2d578d836a BACKPORT: FROMGIT: kbuild: mkcompile_h: Include $LD version in /proc/version
When doing Clang builds of the kernel, it is possible to link with
either ld.bfd (binutils) or ld.lld (LLVM), but it is not possible to
discover this from a running kernel. Add the "$LD -v" output to
/proc/version.

bf3b3bbdfc ANDROID: kbuild: ensure __cfi_check is correctly aligned
On modules with no executable code, LLVM generates a __cfi_check stub,
but won't align it to page size as expected. This change ensures the
function is at the beginning of the .text section and correctly aligned
for the CFI shadow.

88f7a6aa7f scripts/dtc: Remove redundant YYLOC global declaration
commit e33a814e772cdc36436c8c188d8c42d019fda639 upstream.

gcc 10 will default to -fno-common, which causes this error at link
time:

  (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here

This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:

  dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
   26 | extern YYLTYPE yylloc;
      |                ^~~~~~
In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
  127 | extern YYLTYPE yylloc;
      |                ^~~~~~
cc1: all warnings being treated as errors

which means the declaration is completely redundant and can just be
dropped.

dafda49dfb kbuild: Disable -Wpointer-to-enum-cast
commit 82f2bc2fcc0160d6f82dd1ac64518ae0a4dd183f upstream.

Clang's -Wpointer-to-int-cast deviates from GCC in that it warns when
casting to enums. The kernel does this in certain places, such as device
tree matches to set the version of the device being used, which allows
the kernel to avoid using a gigantic union.

https://elixir.bootlin.com/linux/v5.5.8/source/drivers/ata/ahci_brcm.c#L428
https://elixir.bootlin.com/linux/v5.5.8/source/drivers/ata/ahci_brcm.c#L402
https://elixir.bootlin.com/linux/v5.5.8/source/include/linux/mod_devicetable.h#L264

To avoid a ton of false positive warnings, disable this particular part
of the warning, which has been split off into a separate diagnostic so
that the entire warning does not need to be turned off for clang. It
will be visible under W=1 in case people want to go about fixing these
easily and enabling the warning treewide.

16536ce0df kconfig: fix broken dependency in randconfig-generated .config
[ Upstream commit c8fb7d7e48d11520ad24808cfce7afb7b9c9f798 ]

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")

Fix the above problems by allowing only selected reloc types in

c093b585da BACKPORT: kcov: test compiler capability in Kconfig and correct dependency
Work around missing cc-option support in Kconfig by checking required
compiler flags in Makefile.

(Upstream commit 5aadfdeb8de001ca04d500586e3b033404c28617.)

As Documentation/kbuild/kconfig-language.txt notes, 'select' should be
be used with care - it forces a lower limit of another symbol, ignoring
the dependency.  Currently, KCOV can select GCC_PLUGINS even if arch
does not select HAVE_GCC_PLUGINS.  This could cause the unmet direct
dependency.

Now that Kconfig can test compiler capability, let's handle this in a
more sophisticated way.

There are two ways to enable KCOV; use the compiler that natively
supports -fsanitize-coverage=trace-pc, or build the SANCOV plugin if
the compiler has ability to build GCC plugins.  Hence, the correct
dependency for KCOV is:

  depends on CC_HAS_SANCOV_TRACE_PC || GCC_PLUGINS

You do not need to build the SANCOV plugin if the compiler already
supports -fsanitize-coverage=trace-pc.  Hence, the select should be:

  select GCC_PLUGIN_SANCOV if !CC_HAS_SANCOV_TRACE_PC

With this, GCC_PLUGIN_SANCOV is selected only when necessary, so
scripts/Makefile.gcc-plugins can be cleaner.

I also cleaned up Kconfig and scripts/Makefile.kcov as well.

0f0fe8e7a5 UPSTREAM: gcc-plugins: fix build condition of SANCOV plugin
(Upstream commit 642ef99be932c4071274b28eaf3d3d85bbb6e78c.)

Since commit d677a4d60193 ("Makefile: support flag
-fsanitizer-coverage=trace-cmp"), you miss to build the SANCOV
plugin under some circumstances.

