Subject: The get_mac function always returns unknown
Download (untitled) / with headers

Hi, The get_mac function always returns "unknown" whatever interface is looked for. Before the patch: $ LC_ALL=C perl -MNet::ARP -e '$mac = Net::ARP::get_mac("eth2"); print "$mac\n"' ioctl SIOCGIFHWADDR: No such device unknown After the patch: $ perl -MNet::ARP -e '$mac = Net::ARP::get_mac("eth2"); print "$mac\n"' 00:08:a1:96:82:35 The bug has been reported on Debian: The patch only fixes ARP.xs, but I think it would also be good to make sure the device name can fit into the destination buffer. [quote=get_mac_linux.c] strcpy(iface.ifr_name,dev); [/quote] could be replaced by: strncpy(iface.ifr_name, dev, IFNAMSIZ); iface.ifr_name[IFNAMSIZ-1] = '\0'; I have not checked in the other files. Regards,

From: Franck Joncourt <> Subject: [PATCH] fixes/get_mac The get_mac function always returns "unknown" whatever interface is looked for. The device argument of the get_mac function must be defined out of the CODE scope in ARP.xs. The current behavior creates an undefined string which is passed to the get_mac_linux function.
