Subject: [pve-devel] [PATCH access-control 2/3] permissions: fix token/user priv intersection
Date: Fri,  3 Jun 2022 13:50:48 +0200	[thread overview]
Message-ID: <20220603115049.1908792-3-f.gruenbichler@proxmox.com> (raw)
In-Reply-To: <20220603115049.1908792-1-f.gruenbichler@proxmox.com>

the token/user priv intersection could only honored user privs that had
the propagation flag set, reducing the scope of the token more than
intended.

the pre-existing test case actually triggered the broken behaviour, but
the expected value matched it so it was not noticed.

Fixes: e8a0cee47bb477162f291e67144ea0c0df47f2ee "rpcenv: improve user/token intersection"
