In most cases we check the size of the bitmap file before reading data from it. However when reading the superblock, we always read the first PAGE_SIZE bytes, which might not always be appropriate. So limit that read to the size of the file if appropriate. Also, we get the count of available bytes wrong in one place, so that too can read past the end of the file.

Now that we sometimes step the array events count backwards (when transitioning dirty->clean where nothing else interesting has happened - so that we don't need to write to spares all the time), it is possible for the event count to return to zero, which is potentially confusing and triggers and MD_BUG. We could possibly remove the MD_BUG, but is just as easy, and probably safer, to make sure we never return to zero.

NFS V3 (and V4) support exclusive create by passing a 'cookie' which can get stored with the file. If the file exists but has exactly the right cookie stored, then we assume this is a retransmit and the exclusive create was successful. The cookie is 64bits and is traditionally stored in the mtime and atime fields. This causes a problem with Solaris7 as negative mtime or atime confuse it. So we moved two bits into the mode word instead. But inherited ACLs sometimes overwrite the mode word on create, so this is a problem. So we give up and just store 62 of the 64 bits and assume that is close enough.

NFSd assumes that largest number of pages that will be needed for a request+response is 2+N where N pages is the size of the largest permitted read/write request. The '2' are 1 for the non-data part of the request, and 1 for the non-data part of the reply. However, when a read request is not page-aligned, and we choose to use ->sendfile to send it directly from the page cache, we may need N+1 pages to hold the whole reply. This can overflow and array and cause an Oops. This patch increases size of the array for holding pages by one and makes sure that entry is NULL when it is not in use.

Recently cpufreq support on my laptop (Lenovo T60) broke completely: when it's plugged into AC it would never go higher than 1 GHz - neither 1.3 GHz nor 1.83 GHz is possible - no matter which governor (userspace, speed or ondemand) is used. After some cpufreq debugging i tracked the regression back to the following (totally correct) bug-fix commit: commit 0916bd3e Author: Dave Jones <davej@redhat.com> Date: Wed Nov 22 20:42:01 2006 -0500 [PATCH] Correct bound checking from the value returned from _PPC method. This bugfix, which makes other laptops work, made a previously hidden (BIOS) bug visible on my laptop. The bug is the following: if the _PPC (Performance Present Capabilities) optional ACPI object is queried /after/ bootup then the BIOS reports an incorrect value of '2'. My laptop (Lenovo T60) has the following performance states supported: 0: 1833000 1: 1333000 2: 1000000 Per ACPI specification, a _PPC value of '0' means that all 3 performance states are usable. A _PPC value of '1' means states 1 .. 2 are usable, a value of '2' means only state '2' (slowest) is usable. now, the _PPC object is optional, and it also comes with notification. Furthermore, when a CPU object is initialized, the _PPC object is initialized as well. So the following evaluation of the _PPC object is superfluous: [<c028ba5f>] acpi_processor_get_platform_limit+0xa1/0xaf [<c028c040>] acpi_processor_register_performance+0x3b9/0x3ef [<c0111a85>] acpi_cpufreq_cpu_init+0xb7/0x596 [<c03dab74>] cpufreq_add_dev+0x160/0x4a8 [<c02bed90>] sysdev_driver_register+0x5a/0xa0 [<c03d9c4c>] cpufreq_register_driver+0xb4/0x176 [<c068ac08>] acpi_cpufreq_init+0xe5/0xeb [<c010056e>] init+0x14f/0x3dd And this is the point where my laptop's BIOS returns the incorrect value of '2'. Note that it has not sent any notification event, so the value is probably not really intentional (possibly spurious), and Windows likely doesnt query it after bootup either. Maybe the value is kept at '2' normally, and is only set to the real value when a true asynchronous event (such as AC plug event, battery switch, etc.) occurs. So i /think/ this is a grey area of the ACPI spec: per the letter of the spec the _PPC value only changes when notified, so there's no reason to query it after the system has booted up. So in my opinion the best (and most compatible) strategy would be to do the change below, and to not evaluate the _PPC object in the acpi_processor_get_performance_info() call, but only evaluate it if _PPC is present during CPU object init, or if it's notified during an asynchronous event. This change is more permissive than the previous logic, so it definitely shouldnt break any existing system. This also happens to fix my laptop, which is merrily chugging along at 1.83 GHz now. Yay!

