Networking changes for 5.17.
Core ---- - Defer freeing TCP skbs to the BH handler, whenever possible, or at least perform the freeing outside of the socket lock section to decrease cross-CPU allocator work and improve latency. - Add netdevice refcount tracking to locate sources of netdevice and net namespace refcount leaks. - Make Tx watchdog less intrusive - avoid pausing Tx and restarting all queues from a single CPU removing latency spikes. - Various small optimizations throughout the stack from Eric Dumazet. - Make netdev->dev_addr[] constant, force modifications to go via appropriate helpers to allow us to keep addresses in ordered data structures. - Replace unix_table_lock with per-hash locks, improving performance of bind() calls. - Extend skb drop tracepoint with a drop reason. - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW. BPF --- - New helpers: - bpf_find_vma(), find and inspect VMAs for profiling use cases - bpf_loop(), runtime-bounded loop helper trading some execution time for much faster (if at all converging) verification - bpf_strncmp(), improve performance, avoid compiler flakiness - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt() for tracing programs, all inlined by the verifier - Support BPF relocations (CO-RE) in the kernel loader. - Further the support for BTF_TYPE_TAG annotations. - Allow access to local storage in sleepable helpers. - Convert verifier argument types to a composable form with different attributes which can be shared across types (ro, maybe-null). - Prepare libbpf for upcoming v1.0 release by cleaning up APIs, creating new, extensible ones where missing and deprecating those to be removed. Protocols --------- - WiFi (mac80211/cfg80211): - notify user space about long "come back in N" AP responses, allow it to react to such temporary rejections - allow non-standard VHT MCS 10/11 rates - use coarse time in airtime fairness code to save CPU cycles - Bluetooth: - rework of HCI command execution serialization to use a common queue and work struct, and improve handling errors reported in the middle of a batch of commands - rework HCI event handling to use skb_pull_data, avoiding packet parsing pitfalls - support AOSP Bluetooth Quality Report - SMC: - support net namespaces, following the RDMA model - improve connection establishment latency by pre-clearing buffers - introduce TCP ULP for automatic redirection to SMC - Multi-Path TCP: - support ioctls: SIOCINQ, OUTQ, and OUTQNSD - support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT, IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY - support cmsgs: TCP_INQ - improvements in the data scheduler (assigning data to subflows) - support fastclose option (quick shutdown of the full MPTCP connection, similar to TCP RST in regular TCP) - MCTP (Management Component Transport) over serial, as defined by DMTF spec DSP0253 - "MCTP Serial Transport Binding". Driver API ---------- - Support timestamping on bond interfaces in active/passive mode. - Introduce generic phylink link mode validation for drivers which don't have any quirks and where MAC capability bits fully express what's supported. Allow PCS layer to participate in the validation. Convert a number of drivers. - Add support to set/get size of buffers on the Rx rings and size of the tx copybreak buffer via ethtool. - Support offloading TC actions as first-class citizens rather than only as attributes of filters, improve sharing and device resource utilization. -

SoC: Add support for StarFive JH7100 RISC-V SoC
This adds support for the StarFive JH7100, including the necessary device drivers and DT files for the BeagleV Starlight prototype board, with additional boards to be added later. This SoC promises to be the first usable low-cost platform for RISC-V. I've taken this through the SoC tree in the anticipation of adding a few other Arm based SoCs as well, but those did not pass the review in time, so it's only this one. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmHE4/wACgkQmmx57+YA GNlSlRAArOIWkgB8Uwf2dz1tdyGNo6b0yqrqPBnc2hlafQVkrd/Cy0imIEt21pJk IkVviuuJmWMS7lFppvjoKbTZDvGt4gcA2o//NorBtSLV5G7mbJAMkeDtfdURRAb0 c7IXbtHaI5qMPHXOzjbKTHedbLJpS2P1uXQtGr9hiZFP8ZfyfbEF1bzL0edcCAWi DuY7cpEHEzeKATN8NQ1ETwpx0MJBfp7pzyfQbB9I1VvIMX1qbuLBUUJ6snLGSiw1 kvLrQoV+2ZISeEfQ8M/PoHpHexO7CzY0thlTFt2mThLVI0ZlaVJvI6oJDAX5AG67 tsmDiBxzvp+gWx5T8TfCgETJOVPUpNpSodF8U+cvIIpZM+DLiDc3Dyu6Zrod5guZ y989Sc+Be1LZEEyy0VscCoDleNxuFohh8aNJZnRtzd5UfJnz7cDIfGUdS2hwP9JN vI7Ci4nQIcvG35RwnLVMOp1azm3RIv2xoESdLkbS9/4smNEjLT1xtr6uVcP+MIKE qsWh8TITRWF4aiFqmsz1JyTHFAL0cCi4lZM//Y6XGKM2z0sCmpbfHIEGhJWuSNme lXvqn62VfiA5CvSnijYMwtRnCKIDDhsjvQo6H0gxCqW6ynCnKAivL/yo65hqtQO8 wBpmlziU7IXx4Js/1eGpF7zq7a9LHFqFnKCrE/+7hK/DPGF2Qck= =X5uk -----END PGP SIGNATURE----- Merge tag 'newsoc-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull RISC-V SoC updates from Arnd Bergmann: "Add support for StarFive JH7100 RISC-V SoC This adds support for the StarFive JH7100, including the necessary device drivers and DT files for the BeagleV Starlight prototype board, with additional boards to be added later.

