The lexer has conventionally associated kconf_id data with yylval
to carry additional information to the parser.

There is no grammatical ambiguity by using T_WORD for variables.
The parser can distinguish variables from symbols from the context.

Currently, the lexer returns T_ASSIGN for all of =, :=, and +=
associating yylval with the flavor.
I want to make the generated lexer as simple as possible. So, the
lexer should convert keywords to tokens without thinking about the
meaning.
= -> T_EQUAL
:= -> T_COLON_EQUAL
+= -> T_PLUS_EQUAL
Unfortunately, Kconfig uses = instead of == for the equal operator.
So, the same token T_EQUAL is used for assignment and comparison.
The parser can still distinguish them from the context.

For the keywords "modules", "defconfig_list", and "allnoconfig_y",
the lexer should pass specific tokens instead of generic T_WORD.
This simplifies both the lexer and the parser.

The LLVM/Clang project provides many tools for analyzing C source code.
Many of these tools are based on LibTooling
(https://clang.llvm.org/docs/LibTooling.html), which depends on a
database of compiler flags. The standard container for this database is
compile_commands.json, which consists of a list of JSON objects, each
with "directory", "file", and "command" fields.
Some build systems, like cmake or bazel, produce this compilation
information directly. Naturally, Makefiles don't. However, the kernel
makefiles already create .<target>.o.cmd files that contain all the
information needed to build a compile_commands.json file.
So, this commit adds scripts/gen_compile_commands.py, which recursively
searches through a directory for .<target>.o.cmd files and extracts
appropriate compile commands from them. It writes a
compile_commands.json file that LibTooling-based tools can use.
By default, gen_compile_commands.py starts its search in its working
directory and (over)writes compile_commands.json in the working
directory. However, it also supports --output and --directory flags for
out-of-tree use.
Note that while gen_compile_commands.py enables the use of clang-based
tools, it does not require the kernel to be compiled with clang. E.g.,
the following sequence of commands produces a compile_commands.json file
that works correctly with LibTooling.
make defconfig
make
scripts/gen_compile_commands.py
Also note that this script is written to work correctly in both Python 2
and Python 3, so it does not specify the Python version in its first
line.
For an example of the utility of this script: after running
gen_compile_commands.json on the latest kernel version, I was able to
use Vim + the YouCompleteMe pluging + clangd to automatically jump to
definitions and declarations. Obviously, cscope and ctags provide some
of this functionality; the advantage of supporting LibTooling is that it
opens the door to many other clang-based tools that understand the code
directly and do not rely on regular expressions and heuristics.
Tested: Built several recent kernel versions and ran the script against
them, testing tools like clangd (for editor/LSP support) and clang-check
(for static analysis). Also extracted some test .cmd files from a kernel
build and wrote a test script to check that the script behaved correctly
with all permutations of the --output and --directory flags.

Currently, "visible" and "depends on", if defined in a menu entry,
must appear in that order.
The real example is in drivers/media/tuners/Kconfig:
menu "Customize TV tuners"
visible if <expr1>
depends on <expr2>
... is fine, but you cannot change the property order like this:
menu "Customize TV tuners"
depends on <expr2>
visible if <expr1>
Kconfig does not require a specific order of properties. In this case,
menu_add_visibility(() and menu_add_dep() are orthogonal.

This commit decreases 6 shift/reduce conflicts, and finally achieves
conflict-free parser.
Since Kconfig has no terminator for a config block, detecting the end
of config_stmt is not easy.
For example, there are two ways for handling the error in the following
code:
1 config FOO
2 =
[A] Print "unknown option" error, assuming the line 2 is a part of
config_option_list
[B] Print "invalid statement", assuming the line 1 is reduced into
a config_stmt by itself
Bison actually chooses [A] because it performs the shift rather than
the reduction where both are possible.
However, there is no reason to choose one over the other.
Let's remove the option_error, and let it fall back to [B].

This commit decreases 15 shift/reduce conflicts.
The location of this error recovery is ambiguous.
For example, there are two ways to interpret the following code:
1 config FOO
2 bool "foo"
[A] Both lines are reduced together into a config_stmt.
[B] The only line 1 is reduced into a config_stmt, and the line 2
matches to "option_name error T_EOL"
Of course, we expect [A], but [B] could be grammatically possible.
Kconfig has no terminator for a config block. So, we cannot detect its
end until we see a non-property keyword. People often insert a blank
line between two config blocks, but it is just a coding convention.
Blank lines are actually allowed anywhere in Kconfig files.
The real error is when a property keyword appears right after "endif",
"endchoice", "endmenu", "source", "comment", or variable assignment.
Instead of fixing the grammatical ambiguity, I chose to simply remove
this error recovery.
The difference is
unexpected option "bool"
... is turned into a more generic message:
invalid statement

It would be nice to warn if a new line is missing at end of file.
We could do this by checkpatch.pl for arbitrary files, but new line
is rather essential as a statement terminator in Kconfig.
The warning message looks like this:
kernel/Kconfig.preempt:60:warning: no new line at end of file
Currently, kernel/Kconfig.preempt is the only file with no new line
at end of file. Fix it.
I know there are some false negative cases. For example, no warning
is displayed when the last line contains some whitespaces/comments,
but no new line. Yet, this commit works well for most cases.

