Description SMASH SMASH 2024-02-19 09:38:46 UTC

An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled.

Comment 1 Carlos López 2024-02-19 09:40:22 UTC

I'm not too familiar with SR/IOV but this seems almost a duplicate of bsc#1220062. Affectedness is the same I'd say:
 - SUSE:SLE-15-SP5:Update/qemu
 - SUSE:ALP:Source:Standard:1.0/qemu
 - openSUSE:Factory/qemu

Comment 2 Dario Faggioli 2024-03-19 09:13:03 UTC

Ok, I think it landed upstream as 91bb64a8d2014fda33a81fcf0fce37340f0d3b0c ("hw/nvme: Use pcie_sriov_num_vfs()").

It has a "Fixes: 11871f53ef8e" tag, and 11871f53ef8e is present in QEMU >= 7.1.0 (so, for us, >= 15-SP5, as comment 1 correctly states)
