Hi Martin,
The patch series contains fixes for qla2xxx and solves two visible
issues:
- Target port in N2N topology doesn't perform login if it has higher
WWPN than initiator
- ABORT TASK TMF leads to crash if it's received shortly after ACL of
an initiator is deleted and there's active I/O from the initiator
It also contains reliability improvements and cleanups.
Unfortunately, there's still an issue the latest patch. The discard
works but ELS IOCB for LOGO is likely built incorrectly by
qla24xx_els_dcmd_iocb(). The issue can also be exposed when "1" is
written to fc_host/hostN/device/issue_logo file with logging turned on.
Changes since v1 (https://patchwork.kernel.org/cover/11141979/):
- Fixes target port in N2N mode were added (patches 5-11);
- Target port makes explicit LOGO on session teardown in the patch made
by Quinn. Together with patch 1, it helps to immediately turn
fc_remote_port to the Blocked stated on client side and avoids visibly
stuck session;
- The last three patches address violation of FCP specification with
regards to handling of ABTS-LS from ports that are not currently
logged in.
Thank you,
Roman
