2.6.9-final changelogSummary of changes from v2.6.9-rc4 to v2.6.9-final ============================================ <nickpiggin@yahoo.com.au> [PATCH] ACPI: check parameter for NULL ACPI still explodes on my old PII and stops it booting. Anyway, it is oopsing in drivers/acpi/scan.c line 207 where element (which is NULL) gets dereferenced. The ACPI bios on this thing has always seemed to be pretty broken, but this at least allows the 'power' button to continue to work (the only reason why I want ACPI). <sreenib@lsil.com> [PATCH] megaraid 2.20.4: fix a data corruption bug Fixes a data corruption issue. Because of a typo in the driver, IO packets were wrongly shared by the IOCTL path. This caused the whole IO command to be replaced by an incoming IOCTL command. <dwmw2@infradead.org> [PATCH] ppc64: one more explicit cmp instruction sizing Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <alborchers@steinerpoint.com> [PATCH] USB: corrected digi_acceleport 2.6.9-rc1 fix for hang on disconnect - Fixed hang on disconnect in digi_acceleport USB serial driver. See http://bugme.osdl.org/show_bug.cgi?id=2459. Close after disconnect no longer tries to communicate with the device.

No video data can be retrieved from the webcam. The following patch seems enough to solve the problem. (just inverting the order at which the old and new data blocks are sent to the user).

Many thanks to Olaf Hering for isolating the failure mode, and testing this fix! Once once CPU starts scanning, any other might as well finish right away. This fix just adds a flag to detect that case.

The usblp driver was calling usb_buffer_free() from usblp_cleanup(), which runs after disconnect() if a user process holds the device open. But once the usb_device is gone usb_buffer_free() will oops. The patch frees the buffers in usb_disconnect() instead. Recently Joost Witteveen reported the same oops and found that the patch solved it for him. So there shouldn't be problems with accepting it.

It's caused by hid calling hiddev_exit before unregistering itself which in turn calls hiddev_disconnect. hiddev_exit removes the directory which contains the hiddev devices. Therefore it needs to be called after the hiddev devices have been disconnected.

SGI Modid: xfs-linux:xfs-kern:19632a Signed-off-by: Nathan Scott <nathans@sgi.com> <nathans@sgi.com> [XFS] Fix regression when running in laptop mode, causes hangs on sync. SGI Modid: xfs-linux:xfs-kern:19744a Signed-off-by: Nathan Scott <nathans@sgi.com> <hch@sgi.com> [XFS] fix a freeze/thaw deadlock Signed-off-by: Nathan Scott <nathans@sgi.com> <clameter@sgi.com> [PATCH] time interpolator fixes - Remove the setting of CLOCK_REALTIME and CLOCK_MONOTONIC resolution according to the interpolator resolution since this causes periodic timer signals to fail. The clocks will still be high-resolution but the "resolution" reported reflects the timer intervals possible via timer_settime (also more conformant to what the Single Unix Specification says). - Make the IA64 clock_gettime fastcall fall back on negative clock numbers instead of returning CLOCK_REALTIME.

Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <akpm@osdl.org> [PATCH] revert writeback threshold changes The post-2.6.8 recent tweaks to the page writeback thresholding code seems to be doing the wrong thing for small unmapped_ratios - nathans had a few problems with it. The problem it was trying to fix is minor and fairly theoretical anyway, so back it out to the old code.

The latest kernel cannot be linked for m32r, because the following experimental syscalls doesn't exist in the prepatch kernel of bk-tree. * include/asm-m32r/unistd.h: - Remove syscalls from #285(perfctr_info) to #293(keyctl). * arch/m32r/kernel/entry.S: ditto.

The new kernel and old library pair does not work. So, those who want to use the new kernel must use a new version of glibc (the GNU C library), which uses the "mmap2(_NR_mmap2)" syscall for __mmap() instead of the "old_mmap(__NR_mmap)". The new glibc package, libc6_2.3.2.ds1-16.0.3_m32r.deb, is provided on the following site, please apt-get/download it and upgrade. http://debian.linux-m32r.org/dists/03_cambrian/main/binar...

