Subject: tnt uses obsolete (PF_INET,SOCK_PACKET)

Hi,

Nov 1 12:09:12 debian-f5ibh kernel: tnt uses obsolete (PF_INET,SOCK_PACKET)

I got often this message, it is harmless (seems to be). What does it means ?

it means it uses old support for PACKET sockets in PF_INET protocol
family, i.e. a call like socket(PF_INET,SOCK_PACKET,0) instead of the
special protocol family for this purpose called PF_PACKET. If you truss
tcpdump you will see something like this:

socket(PF_PACKET, SOCK_DGRAM, 0) = 3

which answers why you no longer get messages like "tcpdump uses
obsolete..." i.e. new tcpdump (as of a few years ago) does the right thing
(while your tnt, whatever that might be, doesn't).

f5ibh,

It means that it should be opening a PF_PACKET socket (see packet(7))
instead of a PF_INET, SOCK_PACKET (see COMPATIBILITY ip(7)):

"For compatibility with Linux 2.0, the obsolete socket(PF_INET,
SOCK_RAW, protocol) syntax is still supported to open a
packet(7) socket. This is deprecated and should be replaced by
socket(PF_PACKET, SOCK_RAW, protocol) instead. The main
difference is the new sockaddr_ll address structure for generic
link layer information instead of sockaddr_pkt." - ip(7)
