# Do not build the annobin plugin with annotation enabled. # This is because if we are bootstrapping a new build environment we can have # a new version of gcc installed, but without a new of annobin installed. # (ie we are building the new version of annobin to go with the new version # of gcc). If the *old* annobin plugin is used whilst building this new # version, the old plugin will complain that version of gcc for which it # was built is different from the version of gcc that is now being used, and # then it will abort. %undefine _annotated_build Name: annobin Summary: Binary annotation plugin for GCC Version: 8.8 Release: 1%{?dist} License: GPLv3+ URL: https://fedoraproject.org/wiki/Toolchain/Watermark # Use "--without tests" to disable the testsuite.

These scripts can determine things ABI clashes in compiled binaries, or the absence of required hardening options. Note - the plugin is enabled in gcc builds via flags provided by the redhat-rpm-macros package, and the analysis tools rely upon the readelf program from the binutils package. #--------------------------------------------------------------------------------- %if %{with tests} %package tests Summary: Test scripts and binaries for checking the behaviour and output of the annobin plugin %description tests Provides a means to test the generation of annotated binaries and the parsing of the resulting files. %endif #--------------------------------------------------------------------------------- %if %{with annocheck} %package annocheck Summary: A tool for checking the security hardening status of binaries BuildRequires: gcc elfutils elfutils-devel elfutils-libelf-devel rpm-devel binutils-devel %description annocheck Installs the annocheck program which uses the notes generated by annobin to check that the specified files were compiled with the correct security hardening options. %endif #--------------------------------------------------------------------------------- %global ANNOBIN_PLUGIN_DIR %(gcc --print-file-name=plugin) # [Stolen from gcc-python-plugin] # GCC will only load plugins that were built against exactly that build of GCC # We thus need to embed the exact GCC version as a requirement within the # metadata. # # Define "gcc_vr", a variable to hold the VERSION-RELEASE string for the gcc # we are being built against. # # Unfortunately, we can't simply run: # rpm -q --qf="%%{version}-%%{release}" # to determine this, as there's no guarantee of a sane rpm database within # the chroots created by our build system # # So we instead query the version from gcc's output. # # gcc.spec has: # Version: %%{gcc_version} # Release: %%{gcc_release}%%{?dist} # ...snip... # echo 'Red Hat %%{version}-%%{gcc_release}' > gcc/DEV-PHASE # # So, given this output: # # $ gcc --version # gcc (GCC) 4.6.1 20110908 (Red Hat 4.6.1-9) # Copyright (C) 2011 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.
