[User-mode-linux-devel] Misc problems with slip-based networking

[Yann D. <yd...@al...>]

Hi,

I'm running Debian "unstable" (aka "woody"), and the new ifconfig we
get (from net-tools 1.57) dose not understand the "-n" option.
Although the old ifconfig shipped with Debian 2.2 does understand it,
I do not find this option documented in the manpage or in --help
output.

Now I take an old ifconfig as um_ifconfig and get:

~/usr/src/umlinux[697]$ ./kernel-source-2.4.0-test9-um/linux ubd0=/home/dwitch/usr/src/umlinux/rootfs/root_fs_debian2.2_small umn=10.0.0.132
[...]
usermode:~# ifconfig umn 10.0.0.135 hw ether a:0:0:85:0:0
Failed to set slip line discipline - errno = 1
Failed to set O_ASYNC and O_NONBLOCK on fd # -1, errno = 9
umn_init : request_irq failed - errno = -1
SIOCSIFFLAGS: Operation not permitted
SIOCSIFADDR: Permission denied
sl-1: unknown interface: No such device
SIOCSIFDSTADDR: Permission denied
sl-1: unknown interface: No such device
sl-1: unknown interface: No such device
um_ifconfig failed
SIOCSIFHWADDR: Operation not permitted


Note I slightly edited um_ifconfig output, which looked like CR's were
just replaced with LF's.


It looks like set_umn_addr() gets passed -1 as device number.
Some sanity check appears to be missing...

Will recompile and try to run gdb on this.

Regards,
