net: Fix unwanted sign extension in netdev_stats_to_stats64()
When converting net_device_stats to rtnl_link_stats64 sign extension is triggered on ILP32 machines as 6c1c509 changed the previous "ulong -> u64" conversion to "long -> u64" by accessing the net_device_stats fields through a (signed) atomic_long_t. This causes for example the received bytes counter to jump to 16EiB after having received 2^31 bytes. Casting the atomic value to "unsigned long" beforehand converting it into u64 avoids this. Fixes: 6c1c509 ("net: add atomic_long_t to net_device_stats fields") Signed-off-by: Felix Riemann <felix.riemann@sma.de> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
