2016-12-23inet: fix IP(V6)_RECVORIGDSTADDR for udp socketsWillem de Bruijn
Socket cmsg IP(V6)_RECVORIGDSTADDR checks that port range lies within the packet. For sockets that have transport headers pulled, transport offset can be negative. Use signed comparison to avoid overflow.

2016-12-21tcp: add a missing barrier in tcp_tasklet_func()Eric Dumazet
Madalin reported crashes happening in tcp_tasklet_func() on powerpc64 Before TSQ_QUEUED bit is cleared, we must ensure the changes done by list_del(&tp->tsq_node); are committed to memory, otherwise corruption might happen, as an other cpu could catch TSQ_QUEUED clearance too soon. We can notice that old kernels were immune to this bug, because TSQ_QUEUED was cleared after a bh_lock_sock(sk)/bh_unlock_sock(sk) section, but they could have missed a kick to write additional bytes, when NIC interrupts for a given flow are spread to multiple cpus. Affected TCP flows would need an incoming ACK or RTO timer to add more packets to the pipe. So overall situation should be better now.

2016-12-21net: mvpp2: fix dma unmapping of TX buffers for fragmentsThomas Petazzoni
Since commit 71ce391dfb784 ("net: mvpp2: enable proper per-CPU TX buffers unmapping"), we are not correctly DMA unmapping TX buffers for fragments. Indeed, the mvpp2_txq_inc_put() function only stores in the txq_cpu->tx_buffs[] array the physical address of the buffer to be DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use skb_headlen(skb) to get the size to be unmapped. Both of this works fine for TX descriptors that are associated directly to a SKB, but not the ones that are used for fragments, with a NULL pointer as skb: - We have a NULL physical address when calling DMA unmap - skb_headlen(skb) crashes because skb is NULL This causes random crashes when fragments are used. To solve this problem, we need to: - Store the physical address of the buffer to be unmapped unconditionally, regardless of whether it is tied to a SKB or not. - Store the length of the buffer to be unmapped, which requires a new field. Instead of adding a third array to store the length of the buffer to be unmapped, and as suggested by David Miller, this commit refactors the tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is added. Therefore, instead of having three arrays to allocate/free, we have a single one, which also improve data locality, reducing the impact on the CPU cache.

2016-12-21net: ethernet: stmmac: dwmac-rk: make clk enablement first in powerupHeiko Stübner
Right now the dwmac-rk tries to set up the GRF-specific speed and link options before enabling clocks, phys etc and on previous socs this works because the GRF is supplied on the whole by one clock. On the rk3399 however the GRF (General Register Files) clock-supply has been split into multiple clocks and while there is no specific grf-gmac clock like for other sub-blocks, it seems the mac-specific portions are actually supplied by the general mac clock. This results in hangs on rk3399 boards if the driver is build as module. When built in te problem of course doesn't surface, as the clocks are of course still on at the stage before clock_disable_unused. To solve this, simply move the clock enablement to the first position in the powerup callback. This is also a good idea in general to enable clocks before everything else. Tested on rk3288, rk3368 and rk3399 the dwmac still works on all of them. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: David S. Miller <davem@davemloft.net>

With commit e49656147359 {"rtlwifi: Use dev_kfree_skb_irq instead of kfree_skb"), the method used to free an skb was changed because the kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb() guards against a NULL value for the argument. Routine dev_kfree_skb_irq() does not, and a test is needed to prevent kernel panics.

2016-12-20sctp: not copying duplicate addrs to the assoc's bind address listXin Long
sctp.local_addr_list is a global address list that is supposed to include all the local addresses. sctp updates this list according to NETDEV_UP/ NETDEV_DOWN notifications. However, if multiple NICs have the same address, the global list would have duplicate addresses. Even if for one NIC, promote secondaries in __inet_del_ifa can also lead to accumulating duplicate addresses. When sctp binds address 'ANY' and creates a connection, it copies all the addresses from global list into asoc's bind addr list, which makes sctp pack the duplicate addresses into INIT/INIT_ACK packets. This patch is to filter the duplicate addresses when copying the addrs from global list in sctp_copy_local_addr_list and unpacking addr_param from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list. Note that we can't filter the duplicate addrs when global address list gets updated, As NETDEV_DOWN event may remove an addr that still exists in another NIC.

2016-12-20Merge branch 'phy-broken-modes'David S. Miller
Jerome Brunet says: ==================== phy: Fix integration of eee-broken-modes The purpose of this series is to fix the integration of the ethernet phy property "eee-broken-modes" [0] The v3 of this series has been merged, missing a fix (error reported by kbuild robot) available in the v4 [1] More importantly, Florian opposed adding a DT property mapping a device register this directly [2]. The concern was that the property could be abused to implement platform configuration policy. After discussing it, I think we agreed that such information about the HW (defect) should appear in the platform DT. However, the preferred way is to add a boolean property for each EEE broken mode.

2016-12-20dt: bindings: net: use boolean dt properties for eee broken modesjbrunet
The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.

2016-12-20ratelimit: fix WARN_ON_RATELIMIT return valueJiri Slaby
The macro is to be used similarly as WARN_ON as: if (WARN_ON_RATELIMIT(condition, state)) do_something(); One would expect only 'condition' to affect the 'if', but WARN_ON_RATELIMIT does internally only: WARN_ON((condition) && __ratelimit(state)) So the 'if' is affected by the ratelimiting state too. Fix this by returning 'condition' in any case. Note that nobody uses WARN_ON_RATELIMIT yet, so there is nothing to worry about. But I was about to use it and was a bit surprised.

2016-12-20mm: fadvise: avoid expensive remote LRU cache draining after FADV_DONTNEEDJohannes Weiner
When FADV_DONTNEED cannot drop all pages in the range, it observes that some pages might still be on per-cpu LRU caches after recent instantiation and so initiates remote calls to all CPUs to flush their local caches. However, in most cases, the fadvise happens from the same context that instantiated the pages, and any pre-LRU pages in the specified range are most likely sitting on the local CPU's LRU cache, and so in many cases this results in unnecessary remote calls, which, in a loaded system, can hold up the fadvise() call significantly. [ I didn't record it in the extreme case we observed at Facebook, unfortunately. We had a slow-to-respond system and noticed it lru_add_drain_all() leading the profile during fadvise calls. This patch came out of thinking about the code and how we commonly call FADV_DONTNEED. FWIW, I wrote a silly directory tree walker/searcher that recurses through /usr to read and FADV_DONTNEED each file it finds. On a 2 socket 40 ht machine, over 1% is spent in lru_add_drain_all(). With the patch, that cost is gone; the local drain cost shows at 0.09%. ] Try to avoid the remote call by flushing the local LRU cache before even attempting to invalidate anything. It's a cheap operation, and the local LRU cache is the most likely to hold any pre-LRU pages in the specified fadvise range.
