From f0778c8c41001783d4074e34efc7d3e632d87ee3 Mon Sep 17 00:00:00 2001 From: Aristeu Rozanski Date: Thu, 6 May 2010 12:48:34 -0400 Subject: kconfig: introduce nonint_oldconfig and loose_nonint_oldconfig 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.

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.

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.

The initial pass at the generic ABI assumed that wait4() could be easily expressed using waitid(). Although it's true that wait4() can be built on waitid(), it's awkward enough that it makes more sense to continue to include wait4 in the generic syscall ABI. Since there is already a deprecated wait4 in the ABI, this change converts that wait4 into old_wait, and puts wait4 in the next available slot for new supported syscalls, after the platform-specific syscalls at number 260.

Currently, the "depends on" clauses are used in calculating the visibility but they do not affect the reverse dependencies in any way. The patch introduces additional tracking of the "depends on" statements and prints a warning on selecting an option if its direct dependencies are not met.

However, I think the patch is still a good idea, to avoid future problems if _mcount were to ever have its address taken in normal code. This is what I originally saw: Although arch/mips/kernel/ftrace.c is built without -pg, and thus contains no calls to _mcount, it does use the address of _mcount in ftrace_make_nop(). This was causing relocations to be emitted for _mcount which recordmcount.pl erronously took to be _mcount call sites. The result was that the text of ftrace_make_nop() would be patched with garbage leading to a system crash. In non-module code, all _mcount call sites will have R_MIPS_26 relocations, so we restrict $mcount_regex to only match on these.

Take the following Kconfig as an example: config MODULES def_bool y config FOO def_tristate m With no .config, the following configuration is generated: CONFIG_MODULES=y CONFIG_FOO=y With an empty .config, the following: CONFIG_MODULES=y CONFIG_FOO=m Tristate choice statements can also exhibit the problem, due to having an implicit rev_dep (select) containing "m". The problem is that MODULES is never evaluted in conf_read_simple() unless there's a .config. The following patch fixes this.

charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

In a very annoying way. I just did a quick git bisect. It's introduced by commit 4062f1a4c030 ("kconfig: use long options in conf") by Sam Ravnborg. Apparently that thing is totally buggy, and doesn't just change the option names, but actively breaks them. The old behaviour (from years ago) were reintroduced by accident.

Consider following example: config M def_bool y option modules choice prompt "choice list" config A tristate "a" config B tristate "b" endchoice With a defconfig like this: CONFIG_M=y CONFIG_A=y The resulting configuration would have CONFIG_A=m which was unexpected. The problem was not not all choice values were set and thus kconfig calculated a wrong value. The fix is to set all choice values when we read a defconfig files. conf_set_all_new_symbols() is refactored such that random choice values are now handled by a dedicated function. And new choice values are set by set_all_choice_values(). This was not the minimal fix, but the fix that resulted in the most readable code.

Consider following minimal configuration: $cat Kconfig choice prompt "choice" optional config A bool "a" config B bool "b" endchoice $cat .config | grep -v ^# CONFIG_A=y $conf --savedefconfig=defconfig Kconfig would before this fix result in an empty file, because kconfig would assume that CONFIG_A=y is a default value. But because the choice is optional the default is that both A and B are =n. Fix so we handle optional choices correct.

This is due to show_help() passing an empty string to show_scroll_win()'s 3rd argument. The option really does have help though, but it isn't a config symbol, so just add the help text for the option, and don't try to add anything else like the config option name.

To compute the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow ncursesw to be used as a replacement ncurses. However, when checking what header file to include, we do not check /usr/include/ncursesw directory. Add /usr/include/ncursesw to the list of directories that are checked. With this patch, on my Debian Lenny box with libncursesw5-dev package but not libncurses5-dev package, I can say "make menuconfig".

Based on a new 'asm goto' inline assembly gcc mechanism, we can now branch to labels from an 'asm goto' statment. This allows us to create a 'no-op' fastpath, which can subsequently be patched with a jump to the slowpath code. This is useful for code which might be rarely used, but which we'd like to be able to call, if needed. Tracepoints are the current usecase that these are being implemented for. Acked-by: David S.

After verifying this works, other archs can add: HAVE_C_MCOUNT_RECORD in its Kconfig and it will use the C version of recordmcount instead of the perl version.

This was due to the need of using the 32 and 64 bit elf structures. This patch consolidates the two by using macros to define the 32 and 64 bit names in a recordmcount.h file, and then by just defining a RECORD_MCOUNT_64 macro and including recordmcount.h twice we create the funtions for both the 32 bit version as well as the 64 bit version using one code source.

But because it references mcount(), the mcount() address is placed in the relocation table. The C version of recordmcount reads the relocation table of all object files, and it will add all references to mcount to the __mcount_loc table that is used to find the places that call mcount() and change the call to a nop. When recordmcount finds the mcount reference in kernel/trace/ftrace.o, it saves that location even though the code is not a call, but references mcount as data. On boot up, when all calls are converted to nops, the code has a safety check to determine what op code it is actually replacing before it replaces it. If that op code at the address does not match, then a warning is printed and the function tracer is disabled. The reference to mcount in ftrace.c, causes this warning to trigger, since the reference is not a call to mcount(). The ftrace.c file is not compiled with the -pg flag, so no calls to mcount() should be expected. This patch simply makes recordmcount.c skip the kernel/trace/ftrace.c file. This was the same solution used by the perl version of recordmcount.

The build process has a special file: scripts/mod/empty.o. This is built from empty.c which is literally an empty file (except for a single comment). This file is used to find information about the target elf format, like endianness and word size. The problem comes up when we need to build recordmcount. The build process requires that empty.o is built first. The build rules for empty.o will try to execute recordmcount on the empty.o file. We get an error that recordmcount does not exist.

But, the default C version of recordmcount records all of the _mcount symbols, so, we must filter the 2nd _mcount like the Perl version of recordmcount does. The C version of recordmcount copes with the symbols before they are linked, So It doesn't know the type of the symbols and therefore can not filter the symbols as the Perl version of recordmcount does. But as we can see above, the 2nd _mcount symbols of the long call alawys follows the 1st _mcount symbol of the same long call, which means the offset from the 1st to the 2nd is fixed, it is 0x10-0xc = 4 here, 4 is the length of the 1st load instruciton, for MIPS has fixed length of instructions, this offset is always 4. And as we know, the _mcount is inserted into the entry of every kernel function, the offset between the other _mcount's is expected to be always bigger than 4. So, to filter the 2ns _mcount symbol of the long call, we can simply check the offset between two _mcount symbols, If it is 4, then, filter the 2nd _mcount symbol. To avoid touching too much code, an 'empty' function fn_is_fake_mcount() is added for all of the archs, and the specific archs can override it via chaning the function pointer: is_fake_mcount in do_file() with the e_machine. e.g. This patch adds MIPS_is_fake_mcount() to override the default fn_is_fake_mcount() pointed by is_fake_mcount. This fn_is_fake_mcount() checks if the _mcount symbol is fake, e.g. the 2nd _mcount symbol of the long call is fake, for there are 2 _mcount symbols mapped to one real mcount call, so, one of them is fake and must be filtered. This fn_is_fake_mcount() is called in sift_rel_mcount() after finding the _mcount symbols and before adding the _mcount symbol into mrelp, so, it can prevent the fake mcount symbol going into the last __mcount_loc table.
