2014-09-12net: arc_emac: prevent reuse of unreclaimed tx descriptorsBeniamino Galvani
This patch changes the logic in tx path to ensure that tx descriptors are reused for transmission only after they have been reclaimed by arc_emac_tx_clean(). Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-12net: arc_emac: enable tx interruptsBeniamino Galvani
In the current implementation the cleaning of tx ring is done by the NAPI poll handler, which is scheduled after rx interrupts. Thus, in absence of received packets the reclaim of used tx buffers is never executed, blocking further transmission. This can be easily reproduced starting the transmission of a UDP flow with iperf, which blocks almost immediately because skbs are not returned to the stack and the socket send buffer becomes full. The patch enables tx interrupts so that the tx reclaim is scheduled after completed transmissions.

2014-09-10net/mlx4: Set vlan stripping policy by the right commandMatan Barak
Changing the vlan stripping policy of the QP isn't supported by older firmware versions for the INIT2RTR command. Nevertheless, we've used it. Fix that by doing this policy change using INIT2RTR only if the firmware supports it, otherwise, we call UPDATE_QP command to do the task.

2014-09-10net/mlx4: Correctly configure single ported VFs from the hostMatan Barak
Single port VFs are seen PCI wise on both ports of the PF (we don't have single port PFs with ConnectX). With this in mind, it's possible for virtualization tools to try and configure a single ported VF through the "wrong" PF port. To handle that, we use the PF driver mapping of single port VFs to NIC ports and adjust the port value before calling into the low level code that does the actual VF configuration Fixes: 449fc48 ('net/mlx4: Adapt code for N-Port VF') Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.

There is a potential case where we might be failing to refill a control block, leaving it with both a NULL skb pointer *and* a NULL dma_unmap_addr. The way we process incoming packets, by first calling dma_unmap_single(), and then only checking for a potential NULL skb can lead to situations where do pass a NULL dma_unmap_addr() to dma_unmap_single(), resulting in an oops.

2014-09-08sunvnet - add missing rmb() for sunvnet driverDavid L Stevens
The sunvnet driver does not have an rmb() in the ring consumer corresponding to the wmb() in the producer. According to Documentation/memory-barriers.txt: "When dealing with CPU-CPU interactions, certain types of memory barrier should always be paired. A lack of appropriate pairing is almost certainly an error." In cases where an rmb() is not a no-op and a consumer is removing data from the ring while a producer is adding new entries, a load reorder would allow CPU1 CPU2 ---- ---- LOAD desc.size [e.g] STORE desc.size <wmb> set desc.hdr.state = VIO_DESC_READY LOAD desc.hdr.state [because VIO_DESC_READY, use old desc.size, already loaded out of order] [CPU2 has reordered apparently unrelated LOADs] To ensure other desc fields are not loaded before checking VIO_DESC_READY, we need an rmb() between the check and desc data accesses. I've also moved the viodbg() call to after the rmb() so that it, too, has current descriptor data even with reordering, which has the side effect that it won't print anything for descriptors that are not VIO_DESC_READY as before. That's a) probably a good thing, since the fields are not necessarily set and, b) better than adding another rmb() just for viodbg(). This would not be possible if strict-ordering is enforced, but then the memory barriers should be no-ops in that case.

For the mac80211 bits, Johannes says: "Here are a few fixes for mac80211. One has been discussed for a while and adds a terminating NUL-byte to the alpha2 sent to userspace, which shouldn't be necessary but since many places treat it as a string we couldn't move to just sending two bytes. In addition to that, we have two VLAN fixes from Felix, a mesh fix, a fix for the recently introduced RX aggregation offload, a revert for a broken patch (that luckily didn't really cause any harm) and a small fix for alignment in debugfs." For the iwlwifi bits, Emmanuel says: "I revert a patch that disabled CTS to self in dvm because users reported issues. The revert is CCed to stable since the offending patch was sent to stable too.

2014-09-05greth: moved TX ring cleaning to NAPI rx poll funcDaniel Hellstrom
This patch does not affect the 10/100 GRETH MAC. Before all GBit GRETH TX descriptor ring cleaning was done in start_xmit(), when descriptor list became full it activated TX interrupt to start the NAPI rx poll function to do TX ring cleaning. With this patch the TX descriptor ring is always cleaned from the NAPI rx poll function, triggered via TX or RX interrupt. Otherwise we could end up in TX frames being sent but not reported to the stack being sent. On the 10/100 GRETH this is not an issue since the SKB is copied&aligned into private buffers so that the SKB can be freed directly on start_xmit() Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S.

The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly.

This results in BUG at kernel/time/timer.c:945. Second, if ifdown (tg3_close) is called between tg3_io_error_detected() and tg3_io_resume() then tg3_napi_disable() is called twice without a tg3_napi_enable between. Once during tg3_io_error_detected() and again during tg3_close().

2014-09-01cxgb4: Fix for handling 1Gb/s SFP+ Transceiver ModulesHariprasad Shenai
We previously assumed that a Port's Capabilities and Advertised Capabilities would never change from Port Initialization time. This is no longer true when we can have 10Gb/s and 1Gb/s SFP+ Transceiver Modules randomly swapped. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

2014-09-01stmmac: only remove RXCSUM feature if no rx coe is availableGiuseppe CAVALLARO
In case of the HW is not able to do the receive checksum offloading the only feature to remove is NETIF_F_RXCSUM. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-01stmmac: fix the rx csum featureGiuseppe CAVALLARO
For new GMACs it is possible to turn-on/off the COE. In the current driver, when disabled the Rx-checksum via ethtool, the tool reported that csum was disabled but the HW continued to set the IPC. Indeed this is because the fix_features allows this. So the patch fixes this problem by adding the set_features. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

2014-09-01amd-xgbe: Fix the xpcs mmd debugfs supportLendacky, Thomas
The debugfs support for the xpcs registers did not properly use the specified mmd (xpcs_mmd entry) which resulted in the default mmd value always being used.

Linville says: ==================== pull request: wireless 2014-08-28 Please pull this batch of fixes intended for the 3.17 stream. For the Bluetooth/6LowPAN/802.15.4 bits, Johan says: 'It contains a connection reference counting fix for LE where a connection might stay up even though it should get disconnected. The other 802.15.4 6LoWPAN related patches were sent to the bluetooth tree by Alexander Aring and described as follows by him: " these patches contains patches for the bluetooth branch. This series includes memory leak fixes and an errno value fix. Also there are two patches for sending and receiving 1280 6LoWPAN packets, which makes the IEEE 802.15.4 6LoWPAN stack more RFC compliant. "' Along with that... Alexey Khoroshilov fixes a use-after-free bug on at76c50x-usb. Hauke Mehrtens adds a PCI ID to bcma. Himangi Saraogi fixes a silly "A || A" test in rtlwifi.

The value for LPI TW timer has to be updated to 0x1E that is the hardcoded value of 20.5us and it will apply to all EEE enabled Remote PHYs. Disadvantage is for PHY's that support lesser wakeup time but we can accept it waiting to implement LLDP to negotiate the Wakeup time of Remote PHY.
