Alex Williamson d0f63acc2f igb: Fix null pointer dereference ... The max_vfs= option has always been self limiting to the number of VFs supported by the device. fa44f2f1 added SR-IOV configuration via sysfs, but in the process broke this self correction factor. The failing path is: igb_probe igb_sw_init if (max_vfs > 7) { adapter->vfs_allocated_count = 7; ... igb_probe_vfs igb_enable_sriov(, max_vfs) if (num_vfs > 7) { err = -EPERM; ... This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out when igb_probe finally calls igb_reset. It seems like a really bad idea, and somewhat pointless, to set vfs_allocated_count separate from vf_data, but limiting max_vfs is enough to avoid the null pointer.
