Pull Writeback error handling updates from Jeff Layton: "This pile represents the bulk of the writeback error handling fixes that I have for this cycle. Some of the earlier patches in this pile may look trivial but they are prerequisites for later patches in the series. The aim of this set is to improve how we track and report writeback errors to userland. Most applications that care about data integrity will periodically call fsync/fdatasync/msync to ensure that their writes have made it to the backing store. For a very long time, we have tracked writeback errors using two flags in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a writeback error occurs (via mapping_set_error) and are cleared as a side-effect of filemap_check_errors (as you noted yesterday). This model really sucks for userland. Only the first task to call fsync (or msync or fdatasync) will see the error. Any subsequent task calling fsync on a file will get back 0 (unless another writeback error occurs in the interim). If I have several tasks writing to a file and calling fsync to ensure that their writes got stored, then I need to have them coordinate with one another. That's difficult enough, but in a world of containerized setups that coordination may even not be possible. But wait...it gets worse! The calls to filemap_check_errors can be buried pretty far down in the call stack, and there are internal callers of filemap_write_and_wait and the like that also end up clearing those errors. Many of those callers ignore the error return from that function or return it to userland at nonsensical times (e.g. truncate() or stat()). If I get back -EIO on a truncate, there is no reason to think that it was because some previous writeback failed, and a subsequent fsync() will (incorrectly) return 0. This pile aims to do three things: 1) ensure that when a writeback error occurs that that error will be reported to userland on a subsequent fsync/fdatasync/msync call, regardless of what internal callers are doing 2) report writeback errors on all file descriptions that were open at the time that the error occurred. This is a user-visible change, but I think most applications are written to assume this behavior anyway. Those that aren't are unlikely to be hurt by it. 3) document what filesystems should do when there is a writeback error. Today, there is very little consistency between them, and a lot of cargo-cult copying. We need to make it very clear what filesystems should do in this situation. To achieve this, the set adds a new data type (errseq_t) and then builds new writeback error tracking infrastructure around that. Once all of that is in place, we change the filesystems to use the new infrastructure for reporting wb errors to userland. Note that this is just the initial foray into cleaning up this mess. There is a lot of work remaining here: 1) convert the rest of the filesystems in a similar fashion. Once the initial set is in, then I think most other fs' will be fairly simple to convert. Hopefully most of those can in via individual filesystem trees. 2) convert internal waiters on writeback to use errseq_t for detecting errors instead of relying on the AS_* flags. I have some draft patches for this for ext4, but they are not quite ready for prime time yet. This was a discussion topic this year at LSF/MM too. If you're interested in the gory details, LWN has some good articles about this: https://lwn.net/Articles/718734/ https://lwn.net/Articles/724307/" * tag 'for-linus-v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: btrfs: minimal conversion to errseq_t writeback error reporting on fsync xfs: minimal conversion to errseq_t writeback error reporting ext4: use errseq_t based error handling for reporting data writeback errors fs: convert __generic_file_fsync to use errseq_t based reporting block: convert to errseq_t based writeback error tracking dax: set errors in mapping when writeback fails Documentation: flesh out the section in vfs.txt on storing and reporting writeback errors mm: set both AS_EIO/AS_ENOSPC and errseq_t in mapping_set_error fs: new infrastructure for writeback error handling and reporting lib: add errseq_t type and infrastructure for handling it mm: don't TestClearPageError in __filemap_fdatawait_range mm: clear AS_EIO/AS_ENOSPC when writeback initiation fails jbd2: don't clear and reset errors after waiting on writeback buffer: set errors in mapping at the time that the error occurs fs: check for writeback errors after syncing out buffers in generic_file_fsync buffer: use mapping_set_error instead of setting the flag mm: fix mapping_set_error call in me_pagecache_dirty

Pull Kbuild thin archives updates from Masahiro Yamada: "Thin archives migration by Nicholas Piggin. THIN_ARCHIVES has been available for a while as an optional feature only for PowerPC architecture, but we do not need two different intermediate-artifact schemes. Using thin archives instead of conventional incremental linking has various advantages: - save disk space for builds - speed-up building a little - fix some link issues (for example, allyesconfig on ARM) due to more flexibility for the final linking - work better with dead code elimination we are planning As discussed before, this migration has been done unconditionally so that any problems caused by this will show up with "git bisect".

