2008-07-22usb_serial: API all changeAlan Cox
USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-07-22markers: fix duplicate modpost entryMathieu Desnoyers
When a kernel was rebuilt, the previous Module.markers was not cleared. It caused markers with different format strings to appear as duplicates when a markers was changed. This problem is present since scripts/mod/modpost.c started to generate Module.markers, commit b2e3e658b344c6bcfb8fb694100ab2f2b5b2edb0 It therefore applies to 2.6.25, 2.6.26 and linux-next.

2008-07-22execve filename: document and export via auxiliary vectorJohn Reiser
The Linux kernel puts the filename argument of execve() into the new address space. Many developers are surprised to learn this. Those who know and could use it, object "But it's not documented." Those who want to use it dislike the expression (char *)(1+ strlen(env[-1+ n_env]) + env[-1+ n_env]) because it requires locating the last original environment variable, and assumes that the filename follows the characters. This patch documents the insertion of the filename, and makes it easier to find by adding a new tag AT_EXECFN in the ElfXX_auxv_t; see <elf.h>. In many cases readlink("/proc/self/exe",) gives the same answer. But if all the original pages get unmapped, then the kernel erases the symlink for /proc/self/exe. This can happen when a program decompressor does a good job of cleaning up after uncompressing directly to memory, so that the address space of the target program looks the same as if compression had never happened. One example is http://upx.sourceforge.net . One notable use of the underlying concept (what path containED the executable) is glibc expanding $ORIGIN in DT_RUNPATH. In practice for the near term, it may be a good idea for user-mode code to use both /proc/self/exe and AT_EXECFN as fall-back methods for each other. /proc/self/exe can fail due to unmapping, AT_EXECFN can fail because it won't be present on non-new systems. The auxvec or {AT_EXECFN}.d_val also can get overwritten, although in nearly all cases this would be the result of a bug. The runtime cost is one NEW_AUX_ENT using two words of stack space. The underlying value is maintained already as bprm->exec; setup_arg_pages() in fs/exec.c slides it for stack_shift, etc. Signed-off-by: John Reiser <jreiser@BitWagon.com> Cc: Roland McGrath <roland@redhat.com> Cc: Jakub Jelinek <jakub@redhat.com> Cc: Ulrich Drepper <drepper@redhat.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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.

2008-07-21usbfs: fix race between open and unregisterAlan Stern
This patch (as1106) fixes a race between opening and unregistering device files in usbfs.

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.

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: 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.
