modpost: use proper kernel style for autogenerated files

2012-05-23T12:58:51Z

If the kernel build process is creating files automatically, the least it can do is create them in a properly formatted manner. Sure, it's a minor issue, but being consistent is nice.

modpost: Stop grab_file() from leaking filedescriptors if fstat() fails

2012-05-23T12:58:49Z

In case the open() call succeeds but the subsequent fstat() call fails, then we'll return without close()'ing the filedescriptor. Signed-off-by: Jesper Juhl Signed-off-by: Rusty Russell

modpost: Fix modpost license checking of vmlinux.o

2012-04-10T03:52:56Z

Commit f02e8a6596b7 ("module: Sort exported symbols") sorts symbols placing each of them in its own elf section. This sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux.o (which is not linked yet) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure. [ This above is a slightly corrected version of the explanation of the problem, copied from commit 62a2635610db ("modpost: Fix modpost's license checking V3"). That commit fixed the problem for module object files, but not for vmlinux.o. This patch fixes modpost for vmlinux.o. ] Signed-off-by: Frank Rowand Signed-off-by: Alessio Igor Bogani Signed-off-by: Linus Torvalds

ARM: 7324/1: modpost: Fix section warnings for ARM for many compilers

2012-02-15T11:04:36Z

It turns out that many compilers don't show section warnings on ARM currently because handling for ARM_CALL relocs are missing from modpost.c. Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and R_ARM_JUMP24 can be handled the same way. Note that at least Debian libc6-dev is missing defines for both R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now we need to define them in modpost.c if not defined.

module,bug: Add TAINT_OOT_MODULE flag for modules not built in-tree

2011-11-06T21:24:42Z

Use of the GPL or a compatible licence doesn't necessarily make the code any good. We already consider staging modules to be suspect, and this should also be true for out-of-tree modules which may receive very little review.

modpost: Fix modpost's license checking V3

2011-07-24T12:36:05Z

The commit f02e8a6 sorts symbols placing each of them in its own elf section. The sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux (already linked) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure.

modpost: Update 64k section support for binutils 2.18.50

2011-05-19T07:25:28Z

Binutils 2.18.50 made a backwards-incompatible change in the way it writes ELF objects with over 65280 sections, to improve conformance with the ELF specification and interoperability with other ELF tools. Specifically, it no longer adds 256 to section indices SHN_LORESERVE and higher to skip over the reserved range SHN_LORESERVE through SHN_HIRESERVE; those values are only considered special in the st_shndx field, and not in other places where section indices are stored.
