2007-07-06x86_64: fix headers_installDavid Woodhouse
A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of files all of which are using the same #ifdef guard, "__ASM_STUB_" with no postfix. So the second and later asm files #included in the same C file (often through standard headers like ioctl.h) yields no symbols. Strangeness with the Ubuntu 'tell me if I support something that's not explcitly mentioned in POSIX, and I'll strip it out' shell, I believe.

2007-07-06MTRR: Fix race causing set_mtrr to go into infinite loopLoic Prylli
Processors synchronization in set_mtrr requires the .gate field to be set after .count field is properly initialized. Without an explicit barrier, the compiler was reordering those memory stores. That was sometimes causing a processor (in ipi_handler) to see the .gate change and decrement .count before the latter is set by set_mtrr() (which then hangs in a infinite loop with irqs disabled).

2007-07-06i386: fix regression, endless loop in ptrace singlestep over an int80Jason Wessel
The commit 635cf99a80f4ebee59d70eb64bb85ce829e4591f introduced a regression. Executing a ptrace single step after certain int80 accesses will infinitely loop and never advance the PC. The TIF_SINGLESTEP check should be done on the return from the syscall and not before it. I loops on each single step on the pop right after the int80 which writes out to the console. At that point you can issue as many single steps as you want and it will not advance any further. The test case is below: /* Test whether singlestep through an int80 syscall works. */ #define _GNU_SOURCE #include <stdio.h> #include <unistd.h> #include <fcntl.h> #include <sys/ptrace.h> #include <sys/wait.h> #include <sys/mman.h> #include <asm/user.h> #include <string.h> static int child, status; static struct user_regs_struct regs; static void do_child() { char str[80] = "child: int80 test\n"; ptrace(PTRACE_TRACEME, 0, 0, 0); kill(getpid(), SIGUSR1); write(fileno(stdout),str,strlen(str)); asm ("int $0x80" : : "a" (20)); /* getpid */ } static void do_parent() { unsigned long eip, expected = 0; again: waitpid(child, &status, 0); if (WIFEXITED(status) || WIFSIGNALED(status)) return; if (WIFSTOPPED(status)) { ptrace(PTRACE_GETREGS, child, 0, &regs); eip = regs.eip; if (expected) fprintf(stderr, "child stop @ %08lx, expected %08lx %s\n", eip, expected, eip == expected ?

2007-07-06Fix elf_core_dump() when writing arch specific notes (spu coredumps)Michael Ellerman
elf_core_dump() supports dumping arch specific ELF notes, via the #define ELF_CORE_WRITE_EXTRA_NOTES. Currently the only user of this is the powerpc spu coredump code. There is a bug in the handling of foffset WRT the arch notes, which causes us to erroneously increment foffset by the size of the arch notes, leaving a block of zeroes in the file, and causing all subsequent data in the file to be at <supposed position> + <arch note size>. eg: LOAD 0x050000 0x00100000 0x00000000 0x20000 0x20000 R E 0x10000 Tells us we should have a chunk of data at 0x50000. The truth is the data is at 0x90dbc = 0x50000 + 0x40dbc (the size of the arch notes). This bug prevents gdb from reading the core file correctly. The simplest fix is to simply remember the size of the arch notes, and add it to foffset after we've written the arch notes. The only drawback is that if the arch code doesn't write as many bytes as it said it would, we end up with a broken core dump again. For now I think that's a reasonable requirement. Tested on a Cell blade, gdb no longer complains about the core file being bogus. While I'm here I should point out that the spu coredump code does not work if we're dumping to a pipe - we'll have to wait for 23 to fix that.

2007-07-05Fix slab redzone alignmentDavid Woodhouse
Commit b46b8f19c9cd435ecac4d9d12b39d78c137ecd66 fixed a couple of bugs by switching the redzone to 64 bits. Unfortunately, it neglected to ensure that the _second_ redzone, after the slab object, is aligned correctly. This caused illegal instruction faults on sparc32, which for some reason not entirely clear to me are not trapped and fixed up. Two things need to be done to fix this: - increase the object size, rounding up to alignof(long long) so that the second redzone can be aligned correctly. - If SLAB_STORE_USER is set but alignof(long long)==8, allow a full 64 bits of space for the user word at the end of the buffer, even though we may not _use_ the whole 64 bits. This patch should be a no-op on any 64-bit architecture or any 32-bit architecture where alignof(long long) == 4. Of the others, it's tested on ppc32 by myself and a very similar patch was tested on sparc32 by Mark Fortescue, who reported the new problem. Also, fix the conditions for FORCED_DEBUG, which hadn't been adjusted to the new sizes. Again noticed by Mark.

