xfs: update for v3.13-rc1
For 3.13-rc1 we have an eclectic assortment of bugfixes, cleanups, and refactoring. Bugfixes that stand out are the fix for the AGF/AGI deadlock, incore extent list fixes, verifier fixes for v4 superblocks and growfs, and memory leaks. There are some asserts, warnings, and strings that were cleaned up. There was further rearrangement of code to make libxfs and the kernel sync up more easily, differences between v2 and v3 directory code were abstracted using an ops vector, xfs_inactive was reworked, and the preallocation/hole punching code was refactored. - simplify kmem_zone_zalloc - add traces for AGF/AGI read ops - add additional AIL traces - fix xfs_remove AGF vs AGI deadlock - fix the extent count of new incore extent page in the indirection array - don't fail bad secondary superblocks verification on v4 filesystems due to unzeroed bits after v4 fields - fix possible NULL dereference in xlog_verify_iclog - remove redundant assert in xfs_dir2_leafn_split - prevent stack overflows from page cache allocation - fix some sparse warnings - fix directory block format verifier to check the leaf entry count - abstract the differences in dir2/dir3 via an ops vector - continue process of reorganization to make libxfs/kernel code merges easier - refactor the preallocation and hole punching code - fix for growfs and verifiers - remove unnecessary scary corruption error when probing non-xfs filesystems - remove extra newlines from strings passed to printk - prevent deadlock trying to cover an active log - rework xfs_inactive() - add the inode directory type support to XFS_IOC_FSGEOM - cleanup (remove) usage of is_bad_inode - fix miscalculation in xfs_iext_realloc_direct which results in oversized direct extent list - remove unnecessary count arg to xfs_iomap_write_allocate - fix memory leak in xlog_recover_add_to_trans - check superblock instead of block magic to determine if dtype field is present - fix lockdep annotation due to project quotas - fix regression in xfs_node_toosmall which can lead to incorrect directory btree node collapse - make log recovery verify filesystem uuid of recovering blocks - fix XFS_IOC_FREE_EOFBLOCKS definition - remove invalid assert in xfs_inode_free - fix for AIL lock regression -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJShBL7AAoJENaLyazVq6ZOaRwP/1B3QkWxFArRSD4wl15oBxpN Zv6D7woTmAvON87OIG4m67gyTr5/yNrPy8bg6Qw4YoL6lHTgle+RDUaKhgnsODoX Gd/oOiKCBqGfe93zs2fzIQzZ+yn+xdXr+q8uyEwEe8QHK6/wg6lEHNNae8VXEBlO 20ec4b0U9dxoOJyG8nJNdytI++jp3TWzmZGpmLwisRogt4b86JM+QRhKFOe18AeI c9ky0uQmOQ6gX6h1VKN1L1u66GpTtFgj8XqPp/V6D8xHb1XGNiutDAKD7Mt/Rcgf njQsky2lXSQIuOnhyS1+lPvR8x19srs6UdnxcWdJvvwsICb14ZHEsZQA7M1bkLnw zNYtwn5RSneVSdjUZ+55dU1oDfTw2fxRHmKcm3bKrJCG7aOcH5vhEKs6HS0eVZAW 4AcjThA43UpcEv47sghd7WJ+hFc4tKDVh9BOLUNi9zlkltVdP6WmWduMco0mRNeJ gd++CFRv9R3cQ0UUNsNMGQ9a8k/TW5uHYRsfX2IRBcgXQD2Ip1HBGLGSft2/JA4G U53mM08RntInGKctp1PjJea74QPJrYT7wBMlBl917tmnZ59i20nDs/OfeD2Dsnod 9ekK5J7cMGHdWnQ3+o2b9Awuypcl+d9vdNKgNmNVTPlptfkI5OjJ5+BhqScyDw7m LJ1JmPIPIJF7vdIqBJWL =XMd/ -----END PGP SIGNATURE----- Merge tag 'xfs-for-linus-v3.13-rc1' of git://oss.sgi.com/xfs/xfs Pull xfs update from Ben Myers: "For 3.13-rc1 we have an eclectic assortment of bugfixes, cleanups, and refactoring.