  CONFIG_KCOV=y
  CONFIG_KCOV_ENABLE_COMPARISONS=y
  Your compiler does not support -fsanitize-coverage=trace-pc
  Your compiler does not support -fsanitize-coverage=trace-cmp

Under this condition, $(CFLAGS_KCOV) is not empty but contains a
space, so the following ifeq-conditional is false.

    ifeq ($(CFLAGS_KCOV),)

Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to
gcc-plugin-y while the SANCOV plugin is necessary as an alternative
means.

16b9c5c49b kconfig: don't crash on NULL expressions in expr_eq()
[ Upstream commit 272a72103012862e3a24ea06635253ead0b6e808 ]

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.

a06d07dd52 scripts/kallsyms: fix definitely-lost memory leak
[ Upstream commit 21915eca088dc271c970e8351290e83d938114ac ]

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

toolchain for RISC-V, the following modpost warning appeared:

----
WARNING: vmlinux.o(.data+0x19b10): Section mismatch in reference from the variable .LANCHOR1 to the function .init.text:sifive_serial_console_setup()
The variable .LANCHOR1 references
the function __init sifive_serial_console_setup()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
----

".LANCHOR1" is an ELF local symbol, automatically created by gcc's section
anchor generation code:

https://gcc.gnu.org/onlinedocs/gccint/Anchored-Addresses.html

https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/varasm.c;h=cd9591a45617464946dcf9a126dde277d9de9804;hb=9fb89fa845c1b2e0a18d85ada0b077c84508ab78#l7473

This was verified by compiling the kernel with -fno-section-anchors
and observing that the ".LANCHOR1" ELF local symbol disappeared, and
modpost no longer warned about the section mismatch.  The serial
driver code idiom triggering the warning is standard Linux serial
driver practice that has a specific whitelist inclusion in modpost.c.

I'm neither a modpost nor an ELF expert, but naively, it doesn't seem
useful for modpost to report section mismatch warnings caused by ELF
local symbols by default.  Local symbols have compiler-generated
names, and thus bypass modpost's whitelisting algorithm, which relies
on the presence of a non-autogenerated symbol name.  This increases
the likelihood that false positive warnings will be generated (as in
the above case).

Thus, disable section mismatch reporting on ELF local symbols.  The
rationale here is similar to that of commit 2e3a10a155 ("ARM: avoid
ARM binutils leaking ELF local symbols") and of similar code already
present in modpost.c:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/mod/modpost.c?h=v4.19-rc4&id=7876320f88802b22d4e2daf7eb027dd14175a0f8#n1256

This third version of the patch implements a suggestion from Masahiro
Yamada <yamada.masahiro@socionext.com> to restructure the code as an
additional pattern matching step inside secref_whitelist(), and
further improves the patch description.

51042de030 ANDROID: kbuild: merge module sections with LTO
LLD always splits sections with LTO, which increases module sizes. This
change adds a linker script that merges the split sections in the final
module.

4ff705ab4d ANDROID: init: ensure initcall ordering with LTO
With LTO, the compiler doesn't necessarily obey link order for
initcalls, and the initcall variable needs to be globally unique
to avoid naming collisions.

In order to preserve the correct order, we add each variable
into its own section and generate a linker script (in
scripts/link-vmlinux.sh) to ensure the order remains correct.  We
also add a __COUNTER__ prefix to the name, so we can retain the
order of initcalls within each compilation unit, and __LINE__ to
make the names more unique.

2acd1714d0 scripts/gdb: fix debugging modules compiled with hot/cold partitioning
[ Upstream commit 8731acc5068eb3f422a45c760d32198175c756f8 ]

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.

37ce64502d scripts/setlocalversion: Improve -dirty check with git-status --no-optional-locks
[ Upstream commit ff64dd4857303dd5550faed9fd598ac90f0f2238 ]

git-diff-index does not refresh the index for you, so using it for a
"-dirty" check can give misleading results. Commit 6147b1cf19651
("scripts/setlocalversion: git: Make -dirty check more robust") tried to
fix this by switching to git-status, but it overlooked the fact that
git-status also writes to the .git directory of the source tree, which
is definitely not kosher for an out-of-tree (O=) build. That is getting
reverted.

