[PATCH] NET: Fix race condition about network device name allocation.

2007-06-11T18:37:14+00:00

Kenji Kaneshige found this race between device removal and
registration.  On unregister it is possible for the old device to
exist, because sysfs file is still open.  A new device with 'eth%d'
will select the same name, but sysfs kobject register will fial.

The following changes the shutdown order slightly. It hold a removes
the sysfs entries earlier (on unregister_netdevice), but holds a
kobject reference.  Then when todo runs the actual last put free
happens.

Fix IFB net driver input device crashes

2007-04-13T20:47:04+00:00

[IFB]: Fix crash on input device removal

The input_device pointer is not refcounted, which means the device may
disappear while packets are queued, causing a crash when ifb passes packets
with a stale skb->dev pointer to netif_rx().

Fix by storing the interface index instead and do a lookup where neccessary.

NET_SCHED: Fix ingress qdisc locking.

2007-04-06T10:43:13+00:00

[NET_SCHED]: Fix ingress locking

Ingress queueing uses a seperate lock for serializing enqueue operations,
but fails to properly protect itself against concurrent changes to the
qdisc tree. Use queue_lock for now since the real fix it quite intrusive.

[PATCH] hotplug CPU: clean up hotcpu_notifier() use

2006-12-07T16:39:39+00:00

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add
#ifdefs.

the compiler can skip truly unused functions just fine:

    text    data     bss     dec     hex filename

[PATCH] netdev: don't allow register_netdev with blank name

2006-12-02T05:16:37+00:00

This bit of old backwards compatibility cruft can be removed in 2.6.20.
If there is still an device that calls register_netdev()
with a zero or blank name, it will get -EINVAL from register_netdevice().

[PATCH] rename net_random to random32

2006-10-17T15:18:43+00:00

Make net_random() more widely available by calling it random32

akpm: hopefully this will permit the removal of carta_random32.  That needs
confirmation from Stephane - this code looks somewhat more computationally
expensive, and has a different (ie: callee-stateful) interface.
