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:

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 b2e3e658 It therefore applies to 2.6.25, 2.6.26 and linux-next. I merely merged the patches from Roland, Wenji and Takashi here. Credits to Roland McGrath <roland@redhat.com> Wenji Huang <wenji.huang@oracle.com> and Takashi Nishiie <t-nishiie@np.css.fujitsu.com> for providing the individual fixes. - Changelog : - Integrated Takashi's Makefile modification to clear Module.markers upon make clean.

Two small updates to the pcf857x driver: (a) the max732[89] chips are also second sources for the pcf8574/a, and (b) add a mutex to prevent trashing the cached state. Adding the lock is effectively a bugfix, although it seems unlikely that anyone would have run into the issue it protects against. Signed-off-by:

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:

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. Signed-off-by:

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. Signed-off-by:

A couple of USB register initializations had to be changed on MPC85xx platforms. This is due to the internal SoC buses being different on MPC83xx SoCs vs MPC85xx SoCs. We currently handle this via an ifdef since 83xx and 85xx are mutually exclusive kernel builds. Signed-off-by:

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. Instead of passing the minor number to the callback, which must then reconstruct the entire dev_t value, the patch passes the dev_t value directly. Signed-off-by:

This patch (as1107) fixes a small bug in the usbfs registration and unregistration code. It avoids leaving an error value stored in the device's usb_classdev field and it avoids trying to unregister a NULL pointer. (It also fixes a rather extreme overuse of whitespace.) Signed-off-by:

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. Signed-off-by:
