cxl for 5.18
- Add a driver for 'struct cxl_memdev' objects responsible for CXL.mem operation as distinct from 'cxl_pci' mailbox operations. Its primary responsibility is enumerating an endpoint 'struct cxl_port' and all the 'struct cxl_port' instances between an endpoint and the CXL platform root. - Add a driver for 'struct cxl_port' objects responsible for enumerating and operating all Host-managed Device Memory (HDM) decoder resources between the platform-level CXL memory description, all intervening host bridges / switches, and the HDM resources in endpoints. - Update the cxl_pci driver to validate CXL.mem operation precursors to HDM decoder operation like ready-polling, and legacy CXL 1.1 DVSEC based CXL.mem configuration. - Add basic lockdep coverage for usage of device_lock() on CXL subsystem objects similar to what exists for LIBNVDIMM. Include a compile-time switch for which subsystem to validate at run-time. - Update cxl_test to emulate a one level switch topology. - Document a "Theory of Operation" for the subsystem. - Add 'numa_node' and 'serial' attributes to cxl_memdev sysfs - Include miscellaneous fixes for spec / QEMU CXL emulation compatibility and static analysis reports. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQSbo+XnGs+rwLz9XGXfioYZHlFsZwUCYjpX6AAKCRDfioYZHlFs ZzyxAQCztxAXj7mzkm1Qt5zZz4e7p/6sR49B03jBTfPtrEF9kQEAl9R15WVt6U+o Ooof1XhRic3kT6e8zS3ZVKHzGduYxwM= =mR94 -----END PGP SIGNATURE----- Merge tag 'cxl-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull CXL (Compute Express Link) updates from Dan Williams: "This development cycle extends the subsystem to discover CXL resources throughout a CXL/PCIe switch topology and respond to hot add/remove events anywhere in that topology.

Networking changes for 5.18.
Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port.

Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port. Support NS/NA monitor selection similar to existing ARP monitor. - SMC - improve performance with TCP_CORK and sendfile() - support auto-corking - support TCP_NODELAY - MCTP (Management Component Transport Protocol) - add user space tag control interface - I2C binding driver (as specified by DMTF DSP0237) - Multi-BSSID beacon handling in AP mode for WiFi. - Bluetooth: - handle MSFT Monitor Device Event - add MGMT Adv Monitor Device Found/Lost events - Multi-Path TCP: - add support for the SO_SNDTIMEO socket option - lots of selftest cleanups and improvements - Increase the max PDU size in CAN ISOTP to 64 kB.

asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree: - The set_fs()/get_fs() infrastructure gets removed for good. This was already gone from all major architectures, but now we can finally remove it everywhere, which loses some particularly tricky and error-prone code. There is a small merge conflict against a parisc cleanup, the solution is to use their new version. - The nds32 architecture ends its tenure in the Linux kernel. The hardware is still used and the code is in reasonable shape, but the mainline port is not actively maintained any more, as all remaining users are thought to run vendor kernels that would never be updated to a future release. There are some obvious conflicts against changes to the removed files. - A series from Masahiro Yamada cleans up some of the uapi header files to pass the compile-time checks. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmI69BsACgkQmmx57+YA GNn/zA//f4d5VTT0ThhRxRWTu9BdThGHoB8TUcY7iOhbsWu0X/913NItRC3UeWNl IdmisaXgVtirg1dcC2pWUmrcHdoWOCEGfK4+Zr2NhSWfuZDWvODHK9pGWk4WLnhe cQgUNBvIuuAMryGtrOBwHPO4TpfCyy2ioeVP36ZfcsWXdDxTrqfaq/56mk3sxIP6 sUTk1UEjut9NG4C9xIIvcSU50R3l6LryQE/H9kyTLtaSvfvTOvprcVYCq0GPmSzo DtQ1Wwa9zbJ+4EqoMiP5RrgQwWvOTg2iRByLU8ytwlX3e/SEF0uihvMv1FQbL8zG G8RhGUOKQSEhaBfc3lIkm8GpOVPh0uHzB6zhn7daVmAWtazRD2Nu59BMjipa+ims a8Z58iHH7jRAnKeEkVZqXKb1CEiUxaQx/IeVPzN4QlwMhDtwrI76LY7ZJ1zCqTGY ENG0yRLav1XselYBslOYXGtOEWcY5EZPWqLyWbp4P9vz2g0Fe0gZxoIOvPmNQc89 QnfXpCt7vm/DGkyO255myu08GOLeMkisVqUIzLDB9avlym5mri7T7vk9abBa2YyO CRpTL5gl1/qKPWuH1UI5mvhT+sbbBE2SUHSuy84btns39ZKKKynwCtdu+hSQkKLE h9pV30Gf1cLTD4JAE0RWlUgOmbBLVp34loTOexQj4MrLM1noOnw= =vtCN -----END PGP SIGNATURE----- Merge tag 'asm-generic-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are three sets of updates for 5.18 in the asm-generic tree: - The set_fs()/get_fs() infrastructure gets removed for good.

sound updates for 5.18
It's been a fairly calm development cycle. There are a few last-minute ALSA core fixes, most notably for covering PCM ioctl races, but the most of rest are device-specific changes. Below are some highlights: * ALSA core: - Fixes for PCM ioctl races that may lead to UAF - Fix for oversized allocations in PCM OSS layer * ASoC: - Start of moving SoF to support multiple IPC mechanisms - Use of NHLT ACPI table to reduce the amount of quirking required for Intel systems - Preliminary works forthcoming Intel AVS driver for legacy Intel DSP firmwares - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas RZ/V2L, Texas Instruments TAS585M * HD-audio: - Driver re-binding fix for HD-audio - Updates for Intel ADL and Tegra234, various platform quirks for Dell, HP, Lenovo, ASUS, Samsung and Clevo machines * USB-audio: - Quirk updates for Scarlett2, RODE, Corsair devices -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmI7AkUOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE/faBAAvPFODmyJlt16UG7bSlqwoSafWho+Bp4GSH4O +pEm47+kULgkKOm9k2NK7sci6nOsNIabQsVhMeryCLgDlNlFqR4FQjIswbgtRWsO lmu3TMw26I0vS2joNE+tpqCOyJuEGI/ekQru3aKAZx6JyBlXmrzuf7L4BNomVORr fgBgpMg/tRcE9ceWjc1qHMggueAfkcjnI4ioFYxaWYXp4wyVX1mx3mVHEf6WQnff ZXsgQLhupUKLvyBr2D1vkN6JcRyTahkBprbLEtZhKszR8hl6tFlnyILkzsiZ/B+K oJAvtEoC6z2PW+suPSPPl2qnbyOJyX32m43iCXW8uSG1KG/K2JshZIJshMbVw3pV rLK3XYr2zoE3VzzNUL+QyGYhLpdDPSNF+E19z7jfWU/wKwCUu8qWuejhf9uAlQgx XtlrZuyCpnsNVyILqLM2Sgzvc1U8vJd68uYwhecchTmP0Aurld5NM2PiAagcvVpW RtEMbTJbIBYbou3UPhxDjEdQOeT+KZUYrClEjb61pJQ9sHAbC4l0LoRyS4NEWCZH J7Z5DNPqPf6CFU1AVpfktL4Dh+VtM7nb4DVyyyLWWZgG3NcXSVLLbUA8Uo9qoDV5 7tHnV+1MURBwEq1CUvZtb3sRC5tyNVkzXMMAJfcVWlv7JkoXs8pzwK9w685aP2zl YDOfau8= =5cCU -----END PGP SIGNATURE----- Merge tag 'sound-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "It's been a fairly calm development cycle.

