[Bisected] Connection failures when using wl driver (Broadcom) since rev. f2a6ad01

[Evgenii Shatokhin]

Hi,

After update of wpa_supplicant from v.2.4 to v2.6, the system can no 
longer connect to WiFi networks. The problem persists from the current 
version of wpa_supplicant from git (rev. aaa9c60b) as well.

NetworkManager shows "Configuring interface" for the chosen SSID and 
after some time just tells that the connection failed ("disconnected")

The problem only happens when I use the proprietary driver (wl) from 
Broadcom for the WiFi adapter. Everything seems to be OK with the 
opensource driver though.

The log of wpa_supplicant is attached.

Version 2.4 worked OK with both drivers.

git bisect pointed to the following commit as the first "bad" one:

----------------
commit f2a6ad01a943103c658de5721c2d7f7e91ee7fa4
Author: Jouni Malinen <j at w1.fi>
Date:   Sun Nov 29 18:59:27 2015 +0200

     TLS client: Add support for server certificate probing
----------------

OS: ROSA Linux x86_64
Kernel: 4.8.14
WiFi adapter: Broadcom BCM4313 (PCI IDs: 14e4:4727)
broadcom-wl: version 6.30.223.271

More info about the hardware, just in case: 
https://linux-hardware.org/index.php?probe=53e076bc6c.

Any ideas what could go wrong here and how to deal with it?

I have the hardware where the problem reproduces reliably, so I can test 
patches if needed.

Regards,
Evgenii
