2008-04-29update checkpatch.pl to version 0.18Andy Whitcroft1-5/+20
This version brings a few fixes for the extern checks, and a couple of new checks. Of note: - false is now recognised as a 0 assignment in static/external assignments, - printf format strings including %L are reported, - a number of fixes for the extern in .c file detector which had temporarily lost its ability to detect variables; undetected due to the loss of its test. Andy Whitcroft (8): Version: 0.18 false should trip 0 assignment checks tests: reinstate missing tests tests: allow specification of the file extension for a test fix extern checks for variables check for and report %Lu, %Ld, and %Li ensure we only start a statement on lines with some content extern spacing Signed-off-by: Andy Whitcroft <apw@shadowen.org> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-04-29update checkpatch.pl to version 0.17Andy Whitcroft1-41/+90
This version brings improvements to external declaration detection, fixes to quote tracking, fixes to unary tracking, some clarification of wording, and the usual slew of fixes for false positives. Of note: - much better unary tracking across preprocessor directives - UTF8 checks highlight the character at fault - widening of mutex detection Andy Whitcroft (17): Version: 0.17 values: __attribute__ carries through the previous type quotes: should only follow "positive" lines clarify the indent tabs over spaces wording loosen NR_CPUS check for array range initialisers detect external function declarations without an extern prefix function declaration arguments should be with the identifier DEFINE_MUTEX should report in line with struct mutex NR_CPUS is valid in preprocessor statements comment detection should not start on the @@ line types: add support for #undef tighten mutex/completion reports to usage allow export of function pointers values: preprocessor #define is out of line maintain values values: #define does not always have parentheses unary '*' may be const utf8 checks should report location of the invalid character Wolfram Sang (1): make checkpatch.pl really skip <asm/irq.h> Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-04-28kconfig: add named choice groupRoman Zippel6-223/+206
As choice dependency are now fully checked, it's quite easy to add support for named choices. This lifts the restriction that a choice value can only appear once, although it still has to be within the same group, but multiple choices can be joined by giving them a name. While at it I cleaned up a little the choice type logic to simplify it a bit. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-04-28kernel-doc: detect/prevent duplicate doc section namesRandy Dunlap1-7/+13
I saw this problem recently. With this kernel-doc: * Note: some important info * * Note: other important info kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash key for storing the descriptive text ("blah important info"). It is (was) possible to have duplicate (colliding) section names, without any kind of warning or error. kernel-doc happily used the latter descriptive text for all instances of printing the <section-name> descriptive text and the former important info was lost. One way to "fix" this is to modify the kernel-doc comments, e.g.: * Note1: foo bar * * Note.2: blah zay For now, kernel-doc will signal an error when it sees colliding section names like this.

