2013-10-24ixgbe: cleanup ixgbe_enumerate_functionsJacob Keller
This function previously had the same check as used by the ixgbe_pcie_from_parent. As the hardcode is due to the device having an internal switch, this function should simply use the call from ixgbe_pcie_from_parent. This reduces code complexity and makes it less likely a developer will forget to update the list in the future.

A follow up issue, pci_enable_sriov() should only be called if no VFs were still allocated on module unload.

2013-10-24igbvf: integer wrapping bug setting the mtuDan Carpenter
If new_mtu is very large then "new_mtu + ETH_HLEN + ETH_FCS_LEN" can wrap and the check on the next line can underflow. This is one of those bugs which can be triggered by the user if you have namespaces configured. Also since this is something the user can trigger then we don't want to have dev_err() message. This is a static checker fix and I'm not sure what the impact is.

When a machine goes to S3/S4 after power-save is enabled, the runtime PM refcount might be incorrectly decreased because the power-down triggered soon after resume assumes that the controller was already powered up, and issues the pm_notify down.

2013-10-24md: avoid deadlock when md_set_badblocks.Bian Yu
When operate harddisk and hit errors, md_set_badblocks is called after scsi_restart_operations which already disabled the irq. but md_set_badblocks will call write_sequnlock_irq and enable irq. so softirq can preempt the current thread and that may cause a deadlock. I think this situation should use write_sequnlock_irqsave/irqrestore instead. I met the situation and the call trace is below: [ 638.919974] BUG: spinlock recursion on CPU#0, scsi_eh_13/1010 [ 638.921923] lock: 0xffff8800d4d51fc8, .magic: dead4ead, .owner: scsi_eh_13/1010, .owner_cpu: 0 [ 638.923890] CPU: 0 PID: 1010 Comm: scsi_eh_13 Not tainted 3.12.0-rc5+ #37 [ 638.925844] Hardware name: To be filled by O.E.M.

Since: commit 7ceb17e87bde79d285a8b988cfed9eaeebe60b86 md: Allow devices to be re-added to a read-only array. spares are activated on a read-only array. In case of raid1 and raid10 personalities it causes that not-in-sync devices are marked in-sync without checking if recovery has been finished. If a read-only array is degraded and one of its devices is not in-sync (because the array has been only partially recovered) recovery will be skipped. This patch adds checking if recovery has been finished before marking a device in-sync for raid1 and raid10 personalities. In case of raid5 personality such condition is already present (at raid5.c:6029). Bug was introduced in 3.10 and causes data corruption.

Antonio Quartulli says: ==================== this is another set of changes intended for net-next/linux-3.13. (probably our last pull request for this cycle) Patches 1 and 2 reshape two of our main data structures in a way that they can easily be extended in the future to accommodate new routing protocols. Patches from 3 to 9 improve our routing protocol API and its users so that all the protocol-related code is not mixed up with the other components anymore. Patch 10 limits the local Translation Table maximum size to a value such that it can be fully transfered over the air if needed. This value depends on fragmentation being enabled or not and on the mtu values. Patch 11 makes batman-adv send a uevent in case of soft-interface destruction while a "bat-Gateway" was configured (this informs userspace about the GW not being available anymore). Patches 13 and 14 enable the TT component to detect non-mesh client flag changes at runtime (till now those flags where set upon client detection and were not changed anymore). Patch 16 is a generalisation of our user-to-kernel space communication (and viceversa) used to exchange ICMP packets to send/received to/from the mesh network. Now it can easily accommodate new ICMP packet types without breaking the existing userspace API anymore. Remaining patches are minor changes and cleanups. ==================== Signed-off-by: David S.

Defer the generation of the first hash secret for the ipv4 fragmentation cache as late as possible. ip4_frags.rnd gets initial seeded by inet_frags_init and regulary reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly from ip_fragment.c in which case we initialize the secret directly. If we first get called by inet_frag_secret_rebuild we install a new secret by a manual call to get_random_bytes. This secret will be overwritten as soon as the first call to ipqhashfn happens.

Commit 8a07eb0a50 ("sctp: Add ASCONF operation on the single-homed host") implemented possible use of IPv4 addresses with non SCTP_ADDR_SRC state as source address when sending ASCONF (ADD) packets, but IPv6 part for that was not implemented in 8a07eb0a50. Therefore, as this is not restricted to IPv4-only, fix this up to allow the same for IPv6 addresses in SCTP.

2013-10-23net: always inline net_secret_initHannes Frederic Sowa
Currently net_secret_init does not get inlined, so we always have a call to net_secret_init even in the fast path. Let's specify net_secret_init as __always_inline so we have the nop in the fast-path without the call to net_secret_init and the unlikely path at the epilogue of the function. jump_labels handle the inlining correctly.

2013-10-23batman-adv: generalize batman-adv icmp packet handlingSimon Wunderlich
Instead of handling icmp packets only up to length of icmp_packet_rr, the code should handle any icmp length size. Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.

2013-10-23batman-adv: include the sync-flags when compute the global/local table CRCAntonio Quartulli
Flags covered by TT_SYNC_MASK are kept in sync among the nodes in the network and therefore they have to be considered while computing the global/local table CRC. In this way a generic originator is able to understand if its table contains the correct flags or not. Bits from 4 to 7 in the TT flags fields are now reserved for "synchronized" flags only. This allows future developers to add more flags of this type without breaking compatibility. It's important to note that not all the remote TT flags are synchronised. This comes from the fact that some flags are used to inject an information once only.

2013-10-23batman-adv: improve the TT component to support runtime flag changesAntonio Quartulli
Some flags (i.e. the WIFI flag) may change after that the related client has already been announced. However it is useful to informa the rest of the network about this change. Add a runtime-flag-switch detection mechanism and re-announce the related TT entry to advertise the new flag value. This mechanism can be easily exploited by future flags that may need the same treatment.

2013-10-23batman-adv: limit local translation table max sizeMarek Lindner
The local translation table size is limited by what can be transferred from one node to another via a full table request. The number of entries fitting into a full table request depend on whether the fragmentation is enabled or not. Therefore this patch introduces a max table size check and refuses to add more local clients when that size is reached. Moreover, if the max full table packet size changes (MTU change or fragmentation is disabled) the local table is downsized instantaneously.

2013-10-23batman-adv: provide orig_node routing APIAntonio Quartulli
Some operations executed on an orig_node depends on the current routing algorithm being used. To easily make this mechanism routing algorithm agnostic add a orig_node specific API that each algorithm can populate with its own routines. Such routines are then invoked by the code when needed, without knowing which routing algorithm is currently in use With this patch 3 API functions are added: - orig_free (to free routing depending internal structs) - orig_add_if (to change the inner state of an orig_node when a new hard interface is added) - orig_del_if (to change the inner state of an orig_node when an hard interface is removed) Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
