memory issue in iser

[clicx]

in iser.c, line 333:
if (pdu->indata.size <= iscsi->smalloc_size) {

it should be if (pdu->indata.size >= iscsi->smalloc_size) {

This is a problem, but I think the real cause of the problem comes from the allocation.
In the current code, the allocation and free of iser_pdu->iscsi_pdu.indata.data mismatch.
