Bug ID: 234073
Summary: ixl: SR-IOV causes "Malicious Driver Detection event"
when not all VFs are in passthrough mode
Product: Base System
Version: 12.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: ix...@riseup.net
SR-IOV config to reproduce:
(the important part is that not all VFs are 'passthrough: true')
/etc/iov/ixl1.conf
---------
PF {
device : "ixl1";
num_vfs : 4;
}
DEFAULT {
passthrough : true;
}
#VF for use by host
VF-0 {
passthrough : false;
}
---------
starting a bhyve VM causes the following errors and the host to loose network
connectivity:
(it only happens if a VM is started)
kernel: ixl1: Malicious Driver Detection event 1 on RX queue 776, pf number 64
(PF-1), (VF-0)
syslogd: last message repeated 352 times
kernel: iavf0: ARQ Critical Error detected
kernel: iavf0: ASQ Critical Error detected
kernel: iavf0: WARNING: Stopping VF!
kernel: iavf0: Unable to send opcode DISABLE_QUEUES to PF, ASQ is not alive
kernel: iavf0: 2<DISABLE_QUEUES> timed out
kernel: iavf0: Unable to send opcode RESET_VF to PF, ASQ is not alive

This problem does not occur when all VFs are in passthrough mode (and the host
does not use ixl1):
example: /etc/iov/ixl1.conf
---------
PF {
device : "ixl1";
num_vfs : 4;
}
DEFAULT {
passthrough : true;
}
