Users seeing STATUS_CANCELLED from PacketReceivePacket() #1903
Description
That error has been reported in Wireshark bug 16329 and bug 16355.
It looks as if the most likely reason for that would be that NPF_Pause() is called before pcap_dispatch()/pcap_loop() without NPF_Restart() also having been called after NPF_Pause() but before the libpcap routine.
According to Pausing a Driver Stack; might that be occurring due to adding (or removing?) a binding? The second bug involves disconnecting from the Wi-Fi network, which might tweak bindings if, for example, a disconnected adapter doesn't have the Internet protocol stack bound to it but a connected adapter does.
Is this covered by the comment
/* TODO: Allow the read to continue if the filter module is
* detached (NPF_StartUsingOpenInstance above returned false)
* but we have packet data in the buffer that can still be
* delivered. */
in NPF_Read()?
And should there be OpenPausing and OpenPaused states, so that the instance isn't marked as "closing" or "closed" if it's just being paused or finished being paused?

That sounds reasonable. I'll take a closer look at making these changes after the next release (this week, I hope), since I want this to be a solid bugfix release without new features.

I came here from Wireshark's bug 16329, referenced above.
I figured adding more details here instead of there would be better, sorry if this isn't the correct place. I'll move my report there if this isn't appropriate.
It's basically the same error reported there:
But, in my case I'm getting this very consistently when sending Windows 10 into hibernation, while Wireshark is running a capture, on a WIFI interface. This messages appears when I restart from the hibernation and switch back to Wireshark.

This should be resolved in Npcap 0.9988, released today.

This is still occurring with Npcap 0.9990.

coming from wireshark bug 16329, I assume it is the same bug (did not catch all details). I saw it today with Wireshark 3.2.4 and Npcap 0.9991
I was capturing from wifi generated by a test device, doing a netcat transfer test.

As of the most recent commit, the driver's read routine returns
STATUS_CANCELLEDonly ifNPF_StartUsingOpenInstance()returns FALSE, so, unless there's another way to getSTATUS_CANCELLEDfromNtReadFile()or to get error 995 (ERROR_OPERATION_ABORTED) from packet.dll, that's probably what's happening.
