That is, the alternative() in UNTRAIN_RET # will patch in the CALL to srso_alias_untrain_ret() directly. # # However, even if commit e7c25c441e9e ("x86/cpu: Cleanup the untrain # mess") meant well in trying to clean up the situation, due to micro- # architectural reasons, the untraining routine srso_alias_untrain_ret() # must be the target of a CALL instruction and not of a JMP instruction as # it is done now. # # Reshuffle the alternative macros to accomplish that. # # Fixes: e7c25c441e9e ("x86/cpu: Cleanup the untrain mess") # Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> # Reviewed-by: Ingo Molnar <mingo@kernel.org> # Cc: stable@kernel.org # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 4535e1a4174c4111d92c5a9a21e542d232e0fcaa # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:14248:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:14252:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:14254:warning: override: reassigning to symbol UML_NET_SLIP .config:14259:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/x86/um/user-offsets.c:17:6: warning: no previous prototype for ‘foo’ [-Wmissing-prototypes] 17 \| void foo(void) \| ^~~ In file included from /kisskb/src/arch/um/kernel/asm-offsets.c:1: /kisskb/src/arch/x86/um/shared/sysdep/kernel-offsets.h:9:6: error: no previous prototype for ‘foo’ [-Werror=missing-prototypes] 9 \| void foo(void) \| ^~~ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:117: arch/um/kernel/asm-offsets.s] Error 1 make[2]: * [/kisskb/src/Makefile:1197: prepare0] Error 2 make[1]: * [/kisskb/src/Makefile:240: __sub-make] Error 2 make: * [Makefile:240: __sub-make] Error 2 Command 'make -s -j 40 ARCH=um O=/kisskb/build/linus_allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allmodconfig_um-x86_64-gcc12 # Build took: 0:00:18.167788
