Subject: [pve-devel] [PATCH guest-common 1/1] storage tunnel: check just-imported image files
Date: Fri,  9 Aug 2024 13:22:32 +0200	[thread overview]
Message-ID: <20240809112234.1572295-2-f.gruenbichler@proxmox.com> (raw)
In-Reply-To: <20240809112234.1572295-1-f.gruenbichler@proxmox.com>

remote migration requires elevated privileges already and can thus only be
triggered by trusted sources, but an additional safeguard of checking the image
for external references doesn't hurt.

Notes:
    requires pve-storage change to actually have an effect