If a SPI master device exists, udev (udevtrigger) causes kernel crash, due to wrong kobj pointer in kobject_uevent_env(). This problem was not in 2.6.19. The backtrace (on MIPS) was: [<8024db6c>] kobject_uevent_env+0x54c/0x5e8 [<802a8264>] store_uevent+0x1c/0x3c (in drivers/class.c) [<801cb14c>] subsys_attr_store+0x2c/0x50 [<801cb80c>] flush_write_buffer+0x38/0x5c [<801cb900>] sysfs_write_file+0xd0/0x190 [<80181444>] vfs_write+0xc4/0x1a0 [<80181cdc>] sys_write+0x54/0xa0 [<8010dae4>] stack_done+0x20/0x3c flush_write_buffer() passes kobject of spi_master_class.subsys to subsys_addr_store(), then subsys_addr_store() passes a pointer to a struct subsystem to store_uevent() which expects a pointer to a struct class_device. The problem seems subsys_attr_store() called instead of class_device_attr_store(). This mismatch was caused by commit 3bd0f694, which overrides kset of master class. This made spi_master_class.subsys.kset.ktype NULL so subsys_sysfs_ops is used instead of class_dev_sysfs_ops. The commit was to fix spi_busnum_to_master(). Here is a patch fixes this function in other way, just searching children list of class_device.

This patch fixes ia32 core dumps on x86_64 to include just one phdr for the vDSO vma. Currently it writes a confused format with two phdrs for the address, one without contents and one with. This patch removes the special-case core writing macros for the ia32 vDSO. Instead, it uses VM_ALWAYSDUMP in the vma. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO, consistent with fixed native i386 core dumps.

This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

Check pte permission bits in walk_addr(), instead of scattering the checks all over the code. This has the following benefits: 1. We no longer set the accessed bit for accessed which fail permission checks. 2. Setting the accessed bit is simplified. 3. Under some circumstances, we used to pretend a page fault was fixed when it would actually fail the access checks. This caused an unnecessary vmexit. 4. The error code for guest page faults is now correct. The fix helps netbsd further along booting, and allows kvm to pass the new mmu testsuite.

In __writeback_single_inode(), when we find a locked inode and we're not doing a data-integrity sync, we used to just skip writing entirely, since we didn't want to wait for the inode to unlock. However, there's really no reason to skip writing the data pages, which are likely to be the the bulk of the dirty state anyway (and the main reason why writeback was started for the non-data-integrity case, of course!)

It's not pretty, but it appears that ext3 with data=journal will clean pages without ever actually telling the VM that they are clean. This, in turn, will result in the VM (and balance_dirty_pages() in particular) to never realize that the pages got cleaned, and wait forever for an event that already happened. Technically, this seems to be a problem with ext3 itself, but it used to be hidden by 'try_to_free_buffers()' noticing this situation on its own, and just working around the filesystem problem. This commit re-instates that hack, in order to avoid a regression for the 2.6.20 release. This fixes bugzilla 7844: http://bugzilla.kernel.org/show_bug.cgi?id=7844 Peter Zijlstra points out that we should probably retain the debugging code that this removes from cancel_dirty_page(), and I agree, but for the imminent release we might as well just silence the warning too (since it's not a new bug: anything that triggers that warning has been around forever).

The commit 8e3d8433 ([NET]: MIPS checksum annotations and cleanups) broke 64-bit MIPS. The problem is the commit replaces some unsigned long with __be32. On 64bit MIPS, a __be32 (i.e. unsigned int) value is represented as a sign-extented 32-bit value in a 64-bit argument register. So the address 192.168.0.1 (0xc0a80001) is passed as 0xffffffffc0a80001 to csum_tcpudp_nofold() but the asm code in the function expects 0x00000000c0a80001, therefore it returns a wrong checksum. Explicit cast to unsigned long is needed to drop high 32bit. Signed-off-by: NAtsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