A set of device-mapper changes for 3.13.
Improve reliability of buffer allocations for dm messages with a small number of arguments, a couple path group initialization fixes for dm multipath, a fix for resizing a dm array, various fixes and optimizations for dm cache, a fix for device mapper's Kconfig menu indentation. Features added include: - dm crypt support for activating legacy CBC TrueCrypt containers (useful for forensics of these old TCRYPT containers) - reduced dm-cache memory requirements for each block in the cache - basic support for shrinking a dm-cache's cache (fast) device - most notably, dm-cache support for managing cache coherency when deploying dm-cache with sophisticated origin volumes (that support hardware snapshots and/or clustering): these changes come in the form of a new passthrough operation mode and a cache block invalidation interface. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQEcBAABAgAGBQJSgt+QAAoJEMUj8QotnQNapcEIALC6U1rmw08PRMSanqg4/aVu pTahzPtai9jXchQV6q5XsglJryrhD9MoNqrZgHd2drdnmEKTKfVX+/iCXGiE4hQ5 I5QUZf5myEXSd60pCgZwNam+VHMuAuSPQW6LWqRTJjDLHixGF+AoHZGxkEsYgj6M p686OOpga1nmT2w072xLIh9z2tsv/tm+UN7GSbyklM+/1ItcXxq+/J8rsuth7IqT k0I60jexq+Q3OaYuJY7vxhdE7PhBCw1fGmtuCcjekqsSVpAdCgDz3FFOEZmyXcUs YLFE3GcclYQpIPjNjVGTLDFHdoIMWdKiibs/ScBUtegqxWvqP7c87YFhbL+VHDM= =lLxo -----END PGP SIGNATURE----- Merge tag 'dm-3.13-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper changes from Mike Snitzer: "A set of device-mapper changes for 3.13.

Merge branch 'for-3.13/core' of git://git.kernel.dk/linux-block
Pull block IO core updates from Jens Axboe: "This is the pull request for the core changes in the block layer for 3.13. It contains: - The new blk-mq request interface. This is a new and more scalable queueing model that marries the best part of the request based interface we currently have (which is fully featured, but scales poorly) and the bio based "interface" which the new drivers for high IOPS devices end up using because it's much faster than the request based one. The bio interface has no block layer support, since it taps into the stack much earlier. This means that drivers end up having to implement a lot of functionality on their own, like tagging, timeout handling, requeue, etc. The blk-mq interface provides all these. Some drivers even provide a switch to select bio or rq and has code to handle both, since things like merging only works in the rq model and hence is faster for some workloads. This is a huge mess. Conversion of these drivers nets us a substantial code reduction. Initial results on converting SCSI to this model even shows an 8x improvement on single queue devices. So while the model was intended to work on the newer multiqueue devices, it has substantial improvements for "classic" hardware as well. This code has gone through extensive testing and development, it's now ready to go. A pull request is coming to convert virtio-blk to this model will be will be coming as well, with more drivers scheduled for 3.14 conversion. - Two blktrace fixes from Jan and Chen Gang. - A plug merge fix from Alireza Haghdoost. - Conversion of __get_cpu_var() from Christoph Lameter. - Fix for sector_div() with 64-bit divider from Geert Uytterhoeven. - A fix for a race between request completion and the timeout handling from Jeff Moyer. This is what caused the merge conflict with blk-mq/core, in case you are looking at that. - A dm stacking fix from Mike Snitzer. - A code consolidation fix and duplicated code removal from Kent Overstreet. - A handful of block bug fixes from Mikulas Patocka, fixing a loop crash and memory corruption on blk cg. - Elevator switch bug fix from Tomoki Sekiyama. A heads-up that I had to rebase this branch. Initially the immutable bio_vecs had been queued up for inclusion, but a week later, it became clear that it wasn't fully cooked yet. So the decision was made to pull this out and postpone it until 3.14. It was a straight forward rebase, just pruning out the immutable series and the later fixes of problems with it. The rest of the patches applied directly and no further changes were made" * 'for-3.13/core' of git://git.kernel.dk/linux-block: (31 commits) block: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO block: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO block: Do not call sector_div() with a 64-bit divisor kernel: trace: blktrace: remove redundent memcpy() in compat_blk_trace_setup() block: Consolidate duplicated bio_trim() implementations block: Use rw_copy_check_uvector() block: Enable sysfs nomerge control for I/O requests in the plug list block: properly stack underlying max_segment_size to DM device elevator: acquire q->sysfs_lock in elevator_change() elevator: Fix a race in elevator switching and md device initialization block: Replace __get_cpu_var uses bdi: test bdi_init failure block: fix a probe argument to blk_register_region loop: fix crash if blk_alloc_queue fails blk-core: Fix memory corruption if blkcg_init_queue fails block: fix race between request completion and timeout handling blktrace: Send BLK_TN_PROCESS events to all running traces blk-mq: don't disallow request merges for req->special being set blk-mq: mq plug list breakage blk-mq: fix for flush deadlock ... |

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King: "Included in this series are: 1. BE8 (modern big endian) changes for ARM from Ben Dooks 2. big.Little support from Nicolas Pitre and Dave Martin 3. support for LPAE systems with all system memory above 4GB 4. Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences. Any errors are likely mine.

Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ... |

sched/numa: Cure update_numa_stats() vs. hotplug
Because we're completely unserialized against hotplug its well possible to try and generate numa stats for an offlined node. Bail out early (and avoid a /0) in this case.

sched/numa: Fix NULL pointer dereference in task_numa_migrate()
The cpusets code can split up the scheduler's domain tree into smaller domains. Some of those smaller domains may not cross NUMA nodes at all, leading to a NULL pointer dereference on the per-cpu sd_numa pointer. Tasks cannot be migrated out of their domain, so the patch also sets p->numa_preferred_nid to whereever they are, to prevent the migration from being retried over and over again.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller: 1) The addition of nftables. No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net.

ipc, msg: fix message length check for negative values
On 64 bit systems the test for negative message sizes is bogus as the size, which may be positive when evaluated as a long, will get truncated to an int when passed to load_msg(). So a long might very well contain a positive value but when truncated to an int it would become negative. That in combination with a small negative value of msg_ctlmax (which will be promoted to an unsigned type for the comparison against msgsz, making it a big positive value and therefore make it pass the check) will lead to two problems: 1/ The kmalloc() call in alloc_msg() will allocate a too small buffer as the addition of alen is effectively a subtraction. 2/ The copy_from_user() call in load_msg() will first overflow the buffer with userland data and then, when the userland access generates an access violation, the fixup handler copy_user_handle_tail() will try to fill the remainder with zeros -- roughly 4GB. That almost instantly results in a system crash or reset. ,-[ Reproducer (needs to be run as root) ]-- | #include <sys/stat.h> | #include <sys/msg.h> | #include <unistd.h> | #include <fcntl.h> | | int main(void) { | long msg = 1; | int fd; | | fd = open("/proc/sys/kernel/msgmax", O_WRONLY); | write(fd, "-1", 2); | close(fd); | | msgsnd(0, &msg, 0xfffffff0, IPC_NOWAIT); | | return 0; | } '--- Fix the issue by preventing msgsz from getting truncated by consistently using size_t for the message length. This way the size checks in do_msgsnd() could still be passed with a negative value for msg_ctlmax but we would fail on the buffer allocation in that case and error out. Also change the type of m_ts from int to size_t to avoid similar nastiness in other code paths -- it is used in similar constructs, i.e. signed vs. unsigned checks. It should never become negative under normal circumstances, though. Setting msg_ctlmax to a negative value is an odd configuration and should be prevented. As that might break existing userland, it will be handled in a separate commit so it could easily be reverted and reworked without reintroducing the above described bug. Hardening mechanisms for user copy operations would have catched that bug early -- e.g. checking slab object sizes on user copy operations as the usercopy feature of the PaX patch does. Or, for that matter, detect the long vs. int sign change due to truncation, as the size overflow plugin of the very same patch does.

devpts: plug the memory leak in kill_sb
When devpts is unmounted, there may be a no-longer-used IDR tree hanging off the superblock we are about to kill. This needs to be cleaned up before destroying the SB. The leak is usually not a big deal because unmounting devpts is typically done when shutting down the whole machine. However, shutting down an LXC container instead of a physical machine exposes the problem (the garbage is detectable with kmemleak).

./Makefile: export initial ramdisk compression config option
Make menuconfig allows one to choose compression format of an initial ramdisk image. But this choice does not result in duly compressed ramdisk image. Because - $ make install - does not pass on the selected compression choice to the dracut(8) tool, which creates the initramfs file. dracut(8) generates the image with the default compression, ie. gzip(1). This patch exports the selected compression option to a sub-shell environment, so that it could be used by dracut(8) tool to generate appropriately compressed initramfs images. There isn't a straightforward way to pass on options to dracut(8) via positional parameters. Because it is indirectly invoked at the end of a $ make install sequence. # make install -> arch/$arch/boot/Makefile -> arch/$arch/boot/install.sh -> /sbing/installkernel ... -> /sbin/new-kernel-pkg ... -> /sbin/dracut ...

init/Kconfig: add option to disable kernel compression
Some ARC users say they can boot faster with without kernel compression. This probably depends on things like the FLASH chip they use etc. Until now, kernel compression can only be disabled by removing "select HAVE_<compression>" lines from the architecture Kconfig. So add the Kconfig logic to permit disabling of kernel compression.

drivers: w1: make w1_slave::flags long to avoid memory corruption
On architectures where long is more then 32 bits, modifying a 32-bit field with set_bit (and other atomic bit operations) may cause bytes following the field to by modified. Because the endianness of the bits within a field is the native endianness of the CPU[1], on big-endian machines, bit number zero is in the last byte of the field. Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit field for holding the flags, this causes bytes beyond the field to be modified. [1] From Documentation/atomic_ops.txt: Native atomic bit operations are defined to operate on objects aligned to the size of an "unsigned long" C data type, and are least of that size. The endianness of the bits within each "unsigned long" are the native endianness of the cpu.
