I mean if your OS was “smart” as not to send IO to devices that indicate critical failure (e.g. by marking them read-only in the array?), and then thinks all devices have failed critically, wouldn’t this happen in that kind of system as well…

The poor sap was probably trying to get the wifi working :/.

You configure vlans per physical port, so in a properly implemented system your attack won’t be possible. When the packet comes to the switch the vlan tag is added to it according to the configuration for the port it was received from.

Or are you talking about mac-vlans?

Depends on you hw. That seems rather poor implementation… I believe my TP switch might handle that, because it rejects traffic to its management interface from mac X from vlan 20 because it sees the same mac in vlan 10… (only vlan 20 is allowed for management)

And did mentioning these things just make the message disappear on US-based lemmy-instances?

I don’t believe it did.

That’s pretty low bar for calling something a “quirk”. The whole ML family, so OCaml, SML, Haskell, F# and perhaps a the new distant relative Rust call it also it None.

And it’s not even the same thing: null means pointer to nothing, while None means no value.

How is None a quirk?
