df37bd1 Phillip Lougher 23 April 2010, 17:18:11 UTC initramfs: handle unrecognised decompressor when unpacking The unpack routine fails to handle the decompress_method() returning unrecognised decompressor (compress_name == NULL). This results in the routine looping eventually oopsing on an out of bounds memory access. Note this bug is usually hidden, only triggering on trailing junk after one or more correct compressed blocks. The case of the compressed archive being complete junk is (by accident?) caught by the if (state != Reset) check because state is initialised to Start, but not updated due to the decompressor not having been called. Obviously if the junk is trailing a correctly decompressed buffer, state == Reset from the previous call to the decompressor.

453dc65 Dmitry Torokhov 23 April 2010, 17:18:08 UTC VMware Balloon driver This is a standalone version of VMware Balloon driver. Ballooning is a technique that allows hypervisor dynamically limit the amount of memory available to the guest (with guest cooperation). In the overcommit scenario, when hypervisor set detects that it needs to shuffle some memory, it instructs the driver to allocate certain number of pages, and the underlying memory gets returned to the hypervisor. Later hypervisor may return memory to the guest by reattaching memory to the pageframes and instructing the driver to "deflate" balloon. We are submitting a standalone driver because KVM maintainer (Avi Kivity) expressed opinion (rightly) that our transport does not fit well into virtqueue paradigm and thus it does not make much sense to integrate with virtio. There were also some concerns whether current ballooning technique is the right thing. If there appears a better framework to achieve this we are prepared to evaluate and switch to using it, but in the meantime we'd like to get this driver upstream. We want to get the driver accepted in distributions so that users do not have to deal with an out-of-tree module and many distributions have "upstream first" requirement. The driver has been shipping for a number of years and users running on VMware platform will have it installed as part of VMware Tools even if it will not come from a distribution, thus there should not be additional risk in pulling the driver into mainline. The driver will only activate if host is VMware so everyone else should not be affected at all.

b8af67e Anton Blanchard 23 April 2010, 17:18:06 UTC fs/block_dev.c: fix performance regression in O_DIRECT|O_SYNC writes to block devices We are seeing a large regression in database performance on recent kernels. The database opens a block device with O_DIRECT|O_SYNC and a number of threads write to different regions of the file at the same time. A simple test case is below. I haven't defined DEVICE since getting it wrong will destroy your data :) On an 3 disk LVM with a 64k chunk size we see about 17MB/sec and only a few threads in IO wait: procs -----io---- -system-- -----cpu------ r b bi bo in cs us sy id wa st 0 3 0 16170 656 2259 0 0 86 14 0 0 2 0 16704 695 2408 0 0 92 8 0 0 2 0 17308 744 2653 0 0 86 14 0 0 2 0 17933 759 2777 0 0 89 10 0 Most threads are blocking in vfs_fsync_range, which has: mutex_lock(&mapping->host->i_mutex); err = fop->fsync(file, dentry, datasync); if (!ret) ret = err; mutex_unlock(&mapping->host->i_mutex); commit 148f948ba877f4d3cdef036b1ff6d9f68986706a (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) offers some explanation of what is going on: Use these new helpers for syncing from generic VFS functions. This makes O_SYNC writes to block devices acquire i_mutex for syncing. If we really care about this, we can make block_fsync() drop the i_mutex and reacquire it before it returns. Thanks Jan for such a good commit message! As well as dropping i_mutex, Christoph suggests we should remove the call to sync_blockdev(): > sync_blockdev is an overcomplicated alias for filemap_write_and_wait on > the block device inode, which is exactly what we did just before calling > into ->fsync The patch below incorporates both suggestions.

ccdb400 Albin Tonnerre 23 April 2010, 17:17:58 UTC lib: fix the use of LZO to decompress initramfs images This patch fixes 2 issues with the LZO decompressor: - It doesn't handle the case where a block isn't compressed at all. In this case, calling lzo1x_decompress_safe will fail, so we need to just use memcpy() instead (the upstream LZO code does something similar) - Since commit 54291362d2a5738e1b0495df2abcb9e6b0563a3f ("initramfs: add missing decompressor error check") , the decompressor return code is checked in the init/initramfs.c The LZO decompressor didn't return the expected value, causing the initramfs code to falsely believe a decompression error occured Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: bert schulze <spambemyguest@googlemail.com> Cc: "H.

23be746 Mel Gorman 23 April 2010, 17:17:56 UTC hugetlb: fix infinite loop in get_futex_key() when backed by huge pages If a futex key happens to be located within a huge page mapped MAP_PRIVATE, get_futex_key() can go into an infinite loop waiting for a page->mapping that will never exist. See https://bugzilla.redhat.com/show_bug.cgi?id=552257 for more details about the problem. This patch makes page->mapping a poisoned value that includes PAGE_MAPPING_ANON mapped MAP_PRIVATE. This is enough for futex to continue but because of PAGE_MAPPING_ANON, the poisoned value is not dereferenced or used by futex. No other part of the VM should be dereferencing the page->mapping of a hugetlbfs page as its page cache is not on the LRU. This patch fixes the problem with the test case described in the bugzilla.

