Currently script uses Perl to get the machine architecture. This can be
erroneous since Perl uses the architecture of the machine that Perl was
compiled on not the architecture of the running machine. We should use
the systems `uname` command instead.
Use `uname -m` instead of Perl to get the machine architecture.

Currently script only supports 4 page table levels because of the way
the kernel address regular expression is crafted. We can do better than
this. Using previously added support for kernel configuration options we
can get the number of page table levels defined by
CONFIG_PGTABLE_LEVELS. Using this value a correct regular expression can
be crafted. This only supports 5 page tables on x86_64.
Add support for 5 page table levels on x86_64.

Features that rely on the ability to get kernel configuration options
are ready to be implemented in script. In preparation for this we can
add support for kernel config options as a separate patch to ease
review.
Add support for locating and parsing kernel configuration file.

Currently script checks only first and last address in the vsyscall
memory range. We can do better than this. When checking for false
positives against $match, we can convert $match to a hexadecimal value
then check if it lies within the range of vsyscall addresses.
Check whole range of vsyscall addresses when checking for false
positive.

A number of the command line options to script are dependant on the
option --input-raw being set. If we indent these options it makes
explicit this dependency.

Pull RISC-V updates from Palmer Dabbelt:
"This contains the new features we'd like to incorporate into the
RISC-V port for 4.17. We might have a bit more stuff land later in the
merge window, but I wanted to get this out earlier just so everyone
can see where we currently stand.
A short summary of the changes is:
- We've added support for dynamic ftrace on RISC-V targets.
- There have been a handful of cleanups to our atomic and locking
routines. They now more closely match the released RISC-V memory
model draft.
- Our module loading support has been cleaned up and is now enabled
by default, despite some limitations still existing.
- A patch to define COMMANDLINE_FORCE instead of COMMANDLINE_OVERRIDE
so the generic device tree code picks up handling all our command
line stuff.
There's more information in the merge commits for each patch set"

Pull arm64 updates from Will Deacon:
"Nothing particularly stands out here, probably because people were
tied up with spectre/meltdown stuff last time around. Still, the main
pieces are:
- Rework of our CPU features framework so that we can whitelist CPUs
that don't require kpti even in a heterogeneous system
- Support for the IDC/DIC architecture extensions, which allow us to
elide instruction and data cache maintenance when writing out
instructions
- Removal of the large memory model which resulted in suboptimal
codegen by the compiler and increased the use of literal pools,
which could potentially be used as ROP gadgets since they are
mapped as executable
- Rework of forced signal delivery so that the siginfo_t is
well-formed and handling of show_unhandled_signals is consolidated
and made consistent between different fault types
- More siginfo cleanup based on the initial patches from Eric
Biederman

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"

Since commit 28128c61e08e ("kconfig.h: Include compiler types to avoid
missed struct attributes"), <linux/kconfig.h> pulls in kernel-space
headers to unrelated places.
Commit 0f9da844d877 ("MIPS: boot: Define __ASSEMBLY__ for its.S build")
suppress the build error by defining __ASSEMBLY__, but ITS (i.e. DTS)
is not assembly, and should not include <linux/compiler_types.h> in the

Looking at arch/s390/tools/Makefile, host programs gen_facilities and
gen_opcode_table now pull in <linux/compiler_types.h> as well.
The motivation for that commit was to define necessary attributes
before any struct is defined. Obviously, this happens only in C.
It is enough to include <linux/compiler_types.h> only when compiling
C files, and only when compiling kernel space. Move the include to
c_flags.

This changes security_hook_heads to use hlist_heads instead of
the circular doubly-linked list heads. This should cut down
the size of the struct by about half.
In addition, it allows mutation of the hooks at the tail of the
callback list without having to modify the head. The longer-term
purpose of this is to enable making the heads read only.

There is a change in how command line parsing is done in this version.
Excludes and includes are now ordered with the file list. Since
the spec file puts the file list before the exclude list it means newer
tar ignores the excludes and packs all the build output into the
kernel-devel RPM resulting in a huge package.
Simple argument re-ordering fixes the problem.

