| * scripts: modpost: Remove numeric suffix pattern matchingRasmus Villemoes2014-07-271-39/+10
| | | | | | | | | | | | | | | | | | | | For several years, the pattern "foo$" has effectively been treated as equivalent to "foo" due to a bug in the (misnamed) helper number_prefix(). This hasn't been observed to cause any problems, so remove the broken $ functionality and change all foo$ patterns to foo.

* | kernel: build bin2c based on config option CONFIG_BUILD_BIN2CVivek Goyal2014-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/basicVivek Goyal2014-08-095-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <vgoyal@redhat.com> Cc: Borislav Petkov <bp@suse.de> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: H.

For instance: "unsigned short" and "signed short" are found by checkpatch as a specific type, but none of the or "int short" or "int signed short" variants are found. Add another table for the "kernel style misordered" variants. Add this misordered table to the findable types. Warn when the misordered style is used. This improves the "Missing a blank line after declarations" test as it depends on the correct parsing of the $Declare variable which looks for "$Type $Ident;" (ie: declarations like "int foo;").

These messages generally increase kernel size without much added value. Emit a warning on these types of messages. This test looks for any inserted message function, then looks at the previous line for an "if (!foo)" or "if (foo == NULL)" test and then looks at the preceding statement for an allocation function like "foo = kmalloc()" ie: this code matches: foo = kmalloc(); if (foo == NULL) { printk("Out of memory\n"); return -ENOMEM; } This test is very crude and incomplete. This test can miss quite a lot of of OOM messages that do not have this specific form. ie: this code does not match: foo = kmalloc(); if (!foo) { rtn = -ENOMEM; printk("Out of memory!\n"); goto out; } This test could also be a false positive when the logging message itself does not specify anything about memory, but I did not find any false positives in my limited testing. spatch could be a better solution but correctness seems non-trivial for that tool too.

I'll provide a version of this for stable trees if it's deemed that we need to backport it. The second patch causes the component helper to ignore duplicate matches when adding components - this is something that was originally needed for imx-drm, but since that has now been updated, we no longer need to skip over a component which has already been matched. The final patch starts the process of updating the component helper API to achieve two goals: to allow the API to be more efficient when deferred probing occurs, and to allow for future improvements to the component helper without having a major impact on the users. This represents groundwork for some other changes; once this has been merged, I will then send two further pull requests (one for the staging tree, and one for the DRM tree) to update the drivers to the new API. This will result in these three commits being shared with those trees.
