kbuild: Use Elfnn_Half as replacement for Elfnn_Section

2007-10-12T19:13:50Z

The Elfnn_Section is not available on all platforms, noteworthy are cygwin. Use the safe replacement _Half. Signed-off-by: Sam Ravnborg

kbuild: make better section mismatch reports on i386 and mips

2007-07-16T19:48:49Z

On i386 and MIPS, warn_sec_mismatch() sometimes fails to show usefull symbol name. This is because empty 'refsym' due to 0 r_addend value. This patch is to adjust r_addend value, consulting with apply_relocate() routine in kernel code. Signed-off-by: Atsushi Nemoto Signed-off-by: Sam Ravnborg

Revert "kbuild: make better section mismatch reports on i386, arm and mips"

2007-05-22T01:41:17Z

This reverts commit f892b7d480eec809a5dfbd6e65742b3f3155e50e, which totally broke the build on x86 with CONFIG_RELOCATABLE (which, as far as I can tell, is the only case where it should even matter!) due to a SIGSEGV in modpost. Cc: Sam Ravnborg Cc: Atsushi Nemoto Signed-off-by: Linus Torvalds

kbuild: make better section mismatch reports on i386, arm and mips

On i386, ARM and MIPS, warn_sec_mismatch() sometimes fails to show usefull symbol name. This is because empty 'refsym' due to 0 r_addend value. This patch is to adjust r_addend value, consulting with apply_relocate() routine in kernel code. Without this patch: MODPOST vmlinux WARNING: init/built-in.o - Section mismatch: reference to .init.text: from .text between 'rest_init' (at offset 0xf4) and 'try_name' WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap' WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap' With this patch: MODPOST vmlinux WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap' WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap' Now modpost can detect "kernel_init" name (and whitelist it) and show "set_up_list3s" name.

kbuild: distinguish between errors and warnings in modpost

2007-05-02T18:58:08Z

Some of modpost's warnings are fatal, and some are not. Adopt the compiler distinction between errors and warnings by calling merror() for fatal diagnostics and warn() for non-fatal ones. merror() was used as replacemtn for error() to avoid clash with glibc Signed-off-by: Matthew Wilcox Signed-off-by: Sam Ravnborg

kbuild: warn when a moduled uses a symbol marked UNUSED

2006-07-01T09:44:23Z

We now have infrastructure in place to mark an EXPORTed symbol as unused. So the natural next step is to warn during buildtime when a module uses a symbol marked UNUSED. Signed-off-by: Sam Ravnborg

kbuild: check license compatibility when building modules

2006-06-09T19:53:55Z

Modules that uses GPL symbols can no longer be build with kbuild, the build will fail during the modpost step. When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol then warn during modpost so author are actually notified. The actual license compatibility check is shared with the kernel to make sure it is in sync. Patch originally from: Andreas Gruenbacher and Ram Pai Signed-off-by: Sam Ravnborg

kbuild: export-type enhancement to modpost.c

2006-06-09T18:33:10Z

This patch provides the ability to identify the export-type of each exported symbols in Module.symvers. NOTE: It updates the Module.symvers file with the additional information as shown below. 0x0f8b92af platform_device_add_resources vmlinux EXPORT_SYMBOL_GPL 0xcf7efb2a ethtool_op_set_tx_csum vmlinux EXPORT_SYMBOL Signed-off-by: Andreas Gruenbacher Signed-off-by: Ram Pai Signed-off-by: Avantika Mathur Signed-off-by: Valdis Kletnieks Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

[PATCH] kbuild: fix modpost segfault for 64bit mipsel kernel

2006-05-21T19:59:21Z

Here is an updated r_info layout fix. Please apply "check SHT_REL sections" patch before this. 64bit mips has different r_info layout. This patch fixes modpost segfault for 64bit little endian mips kernel. Signed-off-by: Atsushi Nemoto Cc: Sam Ravnborg Cc: Ralf Baechle Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] kbuild: check SHT_REL sections

2006-05-21T19:59:21Z

I found that modpost can not detect section mismatch on mips and i386. On mips64, the modpost (with r_info layout fix) can detect it. The current modpst only checks SHT_RELA section but I suppose SHT_REL section should be checked also. This patch does not contain r_info layout fix. I'll post an updated r_info layout fix on next mail. Check SHT_REL sections as like as SHT_RELA sections to detect section mismatch.
