The 'shell' built-in only returns the first 256 bytes of the command's
output. In some cases, 'shell' is used to return a path; by bumping up
the buffer size to 4096 this lets us capture up to PATH_MAX.
The specific case where I ran into this was due to commit 1e860048c5
("gcc-plugins: simplify GCC plugin-dev capability test"). After this
change, we now use `$(shell,$(CC) -print-file-name=plugin)` to return
a path; if the gcc path is particularly long, then the path ends up
truncated at the 256 byte mark, which makes the HAVE_GCC_PLUGINS
depends test always fail.

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:
ACPI_CUSTOM_DSDT_FILE
ARC_BUILTIN_DTB_NAME
ARC_TUNE_MCPU
BUILTIN_DTB_SOURCE

When converting a modular kernel to a monolithic kernel, once the kernel

If this function fails to touch a dummy header due to missing parent
directory, then it creates it and touches the file again.
This was needed because CONFIG_FOO_BAR was previously tracked by
include/config/foo/bar.h. (include/config/foo/ may not exist here)
This is no longer the case since commit 0e0345b77a ("kbuild: redo

In Kconfig, like Python, you can enclose a string by double-quotes or
single-quotes. So, both "foo" and 'foo' are allowed.
The variable, "str", is used to remember whether the string started with
a double-quote or a single-quote because open/closing quotation marks
must match.
The name "str" is too generic to understand the intent. Rename it to
"open_quote", which is easier to understand. The type should be 'char'.

When one searches for a main menu item, links aren't created for it like
with the rest of the symbols.
This happens because we trace the item until we get to the rootmenu, but
we don't include it in the path of the item. The rationale was probably
that we don't want to show the main menu in the path of all items,
because it is redundant.
However, when an item has only the rootmenu in its path it should be
included, because this way the user can jump to its location.
Add a 'Main menu' entry in the 'Location:' section for the kconfig
items.
This makes the 'if (i > 0)' superfluous because each item with prompt
will have at least one menu in its path.

When merging configuration fragments, it might be of interest to

case any redefinition has been detected.
With strict mode, warnings are emitted as before, but the script
terminates with rc=1. If -y is set to define "builtin having
precedence over modules", fragments are still allowed to set =m (while
the base config has =y). Strict mode will tolerate that as demotions
from =y to =m are ignored when setting -y.

Patch series "streamline_config.pl: Fix Perl spacing".
Talking with John Hawley about how vim and emacs deal with Perl files with
respect to tabs and spaces, I found that some of my Perl code in the
kernel had inconsistent spacing. The way emacs handles Perl by default is
to use 4 spaces per indent, but make all 8 spaces into a single tab. Vim
does not do this by default. But if you add the vim variable control:
# vim: softtabstop=4
to a perl file, it makes vim behave the same way as emacs.
The first patch is to change all 8 spaces into a single tab (mostly from
people editing the file with vim). The next patch adds the softtabstop
variable to make vim act like emacs by default.
This patch (of 2):
As Perl code tends to have 4 space indentation, but uses tabs for every 8
spaces, make that consistent in the streamline_config.pl code. Replace
all 8 spaces with a single tab.

If the user selects the very first entry in a page and performs a
search-up operation, or selects the very last entry in a page and
performs a search-down operation that will not succeed (e.g., via
[/]asdfzzz[Up Arrow]), nconf will never terminate searching the page.
The reason is that in this case, the starting point will be set to -1
or n, which is then translated into (n - 1) (i.e., the last entry of
the page) or 0 (i.e., the first entry of the page) and finally the
search begins. This continues to work fine until the index reaches 0 or
(n - 1), at which point it will be decremented to -1 or incremented to
n, but not checked against the starting point right away. Instead, it's
wrapped around to the bottom or top again, after which the starting
point check occurs... and naturally fails.
My original implementation added another check for -1 before wrapping
the running index variable around, but Masahiro Yamada pointed out that
the actual issue is that the comparison point (starting point) exceeds
bounds (i.e., the [0,n-1] interval) in the first place and that,
instead, the starting point should be fixed.
This has the welcome side-effect of also fixing the case where the
starting point was n while searching down, which also lead to an
infinite loop.
OTOH, this code is now essentially all his work.
Amazingly, nobody seems to have been hit by this for 11 years - or at
the very least nobody bothered to debug and fix this.

