e6af578 Michael S. Tsirkin 17 November 2011, 15:41:15 UTC virtio-pci: make reset operation safer virtio pci device reset actually just does an I/O write, which in PCI is really posted, that is it can complete on CPU before the device has received it. Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.

0f751e6 Tyler Hicks 23 November 2011, 17:31:24 UTC eCryptfs: Extend array bounds for all filename chars From mhalcrow's original commit message: Characters with ASCII values greater than the size of filename_rev_map[] are valid filename characters. ecryptfs_decode_from_filename() will access kernel memory beyond that array, and ecryptfs_parse_tag_70_packet() will then decrypt those characters. The attacker, using the FNEK of the crafted file, can then re-encrypt the characters to reveal the kernel memory past the end of the filename_rev_map[] array. I expect low security impact since this array is statically allocated in the text area, and the amount of memory past the array that is accessible is limited by the largest possible ASCII filename character. This patch solves the issue reported by mhalcrow but with an implementation suggested by Linus to simply extend the length of filename_rev_map[] to 256. Characters greater than 0x7A are mapped to 0x00, which is how invalid characters less than 0x7A were previously being handled.

32001d6 Tyler Hicks 21 November 2011, 23:31:29 UTC eCryptfs: Flush file in vma close Dirty pages weren't being written back when an mmap'ed eCryptfs file was closed before the mapping was unmapped. Since f_ops->flush() is not called by the munmap() path, the lower file was simply being released. This patch flushes the eCryptfs file in the vm_ops->close() path. https://launchpad.net/bugs/870326 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Cc: stable@kernel.org [2.6.39+] 23 November 2011, 21:40:09 UTC
b59db43 Tyler Hicks 21 November 2011, 23:31:02 UTC eCryptfs: Prevent file create race condition The file creation path prematurely called d_instantiate() and unlock_new_inode() before the eCryptfs inode info was fully allocated and initialized and before the eCryptfs metadata was written to the lower file. This could result in race conditions in subsequent file and inode operations leading to unexpected error conditions or a null pointer dereference while attempting to use the unallocated memory. https://launchpad.net/bugs/813146 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Cc: stable@kernel.org 23 November 2011, 21:39:38 UTC

b4bbb02 Linus Torvalds 22 November 2011, 23:09:20 UTC Revert "of/irq: of_irq_find_parent: check for parent equal to child" This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91. As requested by Ben Herrenschmidt: "This breaks some powerpc platforms at least. The practice of having a node provide an explicit "interrupt-parent" property pointing to itself is an old trick that we've used in the past to allow a device-node to have interrupts routed to different controllers. In that case, the node also contains an interrupt-map, so the node is its own parent, the interrupt resolution hits the map, which then can route each individual interrupt to a different parent." Grant says: "Ah, nuts, yes that is broken then. Yes, please revert the commit and Rob & I will come up with a better solution. Rob, I think it can be done by explicitly checking for np == desc->interrupt_parent in of_irq_init() instead of relying on of_irq_find_parent() returning NULL."

While the logging code is pinning down block groups, there is a bogus WARN_ON we're hitting if the code wasn't able to find an extent in the cache.

dd17994 David Howells 16 August 2011, 14:31:30 UTC VFS: Log the fact that we've given ELOOP rather than creating a loop To prevent an NFS server from being used to create a directory loop in an NFS superblock on the client, the following patch was committed: commit 1836750115f20b774e55c032a3893e8c5bdf41ed Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Jul 12 21:42:24 2011 -0400 Subject: fix loop checks in d_materialise_unique() This causes ELOOP to be reported to anyone trying to access the dentry that would otherwise cause the kernel to complete the loop. However, no indication is given to the caller as to why an operation that ought to work doesn't. The fault is with the kernel, which doesn't want to try and solve the problem as it gets horrendously messy if there's another mountpoint somewhere in the trees being spliced that can't be moved[*]. [*] The real problem is that we don't handle the excision of a subtree that gets moved _out_ of what we can see. This can happen on the server where a directory is merely moved between two other dirs on the same filesystem, but where destination dir is not accessible by the client. So, given the choice to return ELOOP rather than trying to reconfigure the dentry tree, we should give the caller some indication of why they aren't being allowed to make what should be a legitimate request and log a message.

4d479cf Josef Bacik 17 November 2011, 16:34:31 UTC Btrfs: sectorsize align offsets in fiemap We've been hitting BUG()'s in btrfs_cont_expand and btrfs_fallocate and anywhere else that calls btrfs_get_extent while running xfstests 13 in a loop. This is because fiemap is calling btrfs_get_extent with non-sectorsize aligned offsets, which will end up adding mappings that are not sectorsize aligned, which will cause problems in some cases for subsequent calls to btrfs_get_extent for similar areas that are sectorsize aligned. With this patch I ran xfstests 13 in a loop for a couple of hours and didn't hit the problem that I could previously hit in at most 20 minutes.

