ecd77a3261 kbuild: move headers_check rule to usr/include/Makefile
commit 7ecaf069da upstream.

Currently, some sanity checks for uapi headers are done by
scripts/headers_check.pl, which is wired up to the 'headers_check'
target in the top Makefile.

It is true compiling headers has better test coverage, but there
are still several headers excluded from the compile test. I like
to keep headers_check.pl for a while, but we can delete a lot of
code by moving the build rule to usr/include/Makefile.

ef134d8b49 kbuild: remove header compile test
commit fcbb8461fd upstream.

There are both positive and negative options about this feature.
At first, I thought it was a good idea, but actually Linus stated a
negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it
is ugly and annoying.

The baseline I'd like to keep is the compile-test of uapi headers.
(Otherwise, kernel developers have no way to ensure the correctness
of the exported headers.)

I will maintain a small build rule in usr/include/Makefile.
Remove the other header test functionality.

f5cfa47505 kbuild: fix DT binding schema rule to detect command line changes
commit 7a04960560 upstream.

This if_change_rule is not working properly; it cannot detect any
command line change.

The reason is because cmd-check in scripts/Kbuild.include compares
$(cmd_$@) and $(cmd_$1), but cmd_dtc_dt_yaml does not exist here.

For if_change_rule to work properly, the stem part of cmd_* and rule_*
must match. Because this cmd_and_fixdep invokes cmd_dtc, this rule must
be named rule_dtc.

a105629b82 ANDROID: kbuild: avoid excessively long argument lists
With LTO, modules with a large number of compilation units maybe end
up exceeding the for loop argument list in the shell. Reduce the
probability for this happening by including only the modules that have
exported symbols.

35eb457cb8 FROMLIST: kbuild: generate autoksyms.h early
When doing a cold build, autoksyms.h starts empty, and is updated late
in the build process to have visibility over the symbols used by in-tree
drivers. But since the symbol whitelist is known upfront, it can be used
to pre-populate autoksyms.h and maximize the amount of code that can be
compiled to its final state in a single pass, hence reducing build time.

Do this by using gen_autoksyms.sh to initialize autoksyms.h instead of
creating an empty file.

b9cd107f9f FROMLIST: kbuild: split adjust_autoksyms.sh in two parts
In order to prepare the ground for a build-time optimization, split
adjust_autoksyms.sh into two scripts: one that generates autoksyms.h
based on all currently available information (whitelist, and .mod
files), and the other to inspect the diff between two versions of
autoksyms.h and trigger appropriate rebuilds.

c5a5b70cff FROMLIST: kbuild: allow symbol whitelisting with TRIM_UNUSED_KSYMS
CONFIG_TRIM_UNUSED_KSYMS currently removes all unused exported symbols
from ksymtab. This works really well when using in-tree drivers, but
cannot be used in its current form if some of them are out-of-tree.

Indeed, even if the list of symbols required by out-of-tree drivers is
known at compile time, the only solution today to guarantee these don't
get trimmed is to set CONFIG_TRIM_UNUSED_KSYMS=n. This not only wastes
space, but also makes it difficult to control the ABI usable by vendor
modules in distribution kernels such as Android. Being able to control
the kernel ABI surface is particularly useful to ship a unique Generic
Kernel Image (GKI) for all vendors, which is a first step in the
direction of getting all vendors to contribute their code upstream.

As such, attempt to improve the situation by enabling users to specify a
symbol 'whitelist' at compile time. Any symbol specified in this
whitelist will be kept exported when CONFIG_TRIM_UNUSED_KSYMS is set,
even if it has no in-tree user. The whitelist is defined as a simple
text file, listing symbols, one per line.

ea038a5270 bpf, btf: Always output invariant hit in pahole DWARF to BTF transform
[ Upstream commit 2a67a6ccb0 ]

When trying to compile with CONFIG_DEBUG_INFO_BTF enabled, I got this
error:

    % make -s
    Failed to generate BTF for vmlinux
    Try to disable CONFIG_DEBUG_INFO_BTF
    make[3]: *** [vmlinux] Error 1

Compiling again without -s shows the true error (that pahole is
missing), but since this is fatal, we should show the error
unconditionally on stderr as well, not silence it using the `info`
function. With this patch:

    % make -s
    BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
    Failed to generate BTF for vmlinux
    Try to disable CONFIG_DEBUG_INFO_BTF
    make[3]: *** [vmlinux] Error 1

59e2355bdf kbuild: use -S instead of -E for precise cc-option test in Kconfig
[ Upstream commit 3bed1b7b9d ]

Currently, -E (stop after the preprocessing stage) is used to check
whether the given compiler flag is supported.

While it is faster than -S (or -c), it can be false-positive. You need
to run the compilation proper to check the flag more precisely.