2008-04-25kbuild: support loading extra symbols in modpostRichard Hacker1-1/+22
This patch adds a new command line option -E to modpost, expecting a symbol file as an argument which is read prior to symbol processing. -E can be supplied multiple times for as many files as is needed. When building kernel modules that depend on other modules not in the main kernel tree, modpost complains about undefined symbols: # make -C /path/to/linux/kernel M=/path/to/my/module ... Building modules, stage 2. .... WARNING: "rt_copy_buf" [/home/rich/osc_etl_rtw/osc_kmod.ko] undefined! ...etc This situation occurs when modpost processes the new module's symbols. When it finds symbols not exported by the mainline kernel, it issues this warning. The patch adds a new command line option -e to modpost which expects a symbol file as an argument. The symbols listed in this file are added to modpost's symbol tables during startup. -e can be supplied as often as required. This patch works together with the second patch. It introduces a new make variable, KBUILD_EXTRA_SYMBOLS, which is used when calling modpost. Signed-off-by: Richard Hacker <lerichi@gmx.net> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2008-04-19PNP: add all PNP card device id's as individual aliasesKay Sievers1-13/+44
The current PNP combined card + devices module aliase can never ever match anything, because these values are not available all at the same time to request a module. Instead of adding the combined alias, we add the device id's all as individual aliases. Device id's are exported by the PNP bus and can now properly used to request the loading of a matching module. The module snd-sbawe currently exports aliases, which can never match anything: alias: pnp:cCTLXXXXdCTL0045dCTL0022* alias: pnp:cCTLXXXXdCTL0044dCTL0023* alias: pnp:cCTLXXXXdCTL0042dCTL0022* alias: pnp:cCTLXXXXdCTL0041dCTL0021* alias: pnp:cCTLXXXXdCTL0031dCTL0021* alias: pnp:cCTL00eddCTL0041dCTL0070* alias: pnp:cCTL00e9dCTL0045dCTL0022* alias: pnp:cCTL00e4dCTL0045dCTL0022* alias: pnp:cCTL00c7dCTL0045dCTL0022* alias: pnp:cCTL00c5dCTL0045dCTL0022* alias: pnp:cCTL00c3dCTL0045dCTL0022* alias: pnp:cCTL00c1dCTL0042dCTL0022* alias: pnp:cCTL00b2dCTL0044dCTL0023* alias: pnp:cCTL009edCTL0044dCTL0023* alias: pnp:cCTL009ddCTL0042dCTL0022* alias: pnp:cCTL009fdCTL0041dCTL0021* alias: pnp:cCTL009cdCTL0041dCTL0021* alias: pnp:cCTL009adCTL0041dCTL0021* alias: pnp:cCTL0054dCTL0031dCTL0021* alias: pnp:cCTL0048dCTL0031dCTL0021* alias: pnp:cCTL0047dCTL0031dCTL0021* alias: pnp:cCTL0046dCTL0031dCTL0021* alias: pnp:cCTL0045dCTL0031dCTL0021* alias: pnp:cCTL0044dCTL0031dCTL0021* alias: pnp:cCTL0043dCTL0031dCTL0021* alias: pnp:cCTL0042dCTL0031dCTL0021* alias: pnp:cCTL0039dCTL0031dCTL0021* alias: pnp:cCTL0035dCTL0031dCTL0021* With this patch it exports only the device id's, as properly matchable aliases: alias: pnp:dCTL0070* alias: pnp:dCTL0045* alias: pnp:dCTL0023* alias: pnp:dCTL0044* alias: pnp:dCTL0022* alias: pnp:dCTL0042* alias: pnp:dCTL0041* alias: pnp:dCTL0021* alias: pnp:dCTL0031* Now, the exported value of the PNP bus can be used to autoload a matching module: $ modprobe --first-time -n -v pnp:dCTL0045 insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-rawmidi.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/mpu401/snd-mpu401-uart.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-hwdep.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb-common.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-csp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-dsp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/opl3/snd-opl3-lib.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sbawe.ko $ grep CTL0045 /sys/bus/pnp/devices/*/id /sys/bus/pnp/devices/01:01.00/id:CTL0045 Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-02-23kernel-doc: fix function-pointer-parameter parsingRichard Kennedy1-3/+3
When running "make htmldocs" I'm seeing some non-fatal perl errors caused by trying to parse the callback function definitions in blk-core.c. The errors are "Use of uninitialized value in concatenation (.)..." in combination with: Warning(linux-2.6.25-rc2/block/blk-core.c:1877): No description found for parameter '' The function pointers are defined without a * i.e. int (drv_callback)(struct request *) The compiler is happy with them, but kernel-doc isn't. This patch teaches create_parameterlist in kernel-doc to parse this type of function pointer definition, but is it the right way to fix the problem ? The problem only seems to occur in blk-core.c. However with the patch applied, kernel-doc finds the correct parameter description for the callback in blk_end_request_callback, which is doesn't normally. I thought it would be a bit odd to change to code to use the more normal form of function pointers just to get the documentation to work, so I fixed kernel-doc instead - even though this is teaching it to understand code that might go away (The comment for blk_end_request_callback says that it should not be used and will removed at some point).

2008-02-13Linux Kernel Markers: create modpost fileMathieu Desnoyers3-1/+177
This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

2008-02-13kconfig: fix select in combination with defaultRoman Zippel1-13/+21
> The attached .config (with current -git) results in a compile > error since it contains: > > CONFIG_X86=y > # CONFIG_EMBEDDED is not set > CONFIG_SERIO=m > CONFIG_SERIO_I8042=y > > Looking at drivers/input/serio/Kconfig I simply don't get how this > can happen. You've hit the rather subtle rules of select vs default. What happened is that SERIO is selected to m, but SERIO_I8042 isn't selected so the default of y is used instead. We already had the problem in the past that select and default don't work well together, so this patch cleans this up and makes the rule hopefully more straightforward. Basically now the value is calculated like this: (value && dependency) || select where the value is the user choice (if available and the symbol is visible) or default. In this case it means SERIO and SERIO_I8042 are both set to y due to their default and if SERIO didn't had the default, then the SERIO_I8042 value would be limited to m due to the dependency. I tested this patch with more 10000 random configs and above case is the only the difference that showed up, so I hope there is nothing that depended on the old more complex and subtle rules.

