Hi all,
The code to generate mac addresses for veth (generate_mac in veth.c)
uses the
Constant SW_OUI for upper 3 bytes, and random values for lower 3 bytes.
Thus
giving 2^24 possible values.
Isn't it better to use random numbers for all 6 bytes, like the code
in the linux kernel:
static inline void random_ether_addr(u8 *addr)
{
get_random_bytes (addr, ETH_ALEN);
addr [0] &= 0xfe; /* clear multicast bit */
addr [0] |= 0x02; /* set local assignment bit (IEEE802) */
}
That would make conflict less likely.
