| 58e7847 | Jeff Mahoney | 27 June 2007, 21:09:58 UTC | saa7134: fix thread shutdown handling This patch changes the test for the thread pid from >= 0 to > 0. When the saa8134 driver initialization fails after a certain point, it goes through the complete shutdown process for the driver. Part of shutting it down includes tearing down the thread for tv audio. The test for tearing down the thread tests for >= 0. Since the dev structure is kzalloc'd, the test will always be true if we haven't tried to start the thread yet. We end up waiting on pid 0 to complete, which will never happen, so we lock up. This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

| 59faba1 | Trent Piepho | 27 June 2007, 21:09:54 UTC | Fix Kconfig dependency problems wrt boolean menuconfigs If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool promotes the tristate from m to y. This ends up causing a problem with several menuconfigs that look like: menuconfig BAR bool depends on BAZ [tristate] if BAR config FOO tristate endif The solution used here is to add the dependencies of BAR to the if statement, so that items in the if block will gain a direct non-bool-promoted dependency on BAZ. This is how it would work if a menu was used instead of an if block. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Mauro Carvalho Chehab <mchehab@infradead.org> Cc: "David S.

Now Petr Vandrovec reports that its BUG_ON(mapcount > 100000) can easily crash a CONFIG_DEBUG_VM=y system. That limit was just an arbitrary number to protect against an infinite loop. We could raise it to something enormous (depending on sizeof struct vma and size of memory?); but I rather think validate_anon_vma has outlived its usefulness, and is better just removed - which gives a magnificent performance boost to anything like Petr's test program ;) Of course, a very long anon_vma list is bad news for preemption latency, and I believe there has been one recent report of such: let's not forget that, but validate_anon_vma only makes it worse not better.

| 172d049 | Bjorn Helgaas | 27 June 2007, 21:09:52 UTC | PNP SMCf010 quirk: auto-config device if BIOS left it broken Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or reports the wrong resources in _CRS. As a workaround, when we find such a device, try to auto-configure the device. This ignores the _CRS data, picks a config from _PRS, and runs _SRS to configure the device. This makes smsc-ircc2 work correctly with PNP resources (with no preconfiguration!) on all the machines I tested. I think Windows does something like this by default for all devices, so we should consider doing the same thing in Linux. This patch addresses part of the 2.6.22 regression: "no irda0 interface (2.6.21 was OK), smsc does not find chip" It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000, nw8240, and possibly other machines.

| 240e2df | Michael Halcrow | 27 June 2007, 21:09:44 UTC | eCryptfs: fix write zeros behavior This patch fixes the processes involved in wiping regions of the data during truncate and write events, fixing a kernel hang in 2.6.22-rc4 while assuring that zero values are written out to the appropriate locations during events in which the i_size will change. The range passed to ecryptfs_truncate() from ecryptfs_prepare_write() includes the page that is the object of ecryptfs_prepare_write(). This leads to a kernel hang as read_cache_page() is executed on the same page in the ecryptfs_truncate() execution path. This patch remedies this by limiting the range passed to ecryptfs_truncate() so as to exclude the page that is the object of ecryptfs_prepare_write(); it also adds code to ecryptfs_prepare_write() to zero out the region of its own page when writing past the i_size position. This patch also modifies ecryptfs_truncate() so that when a file is truncated to a smaller size, eCryptfs will zero out the contents of the new last page from the new size through to the end of the last page.

