The intended behavior of function ipmi_hardcode_init_one() is to default to kcs interface when no type argument is presented when initializing ipmi with hard coded addresses. However, the array of char pointers allocated on the stack by function ipmi_hardcode_init() was not inited to zeroes, so it contained stack debris. Consequently, passing the cruft stored in this array to function ipmi_hardcode_init_one() caused a crash when it was unable to detect that the char * being passed was nonsense and tried to access the address specified by the bogus pointer. The fix is simply to initialize the si_type array to zeroes, so if there were no type argument given to at the command line, function ipmi_hardcode_init_one() could properly default to the kcs interface.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
