2019-03-13toolchain: set the ssp gcc option in kconfigYann E. MORIN
Currently, we repeat all the SSP level selection deep down to the toolchain wrapper itself, where we eventually translate it to the actual SSP option to use. This is a bit redundant. Additionally, we will want to check that the toolchain actually supports that option (for those toolchain where it was backported). So, move the translation into kconfig, and add the qstrip'ed value to the additional flags passed to the wrapper. Add it before user-supplied opitons, to keep the previous behaviour (and allow anyone crazy-enough to override it with BR2_TARGET_OPTIMIZATION). Signed-off-by: "Yann E.

2019-02-04toolchain: add variadic MI thunk support flagMax Filippov
GCC uses thunk functions to adjust the 'this' pointer when calling C++ member functions in classes derived with multiple inheritance. Generation of thunk functions requires support from the compiler back end. In the absence of that support target-independent code in the C++ front end is used to generate thunk functions, but it does not support vararg functions. Support for this feature is currently missing in or1k and xtensa toolchains. Add hidden option BR2_TOOLCHAIN_SUPPORTS_VARIADIC_MI_THUNK that indicates presence of this feature in the toolchain. Add dependency to packages that require this feature to be built.

atomic ops Initially we had a port only for ARCv2 cores but then with a simple change ARCompact cores got supported as well. So we generalize from BR2_archs to BR2_arcle as we haven't tried to get glibc working on big-endian ARCs yet. Also we never bothered to check avaialbility of atomic instructions in the core but in case of Glibc for ARC this is really a must, so we add this check here. Note in case of uClibc we may have system w/o HW atomics but: 1. Only single-core systems are allowed 2. Atomic instructions are emulated via arc_usr_cmpxchg syscall Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Cc: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
2018-10-21toolchain: move glibc nsswitch.conf handling to a post-target hookPeter Korsgaard
nsswitch.conf is processed both by the toolchain, nss-mdns and nss-myhostname without any guaranteed ordering in between. The toolchain package ensures that nsswitch.conf is available, and the two nss-* packages tweaks the content, so the toolchain processing should run before the nss-* ones. Toolchain is a dependency of all the packages, so ensure this is done by moving the toolchain handling to a post-target-install hook. Also move the variable to toolchain/toolchain/toolchain.mk where the virtual toolchain package is defined for clarity. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

2018-10-20toolchain/toolchain-wrapper: add BR2_RELRO_Matt Weber
The RELRO/PIE flags are currently passed via CFLAGS/LDFLAGS and this patch proposes moving them to the toolchain wrapper. (1) The flags should _always_ be passed, without leaving the possibility for any package to ignore them. I.e, when BR2_RELRO_FULL=y is used in a build, all executables should be built PIE. Passing those options through the wrapper ensures they are used during the build of all packages. (2) Some options are incompatible with -fPIE. For example, when building object files for a shared libraries, -fPIC is used, and -fPIE shouldn't be used in combination with -fPIE. Similarly, -r or -static are directly incompatible as they are different link time behaviors then the intent of PIE. Passing those options through the wrapper allows to add some "smart" logic to only pass -fPIE/-pie when relevant. (3) Some toolchain, kernel and bootloader packages may want to explicitly disable PIE in a build where the rest of the userspace has intentionally enabled it. The wrapper provides an option to key on the -fno-pie/-no-pie and bypass the appending of RELRO flags. The current Kernel and U-boot source trees include this option. https://github.com/torvalds/linux/commit/8438ee76b004ef66d125ade64c91fc128047d244 https://github.com/u-boot/u-boot/commit/6ace36e19a8cfdd16ce7c02625edf36864897bf5 If using PIE with a older Kernel and/or U-boot version, a backport of these changes might be required. However this patchset also uses the __KERNEL__ and __UBOOT__ defines as a way to disable PIE. NOTE: The current implementation via CFLAGS/LDFLAGS has caused some build time failures as the conditional logic doesn't yet exist in Buildroot: https://bugs.busybox.net/show_bug.cgi?id=11206 https://bugs.busybox.net/show_bug.cgi?id=11321 Good summary of the most common build failures related to enabling pie: https://wiki.ubuntu.com/SecurityTeam/PIE [Peter: minor cleanups] Signed-off-by: Matthew Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

2018-08-21toolchain: improve musl check to support static toolchainsThomas Petazzoni
The check_musl function currently builds a program and verifies if the program interpreter starts with /lib/ld-musl. While this works fine for dynamically linked programs, this obviously doesn't work for a purely static musl toolchain such as [1]. There is no easy way to identify a toolchain as using the musl C library. For glibc, dynamic linking is always supported, so we look at the dynamic linker name. For uClibc, there is a distinctive uClibc_config.h header file. There is no such distinctive feature in musl. We end up resorting to looking for the string MUSL_LOCPATH, which is used by musl locale_map.c source file. This string has been present in musl since 2014. It certainly isn't a very stable or convincing solution to identify the C library as being musl, but it's the best we could find. Note that we are sure there is a libc.a file, because the check_unusable_toolchain function checks that there is a such a file.
