2011-08-20atm: br2684: Fix oops due to skb->dev being NULLDaniel Schwierzeck1-3/+4
This oops have been already fixed with commit 27141666b69f535a4d63d7bc6d9e84ee5032f82a atm: [br2684] Fix oops due to skb->dev being NULL It happens that if a packet arrives in a VC between the call to open it on the hardware and the call to change the backend to br2684, br2684_regvcc processes the packet and oopses dereferencing skb->dev because it is NULL before the call to br2684_push(). but have been introduced again with commit b6211ae7f2e56837c6a4849316396d1535606e90 atm: Use SKB queue and list helpers instead of doing it by-hand.

2011-08-18vlan: reset headers on accel emulation pathJiri Pirko1-0/+2
It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected.

2011-08-17bonding:reset backup and inactive flag of slavePeter Pan(潘卫平)1-0/+18
Eduard Sinelnikov ([email protected]) found that if we change bonding mode from active backup to round robin, some slaves are still keeping "backup", and won't transmit packets. As Jay Vosburgh([email protected]) pointed out that we can work around that by removing the bond_is_active_slave() check, because the "backup" flag is only meaningful for active backup mode. But if we just simply ignore the bond_is_active_slave() check, the transmission will work fine, but we can't maintain the correct value of "backup" flag for each slaves, though it is meaningless for other mode than active backup. I'd like to reset "backup" and "inactive" flag in bond_open, thus we can keep the correct value of them. As for bond_is_active_slave(), I'd like to prepare another patch to handle it. V2: Use C style comment. Move read_lock(&bond->curr_slave_lock). Replace restore with reset, for active backup mode, it means "restore", but for other modes, it means "reset".

2011-08-16sit tunnels: propagate IPv6 transport class to IPv4 Type of ServiceLionel Elie Mamane1-0/+3
sit tunnels (IPv6 tunnel over IPv4) do not implement the "tos inherit" case to copy the IPv6 transport class byte from the inner packet to the IPv4 type of service byte in the outer packet. By contrast, ipip tunnels and GRE tunnels do. This patch, adapted from the similar code in net/ipv4/ipip.c and net/ipv4/ip_gre.c, implements that.

2011-08-13drivers/net/can/sja1000/plx_pci.c: eliminate double freeJulia Lawall1-2/+2
In this code, the failure_cleanup label calls the function plx_pci_del_card, which frees everything in the card->net_dev array. dev is placed in this array immediately after allocation, so the two subsequent jumps to failure_cleanup should not also call free_sja1000dev, but the second one does. If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on dev. Because dev is already in the card->net_dev array, this implies that when plx_pci_del_card is later called, it may get freed again. So that entry is reset to NULL after the free. Finally, if there is a problem with one channel, there will be a hole in the array. card->channels counts the number of channels that have succeeded, and does not keep track of the index of the largest element in the array that is valid. So the loop in plx_pci_del_card is changed to go up to PLX_PCI_MAX_CHAN, which is only 2. Signed-off-by: Julia Lawall <[email protected]> Signed-off-by: David S. Miller <[email protected]>

The vmxnet3 driver enables vlan filters if filtering is enabled for any vlan. In promiscuous mode the filter table is cleared to in order to disable filtering. However, if a vlan device is subsequently created that vlan will be added to the filter, re-engaging it. As a result, not only do we not see all the vlans in promiscuous mode, we don't even see vlans for which a filter was previously created. CC: Scott J.

2011-08-13e1000e: workaround invalid Tx/Rx tail descriptor register writeBruce Allan3-4/+85
When the Manageability Engine (ME) is enabled on 82579, it periodically accesses some MAC CSR registers. There is an arbiter in hardware which prevents simultaneous access of these registers by the host software, i.e. the driver. There is a hardware bug in the aribter that signals a host access of the registers later than it actually happens. A write of the Transmit or Receive Descriptor Tail register could result in an incorrect value if the driver and ME perform simultaneous accesses which could result in an access to an invalid memory address. This would return an Unsupported Request which could hang the hardware. Workaround the issue by checking the FWSM register bit24 which is set by ME before it accesses the MAC CSR registers.

The MAC can drop short packets when the PHY detects noise on the line at 100Mbps due to a timing issue.

2011-08-13e1000e: Spurious interrupts & dropped packets with 82577/8/9 in half-duplexBruce Allan1-8/+33
On 82577/8/9 in half-duplex when a received packet is passed from the PHY to the MAC, if too many preamble octects are stripped from the packet before arriving at the MAC, it can be misintrepeted as an in-band message rather than an actual frame. For example, if the frame contents resembled an interrupt request in-band message, it would trigger a false interrupt. In most cases, the packet is just dropped. By reducing the number of preamble octets stripped from the beginning of the frame when passing it from the PHY to the MAC, the MAC will interpret the frame properly. An additional uses of the magic PHY_REG(770, 16) have been updated with a define introduced with this patch.

Just like files-layout, blocks & objects layouts are part of the NFS 4.1 protocol and should be automatically selected if NFS_4_1 is selected. The small problem is that these depend on other Kernel support being present, while files only depends on NFS itself. This patch removes from the user choice the presence of objects and blocks layout. But makes sure these are selected only if the depended subsystems are present in the Kernel.

In rt2800usb_work_txdone we check flags in order: - ENTRY_OWNER_DEVICE_DATA - ENTRY_DATA_STATUS_PENDING - ENTRY_DATA_IO_FAILED Modify flags in separate order in rt2x00usb_interrupt_txdone, to avoid processing entries in _txdone with wrong flags or skip processing ready entries.