For example, -E and -S disagree about the support of
"--param asan-instrument-allocas=1".

$ gcc -Werror --param asan-instrument-allocas=1 -E -x c /dev/null -o /dev/null
$ echo $?
0

$ gcc -Werror --param asan-instrument-allocas=1 -S -x c /dev/null -o /dev/null
cc1: error: invalid --param name ‘asan-instrument-allocas’; did you mean ‘asan-instrument-writes’?
$ echo $?
1

23d3f191a5 kbuild: remove *.tmp file when filechk fails
[ Upstream commit 88fe89a471 ]

Bartosz Golaszewski reports that when "make {menu,n,g,x}config" fails
due to missing packages, a temporary file is left over, which is not
ignored by git.

For example, if GTK+ is not installed:

  $ make gconfig
  *
  * Unable to find the GTK+ installation. Please make sure that
  * the GTK+ 2.0 development package is correctly installed.
  * You need gtk+-2.0 gmodule-2.0 libglade-2.0
  *
  scripts/kconfig/Makefile:208: recipe for target 'scripts/kconfig/gconf-cfg' failed
  make[1]: *** [scripts/kconfig/gconf-cfg] Error 1
  Makefile:567: recipe for target 'gconfig' failed
  make: *** [gconfig] Error 2
  $ git status
  HEAD detached at v5.4
  Untracked files:
    (use "git add <file>..." to include in what will be committed)

          scripts/kconfig/gconf-cfg.tmp

  nothing added to commit but untracked files present (use "git add" to track)

This is because the check scripts are run with filechk, which misses
to clean up the temporary file on failure.

When the line

  { $(filechk_$(1)); } > $@.tmp;

... fails, it exits immediately due to the 'set -e'. Use trap to make
sure to delete the temporary file on exit.

For extra safety, I replaced $@.tmp with $(dot-target).tmp to make it
a hidden file.

8ba34cdadb kconfig: fix broken dependency in randconfig-generated .config
[ Upstream commit c8fb7d7e48 ]

Running randconfig on arm64 using KCONFIG_SEED=0x40C5E904 (e.g. on v5.5)
produces the .config with CONFIG_EFI=y and CONFIG_CPU_BIG_ENDIAN=y,
which does not meet the !CONFIG_CPU_BIG_ENDIAN dependency.

This is because the user choice for CONFIG_CPU_LITTLE_ENDIAN vs
CONFIG_CPU_BIG_ENDIAN is set by randomize_choice_values() after the
value of CONFIG_EFI is calculated.

When this happens, the has_changed flag should be set.

Currently, it takes the result from the last iteration. It should
accumulate all the results of the loop.

Fixes: 3b9a19e089 ("kconfig: loop as long as we changed some symbols in randconfig")

3ebbfdf41d scripts/find-unused-docs: Fix massive false positives
commit 1630146db2 upstream.

scripts/find-unused-docs.sh invokes scripts/kernel-doc to find out if a
source file contains kerneldoc or not.

However, as it passes the no longer supported "-text" option to
scripts/kernel-doc, the latter prints out its help text, causing all
files to be considered containing kerneldoc.

Get rid of these false positives by removing the no longer supported
"-text" option from the scripts/kernel-doc invocation.

bccb1568ba ARM: 8950/1: ftrace/recordmcount: filter relocation types
commit 927d780ee3 upstream.

Scenario 1, ARMv7
=================

If code in arch/arm/kernel/ftrace.c would operate on mcount() pointer
the following may be generated:

 234:   f7ff fffe       bl      0 <__gnu_mcount_nc>
                        234: R_ARM_THM_CALL     __gnu_mcount_nc

The analysis for this problem has been already performed previously,
refer to the link below.

Fix the above problems by allowing only selected reloc types in
__mcount_loc. The list itself comes from the legacy recordmcount.pl
script.

c2227983d5 bpf: Force .BTF section start to zero when dumping from vmlinux
commit df786c9b94 upstream.

While trying to figure out why fentry_fexit selftest doesn't pass for me
(old pahole, broken BTF), I found out that my latest patch can break vmlinux
.BTF generation. objcopy preserves section start when doing --only-section,
so there is a chance (depending on where pahole inserts .BTF section) to
have leading empty zeroes. Let's explicitly force section offset to zero.

Before:

$ objcopy --set-section-flags .BTF=alloc -O binary \
	--only-section=.BTF vmlinux .btf.vmlinux.bin
$ xxd .btf.vmlinux.bin | head -n1
00000000: 0000 0000 0000 0000 0000 0000 0000 0000  ................

