Hi John-Mark, the revision i built included gnn's patches to setkey already. I have tried to setup a tunnel using strongswan with gcm as esp cipher = mode, but the connection fails with "algorithm AES_GCM_16 not supported = by kernel".. Here's the full log output: Aug 3 00:34:28 00[DMN] Starting IKE charon daemon (strongSwan 5.3.2, = FreeBSD 11.0-CURRENT, amd64) Aug 3 00:34:28 00[KNL] unable to set UDP_ENCAP: Invalid argument Aug 3 00:34:28 00[NET] enabling UDP decapsulation for IPv6 on port 4500 = failed Aug 3 00:34:28 00[KNL] unable to set UDP_ENCAP: Invalid argument Aug 3 00:34:28 00[NET] enabling UDP decapsulation for IPv4 on port 4500 = failed Aug 3 00:34:28 00[CFG] loading ca certificates from = '/usr/local/etc/ipsec.d/cacerts' Aug 3 00:34:28 00[CFG] loading aa certificates from = '/usr/local/etc/ipsec.d/aacerts' Aug 3 00:34:28 00[CFG] loading ocsp signer certificates from = '/usr/local/etc/ipsec.d/ocspcerts' Aug 3 00:34:28 00[CFG] loading attribute certificates from = '/usr/local/etc/ipsec.d/acerts' Aug 3 00:34:28 00[CFG] loading crls from '/usr/local/etc/ipsec.d/crls' Aug 3 00:34:28 00[CFG] loading secrets from = '/usr/local/etc/ipsec.secrets' Aug 3 00:34:28 00[CFG] loaded IKE secret for @moon.strongswan.org = @sun.strongswan.org Aug 3 00:34:28 00[LIB] loaded plugins: charon aes des blowfish rc2 sha1 = sha2 md4 md5 random nonce x509 revocation constraints pubkey pkcs1 pkcs7 = pkcs8 pkcs12 pgp dnskey sshkey pem openssl fips-prf xcbc cmac hmac gcm = attr kernel-pfkey kernel-pfroute resolve socket-default stroke updown = eap-identity eap-md5 eap-mschapv2 eap-tls eap-ttls eap-peap = xauth-generic whitelist addrblock Aug 3 00:34:28 00[JOB] spawning 16 worker threads Aug 3 00:34:28 15[CFG] received stroke: add connection 'host-host' Aug 3 00:34:28 15[CFG] added configuration 'host-host' Aug 3 00:34:47 15[NET] received packet: from 10.0.30.109[500] to = 10.0.30.59[500] (448 bytes) Aug 3 00:34:47 15[ENC] parsed IKE_SA_INIT request 0 [ SA KE No = N(NATD_S_IP) N(NATD_D_IP) N(HASH_ALG) ] Aug 3 00:34:47 15[IKE] 10.0.30.109 is initiating an IKE_SA Aug 3 00:34:47 15[ENC] generating IKE_SA_INIT response 0 [ SA KE No = N(NATD_S_IP) N(NATD_D_IP) N(HASH_ALG) N(MULT_AUTH) ] Aug 3 00:34:47 15[NET] sending packet: from 10.0.30.59[500] to = 10.0.30.109[500] (448 bytes) Aug 3 00:34:47 15[NET] received packet: from 10.0.30.109[4500] to = 10.0.30.59[4500] (282 bytes) Aug 3 00:34:47 15[ENC] parsed IKE_AUTH request 1 [ IDi N(INIT_CONTACT) = IDr AUTH N(ESP_TFC_PAD_N) SA TSi TSr N(MOBIKE_SUP) N(ADD_6_ADDR) = N(MULT_AUTH) N(EAP_ONLY) ] Aug 3 00:34:47 15[CFG] looking for peer configs matching = 10.0.30.59[sun.strongswan.org]...10.0.30.109[moon.strongswan.org] Aug 3 00:34:47 15[CFG] selected peer config 'host-host' Aug 3 00:34:47 15[IKE] authentication of 'moon.strongswan.org' with = pre-shared key successful Aug 3 00:34:47 15[IKE] received ESP_TFC_PADDING_NOT_SUPPORTED, not = using ESPv3 TFC padding Aug 3 00:34:47 15[IKE] peer supports MOBIKE Aug 3 00:34:47 15[IKE] authentication of 'sun.strongswan.org' (myself) = with pre-shared key Aug 3 00:34:47 15[IKE] IKE_SA host-host[1] established between = 10.0.30.59[sun.strongswan.org]...10.0.30.109[moon.strongswan.org] Aug 3 00:34:47 15[IKE] scheduling reauthentication in 3416s Aug 3 00:34:47 15[IKE] maximum IKE_SA lifetime 3596s Aug 3 00:34:47 15[KNL] algorithm AES_GCM_16 not supported by kernel!