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.13 series. Some administrativa: I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO driver coming in through this tree, along with a whole bunch of Exar 8250 fixes. These are ACKed by Greg and also hit drivers/platform/* where they are ACKed by Andy Shevchenko. Speaking about drivers/platform/* there is also a bunch of ACPI stuff coming through that route, again ACKed by Andy. The MCP23S08 changes are coming in here as well. You already have the commits in your tree, so this is just a result of sharing an immutable branch between pin control and GPIO. Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage.

2017-07-06mm, memory_hotplug: drop CONFIG_MOVABLE_NODEMichal Hocko1-2/+5
Commit 20b2f52b73fe ("numa: add CONFIG_MOVABLE_NODE for movable-dedicated node") has introduced CONFIG_MOVABLE_NODE without a good explanation on why it is actually useful. It makes a lot of sense to make movable node semantic opt in but we already have that because the feature has to be explicitly enabled on the kernel command line. A config option on top only makes the configuration space larger without a good reason. It also adds an additional ifdefery that pollutes the code. Just drop the config option and make it de-facto always enabled. This shouldn't introduce any change to the semantic.

2017-07-06mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objectsCatalin Marinas1-0/+1
Kmemleak requires that vmalloc'ed objects have a minimum reference count of 2: one in the corresponding vm_struct object and the other owned by the vmalloc() caller. There are cases, however, where the original vmalloc() returned pointer is lost and, instead, a pointer to vm_struct is stored (see free_thread_stack()). Kmemleak currently reports such objects as leaks. This patch adds support for treating any surplus references to an object as additional references to a specified object. It introduces the kmemleak_vmalloc() API function which takes a vm_struct pointer and sets its surplus reference passing to the actual vmalloc() returned pointer. The __vmalloc_node_range() calling site has been modified accordingly.

