My team and I are working on implementing multi-role on a single phy, during development we encountered an issue with channel switching events the current status is that the kernel should send a channel_switch_started event (pre-channel switch), however the event is not propagated through hostapd. the following patches are meant to deal with this situation. motivation: As an example, assuming we have a station connected to a far-AP, and the local-AP is working and transmitting. Now if the far-AP starts a CSA the process will fail and the station will disconnect since the local-AP holds the radio's channel. With this patch, I created an action script that requests a channel-switch to the same channel as the far-AP upon event received It works!! (both interfaces changed channel with no disconnects) In the future a user-space application will manage both interfaces and the switching scenarios more intelligently, so this patch-set is an infrastructure change for that application Omer Dagan (4): add callback for 'channel_switch_started' add 'channel_switch_started' event definitions added the event to the relevant switch statments modified the wpa_cli so the event will be acssible src/ap/drv_callbacks.c | 94 ++++++++++++++++++++++++++++++ src/common/wpa_ctrl.h | 2 + src/drivers/driver.h | 6 ++ src/drivers/driver_common.c | 1 + src/drivers/driver_nl80211_event.c | 76 ++++++++++++++++++++++++ wpa_supplicant/events.c | 14 +++++ wpa_supplicant/wpa_cli.c | 2 + 7 files changed, 195 insertions(+) -- 2.17.1 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
