2013-05-30kconfig/menu.c: fix multiple references to expressions in menu_add_prop()Dirk Gouders1-1/+14
menu_add_prop() applies upper menus' visibilities to actual prompts by AND-ing the prompts visibilities with the upper menus ones. This creates a further reference to the menu's visibilities and when the expression reduction functions do their work, they may remove or modify expressions that have multiple references, thus causing unpredictable side-effects. The following example Kconfig constructs a case where this causes problems: a menu and a prompt which's visibilities depend on the same symbol. When invoking mconf with this Kconfig and pressing "Z" we see a problem caused by a free'd expression still referenced by the menu's visibility: ------------------------------------------------------------------------ mainmenu "Kconfig Testing Configuration" config VISIBLE def_bool n config Placeholder bool "Place holder" menu "Invisible" visible if VISIBLE config TEST_VAR bool "Test option" if VISIBLE endmenu ------------------------------------------------------------------------ This patch fixes this problem by creating copies of the menu's visibility expressions before AND-ing them with the prompt's one.

2013-05-07menuconfig: fix NULL pointer dereference when searching a symbolLi Zefan1-6/+10
Searching for PPC_EFIKA results in a segmentation fault, and it's because get_symbol_prop() returns NULL. In this case CONFIG_PPC_EFIKA is defined in arch/powerpc/platforms/ 52xx/Kconfig, so it won't be parsed if ARCH!=PPC, but menuconfig knows this symbol when it parses sound/soc/fsl/Kconfig: config SND_MPC52xx_SOC_EFIKA tristate "SoC AC97 Audio support for bbplan Efika and STAC9766" depends on PPC_EFIKA This bug was introduced by commit bcdedcc1afd6 ("menuconfig: print more info for symbol without prompts").

2013-04-29localmodconfig: Process source kconfig files as they are foundSteven Rostedt1-10/+7
A bug was reported that caused localmodconfig to not keep all the dependencies of ATH9K. This was caused by the kconfig file: In drivers/net/wireless/ath/Kconfig: --- if ATH_CARDS config ATH_DEBUG bool "Atheros wireless debugging" ---help--- Say Y, if you want to debug atheros wireless drivers. Right now only ath9k makes use of this. source "drivers/net/wireless/ath/ath5k/Kconfig" source "drivers/net/wireless/ath/ath9k/Kconfig" source "drivers/net/wireless/ath/carl9170/Kconfig" source "drivers/net/wireless/ath/ath6kl/Kconfig" source "drivers/net/wireless/ath/ar5523/Kconfig" source "drivers/net/wireless/ath/wil6210/Kconfig" endif --- The current way kconfig works, it processes new source files after the first file is completed. It creates an array of new source config files and when the one file is finished, it continues with the next file. Unfortunately, this means that it loses the fact that the source file is within an "if" statement, and this means that each of these source file's configs will not have the proper dependencies set. As ATH9K requires ATH_CARDS set, the localmodconfig did not see that dependency, and did not enable ATH_CARDS. When the oldconfig was run, it forced ATH9K to be disabled.

2013-04-25kconfig: allow specifying the seed for randconfigYann E. MORIN1-1/+11
For reproducibility, it can be useful to be able to specify the seed to use to seed the RNG. Add a new KCONFIG_SEED environment variable which can be set to the seed to use: $ make KCONFIG_SEED=42 randconfig $ sha1sum .config 70a128c8dcc61303069e1be352cce64114dfcbca .config $ make KCONFIG_SEED=42 randconfig $ sha1sum .config 70a128c8dcc61303069e1be352cce64114dfcbca .config It's very usefull for eg. debugging the kconfig parser.

2013-04-25kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIGYann E. MORIN1-3/+4
Currently, randconfig does randomise choice entries, unless KCONFIG_ALLCONFIG is specified. For example, given those two files (Thomas' test-case): ---8<--- Config.test.in config OPTIONA bool "Option A" choice prompt "This is a choice" config CHOICE_OPTIONA bool "Choice Option A" config CHOICE_OPTIONB bool "Choice Option B" endchoice config OPTIONB bool "Option B" ---8<--- Config.test.in ---8<--- config.defaults CONFIG_OPTIONA=y ---8<--- config.defaults And running: ./scripts/kconfig/conf --randconfig Config.test.in does properly randomise the two choice symbols (and the two booleans). However, running: KCONFIG_ALLCONFIG=config.defaults \ ./scripts/kconfig/conf --randconfig Config.test.in does *not* reandomise the two choice entries, and only CHOICE_OPTIONA will ever be selected. (OPTIONA will always be set (expected), and OPTIONB will be be properly randomised (expected).) This patch defers setting that a choice has a value until a symbol for that choice is indeed set, so that choices are properly randomised when KCONFIG_ALLCONFIG is set, but not if a symbol for that choice is set. Also, as a side-efect, this patch fixes the following case: ---8<--- choice config OPTION_A bool "Option A" config OPTION_B bool "Option B" config OPTION_C bool "Option C" endchoice ---8<--- which could previously generate such .config files: ---8<--- ---8<--- CONFIG_OPTION_A=y CONFIG_OPTION_A=y CONFIG_OPTION_B=y # CONFIG_OPTION_B is not set # CONFIG_OPTION_C is not set CONFIG_OPTION_C=y ---8<--- ---8<--- Ie., the first entry in a choice is always set, plus zero or one of the other options may be set. This patch ensures that only one option may be set for a choice. Reported-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: "Yann E.

