* USB: add missing KERN_* constants to printksFrank Seidel2009-03-24
| | | | | | | | | | According to kerneljanitors todo list all printk calls (beginning a new line) should have an according KERN_* constant. Those are the missing peaces here for the usb subsystem. Signed-off-by: Frank Seidel <frank@f-seidel.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: serial generic resume function fixOliver Neukum2009-03-24
| | | | | | | | | | | | This removes an unnecessary check for autoresume from the generic resume method. The check has been obsoleted by the now delayed increase of the usage counter which makes the error this check prevented impossible. This change allows drivers which only use the bulk read URB the use of the generic method even if they support autosuspend.

* USB: pxa27x_udc: add vbus_draw callbackRobert Jarzmik2009-03-24
| | | | | | | | | | | | | | | Add the vbus_draw() callback to inform the transceiver, if it exists, how much current may be drawn. The decision is taken on gadget driver side using the configuration chosen by the host and its bMaxPower field. Some systems can use the host's VBUS supply to augment or recharge a battery. (There's also a default of 100 mA for unconfigured devices, or 8 mA if they're OTG devices.)

* usblp: continuously poll for statusPete Zaitcev2009-03-24
| | | | | | | | | | | | | | | | The usblp in 2.6.18 polled for status regardless if we actually needed it. At some point I dropped it, to save the batteries if nothing else. As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding this way or else they stop. This patch restores the old behaviour. If you want to save battery, don't leave jobs in the print queue. I tested this on my printers by printing and examining usbmon traces to make sure status is being requested and printers continue to print. Tuomas Jäntti verified the fix on BJC-3000.

* USB: usb-storage: increase max_sectors for tape drivesAlan Stern2009-03-24
| | | | | | | | | | | | | | | | This patch (as1203) increases the max_sector limit for USB tape drives. By default usb-storage sets max_sectors to 240 (i.e., 120 KB) for all devices. But tape drives need a higher limit, since tapes can and do have very large block sizes. Without the ability to transfer an entire large block in a single command, such tapes can't be used. This fixes Bugzilla #12207.

* USB: gadget: fix rndis regressionDavid Brownell2009-03-24
| | | | | | | | | | | | | | | | | | | | Restore some code that was wrongly dropped from the RNDIS driver, and caused interop problems observed with OpenMoko. The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it. But we do need to tell the UDC when it must force a short packet termination of the data stage. (Based on a patch from Aric D.

* USB: add quirk to avoid config and interface stringsAlan Stern2009-03-24
| | | | | | | | | | | | | | | | | | | Apparently the Configuration and Interface strings aren't used as often as the Vendor, Product, and Serial strings. In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests. This patch (as1226) adds a quirks flag, telling the kernel not to read a device's Configuration or Interface strings, together with a new quirk for the offending joystick.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

| * dm9000: locking bugfixDavid Brownell2009-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

| * tulip: fix crash on iface up with shirq debugKyle McMartin2009-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tulip is currently doing request_irq before it has done its initialization. This is usually not a problem because it hasn't enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler when registering the interrupt as a sanity check. This can result in a NULL ptr dereference, so call tulip_init_ring before request_irq, and add a free_ring function to do the freeing now shared with tulip_close. Tested with a shell loop running ifup, ifdown in a loop a few hundred times with DEBUG_SHIRQ on. Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * virtio_net: Make virtio_net support carrier detectionPantelis Koukousoulas2009-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Make NetworkManager work with virtio_net For now the semantics are simple: There is always carrier. This allows a seamless experience with e.g., qemu/kvm where NetworkManager just configures and sets up everything automagically. If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects an omission from the following commit: commit f0c76d61779b153dbfb955db3f144c62d02173c2 Author: Jay Vosburgh <fubar@us.ibm.com> Date: Wed Jul 2 18:21:58 2008 -0700 bonding: refactor mii monitor The un-refactored code checked the link speed and duplex of every slave on every pass; the refactored code did not do so. The 802.3ad and balance-alb/tlb modes utilize the speed and duplex information, and require it to be kept up to date. This patch adds a notifier check to perform the appropriate updating when the slave device speed changes. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

| * bnx2: Fix problem of using wrong IRQ handler.Michael Chan2009-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSI-X handler was chosen before the call to pci_enable_msix(). If MSI-X was not available, the wrong MSI-X handler would be used in INTA mode. This would cause a screaming interrupt problem because INTA would not be cleared by the MSI-X handler. Fixed by assigning MSI-X handler after pci_enable_msix() returns successfully. Also update version to 1.9.3. Thomas Chenault <thomas_chenault@dell.com> helped us find this problem.

| | | | | | | | | | | | | | | | | | | | | | zd_op_tx() must not return an arbitrary error value since that can leave mac80211 trying to retransmit the frame and with the extra data pushed into the beginning of the skb on every attempt, this will end up causing a kernel panic (skb_under_panic from skb_push call).

PCI express devices not not require this. This should fix our only last standing open ath9k kernel.org bugzilla bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12110 A port is probably required to older kernels and I can work on that.

The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.
