commit 136d9d83 upstream. Commit 37868fe1 ("x86/ldt: Make modify_ldt synchronous") introduced a new struct ldt_struct anchored at mm->context.ldt. convert_ip_to_linear() was changed to reflect this, but indexing into the ldt has to be changed as the pointer is no longer void *. Signed-off-by:

commit 37868fe1 upstream. modify_ldt() has questionable locking and does not synchronize threads. Improve it: redesign the locking and synchronize all threads' LDTs using an IPI on all modifications. This will dramatically slow down modify_ldt in multithreaded programs, but there shouldn't be any multithreaded programs that care about modify_ldt's performance in the first place. This fixes some fallout from the CVE-2015-5157 fixes. Signed-off-by:

commit 3473f265 upstream. The Sourcery CodeBench Lite 2014.05 toolchain (gcc 4.8.3, binutils 2.24.51) has a GCC which implements -fuse-ld, and it doesn't include the gold linker, but it lacks an ld.bfd executable in its installation. This means that passing -fuse-ld=bfd fails with: VDSO arch/arm/vdso/vdso.so.raw collect2: fatal error: cannot find 'ld' Arguably this is a deficiency in the toolchain, but I suspect it's commonly used enough that it's worth accommodating: just use cc-ldoption (to cause a link attempt) instead of cc-option to test whether we can use -fuse-ld. So -fuse-ld=bfd won't be used with this toolchain, but the build will rightly succeed, just as it does for toolchains which don't implement -fuse-ld (and don't use gold as the default linker). Note: this will change the failure mode for a corner case I was trying to handle in d2b30cd4, where the toolchain defaults to the gold linker and the BFD linker is not found in PATH, from: VDSO arch/arm/vdso/vdso.so.raw collect2: fatal error: cannot find 'ld' i.e. the BFD linker is not found, to: OBJCOPY arch/arm/vdso/vdso.so BFD: arch/arm/vdso/vdso.so: Not enough room for program headers, try linking with -N that is, we fail to prevent gold from being used as the linker, and it produces an object that objcopy can't digest.

commit a57e456a upstream. In the recent x2apic cleanup I got two things really wrong: 1) The safety check in __disable_x2apic which allows the function to be called unconditionally is backwards. The check is there to prevent access to the apic MSR in case that the machine has no apic. Though right now it returns if the machine has an apic and therefor the disabling of x2apic is never invoked. 2) x2apic_disable() sets x2apic_mode to 0 after registering the local apic. That's wrong, because register_lapic_address() checks x2apic mode and therefor takes the wrong code path. This results in boot failures on machines with x2apic preenabled by BIOS and can also lead to an fatal MSR access on machines without apic. The solutions are simple: 1) Correct the sanity check for apic availability 2) Clear x2apic_mode _before_ calling register_lapic_address() Fixes: 659006bf 'x86/x2apic: Split enable and setup function' Reported-and-tested-by:

commit 87ffd2b9 upstream. Since commit feb44f1f (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC. This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by disabling Xen support in this configuration. Users needing Xen support in a non-SMP i386 kernel will need to enable CONFIG_X86_UP_APIC. Signed-off-by:

commit 126c69a0 upstream. When injecting a fault into a misbehaving 32bit guest, it seems rather idiotic to also inject a 64bit fault that is only going to corrupt the guest state. This leads to a situation where we perform an illegal exception return at EL2 causing the host to crash instead of killing the guest. Just fix the stupid bug that has been there from day 1.

fnic: Use the local variable instead of I/O flag to acquire io_req_lock in fnic_queuecommand() to avoid deadloack commit db196935 upstream. We added changes in fnic driver patch 1.6.0.16 to acquire io_req_lock in fnic_queuecommand() before issuing I/O so that io completion is serialized. But when releasing the lock we check for the I/O flag and this could be modified if IO abort occurs before I/O completion. In this case we wont release the lock and causes deadlock in some scenerios. Using the local variable to check the IO lock status will resolve the problem. Fixes: 41df7b02Signed-off-by:

commit 06b23f7f upstream. The CAN FD data bittiming constants are provided via netlink only when there are valid CAN FD constants available in priv->data_bittiming_const. Due to the indirection of pointer assignments in the peak_usb driver the priv->data_bittiming_const never becomes NULL - not even for non-FD adapters.

commit 49718f0f upstream. The routines in scsi_rpm.c assume that if a runtime-PM callback is invoked for a SCSI device, it can only mean that the device's driver has asked the block layer to handle the runtime power management (by calling blk_pm_runtime_init(), which among other things sets q->dev). However, this assumption turns out to be wrong for things like the ses driver. Normally ses devices are not allowed to do runtime PM, but userspace can override this setting. If this happens, the kernel gets a NULL pointer dereference when blk_post_runtime_resume() tries to use the uninitialized q->dev pointer. This patch fixes the problem by calling the block layer's runtime-PM routines only if the device's driver really does have a runtime-PM callback routine. Since ses doesn't define any such callbacks, the crash won't occur. This fixes Bugzilla #101371. Signed-off-by:

commit 6d4affea upstream. irq_chip_retrigger_hierarchy() returns -ENOSYS if it was not able to find at least one .irq_retrigger() callback implemented in the IRQ domain hierarchy. That's wrong, because check_irq_resend() expects a 0 return value from the callback in case that the hardware assisted resend was not possible. If the return value is non zero the core code assumes hardware resend success and the software resend is not invoked. This results in lost interrupts on platforms where none of the parent irq chips in the hierarchy implements the retrigger callback. This is observable on TI OMAP, where the hierarchy is: ARM GIC <- OMAP wakeupgen <- TI Crossbar Return 0 instead so the software resend mechanism gets invoked.

commit 63059a27 upstream. The conversion of the wakeupgen irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The wakeupgen irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the wakeupgen irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.

commit 8200fe43 upstream. The TI crossbar irqchip doesn't provides any facility to configure the wakeup sources, but the conversion to hierarchical irqdomains set the irq_set_wake callback to irq_chip_set_wake_parent. The parent chip (OMAP wakeupgen) has no irq_set_wake function either so the call will fail with -ENOSYS. As a result the irq_set_wake() call in the resume path will trigger an 'Unbalanced wake disable' warning. Before the conversion the GIC irqchip was the top level irqchip and correctly flagged with IRQCHIP_SKIP_SET_WAKE. Restore the correct behaviour by removing the irq_set_type callback from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which lets the irq_set_irq_wake() call from the driver succeed.

commit 4fd8f47e upstream. The ARM GIC requires that all interrupts which are not used as a wakeup source have to be masked during suspend. The conversion of the crossbar irqchip to hierarchical irq domains failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND flag and therefor broke the suspend requirement of the GIC. Before the conversion the flags were visible because the GIC was the top level irqchip. After the conversion the crossbar irqchip is the top level irq chip whose flags are evaluated in suspend_device_irq(). As the flag is not set the masking of the non-wakeup irqs is not invoked which breaks suspend. Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the GIC interrupts get masked properly.

commit c7cd0ef6 upstream. The widget power-saving code tries to turn up/down the power of each widget in the I/O paths that are modified at each jack plug/unplug. The recent report revealed that the power activation leaves some widgets unpowered after plugging. This is because snd_hda_activate_path() turns on path->active flag at the end of the function while the path power management is done before that. Then it's regarded as if nothing is active, and the driver turns off the power. The fix is simply to set the flag at the beginning of the function, before trying to power up.