2013-04-25kconfig: do not override symbols already setYann E. MORIN1-1/+1
For randconfig, if a list of required symbols is specified with KCONFIG_ALLCONFIG, such symbols do not "have a value" as per sym_has_value(), but have the "valid" flag set. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
2013-04-25kconfig: fix randconfig tristate detectionYann E. MORIN1-1/+1
Because the modules' symbole (CONFIG_MODULES) may not yet be set when we check a symbol's tristate capabilty, we'll always find that tristate symbols are booleans, even if we randomly decided that to enable modules: sym_get_type(sym) always return boolean for tristates when modules_sym has not been previously set to 'y' *and* its value calculated *and* its visibility calculated, both of which only occur after we randomly assign values to symbols. Fix that by looking at the raw type of symbols. Tristate set to 'm' will be promoted to 'y' when their values will be later calculated. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
2013-04-16kconfig/lxdialog: rationalise the include paths where to find {.n}curses{,w}.hYann E. MORIN1-2/+2
The current code does this: if [ -f /usr/include/ncursesw/curses.h ]; then echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"' elif [ -f /usr/include/ncurses/ncurses.h ]; then echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"' elif [ -f /usr/include/ncurses/curses.h ]; then echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"' [...] This is merely inconsistent: - adding the full path to the directory in the -I directive, - especially since that path is already a sub-path of the system include path, - and then repeating the sub-path in the #include directive. Rationalise each include directive: - only use the filename in the #include directive, - keep the -I directives: they are always searched for before the system include path; this ensures the correct header is used. Using the -I directives and the filename-only in #include is more in line with how pkg-config behaves, eg.: $ pkg-config --cflags ncursesw -I/usr/include/ncursesw This paves the way for using pkg-config for CFLAGS, too, now we use it to find the libraries.

Viresh noticed when using merge_config.sh that a source softlink was being created even when he didn't specify the -O option. The problem arises due to the previous commit 409f117e2d6b which added the -O option. Basically if -O is not specified, we still pass '-O=.' to the make command, which then generates a source softlink to ./ This patch adds an extra check so if there is no -O specified to merge_config.sh, we don't pass one on to make.

Add a function that returns the CONFIG_ prefix to use (but keep the current hard-coded behavior, to be changed in a later patch). To avoid touching all the code that uses the CONFIG_ macro, we just undef it, and define it to be a call to the function. Signed-off-by: "Yann E.

2012-11-20kconfig: remove CONFIG_ from string constantsYann E. MORIN2-4/+17
Having the CONFIG_ prefix in string constants gets in the way of using a run-time-defined CONFIG_ prefix. Fix that by using temp growable strings (gstr) in which we printf the text. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>
2012-11-20menuconfig: fix extended colors ncurses supportKrzysztof Mazur1-0/+1
The ncurses library allows for extended colors. The support for extended colors support depends on wide-character support. ncurses headers enable extended colors (NCURSES_EXT_COLORS) only when wide-character support is enabled (NCURSES_WIDECHAR). The "make menuconfig" uses wide-character ncursesw library, which can be compiled with wide-character support, but does not define NCURSES_WIDECHAR and it's using headers without wide-character (and extended colors) support. This fixes problems with colors on systems with enabled extended colors (like PLD Linux). Without this patch "make menuconfig" is hard to use.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare2-2/+2
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

2012-10-01localmodconfig: Fix localyesconfig to set to 'y' not 'm'Yuta Ando1-0/+2
The kbuild target 'localyesconfig' has been same as 'localmodconfig' since the commit 50bce3e "kconfig/streamline_config.pl: merge local{mod,yes}config". The commit expects this script generates different configure depending on target, but it was not yet implemented. So I added code that sets to 'yes' when target is 'localyesconfig'.

an alias As 67d34a6a391369269a2e5dba8a5f42cc4cd50231 said, 'oldnoconfig' doesn't set new symbols to 'n', but instead sets it to their default values. So, this patch replaces 'oldnoconfig' with 'olddefconfig', stop making people confused, and keep the old name 'oldnoconfig' as an alias, because people already are dependent on its behavior with the counter-intuitive name.

2012-09-27menuconfig: Do not open code textbox scroll up/downBenjamin Poirier1-44/+11
We don't need to explicitely use ncurses' scroll(). ncurses performs vertical-motion optimization at wrefresh() time. Using strace I confirmed that with the following patch curses still sends only the new line of text to the terminal when scrolling up/down one line at a time.