2007-07-04Remove the blink driverLinus Torvalds
Yeah, we could have just disabled it, but there's work on a new one that isn't as fundamentally broken, so there really doesn't seem to be any point in keeping it around. The recent timer cleanup broke the only valid use, and when I say "valid", I obviously mean "totally broken". So it's not like it works, or really even can work in the current format that uses the unsafe "panic" LED blinking routines.. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-04[ARM] Fix non-page aligned boot time mappingsRussell King
AT91SAM9260 stopped booting with the recent changes to MM initialisation - it was asking for a non-aligned virtual address which caused loops to be non-terminal. Fix this by rounding virtual addresses down, but remember to include the offset in the length, and round the length up to the following page. This means that asking for a mapping of 4K starting at 2K into a page maps two pages as one would expect. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-03dio: remove bogus refcounting BUG_ONZach Brown
Badari Pulavarty reported a case of this BUG_ON is triggering during testing. It's completely bogus and should be removed. It's trying to notice if we left references to the dio hanging around in the sync case. They should have been dropped as IO completed while this path was in dio_await_completion(). This condition will also be checked, via some twisty logic, by the BUG_ON(ret != -EIOCBQUEUED) a few lines lower. So to start this BUG_ON() is redundant. More fatally, it's dereferencing dio-> after having dropped its reference. It's only safe to dereference the dio after releasing the lock if the final reference was just dropped. Another CPU might free the dio in bio completion and reuse the memory after this path drops the dio lock but before the BUG_ON() is evaluated. This patch passed aio+dio regression unit tests and aio-stress on ext3.

2007-07-03Revert HPET resource reservationAndi Kleen
Matthias Lenk reports that the PCI subsystem would move the HPET on SB400/SB600-based systems, where the HPET is in BAR1 of the SMbus controller. The reason? The ACPI layer registered the PCI MMIO range as being busy too early, before PCI enumeration had happened, causing the PCI layer to decide that it should relocate the resources somewhere else. Firmware resources should be marked busy _after_ the PCI enumeration and probing has happened, not before. Remove the too-early reservation, we'll fix it up to do it properly later. In the meantime, this solves the regression.

2007-07-03NTP: remove clock_was_set() call to prevent deadlockThomas Gleixner
The clock_was_set() call in seconds_overflow() which happens only when leap seconds are inserted / deleted is wrong in two aspects: 1. it results in a call to on_each_cpu() with interrupts disabled 2. it is potential deadlock source vs. call_lock in smp_call_function() The only possible side effect of the removal might be, that an absolute CLOCK_REALTIME timer fires 1 second too late, in the rare case of leap second deletion and an absolute CLOCK_REALTIME timer which expires in the affected time frame. It will never fire too early. This was probably observed by the reporter of a June 30th -> July 1st hang: http://lkml.org/lkml/2007/7/3/103 A similar problem was observed by Dave Jones, who provided a screen shot with a lockdep back trace, which allowed to analyse the problem.

Spotted and tested by Thomas Sattler <tsattler@gmx.de>. cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while holding cinergyt2->sem. This leads to deadlock because work->func() needs the same mutex to complete. Another bug is that this code in fact can't reliably stop the re-arming delayed_work. Convert this code to use cancel_rearming_delayed_work() and move it out of ->sem. Another mutex, ->wq_sem, was added to protect against the concurrent open/resume.

2007-07-03V4L/DVB (5808): Bttv: fix v4l1 breaking the driverTrent Piepho
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as the first user after the driver is loaded, the driver wedges itself and will never capture properly. Even if one uses a V4L2 application later, it still won't work. If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2 driver, then the driver will be ok. One can then run a V4L1 application, and it will work. It turns out the problem is with norm changing and the crop support that was added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was set too across opens. If one changes the norm via V4L1, the cropping parameters are not reset like they should be, and they'll remain broken across device opens. This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl VIDIOCSCHAN handler. The norm is set via the existing call to set_input(), which calls set_tvnorm(), which will reset the cropping values now that it is able to detect the norm change.
