Eric,
heh, things are worse. Multiple places you changes are CTR()
macros. Neither inet_ntoa() nor inet_ntoa_r() will work with
them. :(
Basicly non-constant strings can not be logged with KTR. All
the lines you touched should log actual binary value of the
IPv4 address.
I am not asking you to do this work! :) But I couldn't leave
that without a comment.