291c7d2 Josef Bacik 14 November 2011, 18:52:14 UTC Btrfs: wait on caching if we're loading the free space cache We've been hitting panics when running xfstest 13 in a loop for long periods of time. And actually this problem has always existed so we've been hitting these things randomly for a while. Basically what happens is we get a thread coming into the allocator and reading the space cache off of disk and adding the entries to the free space cache as we go. Then we get another thread that comes in and tries to allocate from that block group. Since block_group->cached != BTRFS_CACHE_NO it goes ahead and tries to do the allocation. We do this because if we're doing the old slow way of caching we don't want to hold people up and wait for everything to finish. The problem with this is we could end up discarding the space cache at some arbitrary point in the future, which means we could very well end up allocating space that is either bad, or when the real caching happens it could end up thinking the space isn't in use when it really is and cause all sorts of other problems. The solution is to add a new flag to indicate we are loading the free space cache from disk, and always try to cache the block group if cache->cached != BTRFS_CACHE_FINISHED. That way if we are loading the space cache anybody else who tries to allocate from the block group will have to wait until it's finished to make sure it completes successfully.

In this case, there will be only one bitmap [256, 512] in the temporary bitmaps list, and then setup_cluster_bitmap() won't search bitmap [0, 256]. The cause is, the list is constructed in setup_cluster_no_bitmap(), and only bitmaps with bitmap_entry->offset >= offset will be added into the list, and the very bitmap that convers offset has bitmap_entry->offset <= offset.

But, we have two bugs in the way these are sent down. When doing full commits (not via the tree log), we are sending the barrier down before the last super when it should be going down before the first. In multi-device setups, we should be waiting for the barriers to complete on all devices before writing any of the supers. Both of these bugs can cause corruptions on power failures. We fix it with some new code to send down empty barriers to all devices before writing the first super. Alexandre Oliva found the multi-device bug. Arne Jansen did the async barrier loop.

e70f224 Marek Olšák 24 October 2011, 23:38:45 UTC drm/radeon/kms: add a CS ioctl flag not to rewrite tiling flags in the CS This adds a new optional chunk to the CS ioctl that specifies optional flags to the CS parser. Why this is useful is explained below. Note that some regs no longer need the NOP relocation packet if this feature is enabled. Tested on r300g and r600g with this flag disabled and enabled. Assume there are two contexts sharing the same mipmapped tiled texture. One context wants to render into the first mipmap and the other one wants to render into the last mipmap. As you probably know, the hardware has a MACRO_SWITCH feature, which turns off macro tiling for small mipmaps, but that only applies to samplers. (at least on r300-r500, though later hardware likely behaves the same) So we want to just re-set the tiling flags before rendering (writing packets), right? ... No. The contexts run in parallel, so they may set the tiling flags simultaneously and then fire their command streams also simultaneously. The last one setting the flags wins, the other one loses. Another problem is when one context wants to render into the first and the last mipmap in one CS. Impossible. It must flush before changing tiling flags and do the rendering into the smaller mipmaps in another CS. Yet another problem is that writing copy_blit in userspace would be a mess involving re-setting tiling flags to please the kernel, and causing races with other contexts at the same time. The only way out of this is to send tiling flags with each CS, ideally with each relocation. But we already do that through the registers. So let's just use what we have in the registers.

That code has since been removed, but probably should never have been added in the first place: we don't want HPAGE_SIZE to act like PAGE_SIZE for code that is working with hugepages, for example, when the dependency on CONFIG_HUGETLB_PAGE has not been fulfilled. Because hugepage size can differ from architecture to architecture, each is required to have their own definitions for both HPAGE_MASK and HPAGE_SIZE. This is always done in arch/*/include/asm/page.h. So, just remove the dummy and dangerous definitions since they are no longer needed and reveals the correct dependencies. Tested on architectures using the definitions with allyesconfig: x86 (even with thp), hppa, mips, powerpc, s390, sh3, sh4, sparc, and sparc64, and with defconfig on ia64.

But while doing that, the hibernation test TEST_FREEZER and the test mode HIBERNATION_TESTPROC were not moved accordingly. As a result, when using these test modes, it only goes upto the freezing of userspace and exits, when in fact it should go till the complete end of task freezing stage, namely the freezing of kernel threads as well. So, move these points of exit to appropriate places so that freezing of kernel threads is also tested while using these test harnesses. Signed-off-by: Srivatsa S.

It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

When called while characters are being transmitted can cause the FTDI chip to corrupt the serial port bit stream output by stalling the output half a bit during the output of a character. Simple fix by skipping this setting if the baud rate/data bits/parity are unchanged. Signed-off-by: Andrew Worsley <amworsley@gmail.com> Cc: stable <stable@vger.kernel.org> ---- I had a brief run with strace on the getty and it was doing ioctl()s on each call but it didn't look relavant to the problem. I think the issue is that XON/XOFF flow control was being implmented via hardware - for the ixoff to allow the user to use XON/XOFF to control output. Unfortunately it would send 3 Control URBs updating all of the settings after each piece of input I am trying to work around the issue of gmail messing with the tab/spacing by submitting via SMTP via gmail which I believe should fix the issue.

c618759 Alan Stern 17 November 2011, 21:41:45 UTC OHCI: final fix for NVIDIA problems (I hope) Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.
