From 777369237b1dfdd9bc11b855d8f08fe724b60c35 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Tue, 14 Jan 2014 12:35:49 +0200 Subject: [PATCH] iwlwifi: mvm: add predefined broadcast filter configuration Configure arp request broadcast filter if this option is enabled, in order to allow only arp request broadcasts to pass-in. (A following patch will make this filter even narrower by limiting the arp request to our own ip) Signed-off-by: Eliad Peller Signed-off-by: Emmanuel Grumbach --- drivers/net/wireless/iwlwifi/mvm/mac80211.c | 27 +++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/drivers/net/wireless/iwlwifi/mvm/mac80211.c b/drivers/net/wireless/iwlwifi/mvm/mac80211.c index 08b8051e56f8..6f9640b68771 100644 --- a/drivers/net/wireless/iwlwifi/mvm/mac80211.c +++ b/drivers/net/wireless/iwlwifi/mvm/mac80211.c @@ -128,6 +128,28 @@ static const struct wiphy_wowlan_tcp_support iwl_mvm_wowlan_tcp_support = { }; #endif +#ifdef CONFIG_IWLWIFI_BCAST_FILTERING +static const struct iwl_fw_bcast_filter iwl_mvm_default_bcast_filters[] = { + { + /* arp */ + .discard = 0, + .frame_type = BCAST_FILTER_FRAME_TYPE_ALL, + .attrs = { + { + /* frame type - arp, hw type - ethernet */ + .offset_type = + BCAST_FILTER_OFFSET_PAYLOAD_START, + .offset = sizeof(rfc1042_header), + .val = cpu_to_be32(0x08060001), + .mask = cpu_to_be32(0xffffffff), + }, + }, + }, + /* last filter must be empty */ + {}, +}; +#endif + static void iwl_mvm_reset_phy_ctxts(struct iwl_mvm *mvm) { int i; @@ -292,6 +314,11 @@ int iwl_mvm_mac_setup_register(struct iwl_mvm *mvm) } #endif +#ifdef CONFIG_IWLWIFI_BCAST_FILTERING + /* assign default bcast filtering configuration */ + mvm->bcast_filters = iwl_mvm_default_bcast_filters; +#endif + ret = iwl_mvm_leds_init(mvm); if (ret) return ret; -- GitLab
