Pull Documentation updates from Jonathan Corbet: "It's been a relatively busy cycle for docs: - A fair pile of RST conversions, many from Mauro. These create more than the usual number of simple but annoying merge conflicts with other trees, unfortunately. He has a lot more of these waiting on the wings that, I think, will go to you directly later on. - A new document on how to use merges and rebases in kernel repos, and one on Spectre vulnerabilities. - Various improvements to the build system, including automatic markup of function() references because some people, for reasons I will never understand, were of the opinion that :c:func:``function()`` is unattractive and not fun to type. - We now recommend using sphinx 1.7, but still support back to 1.4. - Lots of smaller improvements, warning fixes, typo fixes, etc" * tag 'docs-5.3' of git://git.lwn.net/linux: (129 commits) docs: automarkup.py: ignore exceptions when seeking for xrefs docs: Move binderfs to admin-guide Disable Sphinx SmartyPants in HTML output doc: RCU callback locks need only _bh, not necessarily _irq docs: format kernel-parameters -- as code Doc : doc-guide : Fix a typo platform: x86: get rid of a non-existent document Add the RCU docs to the core-api manual Documentation: RCU: Add TOC tree hooks Documentation: RCU: Rename txt files to rst Documentation: RCU: Convert RCU UP systems to reST Documentation: RCU: Convert RCU linked list to reST Documentation: RCU: Convert RCU basic concepts to reST docs: filesystems: Remove uneeded .rst extension on toctables scripts/sphinx-pre-install: fix out-of-tree build docs: zh_CN: submitting-drivers.rst: Remove a duplicated Documentation/ Documentation: PGP: update for newer HW devices Documentation: Add section about CPU vulnerabilities for Spectre Documentation: platform: Delete x86-laptop-drivers.txt docs: Note that :c:func: should no longer be used ...

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers. Goal is to make use of it on x86 too. - Generic IOMMU domain support for the Intel VT-d driver. This driver now makes more use of common IOMMU code to allocate default domains for the devices it handles. - An IOMMU fault reporting API to userspace. With that the IOMMU fault handling can be done in user-space, for example to forward the faults to a VM. - Better handling for reserved regions requested by the firmware. These can be 'relaxed' now, meaning that those don't prevent a device being attached to a VM. - Suspend/Resume support for the Renesas IOMMU driver. - Added support for dumping SVA related fields of the DMAR table in the Intel VT-d driver via debugfs. - A pile of smaller fixes and cleanups. * tag 'iommu-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (90 commits) iommu/omap: No need to check return value of debugfs_create functions iommu/arm-smmu-v3: Invalidate ATC when detaching a device iommu/arm-smmu-v3: Fix compilation when CONFIG_CMA=n iommu/vt-d: Cleanup unused variable iommu/amd: Flush not present cache in iommu_map_page iommu/amd: Only free resources once on init error iommu/amd: Move gart fallback to amd_iommu_init iommu/amd: Make iommu_disable safer iommu/io-pgtable: Support non-coherent page tables iommu/io-pgtable: Replace IO_PGTABLE_QUIRK_NO_DMA with specific flag iommu/io-pgtable-arm: Add support to use system cache iommu/arm-smmu-v3: Increase maximum size of queues iommu/vt-d: Silence a variable set but not used iommu/vt-d: Remove an unused variable "length" iommu: Fix integer truncation iommu: Add padding to struct iommu_fault iommu/vt-d: Consolidate domain_init() to avoid duplication iommu/vt-d: Cleanup after delegating DMA domain to generic iommu iommu/vt-d: Fix suspicious RCU usage in probe_acpi_namespace_devices() iommu/vt-d: Allow DMA domain attaching to rmrr locked device ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the big slew of GPIO changes for the v5.3 kernel cycle. This is mostly incremental work this time. Three important things: - The FMC subsystem is deleted through my tree. This happens through GPIO as its demise was discussed in relation to a patch decoupling its GPIO implementation from the standard way of handling GPIO. As it turns out, that is not the only subsystem it reimplements and the authors think it is better do scratch it and start over using the proper kernel subsystems than try to polish the rust shiny. See the commit (ACKed by the maintainers) for details. - Arnd made a small devres patch that was ACKed by Greg and goes into the device core. - SPDX header change colissions may happen, because at times I've seen that quite a lot changed during the -rc:s in regards to SPDX. (It is good stuff, tglx has me convinced, and it is worth the occasional pain.) Apart from this is is nothing controversial or problematic. Summary: Core: - When a gpio_chip request GPIOs from itself, it can now fully control the line characteristics, both machine and consumer flags. This makes a lot of sense, but took some time before I figured out that this is how it has to work. - Several smallish documentation fixes. New drivers: - The PCA953x driver now supports the TI TCA9539. - The DaVinci driver now supports the K3 AM654 SoCs.

