| | * | | x86/fpu: Disable MPX when eagerfpu is offyu-cheng yu2018-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a5fe93a549c54838063d2952dd9643b0b18aa67f upstream. This issue is a fallout from the command-line parsing move. When "eagerfpu=off" is given as a command-line input, the kernel should disable MPX support. The decision for turning off MPX was made in fpu__init_system_ctx_switch(), which is after the selection of the XSAVE format. This patch fixes it by getting that decision done earlier in fpu__init_system_xstate().

Those are stupid and code should use static_cpu_has_safe() or boot_cpu_has() instead. Kill the least used and unused ones. The remaining ones need more careful inspection before a conversion can happen. On the TODO.

The function fpu__init_system() is executed before parse_early_param(). This causes wrong FPU configuration. This patch fixes this issue by parsing boot_command_line in the beginning of fpu__init_system().

| | * | | MIPS: prctl: Disallow FRE without FR with PR_SET_FP_MODE requestsMaciej W. Rozycki2018-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 28e4213dd331e944e7fca1954a946829162ed9d4 upstream. Having PR_FP_MODE_FRE (i.e. Config5.FRE) set without PR_FP_MODE_FR (i.e. Status.FR) is not supported as the lone purpose of Config5.FRE is to emulate Status.FR=0 handling on FPU hardware that has Status.FR=1 hardwired[1][2]. Also we do not handle this case elsewhere, and assume throughout our code that TIF_HYBRID_FPREGS and TIF_32BIT_FPREGS cannot be set both at once for a task, leading to inconsistent behaviour if this does happen. Return unsuccessfully then from prctl(2) PR_SET_FP_MODE calls requesting PR_FP_MODE_FRE to be set with PR_FP_MODE_FR clear. This corresponds to modes allowed by `mips_set_personality_fp'.

Clear the PCR (Processor Compatibility Register) on boot to ensure we are not running in a compatibility mode. We've seen this cause problems when a crash (and kdump) occurs while running compat mode guests. The kdump kernel then runs with the PCR set and causes problems. The symptom in the kdump kernel (also seen in petitboot after fast-reboot) is early userspace programs taking sigills on newer instructions (seen in libc).

For LSE atomics that read and write a register operand, we need to ensure that these operands are annotated as "early clobber" if the register is written before all of the input operands have been consumed. Failure to do so can result in the compiler allocating the same register to both operands, leading to splats such as: Unable to handle kernel paging request at virtual address 11111122222221 [...] x1 : 1111111122222222 x0 : 1111111122222221 Process swapper/0 (pid: 1, stack limit = 0x000000008209f908) Call trace: test_atomic64+0x1360/0x155c where x0 has been allocated as both the value to be stored and also the atomic_t pointer. This patch adds the missing clobbers.

The return from the ftrace_stub, _mcount, ftrace_caller and return_to_handler functions is done with "br %r14" and "br %r1". These are indirect branches as well and need to use execute trampolines for CONFIG_EXPOLINE=y. The ftrace_caller function is a special case as it returns to the start of a function and may only use %r0 and %r1. For a pre z10 machine the standard execute trampoline uses a LARL + EX to do this, but this requires *two* registers in the range %r1..%r15. To get around this the 'br %r1' located in the lowcore is used, then the EX instruction does not need an address register. But the lowcore trick may only be used for pre z14 machines, with noexec=on the mapping for the first page may not contain instructions. The solution for that is an ALTERNATIVE in the expoline THUNK generated by 'GEN_BR_THUNK %r1' to switch to EXRL, this relies on the fact that a machine that supports noexec=on has EXRL as well.

Normal kernel doesn't have this bug. Kernel parameter 'noapic' is used to disable IO-APIC in system for testing or special purpose. Here the root cause is that in kdump kernel LAPIC is disabled since commit: 522e664644 ("x86/apic: Disable I/O APIC before shutdown of the local APIC") In this case we need set up through-local-APIC on boot CPU in setup_local_APIC(). In normal kernel the legacy irq mode is enabled by the BIOS. If it is virtual wire mode, the local-APIC has been enabled and set as through-local-APIC. Though we fixed the regression introduced by commit 522e664644, to further improve robustness set up the through-local-APIC mode explicitly, do not rely on the default boot IRQ mode.

Called from DT IRQ parser, irq_create_fwspec_mapping() calls irq_domain_alloc_irqs() with a pointer to irq_fwspec structure as @arg. But x86-specific DT IRQ allocation code casts @arg to of_phandle_args structure pointer and crashes trying to read the IRQ parameters. The function was not converted when the mapping descriptor was changed to irq_fwspec in the generic irqdomain code.