Tracing updates for 5.18:
- New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer. - Add new "ftrace_boot_snapshot" kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well. - Have TRACE_EVENT_ENUM() also update trace event field type descriptions. Thus if a static array defines its size with an enum, the user space trace event parsers can still know how to parse that array. - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the TRACE_EVENT() macro, but will attach to an existing tracepoint. This will make one tracepoint be able to trace different content and not be stuck at only what the original TRACE_EVENT() macro exports. - Fixes to tracing error logging. - Better saving of cmdlines to PIDs when tracing (use the wakeup events for mapping). -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYjiO3RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhQzAQDtek5p80p/zkMGymm14wSH6qq0NdgN Kv7fTBwEewUa0gD/UCOVLw4Oj+JtHQhCa3sCGZopmRv0BT1+4UQANqosKQY= =Au08 -----END PGP SIGNATURE----- Merge tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - New user_events interface.

selftests: vm: add a hugetlb test case
Since the head vmemmap page frame associated with each HugeTLB page is reused, we should hide the PG_head flag of tail struct page from the user. Add a tese case to check whether it is work properly. The test steps are as follows. 1) alloc 2MB hugeTLB 2) get each page frame 3) apply those APIs in each page frame 4) Those APIs work completely the same as before. Reading the flags of a page by /proc/kpageflags is done in stable_page_flags(), which has invoked PageHead(), PageTail(), PageCompound() and compound_head(). If those APIs work properly, the head page must have 15 and 17 bits set. And tail pages must have 16 and 17 bits set but 15 bit unset. Those flags are checked in check_page_flags().

selftests, x86: fix how check_cc.sh is being invoked
The $(CC) variable used in Makefiles could contain several arguments
such as "ccache gcc". These need to be passed as a single string to
check_cc.sh, otherwise only the first argument will be used as the
compiler command. Without quotes, the $(CC) variable is passed as
distinct arguments which causes the script to fail to build trivial
programs.
Fix this by adding quotes around $(CC) when calling check_cc.sh to pass
the whole string as a single argument to the script even if it has
several words such as "ccache gcc".

selftests: memcg: test high limit for single entry allocation
Test the enforcement of memory.high limit for large amount of memory allocation within a single kernel entry. There are valid use-cases where the application can trigger large amount of memory allocation within a single syscall e.g. mlock() or mmap(MAP_POPULATE). Make sure memory.high limit enforcement works for such use-cases.

bpftool: Fix a bug in subskeleton code generation
Compiled with clang by adding LLVM=1 both kernel and selftests/bpf
build, I hit the following compilation error:
In file included from /.../tools/testing/selftests/bpf/prog_tests/subskeleton.c:6:

errno = -err;
^~~
./test_subskeleton_lib.subskel.h:168:2: note: remove the 'if' if its condition is always false
if (!s->progs)
^~~~~~~~~~~~~~
The compilation error is triggered by the following code
...
int err;
obj = (struct test_subskeleton_lib *)calloc(1, sizeof(*obj));
if (!obj) {
errno = ENOMEM;
goto err;
}
...
err:
test_subskeleton_lib__destroy(obj);
errno = -err;
...
in test_subskeleton_lib__open(). The 'err' is not initialized, yet it
is used in 'errno = -err' later.
The fix is to remove 'errno = -err' since errno has been set properly
in all incoming branches.

