Reported by Michael Guntsche <mike@it-loops.com> -------------------- Commit 38bddf04bcfe661fbdab94888c3b72c32f6873b3 gianfar: gfar_remove needs to call unregister_netdev() breaks the build of the gianfar driver because "dev" is undefined in this function.

2009-09-05mlx4_core: Distinguish multiple devices in /proc/interruptsArputham Benjamin1-8/+26
When the mlx4 driver uses the same name for interrupts for every device in the system. This can make it very confusing trying to work out exactly which device MSI-X interrupts are for.

But both those functions are also called from mlx4_close_hca(), which leads to a double free.

2009-09-05mlx4_core: Allocate and map sufficient ICM memory for EQ contextRoland Dreier3-51/+7
The current implementation allocates a single host page for EQ context memory, which was OK when we only allocated a few EQs. However, since we now allocate an EQ for each CPU core, this patch removes the hard-coded limit (which we exceed with 4 KB pages and 128 byte EQ context entries with 32 CPUs) and uses the same ICM table code as all other context tables, which ends up simplifying the code quite a bit while fixing the problem. This problem was actually hit in practice on a dual-socket Nehalem box with 16 real hardware threads and sufficiently odd ACPI tables that it shows on boot SMP: Allowing 32 CPUs, 16 hotplug CPUs so num_possible_cpus() ends up 32, and mlx4 ends up creating 33 MSI-X interrupts and 33 EQs. This mlx4 bug means that mlx4 can't even initialize at all on this quite mainstream system.

2009-09-01lsm: Add hooks to the TUN driverPaul Moore1-7/+15
The TUN driver lacks any LSM hooks which makes it difficult for LSM modules, such as SELinux, to enforce access controls on network traffic generated by TUN users; this is particularly problematic for virtualization apps such as QEMU and KVM. This patch adds three new LSM hooks designed to control the creation and attachment of TUN devices, the hooks are: * security_tun_dev_create() Provides access control for the creation of new TUN devices * security_tun_dev_post_create() Provides the ability to create the necessary socket LSM state for newly created TUN devices * security_tun_dev_attach() Provides access control for attaching to existing, persistent TUN devices and the ability to update the TUN device's socket LSM state as necessary Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: Eric Paris <eparis@parisplace.org> Acked-by: Serge Hallyn <serue@us.ibm.com> Acked-by: David S.

2009-08-28ipw2200: firmware DMA loading reworkZhu Yi1-53/+67
Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure for ipw2200 firmware loading in kernel 2.6.30. High order allocation is likely to fail and should always be avoided. The patch fixes this problem by replacing the original order-6 pci_alloc_consistent() with an array of order-1 pages from a pci pool. This utilized the ipw2200 DMA command blocks (up to 64 slots). The maximum firmware size support remains the same (64*8K).

2009-08-23drivers/net: fixed drivers that support netpoll use ndo_start_xmit()Dongdong Deng4-9/+13
The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of "A functions set" in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use "B functions set" to prevent the irqs from getting enabled while in netpoll_send_skb(). A functions set: local_irq_disable()/local_irq_enable() spin_lock_irq()/spin_unlock_irq() spin_trylock_irq()/spin_unlock_irq() B functions set: local_irq_save()/local_irq_restore() spin_lock_irqsave()/spin_unlock_irqrestore() spin_trylock_irqsave()/spin_unlock_irqrestore() Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.

2009-08-23E100: fix interaction with swiotlb on X86.Krzysztof Hałasa1-1/+1
E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

RTL8187B always needs MSR_LINK_ENEDCA flag to be set even when it is in no link mode, otherwise it'll not be able to associate when this flag is not set after the change "mac80211: fix managed mode BSSID handling". By accident, setting BSSID of AP before association makes 8187B to successfuly associate even when ENEDCA flag isn't set, which was the case before the mac80211 change. But now the BSSID of AP we are trying to associate is only available after association is successful, and any attempt to associate without the needed flag doesn't work.

2009-08-20ibm_newemac: emac_close() needs to call netif_carrier_off()Petri Gynther1-0/+2
When ibm_newemac netdev instance is shutdown with "ifconfig down", the netdev interface does not go properly down. netif_carrier_ok() keeps returning TRUE even after "ifconfig down". The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves. When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.

2009-08-13ixgbe: Do not return 0 in ixgbe_fcoe_ddp() upon FCP_RSP in DDP completionYi Zou1-1/+1
We return the ddp->len in ixgbe_fcoe_ddp() to indicate the length of data that have been DDPed. However, it is possible that the length is 0, e.g., for SCSI READ, the FCP_RSP may come back w/ SCSI status 0x28 as Task Set Full with no FCP data for DDP. In ixgbe_fcoe_ddp(), we return 0 to indicate not passing DDPed packets to upper layer. Therefore in the case of ddp->len being 0 upon FCP_RSP, we do not want to return the 0 ddp->len as we want FCP_RSP to be always delivered to the upper layer. This patch fixes this bug by setting rc only if ddp->len is non-zero.

2009-08-13netxen: free napi resources during detachDhananjay Phadke2-15/+24
o Defer napi resouce allocation to device attach. o Free napi resources and delete napi during detach. This ensures right behavior across firmware reset. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-13netxen: remove netxen workqueueAmit Kumar Salecha2-29/+42
o Remove private workqueue in the driver, move all scheduled tasks to keventd workqueues. This makes ports (interfaces) of same / different NIC boards independent, in terms of their link watchdog and reset tasks. o Move quick checks for link status and temperature in timer callback, schedule watchdog task only if link status changed or temperature reached critical threshold. This also fixes deadlock when thermal panic occurs, watchdog work was flushing workqueue that it was sitting on.

2009-08-13ixgbe: fix issues setting rx-usecs with legacy interruptsDon Skidmore1-8/+19
Currently setting rx-usecs when the interface is in legacy interrupt mode it is not immediate. We were only setting EITR for each MSIx vector and since this count would be zero for legacy mode it wasn't set until after a reset. This patch corrects that by checking what mode we are in and then setting EITR accordingly.

2009-08-13can: fix oops caused by wrong rtnl newlink usageOliver Hartkopp1-0/+7
For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created with the ip tool ... The invocation of 'ip link add type can' lead to an oops as the standard rtnl newlink function was called: http://bugzilla.kernel.org/show_bug.cgi?id=13954 This patch adds a private newlink function for the CAN device driver interface that unconditionally returns -EOPNOTSUPP.
