git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - Fix virtual vs physical address confusion in vmem_add_range() and vmem_remove_range() functions - Include <linux/io.h> instead of <asm/io.h> and <asm-generic/io.h> throughout s390 code - Make all PSW related defines also available for assembler files. Remove PSW_DEFAULT_KEY define from uapi for that - When adding an undefined symbol the build still succeeds, but userspace crashes trying to execute VDSO, because the symbol is not resolved. Add undefined symbols check to prevent that - Use kvmalloc_array() instead of kzalloc() for allocaton of 256k memory when executing s390 crypto adapter IOCTL - Add -fPIE flag to prevent decompressor misaligned symbol build error with clang - Use .balign instead of .align everywhere. This is a no-op for s390, but with this there no mix in using .align and .balign anymore - Filter out -mno-pic-data-is-text-relative flag when compiling kernel to prevent VDSO build error - Rework entering of DAT-on mode on CPU restart to use PSW_KERNEL_BITS mask directly - Do not retry administrative requests to some s390 crypto cards, since the firmware assumes replay attacks - Remove most of the debug code, which is build in when kernel config option CONFIG_ZCRYPT_DEBUG is enabled - Remove CONFIG_ZCRYPT_MULTIDEVNODES kernel config option and switch off the multiple devices support for the s390 zcrypt device driver - With the conversion to generic entry machine checks are accounted to the current context instead of irq time. As result, the STCKF instruction at the beginning of the machine check handler and the lowcore member are no longer required, therefore remove it - Fix various typos found with codespell - Minor cleanups to CPU-measurement Counter and Sampling Facilities code - Revert patch that removes VMEM_MAX_PHYS macro, since it causes a regression * tag 's390-6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (25 commits) Revert "s390/mm: get rid of VMEM_MAX_PHYS macro" s390/cpum_sf: remove check on CPU being online s390/cpum_sf: handle casts consistently s390/cpum_sf: remove unnecessary debug statement s390/cpum_sf: remove parameter in call to pr_err s390/cpum_sf: simplify function setup_pmu_cpu s390/cpum_cf: remove unneeded debug statements s390/entry: remove mcck clock s390: fix various typos s390/zcrypt: remove ZCRYPT_MULTIDEVNODES kernel config option s390/zcrypt: do not retry administrative requests s390/zcrypt: cleanup some debug code s390/entry: rework entering DAT-on mode on CPU restart s390/mm: fence off VM macros from asm and linker s390: include linux/io.h instead of asm/io.h s390/ptrace: make all psw related defines also available for asm s390/ptrace: remove PSW_DEFAULT_KEY from uapi s390/vdso: filter out mno-pic-data-is-text-relative cflag s390: consistently use .balign instead of .align s390/decompressor: fix misaligned symbol build error ...

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues

2023-06-23crypto: caam - optimize RNG sample sizeMeenakshi Aggarwal
TRNG "sample size" (the total number of entropy samples that will be taken during entropy generation) default / POR value is very conservatively set to 2500. Let's set it to 512, the same as the caam driver in U-boot (drivers/crypto/fsl_caam.c) does. This solves the issue of RNG performance dropping after a suspend/resume cycle on parts where caam loses power, since the initial U-boot setttings are lost and kernel does not restore them when resuming. Note: when changing the sample size, the self-test parameters need to be updated accordingly.

2023-06-16crypto: qat - extend configuration for 4xxxAdam Guerin
A QAT GEN4 device can be currently configured for crypto (sym;asym) or compression (dc). This patch extends the configuration to support more variations of these services, download the correct FW images on the device and report the correct capabilities on the device based on the configured service. The device can now be configured with the following services: "sym", "asym", "dc", "sym;asym", "asym;sym", "sym;dc", "dc;sym", "asym;dc", "dc;asym". With this change, the configuration "sym", "asym", "sym;dc", "dc;sym", "asym;dc", "dc;asym" will be accessible only via userspace, i.e. the driver for those configurations will not register into the crypto framework. Support for such configurations in kernel will be enabled in a later patch. The pairs "sym;asym" and "asym;sym" result in identical device config. As do "sym;dc", "dc;sym", and "asym;dc", "dc;asym".

