1bcd0b43a16b7a48ec9afce3887c6c841b687abb Author: Roger Pau Monne <roger.pau@xxxxxxxxxx> Date: Mon Feb 18 17:24:28 2019 +0100 vpci: reduce verboseness of BAR write warnings Avoid printing a warning message when writing to a BAR register with memory decoding enabled if the value written is the same as the current one. No functional change. Signed-off-by: Roger Pau Monné <roger.pau@xxxxxxxxxx> Reviewed-by: Jan Beulich <jbeulich@xxxxxxxx> Release-acked-by: Juergen Gross <jgross@xxxxxxxx> commit 24d5282527f4647907b3572820b5335c15cd0356 Author: Razvan Cojocaru <rcojocaru@xxxxxxxxxxxxxxx> Date: Mon Feb 18 13:46:02 2019 +0100 x86/altp2m: fix HVMOP_altp2m_set_domain_state race HVMOP_altp2m_set_domain_state does not domain_pause(), presumably on purpose (as it was originally supposed to cater to a in-guest agent, and a domain pausing itself is not a good idea). This can lead to domain crashes in the vmx_vmexit_handler() code that checks if the guest has the ability to switch EPTP without an exit. That code can __vmread() the host p2m's EPT_POINTER (before HVMOP_altp2m_set_domain_state "for_each_vcpu()" has a chance to run altp2m_vcpu_initialise(), but after d->arch.altp2m_active is set).

However, as written, it has a risk fo deadlock if two vcpus enter the loop at the same time. Luckily, there's already a solution for this: Attempt to call domain's hypercall_deadlock_mutex, and restart the entire hypercall if you fail. Make domain_pause_except_self() attempt to grab this mutex when pausing itself, returning -ERESTART if it fails. Have the callers check for errors and pass the value up. In both cases, the top-level do_hvm_op() should DTRT when -ERESTART is returned. The (necessary) reuse of the hypercall deadlock mutex poses the risk of getting called from a context where the lock was already acquired (e.g. someone may (say) call domctl_lock(), then afterwards call domain_pause_except_self()). However, in the interest of not overcomplicating things, no changes are made here to the mutex. Attempted nesting of this lock isn't a security issue, because all that will happen is that the vcpu will livelock taking continuations.

Print a warning message if dom0_mem is not set when booting in PVH mode. This is a temporary workaround until accounting for internal memory required by Xen (ie: paging structures) is improved.

This however is already checked in set_mmio_p2m_entry, which makes sure that higher order mappings don't overlap with mmio_ro_ranges, thus allowing the creation of high order MMIO mappings safely. Replace the assert to allow 2M/1G entries to be created for MMIO regions and add some extra asserts as a replacement to make sure there's no overlapping with MMIO read-only ranges. Note that 1G MMIO entries will not be created unless mmio_order is changed to allow it.

This requires splitting the current pvh_setup_p2m into two different functions. One that crafts dom0 physmap and sets the paging allocation, and another one that actually populates the p2m with RAM regions. Note that this allows to remove the special casing done for the low 1MB in hwdom_iommu_map.

PVH dom0 builder didn't take this requirement into account, and can call into the p2m/iommu mapping helpers with addresses and orders that are not aligned. Fix this by making sure the orders passed to the physmap population helpers are always aligned to the guest address to be populated.
