| * scripts/dtc: Fix a resource leakMartin Ettl2010-07-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | during a check of the current git head of the linux kernel with the static code analysis tool cppcheck (http://sourceforge.net/apps/mediawiki/cppcheck/index.php?title=Main_Page) the tool discovered a resource leak in linux-2.6/scripts/dtc/fstree.c. Please refer the attached patch, that fixes the issue.

| * Add support for the C variable in the coccicheck scriptNicolas Palix2010-06-281-25/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes it possible to use the Coccinelle checker with the C variable of the build system. To check only newly edited code, the following command may be used: 'make C={1,2} CHECK="scripts/coccicheck"' This runs every semantic patch in scripts/coccinelle by default. The COCCI variable may additionally be used to only apply a single semantic patch.

It can be called with four different modes. Each one generates a different kind of output, i.e. context, patch, org, report, according to the corresponding mode to be activated. The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.

| * | checkkconfigsymbols.sh: Kconfig symbols sometimes have lowercase lettersRoland Dreier2010-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quite a few Kconfig symbols contain lowercase letters. The current checkkconfigsymbols.sh code only contains A-Z in the regexp it uses to find config symbols in source code, so it comes up with the wrong symbol to look for in Kconfig files and then generates false positives when it doesn't find that wrong symbol. For example checking drivers/net generates a false positive for MAC89 because the the actual config option is MAC89x0. Fix this by also adding a-z to the regexp.

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.

The problem is that MODULES is never evaluted in conf_read_simple() unless there's a .config. The following patch fixes this.

Enable the block layer (BLOCK) [Y/?] (NEW) y ... You can also notice this bug when using gconfig/xconfig. It's because the SYMBOL_DEF_USER bit of an invisible symbol is cleared when the config file is read: int conf_read(const char *name) { ... for_all_symbols(i, sym) { if (sym_has_value(sym) && !sym_is_choice_value(sym)) { /* Reset values of generates values, so they'll appear * as new, if they should become visible, but that * doesn't quite work if the Kconfig and the saved * configuration disagree. */ if (sym->visible == no && !conf_unsaved) sym->flags &= ~SYMBOL_DEF_USER; ... } But a menu item which represents an invisible symbol is still visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER bit should be set to indicate it's not NEW.

| * | | kconfig: introduce nonint_oldconfig and loose_nonint_oldconfigAristeu Rozanski2010-06-022-9/+54
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has been around for a long time in Fedora and Red Hat Enterprise Linux kernels and it may be useful for others. The nonint_oldconfig target will fail and print the unset config options while loose_nonint_oldconfig will simply let the config option unset. 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.

For a quick example, navigate to the kernel compression options and get the help for bzip2. Doing so triggers a call to mvwprintw() with a string containing '%' and no extra arguments to fill in the specifier's value. Fix this case by printing the literal string retrieved from the kconfig. #0 0x00002b52b6b11d83 in vfprintf () from /lib/libc.so.6 #1 0x00002b52b6bad010 in __vsnprintf_chk () from /lib/libc.so.6 #2 0x00002b52b623991b in _nc_printf_string () from /lib/libncursesw.so.5 #3 0x00002b52b6234cff in vwprintw () from /lib/libncursesw.so.5 #4 0x00002b52b6234db9 in mvwprintw () from /lib/libncursesw.so.5 #5 0x00000000004151d8 in fill_window (win=0x21b64c0, text=0x21b62b0 "CONFIG_KERNEL_BZIP2:\n\nIts compression ratio and speed is intermediate.\nDecompression speed is slowest among the three.

(dot) builtin. While the former is supported only by bash, the latter is specified in POSIX and works fine with all POSIX-compliant shells I am aware of. The '$_' special parameter is specific to bash. It is partially supported in dash too but it always evaluates to the current script path (which causes the script to enter a loop recursively re-executing itself). This is why I have replaced the two occurences of '$_' with the explicit parameter. The 'local' builtin is another example of bash-specific code. Although it is supported by all POSIX-compliant shells I am aware of, it is not part of POSIX specification and thus the code should not rely on it assigning a specific value to the local variable. Moreover, the 'posh' shell has a limited version of 'local' builtin not supporting direct variable assignments. Thus, I have broken one of the 'local' declarations down into a (non-POSIX) 'local' declaration and a plain (POSIX-compliant) variable assignment.
