2009-03-24usb-storage: prepare for subdriver separationAlan Stern9-134/+257
This patch (as1206) is the first step in converting usb-storage's subdrivers into separate modules. It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions.

2009-03-24usb-serial: fix usb_serial_register bug when boot with nousb paramDave Young1-0/+3
With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it. Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-03-24USB: EHCI: add software retry for transaction errorsAlan Stern2-0/+35
This patch (as1204) adds a software retry mechanism to ehci-hcd. It gets invoked when the driver encounters transaction errors on an asynchronous endpoint. On many systems, hardware deficiencies cause such errors to occur if one device is unplugged while the host is communicating with another device. With the patch, the failed transactions are retried and generally succeed the second or third time through. This is based on code originally written by Koichiro Saito.

commit 64a87b24: [SCSI] Let scsi_cmnd->cmnd use request->cmd buffer changed the scsi_eh_prep_cmnd logic by making it clear the ->cmnd buffer.

The problem and a fix was reported by Matthieu CASTET <castet.matthieu@free.fr> It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer, which is much more suitable a buffer for HW transfers, then after the command execution the regs read is copied into regs buffer before actual preparation of sense_buffer.

2009-03-24USB: serial: refuse to open recently removed USB Serial devicesJames Woodcock1-0/+5
A USB-serial converter device is plugged into a system, and a process opens it's device node. If the device is physically removed whilst the process still has its device node open, then other processes can sucessfully open the now non-existent device's node. I would expect that open() on a device that has been physically removed should return ENODEV. This is manifesting itself with getty on my system. I do the following: 1. set up inittab to spawn getty on ttyUSB0, eg: T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100 2. Plug in USB-serial converter cable 3. Wait for a login prompt on a terminal program attached to the serial cable 4. Login 5. Pull the USB-serial converter cable from the box 6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0 can still be opened. 7. Re-insert the USB-serial converter cable 8. You should no longer get a login prompt over the serial cable, as the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is trying to talk to /dev/ttyUSB0. The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return ENODEV after the USB-serial converter has been pulled. The patch was created against 2.6.28.1. I can supply it against something else if needs be. It is fairly simple, so should be OK. I am using a pl2303 device, although I don't think that makes any difference.

If you want to save battery, don't leave jobs in the print queue.

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.

2009-03-24USB: gadget: fix rndis regressionDavid Brownell1-1/+1
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. Blumer <aric at sdgsystems.com>) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-03-24USB: add quirk to avoid config and interface stringsAlan Stern3-2/+9
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.

commit b1c4a9dddf09fe99b8f88252718ac5b357363dc4 ("ucc_geth: Change uec phy id to the same format as gianfar's") introduced a regression in the ucc_geth driver that causes this oops when fixed-link is used: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc0151270 Oops: Kernel access of bad area, sig: 11 [#1] TMCUTU NIP: c0151270 LR: c0151270 CTR: c0017760 REGS: cf81fa60 TRAP: 0300 Not tainted (2.6.29-rc8) MSR: 00009032 <EE,ME,IR,DR> CR: 24024042 XER: 20000000 DAR: 00000000, DSISR: 20000000 TASK = cf81cba0[1] 'swapper' THREAD: cf81e000 GPR00: c0151270 cf81fb10 cf81cba0 00000000 c0272e20 c025f354 00001e80 cf86b08c GPR08: d1068200 cffffb74 06000000 d106c200 42024042 10085148 0fffd000 0ffc81a0 GPR16: 00000001 00000001 00000000 007ffeb0 00000000 0000c000 cf83f36c cf83f000 GPR24: 00000030 cf83f360 cf81fb20 00000000 d106c200 20000000 00001e80 cf83f360 NIP [c0151270] ucc_geth_open+0x330/0x1efc LR [c0151270] ucc_geth_open+0x330/0x1efc Call Trace: [cf81fb10] [c0151270] ucc_geth_open+0x330/0x1efc (unreliable) [cf81fba0] [c0187638] dev_open+0xbc/0x12c [cf81fbc0] [c0187e38] dev_change_flags+0x8c/0x1b0 This patch fixes the issue by removing offending (and somewhat duplicate) code from init_phy() routine, and changes _probe() function to use uec_mdio_bus_name(). 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.
