c9e664f Rafael J. Wysocki 03 December 2010, 21:57:45 UTC PM / Hibernate: Fix memory corruption related to swap There is a problem that swap pages allocated before the creation of a hibernation image can be released and used for storing the contents of different memory pages while the image is being saved. Since the kernel stored in the image doesn't know of that, it causes memory corruption to occur after resume from hibernation, especially on systems with relatively small RAM that need to swap often. This issue can be addressed by keeping the GFP_IOFS bits clear in gfp_allowed_mask during the entire hibernation, including the saving of the image, until the system is finally turned off or the hibernation is aborted. Unfortunately, for this purpose it's necessary to rework the way in which the hibernate and suspend code manipulates gfp_allowed_mask. This change is based on an earlier patch from Hugh Dickins.

9f339ca Bojan Smojver 25 November 2010, 22:41:39 UTC PM / Hibernate: Use async I/O when reading compressed hibernation image This is a fix for reading LZO compressed image using async I/O. Essentially, instead of having just one page into which we keep reading blocks from swap, we allocate enough of them to cover the largest compressed size and then let block I/O pick them all up. Once we have them all (and here we wait), we decompress them, as usual. Obviously, the very first block we still pick up synchronously, because we need to know the size of the lot before we pick up the rest. Also fixed the copyright line, which I've forgotten before.

7b2a69b Eric W. Biederman 05 December 2010, 23:51:21 UTC Revert "vfs: show unreachable paths in getcwd and proc" Because it caused a chroot ttyname regression in 2.6.36. As of 2.6.36 ttyname does not work in a chroot. It has already been reported that screen breaks, and for me this breaks an automated distribution testsuite, that I need to preserve the ability to run the existing binaries on for several more years. glibc 2.11.3 which has a fix for this is not an option. The root cause of this breakage is: commit 8df9d1a4142311c084ffeeacb67cd34d190eff74 Author: Miklos Szeredi <mszeredi@suse.cz> Date: Tue Aug 10 11:41:41 2010 +0200 vfs: show unreachable paths in getcwd and proc Prepend "(unreachable)" to path strings if the path is not reachable from the current root. Two places updated are - the return string from getcwd() - and symlinks under /proc/$PID. Other uses of d_path() are left unchanged (we know that some old software crashes if /proc/mounts is changed).

d16cd29 James Bottomley 02 December 2010, 23:36:47 UTC parisc: fix dino/gsc interrupts The essential problem we're currently having is that dino (and gsc) is a cascaded CPU interrupt. Under the old __do_IRQ() handler, our CPU interrupts basically did an ack followed by an end. In the new scheme, we replaced them with level handlers which do a mask, an ack and then an unmask (but no end). Instead, with the renaming of end to eoi, we actually want to call the percpu flow handlers, because they actually have all the characteristics we want. This patch does the conversion and gets my C360 booting again. Signed-off-by: James Bottomley <James.Bottomley@suse.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca> 04 December 2010, 16:14:32 UTC

7ac760c Artem Bityutskiy 02 December 2010, 04:34:01 UTC UBI: fix corrupted PEB detection for NOR flash My new shiny code for corrupted PEB detection has NOR specific bug. We tread PEB as corrupted and preserve it, if 1. EC header is OK. 2. VID header is corrupted. 3. data area is not "all 0xFFs" In case of NOR we have 'nor_erase_prepare()' quirk, which invalidates the headers before erasing the PEB. And we invalidate first the VID header, and then the EC header. So if a power cut happens after we have invalidated the VID header, but before we have invalidated the EC header, we end up with a PEB which satisfies the above 3 conditions, and the scanning code will treat it as corrupted, and will print scary warnings, wrongly. This patch fixes the issue by firt invalidating the EC header, then invalidating the VID header. In case of power cut inbetween, we still just lose the EC header, and UBI can deal with this situation gracefully. Thanks to Anatolij Gustschin <agust@denx.de> for tracking this down.

