This requires using recursive locking for the ioreq server lock, as the offending invocation of sh_remove_all_mappings() is down the call stack from hvm_set_ioreq_server_state(). (While not strictly needed to be done in all other instances too, convert all of them for consistency.) At once improve the usefulness of the shadow error message: Log all values involved in triggering it as well as the GFN (to aid understanding which guest page it is that there is a problem with - in cases like the one here the GFN is invariant across invocations, while the MFN obviously can [and will] vary).

Similarly the tsc_timestamp, part of struct vcpu_time_info, is calculated from stime_local_stamp using gtime_to_gtsc. However gtime_to_gtsc can return 0, if time < vtsc_offset, which can actually happen when gtime_to_gtsc is called passing stime_local_stamp (the caller function is __update_vcpu_system_time). In that case the pvclock protocol doesn't work properly and the guest is unable to calculate the system time correctly. As a consequence when the guest tries to set a timer event (for example calling the VCPUOP_set_singleshot_timer hypercall), the event will be in the past causing Linux to hang. The purpose of the pvclock protocol is to allow the guest to calculate the system_time in nanosec correctly. The guest calculates as follow: from_vtsc_scale(rdtsc - vcpu_time_info.tsc_timestamp) + vcpu_time_info.system_time Given that with vtsc=1: rdtsc = to_vtsc_scale(NOW() - vtsc_offset) vcpu_time_info.tsc_timestamp = to_vtsc_scale(vcpu_time_info.system_time - vtsc_offset) The expression evaluates to NOW(), which is what we want. However when stime_local_stamp < vtsc_offset, vcpu_time_info.tsc_timestamp is actually 0. As a consequence the calculated overall system_time is not correct. This patch fixes the issue by letting gtime_to_gtsc return a negative integer in the form of a wrapped around unsigned integer, thus when the guest subtracts vcpu_time_info.tsc_timestamp from rdtsc will calculate the right value.

This was due to the PV driver with the call to register_oldmem_pfn_is_ram() API was not including the kernel header file that is used to communicate support of the API in the kernel. Fix the issue by including the required header file.

This causes misbehavior in at least the MSI-X and VGA code, which want to see all such requests for internal tracking/caching purposes. But note that this does not apply to buffered I/O requests. This in turn means that the condition in hvm_process_io_intercept() of when to crash the domain was wrong: Since X86EMUL_UNHANDLEABLE can validly be returned by the individual device handlers, we mustn't blindly crash the domain if such occurs on other than the initial iteration. Instead we need to distinguish hvm_copy_*_guest_phys() failures from device specific ones, and then the former need to always be fatal to the domain (i.e. also on the first iteration), since otherwise we again would end up forwarding a request to qemu which the internal handler didn't get to see. The adjustment should be okay even for stdvga's MMIO handling: - if it is not caching then the accept function would have failed so we won't get into hvm_process_io_intercept(), - if it issued the buffered ioreq then we only get to the p->count reduction if hvm_send_ioreq() actually encountered an error (in which we don't care about the request getting split up). Also commit 4faffc41d ("x86/hvm: limit reps to avoid the need to handle retry") went too far in removing code from hvm_process_io_intercept(): When there were successfully handled iterations, the function should continue to return success with a clipped repeat count.

We need to identify this case so we can correctly apply the check for whether to save/restore FCS/FDS. By poisoning FIP in the saved state we can check if the hardware writes to this field. The poison value is both: a) non-canonical; and b) random with a vanishingly small probability of matching a value written by the hardware (1 / (2^63) = 10^-19). The poison value is fixed and thus knowable by a guest (or guest userspace). This could allow the guest to cause Xen to incorrectly detect that the field has not been written. But: a) this requires the FIP register to be a full 64 bits internally which is not the case for all current AMD and Intel CPUs; and b) this only allows the guest (or a guest userspace process) to corrupt its own state (i.e., it cannot affect the state of another guest or another user space process). This results in smaller code with fewer branches and is more understandable. Signed-off-by: David Vrabel <david.vrabel@xxxxxxxxxx> Intel confirmed that 64-bit {F,}XRSTOR sign-extend FIP from bit 47.

Add a per-domain field to indicate which of these options a guest needs. The options are: 8, 4 or 0. Where 0 indicates that the hypervisor should automatically guess the FIP width by checking the value of FIP/FDP when saving the state (this is the existing behaviour). The FIP width is initially automatic but is set explicitly in the following cases: - 32-bit PV guest: 4 - Newer CPUs that do not save FCS/FDS: 8 The x87_fip_width field is placed into an existing 1 byte hole in struct arch_domain.
