Unsupported authentication algorithm (35510)
I'm wondering if some messages that are passed up to user-space via
netlink from the driver might have changed their schema, i.e. adding
new fields in the middle of a structure or moving fields around within
a structure.
Looks more like a crypto problem to me, as this should be the encrypted
challenge in your shared key handshake. IOW, it looks like the frame
isn't getting decrypted by mac80211 for some reason.
Works fine here in hwsim, so likely to be either a driver problem (hw
decrypts frame, but driver doesn't tell us so), something that has been
fixed between then and now, or a compat specific problem.

I'll bump to yesterday's baking, apply your patch, and retry. Maybe it was a spurious issue.
If that doesn't work, I'll try forcing h/w decryption off in the NIC.
Retried with yesterday's baking. No joy. Also reloaded the module with nohwcrypt=1 and same result (except that the value in the auth_alg field changed from 6421 to 44995).
