I'm not sure why you need to set net.inet.ipsec.crypto_support to 1 for
this. Shouldn't be needed.
If you want to figure it out, you may place debug print into
sys/opencrypto/crypto.c, there is a crypto_newsession function and you
need to change this:
/* See if all the algorithms are supported. */
for (cr =3D cri; cr; cr =3D cr->cri_next)
if (cap->cc_alg[cr->cri_alg] =3D=3D 0)
break;
into something like this:
/* See if all the algorithms are supported. */
for (cr =3D cri; cr; cr =3D cr->cri_next)
if (cap->cc_alg[cr->cri_alg] =3D=3D 0) {
printf("IPSEC: Unsupported algorithm: %d.\n",
cr->cri_alg);
break;
}

It could be RELENG_5 specific, as it uses rijndael implementation
which was removed after RELENG_5 (there is no sys/opencrypto/rijndael.c
anymore). Maybe rijndael version from sys/crypto/ handles it better?
This needs to be verified.
