This is the third batch of cleanups in this development cycle.
Major changes in v4:
- Move static EXPORT_SYMBOL check to a script
- Some refactoring
Major changes in v3:
- Generate symbol CRCs as C code, and remove CONFIG_MODULE_REL_CRCS.
Major changes in v2:
- V1 did not work with CONFIG_MODULE_REL_CRCS.
I fixed this for v2.
- Reflect some review comments in v1
- Refactor the code more
- Avoid too long argument error
Masahiro Yamada (14):
modpost: remove left-over cross_compile declaration
modpost: change the license of EXPORT_SYMBOL to bool type
modpost: split the section mismatch checks into section-check.c
modpost: add sym_find_with_module() helper
modpost: extract symbol versions from *.cmd files
kbuild: link symbol CRCs at final link, removing
CONFIG_MODULE_REL_CRCS
kbuild: stop merging *.symversions
genksyms: adjust the output format to modpost
kbuild: do not create *.prelink.o for Clang LTO or IBT
kbuild: check static EXPORT_SYMBOL* by script instead of modpost
kbuild: make built-in.a rule robust against too long argument error
kbuild: make *.mod rule robust against too long argument error
kbuild: add cmd_and_savecmd macro
kbuild: rebuild multi-object modules when objtool is updated

The following commits removed unused ones. - f1c3d73e973c ("module: remove EXPORT_SYMBOL_GPL_FUTURE") - 367948220fce ("module: remove EXPORT_UNUSED_SYMBOL*") There are 3 remaining in enum export, but export_unknown does not make any sense because we never expect such a situation like "we do not know how it was exported". If the symbol name starts with "__ksymtab_", but the section name does not start with "___ksymtab+" or "___ksymtab_gpl+", it is not an exported symbol. It occurs when a variable starting with "__ksymtab_" is directly defined: int __ksymtab_foo; Presumably, there is no practical issue for using such a weird variable name (but there is no good reason for doing so, either). Anyway, that is not an exported symbol. Setting export_unknown is not the right thing to do. Do not call sym_add_exported() in this case. With pointless export_unknown removed, the export type finally becomes boolean (either EXPORT_SYMBOL or EXPORT_SYMBOL_GPL). I renamed the field name to is_gpl_only. EXPORT_SYMBOL_GPL sets it true. Only GPL-compatible modules can use it. I removed the orphan comment, "How a symbol is exported", which is unrelated to sec_mismatch_count. It is about enum export.

Yeah, you need to _declare_ it w/ extern in the header, then _define_ it in one source file. That way, if the type ever changes, the sources will agree on type in all source files. You will get a redefinition error if the definition changes the type of the variable since the last declaration. What you're doing is forward declaring, which works, and is a common pattern for (bloated) C++, but is less type safe than sharing a single common declaration between multiple source files via a single common shared header.

Then, modpost extracts the version CRCs from them. The following figures show how it currently works, and how I am trying to change it. Current implementation ====================== |----------| embed CRC -------------------------->| final | $(CC) $(LD) / |---------| | link for | -----> *.o -------> *.o -->| modpost | | vmlinux | / / | |-- *.mod.c -->| or | / genksyms / |---------| | module | *.c ------> *.symversions |----------| Genksyms outputs the calculated CRCs in the form of linker script (*.symversions), which is used by $(LD) to update the object. If CONFIG_LTO_CLANG=y, the build process is much more complex. Embedding the CRCs is postponed until the LLVM bitcode is converted into ELF, creating another intermediate *.prelink.o. However, this complexity is unneeded. There is no reason why we must embed version CRCs in objects so early. There is final link stage for vmlinux (scripts/link-vmlinux.sh) and modules (scripts/Makefile.modfinal). We can link CRCs at the very last moment. New implementation ================== |----------| --------------------------------------->| final | $(CC) / |---------| | link for | -----> *.o ---->| | | vmlinux | / | modpost |--- .vmlinux.export.c -->| or | / genksyms | |--- *.mod.c ------------>| module | *.c ------> *.cmd -->|---------| |----------| Pass the symbol versions to modpost as separate text data, which are available in *.cmd files.

