* MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too oldDavid Howells2015-09-251-17/+77
| | | | | | | | | | | | | | | | | | | | | | | | | 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 <openssl/cms.h> Reported-by: Vinson Lee <vlee@twopensource.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | The GPL does not permit us to link against the OpenSSL library. Use LGPL for sign-file and extract-file instead.

Since newer gcc (>= 4.6) knows about -fstack-usage, we might as well take the information straight from the horse's mouth. This patch introduces scripts/stackusage, which is a simple wrapper for running make with KCFLAGS set to -fstack-usage. Example use is scripts/stackusage -o out.su -j8 lib/ The script understands "-o foo" for writing to 'foo' and -h for a trivial help text; anything else is passed to make. Afterwards, we find all newly created .su files, massage them a little, sort by stack use and write the result to a single output file. Note that the function names printed by (at least) gcc 4.7 are sometimes useless. For example, the first three lines of out.su generated above are ./lib/decompress_bunzip2.c:155 get_next_block 448 static ./lib/decompress_unlzma.c:537 unlzma 336 static ./lib/vsprintf.c:616 8 304 static That function '8' is really the static symbol_string(), but it has been subject to 'interprocedural scalar replacement of aggregates', so its name in the object file is 'symbol_string.isra.8'. gcc 5.0 doesn't have this problem; it uses the full name as seen in the object file. [1] Since gcc encodes that by 48 83 c4 80 add $0xffffffffffffff80,%rsp and not 48 81 ec 80 00 00 00 sub $0x80,%rsp since -128 fits in an imm8.

| * | builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and ↵Andrey Skvortsov2015-05-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_MODULE_SIG_ALL are set If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg, tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO is NOT set. In that case deb-package contains signed modules. But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with debug information. To do that, debug information from all modules is copied into separate files by objcopy. And loadable kernel modules are stripped afterwards. Stripping removes previously (during modules_install) added signatures from loadable kernel modules. Therefore final deb-package contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL. This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set to solve this problem.

COMMANDs and PARAMs are treated slightly different by the underlying parser. While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled characters") introduced a warning for unsupported characters around PARAMs, it does not cover situations where a COMMAND has additional characters before it. This change makes Kconfig emit a warning if superfluous characters are found before COMMANDs. As the 'help' statement sometimes is written as '---help---', the '-' character would now also be regarded as unhandled and generate a warning. To avoid that, '-' is added to the list of allowed characters, and the token '---help---' is included in the zconf.gperf file.

We also cannot detect clang after including the arch Makefile, because powerpc wants to know about clang. Solve this by using an deferred variable.
