2017-11-13RDMA/core: Rename kernel modify_cq to better describe its usageLeon Romanovsky
Current ib_modify_cq() is used to set CQ moderation parameters. This patch renames ib_modify_cq() to be rdma_set_cq_moderation(), because the kernel version of RDMA API doesn't need to follow already exposed to user's API pattern (create_XXX/modify_XXX/query_XXX/destroy_XXX) and better to have more accurate name which describes the actual usage.

2017-11-13IB/uverbs: Add CQ moderation capability to query_deviceYonatan Cohen
The query_device function can now obtain the maximum values for cq_max_count and cq_period, needed for CQ moderation. cq_max_count is a 16 bits number that determines the number of CQEs to accumulate before generating an event. cq_period is a 16 bits number that determines the timeout in micro seconds from the last event generated, upon which a new event will be generated even if cq_max_count was not reached.

2017-11-13IB/uverbs: Allow CQ moderation with modify CQYonatan Cohen
Uverbs support in modify_cq for CQ moderation only. Gives ability to change cq_max_count and cq_period. CQ moderation enhance performance by moderating the number of CQEs needed to create an event instead of application having to suffer from event per-CQE. To achieve CQ moderation the application needs to set cq_max_count and cq_period. cq_max_count - defines the number of CQEs needed to create an event. cq_period - defines the timeout (micro seconds) between last event and a new one that will occur even if cq_max_count was not satisfied Signed-off-by: Yonatan Cohen <yonatanc@mellanox.com> Reviewed-by: Majd Dibbiny <majd@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>

2017-11-10IB/core: Add PCI write end padding flags for WQ and QPNoa Osherovich
There are root complexes that are able to optimize their performance when incoming data is multiple full cache lines. PCI write end padding is the device's ability to pad the ending of incoming packets (scatter) to full cache line such that the last upstream write generated by an incoming packet will be a full cache line. Add a relevant entry to ib_device_cap_flags to report such capability of an RDMA device. Add the QP and WQ create flags: * A QP/WQ created with a scatter end padding flag will cause HW to pad the last upstream write generated by a packet to cache line. User should consider several factors before activating this feature: - In case of high CPU memory load (which may cause PCI back pressure in turn), if a large percent of the writes are partial cache line, this feature should be checked as an optional solution. - This feature might reduce performance if most packets are between one and two cache lines and PCIe throughput has reached its maximum capacity. E.g. 65B packet from the network port will lead to 128B write on PCIe, which may cause traffic on PCIe to reach high throughput.

2017-11-10RDMA/umem: Avoid partial declaration of non-static functionLeon Romanovsky
The RDMA/umem uses generic RB-trees macros to generate various ib_umem access functions. The generation is performed with INTERVAL_TREE_DEFINE macro, which allows one of two modes: declare all functions as static or declare none of the function to be static. The second mode of operation produces the following sparse errors: drivers/infiniband/core/umem_rbtree.c:69:1: warning: symbol 'rbt_ib_umem_iter_first' was not declared. Should it be static? drivers/infiniband/core/umem_rbtree.c:69:1: warning: symbol 'rbt_ib_umem_iter_next' was not declared. Should it be static? Code relocation together with declaration of such functions to be "static" solves the issue. Because there is no need to have separate file for two functions, let's consolidate umem_rtree.c and umem_odp.c into one file.

This was incorrect, as the largest possible header size is the largest possible combination of headers we might run into. The new code accounts for all possible headers in the largest possible combination and subtracts that from the MTU to make sure that all packets will fit on the wire.

