From 7ba41963dde175581ae7b395045fd51678237930 Mon Sep 17 00:00:00 2001 From: Christian Hesse Date: Thu, 7 Jun 2018 21:31:28 +0200 Subject: snapshot: support tar signature for compressed tar This adds support for kernel.org style signatures where the uncompressed tar archive is signed and compressed later. The signature is valid for all tar* snapshots. We have a filter which snapshots may be generated and downloaded. This has to allow tar signatures now even if tar itself is not allowed. To simplify things we allow all signatures.
