From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Hi folks,
Here are three outstanding target bug-fixes encountered during
failure and longevity testing with v4.1.y code.
The patch #1 is a v4.1+ regression where the missing upstream
assignment of SCF_ACK_KREF results in se_cmd->cmd_kref leakage
during TMR ABORT_TASK + LUN_RESET with concurrent session
reinstatement. v4.0 and earlier code is not effected.
The latter two address long-standing EXTENDED_COPY status bugs,
that can result in ESX hosts failing VAAI BlockCopy operations.
Patch #2 adds COPY TARGET DEVICE NOT REACHABLE during 0xe4
target descriptor NAA IEEE 0x83 /sys/kernel/config/target/core/
device lookup failure, in order to signal local copy fallback
to host.
Patch #3 propigates up correct local copy I/O SCSI status
(eg: RESERVATION_CONFLICT) to host.
Please review.
