In case of mgmt cmds, task->hdr is dereferenced after transmitting the pdu in iscsi_tcp_task_xmit(). To handle this case current code increments the Tx skb reference count and frees the skb in cxgbi_cleanup_task(). In some error cases this results in skb leak. To fix this in case of mgmt cmds, allocate a separate buffer for iSCSI hdr and free this buffer in cxgbi_cleanup_task(). Signed-off-by: Varun Prakash <varun@chelsio.com> Signed-off-by: Martin K.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
