so what grub is doing is correct. It pads/aligns every initrd by 4, which is fine, and as per spec.
https://www.kernel.org/doc/html/latest/driver-api/early-userspace /buffer-format.html initramfs size can be filled with arbitrary amount of "\0" all the way upto initramfs_size. "In human terms, the initramfs buffer contains a collection of compressed and/or uncompressed cpio archives (in the “newc” or “crc” formats); arbitrary amounts zero bytes (for padding) can be added between members." Thus it feels to me that decompress_unlz4.c method in the kernel does not correctly stop decompressing and returning consumed output position (posp). For example, decompress_inflate.c skips over trailer and updates output pos by 8, at the end of successful conversion. Similarly unlzma also updates posp at the end of conversion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1835660/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
