Dear Debian folks,


the `brcmsmac` [1] module does not support IBSS [2] needed to create
ad-hoc networks [3][4][5].

This prevents for example using shared WLAN connections from smart
phones. `/var/log/syslog` contains the following messages.

    ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement)
    ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: disassociated
    ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled false, count 1
    wpa_supplicant[2209]: nl80211: Failed to set interface into IBSS mode
    wpa_supplicant[2209]: Association request to the driver failed

     1. Would it be better to use the module `b43` by default which is
        supposed to support all modes [3]?
     2. If support for IBSS in `brcmsmac` is implemented, could that be
        backported to Linux 3.2?

For interested people, Broadcom’s proprietary `wl` driver supports IBSS
too.

The WLAN controller in this system is identified by `lspci` as

    08:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

and Broadcom’s proprietary driver `wl` identifies the following.

    wlan0: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.100.82.112


Thanks,

Paul

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
