is code duplication between sec_name() and sech_name().  Simplify
sec_name() by re-using sech_name().  Also, move them up to remove the
forward declaration of sec_name().

modpost: abort if module name is too long

2017-07-25T13:08:19+00:00

Module name has a limited length, but currently the build system
allows the build finishing even if the module name is too long.

  CC      /root/kprobe_example/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.mod.o
 /root/kprobe_example/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.mod.c:9:2:
 warning: initializer-string for array of chars is too long [enabled by default]
  .name = KBUILD_MODNAME,
  ^

but it's merely a warning.

This patch adds the check of the module name length in modpost and stops
the build properly.

module: Add module name to modinfo

2017-05-23T21:08:31+00:00

Accessing the mod structure (e.g. for mod->name) prior to having completed
check_modstruct_version() can result in writing garbage to the error logs
if the layout of the mod structure loaded from disk doesn't match the
running kernel's mod structure layout. This kind of mismatch will become
much more likely if a kernel is built with different randomization seed
for the struct layout randomization plugin.

Instead, add and use a new modinfo string for logging the module name.

kbuild: Consolidate header generation from ASM offset information

2017-04-12T20:43:37+00:00

Largely redundant code is used in different places to generate C headers
from offset information extracted from assembly language output.
Consolidate the code in Makefile.lib and use this instead.

objtool, modules: Discard objtool annotation sections for modules

2017-03-01T19:32:25+00:00

The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time.  They're discarded for vmlinux but they
should also be discarded for modules.

Since this is a recurring pattern, prefix the section names with
".discard.".  It's a nice convention and vmlinux.lds.h already discards
such sections.

Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.
