2018-05-29kconfig: make default prompt of mainmenu less specificMasahiro Yamada
If "mainmenu" is not specified, "Linux Kernel Configuration" is used as a default prompt. Given that Kconfig is used in other projects than Linux, let's use a more generic prompt, "Main menu".

2018-05-29kconfig: remove string expansion in file_lookup()Masahiro Yamada
There are two callers of file_lookup(), but there is no more reason to expand the given path. [1] zconf_initscan() This is used to open the first Kconfig. sym_expand_string_value() has never been used in a useful way here; before opening the first Kconfig file, obviously there is no symbol to expand. If you use expand_string_value() instead, environments in KBUILD_KCONFIG would be expanded, but I do not see practical benefits for that. [2] zconf_nextfile() This is used to open the next file from 'source' statement. Symbols in the path like "arch/$SRCARCH/Kconfig" needed expanding, but it was replaced with the direct environment expansion. The environment has already been expanded before the token is passed to the parser. By the way, file_lookup() was already buggy; it expanded a given path, but it used the path before expansion for look-up: if (!strcmp(name, file->name)) { Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org> Reviewed-by: Ulf Magnusson <ulfalizer@gmail.com>
2018-05-29kconfig: reference environment variables directly and remove 'option env='Masahiro Yamada
To get access to environment variables, Kconfig needs to define a symbol using "option env=" syntax. It is tedious to add a symbol entry for each environment variable given that we need to define much more such as 'CC', 'AS', 'srctree' etc. to evaluate the compiler capability in Kconfig. Adding '$' for symbol references is grammatically inconsistent. Looking at the code, the symbols prefixed with 'S' are expanded by: - conf_expand_value() This is used to expand 'arch/$ARCH/defconfig' and 'defconfig_list' - sym_expand_string_value() This is used to expand strings in 'source' and 'mainmenu' All of them are fixed values independent of user configuration. So, they can be changed into the direct expansion instead of symbols. This change makes the code much cleaner. The bounce symbols 'SRCARCH', 'ARCH', 'SUBARCH', 'KERNELVERSION' are gone. sym_init() hard-coding 'UNAME_RELEASE' is also gone. 'UNAME_RELEASE' should be replaced with an environment variable. ARCH_DEFCONFIG is a normal symbol, so it should be simply referenced without '$' prefix. The new syntax is addicted by Make. The variable reference needs parentheses, like $(FOO), but you can omit them for single-letter variables, like $F. Yet, in Makefiles, people tend to use the parenthetical form for consistency / clarification. At this moment, only the environment variable is supported, but I will extend the concept of 'variable' later on. The variables are expanded in the lexer so we can simplify the token handling on the parser side. For example, the following code works. [Example code] config MY_TOOLCHAIN_LIST string default "My tools: CC=$(CC), AS=$(AS), CPP=$(CPP)" [Result] $ make -s alldefconfig && tail -n 1 .config CONFIG_MY_TOOLCHAIN_LIST="My tools: CC=gcc, AS=as, CPP=gcc -E" Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org>
2018-05-29kbuild: remove kbuild cacheMasahiro Yamada
The kbuild cache was introduced to remember the result of shell commands, some of which are expensive to compute, such as $(call cc-option,...). However, this turned out not so clever as I had first expected. Actually, it is problematic. For example, "$(CC) -print-file-name" is cached. If the compiler is updated, the stale search path causes build error, which is difficult to figure out. Another problem scenario is cache files could be touched while install targets are running under the root permission. We can patch them if desired, but the build infrastructure is getting uglier and uglier. Now, we are going to move compiler flag tests to the configuration phase. If this is completed, the result of compiler tests will be naturally cached in the .config file. We will not have performance issues of incremental building since this testing only happens at Kconfig time. To start this work with a cleaner code base, remove the kbuild cache first. Revert the following commits: Commit 9a234a2e3843 ("kbuild: create directory for make cache only when necessary") Commit e17c400ae194 ("kbuild: shrink .cache.mk when it exceeds 1000 lines") Commit 4e56207130ed ("kbuild: Cache a few more calls to the compiler") Commit 3298b690b21c ("kbuild: Add a cache for generated variables") Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org>
2018-05-28trace: Use -mcount-record for dynamic ftraceAndi Kleen
gcc 5 supports a new -mcount-record option to generate ftrace tables directly. This avoids the need to run record_mcount manually. Use this option when available. So far doesn't use -mcount-nop, which also exists now. This is needed to make ftrace work with LTO because the normal record-mcount script doesn't run over the link time output. It should also improve build times slightly in the general case.

