2009-02-17Fix Intel IOMMU write-buffer flushingDavid Woodhouse1-1/+13
This is the cause of the DMA faults and disk corruption that people have been seeing. Some chipsets neglect to report the RWBF "capability" -- the flag which says that we need to flush the chipset write-buffer when changing the DMA page tables, to ensure that the change is visible to the IOMMU. Override that bit on the affected chipsets, and everything is happy again. Thanks to Chris and Bhavesh and others for helping to debug.

2009-02-17Fix incomplete __mntput lockingAl Viro1-2/+4
Getting this wrong caused WARNING: at fs/namespace.c:636 mntput_no_expire+0xac/0xf2() due to optimistically checking cpu_writer->mnt outside the spinlock. Here's what we really want: * we know that nobody will set cpu_writer->mnt to mnt from now on * all changes to that sucker are done under cpu_writer->lock * we want the laziest equivalent of spin_lock(&cpu_writer->lock); if (likely(cpu_writer->mnt != mnt)) { spin_unlock(&cpu_writer->lock); continue; } /* do stuff */ that would make sure we won't miss earlier setting of ->mnt done by another CPU. Anyway, for now we just move the spin_lock() earlier and move the test into the properly locked region.

The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug causing decoder commands to crash. The decoder commands should have been handled from the video_ioctl2 default handler, ensuring correct mapping of the argument between user and kernel space. Unfortunately they ended up before the video_ioctl2 call, causing random crashes. Thanks to hannes@linus.priv.at for testing and helping me track down the cause!

On Mon, 02 Feb 2009, Hartmut wrote: This change set is wrong. The affected functions cannot be called from an interrupt context, because they may process large buffers. In this case, interrupts are disabled for a long time. Functions, like dvb_dmx_swfilter_packets(), could be called only from a tasklet. This change set does hide some strong design bugs in dm1105.c and au0828-dvb.c. Please revert this change set and do fix the bugs in dm1105.c and au0828-dvb.c (and other files).

The demuxer is far too much work to be done with IRQs off. IMHO, even doing it under a spin-lock is excessive. It should be a mutex. Drivers should use a work-queue to feed the demuxer.

2009-02-17V4L/DVB (10527): tuner: fix TUV1236D analog/digital setupMauro Carvalho Chehab1-6/+4
As reported by David Engel <david@istwok.net>, ATSC115 doesn't work fine with mythtv. This software opens both analog and dvb interfaces of saa7134. What happens is that some tuner commands are going to the wrong place, as shown at the logs: Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01 This happens due to a hack at TUV1236D analog setup, where it replaces tuner address, at 0x61 for 0x0a, in order to save a few memory bytes. The code assumes that nobody else would try to access the tuner during that setup, but the point is that there's no lock to protect such access. So, this opens the possibility of race conditions to happen. Instead of hacking tuner address, this patch uses a temporary var with the proper tuner value to be used during the setup. This should save the issue, although we should consider to write some analog/digital lock at saa7134 driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

For quite some time users with various UPSes from Powercom were forced to play magic with bind/unbind in /sys in order to be able to see the UPSes. The beasts does not work as HID devices, even if claims to do so. cypress_m8 driver works with the devices instead, creating a normal serial port with which normal UPS controlling software works. The manufacturer confirmed the upcoming models with proper HID support will have different device IDs. In any way, it's wrong to have two completely different modules for one device in kernel.

Commit 871af1210f13966ab911ed2166e4ab2ce775b99d (libata: Add 32bit PIO support) has caused all kinds of errors on the ATAPI devices, so it has been empirically proven that one shouldn't try to read/write an extra data word when a device is not expecting it already. "Don't do it then"; however, still use a chance to do 32-bit read/write one last time when there are exactly 3 trailing bytes. Oh, and stop pointlessly swapping the bytes to and fro on big-endian machines by using io*_rep() accessors which shouldn't byte-swap. This patch should fix the kernel.org bug #12609.

2009-02-15scripts: add x86 register parser to markup_oops.plArjan van de Ven1-6/+100
An oops dump also contains the register values. This patch parses these for (32 bit) x86, and then annotates the disassembly with these values; this helps in analysis of the oops by the developer, for example, NULL pointer or other pointer bugs show up clearly this way.

2009-02-15kbuild: add sys_* entries for syscalls in tagsRabin Vincent1-2/+5
Currently, it is no longer possible to use the tags file to jump to system call function definitions with sys_foo, because the definitions are obscured by use of the SYSCALL_DEFINE* macros. This patch adds the appropriate option to ctags to make it see through the macro. Also, it adds the ENTRY() work already done for Exuberant to Emacs too.
