This issue crossed file boundaries. It was a bit tricky, since
vethCreate was used in two patterns - one where the parent name was
already known, and another where the parent name is picked as the
first available option. But the end result avoids strdup'ing a
fixed-width buffer, and I think I correctly avoided any leaks (in
lxcSetupInterfaces, once a string is transferred to *veths, then
returning failure will cause that string to be freed in the caller).
It also gets rid of a PATH_MAX stack over-allocation.
Looks good, ACK.
Thanks; pushed.
