In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) Reference: https://nvd.nist.gov/vuln/detail/CVE-2019-12904 Patches from: https://github.com/gpg/libgcrypt/commit/1374254c2904ab5b18ba4a890856824a102d4705 https://github.com/gpg/libgcrypt/commit/daedbbb5541cd8ecda1459d3b843ea4d92788762 https://github.com/gpg/libgcrypt/commit/a4c561aab1014c3630bc88faf6f5246fee16b020 (From OE-Core rev: a981d9b753a13e100af1f654fb3384f0bcda0b65) Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> (cherry picked from commit 37e390ff05b6a4509019db358ed496731d80cc51) Signed-off-by: Armin Kuster <akuster808@gmail.com> (cherry picked from commit 4c207cb1ad46c0d2005ab3eae70d78c937e084b5) Signed-off-by: Armin Kuster <akuster808@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
