As I am not on the linux-kernel list currently, I would appreciate it if
you could please CC me (that funky looking From: address will get your
reply back to me :-) on any responses.
I am updating the ISC's DHCP package for Linux 2.[12]. Specifically I
am dealing with the networking changes in the 2.[12] kernels that
require substantial changes in the way the ISC DHCP's dhcp client works.
I am using the new Linux Packet Filter for doing some of the job. It is
cool stuff, but I am running into a problem. In <linux/filter.h> there
is a structure defined:
struct sock_filter /* Filter block */
{
u16 code; /* Actual filter code */
u8 jt; /* Jump true */
u8 jf; /* Jump false */
u32 k; /* Generic multiuse field */
};
which is required by the userspace "setsockopt()" call to install the
filter.
The problem is however, when I include <linux/filter.h> the u* types are
not defined. I cannot find a header file that defines them for
userspace programs. <asm/types.h> has the definitions that I want, but
they are wrapped with a _KERNEL_ macro.
Any ideas on how to best handle this situation?
BTW: I seem to be getting a:
dhclient uses obsolete (PF_INET,SOCK_PACKET)
message as well. If somebody can point me to what has obsoleted this
facility I will see about updating that part of the dhcp client as well.
Much thanks,
b.
