#64242 — Bug#930366: initramfs-tools: unmkinitramfs fails to unpack lz4 compressed initrd

[Multipart message — attachments visible in raw view] — view raw

Package: initramfs-tools
Version: 0.133
Severity: normal
Tags: patch

Dear Maintainer,

unmkinitramfs fails to unpack lz4 compressed initrd, ie.:

$ sudo apt install initramfs-tools lz4 file
$ mkinitramfs -c lz4 -o foo.img
$ unmkinitramfs foo.img bar
cpio: premature end of archive
$ echo $?
2

I think this is because lz4cat is strict with file extensions:

$ file foo.img 
foo.img: LZ4 compressed data (v0.1-v0.9)
$ lz4cat -t foo.img 
File extension doesn't match expected LZ4_EXTENSION (.lz4); will not process file: foo.img

I propose the attached patch to change 'lz4cat -t $archive'
invocations to become 'lz4cat -t <$archive' instead. As lz4cat does
not / cannot enforce extension checking on streams.

Regards,

Dimitri.
