Subject: Error ret=-1 with EINTR in nbd_connect_systemd_socket_activation()
Date: Mon, 11 Jul 2022 06:38:14 +0000	[thread overview]
Message-ID: <DM6PR15MB2635A63B1B5F9F204E08BBEED5879@DM6PR15MB2635.namprd15.prod.outlook.com> (raw)

Hi, I'd like to connect to an encrypted QCOW2 file by nbd_connect_systemd_socket_activation(), but I got ret=-1 with EINTR.
The arg parameter I used is
qemu-nbd --object secret,id=sec0,data=abc123 --image-opts driver=qcow2,encrypt.format=luks,encrypt.key-secret=sec0,file.filename=/tmp/empty.qcow2

Can you find what a problem is? The version of qemu-nbd is
$ qemu-nbd -V
qemu-nbd 4.2.1 (Debian 1:4.2-3ubuntu6.23)

I created this encrypted QCOW2 image by the following command.
qemu-img create --object secret,id=sec0,data=abc123 -f qcow2 -o encrypt.format=luks,encrypt.key-secret=sec0 /tmp/empty.qcow2 8539292672

Note that I can connect to a normal QCOW2 file by this function without any error. (arg: qemu-nbd -f qcow2 /tmp/normal.qcow2)