2017-10-18IB/core: Introduce and use rdma_create_user_ahParav Pandit
Introduce rdma_create_user_ah API which allows passing udata to provider driver and additionally which resolves DMAC for RoCE. ib_resolve_eth_dmac() resolves destination mac address for unicast, multicast, link local ipv4 mapped ipv6 and ipv6 destination gid entry. This allows all RoCE provider drivers to avoid duplicating such code. Such change brings consistency where IB core always resolves dmac and pass it to RoCE provider drivers for user and kernel consumers, with this ah_attr->roce.dmac is always an input field for provider drivers. This uniformity avoids exporting ib_resolve_eth_dmac symbol to providers or other modules. Therefore its removed as exported symbol at later in the patch series. Now uverbs and umad both makes use of rdma_create_user_ah API which fixes the issue where umad has invalid DMAC for address.

The patch series addresses this by removing all duct tape and refactoring it into a workable state. The reasons why I ask for inclusion that late in the cycle are: 1) The code causes lockdep splats vs. hotplug locking which get reported over and over. Unfortunately there is no easy fix. 2) The risk of breakage is minimal because it's already broken 3) As 4.14 is a long term stable kernel, I prefer to have working watchdog code in that and the lockdep issues resolved. I wouldn't ask you to pull if 4.14 wouldn't be a LTS kernel or if the solution would be easy to backport. 4) The series was around before the merge window opened, but then got delayed due to the UP failure caused by the for_each_cpu() surprise which we discussed recently. Changes vs. V1: - Addressed your review points - Addressed the warning in the powerpc code which was discovered late - Changed two function names which made sense up to a certain point in the series.

2017-10-04powerpc/watchdog: Make use of watchdog_nmi_probe()Thomas Gleixner
The rework of the core hotplug code triggers the WARN_ON in start_wd_cpu() on powerpc because it is called multiple times for the boot CPU. The first call is via: start_wd_on_cpu+0x80/0x2f0 watchdog_nmi_reconfigure+0x124/0x170 softlockup_reconfigure_threads+0x110/0x130 lockup_detector_init+0xbc/0xe0 kernel_init_freeable+0x18c/0x37c kernel_init+0x2c/0x160 ret_from_kernel_thread+0x5c/0xbc And then again via the CPU hotplug registration: start_wd_on_cpu+0x80/0x2f0 cpuhp_invoke_callback+0x194/0x620 cpuhp_thread_fun+0x7c/0x1b0 smpboot_thread_fn+0x290/0x2a0 kthread+0x168/0x1b0 ret_from_kernel_thread+0x5c/0xbc This can be avoided by setting up the cpu hotplug state with nocalls and move the initialization to the watchdog_nmi_probe() function. That initializes the hotplug callbacks without invoking the callback and the following core initialization function then configures the watchdog for the online CPUs (in this case CPU0) via softlockup_reconfigure_threads().

2017-10-04watchdog/core, powerpc: Replace watchdog_nmi_reconfigure()Thomas Gleixner
The recent cleanup of the watchdog code split watchdog_nmi_reconfigure() into two stages. One to stop the NMI and one to restart it after reconfiguration. That was done by adding a boolean 'run' argument to the code, which is functionally correct but not necessarily a piece of art. Replace it by two explicit functions: watchdog_nmi_stop() and watchdog_nmi_start().

