| * checkkconfigsymbols.py: improve detection of defectsValentin Rothberg2014-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the detection of defects by updating the regular expression to find Kconfig identifiers in the source code, and fixes some cases of false positives. The following changes are made: - improve regex to find Kconfig identifiers in the source - exclude .log files from analysis - improve filtering of false positives (e.g, CONFIG_XXX) - change output format from (feature:\tlist) to (feature\tlist) Signed-off-by: Valentin Rothberg <valentinrothberg@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
| * checkkconfigsymbols.sh: reimplementation in pythonValentin Rothberg2014-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The scripts/checkkconfigsymbols.sh script searches Kconfig features in the source code that are not defined in Kconfig. Such identifiers always evaluate to false and are the source of various kinds of bugs. However, the shell script is slow and it does not detect such broken references in Kbuild and Kconfig files (e.g., ``depends on UNDEFINED´´). Furthermore, it generates false positives. The script is also hard to read and understand, and is thereby difficult to maintain. This patch replaces the shell script with an implementation in Python, which: (a) detects the same bugs, but does not report previous false positives (b) additionally detects broken references in Kconfig and all non-Kconfig files, such as Kbuild, .[cSh], .txt, .sh, defconfig, etc. (c) is up to 75 times faster than the shell script (d) only checks files under version control The new script reduces the runtime on my machine (i7-2620M, 8GB RAM, SSD) from 3m47s to 0m3s, and reports 938 broken references in Linux v3.17-rc1; 419 additional reports of which 16 are located in Kconfig files, 287 in defconfigs, 63 in ./Documentation, 1 in Kbuild. Moreover, we intentionally include references in comments, which have been ignored until now. Such comments may be leftovers of features that have been removed or renamed in Kconfig (e.g., ``#endif /* CONFIG_MPC52xx */´´). These references can be misleading and should be removed or replaced. Note that the output format changed from (file list <tab> feature) to (feature <tab> file list) as it simplifies the detection of the Kconfig feature for long file lists.

Either it is a nop (right now it's an unconditional branch, which skips the mcount block), or it's a branch to the ftrace_caller() function. If a kprobe is being placed on a function tracer calling instruction we encode if we actually have a nop or branch in the remaining bytes after the breakpoint instruction (illegal opcode). This is possible, since the size of the instruction used for the nop and branch is six bytes, while the size of the breakpoint is only two bytes. Therefore the first two bytes contain the illegal opcode and the last four bytes contain either "0" for nop or "1" for branch. The kprobes code will then execute/simulate the correct instruction. Instruction patching for kprobes and function tracer is always done with stop_machine(). Therefore we don't have any races where an instruction is patched concurrently on a different cpu. Besides that also the program check handler which executes the function trace caller instruction won't be executed concurrently to any stop_machine() execution. This allows to keep full fault based kprobes handling which generates correct pt_regs contents automatically.

* | checkpatch: allow certain SI units with three charactersJulius Werner2014-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checkpatch flags CamelCase identifiers in strict mode, but it has a feature to ignore parts with only two characters to allow for SI units like mV or uA. Unfortunately, not all SI units fit in two characters, and not all are lower case followed by upper case. This patch adds hardcoded detection for frequency and 1024-based size units (Hz/KHz/MHz/GHz/THz and KiB/MiB/GiB/TiB), since allowing any three character combinations might be too lenient. The list can later be expanded as needed.

Further, the whole entry did not work, because the regex needs to match from the beginning of a line, including keywords like 'static'. Finally, '\w' should not be used, because it stops at underscores which are often part of variable names in C, resulting in wrong entries in the tags file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | $(if $(KBUILD_SRC),$(srctree)/) was a useful strategy to omit a long absolute path for in-source-tree build prior to commit 890676c65d699db3ad82e7dddd0cf8fb449031af (kbuild: Use relative path when building in the source tree). Now $(srctree) is "." when building in the source tree. It would not be annoying to add "$(srctree)/" all the time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kconfig never defines CONFIG_* as 'n'. Now obj-n is only used in firmware/Makefile and it can be replaced with obj-.

| * | kconfig/lxdialog: get ncurses CFLAGS with pkg-configBjørn Forsman2014-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes "make menuconfig" also work on systems where ncurses is not installed in a standard location (such as on NixOS). This patch changes ccflags() so that it tries pkg-config first, and only if pkg-config fails does it go back to the fallback/manual checks. This is the same algorithm that ldflags() already uses.

| * | kconfig: nconfig: fix multi-byte UTF handlingBrian Norris2014-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Kconfig descriptions that use multi-byte UTF-8 characters (such as MTD_NAND_CAFE) will have their menu entries dropped from the 'make nconfig' ncurses menu, and all subsequent entries in the same window will be omitted. This seems to be due to the ncurses 'menu' library, which does not traditionally handle UTF-8 >8-bit characters properly. The ncursesw library ('w' is for "wide") is written to handle these UTF-8 characters, and is practically a drop-in replacement at the source level. Use it by default, if available.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The comment in scripts/Makefile.build says as follows: We would rather have a list of rules like foo.o: $(foo-objs) but that's not so easy, so we rather make all composite objects depend on the set of all their parts This commit makes it possible! For example, assume a Makefile like this obj-m = foo.o bar.o foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this patch, foo.o depends on all of foo1.o foo2.o bar1.o bar2.o. It looks funny that foo.o is regenerated when bar1.c is updated. Now we can handle the dependency of foo.o and bar.o separately.
