This reverts commit eb6b9a8c. Above commit limits GSO capability of gre device to just TSO, but software GRE-GSO is capable of handling all GSO capabilities. This patch also fixes following panic which reverted commit introduced:- BUG: unable to handle kernel NULL pointer dereference at 00000000000000a2 IP: [<ffffffffa0680fd1>] ipgre_tunnel_bind_dev+0x161/0x1f0 [ip_gre] PGD 42bc19067 PUD 42bca9067 PMD 0 Oops: 0000 [#1] SMP Pid: 2636, comm: ip Tainted: GF 3.8.0+ #83 Dell Inc.

commit "ip_gre: allow CSUM capable devices to handle packets" aa0e51cd, broke GRE_CSUM case. GRE_CSUM needs checksum computed for inner packet. Therefore csum-calculation can not be offloaded if tunnel device requires GRE_CSUM. Following patch fixes it by computing inner packet checksum for GRE_CSUM type, for all other type of GRE devices csum is offloaded. CC: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by:

Noticed that vmxnet3's get_ringparam function was returning the summation of all ring buffers on a NIC, rather than just the size of any one ring. This causes problems when a vmxnet3 instance has multiple queues, as ethtool, when setting ring parameters, first gets the current ring parameters to set the existing values in the set_ringparm commannd. The result is, that unless both rx and tx ring sizes are set in a single operation, which ever ring is not set will silently have its ring count multiplied by the number of queues on the NIC until it reaches a driver defined maxiumum value. Fix it by not multiplying the rx and tx ring sizes by the number of queues in the system, like every other driver. Tested by myself successfully. Signed-off-by:

Commit ee873fda ("gianfar: Pack struct gfar_priv_grp into three cachelines") moved the irq number and names off into a separate struct and created accessors for them. However it was never tested with NET_POLL enabled, and so some conversions that were simply overlooked went undetected until now. Make the netpoll ones also use the gfar_irq() accessors. Reported-by:

There are two places to call vlan_set_encap_proto(): vlan_untag() and __pop_vlan_tci(). vlan_untag() assumes skb->data points after mac addr, otherwise the following code vhdr = (struct vlan_hdr *) skb->data; vlan_tci = ntohs(vhdr->h_vlan_TCI); __vlan_hwaccel_put_tag(skb, vlan_tci); skb_pull_rcsum(skb, VLAN_HLEN); won't be correct. But __pop_vlan_tci() assumes points _before_ mac addr. In vlan_set_encap_proto(), it looks for some magic L2 value after mac addr: rawp = skb->data; if (*(unsigned short *) rawp == 0xFFFF) ... Therefore __pop_vlan_tci() is obviously wrong. A quick fix is avoiding using skb->data in vlan_set_encap_proto(), use 'vhdr+1' is always correct in both cases. Cc: David S.

Kleber Sacilotto de Souza authored
The mlx4_en driver allocates the number of objects for the CPU affinity reverse-map based on the number of rx rings of the device. However, mlx4_assign_eq() calls irq_cpu_rmap_add() as many times as IRQ's are assigned to EQ's, which can be as large as mlx4_dev->caps.comp_pool. If caps.comp_pool is larger than rx_ring_num we will eventually hit the BUG_ON() in cpu_rmap_add(). Fix this problem by allocating space for the maximum number of CPU affinity reverse-map objects we might want to add. Signed-off-by:

The memory to hold the network device tx_cq is not being allocated with the correct size in mlx4_en_init_netdev(). It should use MAX_TX_RINGS instead of MAX_RX_RINGS. This can cause problems if the number of tx rings being used is greater than MAX_RX_RINGS. Signed-off-by:

In fast open the sender unncessarily reduces the space available for data in SYN by 12 bytes. This is because in the sender incorrectly reserves space for TS option twice in tcp_send_syn_data(): tcp_mtu_to_mss() already accounts for TS option space. But it further reserves MAX_TCP_OPTION_SPACE when computing the payload space. Signed-off-by:

Unload sequence for mwifiex PCIE driver is as follows: 1. Invoking cleanup module from kernel results into pci_unregister_driver 2. Kernel invokes PCIE remove() handler which disconnects all interfaces. 3. One step during disconnect is to clean PCIE TX rings. During this we read txbd_rdptr from FW. While loading driver next time, we see pci_enable_device() results into system freeze. This may have happened because we accessed PCI device after unregistering from bus driver. Removing this ioread() operation resolves this bug. Signed-off-by:

It looks like its possible to open thousands of TCP IPv6 sessions on a server, all landing in a single slot of TCP hash table. Incoming packets have to lookup sockets in a very long list. We should hash all bits from foreign IPv6 addresses, using a salt and hash mix, not a simple XOR. inet6_ehashfn() can also separately use the ports, instead of xoring them. Reported-by:

Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

I'm not convinced with the primary arguments for this, but it's been around for a while, and people seem happy with it - and the "other" justification for this is at http://lkml.org/lkml/2012/12/6/184 - Add SCHED_HRTICK to ARMs Kconfig - Making the ARM SHA/AES code Thumb-2 compatible - A collection of other small updates. * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (26 commits) ARM: add SCHED_HRTICK config option ARM: 7650/1: mm: replace direct access to mm->context.id with new macro ARM: 7649/1: mm: mm->context.id fix for big-endian ARM: 7648/1: pci: Allow passing per-controller private data ARM: 7647/1: pci: Keep pci_common_init() around after init ARM: fix warnings introduced by previous patch ARM: 7646/1: mm: use static_vm for managing static mapped areas ARM: 7645/1: ioremap: introduce an infrastructure for static mapped area ARM: 7644/1: vmregion: remove vmregion code entirely MAINTAINERS: Re-assert MMCI driver maintainer status MAINTAINERS: add additional file for MMCI driver MAINTAINERS: add maintainer entry for AMBA serial drivers ARM: 7637/1: memory: use SZ_ constants for defining the virtual memory layout ARM: 7643/1: sched: correct update_sched_clock() ARM: 7635/1: versatile: fix the PCI IRQ regression ARM: 7639/1: cache-l2x0: add missed dummy outer_resume entry ARM: 7630/1: mmc: mmci: Fixup and cleanup code for DMA handling ARM: 7632/1: spinlock: avoid exclusive accesses on unlock() path ARM: 7631/1: mmc: mmci: Add new VE MMCI variant ARM: 7623/1: mmc: mmci: Fixup clock gating when freq is 0 for ST-variants ... -

Introduce a common smp_callin() function to call from trampoline_32.S. Add platform specific functions to handle the platform details. This is in preparation for a patch that will unify the smp boot stuff for all architectures. sparc32 was significantly different to warrant this patch in preparation. Signed-off-by:

When we set the sun4u version of the PTE execute bit, it's: or REG, _PAGE_EXEC_4U, REG _PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the 'or' instruction is a signed 13-bit value. So the above actually assembles into: or REG, -4096, REG completely corrupting the final PTE value. Set it with a: sethi %hi(_PAGE_EXEC_4U), TMP or REG, TMP, REG sequence instead. This fixes "git gc" crashes on sun4u machines. Reported-by:
