SD8997 firmware sends TLV_TYPE_MAX_CONN with struct hw_spec_max_conn to inform kernel about maximum number of p2p connections and stations in AP mode. During initialization of SD8997 wifi chip kernel prints warning: mwifiex_sdio mmc0:0001:1: Unknown GET_HW_SPEC TLV type: 0x217 This patch adds support for parsing TLV_TYPE_MAX_CONN (0x217) and sets appropriate cfg80211 member 'max_ap_assoc_sta' from retrieved structure. It allows userspace to retrieve NL80211_ATTR_MAX_AP_ASSOC_STA attribute. Signed-off-by:

The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from skb->data even when skb->len is less than ETH_ZLEN so it leads to a read overflow. The fix is to pad skb->data to at least ETH_ZLEN bytes. Cc: <stable@vger.kernel.org> Reported-by:

The CCK TX setting when switch channel will fix the CCK to path A only, so if the antenna is configured to path B (e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK packets can never be delivered to the air if only path B is connected with an antenna (it can possibly be transmitted through path A, but as path B is configured, the expected behavior is incorrect). This can also solve the racing issue of CCK TX setting between driver and firmware. The CCK TX setting in driver should be removed. Otherwise, the CCK TX setting would be wrong when the racing occurs. Fixes: 297bcf82 ("rtw88: add support for set/get antennas") Signed-off-by:

Connecting to an AP with WPA2 security may fail. The IQK and the EAPOL 4-way handshake may overlap because the driver does IQK right after assoc success. For 802.11n devices, the IQK is done in the driver and it could require more than 100ms to complete. During IQK, any TX/RX events are paused. So if the EAPOL 4-way handshake started before IQK finished, then the 1/4 and 2/4 part of the handshake could be dropped. The AP will then issue deauth with reason IEEE8021X_FAILED (23). To resolve this, move IQK routine into managed TX prepare (ieee80211_ops::mgd_prepare_tx()). The callback is called before the managed frames (auth/assoc) are sent. This will make sure that the IQK is completed before the handshake starts. But don't do IQK during scanning because doing it on each channel will take too long. For 802.11ac devices, the IQK is done in firmware and it takes less time to complete. Therefore we don't see a failure during the EAPOL 4-way handshake. But it is still worth moving the IQK into ieee80211_ops::mgd_prepare_tx(). Fixes: f5df1a8b ("rtw88: 8723d: Add 8723DE to Kconfig and Makefile") Tested-by:

Coex mechanism used to make BT have higher priority and more time to transfer data when BT inquiry-page, which leads to poor WiFi performance. Should take WiFi traffic into consideration. If the WiFi is having heavy traffic, use another parameter to make sure WiFi has more chance to TX/RX, while guarantee the priority of BT for inquiry. If the WiFi isn't busy (connected or not), set proper parameter to fix originals. Fixes: f5df1a8b ("rtw88: 8723d: Add 8723DE to Kconfig and Makefile") Tested-by:

Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43legacy did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43legacy will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers. Signed-off-by:

This reverts commit 07d0f553. For rtw88 driver, the SDIO is going to be supported, so there is no need to remove the SDIO related power sequence settings. And while the power sequence parser will pass in the mask of the HCI, the SDIO part will not be used to set registers accordingly. Moreover, the power sequence table is released as a whole package, so the next time if we are going to update, the SDIO settings will be overwritten. So, revert this now. Signed-off-by:

Range request version 10 keeps the same command size as version 9 but uses 2 reserved fields for the responder beacon interval and station id (if exists). For now, since the beacon interval of unassoc APs is unknown, use a value of 100 TUs which is a common value for many APs. While at it, remove the definition for CCMP_256 cipher, since this is not supported. Signed-off-by:
