2011-04-24kconfig: Avoid buffer underrun in choice inputBen Hutchings
Commit 40aee729b350 ('kconfig: fix default value for choice input') fixed some cases where kconfig would select the wrong option from a choice with a single valid option and thus enter an infinite loop. However, this broke the test for user input of the form 'N?', because when kconfig selects the single valid option the input is zero-length and the test will read the byte before the input buffer. If this happens to contain '?' (as it will in a mips build on Debian unstable today) then kconfig again enters an infinite loop.

Equivalent to af6c1598 (kconfig: handle comment entries within choice/endchoice), but for nconfig instead. Implement support for comment entries within choice groups. Comment entries are displayed visually distinct from normal configs, and selecting them is a no-op. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Michal Marek <mmarek@suse.cz>
2010-12-29kconfig: fix undesirable side effect of adding "visible" menu attributeJan Beulich
This lead to non-selected, non-user-selectable options to be written out to .config. This is not only pointless, but also preventing the user to be prompted should any of those options eventually become visible (e.g. by de-selecting the *_AUTO options the "visible" attribute was added for. Furthermore it is quite logical for the "visible" attribute of a menu to control the visibility of all contained prompts, which is what the patch does.

2010-12-21kconfig: simplify select-with-unmet-direct-dependency warningArnaud Lacombe
This is an attempt to simplify the expressing printed by kconfig when a symbol is selected but still has direct unmet dependency. First, the symbol reverse dependency is split in sub-expression. Then, each sub-expression is checked to ensure that it does not contains the unmet dependency. This removes the false-positive symbols and fixed symbol which already have the correct dependency. Finally, only the symbol responsible of the "select" is printed, instead of its full dependency tree.

2010-10-29kconfig: Have streamline_config process menuconfigs tooSteven Rostedt
Some menuconfigs in the Kconfig files have prompts and dependencies. Currently, streamline_config misses these, and this can cause streamline_config to keep modules enabled that should not be, and even worse, not enable those that should. This patch makes streamline_config process menuconfigs just like it would process a config. Reported-by: member graysky <graysky@archlinux.us> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2010-10-29kconfig: Fix streamline_config to read multi line deps in Kconfig filesSteven Rostedt
I noticed that some Kconfig files have multi line dependencies that continue with a backslash. Those dependencies on the next line will be missed by streamline_config. For example: config CS89x0 tristate "CS89x0 support" depends on NET_ETHERNET && (ISA || EISA || MACH_IXDP2351 \ || ARCH_IXDP2X01 || MACH_MX31ADS) The "|| ARCH_IXDP2X01 || MACH_MX31ADS)" will not be processed.

2010-09-20kconfig: fix menuconfig on debian lennyJunio C Hamano
In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15), support to link menuconfig with ncursesw library was added. To compute the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow ncursesw to be used as a replacement ncurses. However, when checking what header file to include, we do not check /usr/include/ncursesw directory. Add /usr/include/ncursesw to the list of directories that are checked. With this patch, on my Debian Lenny box with libncursesw5-dev package but not libncurses5-dev package, I can say "make menuconfig".
