2006-09-16[PATCH] Fix 'make headers_check' on biarch architecturesDavid Woodhouse1-3/+5
We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or <asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on whether the file in question existed in the _unexported_ tree, not the exported tree. So if a file was exported to userspace in one asm- directory but not the other, the generated file in asm/ was incorrect. This only changed the failure mode if it _was_ included from a nice #error to a less explicable #include failure -- but it also gave false errors in 'make headers_check' output. Fix it by looking in the right place instead.

2006-08-15[PATCH] PATCH: 1 line 2.6.18 bugfix: modpost-64bit-fix.patchHans de Goede1-1/+1
There is a small but annoying bug in scripts/mod/file2alias.c which causes it to generate invalid aliases for input devices on 64 bit archs. This causes joydev.ko to not be automaticly loaded when inserting a joystick, resulting in a non working joystick (for the average user). In scripts/mod/file2alias.c is the following code for generating the input aliases: static void do_input(char *alias, kernel_ulong_t *arr, unsigned int min, unsigned int max) { unsigned int i; for (i = min; i < max; i++) if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) sprintf(alias + strlen(alias), "%X,*", i); } On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*" for the second etc. However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20 + first entry (hex) ! to the list of hex codes, which is 32 more then the first entry, thus is because the bit test above wraps at 32 bits instead of 64. scripts/mod/file2alias.c, line 379 reads: if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) That should be: if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG))) Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a 64 bit long, and when that int gets shifted >= 32 times, appearantly the number by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits too low.

2006-07-31[PATCH] vDSO hash-style fixRoland McGrath1-0/+7
The latest toolchains can produce a new ELF section in DSOs and dynamically-linked executables. The new section ".gnu.hash" replaces ".hash", and allows for more efficient runtime symbol lookups by the dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls whether to produce the old ".hash", the new ".gnu.hash", or both. In some new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu to the linker, so that a standard invocation of "gcc -shared" results in producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need to be dealt with the same way as ".hash" sections in all respects; only the dynamic linker cares about their contents. To work with older dynamic linkers (i.e. preexisting releases of glibc), a binary must have the old ".hash" section. The --hash-style=both option produces binaries that a new dynamic linker can use more efficiently, but an old dynamic linker can still handle. The new section runs afoul of the custom linker scripts used to build vDSO images for the kernel. On ia64, the failure mode for this is a boot-time panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed. This patch addresses the problem in two ways. First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash". This produces correct vDSO images with --hash-style=sysv (or old tools), with --hash-style=gnu, or with --hash-style=both. Second, it passes the --hash-style=sysv option when building the vDSO images, so that ".gnu.hash" is not actually produced. This is the most conservative choice for compatibility with any old userland. There is some concern that some ancient glibc builds (though not any known old production system) might choke on --hash-style=both binaries. The optimizations provided by the new style of hash section do not really matter for a DSO with a tiny number of symbols, as the vDSO has. If someone wants to use =gnu or =both for their vDSO builds and worry less about that compatibility, just change the option and the linker script changes will make any choice work fine.

2006-06-24kbuild: support for %.symtypes filesAndreas Gruenbacher3-27/+63
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.

2006-06-24kbuild: add option for stripping modules while installing themTheodore Ts'o1-1/+1
Add option for stripping modules while installing them. This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds.
