We did a failed attempt in the past to only use rcu in rtnl dump operations (commit e67f88dd "net: dont hold rtnl mutex during netlink dump callbacks") Now that dumps are holding RTNL anyway, there is no need to also use rcu locking, as it forbids any scheduling ability, like GFP_KERNEL allocations that controlling path should use instead of GFP_ATOMIC whenever possible.

Commit 740c7f31 ("sh_eth: Ensure DMA engines are stopped before freeing buffers") added a call to sh_eth_reset() to the sh_eth_set_ringparam() and sh_eth_close() paths. However, setting the software reset bit(s) in the EDMR register resets the MAC Address Registers to zero. Hence after kexec, the new kernel doesn't detect a valid MAC address and assigns a random MAC address, breaking DHCP. Set the MAC address again after the reset in sh_eth_dev_exit() to fix this. Tested on r8a7740/armadillo (GETHER) and r8a7791/koelsch (FAST_RCAR). Fixes: 740c7f31 ("sh_eth: Ensure DMA engines are stopped before freeing buffers") Signed-off-by:

This patch adds bcmgenet_tx_poll for the tx_rings. This can reduce the interrupt load and send xmit in network stack on time. This also separated for the completion of tx_ring16 from bcmgenet_poll. The bcmgenet_tx_reclaim of tx_ring[{0,1,2,3}] operative by an interrupt is to be not more than a certain number TxBDs. It is caused by too slowly reclaiming the transmitted skb. Therefore, performance degradation of xmit after 605ad7f1 ("tcp: refine TSO autosizing"). Signed-off-by:Jaedon Shin <jaedon.shin@gmail.com> Signed-off-by:

Brian reported crashes using IPv6 traffic with macvtap/veth combo. I tracked the crashes in neigh_hh_output() -> memcpy(skb->data - HH_DATA_MOD, hh->hh_data, HH_DATA_MOD); Neighbour code assumes headroom to push Ethernet header is at least 16 bytes. It appears macvtap has only 14 bytes available on arches where NET_IP_ALIGN is 0 (like x86) Effect is a corruption of 2 bytes right before skb->head, and possible crashes if accessing non existing memory. This fix should also increase IPv4 performance, as paranoid code in ip_finish_output2() wont have to call skb_realloc_headroom() Reported-by:

Prior to this patch, sending a packet with the source MAC address of one of the CPSW interfaces to one of the CPSW slave ports while it's configured in dual_emac mode would update the port_num field of the VLAN/Unicast Address Table Entry. This would cause it to discard all incoming traffic addressed to that MAC address, essentially rendering the port useless until the ALE table is cleared (by starting and stopping the interface or rebooting.) For example, if eth0 has a MAC address of 90:59:af:8f:43:e9 it will have an ALE table entry: 00 00 00 00 59 90 02 30 e9 43 8f af (VLAN Addr vlan_id=2 unicast type=0 port_num=0 addr=90:59:af:8f:43:e9) If you configure another device with the same MAC address and connect it to the first CPSW slave port and send some traffic the ALE table entry becomes: 04 00 00 00 59 90 02 30 e9 43 8f af (VLAN Addr vlan_id=2 unicast type=0 port_num=1 addr=90:59:af:8f:43:e9) >From this point forward all incoming traffic addressed to 90:59:af:8f:43:e9 will be dropped. Setting the SECURE bit for the VLAN/Unicast address table entry for each interface's MAC address corrects the problem. Signed-off-by:

There is a discrepancy here because the niu_class_to_ethflow() returns zero on failure and one on success but the caller expected zero on success and negative on failure. The problem means that we allow the user to pass classes and flow_types which we don't want. I've looked at it a bit and I don't see it as a very serious bug. Signed-off-by:

The smc91x driver traditionally gets configured at compile-time for whichever hardware it runs on. This no longer works on ARM as we continue to move to building all-in-one kernels. Most ARM configurations with this driver already use run-time configuration through DT or through platform_data, but a few have not been converted yet. I've checked all ARM boards that use this driver in their legacy board files, and converted the ones that were using compile-time configuration in smc91x.h to behave like the other ones and provide the interrupt polarity along with the MMIO configuration (width, stride) at platform device creation time. In particular, these combinations were previously selectable in Kconfig but in fact broken: - sa1100 assabet plus pleb - msm combined with any other armv6/v7 platform - pxa-idp combined with any non-DMA pxa variant - LogicPD PXA270 combined with any other pxa - nomadik combined with any other armv4/v5 platform, e.g. versatile. None of these seem critical enough to warrant a backport to stable, but it would be nice to clean this up for good. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-02-26 This series contains fixes for i40e and i40evf only. Alexey Khoroshilov found a possible leak of 'cmd_buf' when copy_from_user() failed in i40e_dbg_command_write(), so resolved by calling kfree(). Shannon provides a fix to ensure the shift and bitwise precedences do not work backwards for us by adding parans. Fixed the driver by preventing the driver from allowing stray interrupts or causing system logs from un-handled interrupts by combining the ICR0 shutdown with the standard interrupt shutdown and add the interrupt clearing to the PCI shutdown path. Fixed an issue where a NVM write times out before a transaction can complete, so Shannon added logic to make another attempt by reacquiring the semaphore, then retry the write, if the one retry fails, we will then give up. Adds checks to pointers before their use to ensure we do not try to dereference NULL pointers when returning values from the AdminQ calls. Akeem adds a check to bail out if the device is already down when checking for Tx hang subtask. Anjali fixes TSO with more than 8 frags per segment issue. The hardware has some limitations which the driver needs to adhere to: 1) no more than 8 descriptors per packet on the wire 2) no header can span more than 3 descriptors If one of these events happens, the hardware will generate an internal error and freeze the Tx queue, so Anjali fixes this by linearizes the skb to avoid these situations. Fixed an issue where the per Traffic Class queue count was higher than queues enabled, which will fix a warning with multiple function mode where systems regularly have more cores than vectors. Fixed TCP/IPv6 over VXLAN Tx checksum offload, where we were checking the outer protocol flags and deciding the flow for the inner header. Jesse fixes a race condition in the transmit hang detection. Before we were having issues of false Tx hang detection, no the driver makes more direct with the checks for progress forward by directly checking the head write back address and tail register when determining progress. This avoids Tx hangs where the software gets behind, because we are directly checking hardware state when determining a hang state. Neerav fixes the transmit ring Qset handle when DCB reconfigures. The issue was when DCB is reconfigured to a single traffic class (TC) and the driver did not reset the Tx ring Qset handle to correct the mapping, which caused the Tx queue to disable timeouts. Also as part of DCB reconfiguration flow if the Tx queue disable times out, then issue a PF reset to do some level of recovery. Mitch stops flow director on shutdown because, in some cases, the hardware would continue to try to access the FDIR ring after entering D3Hot state, which would cause either PCIe errors or NMIs, depending upon the system configuration. * NOTE * I have verified that this series of patches for net will not cause any merge issues when you sync up your net tree with your net-next tree. ==================== Signed-off-by: -

It is possible that the hardware may not have been properly shutdown before this driver gets control, through use by firmware, for example. Until the driver is loaded, interrupts associated with the hardware could go pending. When the IRQs are requested napi support has not been initialized yet, but the ISR will get control and schedule napi processing resulting in a kernel panic because the poll routine has not been set. Adjust the code so that the driver is fully ready to handle and process interrupts as soon as the IRQs are requested. This involves requesting and freeing IRQs during start and stop processing and ordering the napi add and delete calls appropriately. Also adjust the powerup and powerdown routines to match the start and stop routines in regards to the ordering of tasks, including napi related calls. Signed-off-by:

Daniel Borkmann says: ==================== rhashtable updates As discussed, I'm sending out rhashtable fixups for -net. I have a couple of more patches I was working on last week pending, i.e. to get rid of ht->nelems and ht->shift atomic operations which speed-up pure insertions/deletions, e.g. on my laptop I have 2 threads, inserting 7M entries each, that will reduce insertion time from ~1,450 ms to 865 ms (performance should even be better after removing the grow/shrink indirections). I guess that however is rather something for net-next. ==================== Signed-off-by: -

Currently, all real users of rhashtable default their grow and shrink decision functions to rht_grow_above_75() and rht_shrink_below_30(), so that there's currently no need to have this explicitly selectable. It can/should be generic and private inside rhashtable until a real use case pops up. Since we can make this private, we'll save us this additional indirection layer and can improve insertion/deletion time as well. Reference: http://patchwork.ozlabs.org/patch/443040/Suggested-by:

While commit c0c09bfd ("rhashtable: avoid unnecessary wakeup for worker queue") rightfully moved part of the decision making of whether we should expand or shrink from the expand/shrink functions themselves into insert/delete functions in order to avoid unnecessary worker wake-ups, it however introduced a regression by doing so. Before that change, if no max_shift was specified (= 0) on rhashtable initialization, rhashtable_expand() would just grow unconditionally and lets the available memory be the limiting factor. After that change, if no max_shift was specified, there would be _no_ expansion step at all. Given that netlink and tipc have a max_shift specified, it was not visible there, but Josh Hunt reported that if nft that starts out with a default element hint of 3 if not otherwise provided, would slow i.e. inserts down trememdously as it cannot grow larger to relax table occupancy. Given that the test case verifies shrinks/expands manually, we also must remove pointer to the helper functions to explicitly avoid parallel resizing on insertions/deletions. test_bucket_stats() and test_rht_lookup() could also be wrapped around rhashtable mutex to explicitly synchronize a walk from resizing, but I think that defeats the actual test case which intended to have explicit test steps, i.e. 1) inserts, 2) expands, 3) shrinks, 4) deletions, with object verification after each stage.

The current minstrel_ht rate control behavior is somewhat optimistic in trying to find optimum TX rate. While this is usually fine for normal Data frames, there are cases where a more conservative set of retry parameters would be beneficial to make the connection more robust. EAPOL frames are critical to the authentication and especially the EAPOL-Key message 4/4 (the last message in the 4-way handshake) is important to get through to the AP. If that message is lost, the only recovery mechanism in many cases is to reassociate with the AP and start from scratch. This can often be avoided by trying to send the frame with more conservative rate and/or with more link layer retries. In most cases, minstrel_ht is currently using the initial EAPOL-Key frames for probing higher rates and this results in only five link layer transmission attempts (one at high(ish) MCS and four at MCS0). While this works with most APs, it looks like there are some deployed APs that may have issues with the EAPOL frames using HT MCS immediately after association. Similarly, there may be issues in cases where the signal strength or radio environment is not good enough to be able to get frames through even at couple of MCS 0 tries. The best approach for this would likely to be to reduce the TX rate for the last rate (3rd rate parameter in the set) to a low basic rate (say, 6 Mbps on 5 GHz and 2 or 5.5 Mbps on 2.4 GHz), but doing that cleanly requires some more effort. For now, we can start with a simple one-liner that forces the minimum rate to be used for EAPOL frames similarly how the TX rate is selected for the IEEE 802.11 Management frames. This does result in a small extra latency added to the cases where the AP would be able to receive the higher rate, but taken into account how small number of EAPOL frames are used, this is likely to be insignificant. A future optimization in the minstrel_ht design can also allow this patch to be reverted to get back to the more optimized initial TX rate. It should also be noted that many drivers that do not use minstrel as the rate control algorithm are already doing similar workarounds by forcing the lowest TX rate to be used for EAPOL frames.
