git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - DM core passthrough ioctl fix to retain reference to DM table, and that table's block devices, while issuing the ioctl to one of those block devices. - DM core passthrough ioctl fix to _not_ override the fmode_t used to issue the ioctl. Overriding by using the fmode_t that the block device was originally open with during DM table load is a liability. - Add DM core support for secure erase forwarding and update the DM linear and DM striped targets to support them. - A DM core 4.16 stable fix to allow abnormal IO (e.g. discard, write same, write zeroes) for targets that make use of the non-splitting IO variant (as is done for multipath or thinp when layered directly on NVMe). - Allow DM targets to return a payload in response to a DM message that they are sent. This is useful for DM targets that would like to provide statistics data in response to DM messages. - Update DM bufio to support non-power-of-2 block sizes. Numerous other related changes prepare the DM bufio code for this support. - Fix DM crypt to use a bounded amount of memory across the entire system. This is to avoid OOM that can otherwise occur in response to certain pathological IO workloads (e.g. discarding a large DM crypt device). - Add a 'check_at_most_once' feature to the DM verity target to allow verity to be used on mobile devices that have very limited resources. - Fix the DM integrity target to fail early if a keyed algorithm (e.g. HMAC) is to be used but the key isn't set. - Add non-power-of-2 support to the DM unstripe target. - Eliminate the use of a Variable Length Array in the DM stripe target. - Update the DM log-writes target to record metadata (REQ_META flag). - DM raid fixes for its nosync status and some variable range issues. * tag 'for-4.17/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (28 commits) dm: remove fmode_t argument from .prepare_ioctl hook dm: hold DM table for duration of ioctl rather than use blkdev_get dm raid: fix parse_raid_params() variable range issue dm verity: make verity_for_io_block static dm verity: add 'check_at_most_once' option to only validate hashes once dm bufio: don't embed a bio in the dm_buffer structure dm bufio: support non-power-of-two block sizes dm bufio: use slab cache for dm_buffer structure allocations dm bufio: reorder fields in dm_buffer structure dm bufio: relax alignment constraint on slab cache dm bufio: remove code that merges slab caches dm bufio: get rid of slab cache name allocations dm bufio: move dm-bufio.h to include/linux/ dm bufio: delete outdated comment dm: add support for secure erase forwarding dm: backfill abnormal IO support to non-splitting IO submission dm raid: fix nosync status dm mpath: use DM_MAPIO_SUBMITTED instead of magic number 0 in process_queued_bios() dm stripe: get rid of a Variable Length Array (VLA) dm log writes: record metadata flag for better flags record ...

2018-04-06cpuidle: Return nohz hint from cpuidle_select()Rafael J. Wysocki
Add a new pointer argument to cpuidle_select() and to the ->select cpuidle governor callback to allow a boolean value indicating whether or not the tick should be stopped before entering the selected state to be returned from there. Make the ladder governor ignore that pointer (to preserve its current behavior) and make the menu governor return 'false" through it if: (1) the idle exit latency is constrained at 0, or (2) the selected state is a polling one, or (3) the expected idle period duration is within the tick period range. In addition to that, the correction factor computations in the menu governor need to take the possibility that the tick may not be stopped into account to avoid artificially small correction factor values. To that end, add a mechanism to record tick wakeups, as suggested by Peter Zijlstra, and use it to modify the menu_update() behavior when tick wakeup occurs. Namely, if the CPU is woken up by the tick and the return value of tick_nohz_get_sleep_length() is not within the tick boundary, the predicted idle duration is likely too short, so make menu_update() try to compensate for that by updating the governor statistics as though the CPU was idle for a long time. Since the value returned through the new argument pointer of cpuidle_select() is not used by its caller yet, this change by itself is not expected to alter the functionality of the code.

Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious reason.

This results in lower memory consumption: - zsmalloc now uses 47424 physical pages, which is less than 48787 pages zsmalloc used before. - objects that we store in class-3264 share zspages. That's why overall the number of pages that both class-4096 and class-3264 consumed went down from 10924 to 9564.

2018-04-05mm/memory_hotplug: optimize memory hotplugPavel Tatashin
During memory hotplugging we traverse struct pages three times: 1. memset(0) in sparse_add_one_section() 2. loop in __add_section() to set do: set_page_node(page, nid); and SetPageReserved(page); 3. loop in memmap_init_zone() to call __init_single_pfn() This patch removes the first two loops, and leaves only loop 3. All struct pages are initialized in one place, the same as it is done during boot. The benefits: - We improve memory hotplug performance because we are not evicting the cache several times and also reduce loop branching overhead. - Remove condition from hotpath in __init_single_pfn(), that was added in order to fix the problem that was reported by Bharata in the above email thread, thus also improve performance during normal boot. - Make memory hotplug more similar to the boot memory initialization path because we zero and initialize struct pages only in one function. - Simplifies memory hotplug struct page initialization code, and thus enables future improvements, such as multi-threading the initialization of struct pages in order to improve hotplug performance even further on larger machines.

