2014-12-29powerpc/kdump: Ignore failure in enabling big endian exception during crashHari Bathini
In LE kernel, we currently have a hack for kexec that resets the exception endian before starting a new kernel as the kernel that is loaded could be a big endian or a little endian kernel. In kdump case, resetting exception endian fails when one or more cpus is disabled. But we can ignore the failure and still go ahead, as in most cases crashkernel will be of same endianess as primary kernel and reseting endianess is not even needed in those cases. This patch adds a new inline function to say if this is kdump path. This function is used at places where such a check is needed.

2014-12-28kvm: fix sorting of memslots with base_gfn == 0Paolo Bonzini
Before commit 0e60b0799fed (kvm: change memslot sorting rule from size to GFN, 2014-12-01), the memslots' sorting key was npages, meaning that a valid memslot couldn't have its sorting key equal to zero. On the other hand, a valid memslot can have base_gfn == 0, and invalid memslots are identified by base_gfn == npages == 0. Because of this, commit 0e60b0799fed broke the invariant that invalid memslots are at the end of the mslots array. When a memslot with base_gfn == 0 was created, any invalid memslot before it were left in place. This can be fixed by changing the insertion to use a ">=" comparison instead of "<=", but some care is needed to avoid breaking the case of deleting a memslot; see the comment in update_memslots.

2014-12-27netlink/genetlink: pass network namespace to bind/unbindJohannes Berg
Netlink families can exist in multiple namespaces, and for the most part multicast subscriptions are per network namespace. Thus it only makes sense to have bind/unbind notifications per network namespace. To achieve this, pass the network namespace of a given client socket to the bind/unbind functions. Also do this in generic netlink, and there also make sure that any bind for multicast groups that only exist in init_net is rejected. This isn't really a problem if it is accepted since a client in a different namespace will never receive any notifications from such a group, but it can confuse the family if not rejected (it's also possible to silently (without telling the family) accept it, but it would also have to be ignored on unbind so families that take any kind of action on bind/unbind won't do unnecessary work for invalid clients like that.

Johannes Berg says: ==================== netlink/genetlink cleanups & multicast improvements I'm looking at using the multicast group functionality in a way that would benefit from knowing when there are subscribers to avoid collecting the required data when there aren't any. During this I noticed that the unbind for multicast groups doesn't actually work - it's never called when sockets are closed. Luckily, nobody actually uses the functionality. While looking at the code trying to find why it's not called and where the multicast listeners are actually removed, I found the potential cleanup in patch 3. Patch 2 also has a cleanup for a generic netlink API in this area. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-12-27netlink: call unbind when releasing socketJohannes Berg
Currently, netlink_unbind() is only called when the socket explicitly unbinds, which limits its usefulness (luckily there are no users of it yet anyway.) Call netlink_unbind() also when a socket is released, so it becomes possible to track listeners with this callback and without also implementing a netlink notifier (and checking netlink_has_listeners() in there.)

2014-12-27netlink: update listeners directly when removing socketJohannes Berg
The code is now confusing to read - first in one function down (netlink_remove) any group subscriptions are implicitly removed by calling __sk_del_bind_node(), but the subscriber database is only updated far later by calling netlink_update_listeners(). Move the latter call to just after removal from the list so it is easier to follow the code. This also enables moving the locking inside the kernel-socket conditional, which improves the normal socket destruction path.

2014-12-27genetlink: pass only network namespace to genl_has_listeners()Johannes Berg
There's no point to force the caller to know about the internal genl_sock to use inside struct net, just have them pass the network namespace. This doesn't really change code generation since it's an inline, but makes the caller less magic - there's never any reason to pass another socket.

2014-12-26net: Generalize ndo_gso_check to ndo_features_checkJesse Gross
GSO isn't the only offload feature with restrictions that potentially can't be expressed with the current features mechanism. Checksum is another although it's a general issue that could in theory apply to anything. Even if it may be possible to implement these restrictions in other ways, it can result in duplicate code or inefficient per-packet behavior. This generalizes ndo_gso_check so that drivers can remove any features that don't make sense for a given packet, similar to netif_skb_features(). It also converts existing driver restrictions to the new format, completing the work that was done to support tunnel protocols since the issues apply to checksums as well. By actually removing features from the set that are used to do offloading, it solves another problem with the existing interface. In these cases, GSO would run with the original set of features and not do anything because it appears that segmentation is not required.