33dd94a Nelson Elhage 02 December 2010, 22:31:21 UTC do_exit(): make sure that we run with get_fs() == USER_DS If a user manages to trigger an oops with fs set to KERNEL_DS, fs is not otherwise reset before do_exit(). do_exit may later (via mm_release in fork.c) do a put_user to a user-controlled address, potentially allowing a user to leverage an oops into a controlled write into kernel memory. This is only triggerable in the presence of another bug, but this potentially turns a lot of DoS bugs into privilege escalations, so it's worth fixing. I have proof-of-concept code which uses this bug along with CVE-2010-3849 to write a zero to an arbitrary kernel address, so I've tested that this is not theoretical. A more logical place to put this fix might be when we know an oops has occurred, before we call do_exit(), but that would involve changing every architecture, in multiple places. Let's just stick it in do_exit instead.

64141da Jeremy Fitzhardinge 02 December 2010, 22:31:18 UTC vmalloc: eagerly clear ptes on vunmap On stock 2.6.37-rc4, running: # mount lilith:/export /mnt/lilith # find /mnt/lilith/ -type f -print0 | xargs -0 file crashes the machine fairly quickly under Xen. Often it results in oops messages, but the couple of times I tried just now, it just hung quietly and made Xen print some rude messages: (XEN) mm.c:2389:d80 Bad type (saw 7400000000000001 != exp 3000000000000000) for mfn 1d7058 (pfn 18fa7) (XEN) mm.c:964:d80 Attempt to create linear p.t. with write perms (XEN) mm.c:2389:d80 Bad type (saw 7400000000000010 != exp 1000000000000000) for mfn 1d2e04 (pfn 1d1fb) (XEN) mm.c:2965:d80 Error while pinning mfn 1d2e04 Which means the domain tried to map a pagetable page RW, which would allow it to map arbitrary memory, so Xen stopped it. This is because vm_unmap_ram() left some pages mapped in the vmalloc area after NFS had finished with them, and those pages got recycled as pagetable pages while still having these RW aliases. Removing those mappings immediately removes the Xen-visible aliases, and so it has no problem with those pages being reused as pagetable pages. Deferring the TLB flush doesn't upset Xen because it can flush the TLB itself as needed to maintain its invariants. When unmapping a region in the vmalloc space, clear the ptes immediately. There's no point in deferring this because there's no amortization benefit. The TLBs are left dirty, and they are flushed lazily to amortize the cost of the IPIs. This specific motivation for this patch is an oops-causing regression since 2.6.36 when using NFS under Xen, triggered by the NFS client's use of vm_map_ram() introduced in 56e4ebf877b60 ("NFS: readdir with vmapped pages") . XFS also uses vm_map_ram() and could cause similar problems.

In other words, writing to the high bank for a single GPIO bit will clear every other GPIO bit (but only sometimes after a suspend). The workaround described is obvious and simple; do a read-modify-write. This patch does that, and documents why we're doing it.

af42b8d Stefano Stabellini 01 December 2010, 14:51:44 UTC xen: fix MSI setup and teardown for PV on HVM guests When remapping MSIs into pirqs for PV on HVM guests, qemu is responsible for doing the actual mapping and unmapping. We only give qemu the desired pirq number when we ask to do the mapping the first time, after that we should be reading back the pirq number from qemu every time we want to re-enable the MSI. This fixes a bug in xen_hvm_setup_msi_irqs that manifests itself when trying to enable the same MSI for the second time: the old MSI to pirq mapping is still valid at this point but xen_hvm_setup_msi_irqs would try to assign a new pirq anyway. A simple way to reproduce this bug is to assign an MSI capable network card to a PV on HVM guest, if the user brings down the corresponding ethernet interface and up again, Linux would fail to enable MSIs on the device.

This fixes find_unbound_pirq that otherwise would return a number starting from nr_irqs that might very well be out of range in Xen. The symptom of this bug is that when you passthrough an MSI capable pci device to a PV on HVM guest, Linux would fail to enable MSIs on the device.

de25c18 Dave Chinner 30 November 2010, 04:15:46 UTC xfs: avoid moving stale inodes in the AIL When an inode has been marked stale because the cluster is being freed, we don't want to (re-)insert this inode into the AIL. There is a race condition where the cluster buffer may be unpinned before the inode is inserted into the AIL during transaction committed processing. If the buffer is unpinned before the inode item has been committed and inserted, then it is possible for the buffer to be released and hence processthe stale inode callbacks before the inode is inserted into the AIL. In this case, we then insert a clean, stale inode into the AIL which will never get removed by an IO completion. It will, however, get reclaimed and that triggers an assert in xfs_inode_free() complaining about freeing an inode still in the AIL. This race can be avoided by not moving stale inodes forward in the AIL during transaction commit completion processing. This closes the race condition by ensuring we never insert clean stale inodes into the AIL. It is safe to do this because a dirty stale inode, by definition, must already be in the AIL.