Specifics: - Add a new thermal driver for the Intel Hardware Feedback Interface (HFI) including the HFI initialization, HFI notification interrupt handling and sending CPU capabilities change messages to user space via the thermal netlink interface (Ricardo Neri, Srinivas Pandruvada, Nathan Chancellor, Randy Dunlap). - Extend the intel-speed-select utility to handle out-of-band CPU configuration changes and add support for the CPU capabilities change messages sent over the thermal netlink interface by the new HFI thermal driver to it (Srinivas Pandruvada). - Convert the DT bindings to yaml format for the Exynos platform and fix and update the MAINTAINERS file for this driver (Krzysztof Kozlowski). - Register the thermal zones as HWmon sensors for the QCom's Tsens driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour). - Add the msm8953 compatible documentation in the bindings (Luca Weiss). - Add the sm8150 platform support to the QCom LMh driver's DT binding (Thara Gopinath). - Check the command result from the IPC command to the BPMP in the Tegra driver (Mikko Perttunen). - Silence the error for normal configuration where the interrupt is optionnal in the Broadcom thermal driver (Florian Fainelli). - Remove remaining dead code from the TI thermal driver (Yue Haibing). - Don't use bitmap_weight() in end_power_clamp() in the powerclamp driver (Yury Norov). - Update the OS policy capabilities handshake in the int340x thermal driver (Srinivas Pandruvada). - Increase the policies bitmap size in int340x (Srinivas Pandruvada). - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the int340x thermal driver (Rafael Wysocki). - Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang). - Add Intel Dynamic Power and Thermal Framework (DPTF) kernel interface documentation (Srinivas Pandruvada). - Fix bullet list warning in the thermal documentation (Randy Dunlap)" * tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (30 commits) thermal: int340x: Update OS policy capability handshake thermal: int340x: Increase bitmap size Documentation: thermal: DPTF Documentation MAINTAINERS: thermal: samsung: update Krzysztof Kozlowski's email thermal/drivers/ti-soc-thermal: Remove unused function ti_thermal_get_temp() thermal/drivers/brcmstb_thermal: Interrupt is optional thermal: tegra-bpmp: Handle errors in BPMP response drivers/thermal/ti-soc-thermal: Add hwmon support dt-bindings: thermal: tsens: Add msm8953 compatible dt-bindings: thermal: Add sm8150 compatible string for LMh thermal/drivers/qcom/lmh: Add support for sm8150 thermal/drivers/tsens: register thermal zones as hwmon sensors MAINTAINERS: thermal: samsung: Drop obsolete properties dt-bindings: thermal: samsung: Convert to dtschema tools/power/x86/intel-speed-select: v1.12 release tools/power/x86/intel-speed-select: HFI support tools/power/x86/intel-speed-select: OOB daemon mode thermal: intel: hfi: INTEL_HFI_THERMAL depends on NET thermal: netlink: Fix parameter type of thermal_genl_cpu_capability_event() stub thermal: Replace acpi_bus_get_device() ... |

Reenable ENQCMD/PASID support:
- Simplify the PASID handling to allocate the PASID once, associate it to the mm of a process and free it on mm_exit(). The previous attempt of refcounted PASIDs and dynamic alloc()/free() turned out to be error prone and too complex. The PASID space is 20bits, so the case of resource exhaustion is a pure academic concern. - Populate the PASID MSR on demand via #GP to avoid racy updates via IPIs. - Reenable ENQCMD and let objtool check for the forbidden usage of ENQCMD in the kernel. - Update the documentation for Shared Virtual Addressing accordingly. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmI4WpETHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoUfnD/0bY94rgEX4Uuy/mFQ1W8X8XlcyKrha 0/cRATb+4QV/pwJgGr2nClKhGlFMYPdJLvKMC1TCUPCVrLD1RNmluIZoFzeqXwhm jDdCcFOuGZ2D4ujDPWwOOpKBT1ytovnQa7+lH6QJyKkEqdcC2ncOvGJQoiRxRQIG 8wTVs/OUvQJ5ZhSZQMKQN4uMWMyHEjhbroYS30/uNi/598jTPgzlEoa14XocQ9Os nS6ALvjuc9MsJ34F61etMaJU1ZMI3Wx75u9QjEvX6hmJs87YdvgwE7lzJUKFDEuh gewM0wp2fTa8/azzP0eMiHTin56PqFdmllzRqXmilbZMEPOeI29dZVArCdpKcAn0 r9p1kJUT3Xl2G3Oir/OdCaaQHcznD1Y5ZFOyh12wgEucZ/rdeSr7nq7n5HoOL5Bw Q2o6YvTkE9DOL0nTN1lSXGiPspou7fzX0uUcRBrbJUS3sBv4zGIlaJXUaTVnSdAt VZj4LeOK7v2BjyeiOY0iaaIQd3xjmLUF0UjozXS5M13SoVcToZRbyWqhDzPvNuKA imQb/dnFpXhABgmuqAiJLeqM0VtGMFNc780OURkcsBSPng+iSEdV4DzuhK0jpU8x Uk1RuGMd/vgmrlDFBrw+orQQiiKR1ixpI0LiHfcOBycfJhqTwcnrNZvAN5/do28Z E23+QzlUbZF0cw== =Dy8V -----END PGP SIGNATURE----- Merge tag 'x86-pasid-2022-03-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 PASID support from Thomas Gleixner: "Reenable ENQCMD/PASID support: - Simplify the PASID handling to allocate the PASID once, associate it to the mm of a process and free it on mm_exit().

