2021-08-20dm ima: update dm target attributes for ima measurementsTushar Sugandhi
Certain DM targets ('integrity', 'multipath', 'verity') need to update the way their attributes are recorded in the ima log, so that the attestation servers can interpret the data correctly and decide if the devices meet the attestation requirements. For instance, the "mode=%c" attribute in the 'integrity' target is measured twice, the 'verity' target is missing the attribute "root_hash_sig_key_desc=%s", and the 'multipath' target needs to index the attributes properly. Update 'integrity' target to remove the duplicate measurement of the attribute "mode=%c". Add "root_hash_sig_key_desc=%s" attribute for the 'verity' target. Index various attributes in 'multipath' target. Also, add "nr_priority_groups=%u" attribute to 'multipath' target to record the number of priority groups.

2021-08-20dm ima: add a warning in dm_init if duplicate ima events are not measuredTushar Sugandhi
The end-users of DM devices/targets may remove and re-create the same device multiple times. IMA does not measure such duplicate events if the configuration CONFIG_IMA_DISABLE_HTABLE is set to 'n'. To avoid confusion, the end-users need some indication on the client if that configuration option is disabled. Add a one-time warning during dm_init() if CONFIG_IMA_DISABLE_HTABLE is set to 'n', to notify the end-users that duplicate events will not be measured in the ima log. Also cleanup some whitespace in dm_init(). Signed-off-by: Tushar Sugandhi <tusharsu@linux.microsoft.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2021-08-20dm ima: prefix ima event name related to device mapper with dm_Tushar Sugandhi
The event names for the DM events recorded in the ima log do not contain any information to indicate the events are part of the DM devices/targets. Prefix the event names for DM events with "dm_" to indicate that they are part of device-mapper.

2021-08-20dm ima: add version info to dm related events in ima logTushar Sugandhi
The DM events present in the ima log contain various attributes in the key=value format. The attributes' names/values may change in future, and new attributes may also get added. The attestation server needs some versioning to determine which attributes are supported and are expected in the ima log. Add version information to the DM events present in the ima log to help attestation servers to correctly process the attributes across different versions.

The active/inactive table hashes measured in the ima log do not contain the information about hash algorithm. This information is useful for the attestation servers to recreate the hashes and compare them with the ones present in the ima log to verify the table contents.

1) New index member of struct rxe_queue was introduced but not zeroed so the initial value of index may be random. 2) The current index is not masked off to index_mask. In this case producer_addr() and consumer_addr() will get an invalid address by the random index and then accessing the invalid address triggers the following panic: "BUG: unable to handle page fault for address: ffff9ae2c07a1414" Fix the issue by using kzalloc() to zero out index member.

The registers are latched on every C10 entry or exit and on every s0ix.y entry/exit. Accessing these registers is useful for debugging any low power related activities. Thus, add debugfs entry to access low power mode status registers.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter).

2021-08-20iommu/io-pgtable: Abstract iommu_iotlb_gather accessRobin Murphy
Previously io-pgtable merely passed the iommu_iotlb_gather pointer through to helpers, but now it has grown its own direct dereference. This turns out to break the build for !IOMMU_API configs where the structure only has a dummy definition. It will probably also crash drivers who don't use the gather mechanism and simply pass in NULL. Wrap this dereference in a suitable helper which can both be stubbed out for !IOMMU_API and encapsulate a NULL check otherwise.

2021-08-20irqchip/gic-v3: Fix priority comparison when non-secure priorities are usedChen-Yu Tsai
When non-secure priorities are used, compared to the raw priority set, the value read back from RPR is also right-shifted by one and the highest bit set. Add a macro to do the modifications to the raw priority when doing the comparison against the RPR value. This corrects the pseudo-NMI behavior when non-secure priorities in the GIC are used. Tested on 5.10 with the "IPI as pseudo-NMI" series [1] applied on MT8195.
