Description Nilesh Javali (Marvell) 2019-08-01 05:42:40 UTC

Please update iscsiuio bug fix from the latest upstream,

https://github.com/open-iscsi/open-iscsi/pull/169 

Please consider the above fix for RHEL 8.1 Inbox.

Thanks.

Comment 1 Nilesh Javali (Marvell) 2019-08-19 10:11:09 UTC

We need z-stream packages for RHEL 8.0, RHEL 7.7, RHEL 7.6 with this fix for users who still want to use inbox iscsiuio package.

Comment 2 Chris Leech 2019-11-22 05:14:45 UTC

these changes are already in a package build after initial update for 8.2.0

Comment 4 Chris Leech 2020-01-27 18:49:57 UTC

This is the description of the issue that went along with the upstream change, which more directly calls out the impact on MPIO booting when one path might fail DHCP initilization.

Problem: OS fails to boot after one path is
        disconnected from iSCSI MPIO config.
Change: In the event of DHCP failure, killing of enable_nic_thread did
        not process any iscsid requests leading to error,
        iscsistart: Could not broadcast to uIP after 5 tries
        and login failure of active path.
        Added fix to not kill enable_nic_thread and allow further
        processing of iscsid requests and performing login
        to next active path.

Comment 5 Chris Leech 2020-01-27 18:52:33 UTC

This change is also currently in 7.8
related RHEL-7 BZ 1724579

Comment 6 Rob Evers 2020-01-27 18:55:25 UTC

Chris, Please provide justifcation for z-stream. Also indicate risk associated. Thanks

Comment 7 Chris Leech 2020-01-27 18:59:34 UTC

Due to possible issues with reboot stability when MPIO is supposed to be increasing availability, I think this is justified for 8.1.z

The change is rather minor, and isolated to the iscsiuio component which only impacts bnx2i and qedi iSCSI controllers.  I haven't seen any issues caused by it after adding to 8.2 and 7.8 already.

Comment 8 Rob Evers 2020-01-27 19:27:54 UTC

Not taking in z-stream due to capacity constraints and lack of direct customer request

Comment 9 Filip Suba 2020-03-19 08:15:47 UTC

Verified SanityOnly with iscsi-initiator-utils-6.2.0.878-3.gitd791ce0.el8. Regression testing passed.
