The memory leak bug up to 3.6.14 was only related to ccm, but gcm was fine. This avoids talloc+memcpy on more systems, e.g. ubuntu 20.04, and brings ~ 20% less cpu overhead, see: https://hackmd.io/@asn/samba_crypto_benchmarks BUG: https://bugzilla.samba.org/show_bug.cgi?id=14764 Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Andreas Schneider <asn@samba.org>