2017-07-06ksm: introduce ksm_max_page_sharing per page deduplication limitAndrea Arcangeli1-0/+63
Without a max deduplication limit for each KSM page, the list of the rmap_items associated to each stable_node can grow infinitely large. During the rmap walk each entry can take up to ~10usec to process because of IPIs for the TLB flushing (both for the primary MMU and the secondary MMUs with the MMU notifier). With only 16GB of address space shared in the same KSM page, that would amount to dozens of seconds of kernel runtime. A ~256 max deduplication factor will reduce the latencies of the rmap walks on KSM pages to order of a few msec. Just doing the cond_resched() during the rmap walks is not enough, the list size must have a limit too, otherwise the caller could get blocked in (schedule friendly) kernel computations for seconds, unexpectedly. There's room for optimization to significantly reduce the IPI delivery cost during the page_referenced(), but at least for page_migration in the KSM case (used by hard NUMA bindings, compaction and NUMA balancing) it may be inevitable to send lots of IPIs if each rmap_item->mm is active on a different CPU and there are lots of CPUs. Even if we ignore the IPI delivery cost, we've still to walk the whole KSM rmap list, so we can't allow millions or billions (ulimited) number of entries in the KSM stable_node rmap_item lists. The limit is enforced efficiently by adding a second dimension to the stable rbtree. So there are three types of stable_nodes: the regular ones (identical as before, living in the first flat dimension of the stable rbtree), the "chains" and the "dups". Every "chain" and all "dups" linked into a "chain" enforce the invariant that they represent the same write protected memory content, even if each "dup" will be pointed by a different KSM page copy of that content. This way the stable rbtree lookup computational complexity is unaffected if compared to an unlimited max_sharing_limit. It is still enforced that there cannot be KSM page content duplicates in the stable rbtree itself. Adding the second dimension to the stable rbtree only after the max_page_sharing limit hits, provides for a zero memory footprint increase on 64bit archs. The memory overhead of the per-KSM page stable_tree and per virtual mapping rmap_item is unchanged. Only after the max_page_sharing limit hits, we need to allocate a stable_tree "chain" and rb_replace() the "regular" stable_node with the newly allocated stable_node "chain". After that we simply add the "regular" stable_node to the chain as a stable_node "dup" by linking hlist_dup in the stable_node_chain->hlist. This way the "regular" (flat) stable_node is converted to a stable_node "dup" living in the second dimension of the stable rbtree. During stable rbtree lookups the stable_node "chain" is identified as stable_node->rmap_hlist_len == STABLE_NODE_CHAIN (aka is_stable_node_chain()). When dropping stable_nodes, the stable_node "dup" is identified as stable_node->head == STABLE_NODE_DUP_HEAD (aka is_stable_node_dup()). The STABLE_NODE_DUP_HEAD must be an unique valid pointer never used elsewhere in any stable_node->head/node to avoid a clashes with the stable_node->node.rb_parent_color pointer, and different from &migrate_nodes. So the second field of &migrate_nodes is picked and verified as always safe with a BUILD_BUG_ON in case the list_head implementation changes in the future. The STABLE_NODE_DUP is picked as a random negative value in stable_node->rmap_hlist_len. rmap_hlist_len cannot become negative when it's a "regular" stable_node or a stable_node "dup". The stable_node_chain->nid is irrelevant. The stable_node_chain->kpfn is aliased in a union with a time field used to rate limit the stable_node_chain->hlist prunes. The garbage collection of the stable_node_chain happens lazily during stable rbtree lookups (as for all other kind of stable_nodes), or while disabling KSM with "echo 2 >/sys/kernel/mm/ksm/run" while collecting the entire stable rbtree. While the "regular" stable_nodes and the stable_node "dups" must wait for their underlying tree_page to be freed before they can be freed themselves, the stable_node "chains" can be freed immediately if the stable_node->hlist turns empty. This is because the "chains" are never pointed by any page->mapping and they're effectively stable rbtree KSM self contained metadata.

2017-07-06mm: allow slab_nomerge to be set at build timeKees Cook1-2/+8
Some hardened environments want to build kernels with slab_nomerge already set (so that they do not depend on remembering to set the kernel command line option). This is desired to reduce the risk of kernel heap overflows being able to overwrite objects from merged caches and changes the requirements for cache layout control, increasing the difficulty of these attacks. By keeping caches unmerged, these kinds of exploits can usually only damage objects in the same cache (though the risk to metadata exploitation is unchanged).

Pull security layer updates from James Morris: - a major update for AppArmor. From JJ: * several bug fixes and cleanups * the patch to add symlink support to securityfs that was floated on the list earlier and the apparmorfs changes that make use of securityfs symlinks * it introduces the domain labeling base code that Ubuntu has been carrying for several years, with several cleanups applied. And it converts the current mediation over to using the domain labeling base, which brings domain stacking support with it. This finally will bring the base upstream code in line with Ubuntu and provide a base to upstream the new feature work that Ubuntu carries. * This does _not_ contain any of the newer apparmor mediation features/controls (mount, signals, network, keys, ...) that Ubuntu is currently carrying, all of which will be RFC'd on top of this. - Notable also is the Infiniband work in SELinux, and the new file:map permission.

