2014-07-13	Set KERN_PROC_NOBROADCASTKILL so that iscsid is not killed by init	Claudio Jeker
	when terminating multi-user so that we have a chance to sync the file systems mounted via iscsi.
2014-05-10	Extend the connection and session FSMs so that connection failure is	Claudio Jeker
	handled more gracefully. Losing the TCP connection no longer results in an unrecoverable stop requiring a restart of iscsid.
2014-05-10	Move the task cleanup from the task fail callback to taskq_cleanup.	Claudio Jeker
	This makes the one failure callback a lot simpler.
2014-04-21	Bind to localAddr if specified and add some XXX comments about stuff	Claudio Jeker
	that is not prefect yet.
2014-04-21	Start passing the initiator and target name in the show command.	Claudio Jeker

2014-04-21	Redo most of the control message handling. Switch it back to use	Claudio Jeker
	SOCK_SEQPACKET and provide functions to build the control messages that can also be used by iscsictl.
2014-04-21	Handle EAGAIN, ENOBUFS and EINTR a bit better. Ignore them one layer above	Claudio Jeker
	and do not fail and tear down the world when they happen.
2014-04-21	It is possible that we can't burst all of the data in the immediate data	Claudio Jeker
	part of the write request. In that case R2T requests with be sent for the rest of the data. The amount of data we can send is defined by MaxRecvDataSegmentLength which is per connection and so a bit hackish to read out. In the long run the min() of all connection MaxRecvDataSegmentLength should be stored in the session struct.
2014-04-21	Now that we properly negotiate the session params we can enable sending	Claudio Jeker
	of immediate data for write commands. This gives a nice 20% performance boost on writes compared to the solicited data transaction we did before.
2014-04-20	Introduce some basic stats for the vscsi layer. Just counting the commands	Claudio Jeker
	and the bytes we push through vscsi(4).
2014-04-20	After doing all of the loging dance to get the target's params it makes	Claudio Jeker
	sense to merge them into the active set. At least that way we run with the right params and finally do reads and writes that are > 8k.
2014-04-20	Use only one style for "return foo;"	Claudio Jeker

2014-04-20	Move session params initialization to when we start a session and not	Claudio Jeker
	when it is created. That way the config params from the config file have a chance to stick.
2014-04-20	Fix conn_gen_kvp and its caller to fill the kvp array properly (including	Claudio Jeker
	the NULL terminator at the end). Now iscsid does proper LoginOperational negotiation (which will bump the MaxRecvDataSegmentLength to 64k)
2014-04-20	Cleanup a bit, switch on bcopy to memcpy and move a function a bit up	Claudio Jeker

2014-04-19	COnveret the bcopy() to memcpy()	Claudio Jeker

2014-04-19	Replace a magic number.	Claudio Jeker

2014-04-07	To win the startup race on the control socket we need to listen to it as	Claudio Jeker
	well only then the connect() call from iscsictl will not fail. Move listen() into the init function and rename control_listen() to control_event_init() since it is now only doing that.
2014-02-17	Call control_init() before daemon() so that iscsid && iscsictl reload works	Claudio Jeker

2013-08-14	no longer any need to quote macro lines with >9 args;	Jason McIntyre
	From: Jan Stary
2013-07-16	use .Mt for email addresses; from Jan Stary <hans at stare dot cz>; ok jmc@	Ingo Schwarze

2013-03-11	handle ECONNABORTED errors from accept(). In many code blocks they can be	Theo de Raadt
	ignored silently and without aborting, much like EINTR and EWOULDBLOCK are. ok's from various maintainers of these directories...
2012-09-26	last stage of rfc changes, using consistent Rs/Re blocks, and moving the	Jason McIntyre
	references into a STANDARDS section;
2012-06-26	tweak previous;	Jason McIntyre