309c848 Dave Chinner 30 November 2010, 04:16:02 UTC xfs: delayed alloc blocks beyond EOF are valid after writeback There is an assumption in the parts of XFS that flushing a dirty file will make all the delayed allocation blocks disappear from an inode. That is, that after calling xfs_flush_pages() then ip->i_delayed_blks will be zero. This is an invalid assumption as we may have specualtive preallocation beyond EOF and they are recorded in ip->i_delayed_blks. A flush of the dirty pages of an inode will not change the state of these blocks beyond EOF, so a non-zero deeelalloc block count after a flush is valid. The bmap code has an invalid ASSERT() that needs to be removed, and the swapext code has a bug in that while it swaps the data forks around, it fails to swap the i_delayed_blks counter associated with the fork and hence can get the block accounting wrong.

90810b9 Dave Chinner 30 November 2010, 04:16:16 UTC xfs: push stale, pinned buffers on trylock failures As reported by Nick Piggin, XFS is suffering from long pauses under highly concurrent workloads when hosted on ramdisks. The problem is that an inode buffer is stuck in the pinned state in memory and as a result either the inode buffer or one of the inodes within the buffer is stopping the tail of the log from being moved forward. The system remains in this state until a periodic log force issued by xfssyncd causes the buffer to be unpinned. The main problem is that these are stale buffers, and are hence held locked until the transaction/checkpoint that marked them state has been committed to disk. When the filesystem gets into this state, only the xfssyncd can cause the async transactions to be committed to disk and hence unpin the inode buffer. This problem was encountered when scaling the busy extent list, but only the blocking lock interface was fixed to solve the problem. Extend the same fix to the buffer trylock operations - if we fail to lock a pinned, stale buffer, then force the log immediately so that when the next attempt to lock it comes around, it will have been unpinned.

c726de4 Dave Chinner 30 November 2010, 04:14:39 UTC xfs: fix failed write truncation handling. Since the move to the new truncate sequence we call xfs_setattr to truncate down excessively instanciated blocks. As shown by the testcase in kernel.org BZ #22452 that doesn't work too well. Due to the confusion of the internal inode size, and the VFS inode i_size it zeroes data that it shouldn't. But full blown truncate seems like overkill here. We only instanciate delayed allocations in the write path, and given that we never released the iolock we can't have converted them to real allocations yet either. The only nasty case is pre-existing preallocation which we need to skip. We already do this for page discard during writeback, so make the delayed allocation block punching a generic function and call it from the failed write path as well as xfs_aops_discard_page. The callers are responsible for ensuring that partial blocks are not truncated away, and that they hold the ilock. Based on a fix originally from Christoph Hellwig. This version used filesystem blocks as the range unit. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> 01 December 2010, 13:40:19 UTC

114279b Oleg Nesterov 30 November 2010, 19:56:02 UTC exec: copy-and-paste the fixes into compat_do_execve() paths Note: this patch targets 2.6.37 and tries to be as simple as possible. That is why it adds more copy-and-paste horror into fs/compat.c and uglifies fs/exec.c, this will be cleanuped later. compat_copy_strings() plays with bprm->vma/mm directly and thus has two problems: it lacks the RLIMIT_STACK check and argv/envp memory is not visible to oom killer. Export acct_arg_size() and get_arg_page(), change compat_copy_strings() to use get_arg_page(), change compat_do_execve() to do acct_arg_size(0) as do_execve() does. Add the fatal_signal_pending/cond_resched checks into compat_count() and compat_copy_strings(), this matches the code in fs/exec.c and certainly makes sense.