Future commits will be able to add additional subject types, such as specific UIDs or domain tags/namespaces. Also split a number of permissions to give finer control. Examples include splitting the revocation permit from the change-attributes permit, thereby allowing someone to be granted permission to revoke a key without allowing them to change the owner; also the ability to join a keyring is split from the ability to link to it, thereby stopping a process accessing a keyring by joining it and thus acquiring use of possessor permits. - Provide a keyctl to allow the granting or denial of one or more permits to a specific subject.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull keyring namespacing from David Howells: "These patches help make keys and keyrings more namespace aware. Firstly some miscellaneous patches to make the process easier: - Simplify key index_key handling so that the word-sized chunks assoc_array requires don't have to be shifted about, making it easier to add more bits into the key. - Cache the hash value in the key so that we don't have to calculate on every key we examine during a search (it involves a bunch of multiplications). - Allow keying_search() to search non-recursively. Then the main patches: - Make it so that keyring names are per-user_namespace from the point of view of KEYCTL_JOIN_SESSION_KEYRING so that they're not accessible cross-user_namespace. keyctl_capabilities() shows KEYCTL_CAPS1_NS_KEYRING_NAME for this. - Move the user and user-session keyrings to the user_namespace rather than the user_struct. This prevents them propagating directly across user_namespaces boundaries (ie. the KEY_SPEC_* flags will only pick from the current user_namespace). - Make it possible to include the target namespace in which the key shall operate in the index_key. This will allow the possibility of multiple keys with the same description, but different target domains to be held in the same keyring. keyctl_capabilities() shows KEYCTL_CAPS1_NS_KEY_TAG for this. - Make it so that keys are implicitly invalidated by removal of a domain tag, causing them to be garbage collected. - Institute a network namespace domain tag that allows keys to be differentiated by the network namespace in which they operate. New keys that are of a type marked 'KEY_TYPE_NET_DOMAIN' are assigned the network domain in force when they are created. - Make it so that the desired network namespace can be handed down into the request_key() mechanism. This allows AFS, NFS, etc. to request keys specific to the network namespace of the superblock. This also means that the keys in the DNS record cache are thenceforth namespaced, provided network filesystems pass the appropriate network namespace down into dns_query(). For DNS, AFS and NFS are good, whilst CIFS and Ceph are not.

Note that the key must be in the caller's keyrings already to be found. - Invalidate used request_key authentication keys rather than revoking them, so that they get cleaned up immediately rather than hanging around till the expiry time is passed. - Move the RCU locks outwards from the keyring search functions so that a request_key_rcu() can be provided. This can be called in RCU mode, so it can't sleep and can't upcall - but it can be called from LOOKUP_RCU pathwalk mode. - Cache the latest positive result of request_key*() temporarily in task_struct so that filesystems that make a lot of request_key() calls during pathwalk can take advantage of it to avoid having to redo the searching.

