Re: [B.A.T.M.A.N.] [PATCH v2 0/7] batman-adv: wifi interface detection on

Hi,

Marek created some patches a while ago to automatically detect the wifi interface under virtual interfaces like VLANs. These patches had some problems because they failed to correctly set the num_bcasts in these situations and also had some locking problems.

The following patches try to address these by introducing a cache for the detected wifi configuration (wifi_flags which make taking the rtnl lock in critical section unnecessary) and by updating the num_bcast and wifi_flags when the interface behind iflink changes.

• added patch "batman-adv: Return non-const ptr in batadv_getlink_net"
• added patch "batman-adv: Close two alignment holes in batadv_hard_iface"
• added patch "batman-adv: Cache the type of wifi device for each hardif"
• added patch "batman-adv: Update wifi flags on upper link change"
• introduced batadv_get_real_netdevice which can be used inside rtnl locked contexts
• replaced wifi check functions with ones that use the wifi_flags cache
• use batadv_getlink_net to get the iflink net_namespace
• force rtnl_lock in batadv_get_real_netdev

Kind regards, Sven
