arm64: atomics: patch in lse instructions when supported by the CPU On CPUs which support the LSE atomic instructions introduced in ARMv8.1, it makes sense to use them in preference to ll/sc sequences. This patch introduces runtime patching of atomic_t and atomic64_t routines so that the call-site for the out-of-line ll/sc sequences is patched with an LSE atomic instruction when we detect that the CPU supports it. If binutils is not recent enough to assemble the LSE instructions, then the ll/sc sequences are inlined as though CONFIG_ARM64_LSE_ATOMICS=n.

arm64: errata: Add -mpc-relative-literal-loads to build flags commit 67dfa1751ce71e629aad7c438e1678ad41054677 upstream. GCC6 (and Linaro's 2015.12 snapshot of GCC5) has a new default that uses adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419 is enabled, modules built with this toolchain fail to load: module libahci: unsupported RELA relocation: 275 This patch fixes the problem by passing '-mpc-relative-literal-loads' to the compiler.

arm64: errata: add module build workaround for erratum #843419 Cortex-A53 processors <= r0p4 are affected by erratum #843419 which can lead to a memory access using an incorrect address in certain sequences headed by an ADRP instruction. There is a linker fix to generate veneers for ADRP instructions, but this doesn't work for kernel modules which are built as unlinked ELF objects. This patch adds a new config option for the erratum which, when enabled, builds kernel modules with the mcmodel=large flag. This uses absolute addressing for all kernel symbols, thereby removing the use of ADRP as a PC-relative form of addressing. The ADRP relocs are removed from the module loader so that we fail to load any potentially affected modules.

arm64: errata: use KBUILD_CFLAGS_MODULE for erratum #843419 Commit df057cc7b4fa ("arm64: errata: add module build workaround for erratum #843419") sets CFLAGS_MODULE to ensure that the large memory model is used by the compiler when building kernel modules.

arm64: Enable TEXT_OFFSET fuzzing The arm64 Image header contains a text_offset field which bootloaders are supposed to read to determine the offset (from a 2MB aligned "start of memory" per booting.txt) at which to load the kernel. The offset is not well respected by bootloaders at present, and due to the lack of variation there is little incentive to support it. This is unfortunate for the sake of future kernels where we may wish to vary the text offset (even zeroing it). This patch adds options to arm64 to enable fuzz-testing of text_offset. CONFIG_ARM64_RANDOMIZE_TEXT_OFFSET forces the text offset to a random 16-byte aligned value value in the range [0..2MB) upon a build of the kernel. It is recommended that distribution kernels enable randomization to test bootloaders such that any compliance issues can be fixed early.

arm64: align randomized TEXT_OFFSET on 4 kB boundary When booting via UEFI, the kernel Image is loaded at a 4 kB boundary and the embedded EFI stub is executed in place. The EFI stub relocates the Image to reside TEXT_OFFSET bytes above a 2 MB boundary, and jumps into the kernel proper. In AArch64, PC relative symbol references are emitted using adrp/add or adrp/ldr pairs, where the offset into a 4 kB page is resolved using a separate :lo12: relocation. This implicitly assumes that the code will always be executed at the same relative offset with respect to a 4 kB boundary, or the references will point to the wrong address. This means we should link the kernel at a 4 kB aligned base address in order to remain compatible with the base address the UEFI loader uses when doing the initial load of Image. So update the code that generates TEXT_OFFSET to choose a multiple of 4 kB. At the same time, update the code so it chooses from the interval [0..2MB) as the author originally intended.

arm64: add KASAN support This patch adds arch specific code for kernel address sanitizer (see Documentation/kasan.txt). 1/8 of kernel addresses reserved for shadow memory. There was no big enough hole for this, so virtual addresses for shadow were stolen from vmalloc area. At early boot stage the whole shadow region populated with just one physical page (kasan_zero_page). Later, this page reused as readonly zero shadow for some memory that KASan currently don't track (vmalloc). After mapping the physical memory, pages for shadow memory are allocated and mapped. Functions like memset/memmove/memcpy do a lot of memory accesses. If bad pointer passed to one of these function it is important to catch this. Compiler's instrumentation cannot do this since these functions are written in assembly. KASan replaces memory functions with manually instrumented variants. Original functions declared as weak symbols so strong definitions in mm/kasan/kasan.c could replace them. Original functions have aliases with '__' prefix in name, so we could call non-instrumented variant if needed. Some files built without kasan instrumentation (e.g. mm/slub.c). Original mem* function replaced (via #define) with prefixed variants to disable memory access checks for such files.

The EFI libstub directory is referenced by the kernel build system via a obj subdirectory rule in: drivers/firmware/efi/Makefile Unfortunately, arm64 also references the EFI libstub via: libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/ If we're unlucky, the kernel build system can enter libstub via two simultaneous threads resulting in build failures such as: fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2 Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed make: *** [drivers/firmware/efi/libstub] Error 2 make: *** Waiting for unfinished jobs....

dts, arm/arm64: Remove dtbs build rules in sub-makes Add dtb files to build targets and let kbuild handle them. Thus, special dtbs rules can be removed. This eases Makefiles and the implementation of the support of vendor dtb subdirectories. Signed-off-by: Robert Richter <rrichter@cavium.com>

dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst Move dtbs install rules to Makefile.dtbinst. This change is needed to implement support for dts vendor subdirs.

arm64: Add dtb files to archclean rule As dts files have been reorganised under vendor subdirs, dtb files cannot be removed with "make distclean" now. Thus, this patch moves dtb files under archclean rule and removes unnecessary entries.

dts, arm64: Add dtbs_install make target This adds the dtbs_install make target to arm64. The target has been introduced already to arch/arm with the following commit: f4d4ffc03efc kbuild: dtbs_install: new make target Implementation for arm64 is the same as for arm. With 'dtbs_install' all config enabled dtb files are installed to either the INSTALL_DTBS_PATH directory or the default location: $INSTALL_PATH/dtbs/$KERNELRELEASE Signed-off-by: Robert Richter <rrichter@cavium.com>