This helper is the same as the sample code in the NCURSES HOWTO [1],
but it is over-engineering to be used for nconf.
I do not see any good reason to use the 'float' type just for the
division by 2.
All the call-sites pass a non-NULL pointer to the first argument,
so 'if (win == NULL) win = stdscr;' is dead code.
'if (startx != 0) x = startx;' is dead code because 'x' will be
overridden some lines below, by 'x = startx + (int)temp;'.
All the call-sites pass a non-zero value to the second argument,
so 'if (starty != 0)' is always true.
getyx(win, y, x) is also dead-code because both 'y' and 'x' are
overridden.
All the call-sites pass 0 to the third parameter, so 'startx' can
be removed.
All the call-sites pass a non-zero value to the fourth parameter,
so 'if (width == 0) width = 80;' is dead code.
The window will be refreshed later, so there is no need to call
refresh() in this function.
Change the type of the last parameter from 'chtype' to 'int' to be
aligned with the prototype, 'int wattrset(WINDOW *win, int attrs);'

A menu can be empty when all the options in it are hidden by unmet

menu "This menu will be empty"

bool "foo"
depends on BROKEN
endmenu
If you visit this menu and press a '/' key and then another key, nconf
crashes with:
Floating point exception (core dumped)
When the number of items is zero, it does not make sense to search in

Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one

"defconfig_list" is a weird option that defines a static symbol that
declares the list of base config files in case the .config does not
exist yet.
This is quite different from other normal symbols; we just abused the
"string" type and the "default" properties to list out the input files.
They must be fixed values since these are searched for and loaded in
the parse stage.
It is an ugly hack, and should not exist in the first place. Providing
this feature as an environment variable is a saner approach.

This function is only used in conf.c. Move it there together with the
randomize_choice_values() helper.
Define 'enum conf_def_mode' locally in conf.c as well.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
The current option parse code is clumsy.
The 's' option is separately handled in an if-conditional due to the
following code:
input_mode = (enum input_mode)opt;
If 's' is moved to the switch statement, the invalid value 's' would
be assigned to the input_mode.
Another potential problem is that we are mixing 'enum input_mode' and
ASCII characters. They could overwrap if we add more input modes.
To separate them out, set the flag field of long options to a pointer
of input_mode_opt. For mode select options, getopt_long() returns 0,
which never causes overwrap with ASCII characters that represent short
options.

Unify the similar build rules.
This supports 'make build_config', which builds scripts/kconfig/conf
but does not invoke it.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
scripts/kconfig/conf.c line 39 defines the default of input_mode as
oldaskconfig. Hence, 'make config' works in the same way even without
the --oldaskconfig option given. Note this in the help message.
This will be helpful to unify build rules in Makefile in the next
commit.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
scripts/kconfig/conf supports -? option to show the help message.
This is not wired up to Makefile, so nobody would notice this, but
it also shows 'invalid option' message.
$ ./scripts/kconfig/conf -?
./scripts/kconfig/conf: invalid option -- '?'
Usage: ./scripts/kconfig/conf [-s] [option] <kconfig-file>
[option] is _one_ of the following:
--listnewconfig List new options
--helpnewconfig List new options and help text
--oldaskconfig Start a new configuration using a line-oriented program
...
The reason is the '?' is missing in the short option list passed to
getopt_long().
While I fixed this issue, I also changed the option '?' to 'h'.
I prefer -h (or --help, if a long option is also desired).

conf_askvalue() is only called for oldconfig, syncconfig, and
oldaskconfig. If it is called for other cases, it is a bug.
So, the code after the switch statement is unreachable.

Unify the outer two if-conditionals into one. This decreases the

Changes the final fallback path in the ncurses locator for mconf
to support host compilers with a non-default sysroot.
This is similar to the hardcoded search for ncurses under
'/usr/include', but can support compilers that keep their default
header and library directories elsewhere.
For nconfig, do nothing because the only vendor compiler I'm aware
of with this layout (Apple Clang) ships an ncurses version that's too
old for nconfig anyway.

It is possible to keep this compatible with both Qt4 and Qt5, but it is

Previously, when you double-clicked the "int", "hex", or "string" menus,
a line-edit gadget showed up to allow you to input the value, which
looked clumsy.
Also, it was buggy; the editor opened even if the config option was not
editable. For example, just try to double-click CC_VERSION_TEXT, which
has no prompt.
This commit sub-classes QStyleItemDelegate to allow users to edit
"int", "hex", "string" menus in-place. Just double-click (or press
the F2 key) in the data column. Then, an editor widget is placed on
top of the item view.
The two methods are overridden:
createEditor - process only when the data column is being accessed
and the menu is visible. Otherwise, return nullptr to disallow editing.
setModelData - take the new data from the editor, and set it to the
addressed symbol. If it was successful, update all the list windows.
Otherwise, (the reason for the failure is possibly the input data was
out of range), set the old value back to the editor.

If you right-click in the ConfigList window, you will see the following
messages in the console:
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:888
QObject::connect: (sender name: 'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:897
QObject::connect: (sender name: 'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:906
QObject::connect: (sender name: 'config')
Right, there is no such slot in QAction. I think this is a typo of
setChecked.
Due to this bug, when you toggled the menu "Option->Show Name/Range/Data"
the state of the context menu was not previously updated. Fix this.

