2015-12-09genksyms: Handle string literals with spaces in reference filesMichal Marek
The reference files use spaces to separate tokens, however, we must preserve spaces inside string literals. Currently the only case in the tree is struct edac_raw_error_desc in <linux/edac.h>: $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes $ mv drivers/edac/amd64_edac.{symtypes,symref} $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes drivers/edac/amd64_edac.c:527: warning: amd64_get_dram_hole_info: modversion changed because of changes in struct edac_raw_error_desc Signed-off-by: Michal Marek <mmarek@suse.com>
2015-08-20genksyms: Regenerate parserMichal Marek
Rebuild the parser after commit 1c722503fa81 (genksyms: Duplicate function pointer type definitions segfault), using bison 2.7. Signed-off-by: Michal Marek <mmarek@suse.com>
2015-08-20genksyms: Duplicate function pointer type definitions segfaultRichard Yao
I noticed that genksyms will segfault when it sees duplicate function pointer type declaration when I placed the same function pointer definition in two separate headers in a local branch as an intermediate step of some refactoring. This can be reproduced by piping the following minimal test case into `genksyms -r /dev/null` or alternatively, putting it into a C file attempting a build: typedef int (*f)(); typedef int (*f)(); Attaching gdb to genksyms to understand this failure is useless without changing CFLAGS to emit debuginfo. Once you have debuginfo, you will find that the failure is that `char *s` was NULL and the program executed `while(*s)`. At which point, further debugging requires familiarity with compiler front end / parser development. What happens is that flex identifies the first instance of the token "f" as IDENT and the yacc parser adds it to the symbol table. On the second instance, flex will identify "f" as TYPE, which triggers an error case in the yacc parser. Given that TYPE would have been IDENT had it not been in the symbol table, the the segmentaion fault could be avoided by treating TYPE as IDENT in the affected rule. Some might consider placing identical function pointer type declarations in different headers to be poor style might consider a failure to be beneficial. However, failing through a segmentation fault makes the cause non-obvious and can waste the time of anyone who encounters it.

2014-04-03genksyms: fix typeof() handlingJan Beulich
Recent increased use of typeof() throughout the tree resulted in a number of symbols (25 in a typical distro config of ours) not getting a proper CRC calculated for them anymore, due to the parser in genksyms not coping with several of these uses (interestingly in the majority of [if not all] cases the problem is due to the use of typeof() in code preceding a certain export, not in the declaration/definition of the exported function/object itself; I wasn't able to find a way to address this more general parser shortcoming). The use of parameter_declaration is a little more relaxed than would be ideal (permitting not just a bare type specification, but also one with identifier), but since the same code is being passed through an actual compiler, there's no apparent risk of allowing through any broken code. Otoh using parameter_declaration instead of the ad hoc "decl_specifier_seq '*'" / "decl_specifier_seq" pair allows all types to be handled rather than just plain ones and pointers to plain ones.

2013-03-20genksyms: pass symbol-prefix instead of archJames Hogan
Pass symbol-prefix to genksyms instead of arch, so that the decision what symbol prefix to use is kept in one place. Basically genksyms used to take a -a $ARCH argument and it used that to determine whether to add an underscore symbol prefix. It's now changed to take a -s $SYMBOL_PREFIX argument so that the caller decides whether a symbol prefix is required. The build system then uses CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX to determine whether to pass the argument.

2011-03-17genksyms: Track changes to enum constantsMichal Marek
Enum constants can be used as array sizes; if the enum itself does not appear in the symbol expansion, a change in the enum constant will go unnoticed. Example patch that changes the ABI but does not change the checksum with current genksyms: | enum e { | E1, | E2, |+ E3, | E_MAX | }; | | struct s { | int a[E_MAX]; | } | | int f(struct s *s) { ... } | EXPORT_SYMBOL(f) Therefore, remember the value of each enum constant and expand each occurence to <constant> <value>. The value is not actually computed, but instead an expression in the form (last explicitly assigned value) + N is used. This avoids having to parse and semantically understand whole of C.

2008-12-19allow stripping of generated symbols under CONFIG_KALLSYMS_ALLJan Beulich
Building upon parts of the module stripping patch, this patch introduces similar stripping for vmlinux when CONFIG_KALLSYMS_ALL=y. Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64) kernels I tested with. The patch also does away with the need to special case the kallsyms- internal symbols by making them available even in the first linking stage. While it is a generated file, the patch includes the changes to scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure here is.

2008-12-19kbuild: strip generated symbols from *.koJan Beulich
This patch changes the way __crc_ symbols are being resolved from using ld to do so to using the assembler, thus allowing these symbols to be marked local (the linker creates then as global ones) and hence allow stripping (for modules) or ignoring (for vmlinux) them. While at this, also strip other generated symbols during module installation. One potentially debatable point is the handling of the flags passeed to gcc when translating the intermediate assembly file into an object: passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to gas whenever is sees any -g* option, even for -g0, and despite the fact that the compiler would have already produced all necessary debug info in the C->assembly translation phase. I took the approach of just filtering out all -g* options, but an alternative to such negative filtering might be to have a positive filter which might, in the ideal case allow just all the -Wa,* options to pass through.

2008-12-03genksyms: allow to ignore symbol checksum changesAndreas Gruenbacher
This adds an "override" keyword for use in *.symvers / *.symref files. When a symbol is overridden, the symbol's old definition will be used for computing checksums instead of the new one, preserving the previous checksum. (Genksyms will still warn about the change.) This is meant to allow distributions to hide minor actual as well as fake ABI changes. (For example, when extra type information becomes available because additional headers are included, this may change checksums even though none of the types used have actully changed.) This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the code, which are currently used in some vendor kernels to work around checksum changes.

2008-12-03genksyms: track symbol checksum changesAndreas Gruenbacher
Sometimes it is preferable to avoid changes of exported symbol checksums (to avoid breaking externally provided modules). When a checksum change occurs, it can be hard to figure out what caused this change: underlying types may have changed, or additional type information may simply have become available at the point where a symbol is exported. Add a new --reference option to genksyms which allows it to report why checksums change, based on the type information dumps it creates with the --dump-types flag. Genksyms will read in such a dump from a previous run, and report which symbols have changed (and why). The behavior can be controlled for an entire build as follows: If KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes dump files. If any *.symref files exist, those will be used as the reference to check against. If KBUILD_PRESERVE is set, checksum changes will fail the build.

2008-07-31kbuild: genksyms parser: fix the __attribute__ ruleAndreas Gruenbacher
We are having two kinds of problems with genksyms today: fake checksum changes without actual ABI changes, and changes which we would rather like to ignore (such as an additional field at the end of a structure that modules are not supposed to touch, for example). I have thought about ways to improve genksyms and compute checksums differently to avoid those problems, but in the end I don't see a fundamentally better way. So here are some genksyms patches for at least making the checksums more easily manageable, if we cannot fully fix them. In addition to the bugfixes (the first two patches), this allows genksyms to track checksum changes and report why a checksum changed (third patch), and to selectively ignore changes (fourth patch). This patch: Gcc __attribute__ definitions may occur repeatedly, e.g., static int foo __attribute__((__used__)) __attribute__((aligned (16))); The genksyms parser does not understand this, and generates a syntax error. Fix this case.

This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2006-06-24kbuild: support for %.symtypes filesAndreas Gruenbacher
Here is a patch that adds a new -T option to genksyms for generating dumps of the type definition that makes up the symbol version hashes. This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes.
