Closed: Fixed
Reopen Issue

This was reported to me by @puiterwijk , who has worked around the issue here

https://github.com/fedora-iot/rpm-head-signing/pull/61/files

In rpm_hdr_size, Koji pads the header length to a multiple of 8 bytes. However, it seems that this is only appropriate to do for signature headers.

Fix forthcoming

The Maximum RPM book alludes to the padding thusly:
https://ftp.osuosl.org/pub/rpm/max-rpm/s1-rpm-file-format-rpm-file-format.html

There are four null bytes following the last data item in order to round the size out so that it ends on an 8-byte boundary.

The rpm.org docs say:
https://rpm-software-management.github.io/rpm/manual/format.html

the Signature section is padded to a multiple of 8 bytes

Neither indicates similar padding for the main header