2018-05-28kconfig: refactor ncurses package checks for building mconf and nconfMasahiro Yamada
The mconf (or its infrastructure, lxdiaglog) depends on the ncurses. Move and rename check-lxdialog.sh to mconf-cfg.sh to make it work in the same way as for qconf and gconf. This commit fixes some more weirdnesses. The nconf also needs ncurses packages. HOSTLOADLIBES_nconf is set to the libraries needed for nconf, but the cflags is not explicitly set. Actually, nconf relies on the check-lxdialog.sh for the proper cflags: HOST_EXTRACFLAGS += $(shell $(CONFIG_SHELL) $(check-lxdialog) -ccflags) \ -DLOCALE The code above passes the ncurses flags to all objects, even for conf, qconf, gconf. Let's pass the ncurses flags only to mconf and nconf. Currently, the presence of ncurses is not checked for nconf. Let's show a prompt like the mconf case. According to Randy's report, the shell scripts still need to carry the fallback code in case the pkg-config fails to find the ncurses packages.

2018-05-17bpf: change eBPF helper doc parsing script to allow for smaller indentQuentin Monnet
Documentation for eBPF helpers can be parsed from bpf.h and eventually turned into a man page. Commit 6f96674dbd8c ("bpf: relax constraints on formatting for eBPF helper documentation") changed the script used to parse it, in order to allow for different indent style and to ease the work for writing documentation for future helpers. The script currently considers that the first tab can be replaced by 6 to 8 spaces. But the documentation for bpf_fib_lookup() uses a mix of tabs (for the "Description" part) and of spaces ("Return" part), and only has 5 space long indent for the latter. We probably do not want to change the values accepted by the script each time a new helper gets a new indent style. However, it is worth noting that with those 5 spaces, the "Description" and "Return" part *look* aligned in the generated patch and in `git show`, so it is likely other helper authors will use the same length. Therefore, allow for helper documentation to use 5 spaces only for the first indent level.

2018-05-05gcc-plugins: fix build condition of SANCOV pluginMasahiro Yamada
Since commit d677a4d60193 ("Makefile: support flag -fsanitizer-coverage=trace-cmp"), you miss to build the SANCOV plugin under some circumstances. CONFIG_KCOV=y CONFIG_KCOV_ENABLE_COMPARISONS=y Your compiler does not support -fsanitize-coverage=trace-pc Your compiler does not support -fsanitize-coverage=trace-cmp Under this condition, $(CFLAGS_KCOV) is not empty but contains a space, so the following ifeq-conditional is false. ifeq ($(CFLAGS_KCOV),) Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to gcc-plugin-y while the SANCOV plugin is necessary as an alternative means.

2018-05-04MAINTAINERS & files: Canonize the e-mails I use at filesMauro Carvalho Chehab
From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

Commit 7840fea200cd ("kbuild: Fix computing srcversion for modules") fixed the comment above parse_source_files to refer to the new source_ line, but left this one behind that could still give the impression that drivers/net/dummy.c appears in the deps_ variable.

2018-05-02bpf: relax constraints on formatting for eBPF helper documentationQuentin Monnet
The Python script used to parse and extract eBPF helpers documentation from include/uapi/linux/bpf.h expects a very specific formatting for the descriptions (single dot represents a space, '>' stands for a tab): /* ... *.int bpf_helper(list of arguments) *.> Description *.> > Start of description *.> > Another line of description *.> > And yet another line of description *.> Return *.> > 0 on success, or a negative error in case of failure ... */ This is too strict, and painful for developers who wants to add documentation for new helpers. Worse, it is extremely difficult to check that the formatting is correct during reviews. Change the format expected by the script and make it more flexible. The script now works whether or not the initial space (right after the star) is present, and accepts both tabs and white spaces (or a combination of both) for indenting description sections and contents. Concretely, something like the following would now be supported: /* ... *int bpf_helper(list of arguments) *......Description *.> > Start of description... *> > Another line of description *..............And yet another line of description *> Return *.> ........0 on success, or a negative error in case of failure ... */ While at it, remove unnecessary carets from each regex used with match() in the script. They are redundant, as match() tries to match from the beginning of the string by default. v2: Remove unnecessary caret when a regex is used with match().
