Subject: [PATCH] key: fix setkey(8) policy set breakage
Steps to reproduce:
#/usr/sbin/setkey -f
flush;
spdflush;
add 192.168.0.42 192.168.0.1 ah 24500 -A hmac-md5 "1234567890123456";
add 192.168.0.42 192.168.0.1 esp 24501 -E 3des-cbc "123456789012123456789012";
spdadd 192.168.0.42 192.168.0.1 any -P out ipsec
esp/transport//require
ah/transport//require;
setkey: invalid keymsg length
Policy dump will bail out with the same message after that.
