2017-08-30mmc: renesas-sdhi: add support for R-Car Gen3 SDHI DMACSimon Horman
Add a new variant of the SDHI driver to support R-Car Gen3 with DMA via on-chip bus mastering. Since the DMAC is in a part of the SDHI module it is not suitable to be used via DMA Engine.

2017-08-30irqchip: mips-gic: SYNC after enabling GIC regionJames Hogan
A SYNC is required between enabling the GIC region and actually trying to use it, even if the first access is a read, otherwise its possible depending on the timing (and in my case depending on the precise alignment of certain kernel code) to hit CM bus errors on that first access. Add the SYNC straight after setting the GIC base.

2017-08-30iwlwifi: mvm: Avoid deferring non bufferable framesDavid Spinadel
Use bcast station for all non bufferable frames on AP and AD-HOC. 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.

2017-08-30objtool: Handle GCC stack pointer adjustment bugJosh Poimboeuf
Arnd Bergmann reported the following warning with GCC 7.1.1: fs/fs_pin.o: warning: objtool: pin_kill()+0x139: stack state mismatch: cfa1=7+88 cfa2=7+96 And the kbuild robot reported the following warnings with GCC 5.4.1: fs/fs_pin.o: warning: objtool: pin_kill()+0x182: return with modified stack frame fs/quota/dquot.o: warning: objtool: dquot_alloc_inode()+0x140: stack state mismatch: cfa1=7+120 cfa2=7+128 fs/quota/dquot.o: warning: objtool: dquot_free_inode()+0x11a: stack state mismatch: cfa1=7+112 cfa2=7+120 Those warnings are caused by an unusual GCC non-optimization where it uses an intermediate register to adjust the stack pointer. 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.

2017-08-29amd-xgbe: Interrupt summary bits are h/w version dependentTom Lendacky
There is a difference in the bit position of the normal interrupt summary enable (NIE) and abnormal interrupt summary enable (AIE) between revisions of the hardware. For older revisions the NIE and AIE bits are positions 16 and 15 respectively. For newer revisions the NIE and AIE bits are positions 15 and 14. The effect in changing the bit position is that newer hardware won't receive AIE interrupts in the current version of the driver. Specifically, the driver uses this interrupt to collect statistics on when a receive buffer unavailable event occurs and to restart the driver/device when a fatal bus error occurs. Update the driver to set the interrupt enable bit based on the reported version of the hardware. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

Jiri Benc says: ==================== nsh: headers, GSO This adds header structs and helpers for NSH together with GSO support. Note there is no code in this patchset that actually manipulates the NSH headers. That was sent to netdev by Yi Yang ("[PATCH net-next v6 0/3] openvswitch: add NSH support"). The aim of this series is to lay the groundwork and ease the implementation for him. In addition to openvswitch, the NSH support should be added to tc (flower to match, act_nsh to push/pop NSH headers). That will come later. There's currently no plan to support NSH by other means than those two.

2017-08-29vxlan: factor out VXLAN-GPE next protocolJiri Benc
The values are shared between VXLAN-GPE and NSH. Originally probably by coincidence but I notified both working groups about this last year and they seem to keep the values in sync since then. Hopefully they'll get a single IANA registry for the values, too. (I asked them for that.) Factor out the code to be shared by the NSH implementation. NSH and MPLS values are added in this patch, too. For MPLS, the drafts incorrectly assign only a single value, while we have two MPLS ethertypes. I raised the problem with both groups. For now, I assume the value is for unicast. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Alexander Aring says: ==================== tc: act_ife: handle IEEE IFE ethertype as default this patch series will introduce the IFE ethertype which is registered by IEEE. If the netlink act_ife type netlink attribute is not given it will use this value by default now. At least it will introduce some UAPI testcases to check if the default type is used if not specified and vice versa. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-29tc-testing: add test for testing ife typeAlexander Aring
This patch adds a new testcase for the IFE type setting in tc. In case of user specified the type it will check if the ife is correctly configured to react on it. If it's not specified the default IFE type should be used. Signed-off-by: Alexander Aring <aring@mojatatu.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.

2017-08-29act_ife: use registered ife_type as fallbackAlexander Aring
This patch handles a default IFE type if it's not given by user space netlink api. The default IFE type will be the registered ethertype by IEEE for IFE ForCES.

2017-08-29if_ether: add forces ife lfb typeAlexander Aring
This patch adds the forces IFE lfb type according to IEEE registered ethertypes. See http://standards-oui.ieee.org/ethertype/eth.txt for more information. Since there exists the IFE subsystem it can be used there. This patch also use the correct word "ForCES" instead of "FoRCES" which is a spelling error inside the IEEE ethertype specification.

2017-08-29net:ethernet:aquantia: Fix for multicast filter handling.Igor Russkikh
Since the HW supports up to 32 multicast filters we should track count of multicast filters to avoid overflow. If we attempt to add >32 multicast filter - just set NETIF_ALLMULTI flag instead.

2017-08-29net:ethernet:aquantia: Workaround for HW checksum bug.Pavel Belous
The hardware has the HW Checksum Offload bug when small TCP patckets (with length <= 60 bytes) has wrong "checksum valid" bit. The solution is - ignore checksum valid bit for small packets (with length <= 60 bytes) and mark this as CHECKSUM_NONE to allow network stack recalculate checksum itself.
