From f8a77dbb88377b16760bc6e1881630f2e3dcaff4 Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Tue, 13 Sep 2022 12:43:58 +0800 Subject: [PATCH] wifi: ath11k: Include STA_KEEPALIVE_ARP_RESPONSE TLV header by default [ Upstream commit b7b6f86149a7e06269d61a7a5206360f5b642f80 ] In current code STA_KEEPALIVE_ARP_RESPONSE TLV header is included only when ARP method is used, this causes firmware always to crash when wowlan is enabled because firmware needs it to be present no matter ARP method is used or not. Fix this issue by including STA_KEEPALIVE_ARP_RESPONSE TLV header by default. Also fix below typo: s/WMI_TAG_STA_KEEPALVE_ARP_RESPONSE/WMI_TAG_STA_KEEPALIVE_ARP_RESPONSE/ Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3 Fixes: 0f84a156aa3b ("ath11k: Handle keepalive during WoWLAN suspend and resume") Signed-off-by: Baochen Qiang Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220913044358.2037-1-quic_bqiang@quicinc.com Signed-off-by: Sasha Levin --- drivers/net/wireless/ath/ath11k/wmi.c | 9 +++++---- drivers/net/wireless/ath/ath11k/wmi.h | 2 +- 2 files changed, 6 insertions(+), 5 deletions(-) diff --git a/drivers/net/wireless/ath/ath11k/wmi.c b/drivers/net/wireless/ath/ath11k/wmi.c index cc84bd53ddae9..1c8aa503e6144 100644 --- a/drivers/net/wireless/ath/ath11k/wmi.c +++ b/drivers/net/wireless/ath/ath11k/wmi.c @@ -9003,12 +9003,13 @@ int ath11k_wmi_sta_keepalive(struct ath11k *ar, cmd->interval = arg->interval; cmd->method = arg->method; + arp = (struct wmi_sta_keepalive_arp_resp *)(cmd + 1); + arp->tlv_header = FIELD_PREP(WMI_TLV_TAG, + WMI_TAG_STA_KEEPALIVE_ARP_RESPONSE) | + FIELD_PREP(WMI_TLV_LEN, sizeof(*arp) - TLV_HDR_SIZE); + if (arg->method == WMI_STA_KEEPALIVE_METHOD_UNSOLICITED_ARP_RESPONSE || arg->method == WMI_STA_KEEPALIVE_METHOD_GRATUITOUS_ARP_REQUEST) { - arp = (struct wmi_sta_keepalive_arp_resp *)(cmd + 1); - arp->tlv_header = FIELD_PREP(WMI_TLV_TAG, - WMI_TAG_STA_KEEPALVE_ARP_RESPONSE) | - FIELD_PREP(WMI_TLV_LEN, sizeof(*arp) - TLV_HDR_SIZE); arp->src_ip4_addr = arg->src_ip4_addr; arp->dest_ip4_addr = arg->dest_ip4_addr; ether_addr_copy(arp->dest_mac_addr.addr, arg->dest_mac_addr); diff --git a/drivers/net/wireless/ath/ath11k/wmi.h b/drivers/net/wireless/ath/ath11k/wmi.h index b1fad4707dc60..ca3b9a384d605 100644 --- a/drivers/net/wireless/ath/ath11k/wmi.h +++ b/drivers/net/wireless/ath/ath11k/wmi.h @@ -1214,7 +1214,7 @@ enum wmi_tlv_tag { WMI_TAG_NS_OFFLOAD_TUPLE, WMI_TAG_FTM_INTG_CMD, WMI_TAG_STA_KEEPALIVE_CMD, - WMI_TAG_STA_KEEPALVE_ARP_RESPONSE, + WMI_TAG_STA_KEEPALIVE_ARP_RESPONSE, WMI_TAG_P2P_SET_VENDOR_IE_DATA_CMD, WMI_TAG_AP_PS_PEER_CMD, WMI_TAG_PEER_RATE_RETRY_SCHED_CMD, -- 2.47.2
