Multiple Connections LIO Target Failing in Initial Login Request

[Santosh Kulkarni <santosh.kulkarni@xxxxxxxxxxxxxx>]

Hi Nab,

Am trying to login through multiple connections in a Session. However 
after the login succeeds on the leading connection the subsequent 
connections in the session fail to succeed in the initial login requests 
and hence login fails on subsequent connections.

I looked into the code and i see that a kmalloc  for a "tmpbuf" fails 
for the initial login request processing.

Here's the dmesg.

[872129.660613] Unable to allocate memory for tmpbuf.
[872129.660619] iSCSI Login negotiation failed.

PFA the pcap for the entire login process.
I see the following issue with both my code for a Linux initiator and as 
well a Windows Standard Initiator.


Target Kernel:
# uname -r
3.14.0-rc6+

cat /sys/kernel/config/target/version
Target Engine Core ConfigFS Infrastructure v4.1.0 on Linux/x86_64 on 
3.14.0-rc6+


Am i looking at a possible issue.Please comment.

Regards
Santosh
