[strongSwan] Debug CFG_* messages (especially TSr and TSi)

[IL Ka]

Hello.

What is the best way to debug TSi and TSr messages?
I want to see CFG_REQUEST/CFR_REPLY conversation between server and client
(I am interested in TS and INTERNAL_IP4_* messages), but did not find any
option for that in charondebug

I wish there were an option to show debug like it is written in RFC5996:
   CP(CFG_REPLY) =
     INTERNAL_IP4_ADDRESS(198.51.100.234)
     INTERNAL_IP4_SUBNET(198.51.100.0/255.255.255.192)
     INTERNAL_IP4_SUBNET(192.0.2.0/255.255.255.0)
   TSi = (0, 0-65535, 198.51.100.234-198.51.100.234)
   TSr = ((0, 0-65535, 198.51.100.0-198.51.100.63),
          (0, 0-65535, 192.0.2.0-192.0.2.255))

Could be very useful both for debugging and understanding IKEv2.


Thank you in advance,
Ilya.
