gpp_maybe Security update for the linux kernel
slessp4-kernel-20180512-13618

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were 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" - CVE-2018-1000199: An address corruption flaw was discovered while modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to potentially escalate privileges on a the system. (bsc#1089895) - CVE-2018-10675: The do_get_mempolicy function in mm/mempolicy.c allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls (bnc#1091755). - CVE-2017-5715: The retpoline mitigation for Spectre v2 has been enabled also for 32bit x86. - CVE-2017-5753: Spectre v1 mitigations have been improved by the versions merged from the upstream kernel. The following non-security bugs were fixed: - Avoid quadratic search when freeing delegations (bsc#1084760). - cifs: fix crash due to race in hmac(md5) handling (bsc#1091671). - hid: roccat: prevent an out of bounds read in kovaplus_profile_activated() (bsc#1087092). - mmc: jz4740: Fix race condition in IRQ mask update (bsc#1090888). - powerpc/64: Disable gmb() on powerpc - 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#1075088, bsc#1091815). - 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: Improve RFI L1-D cache flush fallback (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/64s: Move cpu_show_meltdown() (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/64s: Patch barrier_nospec in modules (bsc#1068032, bsc#1080157). - powerpc/64s: Wire up cpu_show_spectre_v1() (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/64s: Wire up cpu_show_spectre_v2() (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/64: Use barrier_nospec in syscall entry (bsc#1068032, bsc#1080157). - powerpc: Add security feature flags for Spectre/Meltdown (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc: Move default security feature flags (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc: Move local setup.h declarations to arch includes (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/pseries: Add new H_GET_CPU_CHARACTERISTICS flags (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/pseries: Fix clearing of security feature flags (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/pseries: Restore default security feature flags on setup (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/pseries: Set or clear security feature flags (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/pseries: Use the security flags in pseries_setup_rfi_flush() (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/rfi-flush: Always enable fallback flush on pseries (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/rfi-flush: Call setup_rfi_flush() after LPM migration (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/rfi-flush: Differentiate enabled and patched flush types (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc/rfi-flush: Make it possible to call setup_rfi_flush() again (bsc#1068032, bsc#1075088, bsc#1091815). - powerpc: Use barrier_nospec in copy_from_user() (bsc#1068032, bsc#1080157). - series.conf: fix the header It was corrupted back in 2015. - tracing: Create seq_buf layer in trace_seq (bsc#1091815). - Update config files. Enable retpolines for i386 build. - usb: Accept bulk endpoints with 1024-byte maxpacket (bsc#1090888). - usb: hub: fix SS hub-descriptor handling (bsc#1092372). - x86/bugs: correctly force-disable IBRS on !SKL systems (bsc#1092497). - x86/kaiser: export symbol kaiser_set_shadow_pgd() (bsc#1090630) - x86/xen: disable IBRS around CPU stopper function invocation - xen-netfront: fix req_prod check to avoid RX hang when index wraps (bsc#1046610). - xfs: fix buffer use after free on IO error (bsc#1052943). - xfs: prevent recursion in xfs_buf_iorequest (bsc#1052943).
