Subject: i386 vs x86_64 struct tpacket_hdr layout
Date: Fri, 20 Dec 2013 14:30:06 +0100 [thread overview]
Message-ID: <52B4465E.2090904@aimvalley.nl> (raw)
I'm compiling my 32bit application with -m32 on a x86_64 system/kernel.
Things aren't working because for my application tp_len is at offset 4
but for the kernel it is at offset 8.
struct tpacket_hdr {
unsigned long tp_status;
unsigned int tp_len;
unsigned int tp_snaplen;
unsigned short tp_mac;
unsigned short tp_net;
unsigned int tp_sec;
unsigned int tp_usec;
};
How is this suppose to work ?
thanks,
Norbert van Bolhuis