For TPM the patches worth of highlighting are the fixes for refcounting provided by Lino Sanfilippo and James Bottomley. Eric B. has done a bunch obvious (but important) fixes but there's one a bit controversial: removal of asym_tpm. It was added in 2018 when TPM1 was already declared as insecure and world had moved on to TPM2. I don't know how this has passed all the filters but I did not have a chance to see the patches when they were out. I simply cannot commit to maintaining this because it was from all angles just wrong to take it in the first place to the mainline kernel. Nobody should use this module really for anything. Finally, there is a new keyring '.machine' to hold MOK keys ('Machine Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be set, from which kernel knows that MOK keys are kernel trusted keys and they are populated to the machine keyring. This keyring linked to the secondary trusted keyring, which means that can be used like any kernel trusted keys. This keyring of course can be used to hold other MOK'ish keys in other platforms in future" * tag 'tpmdd-next-v5.18-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd: (24 commits) tpm: use try_get_ops() in tpm-space.c KEYS: asymmetric: properly validate hash_algo and encoding KEYS: asymmetric: enforce that sig algo matches key algo KEYS: remove support for asym_tpm keys tpm: fix reference counting for struct tpm_chip integrity: Only use machine keyring when uefi_check_trust_mok_keys is true integrity: Trust MOK keys if MokListTrustedRT found efi/mokvar: move up init order KEYS: Introduce link restriction for machine keys KEYS: store reference to machine keyring integrity: add new keyring handler for mok keys integrity: Introduce a Linux keyring called machine integrity: Fix warning about missing prototypes KEYS: trusted: Avoid calling null function trusted_key_exit KEYS: trusted: Fix trusted key backends when building as module tpm: xen-tpmfront: Use struct_size() helper KEYS: x509: remove dead code that set ->unsupported_sig KEYS: x509: remove never-set ->unsupported_key flag KEYS: x509: remove unused fields KEYS: x509: clearly distinguish between key and signature algorithms ... |

bpftool: Fix print error when show bpf map
If there is no btf_id or frozen, it will not show the pids, but the pids don't
depend on any one of them.
Below is the result after this change:
$ ./bpftool map show
2: lpm_trie flags 0x1
key 8B value 8B max_entries 1 memlock 4096B
pids systemd(1)
3: lpm_trie flags 0x1
key 20B value 8B max_entries 1 memlock 4096B
pids systemd(1)
While before this change, the 'pids systemd(1)' can't be displayed.

selftests/bpf/test_lirc_mode2.sh: Exit with proper code
When test_lirc_mode2_user exec failed, the test report failed but still
exit with 0. Fix it by exiting with an error code.
Another issue is for the LIRCDEV checking. With bash -n, we need to quote
the variable, or it will always be true. So if test_lirc_mode2_user was
not run, just exit with skip code.

selftests/bpf: Fix test for 4-byte load from remote_port on big-endian
The context access converter rewrites the 4-byte load from
bpf_sk_lookup->remote_port to a 2-byte load from bpf_sk_lookup_kern
structure.
It means that we cannot treat the destination register contents as a 32-bit
value, or the code will not be portable across big- and little-endian
architectures.
This is exactly the same case as with 4-byte loads from bpf_sock->dst_port
so follow the approach outlined in [1] and treat the register contents as a
16-bit value in the test.

selftests/bpf: Test for associating multiple elements with the local storage
This patch adds a few calls to the existing local storage selftest to test that we can associate multiple elements with the local storage. The sleepable program's call to bpf_sk_storage_get with sk_storage_map2 will lead to an allocation of a new selem under the GFP_KERNEL flag.
