Subject: [Iscsitarget-devel] [PATCH]Safe task mgt function code
From: "Henry Liu" <henryliuhl@gmail.com>
Date: Tue, 18 Jul 2006 18:02:53 +0800

We all known that IET task management function is not safe. In my
test, I allways find kernel panic cuz LUN RESET or TARGET WARM RESET
though there is only low stress.
Below is my patch for fixed it. I have test LUN RESET and TARGET WARM
RESET but TARGET COLD RESET.

Subject: [Iscsitarget-devel] nr_busy_cmnds judge is not safe
From: "Henry Liu" <henryliuhl@gmail.com>
Date: Mon, 10 Jul 2006 12:21:59 +0800

Dears:
    I think atomic_inc(&cmnd->conn->nr_busy_cmnds); is not safe in
whtread.c get_ready_cmnd function.
    In nthread.c file static void close_conn(struct iscsi_conn *conn)
function have below instruments:
    while (atomic_read(&conn->nr_busy_cmnds))
                yield();

    But after judging nr_busy_cmnds is zero and before next delete
cmnds instruments, nr_busy_cmnds would be incremented by
get_ready_cmnd of wthread. So iscsi will has null operation.

isns_target_register() is called after insque a target to targets_list. So list_empty does not work.

Subject: [PATCH] fix handling of NOP-Out w/ unexpected ping data
From: Arne Redlich <agr@powerkom-dd.de>
Date: Mon, 03 Jul 2006 21:39:38 +0200

If an initiator sends a NOP-Out with a reserved ITT, we don't handle the
unlikely case of the PDU containing (needless) ping data correctly.

Problem pointed out by Henry Liu <henryliuhl@gmail.com>.

Subject: [Iscsitarget-devel] Drop dead sessions using KEEPALIVE socket option
From: "Richard Bollinger" <rabollinger@gmail.com>
Date: Mon, 3 Jul 2006 12:35:58 -0400

Attached is a patch to ietd.c which enables the KEEPALIVE socket
option, so that dead client connections go away.  Without something
like this, the defunct sessions seem to stay around forever after a
client crash.

Subject: [Iscsitarget-devel] [PATCH] fix IET fileio_sync() error handling
From: Arne Redlich <agr@powerkom-dd.de>
Cc: iscsitarget-devel@lists.sourceforge.net
Date: Sat, 01 Jul 2006 10:41:08 +0200

fileio_sync() currently ignores the return value of sync_page_range()
instead of propagating errors to the caller (and, finally, the
initiator). Fixed by the patch below (only compile tested).

In case of I/O errors, IET doesn't notify the initiator and instead
lets it believe the I/O operation succeeded.

Trivial patch to fix the mode sense response. We use write through in
IET so WCE bit should be 0.

This patch will change KERNELSRC to KERNELDIR because of KERNELSRC being 
used in the out-of-source-tree compile in linux (make O= option).
Using KERNELSRC will cause an endless make loop when compiling 
iscsi-target against such a setup becausde of this:
%::
        $(MAKE) -C $(KERNELSRC) O=$(KERNELOUTPUT) $@
being the top makefile in linux then.
