2008-08-13netns: Fix crash by making igmp per namespaceDaniel Lezcano
This patch makes the multicast socket to be per namespace. When a network namespace is created, other than the init_net and a multicast packet is received, the kernel goes to a hang or a kernel panic. How to reproduce ? * create a child network namespace * create a pair virtual device veth * ip link add type veth * move one side to the pair network device to the child namespace * ip link set netns <childpid> dev veth1 * ping -I veth0 224.0.0.1 The bug appears because the function ip_mc_init_dev does not initialize the different multicast fields as it exits because it is not the init_net.

Link order with external PHY When external PHY exists (second chip with the PHY to translate to another physical medium) the link with the eternal PHY and the network should be established before setting the link between the 5771x and the PHY. This is the right order and it is important when using autoneg - the link to the network should use the autoneg and the link between the two chips should be forced to the network result.

2008-08-13pkt_sched: Fix queue quiescence testing in dev_deactivate().David S. Miller
Based upon discussions with Jarek P. and Herbert Xu. First, we're testing the wrong qdisc. We just reset the device queue qdiscs to &noop_qdisc and checking it's state is completely pointless here. We want to wait until the previous qdisc that was sitting at the ->qdisc pointer is not busy any more. And that would be ->qdisc_sleeping. Because of how we propagate the samples qdisc pointer down into qdisc_run and friends via per-cpu ->output_queue and netif_schedule, we have to wait also for the __QDISC_STATE_SCHED bit to clear as well.

2008-08-13pktgen: prevent pktgen from using bad tx queueAndrew Gallatin
With the new multi-queue transmit code, it is possible to accidentally make pktgen pick a non-existing tx queue simply by using a stale script to drive pktgen. Access to this non-existing tx queue will then trigger a bad memory access and kill the machine. For example, setting "queue_map_max 2" will cause my machine to die when accessing a garbage spinlock in the non-existing tx queue: BUG: spinlock bad magic on CPU#0, kpktgend_0/564 lock: ffff88001ddf6718, .magic: ffffffff, .owner: /-1, .owner_cpu: 0 Pid: 564, comm: kpktgend_0 Not tainted 2.6.27-rc3 #35 Call Trace: [<ffffffff803a1228>] spin_bug+0xa4/0xac [<ffffffff803a1253>] _raw_spin_lock+0x23/0x123 [<ffffffff8055b06f>] _spin_lock_bh+0x17/0x1b [<ffffffff804cb57d>] pktgen_thread_worker+0xa97/0x1002 [<ffffffff8022874d>] ? finish_task_switch+0x38/0x97 [<ffffffff80242077>] ? autoremove_wake_function+0x0/0x36 [<ffffffff80242077>] ? autoremove_wake_function+0x0/0x36 [<ffffffff804caae6>] ? pktgen_thread_worker+0x0/0x1002 [<ffffffff80241a40>] kthread+0x44/0x6d [<ffffffff8020c399>] child_rip+0xa/0x11 [<ffffffff802419fc>] ? kthread+0x0/0x6d [<ffffffff8020c38f>] ? child_rip+0x0/0x11 The attached patch adds some sanity checking to prevent these sorts of configuration errors.

2008-08-11skbuff: Code readability NiTGerrit Renker
Inserting a space between the `-' improved the C readability (some languages allow hyphens within functions and variable names, which is confusing). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-11pkt_sched: Add BH protection for qdisc_stab_lock.Jarek Poplawski
Since qdisc_stab_lock is used in qdisc_put_stab(), which is called in BH context from __qdisc_destroy() RCU callback, softirq safe locking is needed. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-11ipvs: Explictly clear ip_vs_stats membersSimon Horman
In order to align the coding styles of ip_vs_zero_stats() and its child-function ip_vs_zero_estimator(), clear ip_vs_stats members explicitlty rather than doing a limited memset(). This was chosen over modifying ip_vs_zero_estimator() to use memset() as it is more robust against changes in members in the relevant structures. memset() would be prefered if all members of the structure were to be cleared.

2008-08-11ipvs: No need to zero out ip_vs_stats during initializationSven Wegener
It's a global variable and automatically initialized to zero. And now we can also initialize the lock at compile time. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Acked-by: Simon Horman <horms@verge.net.au>
2008-08-11ipvs: Embed estimator object into stats objectSven Wegener
There's no reason for dynamically allocating an estimator object for every stats object. Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.
