2016-05-26Merge branch 'kconfig' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild Pull kconfig update from Michal Marek: - fix for behavior of tristate choice items and fix for documentation of existing kconfig behavior [Dirk Gouders] - more helpful "unexpected data" kconfig warning [Paul Bolle] * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kconfig/symbol.c: handle choice_values that depend on 'm' symbols kconfig-language: elaborate on the type of a choice kconfig-language: fix comment on dependency-generated menu structures. kconfig: add unexpected data itself to warning
2016-05-10kconfig/symbol.c: handle choice_values that depend on 'm' symbolsDirk Gouders
If choices consist of choice_values of type tristate that depend on symbols set to 'm', those choice_values are not set to 'n' if the choice is changed from 'm' to 'y' (in which case only one active choice_value is allowed). Those values are also written to the config file causing modules to be built when they should not. The following config can be used to reproduce and examine the problem; with the frontend of your choice set "Choice 0" and "Choice 1" to 'm', then set "Tristate Choice" to 'y' and save the configuration: config modules boolean modules default y option modules config dependency tristate "Dependency" default m choice prompt "Tristate Choice" default choice0 config choice0 tristate "Choice 0" config choice1 tristate "Choice 1" depends on dependency endchoice This patch sets tristate choice_values' visibility that depend on symbols set to 'm' to 'n' if the corresponding choice is set to 'y'. This makes them disappear from the choice list and will also cause the choice_values' value set to 'n' in sym_calc_value() and as a result they are written as "not set" to the resulting .config file.

If the .config parser runs into unexpected data it emits warnings like: .config:6911:warning: unexpected data Add the unexpected data itself to this warning.

2016-04-26localmodconfig: Fix whitespace repeat count after "tristate"Benjamin Poirier
Also recognize standalone "prompt". Before this patch we incorrectly identified some symbols as not having a prompt and potentially needing to be selected by something else. Note that this patch could theoretically change the resulting .config, causing it to have fewer symbols turned on. However, given the current set of Kconfig files, this situation does not occur because the symbols newly added to %prompts are absent from %selects.

2016-04-26localmodconfig: Reset certificate pathsBenjamin Poirier
When using `make localmodconfig` and friends, if the input config comes from a kernel that was built in a different environment (for example, the canonical case of using localmodconfig to trim a distribution kernel config) the key files for module signature checking will not be available and should be regenerated or omitted. Otherwise, the user will be faced with annoying errors when trying to build with the generated .config: make[1]: *** No rule to make target 'keyring.crt', needed by 'certs/x509_certificate_list'. Stop.

2016-04-26localmodconfig: Add missing $ to reference a variableBenjamin Poirier
That is clearly what the original intention was. This does not change the output .config but it prevents some useless processing. ! eq "m" is changed to the simpler eq "y"; symbols with values other than m|y are not included in %orig_configs.

2016-04-26localmodconfig: Fix parsing of "help" textBenjamin Poirier
Help text may start with "help" or "---help---". This patch fixes read_kconfig() to recognize the second variant. This removes useless junk from %depends and %selects. That junk is due to help text that contains the words "selects" and "depends".

2016-04-26localmodconfig: Recognize more keywords that end a menu entryBenjamin Poirier
Based on the list in Documentation/kbuild/kconfig-language.txt This removes junk from %depends because parsing of a menu entry spilled over to another menu entry.

2016-04-26localmodconfig: Fix parsing of Kconfig "source" statementsBenjamin Poirier
The parameter of Kconfig "source" statements does not need to be quoted. The current regex causes many kconfig files to be skipped and hence, dependencies to be missed.

2016-02-01unbreak allmodconfig KCONFIG_ALLCONFIG=...Al Viro
Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections?

2016-01-11kconfig: fix qconf segfault by deleting heap objectsChris Bainbridge
On Debian stable (qt-4.8.6) 'make xconfig' intermittently fails due to qconf segfaulting at exit time in QXcbEventReader. The cause of this is destructors on the heap objects never being called, so fix this by properly deleting the heap objects before exit.

2016-01-05kconfig: return 'false' instead of 'no' in bool functionVegard Nossum
menu_is_visible() is a bool function and should use boolean return values. "no" is a tristate value which happens to also have a value of 0, but we should nevertheless use the right symbol for it. This is a very minor cleanup with no semantic change.

2015-11-02Use pkg-config to find Qt 4 and 5 instead of direct qmakeThiago Macieira
The Qt Project recommendation is that there should always be a "qmake" binary and it should never be renamed. If it's necessary to handle multiple Qt versions, the Qt Project recommends using qtchooser. Unfortunately, some distros do not follow the recommendation, so we would need to check qmake-qt4, qmake-qt5, etc. So, instead, let's try pkg-config.

2015-10-15scripts/kconfig/Makefile: Fix KBUILD_DEFCONFIG check when building with O=Michael Ellerman
My recent commit d2036f30cfe1 ("scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target"), contained a bug in that when it checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to the path. This causes the build to fail when building out of tree (with O=), and when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will fail to find the 'defconfig' file, because we look in the build directory not $(srctree), and so we will call Make again with 'defconfig' as the target. From there we loop infinitely calling 'make defconfig' again and again. The fix is simple, we need to look for the file under $(srctree).

2015-10-14kconfig/merge_config.sh: Support KCONFIG_CONFIGGabriel de Perthuis
All make targets support $KCONFIG_CONFIG because they run scripts/kconf. Make sure merge_config.sh accesses the correct file in all cases. Previously this script broke in two different code paths, one for targets like kvmconfig (which use merge_config.sh -m then call a target that respects KCONFIG_CONFIG) and one for direct use of the script without -m, which called make rules that edit KCONFIG_CONFIG but verified a different file.

2015-10-14Update the buildsystem for KConfig finding QtThiago Macieira
The buildsystem will now only search for Qt 4 and Qt 5. Support for Qt 2 and 3 was dropped in the previous commits (Qt 3 was EOL'ed in 2010 or so...). For Qt 5, to be future-proof with the future direction notice appearing in the 5.5 release, C++11 support is automatically enabled.
