* scripts: add "prune-kernel" script to clean up old kernel imagesJ. Bruce Fields2016-02-091-0/+20
| | | | | | | | | | | | | | | | | | | | | | | Long ago, Dave Jones complained about CONFIG_LOCALVERSION_AUTO: "I don't use the auto config, because I end up filling up /boot unless I go through and clean them out by hand every time I install a new one (which I do probably a dozen or so times a day). Is there some easy way to prune old builds I'm missing?" To which Bruce replied: "I run this by hand every now and then. I'm probably doing it all wrong" And if he is running it wrong, then so am I - because I've been using this script ever since. It is true that CONFIG_LOCALVERSION_AUTO easily ends up filling your /boot partition if you don't clean up old versions regularly, and this script helps make that easier. Checked with Bruce to see that it's fine to add this to the kernel scripts. Maybe people will come up with enhancements, but more importantly, this way I won't misplace this script whenever I install a new machine and start doing custom kernels for it.

| * powerpc: Simplify module TOC handlingAlan Modra2016-01-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PowerPC64 uses the symbol .TOC. much as other targets use _GLOBAL_OFFSET_TABLE_. It identifies the value of the GOT pointer (or in powerpc parlance, the TOC pointer). Global offset tables are generally local to an executable or shared library, or in the kernel, module. Thus it does not make sense for a module to resolve a relocation against .TOC. to the kernel's .TOC. value. A module has its own .TOC., and indeed the powerpc64 module relocation processing ignores the kernel value of .TOC. and instead calculates a module-local value. This patch removes code involved in exporting the kernel .TOC., tweaks modpost to ignore an undefined .TOC., and the module loader to twiddle the section symbol so that .TOC. isn't seen as undefined. Note that if the kernel was compiled with -msingle-pic-base then ELFv2 would not have function global entry code setting up r2. In that case the module call stubs would need to be modified to set up r2 using the kernel .TOC. value, requiring some of this code to be reinstated. mpe: Furthermore a change in binutils master (not yet released) causes the current way we handle the TOC to no longer work when building with MODVERSIONS=y and RELOCATABLE=n. The symptom is that modules can not be loaded due to there being no version found for TOC.

* | UBSAN: run-time undefined behavior sanity checkerAndrey Ryabinin2016-01-212-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UBSAN uses compile-time instrumentation to catch undefined behavior (UB). Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2]. Article [3] has a bit more details about UBSAN in the GCC.

Check the concatenated variable for args or __VA_ARGS__ and allow those macros to also be reported when they contain a return or goto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Unsigned expressions cannot be lesser than zero. Presence of comparisons 'unsigned (<|<=|>|>=) 0' often indicates a bug, usually wrong type of variable. The patch beside finding such comparisons tries to eliminate false positives, mainly by bypassing range checks. gcc can detect such comparisons also using -Wtype-limits switch, but it warns also in correct cases, making too much noise.

| * tags: Unify emacs and exuberant rulesMichal Marek2016-01-051-93/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The emacs rules were constantly lagging behind the exuberant ones. Use a single set of rules for both, to make the script easier to maintain. The language understood by both tools is basic regular expression with some limitations, which are documented in a comment. To be able to store the rules in an array and easily iterate over it, the script requires bash now. In the exuberant case, the change fixes some false matches in <linux/page-flags.h> and also some too greedy matches in the arguments of the DECLARE_*/DEFINE_* macros. In the emacs case, several previously not working rules are matching now.

| | | | | | | | | | | | | | | | | | | | | | | | This allows to apply the same patters to both source and header files. The effect is mostly visible in the case of DECLARE_BITMAP, but there are small gains all over the place. There is also lots of random changes in the diff, I believe this is simply because there are still lots of unexpanded macros in the code and the C and C++ parsers fail and recover at different points. Also, qconf.h is parsed as C, but that's a negligible regression. Signed-off-by: Michal Marek <mmarek@suse.com>

The command to output MANIFEST becomes: $(cd ..; echo $(cat ../tools/perf/MANIFEST)) Without MANIFEST, the entire kernel source tree is added to the perf source tarball. The *correct* fix is to keep the cd and remove srctree from cat command line since MANIFEST has wildcards that fail to expand working directory isn't srctree. Second, PERF-VERSION-FILE gets not added, because in-tree build path is hardcoded to Makefile: util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null) The PERF-VERSION-GEN needs to be run from tools/perf directory, and the output directory needs to be changed from relative to to absolute. This can be achieved using the $(CURDIR) variable. Also remove the error redirect to /dev/null which hid the error.

These have to be replaced with a parsable version for kernel-doc. For example a simple input like /** * struct something - some test * @members: active members */ struct something { DECLARE_BITMAP(members, MAX_MEMBERS); }; resulted in parsing warnings like warning: No description found for parameter 'MAX_MEMBERS)' warning: Excess struct/union/enum/typedef member 'members' description in 'something' Signed-off-by: Conchúr Navid <conchur@web.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

| * | | scripts/recordmcount.pl: support data in text section on powerpcUlrich Weigand2016-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a text section starts out with a data blob before the first function start label, disassembly parsing doing in recordmcount.pl gets confused on powerpc, leading to creation of corrupted module objects. This was not a problem so far since the compiler would never create such text sections. However, this has changed with a recent change in GCC 6 to support distances of > 2GB between a function and its assoicated TOC in the ELFv2 ABI, exposing this problem. There is already code in recordmcount.pl to handle such data blobs on the sparc64 platform. This patch uses the same method to handle those on powerpc as well.

* | | | modpost: don't add a trailing wildcard for OF module aliasesJavier Martinez Canillas2016-01-151-2/+1

This is also true for OF modaliases since a compatible string is used to define a specific IP hardware block. So the modalias should match a specific compatible string and not attempt to match a compatible string whose name matches the beginning of another one. For example, the following driver module: $ modinfo cros_ec_keyb | grep alias alias: platform:cros-ec-keyb alias: of:N*T*Cgoogle,cros-ec-keyb* will be tried to be loaded for an alias of:N*T*Cgoogle,cros-ec-keyb-v2 but there could be a different driver that supports the device for that compatible string so it's better to remove the trailing wildcard for OF. Also, remove the word "always" from the add_wildcard() function comment since that was carried from the time where a wildcard was always added at the end of the module alias for all the devices.

Currently scripts/ld-version.sh is only being used by MIPS" [ This obviously missed 4.4, so getting merged now in the merge window for 4.5 instead ] * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: ld-version: Fix it on Fedora Fix ld-version.sh to handle large 3rd version part