Genksyms writes the version CRCs into the linker script, which will be used for filling the __crc_* symbols. The linker script format depends on CONFIG_MODULE_REL_CRCS. If it is enabled, __crc_* holds the offset to the reference of CRC. It is time to get rid of this complexity. Now that modpost parses text files (.*.cmd) to collect all the CRCs, it can generate C code that will be linked to the vmlinux or modules. Generate a new C file, .vmlinux.export.c, which contains the CRCs of symbols exported by vmlinux. It is compiled and linked to vmlinux in scripts/link-vmlinux.sh. Put the CRCs of symbols exported by modules into the existing *.mod.c files. No additional build step is needed for modules. As before, *.mod.c are compiled and linked to *.ko in scripts/Makefile.modfinal. No linker magic is used here. The new C implementation works in the same way, whether CONFIG_RELOCATABLE is enabled or not. CONFIG_MODULE_REL_CRCS is no longer needed. Previously, Kbuild invoked additional $(LD) to update the CRCs in objects, but this step is unneeded too.

You can find detailed explanation in scripts/basic/fixdep.c In short, it works like this: fixdep parses every source (including headers). If it finds "CONFIG_MODVERSIONS", it adds a dependency on $(wildcard include/config/MODVERSIONS) to the .cmd files. If CONFIG_MODVERSIONS is toggled in Kconfig, it touches include/config/MODVERSIONS. [1] In the next run of Make, all the sources depending on CONFIG_MODVERSIONS will be re-compiled because the timestamp of include/config/MODVERSIONS is up-to-date.

Also, objtool is postponed until LLVM bitcode is converted to ELF. CONFIG_X86_KERNEL_IBT works in a similar way to postpone objtool until objects are merged together. This commit stops generating *.prelink.o, so the build flow will look the same with/without LTO. The following figures show how the LTO build currently works, and how this commit is changing it.

New build flow ============== [1] single-object module Since there is only one object, we do not need to have the LLVM bitcode stage. Use $(CC)+$(LD) to generate an ELF object in one build rule.

Commit 15bfc2348d54 ("modpost: check for static EXPORT_SYMBOL* functions") tried to detect it, but this check has false negatives. Here is the sample code. Makefile: obj-y += foo1.o foo2.o foo1.c: #include <linux/export.h> static void foo(void) {} EXPORT_SYMBOL(foo); foo2.c: void foo(void) {} foo1.c exports the static symbol 'foo', but modpost cannot catch it because it is fooled by foo2.c, which has a global symbol with the same name. s->is_static is cleared if a global symbol with the same name is found somewhere, but EXPORT_SYMBOL() and the global symbol do not necessarily belong to the same compilation unit. This check should be done per compilation unit, but I do not know how to do it in modpost. modpost runs against vmlinux.o or modules, which merges multiple objects, then forgets their origin. It is true modpost gets access to the lists of all the member objects (.vmlinux.objs and *.mod), but it is impossible to parse individual objects in modpost; they might be LLVM IR instead of ELF when CONFIG_LTO_CLANG=y. Add a simple bash script to parse the output from ${NM}. This works for CONFIG_LTO_CLANG=y because llvm-nm can dump symbols of LLVM bitcode. Revert 15bfc2348d54.

I think this design is nice overall but some commands have a scalability issue. The build command of built-in.a is one of them whose length scales with: O(D * N) Here, D is the length of the directory path (i.e. $(obj)/ prefix), N is the number of objects in the Makefile, O() is the big O notation. The deeper directory the Makefile directory is located, the more easily it will hit the too long argument error. We can make it better. Trim the $(obj)/ by Make's builtin function, and restore it by a shell command (sed). With this, the command length scales with: O(D + N) In-tree modules still have some room to the limit (ARG_MAX=2097152), but this is more future-proof for big modules in a deep directory. For example, you can build i915 as builtin (CONFIG_DRM_I915=y) and compare drivers/gpu/drm/i915/.built-in.a.cmd with/without this commit.

Add $(obj)/ by the shell command (awk) instead of by Make's builtin function. In-tree modules still have some room to the limit (ARG_MAX=2097152), but this is more future-proof for big modules in a deep directory. For example, you can build i915 as a module (CONFIG_DRM_I915=m) and compare drivers/gpu/drm/i915/.i915.mod.cmd with/without this commit. The issue is more critical for external modules because the M= path can be very long as Jeff Johnson reported before [1].
