- the strings fallback was broken when the preceding character changed from 5 to ! recently, this new regex should cover any preceding character going forward
If we assign the execution output directly it will fail (tested on Android 11):
pdx201:/ # INSTALLER=/data/adb/magisk_install /data/adb/magisk_install/flash_script.sh
/data/adb/magisk_install/flash_script.sh[31]: typeset: -o: is not an identifier
Because:
local cmds=$($bb sh -o standalone -c "
for arg in \$(tr '\0' '\n' < /proc/$$/cmdline); do
if [ -z \"\$cmds\" ]; then
# Skip the first argument as we want to change the interpreter
cmds=\"sh -o standalone\"
else
cmds=\"\$cmds '\$arg'\"
fi
done
echo \$cmds")
/system/bin/sh: typeset: -o: is not an identifier

Previously, Magisk uses persist or cache for storing modules' custom
sepolicy rules. In this commit, we significantly broaden its
compatibility and also prevent mounting errors.
The persist partition is non-standard and also critical for Snapdragon
devices, so we prefer not to use it by default.
We will go through the following logic to find the best suitable
non-volatile, writable location to store and load sepolicy.rule files:
Unencrypted data -> FBE data unencrypted dir -> cache -> metadata -> persist
This should cover almost all possible cases: very old devices have
cache partitions; newer devices will use FBE; latest devices will use
metadata FBE (which guarantees a metadata parition); and finally,
all Snapdragon devices have the persist partition (as a last resort).
Fix#3179
- LOS Recovery can't decrypt or even mount /data, thus the installer can't do everything it needs to do and must abort, so also suggest uninstall via Manager at that point
- fix removal of addon.d script when uninstall is run via Manager on SAR
- fix removal of addon.d with dynamic/logical partitions via mapper
- Do not attempt to patch DTB anywhere outside of boot images as they
are no longer essential. This makes Magisk installation to only modify
strictly boot/recovery partitions again.
- The only required patch for DTB is to strip verity out of partitions
- /vendor is used only on some older devices for recovery AVBv1 signing so is not critical if fails
- this fixes installation in Lineage Recovery on some older devices where /vendor is actually by-name partitions like oem, cust (or even cache), which likely also don't require the AVBv1 signing
- bugged TWRPs were filling persist with recovery logs, so clean those as a potential workaround
- abort module install if sepolicy.rule fails to copy, since 99% of the time the module wouldn't include it if it could function without it
Closes#2461
- try /dev/block first with full depth to catch all platform/soc variations to the by-name directory, and the new dynamic partition /dev/block/mapper
- next try uevent for block devices as before
- lastly try /dev with maxdepth 1 (immediate directory) to find /dev/bootimg, /dev/recovery, etc. while avoiding /dev/log/kernel
- move bootimg higher in the list than boot so /dev/bootimg gets found first and avoids /dev/BOOT
- recovery_a/_b now also exists
- minor touch-ups for readability and consistency
Fixes#2720
- this is needed for installations on Lineage 17.1 Recovery (AOSP Q) for logical partition devices, which uses /dev/block/mapper to stage the partitions
Thanks LuK1337 & erfanoabdi @ Lineage
- /proc/$$/cmdline is \0 terminated argument strings except for the last argument which has no terminus, so the last argument was being dropped by `while read` which requires input to be \n terminated
- switch to a for loop, which will use the \n delimiter but also read the last argument; all arguments are still protected by quoting
- clean up potentially breaking recovery env since $OLD_PATH no longer exists
* Lineage Recovery 17.1, like AOSP Q recovery, has '/' as a shared
mount point, causing `mount --move` to fail.
If it fails, directly mount system to /system_root via
/dev/block/ symlinks, like AnyKernel and OpenGapps

- pass addon.d arguments through trampoline or nothing will happen
- exit immediately after handing over from trampoline
- better grep for recovery OUTFD which should work in all cases
- output to logcat when booted and no binaries are found
- use /postinstall/tmp path to call functions from addon.d-v2 in progress
- remove unnecessary check for $MAGISKBIN since we're already executing from within it
- make sure we're not in $TMPDIR again before we delete it
- use $MAGISKBIN wherever possible in case it ever needs to be changed
- adjust mount scripts to support SOS, APP and CAC Tegra partition naming (vendor is still vendor, oddly)
- -Xnodex2oat is removed on Android 10 in AOSP (despite it still erroneously showing in dalvikvm --help); older devices will still run safely without it
- Android 10 dynamically linked binaries need APEX mounts and variables so add this to recovery_actions/cleanup (thanks @Zackptg5)
- clean up known systemless root leftovers because we're helpful
- Update backup format as we might be patching multiple partitions
- Update uninstaller to remove files in persist (sepolicy.rule)
- Better handling for dtb/dtbo partition patching
