On receiving text request iscsi-target allocates buffer for payload in iscsit_handle_text_cmd() and assigns buffer pointer to cmd->text_in_ptr, this buffer is currently freed in iscsit_release_cmd(), if iscsi-target sets 'C' bit in text response then it will receive another text request from the initiator with ttt != 0xffffffff in this case iscsi-target will find cmd using itt and call iscsit_setup_text_cmd() which will set cmd->text_in_ptr to NULL without freeing previously allocated buffer. This patch fixes this issue by calling kfree(cmd->text_in_ptr) in iscsit_setup_text_cmd() before assigning NULL to it. For the first text request cmd->text_in_ptr is NULL as cmd is memset to 0 in iscsit_allocate_cmd().