2023-06-16crypto: qat - refactor fw config logic for 4xxxGiovanni Cabiddu
The data structure adf_fw_config is used to select which firmware image is loaded on a certain set of accelerator engines. When support for 402xx was added, the adf_fw_config arrays were duplicated in order to select different firmware images. Since the configurations are the same regardless of the QAT GEN4 flavour, in preparation for adding support for multiple configurations, refactor the logic that retrieves the firmware names in the 4xxx driver. The structure adf_fw_config has been changed to contain a firmware object id that is then mapped to a firmware name depending of the device type.

2023-06-02crypto: qat - move dbgfs init to separate fileDamian Muszynski
Move initialization of debugfs entries to a separate file. This simplifies the exclusion of the debugfs logic in the QAT driver when the kernel is built with CONFIG_DEBUG_FS=n. In addition, it will allow to consolidate the addition of debugfs entries to a single location in the code. This implementation adds infrastructure to create (and remove) debugfs entries at two different stages. The first, done when a device is probed, allows to keep debugfs entries persistent between a transition in device state (up to down or vice versa). The second, done after the initialization phase, allows to have debugfs entries that are accessible only when the device is up. In addition, move the creation of debugfs entries for configuration to the newly created function adf_dbgfs_init() and replace symbolic permissions with octal permissions when creating the debugfs files. This is to resolve the following warning reported by checkpatch: WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.

The value returned by an fsl-mc driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero and then device removal continues unconditionally.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2023-05-18crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueuesTejun Heo
BACKGROUND ========== When multiple work items are queued to a workqueue, their execution order doesn't match the queueing order. They may get executed in any order and simultaneously. When fully serialized execution - one by one in the queueing order - is needed, an ordered workqueue should be used which can be created with alloc_ordered_workqueue(). However, alloc_ordered_workqueue() was a later addition. Before it, an ordered workqueue could be obtained by creating an UNBOUND workqueue with @max_active==1. This originally was an implementation side-effect which was broken by 4c16bd327c74 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered"). Because there were users that depended on the ordered execution, 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered") made workqueue allocation path to implicitly promote UNBOUND workqueues w/ @max_active==1 to ordered workqueues. While this has worked okay, overloading the UNBOUND allocation interface this way creates other issues. It's difficult to tell whether a given workqueue actually needs to be ordered and users that legitimately want a min concurrency level wq unexpectedly gets an ordered one instead. With planned UNBOUND workqueue updates to improve execution locality and more prevalence of chiplet designs which can benefit from such improvements, this isn't a state we wanna be in forever. This patch series audits all callsites that create an UNBOUND workqueue w/ @max_active==1 and converts them to alloc_ordered_workqueue() as necessary. WHAT TO LOOK FOR ================ The conversions are from alloc_workqueue(WQ_UNBOUND | flags, 1, args..) to alloc_ordered_workqueue(flags, args...) which don't cause any functional changes. If you know that fully ordered execution is not ncessary, please let me know. I'll drop the conversion and instead add a comment noting the fact to reduce confusion while conversion is in progress. If you aren't fully sure, it's completely fine to let the conversion through. The behavior will stay exactly the same and we can always reconsider later. As there are follow-up workqueue core changes, I'd really appreciate if the patch can be routed through the workqueue tree w/ your acks. Thanks.

2023-05-12crypto: octeontx2 - hardware configuration for inline IPsecSrujana Challa
On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF) handles resource allocation and configuration for PFs and their VFs. PFs request the AF directly, via mailboxes. Unlike PFs, VFs cannot send a mailbox request directly. A VF sends mailbox messages to its parent PF, with which it shares a mailbox region. The PF then forwards these messages to the AF. This patch adds code to configure inline-IPsec HW resources for CPT VFs as CPT VFs cannot send a mailbox request directly to AF.
