 Posted: Thu Jul 09, 2015 1:20 pm Post subject: nl80211: Could not re-add multicast membership |
 |
|
Hey Guys!
I'm trying for hours to solve this problem and found nowhere else an answer. Always I boot or start wpa_supplicant I got the error:
| Code: |
nl80211: Could not re-add multicast membership for vendor events: -2 (No such file or directory)
|
I got the following hardware:
| Code: |
*-network
description: Wireless interface
product: Centrino Advanced-N 6205 [Taylor Peak]
vendor: Intel Corporation
physical id: 0
bus info: pci@0000:03:00.0
logical name: wlan0

serial: 08:11:96:3d:17:90

resources: irq:47 memory:b0600000-b0601fff
|
and I use the nl80211 Driver. Question in between: why is the driver iwlwifi listed above when I use the nl80211?
Here is a piece of output of: wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant_A_S.conf -D nl80211 -d

Kind of regards

Are you confused about having those two drivers?
The one is for the network stack and the other for the nic. |

Thanks for the answer 
But my main Problem is still present: nl80211: Could not add multicast membership for vendor events: -2 (No such file or directory)
why did it appear and how can I solve this?
Could anybody help me please? |

royalts ... that doesn't look kosher to me, and while you haven't provided the contents of wpa_supplicant_A_S.conf the above suggests you are setting 'ctrl_interface_group=' and 'GROUP' ... the former to '0' (root) and the latter to 'wheel'. I speculate this is the reason behind the subsequent "No such file or directory". If I'm correct then remove the 'ctrl_interface_group' entry from the config ...

Hey,
you were right! I had such entries in my config. Unfortunately, the problem persists after comment those lines out
and my config looks like:
| Quote: |
#ctrl_interface_group=0
ap_scan=1
# Allow users in the 'wheel' group to control wpa_supplicant
#ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
# Make this file writable for wpa_gui
update_config=1
eapol_version=1
network={
ssid="A/S"
priority=1
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=TKIP CCMP
psk="**********
}
|
and the comannd I execute wpa_supplicant:
| Code: |
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant_A_S.conf -D nl80211

?????
Why do you think you need to comment out that line? |

Yes, you are right. But there are no differences. If I uncomment this line I will get the same error...
Now the config file looks like:
| Code: |
#ctrl_interface_group=0
ap_scan=1
# Allow users in the 'wheel' group to control wpa_supplicant
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
# Make this file writable for wpa_gui
#update_config=1
.....

The message you are receiving is from driver_nl80211.c of wpa_supplicant: | Code: | static void nl80211_check_global(struct nl80211_global *global)
{
struct nl_handle *handle;
const char *groups[] = { "scan", "mlme", "regulatory", "vendor", NULL };
int ret;
unsigned int i;
/*
* Try to re-add memberships to handle case of cfg80211 getting reloaded
* and all registration having been cleared.
*/
handle = (void *) (((intptr_t) global->nl_event) ^
ELOOP_SOCKET_INVALID);
for (i = 0; groups[i]; i++) {
ret = nl_get_multicast_id(global, "nl80211", groups[i]);
if (ret >= 0)
ret = nl_socket_add_membership(handle, ret);
if (ret < 0) {
wpa_printf(MSG_INFO,
"nl80211: Could not re-add multicast membership for %s events: %d (%s)",
groups[i], ret, strerror(-ret));
}
}
}

Yes, but I think the issue probably lies with the kernel driver for whatever card the OP has ... anyhow, royalts, I don't think this is serious, you could try and suppress the error with the following:
/etc/conf.d/net
| Code: | | wpa_supplicant_wlan0="-Dnl80211 -qq" |
... or simply adding '-qq' to your command.
HTH & best ... khay |