Tracking the line number by hand is error-prone since you need to
increment it in every \n matching pattern.
If '%option yylineno' is set, flex defines 'yylineno' to contain the
current line number and automatically updates it each time it reads a
\n character. This is much more convenient although the lexer does
not initializes yylineno, so you need to set it to 1 each time you
start reading a new file, and restore it you go back to the previous
file.
I tested this with DEBUG_PARSE, and confirmed the same dump message
was produced.
I removed the perf-report option. Otherwise, I see the following
message:
%option yylineno entails a performance penalty ONLY on rules that
can match newline characters

Currently, the recursive inclusion is not detected when the offending
file is about to be included; it is detected the offending file is

Currently, the unmet dependency warnings end up with endlessly long
expressions, most of which are false positives.
Here is test code to demonstrate how it currently works.
[Test Case]
config DEP1
def_bool y
config DEP2
bool "DEP2"
config A
bool "A"
select E
config B
bool "B"
depends on DEP2
select E
config C
bool "C"
depends on DEP1 && DEP2
select E
config D
def_bool n
select E
config E
bool
depends on DEP1 && DEP2
[Result]
$ make config

*
DEP2 (DEP2) [N/y/?] (NEW) n
A (A) [N/y/?] (NEW) y
warning: (A && B && D) selects E which has unmet direct
dependencies (DEP1 && DEP2)
Here, I see some points to be improved.
First, '(A || B || D)' would make more sense than '(A && B && D)'.
I am not sure if this is intentional, but expr_simplify_unmet_dep()
turns OR expressions into AND, like follows:
case E_OR:
return expr_alloc_and(
Second, we see false positives. 'A' is a real unmet dependency.
'B' is false positive because 'DEP1' is fixed to 'y', and 'B' depends
on 'DEP2'. 'C' was correctly dropped by expr_simplify_unmet_dep().
'D' is also false positive because it has no chance to be enabled.
Current expr_simplify_unmet_dep() cannot avoid those false positives.
After all, I decided to use the same helpers as used for printing
reverse dependencies in the help.
With this commit, unreadable warnings (most of the reported symbols are
false positives) in the real world:

Commit 246cf9c26bf1 ("kbuild: Warn on selecting symbols with unmet
direct dependencies") forcibly promoted ->dir_dep.tri to yes from mod.
So, the unmet direct dependencies of tristate symbols are not reported.
[Test Case]
config MODULES
def_bool y
option modules
config A
def_bool y
select B
config B
tristate "B"
depends on m
This causes unmet dependency because 'B' is forced 'y' ignoring
'depends on m'. This should be warned.
On the other hand, the following case ('B' is bool) should not be
warned, so 'depends on m' for bool symbols should be naturally treated
as 'depends on y'.
[Test Case2 (not unmet dependency)]
config MODULES
def_bool y

config A
def_bool y
select B
config B

Commit 3b9a19e08960 ("kconfig: loop as long as we changed some symbols

Prior to that commit, the sub-choice values were not set.
I am not sure whether this is an intended feature or just something
people discovered works, but it is used in the real world;
drivers/usb/gadget/legacy/Kconfig is source'd in a choice context,
then creates a sub-choice in it.
For the test case in this commit, there are 3 possible results.
Case 1:
CONFIG_A=y
# CONFIG_B is not set
Case 2:
# CONFIG_A is not set
CONFIG_B=y
CONFIG_C=y
# CONFIG_D is not set
Case 3:
# CONFIG_A is not set

# CONFIG_C is not set

either of the three.

Commit fbe98bb9ed3d ("kconfig: Fix defconfig when one choice menu
selects options that another choice menu depends on") fixed defconfig
when two choices interact (i.e. calculating the visibility of a choice
requires to calculate another choice).
The test code in that commit log was based on the real world example,
and complicated. So, I shrunk it down to the following:
defconfig.choice:
---8<---
CONFIG_CHOICE_VAL0=y
---8<---
---8<---
config MODULES
def_bool y
option modules
choice
prompt "Choice"
config CHOICE_VAL0
tristate "Choice 0"
config CHOICE_VAL1
tristate "Choice 1"
endchoice
choice
prompt "Another choice"
depends on CHOICE_VAL0
config DUMMY
bool "dummy"
endchoice
---8<---
Prior to commit fbe98bb9ed3d,
$ scripts/kconfig/conf --defconfig=defconfig.choice Kconfig.choice
resulted in:
CONFIG_MODULES=y
CONFIG_CHOICE_VAL0=m
# CONFIG_CHOICE_VAL1 is not set
CONFIG_DUMMY=y
where the expected result would be:
CONFIG_MODULES=y
CONFIG_CHOICE_VAL0=y
# CONFIG_CHOICE_VAL1 is not set
CONFIG_DUMMY=y
Roughly, this weird behavior happened like this:
Symbols are calculated a couple of times. First, all symbols are
calculated in conf_read(). The first 'choice' is evaluated to 'y'
due to the SYMBOL_DEF_USER flag, but sym_calc_choice() clears it
unless all of its choice values are explicitly set by the user.
conf_set_all_new_symbols() clears all SYMBOL_VALID flags. Then, only
choices are calculated. Here, the SYMBOL_DEF_USER for the first choice
has been forgotten, so it is evaluated to 'm'. set_all_choice_values()
sets SYMBOL_DEF_USER again to choice symbols.
When calculating the second choice, due to 'depends on CHOICE_VAL0',
it triggers the calculation of CHOICE_VAL0. As a result, SYMBOL_VALID
is set for CHOICE_VAL0.
Symbols except choices get the final chance of re-calculation in
conf_write(). In a normal case, CHOICE_VAL0 would be re-calculated,
then the first choice would be indirectly re-calculated with the
SYMBOL_DEF_USER which has been recalled by set_all_choice_values(),
which would be evaluated to 'y'. But, in this case, CHOICE_VAL0 has
already been marked as SYMBOL_VALID, so this re-calculation does not
happen. Then, =m from the conf_set_all_new_symbols() phase is written
out to the .config file.
Add a unit test for this naive case.