Fortunately, git-status now supports avoiding writing to the index via
the --no-optional-locks flag, as of git 2.14. It still calculates an
up-to-date index, but it avoids writing it out to the .git directory.

So, let's retry the solution from commit 6147b1cf19651 using this new
flag first, and if it fails, we assume this is an older version of git
and just use the old git-diff-index method.

It's hairy to get the 'grep -vq' (inverted matching) correct by stashing
the output of git-status (you have to be careful about the difference
betwen "empty stdin" and "blank line on stdin"), so just pipe the output
directly to grep and use a regex that's good enough for both the
git-status and git-diff-index version.

bf08b76890 namespace: fix namespace.pl script to support relative paths
[ Upstream commit 82fdd12b95727640c9a8233c09d602e4518e71f7 ]

The namespace.pl script does not work properly if objtree is not set to
an absolute path. The do_nm function is run from within the find
function, which changes directories.

Because of this, appending objtree, $File::Find::dir, and $source, will
return a path which is not valid from the current directory.

This used to work when objtree was set to an absolute path when using
"make namespacecheck". It appears to have not worked when calling
./scripts/namespace.pl directly.

This behavior was changed in 7e1c04779e ("kbuild: Use relative path
for $(objtree)", 2014-05-14)

Rather than fixing the Makefile to set objtree to an absolute path, just
fix namespace.pl to work when srctree and objtree are relative. Also fix
the script to use an absolute path for these by default.

Use the File::Spec module for this purpose. It's been part of perl
5 since 5.005.

The curdir() function is used to get the current directory when the
objtree and srctree aren't set in the environment.

rel2abs() is used to convert possibly relative objtree and srctree
environment variables to absolute paths.

Finally, the catfile() function is used instead of string appending
paths together, since this is more robust when joining paths together.

f41f00e95e randstruct: Check member structs in is_pure_ops_struct()
commit 60f2c82ed20bde57c362e66f796cf9e0e38a6dbb upstream.

While no uses in the kernel triggered this case, it was possible to have
a false negative where a struct contains other structs which contain only
function pointers because of unreachable code in is_pure_ops_struct().

b53ba116d6 scripts/decode_stacktrace: match basepath using shell prefix operator, not regex
[ Upstream commit 31013836a71e07751a6827f9d2ad41ef502ddaff ]

The basepath may contain special characters, which would confuse the regex
matcher.  ${var#prefix} does the right thing.

[ Upstream commit cb4819934a7f9b87876f11ed05b8624c0114551b ]

KBUILD_EXTRA_SYMBOLS makes sense only when building external modules.
Moreover, the modpost sets 'external_module' if the -e option is given.

I replaced $(patsubst %, -e %,...) with simpler $(addprefix -e,...)
while I was here.

32797c9105 kallsyms: exclude kasan local symbols on s390
[ Upstream commit 33177f01ca3fe550146bb9001bec2fd806b2f40c ]

gcc asan instrumentation emits the following sequence to store frame pc
when the kernel is built with CONFIG_RELOCATABLE:
debug/vsprintf.s:
        .section        .data.rel.ro.local,"aw"
        .align  8
.LC3:
        .quad   .LASANPC4826@GOTOFF
.text
        .align  8
        .type   number, @function
number:
.LASANPC4826:

and in case reloc is issued for LASANPC label it also gets into .symtab
with the same address as actual function symbol:
$ nm -n vmlinux | grep 0000000001397150
0000000001397150 t .LASANPC4826
0000000001397150 t number

In the end kernel backtraces are almost unreadable:

Since LASANPC labels are not even unique and get into .symtab only due
to relocs filter them out in kallsyms.

