Seven years ago we tried to fix a leak but actually introduced a double free instead. It was an understandable mistake because the code was a bit confusing and the free was done in the wrong place. The "skb" pointer is freed in both _rtl_usb_tx_urb_setup() and _rtl_usb_transmit(). The free belongs _rtl_usb_transmit() instead of _rtl_usb_tx_urb_setup() and I've cleaned the code up a bit to hopefully make it more clear. Fixes: 36ef0b47 ("rtlwifi: usb: add missing freeing of skbuff") Signed-off-by:

8723D adds some experimental features to word 0x06 of cam entry, so fill zeros to initialize them to off state. For existing chips, these two words are reserved and always zeros, so this change is harmless for them. Signed-off-by:

8723D is a Wifi+BT combo card. To make them work properly, we need coex mechanism to avoid interference, such as TX simultaneously. Basically, coex.c provide main algorithm to deal with many use cases, and this commit adds some parameters and ops differ from other chips, because coex hardware and WiFi generation are changed.

Since 8723D use different address of ltecoex register, this commit add a new field in chip_info and fill proper address. Then, ltecoex_read_reg() and ltecoex_reg_write() can use them to access ltecoex according to chip. Signed-off-by:

Flush queue is used to check if queue is empty, before doing something else. Since 8723D uses different registers and page number of availabl/reserved occupy 8 bits instead of 16 bits, so use a 'wsize' field to discriminate which rtw_read{8,16} is adopted. Signed-off-by: -

Without this patch, wifi card can't initialize properly due to BT in USB suspend state. So, we disable BT USB suspend (wakeup) in shutdown callback that is the moment before rebooting. To save BT USB power, we can't do this in 'remove' callback. Signed-off-by:

When chip's temperature is changed, RF characters are changed. To keep the characters to be consistent, 8723d uses thermal meter to assist in calibrating LCK, IQK, crystal and TX power. A base thermal value is programmed in efuse, all calibration data in MP process is based on this thermal value. So we calucate the delta of thermal value between the base value, and use this delta to reference XTAL and TX power offset tables to know how much we need to adjust. For IQK and LCK, driver checks if delta of thermal value is over 8, then they are triggered. For crystal adjustment, when delta of thermal value is changed, we check XTAL tables to get offset of XTAL value. If thermal value is larger than base value, positive table (_p as suffix) is used. Otherwise, we use negative table (_n as suffix). Then, we add offset to XTAL default value programmed in efuse, and write sum value to register. To compensate TX power, there are two hierarchical tables. First level use delta of thermal value to access eight tables to yield delta of TX power index. Then, plus base TX power index to get index of BB swing table (second level tables) where register value is induced. BB swing table can't deal with all cases, if index of BB swing table is over the size of the table. In this case, TX AGC is used to compensate the remnant part. Assume 'upper' is the upper bound of BB swing table, and 'target' is the desired index. Then, we can illustrate them as compensation method BB swing TX AGC ------------------- -------- -------------- target > upper upper target - upper target < 0 0 target otherwise target 0 For debug purpose, add a column 'rem' to tx_pwr_tbl entry, and it looks like path rate pwr base (byr lmt ) rem A CCK_1M 32(0x20) 34 -2 ( 0 -2) 0 Signed-off-by: -

IQ calibration is used to calibrate RF characteristic to yield expected performance. Basically, we do calibration twice and compare the similarity to determine calibration is good or not, if not we do the third calibration, and then compare with the results of first and second calibration. If it still not similar, IQK is failed. Before doing calibration, we need to backup registers that will be modified in calibration procedure, and restore these registers after calibration is done. A calibration procedure can divided into four sub-procedures that are S1-TX, S1-RX, S0-TX and S0-RX. Where, S1 and S0 represent to path A and B respectively. Each sub-procedure configure proper registers, and then rigger one-shot calibration and poll until completion. For RX calibration, it needs to do twice one-shot calibration, first one is to yield parameter used by second one. The result of TX part is stored for TX power tracking that adjusts TX AGC to output expected power. Signed-off-by:

An incorrect value of use_fwsup is set for 4-way handshake offload for WPA//WPA2-PSK, caused by commit 3b1e0a7b ("brcmfmac: add support for SAE authentication offload"). It results in missing bit BRCMF_VIF_STATUS_EAP_SUCCESS set in brcmf_is_linkup() and causes the failure. This patch correct the value for the case. Also setting bit BRCMF_VIF_STATUS_EAP_SUCCESS for SAE offload case in brcmf_is_linkup() to fix SAE offload failure.
