Maybe i'm stupid but I guess it's something?

ZE HYPE IST REEL!

 

[NodePoint]

Steveice10 just added some gotoes into his code. Just saying. (I personally don't like them)

This: https://github.com/JustPingo/KernelTimeMachine/blob/master/source/main.c#L200

 

[Mrrraou]

Don't hype yet, it doesn't run on 9.3 and upper.

That was exactly my point. Goto is much easier to read and maintain for cleanup then tens of nested ifelses. So calling code in c crap because it uses goto shows low experience in programming. It's not your favorite Java where you can use try finally.

int initRTC()
{
    char *buf1, *buf2;
    int ret = RTC_OK;
    if ((buf1 = (char *)malloc(20)) == NULL) {
        ret = ERR_RTC_MALLOC1;
    }
    else if ((buf2 = (char *)malloc(40)) == NULL) {
        ret = ERR_RTC_MALLOC2;
    }
    else if (openRTC()) {
        ret = ERR_RTC_OPEN;
    }
    else if (cfgRTC(buf1, 20, buf2, 40)) {
        ret = ERR_RTC_CFG;
    }
    else if (txCmd(buf1, 20, buf2, 40)) {
        ret = ERR_RTC_TX;
    }
    if (ret >= ERR_RTC_CFG) {
        closeRTC();
    }
    if (ret >= ERR_RTC_OPEN) {
        free(buf2);
    }
    if (ret >= ERR_RTC_MALLOC2) {
        free(buf1);
    }
    return ret;
}

int initRTC()
{
    char *buf1, *buf2;
    int ret = RTC_OK;
    if ((buf1 = (char *)malloc(20)) == NULL) {
        ret = ERR_RTC_MALLOC;
        goto fim0;
    }
    if ((buf2 = (char *)malloc(40)) == NULL) {
        ret = ERR_RTC_MALLOC;
        goto fim1;
    }
    if (openRTC()) {
        ret = ERR_RTC_OPEN;
        goto fim2;
    }
    if (cfgRTC(buf1, 20, buf2, 40)) {
        ret = ERR_RTC_CFG;
        goto fim3;
    }
    if (txCmd(buf1, 20, buf2, 40)) {
        ret = ERR_RTC_TX;
        goto fim3;
    }
fim3:
    closeRTC();
fim2:
    free(buf2);
fim1:
    free(buf1);
fim0:
    return ret;
}

Which one is easier to read/maintain? Now can you all please just shut-up while people that actually know any better do their job?!

 

[ihaveahax]

I have to question why they merged the files back as well...

 

[A_Random_Guy]

Don't hype yet, it doesn't run on 9.3 and upper.

YET

 

[Mrrraou]

YET

They are working on it.

 

[bbcali89]

Don't hype yet, it doesn't run on 9.3 and upper.

I noticed this too. odd.
is it general ? or do they have to make a version for each fw ?

 

[Substance12]

At least it can run code now.

 

[Lycan911]

HOLY SHIT MY TAPATALK NOTIFICATIONS ARE BEEPING LIKE CRAZY [emoji38]

 

[Deleted member 373223]

Don't hype yet, it doesn't run on 9.3 and upper.

wait, steveice10 doesn't need basical code execution on 9.3+? why he maked a 9.2- thing?

 

[bbcali89]

with this new info... it's coming today guaranteed guys. unless they hold back. which they might. who knows.

 

[Mrrraou]

We tried on 10.1, 9.2 and 9.0.

--------------------- MERGED ---------------------------

They didn't do a 9.2 thing, as it crashes on 9.2 and 9.0 too.

not garantueed. but maybe 1 or 2 or 3 days.

ahhhhhhhh. can it load code on 9.3+?

we... ahh so you can confirm the exploit is working. huh?

I don't see how basic kernel code execution leads you to believe that the hax is coming today, but whatever makes you feel good.

 

[Mrrraou]

Not yet. There is still work to be done.

interesting. well it becomes more and more a hot topic.

The code in memchunkhax is very different. Use single cleanup logic and add actions beteen validity checks and ifelse approach looses without options.