Pull tpm updates from Jarkko Sakkinen: "This contains two critical bug fixes and support for obtaining TPM events triggered by ExitBootServices(). For the latter I have to give a quite verbose explanation not least because I had to revisit all the details myself to remember what was going on in Matthew's patches. The preboot software stack maintains an event log that gets entries every time something gets hashed to any of the PCR registers. What gets hashed could be a component to be run or perhaps log of some actions taken just to give couple of coarse examples. In general, anything relevant for the boot process that the preboot software does gets hashed and a log entry with a specific event type [1]. The main application for this is remote attestation and the reason why it is useful is nicely put in the very first section of [1]: "Attestation is used to provide information about the platform’s state to a challenger. However, PCR contents are difficult to interpret; therefore, attestation is typically more useful when the PCR contents are accompanied by a measurement log. While not trusted on their own, the measurement log contains a richer set of information than do the PCR contents. The PCR contents are used to provide the validation of the measurement log." Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling ExitBootServices(), Linux EFI stub copies the event log to a custom configuration table. Unfortunately, ExitBootServices() also generates events and obviously these events do not get copied to that table. Luckily firmware does this for us by providing a configuration table identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID. This essentially contains necessary changes to provide the full event log for the use the user space that is concatenated from these two partial event logs [2]" [1] https://trustedcomputinggroup.org/resource/pc-client-specific-platform-firmware-profile-specification/ [2] The final concatenation is done in drivers/char/tpm/eventlog/efi.c * tag 'tpmdd-next-20190625' of git://git.infradead.org/users/jjs/linux-tpmdd: tpm: Don't duplicate events from the final event log in the TCG2 log Abstract out support for locating an EFI config table tpm: Fix TPM 1.2 Shutdown sequence to prevent future TPM operations efi: Attempt to get the TCG2 event log in the boot stub tpm: Append the final event log to the TPM event log tpm: Reserve the TPM final events table tpm: Abstract crypto agile event size calculations tpm: Actually fail on TPM errors during "get random"

Another microbenchmark shows how across the spectrum the improvements are: "With a locking microbenchmark running on 5.1 based kernel, the total locking rates (in kops/s) on a 2-socket Skylake system with equal numbers of readers and writers (mixed) before and after this patchset were: # of Threads Before Patch After Patch ------------ ------------ ----------- 2 2,618 4,193 4 1,202 3,726 8 802 3,622 16 729 3,359 32 319 2,826 64 102 2,744" The changes are extensive and the patch-set has been through several iterations addressing various locking workloads. There might be more regressions, but unless they are pathological I believe we want to use this new implementation as the baseline going forward. - jump-label optimizations by Daniel Bristot de Oliveira: the primary motivation was to remove IPI disturbance of isolated RT-workload CPUs, which resulted in the implementation of batched jump-label updates. Beyond the improvement of the real-time characteristics kernel, in one test this patchset improved static key update overhead from 57 msecs to just 1.4 msecs - which is a nice speedup as well. - atomic64_t cross-arch type cleanups by Mark Rutland: over the last ~10 years of atomic64_t existence the various types used by the APIs only had to be self-consistent within each architecture - which means they became wildly inconsistent across architectures. Mark puts and end to this by reworking all the atomic64 implementations to use 's64' as the base type for atomic64_t, and to ensure that this type is consistently used for parameters and return values in the API, avoiding further problems in this area. - A large set of small improvements to lockdep by Yuyang Du: type cleanups, output cleanups, function return type and othr cleanups all around the place. - A set of percpu ops cleanups and fixes by Peter Zijlstra. - Misc other changes - please see the Git log for more details" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (82 commits) locking/lockdep: increase size of counters for lockdep statistics locking/atomics: Use sed(1) instead of non-standard head(1) option locking/lockdep: Move mark_lock() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING x86/jump_label: Make tp_vec_nr static x86/percpu: Optimize raw_cpu_xchg() x86/percpu, sched/fair: Avoid local_clock() x86/percpu, x86/irq: Relax {set,get}_irq_regs() x86/percpu: Relax smp_processor_id() x86/percpu: Differentiate this_cpu_{}() and __this_cpu_{}() locking/rwsem: Guard against making count negative locking/rwsem: Adaptive disabling of reader optimistic spinning locking/rwsem: Enable time-based spinning on reader-owned rwsem locking/rwsem: Make rwsem->owner an atomic_long_t locking/rwsem: Enable readers spinning on writer locking/rwsem: Clarify usage of owner's nonspinaable bit locking/rwsem: Wake up almost all readers in wait queue locking/rwsem: More optimal RT task handling of null owner locking/rwsem: Always release wait_lock before waking up tasks locking/rwsem: Implement lock handoff to prevent lock starvation locking/rwsem: Make rwsem_spin_on_owner() return owner state ...
