Use it to filter them out and pass to the -monitor interface. These defines were found in bcmmsgbuf.h from SDK. - -As not every firmware generates radiotap header this commit introduces -BRCMF_FEAT_MONITOR_FMT_RADIOTAP flag. It has to be has based on firmware -capabilities. If not present brcmf_netif_mon_rx() will assume packet is -a raw 802.11 frame and will prepend it with an empty radiotap header. - -This new code is limited to the msgbuf protocol at this point. Adding -support for SDIO/USB devices will require some extra work (possibly a -new firmware release). - -Signed-off-by: Rafał Miłecki <rafal@milecki.pl> -Acked-by: Arend van Spriel <arend.vanspriel@broadcom.com> -Signed-off-by: Kalle Valo <kvalo@codeaurora.org> ---- - .../wireless/broadcom/brcm80211/brcmfmac/core.c | 25 ++++++++++++++++++++++ - .../wireless/broadcom/brcm80211/brcmfmac/core.h | 2 ++ - .../wireless/broadcom/brcm80211/brcmfmac/msgbuf.c | 18 ++++++++++++++++ - 3 files changed, 45 insertions(+) - ---- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.c -+++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.c -@@ -21,6 +21,7 @@ - #include <net/cfg80211.h> - #include <net/rtnetlink.h> - #include <net/addrconf.h> -+#include <net/ieee80211_radiotap.h> - #include <net/ipv6.h> - #include <brcmu_utils.h> - #include <brcmu_wifi.h> -@@ -404,6 +405,30 @@ void brcmf_netif_rx(struct brcmf_if *ifp - netif_rx_ni(skb); - } - -+void brcmf_netif_mon_rx(struct brcmf_if *ifp, struct sk_buff *skb) -+{ -+ if (brcmf_feat_is_enabled(ifp, BRCMF_FEAT_MONITOR_FMT_RADIOTAP)) { -+ /* Do nothing */ -+ } else { -+ struct ieee80211_radiotap_header *radiotap; -+ -+ /* TODO: use RX status to fill some radiotap data */ -+ radiotap = skb_push(skb, sizeof(*radiotap)); -+ memset(radiotap, 0, sizeof(*radiotap)); -+ radiotap->it_len = cpu_to_le16(sizeof(*radiotap)); -+ -+ /* TODO: 4 bytes with receive status? */ -+ skb->len -= 4; -+ } -+ -+ skb->dev = ifp->ndev; -+ skb_reset_mac_header(skb); -+ skb->pkt_type = PACKET_OTHERHOST; -+ skb->protocol = htons(ETH_P_802_2); -+ -+ brcmf_netif_rx(ifp, skb); -+} -+ - static int brcmf_rx_hdrpull(struct brcmf_pub *drvr, struct sk_buff *skb, - struct brcmf_if **ifp) - { ---- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.h -+++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.h -@@ -121,6 +121,7 @@ struct brcmf_pub { - - struct brcmf_if *iflist[BRCMF_MAX_IFS]; - s32 if2bss[BRCMF_MAX_IFS]; -+ struct brcmf_if *mon_if; - - struct mutex proto_block; - unsigned char proto_buf[BRCMF_DCMD_MAXLEN]; -@@ -216,6 +217,7 @@ void brcmf_txflowblock_if(struct brcmf_i - enum brcmf_netif_stop_reason reason, bool state); - void brcmf_txfinalize(struct brcmf_if *ifp, struct sk_buff *txp, bool success); - void brcmf_netif_rx(struct brcmf_if *ifp, struct sk_buff *skb); -+void brcmf_netif_mon_rx(struct brcmf_if *ifp, struct sk_buff *skb); - void brcmf_net_setcarrier(struct brcmf_if *ifp, bool on); - int __init brcmf_core_init(void); - void __exit brcmf_core_exit(void); ---- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/msgbuf.c -+++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/msgbuf.c -@@ -69,6 +69,8 @@ - #define BRCMF_MSGBUF_MAX_EVENTBUF_POST 8 - - #define BRCMF_MSGBUF_PKT_FLAGS_FRAME_802_3 0x01 -+#define BRCMF_MSGBUF_PKT_FLAGS_FRAME_802_11 0x02 -+#define BRCMF_MSGBUF_PKT_FLAGS_FRAME_MASK 0x07 - #define BRCMF_MSGBUF_PKT_FLAGS_PRIO_SHIFT 5 - - #define BRCMF_MSGBUF_TX_FLUSH_CNT1 32 -@@ -1128,6 +1130,7 @@ brcmf_msgbuf_process_rx_complete(struct - struct sk_buff *skb; - u16 data_offset; - u16 buflen; -+ u16 flags; - u32 idx; - struct brcmf_if *ifp; - -@@ -1137,6 +1140,7 @@ brcmf_msgbuf_process_rx_complete(struct - data_offset = le16_to_cpu(rx_complete->data_offset); - buflen = le16_to_cpu(rx_complete->data_len); - idx = le32_to_cpu(rx_complete->msg.request_id); -+ flags = le16_to_cpu(rx_complete->flags); - - skb = brcmf_msgbuf_get_pktid(msgbuf->drvr->bus_if->dev, - msgbuf->rx_pktids, idx); -@@ -1150,6 +1154,20 @@ brcmf_msgbuf_process_rx_complete(struct - - skb_trim(skb, buflen); - -+ if ((flags & BRCMF_MSGBUF_PKT_FLAGS_FRAME_MASK) == -+ BRCMF_MSGBUF_PKT_FLAGS_FRAME_802_11) { -+ ifp = msgbuf->drvr->mon_if; -+ -+ if (!ifp) { -+ brcmf_err("Received unexpected monitor pkt\n"); -+ brcmu_pkt_buf_free_skb(skb); -+ return; -+ } -+ -+ brcmf_netif_mon_rx(ifp, skb); -+ return; -+ } -+ - ifp = brcmf_get_ifp(msgbuf->drvr, rx_complete->msg.ifidx); - if (!ifp || !ifp->ndev) { - brcmf_err("Received pkt for invalid ifidx %d\n", |