Note that the warning is associated with the container eth0. The skbs from sky2 have ip_summed set to CHECKSUM_COMPLETE, and because the packet is an encapsulated Ethernet frame, the checksum generated by the hardware includes the inner protocol and Ethernet headers. The receive code is careful to update the skb->csum, except in __dev_forward_skb, as called by dev_forward_skb. __dev_forward_skb calls eth_type_trans, which in turn calls skb_pull_inline(skb, ETH_HLEN) to skip over the Ethernet header, but does not update skb->csum when doing so. This patch resolves the problem by adding a call to skb_postpull_rcsum to update the skb->csum after the call to eth_type_trans.

The output memory operand and the input register operand both need to be reloaded using a register in class R1_REGS when generating 64-bit code.

This change is necessary to support HW which provides a total of more than 15 stream DMA engines which with legacy implementation causes an overflow on SDxCTL.STRM field (and the whole SDxCTL register) and as a result usage of Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

2014-12-24Bluetooth: Fix accepting connections when not using mgmtJohan Hedberg
When connectable mode is enabled (page scan on) through some non-mgmt method the HCI_CONNECTABLE flag will not be set. For backwards compatibility with user space versions not using mgmt we should not require HCI_CONNECTABLE to be set if HCI_MGMT is not set.

2014-12-24Bluetooth: Fix controller configuration with HCI_QUIRK_INVALID_BDADDRMarcel Holtmann
When controllers set the HCI_QUIRK_INVALID_BDADDR flag, it is required by userspace to program a valid public Bluetooth device address into the controller before it can be used. After successful address configuration, the internal state changes and the controller runs the complete initialization procedure. However one small difference is that this is no longer the HCI_SETUP stage. The HCI_SETUP stage is only valid during initial controller setup. In this case the stack runs the initialization as part of the HCI_CONFIG stage. The controller version information, default name and supported commands are only stored during HCI_SETUP. While these information are static, they are not read initially when HCI_QUIRK_INVALID_BDADDR is set. So when running in HCI_CONFIG state, these information need to be updated as well. This especially impacts Bluetooth 4.1 and later controllers using extended feature pages and second event mask page.

2014-12-24brcmfmac: Do not crash if platform data is not populatedMika Westerberg
The driver looks for pdata->oob_irq_supported to find out if wowl can be supported. However, not all platforms populate pdata in which case we crash the kernel because of NULL pointer dereference.

2014-12-24ipw2200: select CFG80211_WEXTPaul Bolle
Commit 24a0aa212ee2 ("cfg80211: make WEXT compatibility unselectable") made it impossible to depend on CFG80211_WEXT. It does still allow to select that symbol. (Yes, the commit summary is confusing.) So make IPW2200 select CFG80211_WEXT, so that the ipw2200 driver can be enabled in config again.

2014-12-24ASoC: rockchip: i2s: fix error defination of transmit data levelJianqun Xu
According to description about "Transmit Data Level", This bit field controls the level at which a DMA request is made by the transmit logic. It is equal to the watermark level. That is, the dma_tx_req signal is generated when the number of valid data entries in the TXFIFO (TXFIFO0 if CSR=00 TXFIFO1 if CSR=01 TXFIFO2 if CSR=10 TXFIFO3 if CSR=11) is equal to or below this field value. Different to receive data level, transmit data level does not need to "-1". Signed-off-by: Jianqun Xu <jay.xu@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-12-24ASoC: Intel: correct the fixed free block allocationJie Yang
For block span more than 1 section, when allocate it from a free block, we need allocate the remain buffers within the block, and then continue alloc the rest of needed size buffer. Here also make sure this free block is moved from free list to used list, and add it to block_list which may be used for power gating disabling later.
