ethertap
Hi!
According /usr/src/linux/Documentation/networking/ethertap.txt I've tried
to use ethertap for my experimental user space TCP/IP implementation
testing. I'm using kernel 2.2.19 (UP).
I load ethertap kernel module and configure it with ifconfig. Nice,
ping works, ifconfig show tap0. /dev/tap0 exists, major and minor is
correct.
But opening /dev/tap0 does not work!
munmap(0x127000, 55843) = 0
getpid()= 29070
open("/dev/tap0", O_RDWR|O_NONBLOCK)= -1 ENOSYS (Function not implemented)
open("/dev/tap0", O_RDWR|O_NONBLOCK)= -1 ENOSYS (Function not implemented)
open("/dev/tap0", O_RDWR|O_NONBLOCK)= -1 ENODEV (No such device)
write(2, "Cannot open /dev/tap0: No such d"..., 38Cannot open /dev/tap0: No such device
What can be the problem? How can I use /dev/tap0 then? I exactly followed
instructions read in ethertap.txt but it does not work ;-(((

mmap() question
Hi,
Sorry for my stupid question, but I haven't got idea what the problem can be,
and maybe you can help me. See the following fragment of C code:
videobuffer=mmap(0,MAX_VIDEO_PACKET_SIZE,PROT_READ|PROT_WRITE,MAP_ANON|MAP_SHARED,-1,0);
if (videobuffer==(void*)-1) {
perror("mmap()");
exit(1);
}
This will return with Invalid argument.
The nice this is that this code runs happyly with 2.4.x-pre kernels but not
with my 2.2.17 or 2.2.18pre15.
Maybe because of not page aligned size, so I modify my code:
I defined MAX_VIDEO_PACKET_SIZE to 4096 for testing (on PC page size is
4096 bytes, and getpagesize() returns with this as well, I checked).
The result is the same ! I don't understand what the problem can be ...
I tried with opening /dev/zero with O_RDWR mode than mapping that, but that
gave me the same result ;-(
I'm totally confused.
Can someone help, please ?
