2018-04-13kconfig: extend output of 'listnewconfig'Don Zickus
We at Red Hat/Fedora have generally tried to have a per file breakdown of every config option we set. This makes it easy for us to add new options when they are exposed and keep a changelog of why they were set. A Fedora example is here: https://src.fedoraproject.org/cgit/rpms/kernel.git/tree/configs/fedora/generic Using various merge scripts, we build up a config file and run it through 'make listnewconfig' and 'make oldnoconfig'. The idea is to print out new config options that haven't been manually set and use the default until a patch is posted to set it properly. To speed things up, it would be nice to make it easier to generate a patch to post the default setting. The output of 'make listnewconfig' has two issues that limit us: - it doesn't provide the default value - it doesn't provide the new 'choice' options that get flagged in 'oldconfig' This patch extends 'listnewconfig' to address the above two issues. This allows us to run a script make listnewconfig | rhconfig-tool -o patches; git send-email patches/ The output of 'make listnewconfig': CONFIG_NET_EMATCH_IPT CONFIG_IPVLAN CONFIG_ICE CONFIG_NET_VENDOR_NI CONFIG_IEEE802154_MCR20A CONFIG_IR_IMON_DECODER CONFIG_IR_IMON_RAW The new output of 'make listnewconfig': CONFIG_KERNEL_XZ=n CONFIG_KERNEL_LZO=n CONFIG_NET_EMATCH_IPT=n CONFIG_IPVLAN=n CONFIG_ICE=n CONFIG_NET_VENDOR_NI=y CONFIG_IEEE802154_MCR20A=n CONFIG_IR_IMON_DECODER=n CONFIG_IR_IMON_RAW=n Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-03-26kconfig: rename silentoldconfig to syncconfigMasahiro Yamada
As commit cedd55d49dee ("kconfig: Remove silentoldconfig from help and docs; fix kconfig/conf's help") mentioned, 'silentoldconfig' is a historical misnomer. That commit removed it from help and docs since it is an internal interface. If so, it should be allowed to rename it to something more intuitive. 'syncconfig' is the one I came up with because it updates the .config if necessary, then synchronize include/generated/autoconf.h and include/config/* with it. You should not manually invoke 'silentoldcofig'. Display warning if used in case existing scripts are doing wrong.

2018-03-26kconfig: hide irrelevant sub-menus for oldconfigMasahiro Yamada
Historically, "make oldconfig" has changed its behavior several times, quieter or louder. (I attached the history below.) Currently, it is not as quiet as it should be. This commit addresses it. Test Case --------- ---------------------------(Kconfig)---------------------------- menu "menu" config FOO bool "foo" menu "sub menu" config BAR bool "bar" endmenu endmenu menu "sibling menu" config BAZ bool "baz" endmenu ---------------------------------------------------------------- ---------------------------(.config)---------------------------- CONFIG_BAR=y CONFIG_BAZ=y ---------------------------------------------------------------- With the Kconfig and .config above, "make silentoldconfig" and "make oldconfig" work differently, like follows: $ make silentoldconfig scripts/kconfig/conf --silentoldconfig Kconfig * * Restart config... * * * menu * foo (FOO) [N/y/?] (NEW) y # # configuration written to .config # $ make oldconfig scripts/kconfig/conf --oldconfig Kconfig * * Restart config... * * * menu * foo (FOO) [N/y/?] (NEW) y * * sub menu * bar (BAR) [Y/n/?] y # # configuration written to .config # Both hide "sibling node" since it is irrelevant. The difference is that silentoldconfig hides "sub menu" whereas oldconfig does not. The behavior of silentoldconfig is preferred since the "sub menu" does not contain any new symbol. The root cause is in conf(). There are three input modes that can call conf(); oldaskconfig, oldconfig, and silentoldconfig. Everytime conf() encounters a menu entry, it calls check_conf() to check if it contains new symbols. If no new symbol is found, the menu is just skipped. Currently, this happens only when input_mode == silentoldconfig. The oldaskconfig enters into the check_conf() loop as silentoldconfig, so oldaskconfig works likewise for the second loop or later, but it never happens for oldconfig. So, irrelevant sub-menus are shown for oldconfig. Change the test condition to "input_mode != oldaskconfig". This is false only for the first loop of oldaskconfig; it must ask the user all symbols, so no need to call check_conf(). History of oldconfig -------------------- [0] Originally, "make oldconfig" was as loud as "make config" (It showed the entire .config file) [1] Commit cd9140e1e73a ("kconfig: make oldconfig is now less chatty") made oldconfig quieter, but it was still less quieter than silentoldconfig. (oldconfig did not hide sub-menus) [2] Commit 204c96f60904 ("kconfig: fix silentoldconfig") changed the input_mode of oldconfig to "ask_silent" from "ask_new". So, oldconfig really became as quiet as silentoldconfig. (oldconfig hided irrelevant sub-menus) [3] Commit 4062f1a4c030 ("kconfig: use long options in conf") made oldconfig as loud as [0] due to misconversion. [4] Commit 14828349719a ("kconfig: fix make oldconfig") addressed the misconversion of [3], but it made oldconfig quieter only to the same level as [1], not [2]. This commit is restoring the behavior of [2]. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Ulf Magnusson <ulfalizer@gmail.com>

2018-03-26kconfig: do not call check_conf() for olddefconfigMasahiro Yamada
check_conf() traverses the menu tree, but it is completely no-op for olddefconfig because the following if-else block does nothing. if (input_mode == listnewconfig) { ... } else if (input_mode != olddefconfig) { ... } As the help message says, olddefconfig automatically sets new symbols to their default value. There is no room for manual intervention. So, calling check_conf() for olddefconfig is odd in the first place.

2018-02-09kconfig: echo stdin to stdout if either is redirectedMasahiro Yamada
If stdio is not tty, conf_askvalue() puts additional new line to prevent prompts from being concatenated into a single line. This care is missing in conf_choice(), so a 'choice' prompt and the next prompt are shown in the same line. Move the code into xfgets() to cater to all cases. To improve this more, let's echo stdin to stdout. This clarifies what keys were input from stdio and the stdout looks like as if it were from tty.

2013-06-24kconfig: loop as long as we changed some symbols in randconfigYann E. MORIN
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.

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.

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.

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.

They're useful in distro kernel packages where the config files are built using a combination of smaller config files. Arjan van de Ven wrote the initial nonint_config and Roland McGrath added the loose_nonint_oldconfig.
