2012-06-11dummy: fix rcu_sched self-detected stallsEric Dumazet1-1/+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>
2012-04-16dummy: Add ndo_uninit().Hiroaki SHIMODA1-3/+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().

2012-02-15net: use eth_hw_addr_random() and reset addr_assign_typeDanny Kukawka1-1/+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.

2011-11-16net: remove NETIF_F_NO_CSUM feature bitMichał Mirosław1-1/+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.

2011-05-05net: call dev_alloc_name from register_netdeviceJiri Pirko1-4/+0
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 <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-29dummy: percpu stats and lockless xmitEric Dumazet1-3/+55
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 <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-07-05net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy1-1/+1
This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2007-10-10[NET]: Nuke SET_MODULE_OWNER macro.Ralf Baechle1-1/+0
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.

2007-07-11[RTNETLINK]: rtnl_link: allow specifying initial device addressPatrick McHardy1-0/+12
Drivers need to validate the initial addresses in their netlink attribute validation function or manually reject them if they can't support this. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-11[RTNETLINK]: rtnl_link API simplificationPatrick McHardy1-54/+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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+152
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!
