2017-08-30IB/core: Add support to finalize objects in one transactionMatan Barak
The new ioctl based infrastructure either commits or rollbacks all objects of the method as one transaction. In order to do that, we introduce a notion of dealing with a collection of objects that are related to a specific method. This also requires adding a notion of a method and attribute. A method contains a hash of attributes, where each bucket contains several attributes. The attributes are hashed according to their namespace which resides in the four upper bits of the id. For example, an object could be a CQ, which has an action of CREATE_CQ. This action has multiple attributes. For example, the CQ's new handle and the comp_channel. Each layer in this hierarchy - objects, methods and attributes is split into namespaces. The basic example for that is one namespace representing the default entities and another one representing the driver specific entities. When declaring these methods and attributes, we actually declare their specifications. When a method is executed, we actually allocates some space to hold auxiliary information. This auxiliary information contains meta-data about the required objects, such as pointers to their type information, pointers to the uobjects themselves (if exist), etc. The specification, along with the auxiliary information we allocated and filled is given to the finalize_objects function.

2017-08-30IB/core: Add a generic way to execute an operation on a uobjectMatan Barak
The ioctl infrastructure treats all user-objects in the same manner. It gets objects ids from the user-space and by using the object type and type attributes mentioned in the object specification, it executes this required method. Passing an object id from the user-space as an attribute is carried out in three stages. The first is carried out before the actual handler and the last is carried out afterwards. The different supported operations are read, write, destroy and create. In the first stage, the former three actions just fetches the object from the repository (by using its id) and locks it. The last action allocates a new uobject. Afterwards, the second stage is carried out when the handler itself carries out the required modification of the object. The last stage is carried out after the handler finishes and commits the result. The former two operations just unlock the object. Destroy calls the "free object" operation, taking into account the object's type and releases the uobject as well. Creation just adds the new uobject to the repository, making the object visible to the application. In order to abstract these details from the ioctl infrastructure layer, we add uverbs_get_uobject_from_context and uverbs_finalize_object functions which corresponds to the first and last stages respectively.

2017-08-30ALSA: pcm: Fix power lock unbalance via OSS emulationTakashi Iwai
PCM OSS emulation issues the drain ioctl without power lock. It used to work in the earlier kernels as the power lock was taken inside snd_pcm_drain() itself. But since 68b4acd32249 ("ALSA: pcm: Apply power lock globally to common ioctls"), the power lock is taken outside the function. Due to that change, the call via OSS emulation leads to the unbalanced power lock, thus it deadlocks. As a quick fix, just take the power lock before snd_pcm_drain() call for OSS emulation path. A better cleanup will follow later.

The host is no longer aware of STAs PS status because of buffer station offload, so we can't rely on mac80211 to toggle on IEEE80211_TX_CTL_NO_PS_BUFFER bit. A possible issue with buffering such frames, beside the obvious spec violation, is when a station disconnects while in PS but the AP isn't aware of that. In such scenarios the AP won't be able to send probe responses or auth frames so the STA won't be able to reconnect and the AP will have a queue hang.

It does: lea 0x8(%rsp), %rcx ... mov %rcx, %rsp Instead of the obvious: add $0x8, %rsp It makes no sense to use an intermediate register, so I opened a GCC bug to track it: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81813 But it's not exactly a high-priority bug and it looks like we'll be stuck with this issue for a while. So for now we have to track register values when they're loaded with stack pointer offsets. This is kind of a big workaround for a tiny problem, but c'est la vie. I hope to eventually create a GCC plugin to implement a big chunk of objtool's functionality. Hopefully at that point we'll be able to remove of a lot of these GCC-isms from the objtool code.

2017-08-30cpuidle: Eliminate the CPUIDLE_DRIVER_STATE_START symbolRafael J. Wysocki
On some architectures the first (index 0) idle state is a polling one and it doesn't really save energy, so there is the CPUIDLE_DRIVER_STATE_START symbol allowing some pieces of cpuidle code to avoid using that state. However, this makes the code rather hard to follow. It is better to explicitly avoid the polling state, so add a new cpuidle state flag CPUIDLE_FLAG_POLLING to mark it and make the relevant code check that flag for the first state instead of using the CPUIDLE_DRIVER_STATE_START symbol. In the ACPI processor driver that cannot always rely on the state flags (like before the states table has been set up) define a new internal symbol ACPI_IDLE_STATE_START equivalent to the CPUIDLE_DRIVER_STATE_START one and drop the latter.

2017-08-29neigh: increase queue_len_bytes to match wmem_defaultEric Dumazet
Florian reported UDP xmit drops that could be root caused to the too small neigh limit. Current limit is 64 KB, meaning that even a single UDP socket would hit it, since its default sk_sndbuf comes from net.core.wmem_default (~212992 bytes on 64bit arches). Once ARP/ND resolution is in progress, we should allow a little more packets to be queued, at least for one producer. Once neigh arp_queue is filled, a rogue socket should hit its sk_sndbuf limit and either block in sendmsg() or return -EAGAIN.

2017-08-29net: bcmgenet: Use correct I/O accessorsFlorian Fainelli
The GENET driver currently uses __raw_{read,write}l which means native I/O endian. This works correctly for an ARM LE kernel (default) but fails miserably on an ARM BE (BE8) kernel where registers are kept little endian, so replace uses with {read,write}l_relaxed here which is what we want because this is all performance sensitive code.

2017-08-29nfp: double free on error in probeDan Carpenter
Both the nfp_net_pf_app_start() and the nfp_net_pci_probe() functions call nfp_net_pf_app_stop_ctrl(pf) so there is a double free. The free should be done from the probe function because it's allocated there so I have removed the call from nfp_net_pf_app_start().