This leaves one reference in cyber2000fb that 'make buildcheck' complains about, but I believe that it's OK, that being ".probe" here: static struct pci_driver cyberpro_driver = { .name = "CyberPro", .probe = cyberpro_pci_probe, Signed-off-by: Randy Dunlap <rddunlap@osdl.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <andrea@novell.com> [PATCH] ptep_establish smp race x86 PAE >4G This avoid userspace mm corruption during COWs with threads (i.e. malloc;fork;clone) on x86 PAE with >4G of ram Signed-Off-By: Andrea Arcangeli <andrea@novell.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <dtor_core@ameritech.net> [PATCH] Fix oops in parkbd parkbd - zero-fill allocated serio structure to prevent Oops when registering port.

The same fix already present in the MTD CVS.

(http://linus.bkbits.net:8080/linux-2.5/cset@3ef4851dGg0fx...) Process start times are reported to userspace in units of 1/USER_HZ since boot, thus applications as procps need the value of "uptime" to convert them into absolute time. Currently "uptime" is derived from an ntp-corrected time base, but process start time is derived from the free-running "jiffies" counter. This results in inaccurate, drifting process start times as seen by the user, even if the exported number stays constant, because the users notion of "jiffies" changes in time. It's John Stultz's patch anyways, which I only messed up a bit, but since people started trading signed-off lines on lkml: Signed-off-by: Tim Schmielau <tim@physik3.uni-rostock.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <sds@epoch.ncsc.mil> [PATCH] SELinux: retain ptracer SID across fork This fixes a bug in SELinux to retain the ptracer SID (if any) across fork. Otherwise, SELinux will always deny attempts by traced children to exec domain-changing programs even if the policy would have allowed the tracer to trace the new domains as well.

First, the stacked security module will get both mmap and mprotect callbacks for an mprotect call, which is wrong. Secondly, the vm_flags value contains VM_* bits, and these do not match the MAP_* bits of the same name or function, so it passes bogus flags and causes every mprotect to be treated as if MAP_SHARED were in use. The patch shares the common code while not having one function call the other, and fixes these two bugs.

So let's fix this. Also, the below code is useless, since if CONFIG_DEBUG_INFO is y, then CONFIG_FRAME_POINTER is always y. ifeq ($(CONFIG_DEBUG_INFO),y) CFLAGS := $(subst -fomit-frame-pointer,,$(CFLAGS)) endif Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade_spam@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <blaisorblade_spam@yahoo.it> [PATCH] uml: force using /bin/bash for building This forces make to use bash rather than whatever /bin/sh is linked to.

In detail: Rename ubd_finish() to __ubd_finish() and remove ubd_io_lock from it. Add wrapper, ubd_finish(), which grabs lock before calling __ubd_finish(). Update do_ubd_request to use the lock free __ubd_finish() to avoid deadlock. Also, apparently prepare_request is called with ubd_io_lock held, so remove locks there.

This is against Principle of Least Surprise, so remove this difference. Also the current ubd=sync behaviour is completely useless: it is to make sure that when the kernel has synched its I/O to the virtual disk, the host does not invalidate this with his caching; this causes ReiserFS corruption. But since actually we call end_request() only after the io_thread has done its work, we never lie to the block layer. Using O_SYNC as we do when replacing ubd#= with ubd#s= is enough.

I'll check if the original code can be included directly (i.e. "#include") after 2.6.9. Without this patch, every 2.6 UML release corrupts the checksum of every UDP fragmented packet with size >= MTU (verified by various people, we all agree on this issue; nobody reported "Works fine here"). The corrupted packets are not accepted, thus blocking any kind of communication with large-sized UDP packets. In fact, I've even dissected the UML -> host traffic before and after this patch with Ethereal - and it always reported an incorrect checksum for fragmented UDP packets before and always correct after applying the patch.

This is a no-op on any architecture where getting the page table spinlock will already do the ordering (notably x86), but other architectures can care. <torvalds@ppc970.osdl.org> Take the whole PCI bus range into account when scanning PCI bridges. A bridge that has been set up by firmware to cover multiple PCI buses but doesn't actually have anything connected behind some of them caused us to use the incorrect maxmimum bus number span when scanning the bridge chip. Problem reported by Tim Saunders, with Russell King suggesting the fix. <johnrose@austin.ibm.com> [PATCH] PCI Hotplug: rpaphp safe list traversal Hoping you will accept this fix.
