This avoids disabling # L1TF on machines which utilize the full physical address space. # # - Fix the GDT mapping for EFI calls on 32bit PTI # # - Fix the MCE nospec implementation to prevent #GP # # Fixes and robustness: # # - Use the proper operand order for LSL in the VDSO # # - Prevent NMI uaccess race against CR3 switching # # - Add a lockdep check to verify that text_mutex is held in # text_poke() functions # # - Repair the fallout of giving native_restore_fl() a prototype # # - Prevent kernel memory dumps based on usermode RIP # # - Wipe KASAN shadow stack before rewinding the stack to prevent false # positives # # - Move the AMS GOTO enforcement to the actual build stage to allow # user API header extraction without a compiler # # - Fix a section mismatch introduced by the on demand VDSO mapping # change # # Miscellaneous: # # - Trivial typo, GCC quirk removal and CC_SET/OUT() cleanups" # # * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/pti: Fix section mismatch warning/error # x86/vdso: Fix lsl operand order # x86/mce: Fix set_mce_nospec() to avoid #GP fault # x86/efi: Load fixmap GDT in efi_call_phys_epilog() # x86/nmi: Fix NMI uaccess race against CR3 switching # x86: Allow generating user-space headers without a compiler # x86/dumpstack: Don't dump kernel memory based on usermode RIP # x86/asm: Use CC_SET()/CC_OUT() in __gen_sigismember() # x86/alternatives: Lockdep-enforce text_mutex in text_poke*() # x86/entry/64: Wipe KASAN stack shadow before rewind_stack_do_exit() # x86/irqflags: Mark native_restore_fl extern inline # x86/build: Remove jump label quirk for GCC older than 4.5.2 # x86/Kconfig: Fix trivial typo # x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+ # x86/spectre: Add missing family 6 check to microcode check # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 899ba79553cf1699bdcd262950b48501b0285529 # < make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n | make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- In file included from /kisskb/src/include/linux/bitmap.h:9, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/arch/x86/include/asm/paravirt.h:17, from /kisskb/src/arch/x86/include/asm/irqflags.h:68, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/rcupdate.h:39, from /kisskb/src/include/linux/rculist.h:11, from /kisskb/src/include/linux/pid.h:5, from /kisskb/src/include/linux/sched.h:14, from /kisskb/src/kernel/debug/kdb/kdb_support.c:15: In function 'strncpy', inlined from 'kallsyms_symbol_next' at /kisskb/src/kernel/debug/kdb/kdb_support.c:239:4: /kisskb/src/include/linux/string.h:246:9: warning: '__builtin_strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] return __builtin_strncpy(p, q, size);