8a3bdfe Thomas Gerlach 23 April 2010, 17:17:50 UTC drivers/video/efifb.c: support framebuffer for NVIDIA 9400M in MacBook Pro 5,1 Description of patch: --------------------- This is a patch for the EFI framebuffer driver to enable the framebuffer of the NVIDIA 9400M as found in MacBook Pro (MBP) 5,1 and up. The framebuffer of the NVIDIA graphic cards are located at the following addresses in memory: 9400M: 0xC0010000 9600M GT: 0xB0030000 The patch delivered right here only provides the memory location of the framebuffer of the 9400M device. The 9600M GT is not covered. It is assumed that the 9400M is used when powered up the MBP. The information which device is currently powered and in use is stored in the 64 bytes large EFI variable "gpu-power-prefs". More specifically, byte 0x3B indicates whether 9600M GT (0x00) or 9400M (0x01) is online. The PCI bus IDs are the following: 9400M: PCI 03:00:00 9600M GT: PCI 02:00:00 The EFI variables can be easily read-out and manipulated with "rEFIt", an MBP specific bootloader tool. For more information on how handle rEFIt and EFI variables please consult "http://refit.sourceforge.net" and "http://ubuntuforums.org/archive/index.php/t-1076879.html". IMPORTANT NOTE: The information on how to activate the 9400M device given at "ubuntuforums.org" is not correct, since it states gpu-power-prefs[0x3B] = 0x00 -> 9400M (PCI 02:00:00) gpu-power-prefs[0x3B] = 0x01 -> 9600M GT (PCI 03:00:00) Actually, the assignment of the values and the PCI bus IDs are swapped. Suggestions: ------------ To cover framebuffers of both 9400M and 9600M GT, I would suggest to implement a conditional on "gpu-power-prefs". Depending on the value of byte 0x3B, the according framebuffer is selected. However, this requires kernel access to the EFI variables.

fb2162d Jeff Mahoney 23 April 2010, 17:17:41 UTC reiserfs: fix corruption during shrinking of xattrs Commit 48b32a3553a54740d236b79a90f20147a25875e3 ("reiserfs: use generic xattr handlers") introduced a problem that causes corruption when extended attributes are replaced with a smaller value. The issue is that the reiserfs_setattr to shrink the xattr file was moved from before the write to after the write. The root issue has always been in the reiserfs xattr code, but was papered over by the fact that in the shrink case, the file would just be expanded again while the xattr was written. The end result is that the last 8 bytes of xattr data are lost. This patch fixes it to use new_size.

cac36f7 Jeff Mahoney 23 April 2010, 17:17:37 UTC reiserfs: fix permissions on .reiserfs_priv Commit 677c9b2e393a0cd203bd54e9c18b012b2c73305a ("reiserfs: remove privroot hiding in lookup") removed the magic from the lookup code to hide the .reiserfs_priv directory since it was getting loaded at mount-time instead. The intent was that the entry would be hidden from the user via a poisoned d_compare, but this was faulty. This introduced a security issue where unprivileged users could access and modify extended attributes or ACLs belonging to other users, including root. This patch resolves the issue by properly hiding .reiserfs_priv. This was the intent of the xattr poisoning code, but it appears to have never worked as expected. This is fixed by using d_revalidate instead of d_compare. This patch makes -oexpose_privroot a no-op. I'm fine leaving it this way. The effort involved in working out the corner cases wrt permissions and caching outweigh the benefit of the feature.

Due to this erratum, if a code fetch uses this PDE before the TLB entry for the large page is invalidated then it may fetch from a different physical address than specified by either the old large page translation or the new 4-KByte page translation. This erratum may also cause speculative code fetches from incorrect addresses." [http://download.intel.com/design/processor/specupdt/319536.pdf] Where as commit 211b3d03c7400f48a781977a50104c9d12f4e229 seems to workaround errata AAH41 (mixed 4K TLBs) it reduces the window of opportunity for the bug to occur and does not totally remove it. This patch disables mixed 4K/4MB page tables totally avoiding the page splitting and not tripping this processor issue. This is based on an original patch by Colin King.

7ce5a2b H. Peter Anvin 23 April 2010, 23:17:40 UTC x86-64: Clear a 64-bit FS/GS base on fork if selector is nonzero When we do a thread switch, we clear the outgoing FS/GS base if the corresponding selector is nonzero. This is taken by __switch_to() as an entry invariant; it does not verify that it is true on entry. However, copy_thread() doesn't enforce this constraint, which can result in inconsistent results after fork(). Make copy_thread() match the behavior of __switch_to().

571dc79 Alan Stern 09 April 2010, 20:03:43 UTC USB: put claimed interfaces in the "suspended" state This patch (as1370) fixes a bug in the USB runtime power management code. When a driver claims an interface, it doesn't expect to need to call usb_autopm_get_interface() or usb_autopm_put_interface() for runtime PM to work. Runtime PM can be controlled by the driver's primary interface; the additional interfaces it claims shouldn't interfere. As things stand, the claimed interfaces will prevent the device from autosuspending. To fix this problem, the patch sets interfaces to the suspended state when they are claimed. Also, although in theory this shouldn't matter, the patch changes the suspend code so that interfaces are suspended in reverse order from detection and resuming. This is how the PM core works, and we ought to use the same approach.

5f677f1 Alan Stern 02 April 2010, 17:20:11 UTC USB: fix remote wakeup settings during system sleep This patch (as1363) changes the way USB remote wakeup is handled during system sleeps. It won't be enabled unless an interface driver specifically needs it. Also, it won't be enabled during the FREEZE or QUIESCE phases of hibernation, when the system doesn't respond to wakeup events anyway. Finally, if the device is already runtime-suspended with remote wakeup enabled, but wakeup is supposed to be disabled for the system sleep, the device gets woken up so that it can be suspended again with the proper wakeup setting. This will fix problems people have reported with certain USB webcams that generate wakeup requests when they shouldn't, and as a result cause system suspends to fail.
