+

+
+When using GRE redirection in WCCP, it sets the wrong skb->protocol,
+that is, ETH_P_IP instead of ETH_P_IPV6 for the encapuslated traffic.

+Subject: net/mlx4_core: Limit count field to 24 bits in qp_alloc_res
+
+From: Jack Morgenstein <jackm@dev.mellanox.co.il>
+
+[ Upstream commit 2d5c57d7fbfaa642fb7f0673df24f32b83d9066c ]
+
+Some VF drivers use the upper byte of "param1" (the qp count field)
+in mlx4_qp_reserve_range() to pass flags which are used to optimize
+the range allocation.
+
+Under the current code, if any of these flags are set, the 32-bit
+count field yields a count greater than 2^24, which is out of range,
+and this VF fails.
+
+As these flags represent a "best-effort" allocation hint anyway, they may
+safely be ignored. Therefore, the PF driver may simply mask out the bits.

+Subject: net: mvneta: fix Tx interrupt delay
+
+From: willy tarreau <w@1wt.eu>
+
+[ Upstream commit aebea2ba0f7495e1a1c9ea5e753d146cb2f6b845 ]
+
+The mvneta driver sets the amount of Tx coalesce packets to 16 by
+default. Normally that does not cause any trouble since the driver
+uses a much larger Tx ring size (532 packets). But some sockets
+might run with very small buffers, much smaller than the equivalent
+of 16 packets. This is what ping is doing for example, by setting
+SNDBUF to 324 bytes rounded up to 2kB by the kernel.
+
+The problem is that there is no documented method to force a specific
+packet to emit an interrupt (eg: the last of the ring) nor is it
+possible to make the NIC emit an interrupt after a given delay.
+
+In this case, it causes trouble, because when ping sends packets over
+its raw socket, the few first packets leave the system, and the first
+15 packets will be emitted without an IRQ being generated, so without
+the skbs being freed. And since the socket's buffer is small, there's
+no way to reach that amount of packets, and the ping ends up with
+"send: no buffer available" after sending 6 packets. Running with 3
+instances of ping in parallel is enough to hide the problem, because
+with 6 packets per instance, that's 18 packets total, which is enough
+to grant a Tx interrupt before all are sent.
+
+The original driver in the LSP kernel worked around this design flaw
+by using a software timer to clean up the Tx descriptors. This timer
+was slow and caused terrible network performance on some Tx-bound
+workloads (such as routing) but was enough to make tools like ping
+work correctly.
+
+Instead here, we simply set the packet counts before interrupt to 1.
+This ensures that each packet sent will produce an interrupt. NAPI
+takes care of coalescing interrupts since the interrupt is disabled
+once generated.
+
+No measurable performance impact nor CPU usage were observed on small
+nor large packets, including when saturating the link on Tx, and this
+fixes tools like ping which rely on too small a send buffer. If one
+wants to increase this value for certain workloads where it is safe
+to do so, "ethtool -C $dev tx-frames" will override this default
+setting.
+
+This fix needs to be applied to stable kernels starting with 3.10.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Daniel Borkmann <dborkman@redhat.com>
+
+[ Upstream commit 9772b54c55266ce80c639a80aa68eeb908f8ecf5 ]
+
+To accomodate for enough headroom for tunnels, use MAX_HEADER instead
+of LL_MAX_HEADER. Robert reported that he has hit after roughly 40hrs
+of trinity an skb_under_panic() via SCTP output path (see reference).
+I couldn't reproduce it from here, but not using MAX_HEADER as elsewhere
+in other protocols might be one possible cause for this.
+
+In any case, it looks like accounting on chunks themself seems to look
+good as the skb already passed the SCTP output path and did not hit
+any skb_over_panic(). Given tunneling was enabled in his .config, the
+headroom would have been expanded by MAX_HEADER in this case.

+
+[ Upstream commit a620a6bc1c94c22d6c312892be1e0ae171523125 ]
+
+If TX channels are set to 4 and RX channels are set to less than 4,
+using ethtool -L, the driver will try to initialize more RX channels
+than it has allocated, causing an oops.
+
+This fix only initializes the RX ring if it has been allocated.
