 # rpi-toolchain
-A gcc cross toolchain for all Raspberry Pi models with multiarch support
+
+A gcc cross toolchain for all Raspberry Pi models with multiarch support.
+
+Linaro toolchains are built using a tool called ABE. This is similar to
+crosstool-ng. After building it produces a manifest which can be used to
+reproduce the build.
+
+This toolchain is built by taking the Linaro release manifest and modifying
+the compiler configuration to produce armv6 compatible binaries which can
+run on all models of Raspberry Pi.
+
+The changes required for this are very small. In the manifest, only the
+variables `gcc_stage1_flags` and `gcc_stage2_flags` are modified.
+
+The flags:
+
+    --with-fpu=vfpv3-d16 --with-mode=thumb --with-tune=cortex-a9 --with-arch=armv7-a
+
+are replaced by:
+
+    --with-fpu=vfp --with-arch=armv6

+
+    Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
+
+    The LD_HWCAP_MASK environment variable may alter the selection of
+    function variants for some architectures.  For AT_SECURE process it
+    means that if an outdated routine has a bug that would otherwise not
+    affect newer platforms by default, LD_HWCAP_MASK will allow that bug
+    to be exploited.
+
+    To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
+    binaries.
+
+    	[BZ #21209]
+    	* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
+    	AT_SECURE processes.
+    	* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.
