2020-10-09Merge branch 'kcsan' of ↵Ingo Molnar2-7/+16
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into locking/core Pull KCSAN updates for v5.10 from Paul E. McKenney: - Improve kernel messages. - Be more permissive with bitops races under KCSAN_ASSUME_PLAIN_WRITES_ATOMIC=y. - Optimize debugfs stat counters. - Introduce the instrument_*read_write() annotations, to provide a finer description of certain ops - using KCSAN's compound instrumentation. Use them for atomic RNW and bitops, where appropriate. Doing this might find new races. (Depends on the compiler having tsan-compound-read-before-write=1 support.) - Support atomic built-ins, which will help certain architectures, such as s390. - Misc enhancements and smaller fixes.

When building with $ HOST_EXTRACFLAGS=-g make the expectation is that host tools are built with debug informations. This however doesn't happen if the Makefile assigns a new value to the HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for the first assignment.

2020-09-05checkpatch: fix the usage of capture group ( ... )Mrinal Pandey1-2/+2
The usage of "capture group (...)" in the immediate condition after `&&` results in `$1` being uninitialized. This issues a warning "Use of uninitialized value $1 in regexp compilation at ./scripts/checkpatch.pl line 2638". I noticed this bug while running checkpatch on the set of commits from v5.7 to v5.8-rc1 of the kernel on the commits with a diff content in their commit message. This bug was introduced in the script by commit e518e9a59ec3 ("checkpatch: emit an error when there's a diff in a changelog"). It has been in the script since then. The author intended to store the match made by capture group in variable `$1`. This should have contained the name of the file as `[\w/]+` matched. However, this couldn't be accomplished due to usage of capture group and `$1` in the same regular expression. Fix this by placing the capture group in the condition before `&&`. Thus, `$1` can be initialized to the text that capture group matches thereby setting it to the desired and required value.

2020-08-25kcsan: Support compounded read-write instrumentationMarco Elver1-1/+1
Add support for compounded read-write instrumentation if supported by the compiler. Adds the necessary instrumentation functions, and a new type which is used to generate a more descriptive report. Furthermore, such compounded memory access instrumentation is excluded from the "assume aligned writes up to word size are atomic" rule, because we cannot assume that the compiler emits code that is atomic for compound ops. LLVM/Clang added support for the feature in: https://github.com/llvm/llvm-project/commit/785d41a261d136b64ab6c15c5d35f2adc5ad53e3 The new instrumentation is emitted for sets of memory accesses in the same basic block to the same address with at least one read appearing before a write. These typically result from compound operations such as ++, --, +=, -=, |=, &=, etc. but also equivalent forms such as "var = var + 1". Where the compiler determines that it is equivalent to emit a call to a single __tsan_read_write instead of separate __tsan_read and __tsan_write, we can then benefit from improved performance and better reporting for such access patterns. The new reports now show that the ops are both reads and writes, for example: read-write to 0xffffffff90548a38 of 8 bytes by task 143 on cpu 3: test_kernel_rmw_array+0x45/0xa0 access_thread+0x71/0xb0 kthread+0x21e/0x240 ret_from_fork+0x22/0x30 read-write to 0xffffffff90548a38 of 8 bytes by task 144 on cpu 2: test_kernel_rmw_array+0x45/0xa0 access_thread+0x71/0xb0 kthread+0x21e/0x240 ret_from_fork+0x22/0x30 Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Paul E.

2020-08-14kconfig: qconf: move setOptionMode() to ConfigList from ConfigViewMasahiro Yamada2-28/+27
ConfigView::setOptionMode() only gets access to the 'list' member. Move it to the more relevant ConfigList class. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: do not limit the pop-up menu to the first rowMasahiro Yamada1-34/+34
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.

2020-08-14kconfig: qconf: refactor icon setupsMasahiro Yamada2-14/+27
These icon data are used by ConfigItem, but stored in each instance of ConfigView. There is no point to keep the same data in each of 3 instances, "menu", "config", and "search". Move the icon data to the more relevant ConfigItem class, and make them static members. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove unused voidPix, menuInvPixMasahiro Yamada2-2/+2
These are initialized, but not used by anyone. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove ConfigItem::text/setTextMasahiro Yamada1-8/+0
Use QTreeWidgetItem::text/setText directly Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove ConfigList::addColumn/removeColumnMasahiro Yamada2-19/+11
Use QTreeView::showColumn/hideColumn directly. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove ConfigItem::pixmap/setPixmapMasahiro Yamada2-19/+11
Use QTreeWidgetItem::icon/setIcon directly. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: drop more localization codeMasahiro Yamada1-8/+3
This is a remnant of commit 694c49a7c01c ("kconfig: drop localization support"). Get it back to the code prior to commit 3b9fa0931dd8 ("[PATCH] Kconfig i18n support"). Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove 'parent' from ConfigList::updateMenuList()Masahiro Yamada2-10/+10
All the call-sites of this function pass 'this' to the first argument. So, 'parent' is always the 'this' pointer. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove unused argument from ConfigView::updateList()Masahiro Yamada2-5/+5
Now that ConfigList::updateList() takes no argument, the 'item' argument ConfigView::updateList() is no longer used. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove unused argument from ConfigList::updateList()Masahiro Yamada2-5/+5
This function allocates 'item' before using it, so the argument 'item' is always shadowed. Remove the meaningless argument. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: omit parent to QHBoxLayout()Masahiro Yamada1-1/+2
Instead of passing 0 (i.e. nullptr), leave it empty. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove name from ConfigSearchWindow constructorMasahiro Yamada2-24/+22
This constructor is only called with "search" as the second argument. Hard-code the name in the constructor, and drop it from the function argument. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove unused ConfigList::listView()Masahiro Yamada1-4/+0
I do not know how this function can be useful. In fact, it is unsed. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: overload addToolBar() to create and insert toolbarMasahiro Yamada1-3/+1
Use the overloaded function, addToolBar(const QString &title) to create a QToolBar object, setting its window title, and inserts it into the toolbar area. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove toolBar from ConfigMainWindow membersMasahiro Yamada2-2/+1
This pointer is only used in the ConfigMainWindow constructor. Drop it from the private members. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: use 'menu' variable for (QMenu *)Masahiro Yamada1-21/+20
The variable 'config' for the file menu is inconsistent. You do not need to use different variables. Use 'menu' for every menu. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: do not use 'menu' variable for (QMenuBar *)Masahiro Yamada1-6/+5
I think it is a bit confusing to use 'menu' to hold a QMenuBar pointer. I want to use 'menu' for a QMenu pointer. You do not need to use a local variable here. Use menuBar() directly. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: remove ->addSeparator() to menuBarMasahiro Yamada1-1/+0
I do not understand the purpose of this ->addSeparator(). It does not make any difference. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: add 'static' to some file-local dataMasahiro Yamada2-5/+11
Fix some warnings from sparce like follows: warning: symbol '...' was not declared. Should it be static? Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-08-14kconfig: qconf: Fix mouse events in search viewMaxime Chretien1-2/+3
On menu properties mouse events didn't do anything in search view (listMode). As there are no menus in listMode we can add an exception in tests to always change the value on mouse events if we are in listMode.
