[strongSwan] IKEv2 Extensions to Support RoHC (RFC 5857)

[Andreas Steffen]

Hi Jordan,

the ROHC_SUPPORTED notification type has already been defined
in src/libcharon/encoding/payloads/notify_payload.h:

https://git.strongswan.org/?p=strongswan.git;a=blob;f=src/libcharon/encoding/payloads/notify_payload.h;h=04160bbfcab1da805b41d43ce3e5e48976d3999c;hb=refs/heads/master#l128

What remains to be done is to write a libcharon plugin which inserts
RoHC attributes on the sender side and parses them on the receiver
side. This is done via a listener subscribed to notify messages.

Some time ago I created a "demo-plugin" git branch which shows what
has to be done to implement a custom-specific plugin transferring
information over notify messages:

https://git.strongswan.org/?p=strongswan.git;a=commitdiff;h=0c948b864f130756f40bb3cf04d2ef5beda12dce

I hope this helps.

Best regards

Andreas
