2ff5d9606b magiskboot: add support for remaining Nook HD pre-image loaders 2019-05-19 17:38:41 -07:00

80cd85b061 Try to use broadcast for su logging and notify
In commit 8d4c407, native Magisk always launches an activity for
communicating with Magisk Manager. While this works extremely well,
since it also workaround stupid OEMs that blocks broadcasts, it has a
problem: launching an activity will claim the focus of the device,
which could be super annoying in some circumstances.

This commit adds a new feature to run a broadcast test on boot complete.
If Magisk Manager successfully receives the broadcast, it will toggle
a setting in magiskd so all future su loggings and notifies will always
use broadcasts instead of launching activities.

Fix #1412

415ff23be5 Fix error mounting /data partition
For devices come with two /data mount points, magisk will bind the one in tmpfs and failed to load modules since this partition is empty.

003e44fb84 Remove requirement to use early-init daemon
We used to construct /sbin tmpfs overlay in early-init stage after
SELinux is properly initialized. However the way it is implemented
(forking daemon from magiskinit with complicated file waiting triggers)
is extremely complicated and error prone.

This commit moves the construction of the sbin overlay to pre-init
stage. The catch is that since SELinux is not present at that point,
proper selabel has to be reconstructed afterwards. Some additional
SEPolicy rules are added to make sure init can access magisk binaries,
and the secontext relabeling task is assigned to the main Magisk daemon.

515f346dcc Monitor app_process
Some stupid Samsung ROMs will spawn multiple zygote daemons. Since we
switched to ptrace based process monitoring, we have to know all zygote
processes to trace. This is an attempt to fix this issue.

8d4c407201 Directly communicate with Activity
Since Android Q does not allow launching activities from the background
(Services/BroadcastReceivers) and our native process is root, directly
launch activities and use it for communication between native and app.

The target activity is not exported, so non-root apps cannot send an
intent to fool Magisk Manager. This is as safe as the previous
implementation, which uses protected system broadcasts.

This also workaround broadcast limitations in many ROMs (especially
in Chinese ROMs) which blocks the su request dialog if the app is
frozen/force stopped by the system.

f24df4f43d Don't allow cloning root nodes
The root nodes are /system and /vendor. Adding new files into these
directories, although works on some devices, mostly bootloops on many
devices out there. So don't allow it, which also makes the whole magic
mounting logic much easier and extensible.

24f5bc98d8 Add boot_complete trigger back
Samsung does not like running cmd before system services are started.
Instead of failing, it will enter an infinite wait on binder.
Move APK installation to boot complete to make sure pm can be run

71a91ac7a7 Boot to recovery if volume up key is held
Forseeing the future that more and more A only system-as-root devices
would have similar bootloader behavior as the latest Samsung devices
(that is, no ramdisk will be loaded into memory when booting from
the boot partition), a solution/workaround has to be made when Magisk
is installed to the recovery partition, making custom recoveries
unable to co-exist with Magisk.

This commit allows magiskinit to read input device events from the
kernel to detect when a user holds volume key up to toggle whether
system-as-root mode is enabled. When system-as-root mode is disabled,
magiskinit will boot with ramdisk instead of cloning rootfs from system,
which in this case will boot to the recovery.

1cd45b53b1 Support recovery based Magisk
Some devices (mainly new Samsung phones we're talking here...) using
A only system-as-root refuse to load ramdisk when booted with boot
no matter what we do. With many A only system-as-root devices, even
though their boot image is kernel only, we can still be able to add
a ramdisk section into the image and force the kernel to use it as
rootfs. However the bootloader on devices like the S10 simply does
not load anything within boot image into memory other than the kernel.
This gives as the only option is to install Magisk on the recovery
partition. This commits adds proper support for these kind of scenarios.

9bb2243b56 Switch to skip_mount instead of auto_mount
95%+ of existing modules enables auto mount (obviously).
Switching auto mount to opt-out makes more sense than opt-in as
in previous module format. The file 'auto_mount' will be ignored, and
the file 'skip_mount' will be checked to toggle the mounting behavior.

After scanning through the current Magisk Module Repo modules, no
modules are using custom bind mounting; all modules with auto mount
disabled have empty system folder, which means this change will not
affect any existing module.

the sepolicy loading to Android Q only.

e476c18c99 Don't load sepolicy on Huawei devices
Of course, the cancer of Android, Huawei, has to do some f**king weird
modifications to the Linux kernel. Its kernel only accepts 1 single
policy load in its lifetime, a second load will result in ENOMEM error.
Since Huawei devices always use their own stupid ramdisk setup and not
system-as-root, not loading sepolicy is not a concern (for now).
