Yes, you may. Just suppround call with:

Yes, I figured that one out, thank you. But I still get the wrong
remote address.
Ifconfig says:
ppp0 Link encap:Point-to-Point Protocol
inet addr:201.1.1.1 P-t-P:201.1.1.2 Mask:255.255.255.0
UP POINTOPOINT RUNNING MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:7 Base address:0x360 Memory:c00ee000-c00effff
When I run the devinet_ioctl call in my module:
...
memset(&if_info, 0, sizeof(struct ifreq));
strcpy(if_info.ifr_name, dev->name);
set_fs(get_ds());
err = devinet_ioctl( SIOCGIFADDR, &if_info ); /*
Get local address */
if_data1 = (struct sockaddr_in *)&if_info.ifr_addr;
err = devinet_ioctl( SIOCGIFDSTADDR, &if_info ); /* Get
remote address */
if_data2 = (struct sockaddr_in *)&if_info.ifr_dstaddr;
set_fs(fs);
cfg.ip_options = 0x85;
cfg.ip_local = if_data1->sin_addr.s_addr;
cfg.ip_remote = if_data2->sin_addr.s_addr;
When I print the obtained addresses the results are:
if_data1->sin_addr.s_addr = 201.1.1.1
if_data2->sin_addr.s_addr = 201.1.1.1
As you can see the remote address is the same as the local one.
Ifconfig still gives the above result !?!?
Am I doing something wrong ?
I took a look at ifconfig source,
it seems that they are using sock->ops->ioctl calls to obtain
correct local and remote addresses.
could I use something like this in my driver ??? since
devinte_ioctl call is not working.
Thanks for you help,