riscv: dts: sifive unmatched: Fix regulator for board rev3
The existing values are rejected by the da9063 regulator driver, as they are unachievable with the declared chip setup (non-merged vcore and bmem are unable to provide the declared curent). Fix voltages to match rev3 schematics, which also matches their boot-up configuration within the chip's available precision. Declare bcore1/bcore2 and bmem/bio as merged. Set ldo09 and ldo10 as always-on as their consumers are not declared but exist. Drop ldo current limits as there is no current limit feature for these regulators in the DA9063.

riscv: dts: sifive unmatched: Expose the board ID eeprom
Mark it as read-only as it is factory-programmed with identifying information, and no executable nor configuration: - eth MAC address - board model (PCB version, BoM version) - board serial number Accidental modification would cause misidentification which could brick the board, so marking read-only seem like both a safe and non-constraining choice.

Basic StarFive JH7100 RISC-V SoC support
This adds support for the StarFive JH7100 RISC-V SoC. The SoC has many devices that need non-coherent DMA operations to work which isn't upstream yet[1], so this just adds basic support to boot up, get a serial console, blink an LED and reboot itself. Unlike the Allwinner D1 this chip doesn't use any extra pagetable bits, but instead the DDR RAM appears twice in the memory map, with and without the cache. The JH7100 is a test chip for the upcoming JH7110 and about 300 BeagleV Starlight Beta boards were sent out with them as part of a now cancelled BeagleBoard.org project. However StarFive has produced more of the JH7100s and will be selling VisionFive boards with them soon[2].

RISC-V Fixes for 5.16-rc2
I have two patches for 5.16: * A fix that allows external modules to be built against read-only source trees. * A patch to turn KVM on in the defconfigs. The second one isn't technically a fix, but it got tied up pending some defconfig cleanups that ended up finding some larger issues. I figured it'd be better to get the config changes some more testing, but didn't want to hold up turning KVM on for that. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmGXzdITHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYidHdEAC7kg6zRKtR3GCyvW9NVqPLucnRjxNz 8ubhqOu8kC4NByof5M7TYVExeCH4KDvIZ4T807wh951sK5ahO3eOMdwtId4gg7nS bHvbdbjo7nERL1eTNLkAr4lbD1iG2K4OwBD4OHOmTcB7BjJPbSucA//mBRd4j1VB u8GGYHwOjd5WkBz6BuwfEafd/CN32xCahROgwI+cS79rH/pTcw/dDW7YVkXZlAO4 DMszPHyDNMoPyC/0F+hhpV8rZ+A9+efhesuOKtlgVa1uk0a5Fiwarie7KsvOaI0Z mxOgq1d781Gd8rL7BMrpO+6yKBcixl2SpLXChVL/MYHowgw8WHwAVwE8NiemIKfT PnmtjpHTLzUvf38P95FW4pTgd00/goVbrjOzaHu33eqx2eLXOPjhBUF7Uiqjhs87 mlZbk8uy38cOvd4C2yM08O6rRPMKGyp4cyWuxaorXxQrLTR3/ESF9rkOZdXFefEN YzarzgAPNRqsa1eMx4nws1IL2EScFNEghdUkJWD6UkJo6XfyOqUf46z063QZQxUx E8cMLJ7M/IprQVVg5KoyyN3oorcuKBs7XeNUbw+CjCGgDTrmaoUgpUOTne08h13/ T6P6uTNOeFBH68Qr3bQp3jkZPv8CZeLEV+rXJ7xx9Q7DpfMynq7M8kArO2ZuweCg CiOufrqheNxTyQ== =EMf9 -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Palmer Dabbelt: "I have two patches for 5.16: - allow external modules to be built against read-only source trees - turn KVM on in the defconfigs The second one isn't technically a fix, but it got tied up pending some defconfig cleanups that ended up finding some larger issues.

