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().

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.
