This seems to be breaking a number of hwsim test cases. For example,
ap_ft_sae fails every time when run on its own. When run after some
other FT test cases, it can pass, but that is not really good behavior,
i.e., every single case should work.
I've tested my series on top of 2971da2 and it passes ap_ft_sae for me
also when that test is run alone.
Same goes for the series you send (https://w1.fi/p/ft-rrb/).
Do you use a config file different from example-hostapd.conf?
Something seems to be going wrong with sequence number updating:
FT: Received push
the original message
FT: Received sequence number request
FT: Received sequence number response
The remote AP send
dom = 11 22 b1 de
seq = 62 22 3f bc
ts = 03 00 00 00
when resetting the sequence number.
So seq in range [ seq - 16 - 1; seq ) + (seq, ...) should be accepted
then, see wpa_ft_rrb_rx_seq_resp.
FT: Received push
The original message got restarted automatically.
Its sequence number contains
dom = 11 22 b1 de
seq = 61 22 3f bc
ts = 03 00 00 00
So dom matches and ts cannot fail as well.
The sequence number is in the range configured to be accepted, so this
is fine as well.
When running ap_ft_sae alone on top of the series, I get:
FT: Received push
FT: sequence number - hexdump(len=12): f3 e2 0b 0e c3 e5 aa 47 ac cc 27
00
FT: Possibly invalid sequence number in push from 02:00:00:00:03:00
FT: RRB-OUI type 4 send to 02:00:00:00:03:00

00
FT: S1KH-ID=02:00:00:00:00:00
So I'm puzzled.
