kbuild: fixdep: Check fstat(2) return value

2016-02-17T21:52:04Z

Coverity has recently added a check that will find when we don't check the return code from fstat(2). Copy/paste the checking logic that print_deps() has with an appropriate re-wording of the perror() message. Signed-off-by: Tom Rini Signed-off-by: Michal Marek

fixdep: constify strrcmp arguments

2015-12-07T11:42:55Z

strrcmp only performs read access to the memory addressed by its arguments so make them const pointers. Signed-off-by: Nicolas Iooss Signed-off-by: Michal Marek

kbuild: fixdep: drop meaningless hash table initialization

2015-08-24T14:36:08Z

The clear_config() is called just once at the beginning of this program, but the global variable hashtab[] is already zero-filled at the start-up. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kbuild: fixdep: optimize code slightly

2015-08-24T14:36:08Z

If the target string matches "CONFIG_", move the pointer p forward. This saves several 7-chars adjustments. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kernel: build bin2c based on config option CONFIG_BUILD_BIN2C

2014-08-08T22:57:32Z

currently bin2c builds only if CONFIG_IKCONFIG=y. But bin2c will now be used by kexec too. So make it compilation dependent on CONFIG_BUILD_BIN2C and this config option can be selected by CONFIG_KEXEC and CONFIG_IKCONFIG.

bin2c: move bin2c in scripts/basic

2014-08-08T22:57:32Z

This patch series does not do kernel signature verification yet. I plan to post another patch series for that. Now distributions are already signing PE/COFF bzImage with PKCS7 signature I plan to parse and verify those signatures. Primary goal of this patchset is to prepare groundwork so that kernel image can be signed and signatures be verified during kexec load. This should help with two things. - It should allow kexec/kdump on secureboot enabled machines. - In general it can help even without secureboot. By being able to verify kernel image signature in kexec, it should help with avoiding module signing restrictions. Matthew Garret showed how to boot into a custom kernel, modify first kernel's memory and then jump back to old kernel and bypass any policy one wants to. This patch (of 15): Kexec wants to use bin2c and it wants to use it really early in the build process. See arch/x86/purgatory/ code in later patches. So move bin2c in scripts/basic so that it can be built very early and be usable by arch/x86/purgatory/ Signed-off-by: Vivek Goyal Cc: Borislav Petkov Cc: Michael Kerrisk Cc: Yinghai Lu Cc: Eric Biederman Cc: H.

kbuild: fixdep: support concatenated dep files

2013-04-05T18:22:58Z

The current use-case for fixdep is: a source file is run through a single processing step, which creates a single dependency file as a side-effect, which fixdep transforms into the file used by the kernel build process. In order to transparently run the C pre-processor on device-tree files, we wish to run both gcc -E and dtc on a source file in a single rule. This generates two dependency files, which must be transformed together into the file used by the kernel build process. This change modifies fixdep so it can process the concatenation of multiple separate input dependency files, and produce a correct unified output. The code changes have the slight benefit of transforming the loop in parse_dep_file() into more of a lexer/tokenizer, with the loop body being more of a parser. Previously, some of this logic was mixed together before the loop. I also added some comments, which I hope are useful. Benchmarking shows that on a cross-compiled ARM tegra_defconfig build, there is less than 0.5 seconds speed decrease with this change, on top of a build time of ~2m24s. This is probably within the noise. Signed-off-by: Stephen Warren Acked-by: Rob Herring

fixdep: fix extraneous dependencies

2011-09-09T09:45:47Z

The introduction of include/linux/kconfig.h created 3 extraneous dependencies: include/config/.h include/config/h.h include/config/foo.h Fix this by excluding kconfig.h from fixdep calculations. Signed-off-by: Peter Foley Signed-off-by: Michal Marek