After:

$ objcopy --change-section-address .BTF=0 \
	--set-section-flags .BTF=alloc -O binary \
	--only-section=.BTF vmlinux .btf.vmlinux.bin
$ xxd .btf.vmlinux.bin | head -n1
00000000: 9feb 0100 1800 0000 0000 0000 80e1 1c00  ................
          ^BTF magic

As part of this change, I'm also dropping '2>/dev/null' from objcopy
invocation to be able to catch possible other issues (objcopy doesn't
produce any warnings for me anymore, it did before with --dump-section).

3bc95f564d kbuild/deb-pkg: annotate libelf-dev dependency as :native
[ Upstream commit 8ffdc54b6f ]

Cross compiling the x86 kernel on a non-x86 build machine produces
the following error when CONFIG_UNWINDER_ORC is enabled, regardless
of whether libelf-dev is installed or not.

  dpkg-checkbuilddeps: error: Unmet build dependencies: libelf-dev
  dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
  dpkg-buildpackage: warning: (Use -d flag to override.)

Since this is a build time dependency for a build tool, we need to
depend on the native version of libelf-dev so add the appropriate
annotation.

c8b4a8e3b6 bpf: Support pre-2.25-binutils objcopy for vmlinux BTF
commit da5fb18225 upstream.

If vmlinux BTF generation fails, but CONFIG_DEBUG_INFO_BTF is set,
.BTF section of vmlinux is empty and kernel will prohibit
BPF loading and return "in-kernel BTF is malformed".

--dump-section argument to binutils' objcopy was added in version 2.25.
When using pre-2.25 binutils, BTF generation silently fails. Convert
to --only-section which is present on pre-2.25 binutils.

Documentation/process/changes.rst states that binutils 2.21+
is supported, not sure those standards apply to BPF subsystem.

v2:
* exit and print an error if gen_btf fails (John Fastabend)

v3:
* resend with Andrii's Acked-by/Tested-by tags

ba7c39e92b kconfig: don't crash on NULL expressions in expr_eq()
[ Upstream commit 272a721030 ]

NULL expressions are taken to always be true, as implemented by the
expr_is_yes() macro and by several other functions in expr.c. As such,
they ought to be valid inputs to expr_eq(), which compares two
expressions.

3346358055 gcc-plugins: make it possible to disable CONFIG_GCC_PLUGINS again
commit a5b0dc5a46 upstream.

I noticed that randconfig builds with gcc no longer produce a lot of
ccache hits, unlike with clang, and traced this back to plugins
now being enabled unconditionally if they are supported.

I am now working around this by adding

   export CCACHE_COMPILERCHECK=/usr/bin/size -A %compiler%

to my top-level Makefile. This changes the heuristic that ccache uses
to determine whether the plugins are the same after a 'make clean'.

However, it also seems that being able to just turn off the plugins is
generally useful, at least for build testing it adds noticeable overhead
but does not find a lot of bugs additional bugs, and may be easier for
ccache users than my workaround.

70958af3e2 scripts/kallsyms: fix definitely-lost memory leak
[ Upstream commit 21915eca08 ]

build_initial_tok_table() overwrites unused sym_entry to shrink the
table size. Before the entry is overwritten, table[i].sym must be freed
since it is malloc'ed data.

This fixes the 'definitely lost' report from valgrind. I ran valgrind
against x86_64_defconfig of v5.4-rc8 kernel, and here is the summary:

[Before the fix]

  LEAK SUMMARY:
     definitely lost: 53,184 bytes in 2,874 blocks

[After the fix]

  LEAK SUMMARY:
     definitely lost: 0 bytes in 0 blocks

1332e29038 dtc: Use pkg-config to locate libyaml
[ Upstream commit 067c650c45 ]

Using Makefile's wildcard with absolute path to detect
the presence of libyaml results in false-positive
detection when cross-compiling e.g. in yocto environment.
The latter results in build error:
| scripts/dtc/yamltree.o: In function `yaml_propval_int':
| yamltree.c: undefined reference to `yaml_sequence_start_event_initialize'
| yamltree.c: undefined reference to `yaml_emitter_emit'
| yamltree.c: undefined reference to `yaml_scalar_event_initialize'
...
Use pkg-config to locate libyaml to address this scenario.

ae14b5c962 ANDROID: init: ensure initcall ordering with LTO
With LTO, the compiler doesn't necessarily obey link order for
initcalls, and the initcall variables need to be globally unique
to avoid naming collisions.

In order to preserve the intended order, this change moves each
initcall variable into its own section and generates a linker
script (in scripts/link-vmlinux.sh) to define the correct order
for these sections. We also add a __COUNTER__ prefix to the name,
so we can retain the order of initcalls within each compilation
unit, and __LINE__ to help ensure uniqueness.

With CONFIG_LTO_CLANG enabled, LLVM IR won't be compiled into object
files until modpost_link. This change postpones calls to recordmcount
until after this step.

In order to exclude ftrace_process_locs from inspection, we add a new
code section .text..ftrace, which we tell recordmcount to ignore, and
a __norecordmcount attribute for moving functions to this section.