Tracing updates for 5.16:
- kprobes: Restructured stack unwinder to show properly on x86 when a stack dump happens from a kretprobe callback. - Fix to bootconfig parsing - Have tracefs allow owner and group permissions by default (only denying others). There's been pressure to allow non root to tracefs in a controlled fashion, and using groups is probably the safest. - Bootconfig memory managament updates. - Bootconfig clean up to have the tools directory be less dependent on changes in the kernel tree. - Allow perf to be traced by function tracer. - Rewrite of function graph tracer to be a callback from the function tracer instead of having its own trampoline (this change will happen on an arch by arch basis, and currently only x86_64 implements it). - Allow multiple direct trampolines (bpf hooks to functions) be batched together in one synchronization. - Allow histogram triggers to add variables that can perform calculations against the event's fields. - Use the linker to determine architecture callbacks from the ftrace trampoline to allow for proper parameter prototypes and prevent warnings from the compiler. - Extend histogram triggers to key off of variables. - Have trace recursion use bit magic to determine preempt context over if branches. - Have trace recursion disable preemption as all use cases do anyway. - Added testing for verification of tracing utilities. - Various small clean ups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYYBdxhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qp1sAQD2oYFwaG3sx872gj/myBcHIBSKdiki Hry5csd8zYDBpgD+Poylopt5JIbeDuoYw/BedgEXmscZ8Qr7VzjAXdnv/Q4= =Loz8 -----END PGP SIGNATURE----- Merge tag 'trace-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - kprobes: Restructured stack unwinder to show properly on x86 when a stack dump happens from a kretprobe callback. - Fix to bootconfig parsing - Have tracefs allow owner and group permissions by default (only denying others).

cpu-to-thread_info update for v5.16-rc1
Cross-architecture update to move task_struct::cpu back into thread_info on arm64, x86, s390, powerpc, and riscv. All Acked by arch maintainers. Quoting Ard Biesheuvel: "Move task_struct::cpu back into thread_info Keeping CPU in task_struct is problematic for architectures that define raw_smp_processor_id() in terms of this field, as it requires linux/sched.h to be included, which causes a lot of pain in terms of circular dependencies (aka 'header soup') This series moves it back into thread_info (where it came from) for all architectures that enable THREAD_INFO_IN_TASK, addressing the header soup issue as well as some pointless differences in the implementations of task_cpu() and set_task_cpu()." -----BEGIN PGP SIGNATURE----- iQJKBAABCgA0FiEEpcP2jyKd1g9yPm4TiXL039xtwCYFAmGAEPYWHGtlZXNjb29r QGNocm9taXVtLm9yZwAKCRCJcvTf3G3AJq4wEACItgLuyzPgB2eSLVMc3sHPIWcn EUWbAWsuzJH79wmJtn2AKxW/C5OLBNGeoNjkXQvFN3ULkQDPrfCpB4x/tB6CjIQI WRDf8kO7oaAD85ZrbSwyFl/MFfrD67f6H1HZoB9FKWAzuv/Bp2xQ0Kf06Dv4HEZp CzprzZuWtjHB+qgyy+EpGOge3zbFmCuYPE2QpMYLWgs1rcVW9OYvoCI6AYtNefrC 6Kl6CbmBb1k6lFxkhM7wvRcIJthBl6Bajpc3Z2uL1aLb27dVpQZs3YpY859Knb6U ZpOQCRJOMui3HOxyF3bDUI37y0XVLm6xaNM6C/7i0XS1GiFlSxkGVamg+Mp7anpI +hdK5kqtSagaBC9CaJvRHnWIex1npQAfiyDNdyiEbrsUJ1dp6/zZcQSe4/m/XRbi vywQPGxU9f1ASshzHsGU2TJf7Ps7qHulUsS5fKwmHU2ZjQnbYCoPN10JGO9gKjOX yioN5xsKnbPY9j0ys3l9XBqaMJ8KAr1XspplTGIMZIVbjNMlqrfgbg8Qn8T8WGM7 oUqudMIxczilj0/iEGfGRxBeFaYAfhGQCDnxNlNX9g7Xe/gHTJgNYlHVxL55jHNu AoPE3Gd0X8K9fbov0BCB6a21XwGJ6Wj+FSrnvuyWrRuy8JWiDFJaVKUBEcalKr7a MhoUNQPu5M83OdC42A== =PzvV -----END PGP SIGNATURE----- Merge tag 'cpu-to-thread_info-v5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull thread_info update to move 'cpu' back from task_struct from Kees Cook: "Cross-architecture update to move task_struct::cpu back into thread_info on arm64, x86, s390, powerpc, and riscv.

