Trying to run a modified version of the wifi transceiver from this repo:
https://github.com/bastibl/gr-ieee802-11
Swapped out the USRP source for Osmocom (HackRF), and the USRP sink for a
null sink. When I try to run it, I get this error:
Traceback (most recent call last):

RuntimeError: gr::tuntap_pdu::make: tun_alloc failed (are you running as

I am most assuredly *not* running as root, and I'm unsure what
"gr::tuntap_pdu::make" or "tun_alloc" are. There was one similar email
chain (https://marc.info/?l=gnuradio-discuss&m=141563926501407&w=2) from a
few years ago, but the solution he found doesn't seem to work; changing
TUNTAP PDU doesn't fix the problem.
Anyone have a clue as to why these tuntap pdu things are acting up?
