Isn't it depend on the agreement between caller that setup the data and the
called dissector that uses the data.If the caller wants to enforce it, that
is fine. But I don't see a general rule here. What if the case that
sub-dissector wants to pass back some value. private_data is also the only
way
Hello,
Am I correct that it is OK to use pinfo->private_data to pass information to
sub-dissectors?
Should dissector save pinfo->private_data and restore it after calling all
sub-dissectors it needs?
I've seen plenty of dissectors which do not follow this rule and going to fix
them.