Looking at the relocation records in __mcount_loc shows a few spurious
entries:

  RELOCATION RECORDS FOR [__mcount_loc]:
  OFFSET           TYPE              VALUE
  0000000000000000 R_PPC64_ADDR64    .text.unlikely+0x0000000000000008

  0000000000000028 R_PPC64_ADDR64    .init.text+0x0000000000000014

The first entry in each section is incorrect. Looking at the
relocation records, the spurious entries correspond to the
R_PPC64_ENTRY records:

  RELOCATION RECORDS FOR [.text.unlikely]:
  OFFSET           TYPE              VALUE
  0000000000000000 R_PPC64_REL64     .TOC.-0x0000000000000008

  0000000000000014 R_PPC64_REL24     _mcount
  <snip>

The problem is that we are not validating the return value from
get_mcountsym() in sift_rel_mcount(). With this entry, mcountsym is 0,
but Elf_r_sym(relp) also ends up being 0. Fix this by ensuring
mcountsym is valid before processing the entry.

e3ea178cf1 BACKPORT: kasan: remove use after scope bugs detection.
Upstream commit 7771bdbbfd3d6f204631b6fd9e1bbc30cd15918e.

Use after scope bugs detector seems to be almost entirely useless for
the linux kernel.  It exists over two years, but I've seen only one
valid bug so far [1].  And the bug was fixed before it has been
reported.  There were some other use-after-scope reports, but they were
false-positives due to different reasons like incompatibility with
structleak plugin.

This feature significantly increases stack usage, especially with GCC <
9 version, and causes a 32K stack overflow.  It probably adds
performance penalty too.

Given all that, let's remove use-after-scope detector entirely.

While preparing this patch I've noticed that we mistakenly enable
use-after-scope detection for clang compiler regardless of
CONFIG_KASAN_EXTRA setting.  This is also fixed now.

b6029bd949 BACKPORT: kasan: turn off asan-stack for clang-8 and earlier
Upstream commit 6baec880d7a53cbc2841123e56ee31e830df9b49.

Building an arm64 allmodconfig kernel with clang results in over 140
warnings about overly large stack frames, the worst ones being:

  drivers/gpu/drm/panel/panel-sitronix-st7789v.c:196:12: error: stack frame size of 20224 bytes in function 'st7789v_prepare'
  drivers/video/fbdev/omap2/omapfb/displays/panel-tpo-td028ttec1.c:196:12: error: stack frame size of 13120 bytes in function 'td028ttec1_panel_enable'
  drivers/usb/host/max3421-hcd.c:1395:1: error: stack frame size of 10048 bytes in function 'max3421_spi_thread'
  drivers/net/wan/slic_ds26522.c:209:12: error: stack frame size of 9664 bytes in function 'slic_ds26522_probe'
  drivers/crypto/ccp/ccp-ops.c:2434:5: error: stack frame size of 8832 bytes in function 'ccp_run_cmd'
  drivers/media/dvb-frontends/stv0367.c:1005:12: error: stack frame size of 7840 bytes in function 'stv0367ter_algo'

None of these happen with gcc today, and almost all of these are the
result of a single known issue in llvm.  Hopefully it will eventually
get fixed with the clang-9 release.

In the meantime, the best idea I have is to turn off asan-stack for
clang-8 and earlier, so we can produce a kernel that is safe to run.

I have posted three patches that address the frame overflow warnings
that are not addressed by turning off asan-stack, so in combination with
this change, we get much closer to a clean allmodconfig build, which in
turn is necessary to do meaningful build regression testing.

It is still possible to turn on the CONFIG_ASAN_STACK option on all
versions of clang, and it's always enabled for gcc, but when
CONFIG_COMPILE_TEST is set, the option remains invisible, so
allmodconfig and randconfig builds (which are normally done with a
forced CONFIG_COMPILE_TEST) will still result in a mostly clean build.

8a94e7d158 BACKPORT: kasan: add CONFIG_KASAN_GENERIC and CONFIG_KASAN_SW_TAGS
Upstream commit 2bd926b439b4cb6b9ed240a9781cd01958b53d85.
There were a couple of issues during backport.
The first one is caused by the upstream commit using cc-option in Kconfig,
which android kernel doesn't support. Instead of using cc-option, this
backport moves the compiler check to the Makefile.
The other one is that older GCCs (before version 5) don't support the
__has_attribute macro. The upstream has dealt with this via a special
header file (compiler_attributes.h) that emulates this macro for some
cases. Instead of backporting the whole series that adds this header do
a direct GCC version check to determine the presense of the
no_sanitize_address attribute.