2018-04-05mm/memory_hotplug: don't read nid from struct page during hotplugPavel Tatashin
During memory hotplugging the probe routine will leave struct pages uninitialized, the same as it is currently done during boot. Therefore, we do not want to access the inside of struct pages before __init_single_page() is called during onlining. Because during hotplug we know that pages in one memory block belong to the same numa node, we can skip the checking. We should keep checking for the boot case.

2018-04-05mm/memory_hotplug: optimize probe routinePavel Tatashin
When memory is hotplugged pages_correctly_reserved() is called to verify that the added memory is present, this routine traverses through every struct page and verifies that PageReserved() is set. This is a slow operation especially if a large amount of memory is added. Instead of checking every page, it is enough to simply check that the section is present, has mapping (struct page array is allocated), and the mapping is online. In addition, we should not excpect that probe routine sets flags in struct page, as the struct pages have not yet been initialized. The initialization should be done in __init_single_page(), the same as during boot.

In preparation for re-working the ARS implementation to better handle short vs long ARS runs, introduce nfit_spa->ars_state.

2018-04-05hv_netvsc: Pass net_device parameter to revoke and teardown functionsMohammed Gamal
The callers to netvsc_revoke_*_buf() and netvsc_teardown_*_gpadl() already have their net_device instances. Pass them as a paramaeter to the function instead of obtaining them from netvsc_device struct everytime Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Signed-off-by: David S.

2018-04-05hv_netvsc: Ensure correct teardown message sequence orderMohammed Gamal
Prior to commit 0cf737808ae7 ("hv_netvsc: netvsc_teardown_gpadl() split") the call sequence in netvsc_device_remove() was as follows (as implemented in netvsc_destroy_buf()): 1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message 2- Teardown receive buffer GPADL 3- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message 4- Teardown send buffer GPADL 5- Close vmbus This didn't work for WS2016 hosts. Commit 0cf737808ae7 ("hv_netvsc: netvsc_teardown_gpadl() split") rearranged the teardown sequence as follows: 1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message 2- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message 3- Close vmbus 4- Teardown receive buffer GPADL 5- Teardown send buffer GPADL That worked well for WS2016 hosts, but it prevented guests on older hosts from shutting down after changing network settings. Commit 0ef58b0a05c1 ("hv_netvsc: change GPAD teardown order on older versions") ensured the following message sequence for older hosts 1- Send NVSP_MSG1_TYPE_REVOKE_RECV_BUF message 2- Send NVSP_MSG1_TYPE_REVOKE_SEND_BUF message 3- Teardown receive buffer GPADL 4- Teardown send buffer GPADL 5- Close vmbus However, with this sequence calling `ip link set eth0 mtu 1000` hangs and the process becomes uninterruptible. On futher analysis it turns out that on tearing down the receive buffer GPADL the kernel is waiting indefinitely in vmbus_teardown_gpadl() for a completion to be signaled. Here is a snippet of where this occurs: int vmbus_teardown_gpadl(struct vmbus_channel *channel, u32 gpadl_handle) { struct vmbus_channel_gpadl_teardown *msg; struct vmbus_channel_msginfo *info; unsigned long flags; int ret; info = kmalloc(sizeof(*info) + sizeof(struct vmbus_channel_gpadl_teardown), GFP_KERNEL); if (!info) return -ENOMEM; init_completion(&info->waitevent); info->waiting_channel = channel; [....] ret = vmbus_post_msg(msg, sizeof(struct vmbus_channel_gpadl_teardown), true); if (ret) goto post_msg_err; wait_for_completion(&info->waitevent); [....] } The completion is signaled from vmbus_ongpadl_torndown(), which gets called when the corresponding message is received from the host, which apparently never happens in that case. This patch works around the issue by restoring the first mentioned message sequence for older hosts Fixes: 0ef58b0a05c1 ("hv_netvsc: change GPAD teardown order on older versions") Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Signed-off-by: David S.

2018-04-05hv_netvsc: Split netvsc_revoke_buf() and netvsc_teardown_gpadl()Mohammed Gamal
Split each of the functions into two for each of send/recv buffers. This will be needed in order to implement a fine-grained messaging sequence to the host so that we accommodate the requirements of different Windows versions Fixes: 0ef58b0a05c12 ("hv_netvsc: change GPAD teardown order on older versions") Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Signed-off-by: David S.

2018-04-05hv_netvsc: Use Windows version instead of NVSP version on GPAD teardownMohammed Gamal
When changing network interface settings, Windows guests older than WS2016 can no longer shutdown. This was addressed by commit 0ef58b0a05c12 ("hv_netvsc: change GPAD teardown order on older versions"), however the issue also occurs on WS2012 guests that share NVSP protocol versions with WS2016 guests. Hence we use Windows version directly to differentiate them.
