2011-12-15[SCSI] qla4xxx: Perform context resets in case of context failures.Vikas Chaudhary
For 4032, context reset was the same as chip reset, and any firmware issue was recovered by performing a chip reset. For 82xx, the iSCSI firmware runs along with FCoE and the NIC firmware contexts, and an error encountered doesnot essentially mean that a chip reset is necessary. Perform Chip resets only in the following cases: 1. Mailbox system error. 2. Mailbox command timeout. 3. fw_heartbeat_counter counter stops incrementing. For all other cases, only perform a context reset. 1. Command Completion with an invalid srb. 2. Other mailbox failures.

Udev uses the connection's persistent address/port in the /dev/disk/by-path name. qla4xxx is not exporting this value so its iscsi disk names have been lacking the iscsi info.

2011-10-16[SCSI] qla4xxx: Do not add duplicate CHAP entry in FLASHLalit Chandivade
QLogic applications store the CHAP information in FLASH. During login, authentication information is provided using an index into the CHAP region. In order to support QLogic applications along with iscsiadm, updated the LLD to not add duplicate CHAP entries in the CHAP region and preserve the existing CHAP info in the CHAP region in FLASH. This allows QLogic applications to pre-write the CHAP entries in the CHAP region. With iscsiadm, when the CHAP authentication information is sent to the LLD, the LLD searches for the entry in CHAP region in FLASH, if exists then do not add. If CHAP entry does not exist then add the CHAP entry in the CHAP region.

2011-08-27[SCSI] qla4xxx: Remove reduandant code after open-iscsi integration.Manish Rangankar
1. Remove device database entry (ddb) state. 2. Remove device database (DDB) list building. With open-iscsi integration the logins to the target devices are handled by the user space. So the information of target is now maintained in the iscsi_session object. This is handled at libiscsi level so there is no need to maintain a list of DDBs in the qla4xxx LLD. 3. qla4xxx: Remove add_device_dynamically. Since autologin in FW is disabled with open-iscsi integration, driver will never get an AEN for which driver has not requested a DDB index. So remove the add_device_dynamically function. 4. Remove qla4xxx_tgt_dscvr Since firmware autologin is disabled this function will not work. Now user has the ability to do the target discovery and login to each target individually. Firwmare will not do the login on its own. 5. Remove relogin related code All relogin is handled by userspace now. qla4xxx just need to notify userspace of a connection failure, this triggers the relogin. 6. Remove add_session and alloc_session Now qla4xxx uses iscsi_session_setup that would do the necessary allocations for session and ddb_entry.
