Package: targetcli-fb
Version: 3.0.2-2
Severity: normal
Package: targetcli-fb
Version: 1:3.0.2-2
Severity: normal
Tags: patch
Dear Maintainer,
On Debian testing, targetcli-fb is unable to create a block backstore.
The "create" command under /backstores/block always fails because
targetcli passes the keyword argument "exclusive" to
rtslib_fb.BlockStorageObject(), but the installed class constructor does
not accept this argument.
This makes a central targetcli-fb operation unusable without locally
modifying a file installed by the package.
Steps to reproduce
==================
Create a block backstore using a valid unused block device:
/backstores/block> create name=vol0
dev=/dev/disk/by-id/nvme-QEMU_NVMe_Ctrl_feedcafe09452f116c49
Actual result
=============
targetcli aborts with the following traceback:
Traceback (most recent call last):

so = BlockStorageObject(name, dev, readonly=readonly, wwn=wwn,

TypeError: BlockStorageObject.__init__() got an unexpected keyword argument
'exclusive'
Cause
=====
The installed targetcli code calls:
so = BlockStorageObject(name, dev, readonly=readonly, wwn=wwn,
exclusive=exclusive)
However, the installed rtslib_fb.BlockStorageObject constructor does not
accept the "exclusive" keyword argument.
Package versions
================

python3-configshell-fb 1:2.0.3-1 all
python3-rtslib-fb 2.2.3-5 all
targetcli-fb 1:3.0.2-2 all
The constructor signature can be checked with:
python3 -c 'from rtslib_fb import BlockStorageObject; import inspect;
print(inspect.signature(BlockStorageObject))'

Proposed patch

creation to succeed:
