2022-06-29nvme-tcp: always fail a request when sending it failedSagi Grimberg
queue stoppage and inflight requests cancellation is fully fenced from io_work and thus failing a request from this context. Hence we don't need to try to guess from the socket retcode if this failure is because the queue is about to be torn down or not. We are perfectly safe to just fail it, the request will not be cancelled later on.

2022-06-29nvmet-tcp: fix regression in data_digest calculationSagi Grimberg
Data digest calculation iterates over command mapped iovec. However since commit bac04454ef9f we unmap the iovec before we handle the data digest, and since commit 69b85e1f1d1d we clear nr_mapped when we unmap the iov. Instead of open-coding the command iov traversal, simply call crypto_ahash_digest with the command sg that is already allocated (we already do that for the send path). Rename nvmet_tcp_send_ddgst to nvmet_tcp_calc_ddgst and call it from send and recv paths.

2022-06-21block: pop cached rq before potentially blocking rq_qos_throttle()Jens Axboe
If rq_qos_throttle() ends up blocking, then we will have invalidated and flushed our current plug. Since blk_mq_get_cached_request() hasn't popped the cached request off the plug list just yet, we end holding a pointer to a request that is no longer valid. This insta-crashes with rq->mq_hctx being NULL in the validity checks just after. Pop the request off the cached list before doing rq_qos_throttle() to avoid using a potentially stale request.

2022-06-17block: remove per-disk debugfs files in blk_unregister_queueChristoph Hellwig
The block debugfs files are created in blk_register_queue, which is called by add_disk and use a naming scheme based on the disk_name. After del_gendisk returns that name can be reused and thus we must not leave these debugfs files around, otherwise the kernel is unhappy and spews messages like: Directory XXXXX with parent 'block' already present! and the newly created devices will not have working debugfs files. Move the unregistration to blk_unregister_queue instead (which matches the sysfs unregistration) to make sure the debugfs life time rules match those of the disk name. As part of the move also make sure the whole debugfs unregistration is inside a single debugfs_mutex critical section. Note that this breaks blktests block/002, which checks that the debugfs directory has not been removed while blktests is running, but that particular check should simply be removed from the test case.

Use the existing debugfs_mutex to serialize all debugfs operations that rely on q->debugfs_dir or the directories hanging off it. To make the teardown code a little simpler declare all debugfs dentry pointers and not just the main one uncoditionally in blkdev.h. Move debugfs_mutex next to the dentries that it protects and document what it is used for.

2022-06-17block: disable the elevator int del_gendiskChristoph Hellwig
The elevator is only used for file system requests, which are stopped in del_gendisk. Move disabling the elevator and freeing the scheduler tags to the end of del_gendisk instead of doing that work in disk_release and blk_cleanup_queue to avoid a use after free on q->tag_set from disk_release as the tag_set might not be alive at that point. Move the blk_qos_exit call as well, as it just depends on the elevator exit and would be the only reason to keep the not exactly cheap queue freeze in disk_release.

2022-06-13nvme-pci: avoid the deepest sleep state on ZHITAI TiPro7000 SSDsNing Wang
When ZHITAI TiPro7000 SSDs entered deepest power state(ps4) it has the same APST sleep problem as Kingston A2000. by chance the system crashes and displays the same dmesg info: https://bugzilla.kernel.org/show_bug.cgi?id=195039#c65 As the Archlinux wiki suggest (enlat + exlat) < 25000 is fine and my testing shows no system crashes ever since. Therefore disabling the deepest power state will fix the APST sleep issue. https://wiki.archlinux.org/title/Solid_state_drive/NVMe This is the APST data from 'nvme id-ctrl /dev/nvme1' NVME Identify Controller: vid : 0x1e49 ssvid : 0x1e49 sn : [...] mn : ZHITAI TiPro7000 1TB fr : ZTA32F3Y [...] ps 0 : mp:3.50W operational enlat:5 exlat:5 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps 1 : mp:3.30W operational enlat:50 exlat:100 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps 2 : mp:2.80W operational enlat:50 exlat:200 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps 3 : mp:0.1500W non-operational enlat:500 exlat:5000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- ps 4 : mp:0.0200W non-operational enlat:2000 exlat:60000 rrt:4 rrl:4 rwt:4 rwl:4 idle_power:- active_power:- Signed-off-by: Ning Wang <ningwang35@outlook.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

2022-06-12platform/x86: hp-wmi: Resolve WMI query failures on some devicesJorge Lopez
WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.
