[strongSwan] use PFKEY instead of NETLINK

[Ali Masoudi]

Hi

I use strongswan v5.0.0. I want to use PFKEY interace instead of
NETLINK. I configure strongswan with these parameters:

./configure --enable-openssl --disable-kernel-netlink
--enable-kernel-pfkey --enable-eap-radius --enable-xauth-eap
--enable-eap-tls --enable-eap-md5 --enable-mysql --enable-ldap

after executing make , I tried to start a test vpn but it seemed that
charon have missed some dependencies, here is the log:

00[LIB] feature CUSTOM:libcharon in 'charon' plugin has unsatisfied
dependency: CUSTOM:kernel-net
00[LIB] feature PRIVKEY:DSA in 'pem' plugin has unsatisfied
dependency: PRIVKEY:DSA
00[LIB] feature PUBKEY:ECDSA in 'pem' plugin has unsatisfied
dependency: PUBKEY:ECDSA
00[LIB] feature PUBKEY:DSA in 'pem' plugin has unsatisfied dependency:
PUBKEY:DSA
00[LIB] feature CERT_DECODE:X509_OCSP_REQUEST in 'pem' plugin has
unsatisfied dependency: CERT_DECODE:X509_OCSP_REQUEST
00[LIB]   failed to load CUSTOM:libcharon in critical plugin 'charon'
00[LIB] failed to load 1 feature in critical plugin 'charon'
00[DMN] initialization failed - aborting charon

I think it is because I disabled netlink in configuration, should I
use pfkey alongside of netlink? how can i use pfkey instead of
netlink?

Thanks in advance
