Lu Baolu 6e02a277f1 iommu/vt-d: Fix incorrect pci_for_each_dma_alias() for non-PCI devices ... Previously, the domain_context_clear() function incorrectly called pci_for_each_dma_alias() to set up context entries for non-PCI devices. This could lead to kernel hangs or other unexpected behavior. Add a check to only call pci_for_each_dma_alias() for PCI devices. For non-PCI devices, domain_context_clear_one() is called directly. Reported-by: Todd Brandt <todd.e.brandt@intel.com> Closes: https://bugzilla.kernel.org/show_bug.cgi?id=219363 Closes: https://bugzilla.kernel.org/show_bug.cgi?id=219349 Fixes: 9a16ab9d64 ("iommu/vt-d: Make context clearing consistent with context mapping") Cc: stable@vger.kernel.org Signed-off-by: Lu Baolu <baolu.lu@linux.intel.com> Link: https://lore.kernel.org/r/20241014013744.102197-2-baolu.lu@linux.intel.com Signed-off-by: Joerg Roedel <jroedel@suse.de>		History 2024-10-15 10:17:54 +02:00