Mostly these are fixes for false positives, both through improvments to unary checks and possible type detection. It also brings new checks for while location and CVS keywords. Of note: - a number of fixes to unary detection - detection of a number of new forms of types to improve type matching - better inline handling - recognision of '%' as an operator Andy Whitcroft (28): Version: 0.13 unary detection: maintain bracket state across lines move to pre-sanitising the entire file the text of a #error statement should be treated like it is in quotes line sanitisation needs to target double backslash correctly tighten comment guestimation for lines starting ' * ' debug: add a debug framework prevent unclosed single quotes from spreading add % as an operator the text of a #warning statement should be treated like it is in quotes possible matching applies in typedefs single statement block checks must not trigger when two or more statements possible types: local variables may also be const treat inline as a type attribute to even when out of place possible types: sparse annotations are valid indicators possible types: beef up the possible type testing check for hanging while statements on the wrong line utf8 checks need to occur against the raw lines function brace checks should use any whitespece matches comments should take up space in the line when sanitised remove debugging from if assignment checks possible types -- ensure we detect all pointer casts fix tests for function spacing in the presence of #define clean up the UTF-8 error message to be clearer test-lib: invert the status report, output success counts detect and report CVS keywords tests: break out tests Add $Id$ to the CVS keyword checks Benny Halevy (1): checkpatch.pl: recognize the #elif preprocessor directive Geert Uytterhoeven (1): print the filenames of patches where available Mauro Carvalho Chehab (1): Fix missing \n in checkpatch.pl Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-02-07kernel-doc: warn on badly formatted short descriptionRandy Dunlap1-0/+8
Make kernel-doc warn when a function/struct/union/typedef does not contain a properly formatted short description, such as: * scsi_devinfo: set up the dynamic device list or * scsi_devinfo - This warning is only generated when verbose (-v) mode is used. Also explain the -v command line option in the -h output.

2008-02-06Claim maintainership for block2mtd and update email addressesJoern Engel1-1/+1
I have been prime author and maintainer of block2mtd from day one, but neither MAINTAINERS nor the module source makes this fact clear. And while I'm at it, update my email addresses tree-wide, as the old address currently bounces and change my name to "joern" as unicode will likely continue to cause trouble until the end of this century.

2008-02-06kallsyms should prefer non weak symbolsPaulo Marques1-3/+34
When resolving symbol names from addresses with aliased symbol names, kallsyms_lookup always returns the first symbol, even if it is a weak symbol. This patch changes this by sorting the symbols with the weak symbols last before feeding them to the kernel. This way the kernel runtime isn't changed at all, only the kallsyms build system is changed. Another side effect is that the symbols get sorted by address, too. So, even if future binutils version have some bug in "nm" that makes it fail to correctly sort symbols by address, the kernel won't be affected by this. Mathieu says: I created a module in LTTng that uses kallsyms to get the symbol corresponding to a specific system call address. Unfortunately, all the unimplemented syscalls were all referring to the (same) weak symbol identifying an unrelated system call rather that sys_ni (or whatever non-weak symbol would be expected). Kallsyms was dumbly returning the first symbol that matched. This patch makes sure kallsyms returns the non-weak symbol when there is one, which seems to be the expected result.

2008-02-06remove support for un-needed _extratext sectionRobin Getz1-14/+10
When passing a zero address to kallsyms_lookup(), the kernel thought it was a valid kernel address, even if it is not. This is because is_ksym_addr() called is_kernel_extratext() and checked against labels that don't exist on many archs (which default as zero). Since PPC was the only kernel which defines _extra_text, (in 2005), and no longer needs it, this patch removes _extra_text support.

2008-02-03kbuild: do not warn about __*init/__*exit symbols being exportedSam Ravnborg1-1/+1
We have several legitimate uses where we export symbols annotated with one of: __devinit, __cpuinit, __meminit and their exit counterpart. So let's stop warning about those being exported in favour of adding all sorts of workaround to silence the warning. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-02-03kconfig: ignore select of unknown symbolSam Ravnborg1-6/+3
We have had warnings for a long time about select of unknow symbol but the warnings does not really makes sense since we may select a symbol that is relevant and defined in one arch but not in another arch. And as long as we do not use a common set of Kconfig files for all archs lets just ignore this case. Previously we have used this to find bad uses of select but we need a more relaible method to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

2008-02-01USB: handle idVendor of 0x0000Greg Kroah-Hartman1-1/+1
Some crazy devices in the wild have a vendor id of 0x0000. If we try to add a module alias with this id, we just can't do it due to a check in the file2alias.c file. Change the test to verify that both the vendor and product ids are 0x0000 to show a real "blank" module alias. Note, the module-init-tools package also needs to be changed to properly generate the depmod tables.

2008-01-28kbuild: warn about ld added unique sectionsSam Ravnborg1-2/+40
If there is a mixture of specifying sections for code in gcc and assembler then if the assembler code do not add the "ax" flags the linker will see this as two different sections and generate unique sections for each. ld does so by adding a dot and a number. Teach modpost to warn if a section shows up that match this pattern - but do this only for non-debug sections. It will result in warnings like this: WARNING: vmlinux.o (.sched.text.1): unexpected section name. The (.[number]+) following section name are ld generated and not expected. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files. All warnings seen with a defconfig build for: x86 (32+64bit) and sparc64 has been fixed (via respective maintainers). arm, powerpc (64 bit), s390 (32 bit), ia64, alpha, sh4 checked - no warnings seen with a defconfig build.
