builddeb: remove debian/files before build

2015-10-16T18:42:28Z

Commit 3716001bcb7f ("deb-pkg: add source package") added the ability to create a debian changelog file. This exposed that previously the builddeb script hasn't cleared debian/files between builds. As debian/files keeps accumulating entries, the changes file will end up growing indefinelty. With outdated entries in debian/files, builddeb script will exit with failure. This regression impacts those who use "make deb-pkg" target to build kernel into a .deb package and never use "make mrproper" or other means to clean kernel tree from generated directories. To fix the regression, remove debian/files before starting build and in the generated clean rule.

MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old

2015-09-25T15:31:46Z

The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file since that allows the target X.509 certificate to be specified by subjectKeyId rather than by issuer + serialNumber. However, older versions of the OpenSSL crypto library (such as may be found in CentOS 5.11) don't support CMS. Assume everything prior to OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case. Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so give an error from the sign-file script if the caller requests anything other than SHA1. The compiler gives the following error with an OpenSSL crypto library that's too old: HOSTCC scripts/sign-file scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory #include Reported-by: Vinson Lee Signed-off-by: David Howells Acked-by: David Woodhouse

KEYS: Remove unnecessary header #inclusions from extract-cert.c

Remove headers #included unnecessarily from extract-cert.c lest they cause compilation of the tool to fail against an older OpenSSL library. Signed-off-by: David Howells Acked-by: David Woodhouse

modsign: Fix GPL/OpenSSL licence incompatibility

2015-09-15T20:54:21Z

The GPL does not permit us to link against the OpenSSL library. Use LGPL for sign-file and extract-file instead. [ The whole "openssl isn't compatible with gpl" is really just fear-mongering, but there's no reason not to make modsign LGPL, so nobody cares. - Linus ] Reported-by: Julian Andres Klode Signed-off-by: David Woodhouse Signed-off-by: David Howells Reviewed-by: Julian Andres Klode Signed-off-by: Linus Torvalds

MODSIGN: fix a compilation warning in extract-cert

2015-09-11T22:21:34Z

Fix the following warning when compiling extract-cert: scripts/extract-cert.c: In function `write_cert': scripts/extract-cert.c:89:2: warning: format not a string literal and no format arguments [-Wformat-security] ERR(!i2d_X509_bio(wb, x509), cert_dst); ^ whereby the ERR() macro is taking cert_dst as the format string. "%s" should be used as the format string as the path could contain special characters.

checkpatch: add constant comparison on left side test

2015-09-10T20:29:01Z

"CONST variable" checks like: if (NULL != foo) and while (0 < bar(...)) where a constant (or what appears to be a constant like an upper case identifier) is on the left of a comparison are generally preferred to be written using the constant on the right side like: if (foo != NULL) and while (bar(...) > 0) Add a test for this. Add a --fix option too, but only do it when the code is immediately surrounded by parentheses to avoid misfixing things like "(0 < bar() + constant)" Signed-off-by: Joe Perches Cc: Nicolas Morey Chaisemartin Cc: Viresh Kumar Cc: Dan Carpenter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

checkpatch: add __pmem to $Sparse annotations

2015-09-10T20:29:01Z

commit 61031952f4c8 ("arch, x86: pmem api for ensuring durability of persistent memory updates") added a new __pmem annotation for sparse verification. Add __pmem to the $Sparse variable so checkpatch can appropriately ignore uses of this attribute too.
