When MSR bitmap is updated, evmcs_touch_msr_bitmap function uses current_vmcs per-cpu variable to mark that the msr bitmap was changed. vmx_vcpu_create() modifies the msr bitmap via vmx_disable_intercept_for_msr -> vmx_msr_bitmap_l01_changed which in the end calls this function. The function checks for current_vmcs if it is null but the check is insufficient because current_vmcs is not initialized. Because of this, the code might incorrectly write to the structure pointed by current_vmcs value left by another task. Preemption is not disabled, the current task can be preempted and moved to another CPU while current_vmcs is accessed multiple times from evmcs_touch_msr_bitmap() which leads to crash. The manipulation of MSR bitmaps by callers happens only for vmcs01 so the solution is to use vmx->vmcs01.vmcs instead of current_vmcs.

It assumes dirty tracking is enabled on all memslots to keep a dirty bitmap of pages with changed storage attributes. When enabling migration mode, we currently check that dirty tracking is enabled for all memslots. However, userspace can disable dirty tracking without disabling migration mode. Since migration mode is pointless with dirty tracking disabled, disable migration mode whenever userspace disables dirty tracking on any slot. Also update the documentation to clarify that dirty tracking must be enabled when enabling migration mode, which is already enforced by the code in kvm_s390_vm_start_migration(). Also highlight in the documentation for KVM_S390_GET_CMMA_BITS that it can now fail with -EINVAL when dirty tracking is disabled while migration mode is on. Move all the error codes to a table so this stays readable. To disable migration mode, slots_lock should be held, which is taken in kvm_set_memory_region() and thus held in kvm_arch_prepare_memory_region(). Restructure the prepare code a bit so all the sanity checking is done before disabling migration mode. This ensures migration mode isn't disabled when some sanity check fails.

[PATCH] pinctrl: at91-pio4: fix domain name assignment

by Johan Hovold

Since commit d59f6617eef0 ("genirq: Allow fwnode to carry name information only") an IRQ domain is always given a name during allocation (e.g. used for the debugfs entry). Drop the no longer valid name assignment, which would lead to an attempt to free a string constant when removing the domain on late probe failures (e.g. probe deferral). Fixes: d59f6617eef0 ("genirq: Allow fwnode to carry name information only") Cc: stable(a)vger.kernel.org # 4.13 Signed-off-by: Johan Hovold <johan+linaro(a)kernel.org> --- drivers/pinctrl/pinctrl-at91-pio4.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/pinctrl/pinctrl-at91-pio4.c b/drivers/pinctrl/pinctrl-at91-pio4.c index 39b233f73e13..d699588677a5 100644 --- a/drivers/pinctrl/pinctrl-at91-pio4.c +++ b/drivers/pinctrl/pinctrl-at91-pio4.c @@ -1206,7 +1206,6 @@ static int atmel_pinctrl_probe(struct platform_device *pdev) dev_err(dev, "can't add the irq domain\n"); return -ENODEV; } - atmel_pioctrl->irq_domain->name = "atmel gpio"; for (i = 0; i < atmel_pioctrl->npins; i++) { int irq = irq_create_mapping(atmel_pioctrl->irq_domain, i); -- 2.39.2
