[PATCH 6.6.y] kselftest: Add a ksft_perror() helper

by Edward Liaw

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 907f33028871fa7c9a3db1efd467b78ef82cce20 ] The standard library perror() function provides a convenient way to print an error message based on the current errno but this doesn't play nicely with KTAP output. Provide a helper which does an equivalent thing in a KTAP compatible format. nolibc doesn't have a strerror() and adding the table of strings required doesn't seem like a good fit for what it's trying to do so when we're using that only print the errno.

In __update_and_free_hugetlb_folio(), folio->_deferred_list is initialized leading to corrupted folio->_hugetlb_subpool when folio is hugetlb. Later free_huge_folio() will use _hugetlb_subpool and above warning happens. But it is assumed hugetlb flag must have been cleared when calling folio_put() in update_and_free_hugetlb_folio(). This assumption is broken due to below race: CPU1 CPU2 dissolve_free_huge_page update_and_free_pages_bulk update_and_free_hugetlb_folio hugetlb_vmemmap_restore_folios folio_clear_hugetlb_vmemmap_optimized clear_flag = folio_test_hugetlb_vmemmap_optimized if (clear_flag) <-- False, it's already cleared. __folio_clear_hugetlb(folio) <-- Hugetlb is not cleared. folio_put free_huge_folio <-- free_the_page is expected. list_for_each_entry() __folio_clear_hugetlb <-- Too late. Fix this issue by checking whether folio is hugetlb directly instead of checking clear_flag to close the race window.

[PATCH] drm/exynos: hdmi: report safe 640x480 mode as a fallback when no EDID found

by Marek Szyprowski

When reading EDID fails and driver reports no modes available, the DRM core adds an artificial 1024x786 mode to the connector. Unfortunately some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not able to drive such mode, so report a safe 640x480 mode instead of nothing in case of the EDID reading failure. This fixes the following issue observed on Trats2 board since commit 13d5b040363c ("drm/exynos: do not return negative values from .get_modes()"): [drm] Exynos DRM: using 11c00000.fimd device for DMA

This was intended to skip the check on the first extent, but in the error image above, prev=0+1-1=0 when checking the second extent, so even though lblock<=prev, the function does not return an error. As a result, bug_ON occurs in __es_tree_search and the system panics. To solve this problem, we only need to check that: 1. The lblock of the first extent is not less than 0. 2. The lblock of the next extent is not less than the next block of the previous extent. The same applies to extent_idx.

[PATCH 1/2] SELinux: Fix lsm_get_self_attr()

selinux_lsm_getattr() may not initialize the value's pointer in some case. As for proc_pid_attr_read(), initialize this pointer to NULL in selinux_getselfattr() to avoid an UAF in the kfree() call.

4.19 stable kernel crash caused by vxlan testing

by zhulei

Hey all, I recently used a testing program to test the 4.19 stable branch kernel and found that a crash occurred immediately. The test source code link is: https://github.com/Backmyheart/src0358/blob/master/vxlan_fdb_destroy.c The test command is as follows: gcc vxlan_fdb_destroy.c -o vxlan_fdb_destroy -lpthread According to its stack, upstream has relevant repair patch, the commit id is 7c31e54aeee517d1318dfc0bde9fa7de75893dc6. May i ask if the 4.19 kernel will port this patch ?

Part of this glue code are the local functions `__init` and `__exit` that are used to initialize/destroy the Rust module. These functions are safe and also visible to the Rust mod in which the `module!` macro is invoked. This means that they can be called by other safe Rust code. But since they contain `unsafe` blocks that rely on only being called at the right time, this is a soundness issue. Wrap these generated functions inside of two private modules, this guarantees that the public functions cannot be called from the outside. Make the safe functions `unsafe` and add SAFETY comments.

[PATCH 2/2] x86/sgx: Resolve EREMOVE page vs EAUG page data race

by Dmitrii Kuvaiskii

Two enclave threads may try to add and remove the same enclave page simultaneously (e.g., if the SGX runtime supports both lazy allocation and `MADV_DONTNEED` semantics). Consider this race: 1. T1 performs page removal in sgx_encl_remove_pages() and stops right after removing the page table entry and right before re-acquiring the enclave lock to EREMOVE and xa_erase(&encl->page_array) the page. 2. T2 tries to access the page, and #PF[not_present] is raised. The condition to EAUG in sgx_vma_fault() is not satisfied because the page is still present in encl->page_array, thus the SGX driver assumes that the fault happened because the page was swapped out. The driver continues on a code path that installs a page table entry *without* performing EAUG. 3. The enclave page metadata is in inconsistent state: the PTE is installed but there was no EAUG. Thus, T2 in userspace infinitely receives SIGSEGV on this page (and EACCEPT always fails). Fix this by making sure that T1 (the page-removing thread) always wins this data race. In particular, the page-being-removed is marked as such, and T2 retries until the page is fully removed.

[PATCH 1/2] x86/sgx: Resolve EAUG race where losing thread returns SIGBUS

by Dmitrii Kuvaiskii

Two enclave threads may try to access the same non-present enclave page simultaneously (e.g., if the SGX runtime supports lazy allocation). The threads will end up in sgx_encl_eaug_page(), racing to acquire the enclave lock. The winning thread will perform EAUG, set up the page table entry, and insert the page into encl->page_array. The losing thread will then get -EBUSY on xa_insert(&encl->page_array) and proceed to error handling path. This error handling path contains two bugs: (1) SIGBUS is sent to userspace even though the enclave page is correctly installed by another thread, and (2) sgx_encl_free_epc_page() is called that performs EREMOVE even though the enclave page was never intended to be removed. The first bug is less severe because it impacts only the user space; the second bug is more severe because it also impacts the OS state by ripping the page (added by the winning thread) from the enclave. Fix these two bugs (1) by returning VM_FAULT_NOPAGE to the generic Linux fault handler so that no signal is sent to userspace, and (2) by replacing sgx_encl_free_epc_page() with sgx_free_epc_page() so that no EREMOVE is performed.

[PATCH] init: fix allocated page overlapping with PTR_ERR

by Nam Cao

There is nothing preventing kernel memory allocators from allocating a page that overlaps with PTR_ERR(), except for architecture-specific code that setup memblock. It was discovered that RISCV architecture doesn't setup memblock corectly, leading to a page overlapping with PTR_ERR() being allocated, and subsequently crashing the kernel (link in Close: ) The reported crash has nothing to do with PTR_ERR(): the last page (at address 0xfffff000) being allocated leads to an unexpected arithmetic overflow in ext4; but still, this page shouldn't be allocated in the first place. Because PTR_ERR() is an architecture-independent thing, we shouldn't ask every single architecture to set this up. There may be other architectures beside RISCV that have the same problem. Fix this one and for all by reserving the physical memory page that may be mapped to the last virtual memory page as part of low memory. Unfortunately, this means if there is actual memory at this reserved location, that memory will become inaccessible. However, if this page is not reserved, it can only be accessed as high memory, so this doesn't matter if high memory is not supported. Even if high memory is supported, it is still only one page.

filtering stable patches in lore queries

by Jason A. Donenfeld

Hi, Greg and Sasha add the "X-stable: review" to their patch bombs, with the intention that people will be able to filter these out should they desire to do so. For example, I usually want all threads that match code I care about, but I don't regularly want to see thousand-patch stable series. So this header is helpful. However, I'm not able to formulate a query for lore (to pass to `lei q`) that will match on negating it. The idea would be to exclude the thread if the parent has this header. It looks like public inbox might only index on some headers, but can't generically search all? I'm not sure how it works, but queries only seem to half way work when searching for that header. In the meantime, I've been using this ugly bash script, which gets the job done, but means I have to download everything locally first: #!/bin/bash PWD="${BASH_SOURCE[0]}" PWD="${PWD%/*}" set -e cd "$PWD" echo "[+] Syncing new mail" >&2 lei up "$PWD" echo "[+] Cleaning up stable patch bombs" >&2 mapfile -d $'\0' -t parents < <(grep -F -x -Z -r -l 'X-stable: review' cur tmp new) { [[ -f stable-message-ids ]] && cat stable-message-ids [[ ${#parents[@]} -gt 0 ]] && sed -n 's/^Message-ID: <$.*$>$/\1/p' "${parents[@]}" } | sort -u > stable-message-ids.new mv stable-message-ids.new stable-message-ids [[ -s stable-message-ids ]] || exit 0 mapfile -d $'\0' -t children < <(grep -F -Z -r -l -f - cur tmp new < stable-message-ids) total=$(( ${#parents[@]} + ${#children[@]} )) [[ $total -gt 0 ]] || exit 0 echo "# rm <...$total messages...>" >&2 rm -f "${parents[@]}" "${children[@]}" This results in something like: zx2c4@thinkpad ~/Projects/lkml $ ./update.bash [+] Syncing new mail # https://lore.kernel.org/all/ limiting ... # /usr/bin/curl -gSf -s -d '' https://lore.kernel.org/all/?x=m&t=1&q=(... [+] Cleaning up stable patch bombs # rm <...24593 messages...> It works, but it'd be nice to not even download these messages in the first place. Since I'm deleting message I don't want, I have to keep track of the message IDs of those deleted messages with the stable header in case replies come in later. That's some book keeping, sheesh! Any thoughts on this workflow? Jason

[PATCH] nvme-pci: Add quirk for broken MSIs

Sandisk SN530 NVMe drives have broken MSIs. On systems without MSI-X support, all commands time out resulting in the following message: nvme nvme0: I/O tag 12 (100c) QID 0 timeout, completion polled These timeouts cause the boot to take an excessively-long time (over 20 minutes) while the initial command queue is flushed. Address this by adding a quirk for drives with buggy MSIs.

Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to backlight BDB data. Commit 700034566d68 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version. backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251).

[PATCH v4] i2c: acpi: Unbind mux adapters before delete

by Hamish Martin

There is an issue with ACPI overlay table removal specifically related to I2C multiplexers. Consider an ACPI SSDT Overlay that defines a PCA9548 I2C mux on an existing I2C bus. When this table is loaded we see the creation of a device for the overall PCA9548 chip and 8 further devices - one i2c_adapter each for the mux channels. These are all bound to their ACPI equivalents via an eventual invocation of acpi_bind_one(). When we unload the SSDT overlay we run into the problem. The ACPI devices are deleted as normal via acpi_device_del_work_fn() and the acpi_device_del_list. However, the following warning and stack trace is output as the deletion does not go smoothly: ------------[ cut here ]------------ kernfs: can not remove 'physical_node', no directory WARNING: CPU: 1 PID: 11 at fs/kernfs/dir.c:1674 kernfs_remove_by_name_ns+0xb9/0xc0 Modules linked in: CPU: 1 PID: 11 Comm: kworker/u128:0 Not tainted 6.8.0-rc6+ #1 Hardware name: congatec AG conga-B7E3/conga-B7E3, BIOS 5.13 05/16/2023 Workqueue: kacpi_hotplug acpi_device_del_work_fn RIP: 0010:kernfs_remove_by_name_ns+0xb9/0xc0 Code: e4 00 48 89 ef e8 07 71 db ff 5b b8 fe ff ff ff 5d 41 5c 41 5d e9 a7 55 e4 00 0f 0b eb a6 48 c7 c7 f0 38 0d 9d e8 97 0a d5 ff <0f> 0b eb dc 0f 1f 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 RSP: 0018:ffff9f864008fb28 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff8ef90a8d4940 RCX: 0000000000000000 RDX: ffff8f000e267d10 RSI: ffff8f000e25c780 RDI: ffff8f000e25c780 RBP: ffff8ef9186f9870 R08: 0000000000013ffb R09: 00000000ffffbfff R10: 00000000ffffbfff R11: ffff8f000e0a0000 R12: ffff9f864008fb50 R13: ffff8ef90c93dd60 R14: ffff8ef9010d0958 R15: ffff8ef9186f98c8 FS: 0000000000000000(0000) GS:ffff8f000e240000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f48f5253a08 CR3: 00000003cb82e000 CR4: 00000000003506f0 Call Trace: <TASK> ? kernfs_remove_by_name_ns+0xb9/0xc0 ? __warn+0x7c/0x130 ? kernfs_remove_by_name_ns+0xb9/0xc0 ? report_bug+0x171/0x1a0 ? handle_bug+0x3c/0x70 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? kernfs_remove_by_name_ns+0xb9/0xc0 ? kernfs_remove_by_name_ns+0xb9/0xc0 acpi_unbind_one+0x108/0x180 device_del+0x18b/0x490 ? srso_return_thunk+0x5/0x5f ? srso_return_thunk+0x5/0x5f device_unregister+0xd/0x30 i2c_del_adapter.part.0+0x1bf/0x250 i2c_mux_del_adapters+0xa1/0xe0 i2c_device_remove+0x1e/0x80 device_release_driver_internal+0x19a/0x200 bus_remove_device+0xbf/0x100 device_del+0x157/0x490 ? __pfx_device_match_fwnode+0x10/0x10 ? srso_return_thunk+0x5/0x5f device_unregister+0xd/0x30 i2c_acpi_notify+0x10f/0x140 notifier_call_chain+0x58/0xd0 blocking_notifier_call_chain+0x3a/0x60 acpi_device_del_work_fn+0x85/0x1d0 process_one_work+0x134/0x2f0 worker_thread+0x2f0/0x410 ? __pfx_worker_thread+0x10/0x10 kthread+0xe3/0x110 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x2f/0x50 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1b/0x30 </TASK> ---[ end trace 0000000000000000 ]--- ... repeated 7 more times, 1 for each channel of the mux ... The issue is that the binding of the ACPI devices to their peer I2C adapters is not correctly cleaned up. Digging deeper into the issue we see that the deletion order is such that the ACPI devices matching the mux channel i2c adapters are deleted first during the SSDT overlay removal. For each of the channels we see a call to i2c_acpi_notify() with ACPI_RECONFIG_DEVICE_REMOVE but, because these devices are not actually i2c_clients, nothing is done for them. Later on, after each of the mux channels has been dealt with, we come to delete the i2c_client representing the PCA9548 device. This is the call stack we see above, whereby the kernel cleans up the i2c_client including destruction of the mux and its channel adapters. At this point we do attempt to unbind from the ACPI peers but those peers no longer exist and so we hit the kernfs errors. The fix is to augment i2c_acpi_notify() to handle i2c_adapters. But, given that the life cycle of the adapters is linked to the i2c_client, instead of deleting the i2c_adapters during the i2c_acpi_notify(), we just trigger unbinding of the ACPI device from the adapter device, and allow the clean up of the adapter to continue in the way it always has.

In __update_and_free_hugetlb_folio(), folio->_deferred_list is initialized leading to corrupted folio->_hugetlb_subpool when folio is hugetlb. Later free_huge_folio() will use _hugetlb_subpool and above warning happens. But it is assumed hugetlb flag must have been cleared when calling folio_put() in update_and_free_hugetlb_folio(). This assumption is broken due to below race: CPU1 CPU2 dissolve_free_huge_page update_and_free_pages_bulk update_and_free_hugetlb_folio hugetlb_vmemmap_restore_folios folio_clear_hugetlb_vmemmap_optimized clear_flag = folio_test_hugetlb_vmemmap_optimized if (clear_flag) <-- False, it's already cleared. __folio_clear_hugetlb(folio) <-- Hugetlb is not cleared. folio_put free_huge_folio <-- free_the_page is expected. list_for_each_entry() __folio_clear_hugetlb <-- Too late. Fix this issue by checking whether folio is hugetlb directly instead of checking clear_flag to close the race window.

[PATCH v3] fs/proc/proc_sysctl.c: always initialize i_uid/i_gid

by Thomas Weißschuh

Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() is not implemented. It missed to also adjust net_ctl_set_ownership() to use the same default values in case the computation of a better value fails.

[PATCH] iio: invensense: fix timestamp glitches when switching frequency

by inv.git-commit＠tdk.com

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol(a)tdk.com> When a sensor is running and there is a FIFO frequency change due to another sensor turned on/off, there are glitches on timestamp. Fix that by using only interrupt timestamp when there is the corresponding sensor data in the FIFO. Delete FIFO period handling and simplify internal functions. Update integration inside inv_mpu6050 and inv_icm42600 drivers.

[PATCH] Bluetooth: qca: generalise device address check

by Johan Hovold

The default device address apparently comes from the NVM configuration file and can differ quite a bit. Store the default address when parsing the configuration file and use it to determine whether the controller has been provisioned with an address. This makes sure that devices without a unique address start as unconfigured unless a valid address has been provided in the devicetree.

[PATCH v3] can: mcp251xfd: fix infinite loop when xmit fails

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> When the mcp251xfd_start_xmit() function fails, the driver stops processing messages, and the interrupt routine does not return, running indefinitely even after killing the running application. Error messages: [ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16 [ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3). ... and repeat forever. The issue can be triggered when multiple devices share the same SPI interface. And there is concurrent access to the bus. The problem occurs because tx_ring->head increments even if mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX package while still expecting a response in mcp251xfd_handle_tefif_one(). This patch resolves the issue by decreasing tx_ring->head if mcp251xfd_start_xmit() fails. With the fix, if we trigger the issue and the err = -EBUSY, the driver returns NETDEV_TX_BUSY. The network stack retries to transmit the message. Otherwise, it prints an error and discards the message.

[PATCH 1/1] x86/pci: Skip early E820 check for ECAM region

On the Lenovo Legion 9i laptop, that commit removes the area containing ECAM from E820, which means the early E820 validation started failing, which meant we didn't enable ECAM in the "early MCFG" path The lack of ECAM caused many ACPI methods to fail, resulting in the embedded controller, PS/2, audio, trackpad, and battery devices not being detected.

[PATCH v2] arm64/mm: pmd_mkinvalid() must handle swap pmds

__split_huge_pmd_locked() can be called for a present THP, devmap or (non-present) migration entry. It calls pmdp_invalidate() unconditionally on the pmdp and only determines if it is present or not based on the returned old pmd. But arm64's pmd_mkinvalid(), called by pmdp_invalidate(), unconditionally sets the PMD_PRESENT_INVALID flag, which causes future pmd_present() calls to return true - even for a swap pmd. Therefore any lockless pgtable walker could see the migration entry pmd in this state and start interpretting the fields (e.g. pmd_pfn()) as if it were present, leading to BadThings (TM). GUP-fast appears to be one such lockless pgtable walker. While the obvious fix is for core-mm to avoid such calls for non-present pmds (pmdp_invalidate() will also issue TLBI which is not necessary for this case either), all other arches that implement pmd_mkinvalid() do it in such a way that it is robust to being called with a non-present pmd. So it is simpler and safer to make arm64 robust too. This approach means we can even add tests to debug_vm_pgtable.c to validate the required behaviour. This is a theoretical bug found during code review. I don't have any test case to trigger it in practice. Cc: stable(a)vger.kernel.org Fixes: 53fa117bb33c ("arm64/mm: Enable THP migration") Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> --- Hi all, v1 of this fix [1] took the approach of fixing core-mm to never call pmdp_invalidate() on a non-present pmd. But Zi Yan highlighted that only arm64 suffers this problem; all other arches are robust. So his suggestion was to instead make arm64 robust in the same way and add tests to validate it. Despite my stated reservations in the context of the v1 discussion, having thought on it for a bit, I now agree with Zi Yan. Hence this post. Andrew has v1 in mm-unstable at the moment, so probably the best thing to do is remove it from there and have this go in through the arm64 tree? Assuming there is agreement that this approach is right one. This applies on top of v6.9-rc5. Passes all the mm selftests on arm64.

[PATCH v2] serial: sc16is7xx: fix bug in sc16is7xx_set_baud() when using prescaler

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> When using a high speed clock with a low baud rate, the 4x prescaler is automatically selected if required. In that case, sc16is7xx_set_baud() properly configures the chip registers, but returns an incorrect baud rate by not taking into account the prescaler value. This incorrect baud rate is then fed to uart_update_timeout(). For example, with an input clock of 80MHz, and a selected baud rate of 50, sc16is7xx_set_baud() will return 200 instead of 50. Fix this by first changing the prescaler variable to hold the selected prescaler value instead of the MCR bitfield. Then properly take into account the selected prescaler value in the return value computation. Also add better documentation about the divisor value computation.

Part of this glue code are the local functions `__init` and `__exit` that are used to initialize/destroy the Rust module. These functions are safe and also visible to the Rust mod in which the `module!` macro is invoked. This means that they can be called by other safe Rust code. But since they contain `unsafe` blocks that rely on only being called at the right time, this is a soundness issue. Wrap these generated functions inside of two private modules, this guarantees that the public functions cannot be called from the outside. Make the safe functions `unsafe` and add SAFETY comments.

Part of this glue code are the local functions `__init` and `__exit` that are used to initialize/destroy the Rust module. These functions are safe and also visible to the Rust mod in which the `module!` macro is invoked. This means that they can be called by other safe Rust code. But since they contain `unsafe` blocks that rely on only being called at the right time, this is a soundness issue. Wrap these generated functions inside of two private modules, this guarantees that the public functions cannot be called from the outside. Make the safe functions `unsafe` and add SAFETY comments.

[PATCH v2 3/3] Bluetooth: qca: generalise device address check

by Johan Hovold

The default device address apparently comes from the NVM configuration file and can differ quite a bit between controllers. Store the default address when parsing the configuration file and use it to determine whether the controller has been provisioned with an address. This makes sure that devices without a unique address start as unconfigured unless a valid address has been provided in the devicetree.

If the mptcp worker (dumbly) tries mptcp-level re-injection after such ack, that would unconditionally trigger a send buffer cleanup using 'bad' snd_una values. We could easily disable re-injection for fallback sockets, but such dumb behavior already helped catching a few subtle issues and a very low to zero impact in practice. Instead address the issue always initializing snd_nxt (and write_seq, for consistency) at connect time.

[PATCH net] e1000e: change usleep_range to udelay in PHY mdic access

by Tony Nguyen

From: Vitaly Lifshits <vitaly.lifshits(a)intel.com> This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround for sporadic MDI error on Meteor Lake systems"). The referenced commit used usleep_range inside the PHY access routines, which are sometimes called from an atomic context. This can lead to a kernel panic in some scenarios, such as cable disconnection and reconnection on vPro systems. Solve this by changing the usleep_range calls back to udelay.

[PATCH] drm/xe: Unmap userptr in MMU invalidation notifier

by Matthew Brost

To be secure, when a userptr is invalidated the pages should be dma unmapped ensuring the device can no longer touch the invalidated pages.

[PATCH] crypto: arm64: use simd_skcipher_create() when registering aes internal algs

by Liam Kearney

The arm64 crypto drivers duplicate driver names when adding simd variants, which after backported commit 27016f75f5ed ("crypto: api - Disallow identical driver names"), causes an error that leads to the aes algs not being installed. On weaker processors this results in hangs due to falling back to SW crypto. Use simd_skcipher_create() as it will properly namespace the new algs. This issue does not exist in mainline/latest (and stable v6.1+) as the driver has been refactored to remove the simd algs from this code path.
