Subject: [PATCH] Fix regression reading rpm v3 and other rare packages (#1635)
a5e32e
a5e32e
Commit d6a86b5e69e46cc283b1e06c92343319beb42e21 introduced far stricter
a5e32e
checks on what tags are allowed in signature and main headers than rpm
a5e32e
had previously seen, and unsurprisingly this introduced some regressions
a5e32e
on less common cases:
a5e32e
a5e32e
- On rpm v3 packages and some newer 3rd party created packages (such as
a5e32e
  install4j < 9.0.2), RPMTAG_ARCHIVESIZE resides in the main header
a5e32e
  to begin with
a5e32e
- In rpm 4.13 - 4.14, file IMA signatures were incorrectly placed in
a5e32e
  the main header.
a5e32e
a5e32e
As a quirk, permit the existence of RPMTAG_ARCHIVESIZE,
a5e32e
RPMTAG_FILESIGNATURES and RPMTAG_FILESIGNATURELENGTH in the main header
a5e32e
too provided that the corresponding signature tag is not there (so
a5e32e
they can reside in either but not both headers).
a5e32e
a5e32e
Initial workaround patch by Demi Marie Obenour.

Fixes: #1635
a5e32e
a5e32e
Backported for 4.16.1.3.
