2008-07-22usb_serial: API all changeAlan Cox42-1720/+1820
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 Desnoyers3-2/+5
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 Reiser2-1/+4
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>

2008-07-21HP iLO driverDavid Altobelli4-0/+971
A driver for the HP iLO/iLO2 management processor, which allows userspace programs to query the management processor. Programs can open a channel to the device (/dev/hpilo/dXccbN), and use this to send/receive queries. The O_EXCL open flag is used to indicate that a particular channel cannot be shared between processes. This driver will replace various packages HP has shipped, including hprsm and hp-ilo.

2008-07-21sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen24-112/+239
This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections.

2008-07-21sysfs-rules.txt: reword API stability statementNathan Lynch1-3/+2
The first paragraph of this document implies that user space developers shouldn't use sysfs at all, but then it goes on to describe rules that developers should follow when accessing sysfs. Not only is this somewhat self-contradictory, it has been shown to discourage developers from using established sysfs interfaces. A note of caution is more appropriate than a blanket "sysfs will never be stable" assertion.

debugfs_remove_recursive() will remove a dentry and all its children. Drivers can use this to zap their whole debugfs tree so that they don't need to keep track of every single debugfs dentry they created.

2008-07-21always enable FW_LOADER unless EMBEDDED=yAdrian Bunk1-1/+2
James Bottomley recently discovered that we have {request,release}_firmware() dummies for the case of the actual functions not being available and has a fix for the bug that was actually causing build errors for built-in users with CONFIG_FW_LOADER=m. But now missing selects on FW_LOADER are no longer visible at compile-time at all and can become runtime problems. FW_LOADER is infrastructure with relatively small codesize we can safely enable for everyone, and only for people who really need small kernels (and can be expected to know what they are doing) it matters being able to disable it. This patch therefore always sets FW_LOADER=y and allows users only to disable it with EMBEDDED=y. As a bonus, we can then get rid of all "select FW_LOADER" plus the due to it required "depends on HOTPLUG" which removes some complexity from our Kconfig files.

2008-07-21sysdev: fix debugging statements in registration code.Ben Dooks1-3/+8
The systdev_class_register() and sysdev_register() functions have pr_debug() statements which are enabled when the user selects the driver core debug. Both of these routines do not produce the correct output, as they make assumptions about data which has not been initialised. In sysdev_class_register() the code uses the kobject_name(&cls->kset.kobj) at the start of the function, but this is not setup until later in the same call. Change this to use cls->name which is passed in from the caller. The sysdev_register() function tries to get the name of the sysdev by kobject_name(&sysdev->kobj), but that isn't setup until later in the same function so change this message to use the name of the sysdev's class and add another message once the name is initialised.
