kconfig: fix infinite loop when expanding a macro at the end of file

2024-03-26T22:20:05+00:00

[ Upstream commit af8bbce92044dc58e4cc039ab94ee5d470a621f5 ] A macro placed at the end of a file with no newline causes an infinite loop. [Test Kconfig] $(info,hello) \ No newline at end of file I realized that flex-provided input() returns 0 instead of EOF when it reaches the end of a file.

kconfig: rename a variable in the lexer to a clearer name

2021-09-29T17:08:59+00:00

In Kconfig, like Python, you can enclose a string by double-quotes or single-quotes. So, both "foo" and 'foo' are allowed. The variable, "str", is used to remember whether the string started with a double-quote or a single-quote because open/closing quotation marks must match. The name "str" is too generic to understand the intent. Rename it to "open_quote", which is easier to understand. The type should be 'char'.

kconfig: narrow the scope of variables in the lexer

2021-09-29T17:05:10+00:00

The variables, "ts" and "i", are used locally in the action of the [ \t]+ pattern in the start state. Define them where they are used. Signed-off-by: Masahiro Yamada

kconfig: change "modules" from sub-option to first-level attribute

2021-04-14T06:22:49+00:00

Now "modules" is the only member of the "option" property. Remove "option", and move "modules" to the top level property. Signed-off-by: Masahiro Yamada

kconfig: remove allnoconfig_y option

2021-04-14T06:22:49+00:00

Now that the only user, CONFIG_EMBEDDED has stopped using this option, remove it entirely. Signed-off-by: Masahiro Yamada

kconfig: change defconfig_list option to environment variable

2021-04-14T06:22:48+00:00

"defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada

kconfig: add 'static' to some file-local data

2020-08-14T04:30:04+00:00

Fix some warnings from sparce like follows: warning: symbol '...' was not declared. Should it be static? Signed-off-by: Masahiro Yamada

kconfig: remove '---help---' support

2020-08-14T04:30:03+00:00

The conversion is done. No more user of '---help---'. Cc: Ulf Magnusson Signed-off-by: Masahiro Yamada

kconfig: use snprintf for formatting pathnames

2019-05-14T14:23:25+00:00

Valid pathnames will never exceed PATH_MAX, but these file names are unsanitized and can cause buffer overflow if set incorrectly. Use snprintf to avoid this. This was flagged during a Coverity scan of the coreboot project, which also uses kconfig for its build system. Signed-off-by: Jacob Garber Signed-off-by: Masahiro Yamada
