Serebryakov --- Steps to reproduce for me: (1) Two hosts: 192.168.134.1, 12-ALPHA7, slow, without AES-NI 192.168.134.2, 11-STABLE, fast, with AES-NI (2) Setup IPsec transport for TCP port 5201 (iperf3 part): (a) on 192.168.134.2 setkey -c<<__END flush; spdflush; add 192.168.134.1 192.168.134.2 esp 0x10001 -E rijndael-cbc "0123456789abcd= ef"; add 192.168.134.2 192.168.134.1 esp 0x10002 -E rijndael-cbc "0123456789abcd= ef"; spdadd 192.168.134.2/32[5201] 192.168.134.1/32 tcp -P out ipsec esp/transport//require; spdadd 192.168.134.1/32 192.168.134.2/32[5201] tcp -P in ipsec esp/transport//require; __END (b) on 192.168.134.1 setkey -c <<__END flush; spdflush; add 192.168.134.1 192.168.134.2 esp 0x10001 -E rijndael-cbc "0123456789abcd= ef"; add 192.168.134.2 192.168.134.1 esp 0x10002 -E rijndael-cbc "0123456789abcd= ef"; spdadd 192.168.134.1/32 192.168.134.2/32[5201] tcp -P out ipsec esp/transport//require; spdadd 192.168.134.2/32[5201] 192.168.134.1/32 tcp -P in ipsec esp/transport//require; __END (3) run "iperf3 -s" on 192.168.134.2 (4) run "iperf -c 192.168.134.2 -R" on 192.168.134.1 (5) Almost instant crash on 192.168.134.1. It looks have something to do with timings, as same setup where slow 192.168.134.1 is replaced bu much faster and AES-NI-capable system (same FreeBSD version) make crash much more hard to reproduce. I've got only one = for 6 hours of testing with fast system. --=20 You are receiving this mail because: You are the assignee for the bug.=
