* kconfig: Avoid buffer underrun in choice inputBen Hutchings2011-04-24
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linus wrote: This seems to make "make oldconfig" a _lot_ more verbose than it used to be. In a very annoying way. I just did a quick git bisect. It's introduced by commit 4062f1a4c030 ("kconfig: use long options in conf") by Sam Ravnborg. Apparently that thing is totally buggy, and doesn't just change the option names, but actively breaks them. The old behaviour (from years ago) were reintroduced by accident. Fix this so we are back to the version that are silent if there is nothing to ask about.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | savedefconfig will save a minimal config to a file named "defconfig". The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.

* kconfig: improve seed in randconfigIngo Molnar2009-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | 'make randconfig' uses glibc's rand function, and the seed of that PRNG is set via: srand(time(NULL)); But 'time()' only increases once every second - freezing the randconfig result within a single second. My Nehalem testbox does randconfig much faster than 1 second and i have a few scripts that do 'randconfig until condition X' loops. Those scripts currently waste a lot of CPU time due to randconfig changing its seed only once per second currently. Change the seed to be micrseconds based. (I checked the statistical spread of the seed - the now.tv_sec*now.tv_usec multiplication there further improves it.)

Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no compatibility checking amongst arguments; the last option will simply override earlier options. For example, 'conf -n -y foo' is perfectly valid now (input_mode will be set_yes). Previously, that would have been an error ("can't find file -y").

For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: - 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set config symbol from environment variable") - 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to set 64BIT with all*config targets") Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.

This patch series changes things so taht after the mouse click on the floppy disk icon, the icon is greyed out. If you mouse click on it now, nothing happens. If you change some CONFIG_*, the floppy disk icon returns to "active state", that is, if you mouse click it now, .config is written. This patch: Returns sym_change_count to reflect the .config's change state. All read only accesses of sym_change_count are replaced by calls to conf_get_changed() . mconfig.c is manipulated to ask for saving only when conf_get_changed() returned true.

* kconfig: fix .config dependenciesRoman Zippel2006-06-09
| | | | | | | | | | | | | | | | | | | | | | This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

* [PATCH] kconfig: preset config during all*configRoman Zippel2005-11-09
| | | | | | | | | | | | | | Allow to force setting of config variables during all{no,mod,yes,random}config to a specific value. For that conf first checks the KCONFIG_ALLCONFIG environment variable for a file name, otherwise it checks for all{no,mod,yes,random}.config and all.config. The file is a normal config file, which presets the config variables, but they are still subject to normal dependency checks.

* [PATCH] Kconfig i18n supportArnaldo Carvalho de Melo2005-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds i18n support for make *config, allowing users to have the config process in their own language. No printk was harmed in the process, don't worry, so all the bug reports, kernel messages, etc, remain in english, just the user tools to configure the kernel are internationalized. Users not interested in translations can just unset the related LANG, LC_ALL, etc env variables and have the config process in plain english, something like: LANG= make menuconfig is enough for having the whole config process in english. Or just don't install any translation file. Translations for brazilian portuguese are being done by a team of volunteers at: http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes To start the translation process: make update-po-config This will generate the pot template named scripts/kconfig/linux.pot, copy it to, say, ~/es.po, to start the translation for spanish. To test your translation, as root issue this command: msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po Replace "es" with your language code. Then execute, for instance: make menuconfig The current patch doesn't use any optimization to reduce the size of the generated .mo file, it is possible to use the config option as a key, but this doesn't prevent the current patch from being used or the translations done under the current scheme to be in any way lost if we chose to do any kind of keying. Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese) translation effort, Thiago Maciera for helping me with the gconf.cc (QT frontent) i18n coding and to all the volunteers that are already working on the first translation, to pt_BR. I left the question on whether to ship the translations with the stock kernel sources to be discussed here, please share your suggestions.
