2017-04-18ixgbe: list X553 backplane speeds correctlyDon Skidmore
We forgot to indicate some of the supported speed on the X553 backplane. This patch attempts to correct for that. Signed-off-by: Don Skidmore <donald.c.skidmore@intel.com> Tested-by: Krishneil Singh <krishneil.k.singh@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2017-04-18ixgbe: Add X552 XFI backplane supportDon Skidmore
This patch add support for X552 XFI backplane interface. The XFI backplane requires a custom tuned link. HW/FW owns the link config for XF backplane and SW must not interfere with it.

2017-04-18ixgbe: Remove pr_cont usesJoe Perches
As pr_cont output can be interleaved by other processes, using pr_cont should be avoided where possible. Miscellanea: - Use a temporary pointer to hold the next descriptions and consolidate the pr_cont uses - Use the temporary buffer to hold the 8 u32 register values and emit those in a single go - Coalesce formats and logging neatening around those changes - Fix a defective output for the rx ring entry description when also emitting rx_buffer_info data This reduces overall object size a tiny bit too. $ size drivers/net/ethernet/intel/ixgbe/*.o* text data bss dec hex filename 62167 728 12 62907 f5bb drivers/net/ethernet/intel/ixgbe/ixgbe_main.o.new 62273 728 12 63013 f625 drivers/net/ethernet/intel/ixgbe/ixgbe_main.o.old Signed-off-by: Joe Perches <joe@perches.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

Benjamin Herrenschmidt says: ==================== ftgmac100: Rework batch 5 - Features This is the third spin of the fifth and last batch of updates to the ftgmac100 driver. This contains a few additional "features" such as: - Support for ethtool n-way reset - Multicast filtering & promisc support - Vlan offload - netpoll And a couple of misc bits. This also adds the device-tree binding documentation. v2. - Addresses review comments and adds a new patch fixing a theorical ordering issue in my new NAPI poll implementation - Add a bug fix (Patch 8/9) for a potential ordering issue in the new NAPI poll code. v3. - Rebase on net-next (fix conflict with an unrelated #include change series) - Update DT bindings better describing accepted phy-mode values ==================== Signed-off-by: David S.

2017-04-18ftgmac100: Fix potential ordering issue in NAPI pollBenjamin Herrenschmidt
We need to ensure the loads from the descriptor are done after the MMIO store clearing the interrupts has completed, otherwise we might still miss work. A read back from the MMIO register will "push" the posted store and ioread32 has a barrier on weakly aordered architectures that will order subsequent accesses.

2017-04-18sctp: process duplicated strreset asoc request correctlyXin Long
This patch is to fix the replay attack issue for strreset asoc requests. When a duplicated strreset asoc request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. But note that if the result saved in asoc is performed, the sender's next tsn and receiver's next tsn for the response chunk should be set. It's safe to get them from asoc. Because if it's changed, which means the peer has received the response already, the new response with wrong tsn won't be accepted by peer.

2017-04-18sctp: process duplicated strreset in and addstrm in requests correctlyXin Long
This patch is to fix the replay attack issue for strreset and addstrm in requests. When a duplicated strreset in or addstrm in request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. For strreset in or addstrm in request, if the receiver side processes it successfully, a strreset out or addstrm out request(as a response for that request) will be sent back to peer. reconf_time will retransmit the out request even if it's lost. So when receiving a duplicated strreset in or addstrm in request and it's result was performed, it shouldn't reply this request, but drop it instead.

2017-04-18sctp: process duplicated strreset out and addstrm out requests correctlyXin Long
Now sctp stream reconf will process a request again even if it's seqno is less than asoc->strreset_inseq. If one request has been done successfully and some data chunks have been accepted and then a duplicated strreset out request comes, the streamin's ssn will be cleared. It will cause that stream will never receive chunks any more because of unsynchronized ssn. It allows a replay attack. A similar issue also exists when processing addstrm out requests. It will cause more extra streams being added. This patch is to fix it by saving the last 2 results into asoc. When a duplicated strreset out or addstrm out request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. Note that it saves last 2 results instead of only last 1 result, because two requests can be sent together in one chunk. And note that when receiving a duplicated request, the receiver side will still reply it even if the peer has received the response. It's safe, As the response will be dropped by the peer.
