The last link suggests this issue is actually a bug -in rpcbind, which led me here. - -The leak caused by the reproducer at [4] appears to come from -rpcb_service_4(), in the case where svc_getargs() returns false and the -function had an early return, rather than passing through the cleanup -path at done:, as would otherwise occur. - -It also addresses a couple of other locations where the same fault seems -to exist, though I haven't been able to exercise those. I hope someone -more intimate with rpc(3) can confirm my understanding is correct, and -that I haven't introduced any new bugs. - -Without this patch, using the reproducer (and variants) repeatedly -against rpcbind with a numBytes argument of 1_000_000_000, /proc/$(pidof -rpcbind)/status reports VmSize increase of 976564 kB each call, and -VmRSS increase of around 260 kB every 33 calls - the specific numbers -are probably an artifact of my rhel/glibc version.
