Started using valgrind with DPDK, and there are lots of leftover memory and file descriptors. This makes it hard to find application leaks versus DPDK leaks.
The DPDK has a function that applications can use to tell it to cleanup resources on shutdown (rte_eal_cleanup). But the current coverage of that API is spotty. Many internal parts of DPDK leave files and allocated memory behind. This patch set is a first step at getting the sub-parts of DPDK to cleanup after themselves. These are the easier ones, the harder and more critical ones are in the drivers and the memory subsystem. There are no new exposed API or ABI changes here. v2 - rebase after 20.05 file renames - incorporate review comment feedback - hold off some of the more involved patches for later Stephen Hemminger (8): eal: log: close on cleanup eal: log: free dynamic state on cleanup eal: alarm: close file on cleanup eal: cleanup threads eal: mp: end the multiprocess thread during cleanup eal: vfio: cleanup the mp sync handle eal: hotplug: cleanup multiprocess resources eal: malloc: cleanup mp resources lib/librte_eal/common/eal_common_log.c | 33 ++++++++++++++++++++++++- lib/librte_eal/common/eal_common_proc.c | 17 +++++++++---- lib/librte_eal/common/eal_private.h | 20 +++++++++++++++ lib/librte_eal/common/hotplug_mp.c | 5 ++++ lib/librte_eal/common/hotplug_mp.h | 6 +++++ lib/librte_eal/common/malloc_heap.c | 6 +++++ lib/librte_eal/common/malloc_heap.h | 3 +++ lib/librte_eal/common/malloc_mp.c | 12 +++++++++ lib/librte_eal/common/malloc_mp.h | 3 +++ lib/librte_eal/freebsd/eal.c | 1 + lib/librte_eal/freebsd/eal_alarm.c | 10 ++++++++ lib/librte_eal/linux/eal.c | 20 +++++++++++++++ lib/librte_eal/linux/eal_alarm.c | 11 +++++++++ lib/librte_eal/linux/eal_log.c | 14 +++++++++++ lib/librte_eal/linux/eal_vfio.h | 1 + lib/librte_eal/linux/eal_vfio_mp_sync.c | 8 ++++++ 16 files changed, 164 insertions(+), 6 deletions(-) -- 2.20.1
