* net: fix race condition in several drivers when reading statsKevin Groeneveld2012-07-221-2/+2
| | | | | | | | | | | 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 stallsEric Dumazet2012-06-111-1/+3
| | | | | | | | | | | | | 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 <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* dummy: Add ndo_uninit().Hiroaki SHIMODA2012-04-161-3/+3
| | | | | | | | | | | | | 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_typeDanny Kukawka2012-02-151-1/+2
| | | | | | | | | | | | | 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 <danny.kukawka@bisect.de> Signed-off-by: David S.

* net: remove NETIF_F_NO_CSUM feature bitMichał Mirosław2011-11-161-1/+1
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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 patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

| | | | | | | | | | | | It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it. The number of people that could object because they're maintaining unified 2.4 and 2.6 drivers is probably rather small.

* [RTNETLINK]: rtnl_link: allow specifying initial device addressPatrick McHardy2007-07-111-0/+12

* [RTNETLINK]: rtnl_link API simplificationPatrick McHardy2007-07-111-54/+3
| | | | | | | | | | | | | | All drivers need to unregister their devices in the module unload function. While doing so they must hold the rtnl and atomically unregister the rtnl_link ops as well. This makes the rtnl_link_unregister function that takes the rtnl itself completely useless. Provide default newlink/dellink functions, make __rtnl_link_unregister and rtnl_link_unregister unregister all devices with matching rtnl_link_ops and change the existing users to take advantage of that.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
