gpp_maybe Security update for the linux kernel
SUSE-SLE-SERVER-12-SP2-2018-956

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bug was fixed: - CVE-2018-3639: Information leaks using "Memory Disambiguation" feature in modern CPUs were mitigated, aka "Spectre Variant 4" (bnc#1087082). A new boot commandline option was introduced, "spec_store_bypass_disable", which can have following values: - auto: Kernel detects whether your CPU model contains an implementation of Speculative Store Bypass and picks the most appropriate mitigation. - on: disable Speculative Store Bypass - off: enable Speculative Store Bypass - prctl: Control Speculative Store Bypass per thread via prctl. Speculative Store Bypass is enabled for a process by default. The state of the control is inherited on fork. - seccomp: Same as "prctl" above, but all seccomp threads will disable SSB unless they explicitly opt out. The default is "seccomp", meaning programs need explicit opt-in into the mitigation. Status can be queried via the /sys/devices/system/cpu/vulnerabilities/spec_store_bypass file, containing: - "Vulnerable" - "Mitigation: Speculative Store Bypass disabled" - "Mitigation: Speculative Store Bypass disabled via prctl" - "Mitigation: Speculative Store Bypass disabled via prctl and seccomp" The following related and non-security bugs were fixed: - cpuid: Fix cpuid.edx.7.0 propagation to guest - ext4: Fix hole length detection in ext4_ind_map_blocks() (bsc#1090953). - ibmvnic: Clean actual number of RX or TX pools (bsc#1092289). - kvm: Introduce nopvspin kernel parameter (bsc#1056427). - kvm: Fix nopvspin static branch init usage (bsc#1056427). - powerpc/64: Use barrier_nospec in syscall entry (bsc#1068032, bsc#1080157). - powerpc/64s: Add barrier_nospec (bsc#1068032, bsc#1080157). - powerpc/64s: Add support for ori barrier_nospec patching (bsc#1068032, bsc#1080157). - powerpc/64s: Enable barrier_nospec based on firmware settings (bsc#1068032, bsc#1080157). - powerpc/64s: Enhance the information in cpu_show_meltdown() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/64s: Enhance the information in cpu_show_spectre_v1() (bsc#1068032). - powerpc/64s: Fix section mismatch warnings from setup_rfi_flush() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/64s: Move cpu_show_meltdown() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/64s: Patch barrier_nospec in modules (bsc#1068032, bsc#1080157). - powerpc/64s: Wire up cpu_show_spectre_v1() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/64s: Wire up cpu_show_spectre_v2() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/powernv: Set or clear security feature flags (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/powernv: Use the security flags in pnv_setup_rfi_flush() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/pseries: Add new H_GET_CPU_CHARACTERISTICS flags (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/pseries: Fix clearing of security feature flags (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/pseries: Restore default security feature flags on setup (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/pseries: Set or clear security feature flags (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/pseries: Use the security flags in pseries_setup_rfi_flush() (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/rfi-flush: Always enable fallback flush on pseries (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/rfi-flush: Differentiate enabled and patched flush types (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc/rfi-flush: Make it possible to call setup_rfi_flush() again (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc: Add security feature flags for Spectre/Meltdown (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc: Move default security feature flags (bsc#1068032, bsc#1075087, bsc#1091041). - powerpc: Use barrier_nospec in copy_from_user() (bsc#1068032, bsc#1080157).
