[PATCH v3 6.6] iommu: Handle race with default domain setup

by Robin Murphy

[ Upstream commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 ] It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes. [ Backport: The above is true for mainline, but here we still have arch_setup_dma_ops() to worry about, which is not replayed if the default domain happens to be allocated *between* that call and subsequently reaching iommu_device_use_default_domain(), so we need an additional earlier check to cover that case. Also we're now back before the nominal commit 98ac73f99bc4 so we need to tweak the logic to depend on IOMMU_DMA as well, to avoid falsely deferring on architectures not using default domains. This then serves us back as far as f188056352bc, where this specific form of the problem first arises. ] Reported-by: Charan Teja Kalla <quic_charante(a)quicinc.com> Fixes: 98ac73f99bc4 ("iommu: Require a default_domain for all iommu drivers") Fixes: f188056352bc ("iommu: Avoid locking/unlocking for iommu_probe_device()") Link: https://lore.kernel.org/r/e88b94c9b575034a2c98a48b3d383654cbda7902.17407532… Signed-off-by: Robin Murphy <robin.murphy(a)arm.com> --- Resending as a new version with a new Message-Id so as not to confuse the tools... 6.12.y should simply have a straight cherry-pick of the mainline commit - 98ac73f99bc4 was in 6.7 so I'm not sure why autosel hasn't picked that already?

The issue has been observed with Raspberry Pi devices at least since 4.14 (see [1], bug report for their downstream kernel), as well as with Nvidia devices [2] in 2020, where disabling interrupts was the vendor-suggested workaround (together with the claim that phylib changes in 4.9 made the interrupt handling in lan78xx incompatible). Iperf reports well over 900Mbits/sec per direction with client in --dualtest mode, so there does not seem to be a significant impact on throughput (lan88xx device connected via switch to the peer).
