2010-09-10sfc: Allow changing the DMA ring sizes dynamically via ethtoolBen Hutchings5-52/+224

2010-09-10sfc: Allocate DMA and event rings using GFP_KERNELBen Hutchings1-4/+4
Currently we allocate DMA descriptor rings and event rings using pci_alloc_consistent() which selects non-blocking behaviour from the page allocator (GFP_ATOMIC). This is unnecessary, and since we currently allocate a single contiguous block for each ring (up to 32 pages!) these allocations are likely to fail if there is any significant memory pressure. Use dma_alloc_coherent() and GFP_KERNEL instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-10sfc: Accumulate RX_NODESC_DROP count in rx_dropped, not rx_over_errorsBen Hutchings1-1/+1
rx_over_errors appears to be intended as a count of packets that overflow a packet buffer in the NIC. Given that we implement a cut-through receive path, this should always be 0. rx_dropped appears to be the correct counter for packets dropped due to lack of host buffers.

2010-09-10sfc: Use MCDI RX_BAD_FCS_PKTS count as MAC rx_bad countBen Hutchings1-1/+1

2010-09-10ipheth: remove incorrect devtype to WWANDan Williams1-6/+1
The 'wwan' devtype is meant for devices that require preconfiguration and *every* time setup before the ethernet interface can be used, like cellular modems which require a series of setup commands on serial ports or other mechanisms before the ethernet interface will handle packets. As ipheth only requires one-per-hotplug pairing setup with no preconfiguration (like APN, phone #, etc) and the network interface is usable at any time after that initial setup, remove the incorrect devtype wwan.

2010-09-09ixgbe: fix TX ring enable issues seen when VMDQ is enabledAlexander Duyck1-1/+1
The ordering of operations was messed up in the init and as a result when VMDQ was enabled we were trying to enable TX rings before setting the VFTE bits. This resulted in a ring that appeared to fail to enable when in fact it was blocked because the VFTE bits were cleared after the reset.

2010-09-09e1000: fix Tx hangs by disabling 64-bit DMAJesse Brandeburg1-70/+92
Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO.

2010-09-09niu: Fix kernel buffer overflow for ETHTOOL_GRXCLSRLALLBen Hutchings1-10/+6
niu_get_ethtool_tcam_all() assumes that its output buffer is the right size, and warns before returning if it is not. However, the output buffer size is under user control and ETHTOOL_GRXCLSRLALL is an unprivileged ethtool command. Therefore this is at least a local denial-of-service vulnerability. Change it to check before writing each entry and to return an error if the buffer is already full. Compile-tested only.

2010-09-09introduce cx82310_eth: Conexant CX82310-based ADSL router USB ethernet driverOndrej Zary3-0/+363
This patch introduces cx82310_eth driver - driver for USB ethernet port of ADSL routers based on Conexant CX82310 chips. Such routers usually have ethernet port(s) too which are bridged together with the USB ethernet port, allowing the USB-connected machine to communicate to the network (and also internet through the ADSL, of course). This is my first driver, so please check thoroughly. As there's no protocol documentation, it was done with usbsnoop dumps from Windows driver, some parts (the commands) inspired by cxacru driver and also other usbnet drivers. The driver passed my testing - some real work and also pings sized from 0 to 65507 B. The only problem I found is the ifconfig error counter. When I return 0 (or 1 but empty skb) from rx_fixup(), usbnet increases the error counter although it's not an error condition (because packets can cross URB boundaries). Maybe the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some other value, e.g. 2)? The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems using cxacru driver (they probably use the same chipset but simpler firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The driver matches only devices with class 255 and checks for the iProduct string during init. I already posted a patch for the cxacru driver to ignore these devices.

2010-09-083c59x: Fix deadlock in vortex_error()Ben Hutchings1-3/+7
This fixes a bug introduced in commit de847272149365363a6043a963a6f42fb91566e2 "3c59x: Use fine-grained locks for MII and windowed register access". vortex_interrupt() holds vp->window_lock over multiple register accesses to reduce locking overhead. However it also needs to call vortex_error() sometimes, and that uses the regular functions for access to windowed registers, which will try to acquire window_lock again. Therefore, drop window_lock around the call to vortex_error() and set the window afterward reacquiring the lock. Since vortex_error() may call vortex_rx(), which *does* require its caller to hold window_lock, lift that call up into vortex_interrupt(). This also removes the potential for calling vortex_rx() on a later-generation NIC.

2010-09-08bonding: Fix jiffies overflow problems (again)Jiri Bohac1-17/+39
The time_before_eq()/time_after_eq() functions operate on unsigned long and only work if the difference between the two compared values is smaller than half the range of unsigned long (31 bits on i386). Some of the variables (slave->jiffies, dev->trans_start, dev->last_rx) used by bonding store a copy of jiffies and may not be updated for a long time. With HZ=1000, time_before_eq()/time_after_eq() will start giving bad results after ~25 days. jiffies will never be before slave->jiffies, dev->trans_start, dev->last_rx by more than possibly a couple ticks caused by preemption of this code. This allows us to detect/prevent these overflows by replacing time_before_eq()/time_after_eq() with time_in_range().
