That avoids the Spectre-v1 speculation barriers. # # Right now only x86-64 takes advantage of this, and not all architectures # will be able to do it. It requires a guard region between the user and # kernel address spaces (so that you can't overflow from one to the # other), and an easy way to generate a guaranteed-to-fault address for # invalid user pointers. # # Also note that this currently assumes that there is no difference # between user read and write accesses. If extended to architectures like # powerpc, we'll also need to separate out the user read-vs-write cases. # # * address-masking: # x86: make the masked_user_access_begin() macro use its argument only once # x86: do the user address masking outside the user access area # x86: support user address masking instead of non-speculative conditional # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 de5cb0dcb74c294ec527eddfe5094acfdb21ff21 # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/fork.c: In function '__do_sys_clone3': /kisskb/src/kernel/fork.c:3078:2: error: #warning clone3() entry point is missing, please fix [-Werror=cpp] 3078 | #warning clone3() entry point is missing, please fix | ^~~~~~~ cc1: all warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:244: kernel/fork.o] Error 1 make[4]: *** Waiting for unfinished jobs.... make[3]: *** [/kisskb/src/scripts/Makefile.build:485: kernel] Error 2 make[3]: *** Waiting for unfinished jobs.... {standard input}: Assembler messages: {standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive {standard input}:1397: Error: pcrel too far sh4-linux-gcc: internal compiler error: Segmentation fault signal terminated program cc1 Please submit a full bug report, with preprocessed source (by using -freport-bug).