Scheduler updates:
- Revert the printk format based wchan() symbol resolution as it can leak the raw value in case that the symbol is not resolvable. - Make wchan() more robust and work with all kind of unwinders by enforcing that the task stays blocked while unwinding is in progress. - Prevent sched_fork() from accessing an invalid sched_task_group - Improve asymmetric packing logic - Extend scheduler statistics to RT and DL scheduling classes and add statistics for bandwith burst to the SCHED_FAIR class. - Properly account SCHED_IDLE entities - Prevent a potential deadlock when initial priority is assigned to a newly created kthread. A recent change to plug a race between cpuset and __sched_setscheduler() introduced a new lock dependency which is now triggered. Break the lock dependency chain by moving the priority assignment to the thread function. - Fix the idle time reporting in /proc/uptime for NOHZ enabled systems. - Improve idle balancing in general and especially for NOHZ enabled systems. - Provide proper interfaces for live patching so it does not have to fiddle with scheduler internals. - Add cluster aware scheduling support. - A small set of tweaks for RT (irqwork, wait_task_inactive(), various scheduler options and delaying mmdrop) - The usual small tweaks and improvements all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmF/OUkTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoR/5D/9ikdGNpKg9osNqJ3GjAmxsK6kVkB29 iFe2k8pIpWDToWQf/wQRGih4Yj3Cl49QSnZcPIibh2/12EB1qrrW6iSPJkInz8Ec /1LS5/Vewn2OyoxyXZjdvGC5gTXEodSbIazASvX7nvdMeI4gsAsL5etzrMJirT/t aymqvr7zovvywrwMTQJrGjUMo9l4ewE8tafMNNhRu1BHU1U4ojM9yvThyRAAcmp7 3Xy49A+Yq3IgrvYI4u8FMK5Zh08KaxSFjiLhePGm/bF+wSfYmWop2TP1jY05W2Uo ti8hfbJMUoFRYuMxAiEldkItnc0wV4M9PtWZZ/x+B71bs65Y4Zjt9cW+rxJv2+m1 vzV31EsQwGnOti072dzWN4c/cZqngVXAjaNtErvDwJUr+Tw1ayv9KUvuodMQqZY6 mu68bFUO2kV9EMe1CBOv51Uy1RGHyLj3rlNqrkw+Xp5ISE9Ad2vhUEiRp5bQx5Ci V/XFhGZkGUluh0vccrdFlNYZwhj8cZEzkOPCnPSeZ+bq8SyZE6xuHH/lTP1CJCOy s800rW1huM+kgV+zRN8adDkGXibAk9N3RtVGnQXmuEy8gB9LZmQg+JeM2wsc9B+6 i0gdqZnsjNAfoK+BBAG4holxptSL8/eOJsFH8ZNIoxQ+iqooyPx9tFX7yXnRTBQj d2qWG7UvoseT+g== =fgtS -----END PGP SIGNATURE----- Merge tag 'sched-core-2021-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Thomas Gleixner: - Revert the printk format based wchan() symbol resolution as it can leak the raw value in case that the symbol is not resolvable. - Make wchan() more robust and work with all kind of unwinders by enforcing that the task stays blocked while unwinding is in progress. - Prevent sched_fork() from accessing an invalid sched_task_group - Improve asymmetric packing logic - Extend scheduler statistics to RT and DL scheduling classes and add statistics for bandwith burst to the SCHED_FAIR class. - Properly account SCHED_IDLE entities - Prevent a potential deadlock when initial priority is assigned to a newly created kthread.

riscv, bpf: Increase the maximum number of iterations
Now that BPF programs can be up to 1M instructions, it is not uncommon that a program requires more than the current 16 iterations to converge. Bump it to 32, which is enough for selftests/bpf, and test_bpf.ko.
