[dm-devel] [PATCH] libmultipath: fix memory leak in reconfigure

[tang.junhui at zte.com.cn]

Problem:

 * Memory leak exists in reconfigure function when multipathd command 
"reconfigure" is executed.

Reasons:

 * The following judgement condition is not satisfied when there is no 
path , free_pathvec is not called to free the vector of vecs->pathvec:
        if (VECTOR_SIZE(vecs->pathvec))
                free_pathvec(vecs->pathvec, FREE_PATHS);

 * Then the vecs->pathvec is set to NULL, so the vector memory which 
vecs->pathvec pointed to is leaked:
        vecs->pathvec = NULL;


Please review the solutions to the problem in the attachment:
