[SCSI] iscsi_transport: Add support to display CHAP list and delete CHAP entry

2012-02-29T22:55:59+00:00

This patch adds support to list CHAP entries stored in FLASH and
delete specified CHAP entry from FLASH using iscsi tools.

[SCSI] iscsi class: export pid of process that created

2011-12-15T06:57:40+00:00

There could be multiple userspace entities creating/destroying/
recoverying sessions and also the kernel's iscsi drivers could
be doing this too. If the userspace apps do try to manage the kernel
ones it can get the driver/fw out of sync and cause the user to
loose the root disk, oopses or ping ponging becasue userspace
wants to do one thing but the kernel manager thought we
are trying to do another.

This patch fixes the problem by just exporting the pid of
the entity that created the session. Userspace programs like
iscsid, iscsiadm, iscsistart, qlogic's tools, etc, can then
figure out which sessions they own and only manage them.

[SCSI] qla4xxx: fix data alignment and use nl helpers

2011-10-20T15:12:44+00:00

This has the driver use helpers for a common operation and fixes
a issue where if multiple iscsi params are sent they could be
sent at offsets that cause unaligned accesses. The nla helpers
account for the padding needed to align properly for the driver.

[SCSI] scsi_transport_iscsi: Add conn login, kernel to user, event to support offload session login.

2011-08-27T14:36:23+00:00

Offload drivers like qla4xxx will offload the sending of the login/logout
pdus still, so this patch adds iscsi_conn_login_event which is
used by these types of drivers to notify userspace that the connection
has changed state.

It also adds a iscsi_is_session_online helper so the lld
can query the sessions state field.
