* treewide: use get_random_u32() when possibleJason A. Donenfeld2022-10-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As there will be more USB4 devices that support NVM firmware upgrade from various vendors, it makes sense to split out the Intel specific NVM image handling from the generic code. This moves the Intel specific NVM handling into a new structure that will be matched by the device type and the vendor ID. Do this for both routers and retimers. This makes it easier to extend the NVM support to cover new vendors and NVM image formats in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel pre-USB4 host routers required the firmware connection manager to be active in order to perform NVM firmware upgrade and for this reason it was disabled when software connection manager is active. However, this is not necessary for USB4 host routers as this functionality is part of router operations that the router implements if it wants to support this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB4 spec defines standard set of registers to be used for receiver lane margining. This is useful for I/O interface quality and electrical robustness validation during manufacturing. Expose receiver lane margining through new debugfs directory "margining" that is added under each connected USB4 port. Users can then run the margining by writing to the exposed attributes under that directory. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF: - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols: - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API: - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys.

Accordingly, the parent field can be dropped from struct acpi_device and for this purpose define acpi_dev_parent() to retrieve a parent struct acpi_device pointer from the dev.parent field in struct acpi_device. Next, update all of the users of the parent field in struct acpi_device to use acpi_dev_parent() instead of it and drop it. While at it, drop the ACPI_IS_ROOT_DEVICE() macro that is only used in one place in a confusing way. No intentional functional impact. Signed-off-by: Rafael J.

We enable it, if both sides of the link support it, and only for the first hop router (i.e. the first device that connected to the host router). This is needed for better thermal management.

| * thunderbolt: Change downstream router's TMU rate in both TMU uni/bidir modeGil Fine2022-06-061-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of uni-directional time sync, TMU handshake is initiated by upstream router. In case of bi-directional time sync, TMU handshake is initiated by downstream router. In order to handle correctly the case of uni-directional mode, we avoid changing the upstream router's rate to off, because it might have another downstream router plugged that is set to uni-directional mode (and we don't want to change its mode). Instead, we always change downstream router's rate. Signed-off-by: Gil Fine <gil.fine@intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

| | | | | | | | | | | | | | | | | | We can't enable CLx if it is not supported either by the host or device, or by the USB4/TBT link (e.g. when an optical cable is used). We silently ignore CLx enabling in this case. Signed-off-by: Gil Fine <gil.fine@intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

Running tests on a production system could leave the system in a bad state. Summary: - Add a new taint type, TAINT_TEST to signal that a test has been run. This should discourage people from running these tests on production systems, and to make it easier to tell if tests have been run accidentally (by loading the wrong configuration, etc) - Several documentation and tool enhancements and fixes" * tag 'linux-kselftest-kunit-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (29 commits) Documentation: KUnit: Fix example with compilation error Documentation: kunit: Add CLI args for kunit_tool kcsan: test: Add a .kunitconfig to run KCSAN tests kunit: executor: Fix a memory leak on failure in kunit_filter_tests clk: explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in .kunitconfig mmc: sdhci-of-aspeed: test: Use kunit_test_suite() macro nitro_enclaves: test: Use kunit_test_suite() macro thunderbolt: test: Use kunit_test_suite() macro kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites kunit: unify module and builtin suite definitions selftest: Taint kernel when test module loaded module: panic: Taint the kernel when selftest modules load Documentation: kunit: fix example run_kunit func to allow spaces in args Documentation: kunit: Cleanup run_wrapper, fix x-ref kunit: test.h: fix a kernel-doc markup kunit: tool: Enable virtio/PCI by default on UML kunit: tool: make --kunitconfig repeatable, blindly concat kunit: add coverage_uml.config to enable GCOV on UML kunit: tool: refactor internal kconfig handling, allow overriding kunit: tool: introduce --qemu_args ...

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new implementation of kunit_test_suite() for modules no longer conflicts with module_init, so can now be used by the thunderbolt tests. Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is enabled. This means that kunit_tool can now successfully run and parse the test results with, for example: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \ 'thunderbolt' Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Daniel Latypov <dlatypov@google.com> Acked-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
