Hello, all:
following is my setkey configration. I can get SAD and SPD. but when I
run " ping6 -I rl0 3ffe:501:ffff:103:20a:ebff:fe85:9e56 " on FreeBSD
FreeBSD report: kernel: esp_aesctr_decrypt aes-ctr:payload length must
be multiple of 16
kernel: decrypt fail in IPv6 ESP input :
SA(SPI 8192 src=3ffe:0501:ffff:0103:020a:ebff:fe85:9e56
dst=3ffe:0501:ffff:0104:021d:0fff:fe19:59fc)
but when I use "ping6 -I rl0 -s 4(or 6 or 20)
3ffe:501:ffff:103:20a:ebff:fe85:9e56"
that the report disappear. I read RFC, did not find the explain. could
you give me a explain?
Thanks
