Alexei Starovoitov 19e2dbb7dd bpf: improve stacksafe state comparison ... "if (old->allocated_stack > cur->allocated_stack)" check is too conservative. In some cases explored stack could have allocated more space, but that stack space was not live. The test case improves from 19 to 15 processed insns and improvement on real programs is significant as well: before after bpf_lb-DLB_L3.o 1940 1831 bpf_lb-DLB_L4.o 3089 3029 bpf_lb-DUNKNOWN.o 1065 1064 bpf_lxc-DDROP_ALL.o 28052 26309 bpf_lxc-DUNKNOWN.o 35487 33517 bpf_netdev.o 10864 9713 bpf_overlay.o 6643 6184 bpf_lcx_jit.o 38437 37335 Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Edward Cree <ecree@solarflare.com> Acked-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>		2018-12-15 01:28:32 +01:00
