* bcma: fix regression in interrupt assignment on mipsHauke Mehrtens2012-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | The wrong interrupts where assigned to the cores in bcma_core_mips_init(). This caused at least my serial console not to response to any input. This was caused by this patch which changed the order of the cores in the list: commit c334e25c9f3a95f2bd6b79fedc5170f17245b1c7 Author: Rafał Miłecki <zajec5@gmail.com> Date: Wed Jul 11 12:37:00 2012 +0200 bcma: add new cores at the end of list This should be fixed properly later so that the correct interrupt numbers are assigned to the cores independently from the ordering of the list. This patch restores the old behavior again. I will look into the problem more deeply later. I also changed the order of the list with the cores and their assigned interrupt number which gets printed to the log. Now they are printed in the same order like all the other lists of cores and like it was done before the patch which changed the order.

* qeth: repair crash in qeth_l3_vlan_rx_kill_vid()frank.blaschka@de.ibm.com2012-07-25
| | | | | | | | | | | | | | | Commit efc73f4b "net: Fix memory leak - vlan_info struct" adds deletion of VLAN 0 for devices with feature NETIF_F_HW_VLAN_FILTER. For driver qeth these are the layer 3 devices. Usually there exists no separate vlan net_device for VLAN 0. Thus the qeth functions qeth_l3_free_vlan_addresses4() and qeth_l3_free_vlan_addresses6() require an extra checking if function __vlan_find_dev_deep() returns with a net_device.

* mlx4: Add support for EEH error recoveryKleber Sacilotto de Souza2012-07-25
| | | | | | | | | | | | | | | | | | | | | Currently the mlx4 drivers don't have the necessary callbacks to implement EEH errors detection and recovery, so the PCI layer uses the probe and remove callbacks to try to recover the device after an error on the bus. However, these callbacks have race conditions with the internal catastrophic error recovery functions, which will also detect the error and this can cause the system to crash if both EEH and catas functions try to reset the device. This patch adds the necessary error recovery callbacks and makes sure that the internal catastrophic error functions will not try to reset the device in such scenarios. It also adds some calls to pci_channel_offline() to suppress reads/writes on the bus when the slot cannot accept I/O operations so we prevent unnecessary accesses to the bus and speed up the device removal.

Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer. Whereas the existing BQL (Byte Queue Limits) limits the pkt_sched --> netdevice queuing levels, this controls the TCP --> pkt_sched queueing levels. From Eric Dumazet. 11) Reduce the number of get_page/put_page ops done on SKB fragments, from Alexander Duyck. 12) Implement protection against blind resets in TCP (RFC 5961), from Eric Dumazet. 13) Support the client side of TCP Fast Open, basically the ability to send data in the SYN exchange, from Yuchung Cheng. Basically, the sender queues up data with a sendmsg() call using MSG_FASTOPEN, then they do the connect() which emits the queued up fastopen data. 14) Avoid all the problems we get into in TCP when timers or PMTU events hit a locked socket. The TCP Small Queues changes added a tcp_release_cb() that allows us to queue work up to the release_sock() caller, and that's what we use here too. From Eric Dumazet. 15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1870 commits) genetlink: define lockdep_genl_is_held() when CONFIG_LOCKDEP r8169: revert "add byte queue limit support". ipv4: Change rt->rt_iif encoding. net: Make skb->skb_iif always track skb->dev ipv4: Prepare for change of rt->rt_iif encoding. ipv4: Remove all RTCF_DIRECTSRC handliing. ipv4: Really ignore ICMP address requests/replies. decnet: Don't set RTCF_DIRECTSRC. net/ipv4/ip_vti.c: Fix __rcu warnings detected by sparse. ipv4: Remove redundant assignment rds: set correct msg_namelen openvswitch: potential NULL deref in sample() tcp: dont drop MTU reduction indications bnx2x: Add new 57840 device IDs tcp: avoid oops in tcp_metrics and reset tcpm_stamp niu: Change niu_rbr_fill() to use unlikely() to check niu_rbr_add_page() return value niu: Fix to check for dma mapping errors. net: Fix references to out-of-scope variables in put_cmsg_compat() net: ethernet: davinci_emac: add pm_runtime support net: ethernet: davinci_emac: Remove unnecessary #include ...

This can happen with many macvlan devices attached to the PF or by adding many fdb entries in SR-IOV modes. Also this includes a small refactor to fdb_add() to avoid having so many nested if/else statements after adding a check for the number or RAR entries. The max entries for the PF is currently 16 we allow 15 additional entries to account for the defined MAC.

The main motivation for this change is to address possible bad configurations in which more TCs worth of data are populated then there are actual TCs. By limiting this value we can at least make certain we are not providing a map with values that are out of range. As a result any user priorities that are setup in the configuration with a traffic class mapping higher than what the hardware supports will be reported as being on TC 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent changes to netdev_alloc_skb actually make it so that the size of the buffer now actually has a more direct input on the truesize. So in order to make best use of the piece of a page we are allocated I am reducing the IXGBE_RX_HDR_SIZE to 256 so that our truesize will be reduced by 256 bytes as well. This should result in performance improvements since the number of uses per page should increase from 4 to 6 in the case of a 4K page.

| | * ixgbe: Fix handling of FDIR_HASH flagAlexander Duyck2012-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that we can use the atr_sample_rate to determine if we are capable of supporting ATR. The advantage to this approach is that it allows us to now determine the setting of the IXGBE_FLAG_FDIR_HASH_CAPABLE based on the queueing scheme, instead of the queueing scheme being based on the flag. Using this approach there are essentially 5 conditions that must be checked prior to trying to enable ATR: 1. Is SR-IOV disabled? 2. Are the number of TCs <= 1? 3. Is RSS queueing limit greater than 1? 4. Is atr_sample_rate set? 5. Is Flow Director perfect filtering disabled? If any of these conditions are enabled they should disable ATR filtering. Note that in the case of conditions 1 through 4 being met we will set things up for ATR queueing, however if test 5 fails we will still leave the queues allocated for use by perfect filters. The reason for this is to allow for us to switch back and forth between ntuple and ATR without needing to reallocate the descriptor rings.

| | * ixgbe: Change how we check for pre-existing and assigned VFsAlexander Duyck2012-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does two things. First it drops the unnecessary work of searching for enabled VFs when we first bring up the adapter and instead just uses pci_num_vf to determine how many VFs are enabled on the adapter. The second thing it does is drop the use of vfdev from the vf_data_storage structure. Instead we just search the entire system for a VF that has us as it's PF, and then if that VF is assigned we indicate that the VFs are assigned. This allows us to still check for assigned VFs even if the vfinfo allocation has failed, or vfinfo has been freed.

What happens now is that we always call ixgbe_enable_sriov and this checks for pre-existing VFs ore requested VFs prior to deciding on no SR-IOV.

Access to the vring and guest memory is typically only possible from vhost worker context so it is useful to allow work to be queued directly by users. Currently vhost_net only uses the poll wrappers which do not expose the work queue functions. However, for tcm_vhost (vhost_scsi) it will be necessary to queue custom work.
