2015-12-10kconfig: allow kconfig to handle longer path namesMarkus Mayer1-3/+4
The current (arbitrary) limit of 128 characters for path names has proven too short for Android builds, as longer path names are used there. Change conf.c, so it can handle path lengths up to PATH_MAX characters. Signed-off-by: Markus Mayer <mmayer@broadcom.com> Signed-off-by: Michal Marek <mmarek@suse.com>

2013-06-24kconfig: loop as long as we changed some symbols in randconfigYann E. MORIN1-1/+2
Because of choice-in-a-choice constructs, it can happen that not all symbols are assigned a value during randconfig, leading in rare cases to this situation: ---8<--- choice-in-choice.in choice bool "A/B/C" config A bool "A" config B bool "B" if B choice bool "E/F" config E bool "E" config F bool "F" endchoice endif # B config C bool "C" endchoice ---8<--- $ ./scripts/kconfig/conf --randconfig choice-in-choice.in [--SNIP--] $ ./scripts/kconfig/conf --silentoldconfig choice-in-choice.in </dev/null [--SNIP--] A/B/C 1. A (A) > 2. B (B) 3. C (C) choice[1-3]: 2 E/F > 1. E (E) (NEW) 2. F (F) (NEW) choice[1-2]: aborted! Console input/output is redirected. Run 'make oldconfig' to update configuration. Fix this by looping in randconfig for as long as some symbol gets assigned a value. Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP), which uses this choice-in-a-choice construct, and exhibits this problem. The example above is just a stripped-down minimalist test-case. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

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.

2012-05-07kbuild: all{no,yes,mod,def,rand}config only read files when instructed to.Eric W. Biederman1-1/+3
Prevent subtle surprises to both people working on the kconfig code and people using make allnoconfig allyesconfig allmoconfig and randconfig by only attempting to read a config file if KCONFIG_ALLCONFIG is set. Common sense suggests attempting to read the extra config files does not make sense unless requested. The documentation says the code won't attempt to read the extra config files unless requested. Current usage does not appear to include people depending on the code reading the config files without the variable being set So do the simple thing and stop reading config files when passed all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment variable is set.

2011-04-24kconfig: Avoid buffer underrun in choice inputBen Hutchings1-1/+1
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.

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.

2010-08-03kconfig: add savedefconfigSam Ravnborg1-0/+14
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.

'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.)

Switch from doing our own parsing of command line arguments to using getopt(3) to do 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").