Unlike Big RM, KVM doesn't support emulating exceptions in PM, i.e. PM exceptions are always injected via the VMCS. Because we will never do VMRESUME due to emulation_required, the exception is never realized and we'll keep emulating the faulting instruction over and over until we receive a signal. Exit to userspace iff there is a pending exception, i.e. don't exit simply on a requested event. The purpose of this check and exit is to aid in debugging a guest that is in all likelihood already doomed. Invalid guest state in PM is extremely limited in normal operation, e.g. it generally only occurs for a few instructions early in BIOS, and any exception at this time is all but guaranteed to be fatal. Non-vectored interrupts, e.g. INIT, SIPI and SMI, can be cleanly handled/emulated, while checking for vectored interrupts, e.g. INTR and NMI, without hitting false positives would add a fair amount of complexity for almost no benefit (getting hit by lightning seems more likely than encountering this specific scenario). Add a WARN_ON_ONCE to vmx_queue_exception() if we try to inject an exception via the VMCS and emulation_required is true.

But the generic ioremap() code does not check whether the PMD/PUD entries are already populated with a non-leaf entry, so that any page-table pages these entries point to will be lost. Further, on x86-32 with SHARED_KERNEL_PMD=0, this causes a BUG_ON() in vmalloc_sync_one() when PMD entries are synced from swapper_pg_dir to the current page-table. This happens because the PMD entry from swapper_pg_dir was promoted to a huge-page entry while the current PGD still contains the non-leaf entry. Because both entries are present and point to a different page, the BUG_ON() triggers. This was actually triggered with pti-x32 enabled in a KVM virtual machine by the graphics driver. A real and better fix for that would be to improve the page-table handling in the generic ioremap() code. But that is out-of-scope for this patch-set and left for later work. Reported-by: David H.

With a radix host we have the possibility that the backing memory page size can be 2MB or 1GB. In these cases, if the guest switches to HPT mode, KVM will not initialize the VRMA and the guest will fail to run. In fact it is not necessary that the VRMA page size is the same as the backing memory page size; any VRMA page size less than or equal to the backing memory page size is acceptable.

Otherwise noirq resume for devices has already happened. And then dev_pm_disarm_wake_irq() has already disabled the dedicated wake irqs when the interrupt triggers and the wake irq is never handled. For devices that are already in PM runtime suspended state when we enter suspend this means that a possible wake irq will never trigger. And this can lead into a situation where a device has a pending padconf wake irq, and the device will stay unresponsive to any further wake irqs. This issue can be easily reproduced by setting serial console log level to zero, letting the serial console idle, and suspend the system from an ssh terminal. Then try to wake up the system by typing to the serial console. Note that this affects only omap3 PRM interrupt as that's currently the only omap variant that does anything in omap_pm_wake(). In general, for the wake irqs to work, the interrupt must have either IRQF_NO_SUSPEND or IRQF_EARLY_RESUME set for it to trigger before dev_pm_disarm_wake_irq() disables the wake irqs.

The problems of interest include: * Nodes known to powerpc to be memoryless at boot, but to have CPUs in them are allowed to be 'possible' and 'online'. Memory allocations for those nodes are taken from another node that does have memory until and if memory is hot-added to the node. * Nodes which have no resources assigned at boot, but which may still be referenced subsequently by affinity or associativity attributes, are kept in the list of 'possible' nodes for powerpc. Hot-add of memory or CPUs to the system can reference these nodes and bring them online instead of redirecting the references to one of the set of nodes known to have memory at boot. Note that this software operates under the context of CPU hotplug. We are not doing memory hotplug in this code, but rather updating the kernel's CPU topology (i.e. arch_update_cpu_topology / numa_update_cpu_topology). We are initializing a node that may be used by CPUs or memory before it can be referenced as invalid by a CPU hotplug operation. CPU hotplug operations are protected by a range of APIs including cpu_maps_update_begin/cpu_maps_update_done, cpus_read/write_lock / cpus_read/write_unlock, device locks, and more. Memory hotplug operations, including try_online_node, are protected by mem_hotplug_begin/mem_hotplug_done, device locks, and more. In the case of CPUs being hot-added to a previously memoryless node, the try_online_node operation occurs wholly within the CPU locks with no overlap. Using HMC hot-add/hot-remove operations, we have been able to add and remove CPUs to any possible node without failures. HMC operations involve a degree self-serialization, though.
