2010-05-24Revert "ath9k: Group Key fix for VAPs"Linus Torvalds1-1/+0
This reverts commit 03ceedea972a82d343fa5c2528b3952fa9e615d5, since it breaks resume from suspend-to-ram on Rafael's Acer Ferrari One. NetworkManager thinks everything is ok, but it can't connect to the AP to get an IP address after the resume. In fact, it even breaks resume for non-ath9k chipsets: reverting it also fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes says: "Indeed, this patch needs to be reverted.

2010-05-24cls_cgroup: Store classid in struct sockHerbert Xu3-16/+61
Up until now cls_cgroup has relied on fetching the classid out of the current executing thread. This runs into trouble when a packet processing is delayed in which case it may execute out of another thread's context. Furthermore, even when a packet is not delayed we may fail to classify it if soft IRQs have been disabled, because this scenario is indistinguishable from one where a packet unrelated to the current thread is processed by a real soft IRQ. In fact, the current semantics is inherently broken, as a single skb may be constructed out of the writes of two different tasks. A different manifestation of this problem is when the TCP stack transmits in response of an incoming ACK. This is currently unclassified. As we already have a concept of packet ownership for accounting purposes in the skb->sk pointer, this is a natural place to store the classid in a persistent manner. This patch adds the cls_cgroup classid in struct sock, filling up an existing hole on 64-bit :) The value is set at socket creation time. So all sockets created via socket(2) automatically gains the ID of the thread creating it. Whenever another process touches the socket by either reading or writing to it, we will change the socket classid to that of the process if it has a valid (non-zero) classid. For sockets created on inbound connections through accept(2), we inherit the classid of the original listening socket through sk_clone, possibly preceding the actual accept(2) call. In order to minimise risks, I have not made this the authoritative classid. For now it is only used as a backup when we execute with soft IRQs disabled. Once we're completely happy with its semantics we can use it as the sole classid. Footnote: I have rearranged the error path on cls_group module creation. If we didn't do this, then there is a window where someone could create a tc rule using cls_group before the cgroup subsystem has been registered.

2010-05-21net: Expose all network devices in a namespaces in sysfsEric W. Biederman3-39/+6
This reverts commit aaf8cdc34ddba08122f02217d9d684e2f9f5d575. Drivers like the ipw2100 call device_create_group when they are initialized and device_remove_group when they are shutdown. Moving them between namespaces deletes their sysfs groups early. In particular the following call chain results. netdev_unregister_kobject -> device_del -> kobject_del -> sysfs_remove_dir With sysfs_remove_dir recursively deleting all of it's subdirectories, and nothing adding them back. Ouch! Therefore we need to call something that ultimate calls sysfs_mv_dir as that sysfs function can move sysfs directories between namespaces without deleting their subdirectories or their contents. Allowing us to avoid placing extra boiler plate into every driver that does something interesting with sysfs. Currently the function that provides that capability is device_rename. That is the code works without nasty side effects as originally written. So remove the misguided fix for moving devices between namespaces. The bug in the kobject layer that inspired it has now been recognized and fixed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Acked-by: David S.

When netlink sockets are used to convey data that is in a namespace we need a way to select a subset of the listening sockets to deliver the packet to. For the network namespace we have been doing this by only transmitting packets in the correct network namespace. For data belonging to other namespaces netlink_bradcast_filtered provides a mechanism that allows us to examine the destination socket and to decide if we should transmit the specified packet to it.

2010-05-21net/sysfs: Fix the bitrot in network device kobject namespace supportEric W. Biederman2-13/+3
I had a couple of stupid bugs in: netns: Teach network device kobjects which namespace they are in. - I duplicated the Kconfig for the NET_NS - The build was broken when sysfs was not compiled in The sysfs breakage is because after I moved the operations for the sysfs to the kobject layer, to make things cleaner I forgot to move the ifdefs. Opps. I'm not quite certain how I got introduced a second NET_NS Kconfig, but it was probably a 3 way merge somewhere along the way that did not notice that the NET_NS Kconfig option had mvoed and thout that was a bug. It probably slipped in because it used to be the sysfs patches were the first patches in my network namespace patches. Some things just don't go like you would expect. Neither of these bugs actually affect anything in the common case but they should be fixed. Thanks to Serge for noticing they were present. Reported-by: Serge E.

2010-05-21netns: Teach network device kobjects which namespace they are in.Eric W. Biederman2-0/+55
The problem. Network devices show up in sysfs and with the network namespace active multiple devices with the same name can show up in the same directory, ouch! To avoid that problem and allow existing applications in network namespaces to see the same interface that is currently presented in sysfs, this patch enables the tagging directory support in sysfs. By using the network namespace pointers as tags to separate out the the sysfs directory entries we ensure that we don't have conflicts in the directories and applications only see a limited set of the network devices.

2010-05-21net: fix problem in dequeuing from input_pkt_queueTom Herbert1-13/+15
Fix some issues introduced in batch skb dequeuing for input_pkt_queue. The primary issue it that the queue head must be incremented only after a packet has been processed, that is only after __netif_receive_skb has been called. This is needed for the mechanism to prevent OOO packet in RFS. Also when flushing the input_pkt_queue and process_queue, the process queue should be done first to prevent OOO packets. Because the input_pkt_queue has been effectively split into two queues, the calculation of the tail ptr is no longer correct. The correct value would be head+input_pkt_queue->len+process_queue->len. To avoid this calculation we added an explict input_queue_tail in softnet_data. The tail value is simply incremented when queuing to input_pkt_queue.

2010-05-21gro: Fix bogus gso_size on the first fraglist entryHerbert Xu1-0/+1
When GRO produces fraglist entries, and the resulting skb hits an interface that is incapable of TSO but capable of FRAGLIST, we end up producing a bogus packet with gso_size non-zero. This was reported in the field with older versions of KVM that did not set the TSO bits on tuntap. This patch fixes that.

2010-05-20netfilter: nf_conntrack: fix a race in __nf_conntrack_confirm against ↵Joerg Marx1-0/+10
nf_ct_get_next_corpse() This race was triggered by a 'conntrack -F' command running in parallel to the insertion of a hash for a new connection. Losing this race led to a dead conntrack entry effectively blocking traffic for a particular connection until timeout or flushing the conntrack hashes again. Now the check for an already dying connection is done inside the lock. Signed-off-by: Joerg Marx <joerg.marx@secunet.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
