According to issue #273:

[ +0.000036] UBSAN: shift-out-of-bounds in /root/tmp/rtl8188eus/hal/phydm/phydm_phystatus.c:1751:67
[ +0.000041] shift exponent 63 is too large for 32-bit type 'int'

where at hal/phydm/phydm_phystatus.c:1750-1751 following code is found:

i = 63;
sta->rssi_stat.ofdm_pkt_cnt -= (u8)((sta->rssi_stat.packet_map >> i) & BIT(0));

trying to fix it

sta->rssi_stat.packet_map is to be split as follows:

sta is struct cmn_sta_info defined in include/cmn_info/rtw_sta_info.h:188

struct cmn_sta_info {
        u16     dm_ctrl;
        enum channel_width      bw_mode;        /*max bandwidth*/
        u8      mac_id;
        u8      mac_addr[6];
        u16     aid;
        enum rf_type mimo_type;         /*sta XTXR*/
        struct rssi_info        rssi_stat;
        struct ra_sta_info      ra_info;
        u16     tx_moving_average_tp;   /*tx average MBps*/
        u16     rx_moving_average_tp;   /*rx average MBps*/
        u8      stbc_en:2;              /*Driver : really use stbc!!*/
        u8      ldpc_en:2;
        enum wireless_set       support_wireless_set;
#ifdef CONFIG_BEAMFORMING
        struct bf_cmn_info      bf_info;
#endif
        u8      sm_ps:2;
        struct dtp_info dtp_stat;       /*Dynamic Tx power offset*/
        /*u8            pw2cca_over_TH_cnt;*/
        /*u8            total_pw2cca_cnt;*/
};

rssi_stat is struct rssi_info defined in include/cmn_info/rtw_sta_info.h:148

struct rssi_info {
        s8              rssi;   
        s8              rssi_cck;
        s8              rssi_ofdm;
        u8              packet_map;     
        u8              ofdm_pkt_cnt;
        u8              cck_pkt_cnt;
        u16             cck_sum_power;
        u8              is_send_rssi;
        u8              valid_bit;
        s16             rssi_acc;       /*accumulate RSSI for per packet MA sum*/
};      

packet_map is u8 (short unsigned int) with size of 8 bits that's why shift can't be more than 8. the logic of code is a shift up to last bit of packet_map and next bitwise AND BIT(0) that's why shift is to be equal to 7.

@kimocoder could you please merge this?
