2010-04-28Revert "tcp: bind() fix when many ports are bound"David S. Miller2-21/+10
This reverts two commits: fda48a0d7a8412cedacda46a9c0bf8ef9cd13559 tcp: bind() fix when many ports are bound and a follow-on fix for it: 6443bb1fc2050ca2b6585a3fa77f7833b55329ed ipv6: Fix inet6_csk_bind_conflict() It causes problems with binding listening sockets when time-wait sockets from a previous instance still are alive. It's too late to keep fiddling with this so late in the -rc series, and we'll deal with it in net-next-2.6 instead. Signed-off-by: David S. Miller <[email protected]>
2010-04-28nfs: fix memory leak in nfs_get_sb with CONFIG_NFS_V4Xiaotian Feng1-0/+1
With CONFIG_NFS_V4 and data version 4, nfs_get_sb will allocate memory for export_path in nfs4_validate_text_mount_data, so we need to free it then.

2010-04-28x86/PCI: compute Address Space length rather than using _LENBjorn Helgaas1-38/+2
ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <[email protected]> Signed-off-by: Jesse Barnes <[email protected]>

2010-04-28drivers/gpu/drm/drm_sysfs.c: sysfs files error handlingDan Carpenter1-9/+12
In the original code we used "j" as an iterator but we used "i" as an index. - for (j = 0; j < i; j++) - device_remove_file(&connector->kdev, - &connector_attrs[i]); Smatch complained about that because "i" was potentially passed the end of the array. Which makes sense if we should be using "j" there. I also thought that we should remove the files for &connector_attrs_opt1 but to do that I had to add separate iterators for &connector_attrs and &connector_attrs_opt1.

Firmware changed the way it represents memory and cpu affinity on POWER7. Unfortunately the old method now caps the topology to work around issues with legacy operating systems. For Linux to get the correct topology we need to use the new form 1 affinity information. We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array. If not we use the second field as we always have. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2010-04-27net/usb: add sierra_net.c driverElina Pasheva3-0/+1012
Re-submitted based on comments from netdev community. Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

2010-04-27keys: the request_key() syscall should link an existing key to the dest keyringDavid Howells1-1/+8
The request_key() system call and request_key_and_link() should make a link from an existing key to the destination keyring (if supplied), not just from a new key to the destination keyring. This can be tested by: ring=`keyctl newring fred @s` keyctl request2 user debug:a a keyctl request user debug:a $ring keyctl list $ring If it says: keyring is empty then it didn't work. If it shows something like: 1 key in keyring: 1070462727: --alswrv 0 0 user: debug:a then it did. request_key() system call is meant to recursively search all your keyrings for the key you desire, and, optionally, if it doesn't exist, call out to userspace to create one for you. If request_key() finds or creates a key, it should, optionally, create a link to that key from the destination keyring specified. Therefore, if, after a successful call to request_key() with a desination keyring specified, you see the destination keyring empty, the code didn't work correctly. If you see the found key in the keyring, then it did - which is what the patch is required for.

2010-04-27gpio: fix pca953x set_type 'scheduling while atomic' bugMarc Zyngier1-1/+13
Bill Gatliff reported the following bug when using the irq_chip facility of the pca953x driver on a PPC platform: BUG: scheduling while atomic: insmod/1530/0x00000002 He traced it back to an i2c transaction in pca953x_irq_set_type(), which can be called with interrupt disabled (from __setup_irq()). As the i2c controller can sleep while sending a message, this qualifies as a bad idea. This patch moves the i2c transaction to pca953x_irq_bus_sync_unlock(), where it is actually safe to send an i2c message.

2010-04-27bnx2: Prevent "scheduling while atomic" warning with cnic, bonding and vlan.Michael Chan1-18/+20
The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

2010-04-27bnx2: Fix lost MSI-X problem on 5709 NICs.Michael Chan1-1/+5
It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

2010-04-27e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errataBruce Allan3-40/+55
Prompted by a previous patch submitted by Matthew Garret <[email protected]>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

2010-04-27ixgbe: Power down PHY during driver resetsPeter Waskiewicz3-24/+62

Power down the laser while setting up the device, and re-enable the laser before getting link.