2012-06-26	There is a iscsi.conf man page now. Reminded by jmc@	Claudio Jeker

2012-04-11	accept() pacing on the control socket if E*FILE errors are returned.	Claudio Jeker
	Based on work by Theo for ospfd and friends. OK deraadt@
2011-08-20	Add support for -v (enable verbose logging on the command line).	Stuart Henderson
	Previously only available via iscsictl. ok claudio@
2011-05-04	Massive diff to handle logins more correctly. iscsid will now do	Claudio Jeker
	better operational parameter negotiation but more is needed. Tested by todd@ and myself.
2011-05-02	Rework the logout code and use this to do a proper logout when	Claudio Jeker
	exiting. This works well for idle sessions but still has some issues on busy session. It seems more task scheduler changes are needed to make this work. This also includes some mem-leak fixes in error pathes found by Igor Zinovik. go for it dlg@
2011-04-28	Try to schedule a new task for the connection in conn_task_cleanup()	Claudio Jeker
	this removes the session_schedule() in the task_pdu_cb().
2011-04-28	DATA OUT operations need to be piggibacked on the same connection as	Claudio Jeker
	the initial SCSI REQUEST so use conn_task_issue() in vscsi_dataout().
2011-04-27	Implement CTRL_LOG_VERBOSE to toggle log verbosity.	Claudio Jeker

2011-04-27	Rename task_cleanup() to conn_task_cleanup() seems a better place for	Claudio Jeker
	this function since it does connections scheduling.
2011-04-27	Add log_verbose() like all the other log.c users.	Claudio Jeker

2011-04-27	Start implementing the FSM. Introduce a session FSM that is run via a	Claudio Jeker
	callback and implement some of the connection FSM actions. Implement logouts so that discovery sessions do a nice login -> query -> logout. Fix the task scheduling especially for immediate and connection specific tasks. The session will now only schedule tasks to a session that is in LOGGED_IN state. looks good dlg@
2011-04-05	Move session related code into session.c.	Claudio Jeker

2011-04-05	Log the SessionName so that it is possible to understand which session	Claudio Jeker
	caused the problem.
2011-01-10	Remove 2 empty lines.	Claudio Jeker

2011-01-06	Ugly hack, call session_schedule in the task pdu callback handler.	Claudio Jeker
	Without this accessing both LU on my iscsi target will lock up because tasks a queued but no longer scheduled. We need a better task scheduler but this allows me to run iogen on both partitions without locking up.
2011-01-06	Pass the magic LUN -1 to VSCSI_REQPROBE so that all LU are probed	Claudio Jeker
	by the midlayer. With help from dlg@
2011-01-06	Add minimal LUN handling. Currently only single level LUN addressing is	Claudio Jeker
	supported because the vscsi ioctl interface is limited to that. Seems to work according to my iscsi target having 2 units per target. OK dlg@
2011-01-04	Implememnt NOP-IN -> NOP-OUT handling. If the NOP-In was issued by the	Claudio Jeker
	target (itt = 0xffffffff) send back an immediate NOP-Out reusing the NOP-In PDU. This makes my iscsi target happy. Also plug a mem leak on error path which was found by Igor Zinovik.
2011-01-04	Cleanup tasks with a NULL callback after queuing the PDU to be sent out.	Claudio Jeker
	This allows immediate responses (e.g. NOP-out) to be issued with a task instead of very special code. Also set expstatsn on all PDU that carry it.
2011-01-04	Reset the resid before issuing the task callback so that the pdu can	Claudio Jeker
	be reused for sending out a message. This will be used soon for NOP handling.
2011-01-04	Print itt, cmdsn and expstatsn as unsigned when printing a PDU.	Claudio Jeker

2011-01-04	Truncate the scsi sense data to 18 bytes if more data was supplied.	Claudio Jeker
	dlg@ said it is OK to do that since the additional data is optional. My connection to the iscsi target sending 64byte sense data is now much happier.
2011-01-04	When translating a PDU to text strip all trailing \0 but one.	Claudio Jeker
	Fixes parsing of login responses that had additional padding.
2011-01-04	Log the PDU which failed because no task was found.	Claudio Jeker
	Should help identify the messages that are issued by the target (e.g. NOP).
2011-01-04	Add missing session parameter.	Claudio Jeker

2010-09-25	spacing, no binary changes.	Igor Sobrado
