Hi,
I am working on a project , where WLAN is a full mac device. I need to enable softap .
MLME for access point mode gets handled inside firmware . In that case , do I need to disable NEED_AP_MLME in Hostapd build configuration .
But it seems by default NEED_AP_MLME is enabled with driver_nl80211.
Will it be correct to disable the NEED_AP_MLME or any other alternative is available . Please suggest.
I am looking at wpa_supplicant version '2.0-devel' codebase ( Android Jellybean 4.3 AOSP).
Regards
Dhanajit

Hi,
This patch is to support IEEE80211R FT-OVER-DS when use driver as SME.
When use command FT_DS <MAC Adress>, FT action will be refused when not use wpa supplicant as SME.
As follow:
if (!(wpa_s->drv_flags & WPA_DRIVER_FLAGS_SME))
return; /* only SME case supported for now */ Delete this check, and add some other changes to support ft-over-ds when use driver as SME.
This changes will not affect ft-over-ds when use WPA supplicant as SME.
Thanks
BR

If more BSS networks are added in config file than are supported by the driver, segmantation fault can appear.
For this case clean interface_added flag is needed when adding new BSS failed.

Without this fix I saw segmantation fault or
"wlan0: Could not connect to kernel driver" in hostapd when I added more BSS networks in config file than are supported by the driver. For example when I created the following BSSs in config file:
1) wlan0
2) wlan0-1
3) wlan0-2
4) wlan0-3
and the last one couldn't be added because it wasn't supported by the driver, I received the following debug print:
nl80211: Adding interface wlan0-3 into bridge br-lan Could not set interface wlan0-3 flags (UP): Device or resource busy
After that when I killed hostapd, it tried to remove wlan0-3 and delete global bss pointer - wlan0

If I am not mistaken you need either monitor interface or support for
mgmt_rx. brcmfmac has mgmt_rx support.

The bad news is the kernel version. I think 3.4 will give some issues
using brcmfmac in AP mode.