The spdxcheck script currently falls over when confronted with a binary
file (such as Documentation/logo.gif). To avoid that, always open files
in binary mode and decode line-by-line, ignoring encoding errors.
One tricky case is when piping data into the script and reading it from
standard input. By default, standard input will be opened in text mode,
so we need to reopen it in binary mode.
The breakage only happens with python3 and results in a
UnicodeDecodeError (according to Uwe).

There is actually a space after "sp," like this,
ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]!
Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space. Hence, it displays every stack as zero-size.
After this patch, checkpatch.pl is able to match the start of a
function's objdump, and is then able to calculate each function's stack
correctly.

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.
Check DT binding schema documents:
make dt_binding_check
Build dts files and check using DT binding schema:
make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

On ARM, we currently only change the value of the stack canary when
switching tasks if the kernel was built for UP. On SMP kernels, this
is impossible since the stack canary value is obtained via a global
symbol reference, which means
a) all running tasks on all CPUs must use the same value
b) we can only modify the value when no kernel stack frames are live
on any CPU, which is effectively never.
So instead, use a GCC plugin to add a RTL pass that replaces each
reference to the address of the __stack_chk_guard symbol with an
expression that produces the address of the 'stack_canary' field
that is added to struct thread_info. This way, each task will use
its own randomized value.

This commit decreases 8 shift/reduce conflicts.
A certain amount of grammatical ambiguity comes from how to reduce
excessive T_EOL tokens.
Let's take a look at the example code below:
1 config A
2 bool "a"
3
4 depends on B
5
6 config B
7 def_bool y
The line 3 is melt into "config_option_list", but the line 5 can be
either a part of "config_option_list" or "common_stmt" by itself.
Currently, the lexer converts '\n' to T_EOL verbatim. In Kconfig,
a new line works as a statement terminator, but new lines in empty
lines are not critical since empty lines (or lines that contain only
whitespaces/comments) are just no-op.
If the lexer simply discards no-op lines, the parser will not be
bothered by excessive T_EOL tokens.
Of course, this means we are shifting the complexity from the parser
to the lexer, but it is much easier than tackling on shift/reduce
conflicts.
I introduced the second stage lexer to tweak the behavior.
Discard T_EOL if the previous token is T_EOL or T_HELPTEXT.
Two T_EOL tokens in a row is meaningless. T_HELPTEXT is a special
token that is reduced without T_EOL.

Here, similar matching patters are duplicated in order to look ahead
the '\n' character. If the next character is '\n', the lexer returns
T_WORD_QUOTE because it must be prepared to return T_EOL at the next
match.

An unterminated string literal followed by new line is passed to the

Currently, warn_ignore_character() displays invalid file name and
line number.
The lexer should use current_file->name and yylineno, while the parser
should use zconf_curname() and zconf_lineno().
This difference comes from that the lexer is always going ahead
of the parser. The parser needs to look ahead one token to make a
shift/reduce decision, so the lexer is requested to scan more text
from the input file.
This commit fixes the warning message from warn_ignored_character().

Please, use at least K&R C; printf had been able to left-adjust
a field for as long as stdio existed and use of '*' for variable

you are using a much later feature of the language than that -
in K&R C
static char *stoupperx(const char *s)

would've been spelled as
static char *stoupperx(s)
char *s;

When building with -ffunction-sections, the compiler will place each
function into its own ELF section, prefixed with ".text". For example,
a simple test module with functions test_module_do_work() and
test_module_wq_func():
% objdump --section-headers test_module.o | awk '/\.text/{print $2}'
.text
.text.test_module_do_work
.text.test_module_wq_func
.init.text
.exit.text
Adjust the recordmcount scripts to look for ".text" as a section name
prefix. This will ensure that those functions will be included in the

The S_OTHER type could be set only when conf_read_simple() is reading
include/config/auto.conf file.
For example, CONFIG_FOO=y exists in include/config/auto.conf but it is
missing from the currently parsed Kconfig files, sym_lookup() allocates
a new symbol, and sets its type to S_OTHER.
Strangely, it will be set to S_STRING by conf_set_sym_val() a few lines
below while it is obviously bool or tristate type. On the other hand,
when CONFIG_BAR="bar" is being dropped from include/config/auto.conf,
its type remains S_OTHER. Because for_all_symbols() omits S_OTHER
symbols, conf_touch_deps() misses to touch include/config/bar.h
This behavior has been a pretty mystery for me, and digging the git
histroy did not help. At least, touching depfiles is broken for string
type symbols.
I removed S_OTHER entirely, and reimplemented it more simply.
If CONFIG_FOO was visible in the previous syncconfig, but is missing
now, what we want to do is quite simple; just call conf_touch_dep()
to touch include/config/foo.h instead of allocating a new symbol data.

In commit 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and

... which agrees with the policy of Kbuild.
Let's move it to scripts/Kbuild.include, with no prerequisites.
Note:
If an intermediate file is generated by $(call if_changed,...), you
still need to add it to "targets" so its .*.cmd file is included.
The arm/arm64 crypto files are generated by $(call cmd,shipped),
so they do not need to be added to "targets", but need to be added
to "clean-files" so "make clean" can properly clean them away.
