I recently upgraded my main workstation to Fedora 28, and I've been
unable to build ceph under it. It looks like the main problem is new
compiler warnings that have cropped up, and the fact that DPDK builds
with -Werror:
Here's one that looks like an actual bug, fwiw:
/home/jlayton/git/ceph-build/src/spdk/dpdk/lib/librte_metrics/rte_metrics.c: In function ‘rte_metrics_get_names’:
/home/jlayton/git/ceph-build/src/spdk/dpdk/lib/librte_metrics/rte_metrics.c:247:4: error: ‘strncpy’ specified bound 64 equals destination size [-Werror=stringop-truncation]
strncpy(names[idx_name].name,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
stats->metadata[idx_name].name,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
RTE_METRICS_MAX_NAME_LEN);
~~~~~~~~~~~~~~~~~~~~~~~~~
names[X].name is only RTE_METRICS_MAX_NAME_LEN bytes, so this can
overflow. Do we need a newer dpdk submodule?
