Default is either seccomp or prctl (if seccomp is # disabled in Kconfig). prctl allows mitigation opt-in, seccomp # enables the migitation for sandboxed processes. # # - Rework the code to handle the conditional STIBP/IBPB control and # remove the now unused ptrace_may_access_sched() optimization # attempt # # - Disable STIBP automatically when SMT is disabled # # - Optimize the switch_to() logic to avoid MSR writes and invocations # of __switch_to_xtra(). # # - Make the asynchronous speculation TIF updates synchronous to # prevent stale mitigation state. # # As a general cleanup this also makes retpoline directly depend on # compiler support and removes the 'minimal retpoline' option which just # pretended to provide some form of security while providing none" # # * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits) # x86/speculation: Provide IBPB always command line options # x86/speculation: Add seccomp Spectre v2 user space protection mode # x86/speculation: Enable prctl mode for spectre_v2_user # x86/speculation: Add prctl() control for indirect branch speculation # x86/speculation: Prepare arch_smt_update() for PRCTL mode # x86/speculation: Prevent stale SPEC_CTRL msr content # x86/speculation: Split out TIF update # ptrace: Remove unused ptrace_may_access_sched() and MODE_IBRS # x86/speculation: Prepare for conditional IBPB in switch_mm() # x86/speculation: Avoid __switch_to_xtra() calls # x86/process: Consolidate and simplify switch_to_xtra() code # x86/speculation: Prepare for per task indirect branch speculation control # x86/speculation: Add command line control for indirect branch speculation # x86/speculation: Unify conditional spectre v2 print functions # x86/speculataion: Mark command line parser data __initdata # x86/speculation: Mark string arrays const correctly # x86/speculation: Reorder the spec_v2 code # x86/l1tf: Show actual SMT state # x86/speculation: Rework SMT state change # sched/smt: Expose sched_smt_present static key # ... # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 4b78317679c4f3782a3cff0ddb269c1fcfde7621 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/linus_pasemi_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- pasemi_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/linus_pasemi_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:152:32: warning: 'levelspread[<Ub0a0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:100:6: note: 'levelspread[<Ub0a0>]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1433:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/dma-buf/reservation.c: In function 'reservation_object_add_shared_fence': /kisskb/src/drivers/dma-buf/reservation.c:208:2: warning: 'k' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/dma-buf/reservation.c:161:17: note: 'k' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2076:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_pasemi_defconfig_powerpc # Build took: 0:01:09.028582
