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.
What kind of changes are there in wpa_supplicant on top of the actually
released versions? This logs show following line:
properties_get_or_set: Set(PreassocMacAddr)
No additional patches, I just built the code from the git repo, master
branch. The configuration is attached, if that matters.
while PreassocMacAddr does not seem to exist in hostap.git version at
all.. Please also note that this configures random MAC address use which
is failing in the debug log apparently due to driver not supporting it.
Version 2.4 worked OK with both drivers.
Using random MAC addresses?
I made no changes in the connection settings.
I just checked out tag hostap_2_4 in git repo, copied the attached
config file to .config, then - cd wpa_supplicant && make. Then as follows:
systemctl stop wpa_supplicant
cp wpa_supplicant wpa_cli wpa_passphrase /usr/sbin/
systemctl start wpa_supplicant
iw dev wlan0 scan # to force the scan for the NM to see the connections
After that, I selected the appropriate SSID in NM and the connection was
established.
Checkout 'master' again, do the same steps => connection failure.
git bisect pointed to the following commit as the first "bad" one:
commit f2a6ad01a943103c658de5721c2d7f7e91ee7fa4
Author: Jouni Malinen <j@xxxxx>
Date: Sun Nov 29 18:59:27 2015 +0200
TLS client: Add support for server certificate probing
I would find it very unlikely for this commit to have anything to do
with this issue.. Are you even building in the code this touches (i.e.,
CONFIG_TLS=internal)? In any case, that functionality is not used before
the association is established.
dbus: org.freedesktop.DBus.Properties.Set (/fi/w1/wpa_supplicant1/Interfaces/1) [ssv]
properties_get_or_set: Set(PreassocMacAddr)
preassoc_mac_addr=1
This functionality does not exist in upstream version over D-Bus
interface..
Could it be that NetworkManager messes with these things somehow?
Because, I used the original, unpached code for testing.
By the way, if that matters, the following service file is used for
wpa_supplicant in that system:
-----------------
[Unit]
Description=WPA Supplicant daemon
Before=network.target
After=syslog.target
[Service]
Type=dbus
BusName=fi.w1.wpa_supplicant1
EnvironmentFile=-/etc/sysconfig/wpa_supplicant
ExecStart=/usr/sbin/wpa_supplicant -c /etc/wpa_supplicant.conf
$INTERFACES $DRIVERS $OTHER_ARGS
[Install]
WantedBy=multi-user.target
-----------------
/etc/sysconfig/wpa_supplicant:
-----------------
INTERFACES=""
DRIVERS=""
OTHER_ARGS="-u -f /var/log/wpa_supplicant.log -P
/var/run/wpa_supplicant.pid"
-----------------
/etc/wpa_supplicant.conf - the same as
wpa_supplicant/wpa_supplicant.conf in the git repo but with network={}
blocks commented out.
No mention of PreassocMacAddr or similar stiff here which makes me think
it is set by something else.
wlan0: Starting radio work 'scan'@0x1fb5440 after 0.000057 second wait
Could not set interface wlan0 hwaddr: Too many open files in system
nl80211: failed to set_mac_addr for wlan0 to 96:a4:b3:79:fd:89
wlan0: Failed to set random MAC address
wlan0: Failed to assign random MAC address for a scan
and this is where that operation enabled by preassoc_mac_addr=1 is
failing in the driver..
dbus: org.freedesktop.DBus.Properties.Set (/fi/w1/wpa_supplicant1/Interfaces/1) [ssv]
properties_get_or_set: Set(MacAddr)
mac_addr=0
and that one does not exists either in upstream..
In other words, it looks like there are some custom changes in
wpa_supplicant and those changes are in the area that the used driver
does not support. I'd test what happens with that functionality (random
MAC address) disabled.
Hm, it looks like using random MAC addresses is not enabled in the NM's
gui for that connection, but it could be a bug in the gui.
I will try to hard-code the same MAC address as the device has, just in
case. And/or try without NM to take it out of the question.
Thanks for a quick reply, by the way.

# wpa_supplicant depends on strong random number generation being available
# from the operating system. os_get_random() function is used to fetch random
# data when needed, e.g., for key generation. On Linux and BSD systems, this
# works by reading /dev/urandom. It should be noted that the OS entropy pool
# needs to be properly initialized before wpa_supplicant is started. This is
# important especially on embedded devices that do not have a hardware random
# number generator and may by default start up with minimal entropy available
# for random number generation.
#
# As a safety net, wpa_supplicant is by default trying to internally collect
# additional entropy for generating random data to mix in with the data fetched
# from the OS. This by itself is not considered to be very strong, but it may
# help in cases where the system pool is not initialized properly. However, it
# is very strongly recommended that the system pool is initialized with enough
# entropy either by using hardware assisted random number generator or by
# storing state over device reboots.
#
# wpa_supplicant can be configured to maintain its own entropy store over
# restarts to enhance random number generation. This is not perfect, but it is
# much more secure than using the same sequence of random numbers after every
# reboot. This can be enabled with -e<entropy file> command line option. The
# specified file needs to be readable and writable by wpa_supplicant.
#
