2008-07-22modules: Take a shortcut for checking if an address is in a moduleRusty Russell
This patch keeps track of the boundaries of module allocation, in order to speed up module_text_address(). Inspired by Arjan's version, which required arch-specific defines: Various pieces of the kernel (lockdep, latencytop, etc) tend to store backtraces, sometimes at a relatively high frequency. In itself this isn't a big performance deal (after all you're using diagnostics features), but there have been some complaints from people who have over 100 modules loaded that this is a tad too slow. This is due to the new backtracer code which looks at every slot on the stack to see if it's a kernel/module text address, so that's 1024 slots. 1024 times 100 modules... that's a lot of list walking.

2008-07-22module: turn longs into ints for module sizesDenys Vlasenko
This shrinks module.o and each *.ko file. And finally, structure members which hold length of module code (four such members there) and count of symbols are converted from longs to ints. We cannot possibly have a module where 32 bits won't be enough to hold such counts. For one, module loading checks module size for sanity before loading, so such insanely big module will fail that test first.

2008-07-22Shrink struct module: CONFIG_UNUSED_SYMBOLS ifdefsDenys Vlasenko
module.c and module.h conatains code for finding exported symbols which are declared with EXPORT_UNUSED_SYMBOL, and this code is compiled in even if CONFIG_UNUSED_SYMBOLS is not set and thus there can be no EXPORT_UNUSED_SYMBOLs in modules anyway (because EXPORT_UNUSED_SYMBOL(x) are compiled out to nothing then).

2008-07-22module: don't use stop_machine for waiting rmmodRusty Russell
rmmod has a little-used "-w" option, meaning that instead of failing if the module is in use, it should block until the module becomes unused. In this case, we don't need to use stop_machine: Max Krasnyansky indicated that would be useful for SystemTap which loads/unloads new modules frequently.

2008-07-21usb-storage: revert DMA-alignment change for Wireless USBAlan Stern
This patch (as1110) reverts an earlier patch meant to help with Wireless USB host controllers. These controllers can have bulk maxpacket values larger than 512, which puts unusual constraints on the sizes of scatter-gather list elements. However it turns out that the block layer does not provide the support we need to enforce these constraints; merely changing the DMA alignment mask doesn't help. Hence there's no reason to keep the original patch. The Wireless USB problem will have to be solved a different way. In addition, there is a reason to get rid of the earlier patch. By dereferencing a pointer stored in the ep_in array of struct usb_device, the current code risks an invalid memory access when it runs concurrently with device removal. The members of that array are cleared before the driver's disconnect method is called, so it should not try to use them.

2008-07-21USB: use reset_resume when normal resume failsAlan Stern
This patch (as1109b) makes USB-Persist more resilient to errors. With the current code, if a normal resume fails, it's an unrecoverable error. With the patch, if a normal resume fails (and if the device is enabled for USB-Persist) then a reset-resume is tried. This fixes the problem reported in Bugzilla #10977.

2008-07-21USB: Fix pointer/int cast in USB devio codeDavid Howells
Fix pointer/int cast in USB devio code, and thus avoid a compiler warning. A void* data argument passed to bus_find_device() and thence to match_devt() is used to carry a 32-bit datum. However, casting directly between a u32 and a pointer is not permitted - there must be an intermediate cast via (unsigned) long. This was introduced by the following patch: commit 94b1c9fa060ece2c8f080583beb6cc6008e41413 Author: Alan Stern <stern@rowland.harvard.edu> Date: Tue Jun 24 14:47:12 2008 -0400 usbfs: simplify the lookup-by-minor routines This patch (as1105) simplifies the lookup-by-minor-number code in usbfs.

2008-07-21usbfs: don't store bad pointers in registrationAlan Stern
This patch (as1107) fixes a small bug in the usbfs registration and unregistration code.

2008-07-21usbfs: fix race between open and unregisterAlan Stern
This patch (as1106) fixes a race between opening and unregistering device files in usbfs. The current code drops its reference to the device and then reacquires it, ignoring the possibility that the device structure might have been removed in the meantime. It also doesn't check whether the device is already in the NOTATTACHED state when the file is opened.

2008-07-21usbfs: send disconnect signals when device is unregisteredAlan Stern
USB device files are accessible in two ways: as files in usbfs and as character device nodes. The two paths are supposed to behave identically, but they don't. When the underlying USB device is unplugged, disconnect signals are sent to processes with open usbfs files (if they requested these signals) but not to processes with open device node files. This patch (as1104) fixes the bug by moving the disconnect-signalling code into a common subroutine which is called from both paths. Putting this subroutine in devio.c removes the only out-of-file reference to struct dev_state, and so the structure's declaration can be moved from usb.h into devio.c. Finally, the new subroutine performs one extra action: It kills all the outstanding async URBs. (I'd kill the outstanding synchronous URBs too, if there was any way to do it.) In the past this hasn't mattered much, because devices were unregistered from usbfs only when they were disconnected. But now the unregistration can also occur whenever devices are unbound from the usb_generic driver. At any rate, killing URBs when a device is unregistered from usbfs seems like a good thing to do.

2008-07-21USB: Force unbinding of drivers lacking reset_resume or other methodsAlan Stern
This patch (as1024) takes care of a FIXME issue: Drivers that don't have the necessary suspend, resume, reset_resume, pre_reset, or post_reset methods will be unbound and their interface reprobed when one of the unsupported events occurs. This is made slightly more difficult by the fact that bind operations won't work during a system sleep transition. So instead the code has to defer the operation until the transition ends.

2008-07-21USB: ohci-pnx4008: I2C cleanups and fixesJean Delvare
Various cleanups and fixes to the i2c code in ohci-pnx4008: * Delete empty isp1301_command. The i2c driver command implementation is optional, so there's no point in providing an empty implementation. * Give a name to isp1301_driver. I'm surprised that i2c-core accepted to register this driver at all. I've chosen "isp1301_pnx" as the name, because it's not a generic ISP1301 driver (much like the isp1301_omap driver.) We might want to make the name even more specific (but "isp1301_ohci_pnx4008" doesn't fit.) * The ISP1301 is definitely not a hardware monitoring device. * Fix a memory leak on failure in isp1301_attach. If i2c_attach_client fails, the client is not registered so isp1301_detach is never called and the i2c_client memory is lost. * Use strlcpy instead of strcpy.

2008-07-21USB: debug port converter does not accept more than 8 byte packetsAleksey Gorelov
USB debug port only supports 8 byte rx/tx packets. Although spec implies that "if a packet larger than eight bytes is received from the remote computer, the device must break the larger packet into eight-byte packets before sending the data to the Debug Port", the real PLX NET20DC device does not handle it right - data is corrupted on debug port end if serial interface sends >8 byte urbs.

2008-07-21USB: fix usb_reset_device and usb_reset_composite_device(take 3)Ming Lei
This patch renames the existing usb_reset_device in hub.c to usb_reset_and_verify_device and renames the existing usb_reset_composite_device to usb_reset_device. Also the new usb_reset_and_verify_device does't need to be EXPORTED . The idea of the patch is that external interface driver should warn the other interfaces' driver of the same device before and after reseting the usb device. One interface driver shoud call _old_ usb_reset_composite_device instead of _old_ usb_reset_device since it can't assume the device contains only one interface. The _old_ usb_reset_composite_device is safe for single interface device also. we rename the two functions to make the change easily. This patch is under guideline from Alan Stern.
