* tpm: fix sleep-in-spinlockParag Warudkar2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | flush_scheduled_work() can sleep, and we're calling it under spinlock. AFAICS, moving flush_scheduled_work before spin_lock() should not cause any problems. Reason being - The only thing that can race against tpm_release is tpm_open (tpm_release is called when last reference to the file is closed and only thing that can happen after that is tpm_open??) and tpm_open acquires driver_lock and more over it bails out with EBUSY if chip->num_opens is greater than 0. I also moved chip->num_pending-- to after deleting timer and setting data pending as it looks more correct for the paranoid although it probably doesn't matter as it is guarded by driver_lock. None the less this change should not cause problems. While I was at it I noticed a missing NULL check in tpm_register_hardware which is fixed with this patch as well.

* console UTF-8 fixesEgmont Koblinger2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UTF-8 part of the vt driver suffers from the following issues which are addressed in my patch: 1) If there's no glyph found for a particular valid UTF-8 character, we try to display U+FFFD. However if this one is not found either, here's what the current kernel does: - First, if the Unicode value is less than the number of glyphs, use the glyph directly from that position of the glyph table. While it may be a good idea in the 8-bit world, it has absolutely no sense with Unicode in mind. For example, if a Latin-2 font is loaded and an application prints U+00FB ("u with circumflex", not present in Latin-2) then as a fallback solution the glyph from the 0xFB position of the Latin-2 fontset (which is an "u with double accent" - a different character) is displayed. - Second, if this fallback fails too, a simple ASCII question mark is printed, which is visually undistinguishable from a real question mark. I changed the code to skip the first step (except if in non-UTF-8 mode), and changed the second step to print the question mark with inverse color attributes, so it is visually clear that it's not a real question mark, and resembles more to the common glyph of U+FFFD. 2) The UTF-8 decoder is buggy in many ways: - Lone continuation bytes (section 3.1 of Markus Kuhn's UTF-8 stress test) are not caught, they are displayed as some "random" (taken directly form the font table, see above) glyphs instead the replacement character. - Incomplete sequences (sections 3.2 and 3.3 of the stress test) emit no replacement character, but rather cause the subsequent valid character to be displayed more times(!). - The decoder is not safe: overlong sequences are not caught currently, they are displayed as if these were valid representations. This may even have security impacts. - The decoder does not handle D800..DFFF and FFFE..FFFF specially, it just emits these code points and lets it be looked up in the glyph table. Since these are invalid code points, I replace them by U+FFFD and hence give no chance for them to be looked up in the glyph table. (Assuming no font ships glyphs for these code points, this change is not visible to the users since the glyph shown will be the same.) With my fixes to the decoder it now behaves exactly as Markus Kuhn's stress test recommends. 3) It has no concept of double-width (CJK) characters. It's way beyond the scope of my patch to try to display them, but at least I think it's important for the cursor to jump two positions when printing such characters, since this is what applications (such as text editors) expect. Currently the cursor only jumps one position, and hence applications suffer from displaying and refreshing problems, and editing some English letters that are preceded by some CJK characters in the same line is a nightmare. With my patch an additional space is inserted after the CJK character has been printed (which usually means a replacement symbol of course). (If U+FFFD isn't availble and hence an inverse question mark is displayed in the first cell, I keep the inverted state for the space in the 2nd column so it's quite easy to see that they are tied together.) 4) There is a small built-in table of zero-width spaces that are not to be printed but silently skipped. U+200A is included there, but it's not a zero-width character, so I remove it from there.

| | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

* tty: introduce no_tty and use it in selinuxEric W. Biederman2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | While researching the tty layer pid leaks I found a weird case in selinux when we drop a controlling tty because of inadequate permissions we don't do the normal hangup processing. Which is a problem if it happens the session leader has exec'd something that can no longer access the tty. We already have code in the kernel to handle this case in the form of the TIOCNOTTY ioctl. So this patch factors out a helper function that is the essence of that ioctl and calls it from the selinux code. This removes the inconsistency in handling dropping of a controlling tty and who knows it might even make some part of user space happy because it received a SIGHUP it was expecting. In addition since this removes the last user of proc_set_tty outside of tty_io.c proc_set_tty is made static and removed from tty.h Signed-off-by: Eric W.

* Fixes and cleanups for earlyprintk aka boot consoleGerd Hoffmann2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The console subsystem already has an idea of a boot console, using the CON_BOOT flag. The implementation has some flaws though. The major problem is that presence of a boot console makes register_console() ignore any other console devices (unless explicitly specified on the kernel command line). This patch fixes the console selection code to *not* consider a boot console a full-featured one, so the first non-boot console registering will become the default console instead. This way the unregister call for the boot console in the register_console() function actually triggers and the handover from the boot console to the real console device works smoothly. Added a printk for the handover, so you know which console device the output goes to when the boot console stops printing messages. The disable_early_printk() call is obsolete with that patch, explicitly disabling the early console isn't needed any more as it works automagically with that patch. I've walked through the tree, dropped all disable_early_printk() instances found below arch/ and tagged the consoles with CON_BOOT if needed. The code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf). Changes to last version: Rediffed against -rc3, adapted to mips cleanups by Ralf, fixed "udbg-immortal" cmd line arg on powerpc.

* Use stop_machine_run in the Intel RNG driverPrarit Bhargava2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | Replace call_smp_function with stop_machine_run in the Intel RNG driver. CPU A has done read_lock(&lock) CPU B has done write_lock_irq(&lock) and is waiting for A to release the lock. A third CPU calls call_smp_function and issues the IPI. CPU A takes CPU C's IPI. CPU B is waiting with interrupts disabled and does not see the IPI. CPU C is stuck waiting for CPU B to respond to the IPI. Deadlock. The solution is to use stop_machine_run instead of call_smp_function (call_smp_function should not be called in situations where the CPUs may be suspended).

Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.

* ipmi: allow shared interruptsCorey Minyard2007-05-08
| | | | | | | | | | | | | | | | The IPMI driver used enable_irq and disable_irq when it got into situations where it couldn't allocate memory; it did this to avoid having the interrupt just lock the machine when it couldn't get memory to perform the transaction to disable the interrupt. This patch modifies the driver to not use disable_irq and enable_irq. It instead sends the messages to the BMC to perform this operation. It also makes sure interrupts are cleanly disabled when the interface is shut down and cleans up some shutdown things that are no longer necessary.

* ipmi: add powerpc openfirmware sensingCorey Minyard2007-05-08
| | | | | | | | | | | | | | | Add support for of_platform_driver to the ipmi_si module. When loading the module, the driver will be registered to of_platform. The driver will be probed for all devices with the type ipmi. It's supporting devices with compatible settings ipmi-kcs, ipmi-smic and ipmi-bt. Only ipmi-kcs could be tested.

| | | | | | | | | | | | | | | | | | | | | | | | Bugzilla Bug #9457 Add refcounting of user waiters to the DRM hardware lock, so that we can use DRM_LOCK_CONT flag more conservatively. Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager Signed-off-by: Dave Airlie <airlied@linux.ie>

| | | | | | | | | | | | | | | | | | The overflows could lead to the AGP aperture overlapping the framebuffer are in the card's address space when the latter is located at the very end of th 32 bit address space, which would result in a freeze on X server startup, probably because the card read commands from the framebuffer instead of from AGP.
