net: fix race condition in several drivers when reading stats

2012-07-22T19:12:32Z

Fix race condition in several network drivers when reading stats on 32bit UP architectures. These drivers update their stats in a BH context and therefore should use u64_stats_fetch_begin_bh/u64_stats_fetch_retry_bh instead of u64_stats_fetch_begin/u64_stats_fetch_retry when reading the stats.

dummy: fix rcu_sched self-detected stalls

2012-06-11T08:12:04Z

Trying to "modprobe dummy numdummies=30000" triggers : INFO: rcu_sched self-detected stall on CPU { 8} (t=60000 jiffies) After this splat, RTNL is locked and reboot is needed. We must call cond_resched() to avoid this, even holding RTNL. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

dummy: Add ndo_uninit().

2012-04-17T03:56:36Z

In register_netdevice(), when ndo_init() is successful and later some error occurred, ndo_uninit() will be called. So dummy deivce is desirable to implement ndo_uninit() method to free percpu stats for this case. And, ndo_uninit() is also called along with dev->destructor() when device is unregistered, so in order to prevent dev->dstats from being freed twice, dev->destructor is modified to free_netdev().

net: use eth_hw_addr_random() and reset addr_assign_type

2012-02-15T20:34:17Z

Use eth_hw_addr_random() instead of calling random_ether_addr() to set addr_assign_type correctly to NET_ADDR_RANDOM. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: adapt to renamed eth_hw_addr_random() Signed-off-by: Danny Kukawka Signed-off-by: David S. Miller

net: remove NETIF_F_NO_CSUM feature bit

2011-11-16T22:43:12Z

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be enabled by default. The check heuristics is altered a bit here, so it hits other people than before. The default shouldn't be trusted for performance-critical cases anyway. For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM. Signed-off-by: Michał Mirosław Signed-off-by: David S.

net: remove use of ndo_set_multicast_list in drivers

net: call dev_alloc_name from register_netdevice

2011-05-05T17:57:45Z

Force dev_alloc_name() to be called from register_netdevice() by dev_get_valid_name(). That allows to remove multiple explicit dev_alloc_name() calls. The possibility to call dev_alloc_name in advance remains. This also fixes veth creation regresion caused by 84c49d8c3e4abefb0a41a77b25aa37ebe8d6b743 Signed-off-by: Jiri Pirko Signed-off-by: David S.

dummy: percpu stats and lockless xmit

2010-09-29T20:23:30Z

Converts dummy network device driver to : - percpu stats - 64bit stats - lockless xmit (NETIF_F_LLTX) - performance features added (NETIF_F_SG | NETIF_F_FRAGLIST | NETIF_F_TSO | NETIF_F_NO_CSUM | NETIF_F_HIGHDMA) Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
