virFileMakePath is a recursive function that was creates a buffer PATH_MAX bytes long for each recursion (one recursion for each element in the path). This changes it to have no buffers on the stack, and to allocate just one buffer total, no matter how many elements are in the path. Because the modified algorithm requires a char* to be passed in rather than const char *, it is now 2 functions - a toplevel API function that remains identical in function, and a 2nd helper function called for the recursions, which 1) doesn't allocate anything, and 2) takes a char* arg, so it can modify the contents. * src/util/util.c: rewrite virFileMakePath
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
