Subject: [pbs-devel] [PATCH proxmox-backup 2/3] Userid: fix borrow/deref recursion
Date: Thu, 8 Oct 2020 15:37:19 +0200 [thread overview]
Message-ID: <20201008133720.2894310-2-f.gruenbichler@proxmox.com> (raw)
In-Reply-To: <20201008133720.2894310-1-f.gruenbichler@proxmox.com>
not triggered by any current code, but this would lead to a stack
exhaustion since borrow would call deref which would call borrow again..
