kconfig/menu.c: fix multiple references to expressions in menu_add_prop()

2013-05-29T22:14:01Z

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.

menuconfig: fix NULL pointer dereference when searching a symbol

2013-05-07T14:55:36Z

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").

menuconfig: print more info for symbol without prompts

2013-05-01T00:04:09Z

When we search a config symbol, if it has no prompt the position of this symbol in the Kconfig file and it's dependencies are not printed. This can be inconvenient, especially when it's set to n and we want to find out why. the following is an example: before: Symbol: GENERIC_SMP_IDLE_THREAD [=y] Type : boolean Selected by: X86 [=y] after: Symbol: GENERIC_SMP_IDLE_THREAD [=y] Type : boolean Defined at arch/Kconfig:213 Selected by: X86 [=y] Signed-off-by: Weng Meiling Signed-off-by: Libo Chen Cc: Michal Marek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Merge branch 'kbuild/rc-fixes' into kbuild/kconfig

There is one kconfig fix in the rc-fixes branch that I forgot to submit for 3.8, so let's add it to the kconfig branch for 3.9-rc1.

menuconfig: Assign jump keys per-page instead of globally

2012-09-27T16:09:24Z

At the moment, keys 1-9 are assigned to the first 9 search results. This patch makes them assigned to the first 9 results per-page instead. We are much less likely to run out of keys that way. Signed-off-by: Benjamin Poirier Signed-off-by: Michal Marek

menuconfig: Add jump keys to search results

2012-09-27T16:09:24Z

makes it possible to jump directly to the menu for a configuration entry after having searched for it with '/'. If this menu is not currently accessible we jump to the nearest accessible parent instead. After exiting this menu, the user is returned to the search results where he may jump further in or elsewhere. Signed-off-by: Benjamin Poirier Signed-off-by: Michal Marek

kbuild: Fix help text not displayed in choice option.

2011-08-08T14:01:54Z

Help text under choice menu is never displayed because it does not have symbol name associated with it, however many kconfigs have help text under choice, assuming that it will be displayed when user selects help. for example in Kconfig if we have: choice prompt "Choice" ---help--- HELP TEXT ... config A bool "A" config B bool "B" endchoice Without this patch "HELP TEXT" is not displayed when user selects help option when "Choice" is highlighted from menuconfig or xconfig or gconfig. This patch changes the logic in menu_get_ext_help to display help for cases which dont have symbol names like choice.
