open-iscsi 2.1.0 broken with CHAP md5
The CHAP support in 2.1.0 does not work with CHAP md5, used by for instance tgtd and Synology.
This was fixed in 2.1.1 with the following PR: https://github.com/open-iscsi/open-iscsi/pull/182
Upstream issue: https://github.com/open-iscsi/open-iscsi/issues/180
Please backport 2.1.2 from edge to v3.12 and v3.11 (where 2.1.0 was introduced)