Almost all of these changes are the SELinux/IB work done by Daniel Jurgens; some other noteworthy changes include a NFS v4.2 labeling fix, a new file:map permission, and reporting of policy capabilities on policy load" There's also now genfscon labeling support for tracefs, which was lost in v4.1 with the separation from debugfs. - Smack incorporates a safer socket check in file_receive, and adds a cap_capable call in privilege check. - TPM as usual has a bunch of fixes and enhancements. - Multiple calls to security_add_hooks() can now be made for the same LSM, to allow LSMs to have hook declarations across multiple files. - IMA now supports different "ima_appraise=" modes (eg. log, fix) from the boot command line. * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (126 commits) apparmor: put back designators in struct initialisers seccomp: Switch from atomic_t to recount_t seccomp: Adjust selftests to avoid double-join seccomp: Clean up core dump logic IMA: update IMA policy documentation to include pcr= option ima: Log the same audit cause whenever a file has no signature ima: Simplify policy_func_show. integrity: Small code improvements ima: fix get_binary_runtime_size() ima: use ima_parse_buf() to parse template data ima: use ima_parse_buf() to parse measurements headers ima: introduce ima_parse_buf() ima: Add cgroups2 to the defaults list ima: use memdup_user_nul ima: fix up #endif comments IMA: Correct Kconfig dependencies for hash selection ima: define is_ima_appraise_enabled() ima: define Kconfig IMA_APPRAISE_BOOTPARAM option ima: define a set of appraisal rules requiring file signatures ima: extend the "ima_policy" boot command line to support multiple policies ...
2017-07-05dt-bindings: phy: dp83867: provide a workaround for incorrect RX_CTRL pin strapMurali Karicheri1-0/+7
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). It further advises that if a board has this pin strapped in mode 1 and mode 2, then to ensure proper operation of the PHY, a software workaround must be implemented. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property for the board to advertise this and allow corrective action in software.

Pull ARM 64-bit DT updates from Arnd Bergmann: "Device-tree updates for arm64 platforms. For the first time I can remember, this is actually larger than the corresponding branch for 32-bit platforms overall, though that has more individual changes. A significant portion this time is due to added machine support: - Initial support for the Realtek RTD1295 SoC, along with the Zidoo X9S set-top-box - Initial support for Actions Semi S900 and the Bubblegum-96 single-board-cёmputer. - Rockchips support for the rk3399-Firefly single-board-computer gets added, this one stands out for being relatively fast, affordable and well₋supported, compared to many boards that only fall into one or two of the above categories. - Mediatek gains support for the mt6797 mobile-phone SoC platform and corresponding evaluation board. - Amlogic board support gets added for the NanoPi K2 and S905x LibreTech CC single-board computers and the R-Box Pro set-top-box - Allwinner board support gets added for the OrangePi Win, Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers and the SoPine system-on-module. - Renesas board support for Salvator-XS and H3ULCB automotive development systems. - Socionext Uniphier board support for LD11-global and LD20-global, whatever those may be. - Broadcom adds support for the new Stingray communication processor in its iProc family, along with two reference boards. Other updates include: - For the hisicon platform, support for Hi3660-Hikey960 gets extended significantly. - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier, Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (243 commits) ARM64: dts: marvell: armada37xx: Fix timer interrupt specifiers Revert "arm64: dts: marvell: add dma-mask in crypto nodes for 7k/8k" arm64: dts: mediatek: don't include missing file ARM64: dts: meson-gxl: Add Libre Technology CC support dt-bindings: arm: amlogic: Add Libre Technology CC board dt-bindings: add Libre Technology vendor prefix arm64: dts: marvell: enable GICP and ICU on Armada 7K/8K arm64: dts: zte: Use - instead of @ for DT OPP entries arm64: dts: marvell: add gpio support for Armada 7K/8K arm64: dts: marvell: add pinctrl support for Armada 7K/8K arm64: dts: marvell: use new binding for the system controller on cp110 arm64: dts: marvell: remove *-clock-output-names on cp110 arm64: dts: marvell: use new bindings for xor clocks on ap806 arm64: dts: marvell: mcbin: enable the mdio node arm64: dts: Add Actions Semi S900 and Bubblegum-96 dt-bindings: Add vendor prefix for uCRobotics arm64: dts: marvell: add xmdio nodes for 7k/8k arm64: dts: marvell: add a comment on the cp110 slave node status arm64: dts: marvell: remove cpm crypto nodes from dts files arm64: dts: marvell: cp110: enable the crypto engine at the SoC level ...
