cache_lock: do xstrdup/free on lockfile
Since fmt() uses 8 alternating static buffers, and cache_lock might call cache_create_dirs() multiple times, which in turn might call fmt() twice, after four iterations lockfile would be overwritten by a cachedirectory path. In worst case, this could cause the cachedirectory to be unlinked and replaced by a cachefile. Fix: use xstrdup() on the result from fmt() before assigning to lockfile, and call free(lockfile) before exit. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
