From fd1a54c14bd93166784c2adfaf1f4f22c597e963 Mon Sep 17 00:00:00 2001 From: Miri Korenblit Date: Mon, 20 Mar 2023 12:33:10 +0200 Subject: [PATCH] wifi: iwlwifi: mvm: add stop_ap() and leave_ibss() callbacks for MLD mode This is another patch in the series adding all the ops for the new MLD ieee80211_ops. The callbacks added here use the new MLD FW API Signed-off-by: Miri Korenblit Signed-off-by: Gregory Greenman Link: https://lore.kernel.org/r/20230320122330.42b0d4726b8d.I0755baace47c0ab1d9d70137448125d3140ef3af@changeid Signed-off-by: Johannes Berg --- drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c | 22 +++++++++++----- .../net/wireless/intel/iwlwifi/mvm/mld-mac80211.c | 30 ++++++++++++++++++++++ drivers/net/wireless/intel/iwlwifi/mvm/mvm.h | 2 ++ 3 files changed, 48 insertions(+), 6 deletions(-) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c b/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c index 165358a4a97e..c6eb4cb44a09 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c @@ -2826,16 +2826,15 @@ static int iwl_mvm_start_ibss(struct ieee80211_hw *hw, return iwl_mvm_start_ap_ibss(hw, vif, &vif->bss_conf); } -static void iwl_mvm_stop_ap_ibss(struct ieee80211_hw *hw, - struct ieee80211_vif *vif, - struct ieee80211_bss_conf *link_conf) +/* Common part for MLD and non-MLD ops */ +void iwl_mvm_stop_ap_ibss_common(struct iwl_mvm *mvm, + struct ieee80211_vif *vif) { - struct iwl_mvm *mvm = IWL_MAC80211_GET_MVM(hw); struct iwl_mvm_vif *mvmvif = iwl_mvm_vif_from_mac80211(vif); - iwl_mvm_prepare_mac_removal(mvm, vif); + lockdep_assert_held(&mvm->mutex); - mutex_lock(&mvm->mutex); + iwl_mvm_prepare_mac_removal(mvm, vif); /* Handle AP stop while in CSA */ if (rcu_access_pointer(mvm->csa_vif) == vif) { @@ -2860,6 +2859,17 @@ static void iwl_mvm_stop_ap_ibss(struct ieee80211_hw *hw, } iwl_mvm_bt_coex_vif_change(mvm); +} + +static void iwl_mvm_stop_ap_ibss(struct ieee80211_hw *hw, + struct ieee80211_vif *vif, + struct ieee80211_bss_conf *link_conf) +{ + struct iwl_mvm *mvm = IWL_MAC80211_GET_MVM(hw); + + mutex_lock(&mvm->mutex); + + iwl_mvm_stop_ap_ibss_common(mvm, vif); /* Need to update the P2P Device MAC (only GO, IBSS is single vif) */ if (vif->p2p && mvm->p2p_device_vif) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c b/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c index 866415dc40bc..f800bf0b6d90 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c @@ -322,10 +322,40 @@ out_unlock: return ret; } +static void iwl_mvm_mld_stop_ap_ibss(struct ieee80211_hw *hw, + struct ieee80211_vif *vif) +{ + struct iwl_mvm *mvm = IWL_MAC80211_GET_MVM(hw); + + mutex_lock(&mvm->mutex); + + iwl_mvm_stop_ap_ibss_common(mvm, vif); + + /* Need to update the P2P Device MAC (only GO, IBSS is single vif) */ + if (vif->p2p && mvm->p2p_device_vif) + iwl_mvm_mld_mac_ctxt_changed(mvm, mvm->p2p_device_vif, false); + + iwl_mvm_ftm_responder_clear(mvm, vif); + + iwl_mvm_mld_rm_bcast_sta(mvm, vif); + iwl_mvm_mld_rm_mcast_sta(mvm, vif); + + /* Link needs to be deactivated before removal */ + iwl_mvm_link_changed(mvm, vif, LINK_CONTEXT_MODIFY_ACTIVE, false); + iwl_mvm_remove_link(mvm, vif); + + iwl_mvm_power_update_mac(mvm); + + iwl_mvm_mld_mac_ctxt_remove(mvm, vif); + + mutex_unlock(&mvm->mutex); +} + const struct ieee80211_ops iwl_mvm_mld_hw_ops = { .add_interface = iwl_mvm_mld_mac_add_interface, .remove_interface = iwl_mvm_mld_mac_remove_interface, .assign_vif_chanctx = iwl_mvm_mld_assign_vif_chanctx, .unassign_vif_chanctx = iwl_mvm_mld_unassign_vif_chanctx, .join_ibss = iwl_mvm_mld_start_ap_ibss, + .leave_ibss = iwl_mvm_mld_stop_ap_ibss, }; diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h b/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h index a21ccbfd017c..a03c2e5bbc25 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h @@ -1769,6 +1769,8 @@ int iwl_mvm_remove_link(struct iwl_mvm *mvm, struct ieee80211_vif *vif); /* AP and IBSS */ bool iwl_mvm_start_ap_ibss_common(struct ieee80211_hw *hw, struct ieee80211_vif *vif, int *ret); +void iwl_mvm_stop_ap_ibss_common(struct iwl_mvm *mvm, + struct ieee80211_vif *vif); /* Quota management */ static inline size_t iwl_mvm_quota_cmd_size(struct iwl_mvm *mvm) -- 2.11.0