2e39b40dd2 ANDROID: kbuild: add support for Clang LTO
This change adds the configuration option CONFIG_LTO_CLANG, and
build system support for Clang's Link Time Optimization (LTO). In
preparation for LTO support with other compilers, potentially common
parts of the changes are gated behind CONFIG_LTO instead.

With -flto, instead of object files, Clang produces LLVM bitcode,
which is compiled into a native object at link time, allowing the
final binary to be optimized globally. For more details, see:

  https://llvm.org/docs/LinkTimeOptimization.html

While the kernel normally uses GNU ld for linking, LLVM supports LTO
only with LLD or GNU gold linkers. This change assumes LLD is used.

65e1f38d9a scripts/tools-support-relr.sh: un-quote variables
When the CC variable contains quotes, e.g. when using
ccache (make CC="ccache <compiler>"), this script always
fails, so CONFIG_RELR is never enabled, even when the
toolchain supports this feature. Removing the /dev/null
redirect and invoking the script manually shows the issue:

    $ CC='/usr/bin/ccache clang' ./scripts/tools-support-relr.sh
    ./scripts/tools-support-relr.sh: 7: ./scripts/tools-support-relr.sh: /usr/bin/ccache clang: not found

Fix this by un-quoting the variables.

Before:
    $ make ARCH=arm64 CC='/usr/bin/ccache clang' LD=ld.lld \
        NM=llvm-nm OBJCOPY=llvm-objcopy defconfig
    $ grep RELR .config
    CONFIG_ARCH_HAS_RELR=y

With this change:
    $ make ARCH=arm64 CC='/usr/bin/ccache clang' LD=ld.lld \

    $ grep RELR .config

8731acc506 scripts/gdb: fix debugging modules compiled with hot/cold partitioning
gcc's -freorder-blocks-and-partition option makes it group frequently
and infrequently used code in .text.hot and .text.unlikely sections
respectively.  At least when building modules on s390, this option is
used by default.

gdb assumes that all code is located in .text section, and that .text
section is located at module load address.  With such modules this is no
longer the case: there is code in .text.hot and .text.unlikely, and
either of them might precede .text.

Fix by explicitly telling gdb the addresses of code sections.

It might be tempting to do this for all sections, not only the ones in
the white list.  Unfortunately, gdb appears to have an issue, when
telling it about e.g. loadable .note.gnu.build-id section causes it to
think that non-loadable .note.Linux section is loaded at address 0,
which in turn causes NULL pointers to be resolved to bogus symbols.  So
keep using the white list approach for the time being.

57baec7b1b scripts/nsdeps: make sure to pass all module source files to spatch
The nsdeps script passes a list of the module source files to
generate_deps_for_ns() as a space delimited string named $mod_source_files,
which then passes it to spatch. But since $mod_source_files is not encased
in quotes, each source file in that string is treated as a separate shell
function argument (as $2, $3, $4, etc.).  However, the spatch invocation
only refers to $2, so only the first file out of $mod_source_files is
processed by spatch.

This causes problems (namely, the MODULE_IMPORT_NS() statement doesn't
get inserted) when a module is composed of many source files and the
"main" module file containing the MODULE_LICENSE() statement is not the
first file listed in $mod_source_files. Fix this by encasing
$mod_source_files in quotes so that the entirety of the string is
treated as a single argument and can be referred to as $2.

In addition, put quotes in the variable assignment of mod_source_files
to prevent any shell interpretation and field splitting.

54087918b8 ANDROID: modpost: fix up merge issues due to namespace removal
module namespaces are ripped out at the moment, so the 5.4-rc5 merge
didn't quite go "well" because of that.  This should resolve those
issues.

9e2dd2ca85 Merge tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules fixes from Jessica Yu:

 - Revert __ksymtab_$namespace.$symbol naming scheme back to
   __ksymtab_$symbol, as it was causing issues with depmod.

   Instead, have modpost extract a symbol's namespace from __kstrtabns
   and __ksymtab_strings.

 - Fix `make nsdeps` for out of tree kernel builds (make O=...) caused
   by unescaped '/'.

   Use a different sed delimiter to avoid this problem.

* tag 'modules-for-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
  scripts/nsdeps: use alternative sed delimiter
  symbol namespaces: revert to previous __ksymtab name scheme
  modpost: make updating the symbol namespace explicit
  modpost: delegate updating namespaces to separate function

3fde1dfb00 ANDROID: Revert "Merge tag 'modules-for-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux"
This reverts commit e070355664, reversing
changes made to 8808cf8cbc.

Introducing symbol-namespaces into the kernel has caused issues with
respect to the ABI checker. Hence, revert the changes until a valid
fix is available. The revert was done based off of 5.4-rc1.