This will result in some races(especially the device generating the interrupt can see some inconsistent state, resulting in issues like stuck irq,..). Appended patch fixes the issue by taking proper lock and encapsulating irq_chip set_affinity() with a mask() before and an unmask() after. This fixes a MSI irq stuck issue reported by Darrick Wong. There are several more general bugs in this area(irq migration in the process context). For example, 1. Possibility of missing edge triggered irq. 2. Reliable method of migrating level triggered irq in the process context. We plan to look and close these in the near future. Eric says: In addition even with the fix from Suresh there is still at least one nasty hardware race in fixup_irqs(). However we exercise that code path rarely enough that we are unlikely to hit it in the real world, and that race seems to have existed since the code was merged. And a fix for that is not coming soon as it is an open investigation area if we can fix irq migration to work outside of irq context or if we have to rework the requirements imposed by the generic cpu hotplug and layer on fixup_irqs(). So this may come up again. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Eric W.

| ae62fbb | Paul Mackerras | 26 June 2007, 04:49:11 UTC | [POWERPC] Fix subtle FP state corruption bug in signal return on SMP This fixes a bug which can cause corruption of the floating-point state on return from a signal handler. If we have a signal handler that has used the floating-point registers, and it happens to context-switch to another task while copying the interrupted floating-point state from the user stack into the thread struct (e.g. because of a page fault, or because it gets preempted), the context switch code will think that the FP registers contain valid FP state that needs to be copied into the thread_struct, and will thus overwrite the values that the signal return code has put into the thread_struct. This can occur because we clear the MSR bits that indicate the presence of valid FP state after copying the state into the thread_struct. To fix this we just move the clearing of the MSR bits to before the copy. A similar potential problem also occurs with the Altivec state, and this fixes that in the same way.

For absolute code, %ebx serves as a local register and has no specified role in the function calling sequence. In either case, a function must preserve the register value for the caller. acpi_copy_wakeup_routine overrides %ebx without saving it, this may corrupt the called data. Kevin found that most time the value of Sx is saved in %esi, however sometimes compiler also uses %ebx.

| 4f84e4b | Joshua Wise | 24 June 2007, 00:16:45 UTC | x86_64: fix misplaced `continue' in mce.c Background: When a userspace application wants to know about machine check events, it opens /dev/mcelog and does a read(). Usually, we found that this interface works well, but in some cases, when the system was taking large numbers of machine check exceptions, the read() would hang. The system would output a soft-lockup warning, and the daemon reading from /dev/mcelog would suck up as much of a single CPU as it could spinning in system space. Description: This patch fixes this bug. In particular, there was a "continue" inside a timeout loop that presumably was intended to break out of the outer loop, but instead caused the inner loop to continue. This patch also makes the condition for the break-out a little more evident by changing a !time_before to a time_after_eq. Result: The read() no longer hangs in this test case. Testing: On my system, I could replicate the bug with the following command: # for i in `seq 15000`; do ./inject_sbe.sh; done where inject_sbe.sh contains commands to inject a single-bit error into the next memory write transaction.

| 1ed8a2b | Egmont Koblinger | 24 June 2007, 00:16:27 UTC | console UTF-8 fixes (fix) Recently my console UTF-8 patch went mainline. Here is an additional patch that fixes two nasty issues and improves a third one, namely: 1. My patch changed the behavior if a glyph is not found in the Unicode mapping table. Previously for Unicode values less than 256 or 512 the kernel tried to display the glyph from that position of the glyph table, which could lead to a different accented letter being displayed. I removed this fallback possibility and changed it to display the replacement symbol. As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package) lack Unicode mapping information, hence all you get is lots of question marks. Though theoretically it's actually a user-space bug (the font should be fixed), Behdad and I both believe that it'd be good to work around in the kernel by re-introducing the fallback solution for ASCII characters only. This sounds a quite reasonable decision, since all fonts ship the ASCII characters in the first 128 positions. This way users won't be surprised by lots of question marks just because s/he issued a not-so-perfectly parameterized setfont command. As this fallback is only re-introduced for code points below 128, you still won't see an accented letter replaced by another, but at least you'll always get the English letters right. 2. My patch introduced "question mark with inverted color attributes" as a last resort fallback glyph. Though it perfectly works on VGA console, on framebuffer you may end up with question marks that are highlighed but shouldn't be, and normal characters that are accidentally highlighed. This is caused by missing FLUSHes when changing the color attribute. 3. I've updated the table of double-width character based on Markus's updated version. Only ten new code poings (one interval) is added.
