e837bdc8ad Update BusyBox
BusyBox is unable to run properly on non-root applications due to seccomp introduced in Android 8.0.
The SDK-21 libc.a has system call wrappers that uses the system calls on the whitelist, so binaries compiled with the updated libc can work properly.

7265450e2e Precise free space calculation for magisk.img
1. Introduce new applet: imgtool for better separation from the main program
2. Actually mount the image and check statvfs for free space in the image

This shall eliminate any possible module installation failure from image resizing issues.

312466aaf8 Prevent setting zero over than bound
The &cmd will return a pointer which point to a pointer of cmdline.
It is a memory address which is usually 8 bytes in 64 bits machine.

However, the struct cmdline is 4 bytes. This will cause setting zero
beyond the bound.

Below is a simple example to show the differentiation:

struct cmdline {
        char skip_initramfs;
        char slot[3];
};

static void parse_cmdline(struct cmdline *cmd)
{
        printf("%lu\n", sizeof(*cmd)); /* 4 */
        printf("%lu\n", sizeof(&cmd)); /* 8 */
}

int main()
{
        struct cmdline cmd;
        parse_cmdline(&cmd);
        return 0;
}

This patch prevents this.

44395e8ff0 Fix root loss issue when MagiskHide is enabled
In previous implementations, proc_monitor checks whether the mount namespace of an app is actually separated from zygote using a list generated at startup.
However, for some unknown reason, some devices (e.g. Samsung) has multiple zygote servers running in the background.
This means that app processes spawned from the unlisted zygotes are not checked whether the separation is done or not, causing MagiskHide unmount stuffs in the namespace of zygote, and since zygote is the "mother" of all apps, all apps will no longer have root access.

Since I'm not sure of the reason why multiple zygotes exists, so instead of checking the namespace against a list, compare the current namespace against the parent process's namespace.
This will make sure the namespace is NOT the same as the parent process, which is supposed to be the zygote server.

9929e7d8e8 Remove update file on boot
It's not important to check the return value of unlink(2) or even verify
that the file exists. If this code is running, it means the system has
rebooted, and thus the update file, if any, should be removed so that
MagiskManager doesn't keep displaying the same message. We also handle
this before we handle "disable" so that disabled modules don't keep
requesting a reboot to update.

a7ceb04cb7 Fix early mount on S9/S9+
Unlike other common OEMs, Samsung use uppper case partition name.

e.g: /dev/block/platform/11120000.ufs/by-name/SYSTEM

This will cause setup_block() fails to find a match partition.
Thus, we should use strcasecmp instead of strcmp.

b3cd83bbca magiskinit: Only unmount /system and /vendor if it was mounted by magisk
This fixes an issue where if /system or /vendor was already mounted
prior to magiskinit running, then they would get unmounted.