Many parts in Kconfig are so cryptic and need refactoring. However,
its complexity prevents us from moving forward. There are several
naive corner cases where it is difficult to notice breakage. If
those are covered by unit tests, we will be able to touch the code
with more confidence.
Here is a simple test framework based on pytest. The conftest.py
provides a fixture useful to run commands such as 'oldaskconfig' etc.
and to compare the resulted .config, stdout, stderr with expectations.
How to add test cases?
----------------------
For each test case, you should create a subdirectory under
scripts/kconfig/tests/ (so test cases are separated from each other).
Every test case directory should contain the following files:
- __init__.py: describes test functions
- Kconfig: the top level Kconfig file for the test
To do a useful job, test cases generally need additional data like
input .config and information about expected results.
How to run tests?
-----------------
You need python3 and pytest. Then, run "make testconfig". O= option
is supported. If V=1 is given, detailed logs captured during tests
are displayed.

Historically, "make oldconfig" has changed its behavior several times,
quieter or louder. (I attached the history below.) Currently, it is
not as quiet as it should be. This commit addresses it.
Test Case
---------
---------------------------(Kconfig)----------------------------
menu "menu"
config FOO
bool "foo"
menu "sub menu"
config BAR
bool "bar"
endmenu
endmenu
menu "sibling menu"
config BAZ
bool "baz"
endmenu
----------------------------------------------------------------
---------------------------(.config)----------------------------
CONFIG_BAR=y
CONFIG_BAZ=y
----------------------------------------------------------------
With the Kconfig and .config above, "make silentoldconfig" and
"make oldconfig" work differently, like follows:
$ make silentoldconfig
scripts/kconfig/conf --silentoldconfig Kconfig
*
* Restart config...
*
*
* menu
*
foo (FOO) [N/y/?] (NEW) y
#
# configuration written to .config
#
$ make oldconfig
scripts/kconfig/conf --oldconfig Kconfig
*
* Restart config...
*
*
* menu
*
foo (FOO) [N/y/?] (NEW) y
*
* sub menu
*
bar (BAR) [Y/n/?] y
#
# configuration written to .config
#
Both hide "sibling node" since it is irrelevant. The difference is
that silentoldconfig hides "sub menu" whereas oldconfig does not.
The behavior of silentoldconfig is preferred since the "sub menu"
does not contain any new symbol.
The root cause is in conf(). There are three input modes that can
call conf(); oldaskconfig, oldconfig, and silentoldconfig.
Everytime conf() encounters a menu entry, it calls check_conf() to
check if it contains new symbols. If no new symbol is found, the
menu is just skipped.
Currently, this happens only when input_mode == silentoldconfig.
The oldaskconfig enters into the check_conf() loop as silentoldconfig,
so oldaskconfig works likewise for the second loop or later, but it
never happens for oldconfig. So, irrelevant sub-menus are shown for
oldconfig.
Change the test condition to "input_mode != oldaskconfig". This is
false only for the first loop of oldaskconfig; it must ask the user
all symbols, so no need to call check_conf().
History of oldconfig
--------------------
[0] Originally, "make oldconfig" was as loud as "make config" (It
showed the entire .config file)
[1] Commit cd9140e1e73a ("kconfig: make oldconfig is now less chatty")
made oldconfig quieter, but it was still less quieter than
silentoldconfig. (oldconfig did not hide sub-menus)
[2] Commit 204c96f60904 ("kconfig: fix silentoldconfig") changed
the input_mode of oldconfig to "ask_silent" from "ask_new".
So, oldconfig really became as quiet as silentoldconfig.
(oldconfig hided irrelevant sub-menus)
[3] Commit 4062f1a4c030 ("kconfig: use long options in conf") made
oldconfig as loud as [0] due to misconversion.
[4] Commit 14828349719a ("kconfig: fix make oldconfig") addressed
the misconversion of [3], but it made oldconfig quieter only to
the same level as [1], not [2].
This commit is restoring the behavior of [2].
