Re: using pinfo structure to save data after first iteration

[Anders Broman <anders.broman () ericsson com>]

Hi,
Adding SRTP decryption to Wireshark would be a valuable enhancement so you should consider working through gerrit so we 
can see your code and comment on it. Glancing at the RTP code there seems to be some preparations done to handle SRTP 
are you using that?
I would look at decrypting the payload at the first iteration and save whatever data is needed in the conversation 
structure or in per packet data to use it in subsequent dissection of the frame. Are you adding the keys via a 
preference?
Regards
Anders

Hi guys,

I am trying to write a dissector for SRTP and need help in saving decrypted data in a way so as to pass it on to the 
dissector after the first iteration as I have trouble keeping track of the roc which changes after there is a rollover 
where the packets from first cycle are also being treated as part of second cycle (i.e the roc is incremented by 1).So 
I tried to use the pinfo strucure but found NO SUCCESS.Can someone please comment on this if it is doable,If so how do 
I go about it.or atleast point me in the right direction.Thanks a lot!
