2010-12-02do_exit(): make sure that we run with get_fs() == USER_DSNelson Elhage
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.

2010-12-02vmalloc: eagerly clear ptes on vunmapJeremy Fitzhardinge
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.

2010-12-02cs5535-gpio: apply CS5536 errata workaround for GPIOsAndres Salomon
The AMD Geode CS5536 Companion Device Silicon Revision B1 Specification Update mentions the follow as issue #36: "Atomic write transactions to the atomic GPIO High Bank Feature Bit registers should only affect the bits selected [...]" "after Suspend, an atomic write transaction [...] will clear all non-selected bits of the accessed register." 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.

2010-12-02reiserfs: don't acquire lock recursively in reiserfs_acl_chmodFrederic Weisbecker
reiserfs_acl_chmod() can be called by reiserfs_set_attr() and then take the reiserfs lock a second time. Thereafter it may call journal_begin() that definitely requires the lock not to be nested in order to release it before taking the journal mutex because the reiserfs lock depends on the journal mutex already. So, aviod nesting the lock in reiserfs_acl_chmod().

2010-12-02cifs: add attribute cache timeout (actimeo) tunableSuresh Jayaraman
Currently, the attribute cache timeout for CIFS is hardcoded to 1 second. This means that the client might have to issue a QPATHINFO/QFILEINFO call every 1 second to verify if something has changes, which seems too expensive. On the other hand, if the timeout is hardcoded to a higher value, workloads that expect strict cache coherency might see unexpected results. Making attribute cache timeout as a tunable will allow us to make a tradeoff between performance and cache metadata correctness depending on the application/workload needs. Add 'actimeo' tunable that can be used to tune the attribute cache timeout. The default timeout is set to 1 second. Also, display actimeo option value in /proc/mounts. It appears to me that 'actimeo' and the proposed (but not yet merged) 'strictcache' option cannot coexist, so care must be taken that we reset the other option if one of them is set.

2010-12-02ftrace: Have recordmcount honor endianness in fn_ELF_R_INFOJohn Reiser
It looks to me like the change which introduced "virtual functions" forgot about cross-platform endianness. Thank you to Arnaud for supplying before+after data files do_mounts*.o. This fixes a MIPS build failure triggered by recordmcount.

2010-12-02NFS: Fix a memory leak in nfs_readdirTrond Myklebust
We need to ensure that the entries in the nfs_cache_array get cleared when the page is removed from the page cache. To do so, we use the freepage address_space operation. Change nfs_readdir_clear_array to use kmap_atomic(), so that the function can be safely called from all contexts. Finally, modify the cache_page_release helper to call nfs_readdir_clear_array directly, when dealing with an anonymous page from 'uncached_readdir'.

2010-12-02Call the filesystem back whenever a page is removed from the page cacheLinus Torvalds
NFS needs to be able to release objects that are stored in the page cache once the page itself is no longer visible from the page cache. This patch adds a callback to the address space operations that allows filesystems to perform page cleanups once the page has been removed from the page cache. Original patch by: Linus Torvalds <torvalds@linux-foundation.org> [trondmy: cover the cases of invalidate_inode_pages2() and truncate_inode_pages()] Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
