Subject: [PATCH] iscsid: fix iscsid segfault during qla4xxx login

If the kernel sends multiple ISCSI_KEVENT_CONN_LOGIN_STATE
events for the same login event iscsid will segault.

When we get a conn error we will set the r_stage to reopen, then when
session_conn_process_login handles the first login event we set the r_stage
to R_STAGE_NO_CHANGE. But then it looks like if we get a second login event
r_stage is no_change and session_conn_process_login will run again and
call mgmt_ipc_write_rsp on a bad qtask.

Subject: [PATCH] ISCSISTART: Bring up the corresponding network interface for iboot

This is needed for the iSCSI offload boot.

Snip from M. Christie:
Note that we must bring up the interface before iface_setup_from_boot_context,
because we will want iscsi_sysfs_get_host_no_from_hwaddress to be able to match
a MAC to a iscsi host.  For some bnx2i cards, the card has to be ifupd for the
iscsi interface to have a MAC. If it is not ifupd we have seen MACs with all
zeros or no iscsi_hosts on different cards.

Subject: [PATCH] iscsi tools: Convert '-r' argument to an integer before checking if it is a path

If there is a file in the CWD named '1' and you were trying to run
'iscsiadm -m session -r 1 ...', the command would fail with "1 is not a
directory".

Root cause: The code that parses the -r option's argument tries lstat(2)
first, falling back to atoi(3) only if lstat fails.

This change inverts the order of checks, first with strtol(3) to see if
the argument given is a positive integer, then falling back to lstat(2)
only if it is not.

 5. Open-iSCSI Configuration Utility
 ===================================
 
-Open-iSCSI persistent configuration is implemented as a DBM database
-available on all Linux installations.
-
-The database contains two tables:
-
-- Discovery table (/etc/iscsi/send_targets);
-- Node table (/etc/iscsi/nodes).
-
-The regular place for iSCSI database files: /etc/iscsi/nodes
+Open-iSCSI persistent configuration is stored in a number of
+directories under a configuration root directory, using a flat-file
+format. This configuration root directory is /etc/iscsi by default,
+but may also commonly be in /var/lib/iscsi.
+
+Configuration is contained in directories for:
+
+- nodes
+- slp
+- isns
+- static
+- fw
+- send_targets
+- ifaces
 
 The iscsiadm utility is a command-line tool to manage (update, delete,
 insert, query) the persistent database.