2017-10-04mmc: Delete bounce buffer handlingLinus Walleij
In may, Steven sent a patch deleting the bounce buffer handling and the CONFIG_MMC_BLOCK_BOUNCE option. I chose the less invasive path of making it a runtime config option, and we merged that successfully for kernel v4.12. The code is however just standing in the way and taking up space for seemingly no gain on any systems in wide use today. Pierre says the code was there to improve speed on TI SDHCI controllers on certain HP laptops and possibly some Ricoh controllers as well. Early SDHCI controllers lacked the scatter-gather feature, which made software bounce buffers a significant speed boost. We are clearly talking about the list of SDHCI PCI-based MMC/SD card readers found in the pci_ids[] list in drivers/mmc/host/sdhci-pci-core.c. The TI SDHCI derivative is not supported by the upstream kernel. This leaves the Ricoh. What we can however notice is that the x86 defconfigs in the kernel did not enable CONFIG_MMC_BLOCK_BOUNCE option, which means that any such laptop would have to have a custom configured kernel to actually take advantage of this bounce buffer speed-up. It simply seems like there was a speed optimization for the Ricoh controllers that noone was using. (I have not checked the distro defconfigs but I am pretty sure the situation is the same there.) Bounce buffers increased performance on the OMAP HSMMC at one point, and was part of the original submission in commit a45c6cb81647 ("[ARM] 5369/1: omap mmc: Add new omap hsmmc controller for 2430 and 34xx, v3") This optimization was removed in commit 0ccd76d4c236 ("omap_hsmmc: Implement scatter-gather emulation") which found that scatter-gather emulation provided even better performance. The same was introduced for SDHCI in commit 2134a922c6e7 ("sdhci: scatter-gather (ADMA) support") I am pretty positively convinced that software scatter-gather emulation will do for any host controller what the bounce buffers were doing. Essentially, the bounce buffer was a reimplementation of software scatter-gather-emulation in the MMC subsystem, and it should be done away with.

2017-10-03mm/memory_hotplug: change pfn_to_section_nr/section_nr_to_pfn macro to ↵YASUAKI ISHIMATSU
inline function pfn_to_section_nr() and section_nr_to_pfn() are defined as macro. pfn_to_section_nr() has no issue even if it is defined as macro. But section_nr_to_pfn() has overflow issue if sec is defined as int. section_nr_to_pfn() just shifts sec by PFN_SECTION_SHIFT. If sec is defined as unsigned long, section_nr_to_pfn() returns pfn as 64 bit value. But if sec is defined as int, section_nr_to_pfn() returns pfn as 32 bit value. __remove_section() calculates start_pfn using section_nr_to_pfn() and scn_nr defined as int. So if hot-removed memory address is over 16TB, overflow issue occurs and section_nr_to_pfn() does not calculate correct pfn. To make callers use proper arg, the patch changes the macros to inline functions.

Patch series "exec: binfmt_misc: fix use-after-free, kill iname[BINPRM_BUF_SIZE]". It looks like this code was always wrong, then commit 948b701a607f ("binfmt_misc: add persistent opened binary handler for containers") added more problems. This patch (of 6): load_script() can simply use i_name instead, it points into bprm->buf[] and nobody can change this memory until we call prepare_binprm(). The only complication is that we need to also change the signature of bprm_change_interp() but this change looks good too. While at it, do whitespace/style cleanups. NOTE: the real motivation for this change is that people want to increase BINPRM_BUF_SIZE, we need to change load_misc_binary() too but this looks more complicated because afaics it is very buggy.

2017-10-03mm, oom_reaper: skip mm structs with mmu notifiersMichal Hocko
Andrea has noticed that the oom_reaper doesn't invalidate the range via mmu notifiers (mmu_notifier_invalidate_range_start/end) and that can corrupt the memory of the kvm guest for example. tlb_flush_mmu_tlbonly already invokes mmu notifiers but that is not sufficient as per Andrea: "mmu_notifier_invalidate_range cannot be used in replacement of mmu_notifier_invalidate_range_start/end. For KVM mmu_notifier_invalidate_range is a noop and rightfully so. A MMU notifier implementation has to implement either ->invalidate_range method or the invalidate_range_start/end methods, not both. And if you implement invalidate_range_start/end like KVM is forced to do, calling mmu_notifier_invalidate_range in common code is a noop for KVM. For those MMU notifiers that can get away only implementing ->invalidate_range, the ->invalidate_range is implicitly called by mmu_notifier_invalidate_range_end(). And only those secondary MMUs that share the same pagetable with the primary MMU (like AMD iommuv2) can get away only implementing ->invalidate_range" As the callback is allowed to sleep and the implementation is out of hand of the MM it is safer to simply bail out if there is an mmu notifier registered. In order to not fail too early make the mm_has_notifiers check under the oom_lock and have a little nap before failing to give the current oom victim some more time to exit.
