[meta-oe][PATCH v1] image_types_sparse: switch ext* conversion to ext2simg_android

Ashish Kumar Mishra
2026-03-20T07:41:41Z

We have RFC discussion at
https://lists.openembedded.org/g/openembedded-devel/message/124499

Move ext* sparse image generation from 'img2simg' to ' ext2simg_android'
Summary of changes:
- android-tools: Export libsparse/libbase/liblog headers and libs to
sysroot to allow external linking. Masked v5.1.1.

- image_types_sparse.bbclass: Update CONVERSION_CMD to use ext2simg_android
for ext* types

- layer.conf: Sync BBMASK and add dynamic-layer paths.

- Add a custom do_compile step to build the ext2simg_android utility (ext2simg)
when building for the native class.

- Added 'image_types_sparse' to IMAGE_CLASSES and enabled 'ext4.sparse'
in IMAGE_FSTYPES.
This allows the build system to generate Android-style sparse image

- Switch to using $ORIGIN/../${baselib}.
$ORIGIN is a special variable recognized by the dynamic linker that represents
the directory containing the executable.

+
+Fixed:
+$ dd if=/dev/zero of=../image.ext4 bs=1M count=4k
+$ dd if=/dev/random of=../rootfs/largefile bs=1M count=3k
+$ ./misc/mke2fs -t ext4 -d ../rootfs/ ../image.ext4
+__populate_fs: Ext2 file too big while writing file "largefile"
+mke2fs: Ext2 file too big while populating file system
+
+This was because the offset is overflow, use __u64 to fix the problem.
+
+Another code which uses ext2_off_t is copy_fs_verity_data(), but it only copies
+the metadata, so it should be enough large for it, just leave it there.
