Make Some Changes in firmae.config can make FirmAE Faster when facing a firmware image cannot be emulated.

[mwpeng2021]

First, thx for FirmAE tool. Very Useful. Then, I find a problem when facing a firmware image cannot be emulated, FirmAE will enter an infinite loop in firmae.config code. Details below. There is a "check_network" function in firmae.config.

while [ ${CURRENT_TIME} -le $[${START_TIME} + ${CHECK_TIMEOUT}] ]
    do
        for IP in "${IPS[@]}"
        do
            if (curl --max-time 2 --output /dev/null --silent http://${IP} || curl --max-time 2 --output /dev/null --silent https://${IP}); then
                t_end="$(date -u +%s.%N)"
                if (! ${WEB_RESULT}); then
                    WEB_TIME="$(bc <<< "$t_end-$t_start")"
                fi
                if (! ${PING_RESULT}); then
                    PING_TIME=${WEB_TIME}
                fi
                PING_RESULT=true
                WEB_RESULT=true
                RET_IP=${IP}
            fi
            if (ping -c 1 ${IP} > /dev/null); then
                t_end="$(date -u +%s.%N)"
                if (! ${PING_RESULT}); then
                    PING_TIME="$(bc <<< "$t_end-$t_start")"
                fi
                PING_RESULT=true
                RET_IP=${IP}
            fi
            sleep 1
            CURRENT_TIME=$(date +%s | bc)
        done
        if (${WEB_RESULT}); then
            break
        fi
    done

When the ${IPS[@]} is empty, IP is NONE and the for-loop will not be executed. So the CURRENT_TIME will always equals START_TIME. Therefore, the WHILE will be an infinite-loop and never break. So the simple solution put the code out of the FOR-loop and in the WHILE-loop.

while [ ${CURRENT_TIME} -le $[${START_TIME} + ${CHECK_TIMEOUT}] ]
    do
    CURRENT_TIME=$(date +%s | bc)
    ......
    done

Waiting 4 reply. Thx Again~.