If you right-click the first row in the option tree, the pop-up menu
shows up, but if you right-click the second row or below, the event
is ignored due to the following check:
if (e->y() <= header()->geometry().bottom()) {
Perhaps, the intention was to show the pop-menu only when the tree
header was right-clicked, but this handler is not called in that case.
Since the origin of e->y() starts from the bottom of the header,
this check is odd.
Going forward, you can right-click anywhere in the tree to get the
pop-up menu.

This reverts commit cc1c08edcc.
Maxim Levitsky reports 'make xconfig' crashes since that commit
(https://lkml.org/lkml/2020/7/18/411)
Or, the following is simple test code that makes it crash:
menu "Menu"
config FOO
bool "foo"
default y
menuconfig BAR
bool "bar"
depends on FOO
endmenu
Select the Split View mode, and double-click "bar" in the right
window, then you will see Segmentation fault.
When 'last' is not set for symbolMode, the following code in
ConfigList::updateList() calls firstChild().
item = last ? last->nextSibling() : firstChild();
However, the pointer returned by ConfigList::firstChild() does not
seem to be compatible with (ConfigItem *), which seems another bug.
I'd rather want to reconsider whether hiding the goback icon is the
right thing to do.
In the following test code, the Split View shows "Menu2" and "Menu3"
in the right window. You can descend into "Menu3", but there is no way
to ascend back to "Menu2" from "Menu3".
menu "Menu1"
config FOO
bool "foo"
default y
menu "Menu2"
depends on FOO
menu "Menu3"
config BAZ
bool "baz"
endmenu
endmenu
endmenu
It is true that the goback button is currently not functional due to
yet another bug, but hiding the problem is not the right way to go.
Anyway, Segmentation fault is fatal. Revert the offending commit for
now, and we should find the right solution.

This reverts commit 5752ff07fd.
It added dead code to ConfigList:ConfigList().
The constructor of ConfigList has the initializer, mode(singleMode).
if (mode == symbolMode)
setHeaderLabels(QStringList() << "Item" << "Name" << "N" << "M" << "Y" << "Value");
else
setHeaderLabels(QStringList() << "Option" << "Name" << "N" << "M" << "Y" << "Value");
... always takes the else part.
The change to ConfigList::updateSelection() is strange too.
When you click the split view icon for the first time, the titles in
both windows show "Option". After you click something in the right
window, the title suddenly changes to "Item".
ConfigList::updateSelection() is not the right place to do this,
at least. It was not a good idea, I think.

gets wrong, the app could crash. So, instead, pass the name of
the symbol, and validate such symbol at the hyperlink handling
logic.

When the search dialog box finds symbols/menus that match
the search criteria, it presents all results at the window.
Clicking on a search result should make qconf to navigate
to the selected item. This works on singleMode and on
fullMode, but on splitMode, the navigation is broken.
This was partially caused by an incomplete Qt5 conversion
and by the followup patches that restored the original
behavior.
When qconf is on split mode, it has to update both the
config and the menu views. Right now, such logic is broken,
as it is not seeking using the right structures.
On qconf, the screen is split into 3 parts:
+------------+-------+
| | |
| Config | Menu |
| | |
+------------+-------+
| |
| ConfigInfo |
| |
+--------------------+
On singleMode and on fullMode, the menuView is hidden, and search
updates only the configList (which controls the ConfigView).
On SplitMode, the search logic should detect if the variable is a
leaf or not. If it is a leaf, it should be presented at the menuView,
and both configList and menuList should be updated. Otherwise, just
the configList should be updated.

The code block surrounded by 'if' ... 'endif' is reduced into if_stmt,
which is accepted in the 'choice' context. Therefore, you can write any
statements within a choice block by wrapping 'if y' ... 'end'.
For example, you can create a menu inside a choice, like follows:
---------------->8----------------
choice
prompt "choice"
config A
bool "A"
config B
bool "B"
if y
menu "strange menu"
config C
bool "C"
endmenu
endif
endchoice
---------------->8----------------
I want to change such a weird structure into a syntax error.
In fact, the USB gadget Kconfig had used nested 'choice' for no good
reason until commit df8df5e4bc ("usb: get rid of 'choice' for
legacy gadget drivers") killed it.
I think the 'source' inside 'choice' is on the fence. It is at least
gramatically sensible as long as the included file contains only
bool/tristate configs. However, it makes the code unreadable, and people
tend to forget the fact that the file is included from the choice
block. Commit 10e5e6c249 ("usb: gadget: move choice ... endchoice to
legacy/Kconfig") got rid of the only usecase.
Going forward, you can only use 'config', 'comment', and 'if' inside
'choice'. This also recursively applies to 'if' blocks inside 'choice'.