This commit splits the current CONFIG_KASAN config option into two:
1. CONFIG_KASAN_GENERIC, that enables the generic KASAN mode (the one
   that exists now);
2. CONFIG_KASAN_SW_TAGS, that enables the software tag-based KASAN mode.

The name CONFIG_KASAN_SW_TAGS is chosen as in the future we will have
another hardware tag-based KASAN mode, that will rely on hardware memory
tagging support in arm64.

With CONFIG_KASAN_SW_TAGS enabled, compiler options are changed to
instrument kernel files with -fsantize=kernel-hwaddress (except the ones
for which KASAN_SANITIZE := n is set).

Both CONFIG_KASAN_GENERIC and CONFIG_KASAN_SW_TAGS support both
CONFIG_KASAN_INLINE and CONFIG_KASAN_OUTLINE instrumentation modes.

This commit also adds empty placeholder (for now) implementation of
tag-based KASAN specific hooks inserted by the compiler and adjusts
common hooks implementation.

While this commit adds the CONFIG_KASAN_SW_TAGS config option, this option
is not selectable, as it depends on HAVE_ARCH_KASAN_SW_TAGS, which we will
enable once all the infrastracture code has been added.

86eab9d124 UPSTREAM: kasan: support alloca() poisoning
Upstream commit 342061ee4ef3d80001d1ae494378f3979c861dba.

clang's AddressSanitizer implementation adds redzones on either side of
alloca()ed buffers.  These redzones are 32-byte aligned and at least 32
bytes long.

__asan_alloca_poison() is passed the size and address of the allocated
buffer, *excluding* the redzones on either side.  The left redzone will
always be to the immediate left of this buffer; but AddressSanitizer may
need to add padding between the end of the buffer and the right redzone.
If there are any 8-byte chunks inside this padding, we should poison
those too.

__asan_allocas_unpoison() is just passed the top and bottom of the dynamic
stack area, so unpoisoning is simpler.

Upstream commit 1a69e7ce8391a8bc808baf04e06d88ab4024ca47.

LLVM doesn't understand GCC-style paramters ("--param asan-foo=bar"), thus
we currently we don't use inline/globals/stack instrumentation when
building the kernel with clang.

Add support for LLVM-style parameters ("-mllvm -asan-foo=bar") to enable
all KASAN features.

793ff5efee scripts/decode_stacktrace.sh: prefix addr2line with $CROSS_COMPILE
[ Upstream commit c04e32e911653442fc834be6e92e072aeebe01a1 ]

At least for ARM64 kernels compiled with the crosstoolchain from
Debian/stretch or with the toolchain from kernel.org the line number is
not decoded correctly by 'decode_stacktrace.sh':

  $ echo "[  136.513051]  f1+0x0/0xc [kcrash]" | \
    CROSS_COMPILE=/opt/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- \
   ./scripts/decode_stacktrace.sh /scratch/linux-arm64/vmlinux \
                                  /scratch/linux-arm64 \
                                  /nfs/debian/lib/modules/4.20.0-devel
  [  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:68) kcrash

If addr2line from the toolchain is used the decoded line number is correct:

  [  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:57) kcrash

4fea6066fb scripts/checkstack.pl: Fix arm64 wrong or unknown architecture
[ Upstream commit 4f45d62a52297b10ded963412a158685647ecdec ]

The following error occurs for the `make ARCH=arm64 checkstack` case:

aarch64-linux-gnu-objdump -d vmlinux $(find . -name '*.ko') | \
perl ./scripts/checkstack.pl arm64
wrong or unknown architecture "arm64"

As suggested by Masahiro Yamada, fix the above error using regular
expressions in the same way it was fixed for the `ARCH=x86` case via
commit fda9f9903b ("scripts/checkstack.pl: automatically handle
32-bit and 64-bit mode for ARCH=x86").
