In fact both # conditions need to be true. Otherwise the enablement of LBR in the # IA32_XSS MSR fails and subsequently the machine crashes on the next # XRSTORS operation because IA32_XSS is not initialized. # # Cache the XSTATE support bit during init and make the related # functions use this cached information and the LBR CPU feature bit to # cure this. # # - Cure a long standing bug in KASLR # # KASLR uses the full address space between PAGE_OFFSET and vaddr_end # to randomize the starting points of the direct map, vmalloc and # vmemmap regions. It thereby limits the size of the direct map by # using the installed memory size plus an extra configurable margin for # hot-plug memory. This limitation is done to gain more randomization # space because otherwise only the holes between the direct map, # vmalloc, vmemmap and vaddr_end would be usable for randomizing. # # The limited direct map size is not exposed to the rest of the kernel, # so the memory hot-plug and resource management related code paths # still operate under the assumption that the available address space # can be determined with MAX_PHYSMEM_BITS. # # request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1 # downwards. That means the first allocation happens past the end of # the direct map and if unlucky this address is in the vmalloc space, # which causes high_memory to become greater than VMALLOC_START and # consequently causes iounmap() to fail for valid ioremap addresses. # # Cure this by exposing the end of the direct map via PHYSMEM_END and # use that for the memory hot-plug and resource management related # places instead of relying on MAX_PHYSMEM_BITS. In the KASLR case # PHYSMEM_END maps to a variable which is initialized by the KASLR # initialization and otherwise it is based on MAX_PHYSMEM_BITS as # before. # # - Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of # an initialized variabled on the stack to the VMM. The variable is # only required as output value, so it does not have to exposed to the # VMM in the first place. # # - Prevent an array overrun in the resource control code on systems with # Sub-NUMA Clustering enabled because the code failed to adjust the # index by the number of SNC nodes per L3 cache. # # * tag 'x86-urgent-2024-09-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/resctrl: Fix arch_mbm_* array overrun on SNC # x86/tdx: Fix data leak in mmio_read() # x86/kaslr: Expose and use the end of the physical memory address space # x86/fpu: Avoid writing LBR bit to IA32_XSS unless supported # x86/apic: Make x2apic_disable() work correctly # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 c9f016e72b5cc7d4d68fac51f8e72c8c7a69c06e # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- g5_defconfig # < make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/linus_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_g5_defconfig_powerpc-gcc5 # Build took: 0:01:09.407232
