- fix naming BootSignature_Android.jar -> boot_signer-dexed.jar for my own builds (see https://issuetracker.google.com/issues/143810860)
- correct unpackbootimg/unpackelf suffixes which now correspond to their matching mkbootimg argument

- fix lzop detection use-case of magiskboot decompress which was broken in the generic stream refactor
|
|
- fix case where TWRP has /system_root mountpoint but ROM is non-SAR
- fix regression in ui_print when final character is \

addon.d-v2 support
- for A/B OTAs my FlashAfterUpdate addon.d script requires the zip to know about addon.d-v2 and act accordingly
- signify support with #FLASHAFTERUPDATEV2 tag in updater-script to pass whitelist check since the majority of zips will not work correctly

- with do.systemless prop enabled in anykernel.sh, will push the contents of modules/ to create a simple "ak3-helper" Magisk module, where testing on devices thus far shows it loads early enough that even replacement kernel object .ko modules will get loaded
- the ak3-helper module info is populated from the kernel.string and parsed kernel version from the kernel being flashed, and if at boot time a different kernel is detected the module automatically removes itself before being loaded to avoid conflicts
- since logical partitions and ext4-dedup on Android 10 now prevent mounting /system or /vendor rw under any circumstances, this feature gives kernel developers back the freedom they had before all this to improve kernel .ko modules, .conf files, etc. with the added bonus of it cleaning up after itself

- only repatch when there is an Image* (i.e. don't attempt on ramdisk-only mods)
- make sure new ramdisk is already copied before trying to detect Magisk patch state in case it changed
- clean up Magisk patch state and exported variables immediately
|
|
|
|
|
|
- also check patch status as part of repack_ramdisk() to avoid any issues if developer is forcing a compression format change
- get full Magisk patch status value and extract Magisk config to export correct environment variables for dtb patching

Compiled from my own updated fork:

- `test -e` could fail due to unexpanded *'s in $target
|
|
|
|
- running reset_ak before an unpack would remove any included ramdisk files from zip, so only remove if $split_img is detected suggesting an unpack has already occurred

- clean up magiskboot compression type output parsing
|
|
- resolves https://github.com/osm0sis/AnyKernel3/commit/698682123053cab9e3277c9c9df783a97b3e8958 "IMPORTANT NOTE" 1

- resolves https://github.com/osm0sis/AnyKernel3/commit/698682123053cab9e3277c9c9df783a97b3e8958 "IMPORTANT NOTE" 2, and allows 1 to be supported (via script change in subsequent commit)

Thanks @Zackptg5
Closes #40
|
|
- since magiskboot has built-in detection for the ChromeOS image pre-header signature, allow it to be auto-detected and if futility and signing files are present re-sign automatically (thanks @Zackptg5 for the nudge)
- simplify signing and error catching
- fix typo breaking ramdisk_recovery partition detection
- hide expected stderr for formats where some files may not exist (cmdline for ELF, etc.)
|
|
|
|
- previously this was failing a bit too spectacularly for my liking since $comp would erroneously get set to "fopen: ramdisk.cpio failed with 2: No such file or directory"
- on devices where there is no ramdisk.cpio unless rooted with Magisk this will indicate better to developers working on the device that they should be using "OG AK" mode to avoid trying to unpack a ramdisk which may or may not exist
|
|
|
|
- simplify rdtmp and $ramdisk creation and keep only in `unpack_ramdisk`
- fix `reset_ak` and `setup_ak` behavior if run before $block is set
- only save boot.img and boot-new.img in *-files subdirectories on multi-partition setups since otherwise the tmpfs (in recovery) and ext4 .img (when booted) size usage gets quickly out of hand
- fix slot_select=inactive when used with block=auto or block=boot partition detection

(note these probably require nanddump and nandwrite to access correctly)
|
|
- the expected "cat: write error: No space left on device" gives a non-zero return code so always return true
- devices that flash dtbo abort since the return code would get passed back to the Backend and silently fail as the final command in anykernel.sh (via `write_boot`), so catch seperately with a proper error message for other image write methods
|
|
- some device recoveries (e.g. TWRP for wahoo) seem to have issues with the new `cat <image> /dev/zero > <block>` method of flashing, so allow setting customdd="bs=1048576" shell variable in anykernel.sh to work around this by reverting back to dd wipe+flash for dtbo as it does with boot

- abstract out execution directory as $home to fascilitate testing individual scripts (defaults to /tmp/anykernel)
- general script clean ups for uniformity, readability, speed and simplicity
- simplify consecutive `ui_print` commands where possible
Backend only fixes:
- use busybox umount and mount whenever possible to avoid linker warnings in stderr during system-as-root setup
- use `busybox --install -s` for bin/* setup
- consolidate setup to abort earlier if there are issues
- add backwards compatible symlinks for those who might not have updated their anykernel.sh with ak3-core.sh (to be renamed in subsequent commit)
Tools only fixes:
- add magiskboot to replace separate support for AOSP and PXA-AOSP formats, with MTK headers, BLOB, DHTB, SEAndroid and Nook signing
- add magiskpolicy to allow for easy sepolicy patching
- remove xz and lz4 since magiskboot supports these
AK3 Core only fixes:
- use full `ui_print` function implementation like the backend
- add `abort` function to simplify exit on errors
- fix $patch directory being excluded from `reset_ak`
- update $ramdisk_compression handling for magiskboot
- magiskboot also resolves long-standing request for built-in Bump support (#18)
- update Sony ELF and related support for initial repack as AOSP by using mkbootimg as plug-and-play optional add-in binary
- update Sony ELF MTK header support using mkmtkhdr only when ELF is initially unpacked by unpackelf
- add support for MTK RECOVERY ramdisk header type with Sony ELF
- simplify U-Boot dumpimage/mkimage and Sony ELF unpackelf/mkbootimg split_img file handling
- update patch_cmdline to handle both magiskboot as header prop file, and unpackelf or mboot as cmdline.txt
- use `cp -fp` for `backup_file` and `restore_file` to hopefully better preserve attributes if used outside of the ramdisk
- refactor setup into `setup_ak` to simplify `reset_ak` trigger to find slot and block again
- add fallback to busybox for compression formats (i.e. lzop) which magiskboot cannot handle
IMPORTANT NOTES:
1) forcing repack with uncompressed cpio ramdisk is not currently supported by magiskboot
2) forcing repack with lzop ramdisk when previously another format is not currently supported by magiskboot

|
|
- extend `reset_ak` with `reset_ak keep` which will keep files to be available to patch the other slot
- add optional slot_select=inactive shell variable to force inactive slot during slot detection
|
|
|
|
- add built-in support for mboot for Intel OSIP devices (see: https://github.com/osm0sis/mboot)
