2011-12-08memblock: Kill memblock_init()Tejun Heo
memblock_init() initializes arrays for regions and memblock itself; however, all these can be done with struct initializers and memblock_init() can be removed. This patch kills memblock_init() and initializes memblock with struct initializer. The only difference is that the first dummy entries don't have .nid set to MAX_NUMNODES initially. This doesn't cause any behavior difference.

2011-12-08memblock: Kill sentinel entries at the end of static region arraysTejun Heo
memblock no longer depends on having one more entry at the end during addition making the sentinel entries at the end of region arrays not too useful. Remove the sentinels.

2011-12-08memblock: Make memblock_{add|remove|free|reserve}() return int and update ↵Tejun Heo
prototypes memblock_{add|remove|free|reserve}() return either 0 or -errno but had long as return type. Chage it to int. Also, drop 'extern' from all prototypes in memblock.h - they are unnecessary and used inconsistently (especially if mm.h is included in the picture).

2011-12-08memblock: Fix include breakages caused by 24aa07882bTejun Heo
24aa07882b (memblock, x86: Replace memblock_x86_reserve/free_range() with generic ones) removed arch/x86/include/asm/memblock.h and dropped its inclusion from include/linux/memblock.h which breaks other architectures which depended on the generic memblock.h pulling in the arch specific one. However, the proper fix isn't adding back the asm inclusion. memblock doesn't have any arch dependent part and doesn't need arch specific header file and asm/memblock.h files are either practically empty or contain mostly unrelated arch specific stuff. * In microblaze, sh, powerpc, sparc and openrisc, asm/memblock.h is either empty or just contains unused MEMBLOCK_DBG() macro. Remove them. * In arm and unicore32, asm/memblock.h contains arch specific stuff. Include it directly from its users. It might be a good idea to rename the header file to avoid confusion.

2011-11-24virtio-pci: make reset operation saferMichael S. Tsirkin
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.

2011-11-23eCryptfs: Extend array bounds for all filename charsTyler Hicks
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.

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.

2011-11-23eCryptfs: Prevent file create race conditionTyler Hicks
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

2011-11-22Revert "of/irq: of_irq_find_parent: check for parent equal to child"Linus Torvalds
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."
