[PATCH v3 0/3] rust: kunit: Support KUnit tests with a user-space like syntax

by David Gow

This series was originally written by José Expósito, and has been modified and updated by Matt Gilbride and myself. The original version can be found here: https://github.com/Rust-for-Linux/linux/pull/950 Add support for writing KUnit tests in Rust. While Rust doctests are already converted to KUnit tests and run, they're really better suited for examples, rather than as first-class unit tests. This series implements a series of direct Rust bindings for KUnit tests, as well as a new macro which allows KUnit tests to be written using a close variant of normal Rust unit test syntax. The only change required is replacing '#[cfg(test)]' with '#[kunit_tests(kunit_test_suite_name)]' An example test would look like: #[kunit_tests(rust_kernel_hid_driver)] mod tests { use super::*; use crate::{c_str, driver, hid, prelude::*}; use core::ptr; struct SimpleTestDriver; impl Driver for SimpleTestDriver { type Data = (); } #[test] fn rust_test_hid_driver_adapter() { let mut hid = bindings::hid_driver::default(); let name = c_str!("SimpleTestDriver"); static MODULE: ThisModule = unsafe { ThisModule::from_ptr(ptr::null_mut()) }; let res = unsafe { <hid::Adapter<SimpleTestDriver> as driver::DriverOps>::register(&mut hid, name, &MODULE) }; assert_eq!(res, Err(ENODEV)); // The mock returns -19 } } Please give this a go, and make sure I haven't broken it! There's almost certainly a lot of improvements which can be made -- and there's a fair case to be made for replacing some of this with generated C code which can use the C macros -- but this is hopefully an adequate implementation for now, and the interface can (with luck) remain the same even if the implementation changes. A few small notable missing features: - Attributes (like the speed of a test) are hardcoded to the default value. - Similarly, the module name attribute is hardcoded to NULL. In C, we use the KBUILD_MODNAME macro, but I couldn't find a way to use this from Rust which wasn't more ugly than just disabling it. - Assertions are not automatically rewritten to use KUnit assertions. --- Changes since v2: https://lore.kernel.org/linux-kselftest/20241029092422.2884505-1-davidgow@g… - Include missing rust/macros/kunit.rs file from v2. (Thanks Boqun!) - The kunit_unsafe_test_suite!() macro will truncate the name of the suite if it is too long. (Thanks Alice!) - The proc macro now emits an error if the suite name is too long. - We no longer needlessly use UnsafeCell<> in kunit_unsafe_test_suite!(). (Thanks Alice!) Changes since v1: https://lore.kernel.org/lkml/20230720-rustbind-v1-0-c80db349e3b5@google.com… - Rebase on top of the latest rust-next (commit 718c4069896c) - Make kunit_case a const fn, rather than a macro (Thanks Boqun) - As a result, the null terminator is now created with kernel::kunit::kunit_case_null() - Use the C kunit_get_current_test() function to implement in_kunit_test(), rather than re-implementing it (less efficiently) ourselves. Changes since the GitHub PR: - Rebased on top of kselftest/kunit - Add const_mut_refs feature This may conflict with https://lore.kernel.org/lkml/20230503090708.2524310-6-nmi@metaspace.dk/ - Add rust/macros/kunit.rs to the KUnit MAINTAINERS entry --- José Expósito (3): rust: kunit: add KUnit case and suite macros rust: macros: add macro to easily run KUnit tests rust: kunit: allow to know if we are in a test MAINTAINERS | 1 + rust/kernel/kunit.rs | 191 +++++++++++++++++++++++++++++++++++++++++++ rust/kernel/lib.rs | 1 + rust/macros/kunit.rs | 153 ++++++++++++++++++++++++++++++++++ rust/macros/lib.rs | 29 +++++++ 5 files changed, 375 insertions(+) create mode 100644 rust/macros/kunit.rs -- 2.47.0.163.g1226f6d8fa-goog

[PATCH net-next v8 00/24] Introducing OpenVPN Data Channel Offload

by Antonio Quartulli

This is the 8th version of the ovpn patchset. Thanks Sergey for arguing regarding splitting PEER_SET into SET and NEW. I decided to follow this suggestion as it makes the API and its return value easier to work with. Thanks Donald for the suggestions regarding the NL API - they have all been implemented (unless I forgot some, but hopefully I did not). Notable changes from v7: * Netlink API adjustments: ** renamed NL API from OP_OBJ to OBJ_OP (i.e. from SET_PEER to PEER_SET) ** split PEER_SET from PEER_NEW for better clarity in case of error ** renamed NL API from NEW/DEL_IFACE to DEV_NEW/DEL ** converted all underscores to dashes in YML NL spec ** split sockaddr_remote attr into ipv4/6, port and v6_scope_id attrs ** split local_ip attr into local_ipv4 and local_ipv6 attrs ** turned keyconf into a root attribute (it was nested in peer before) ** made key_swap use a keyconf object rather than a peer for consistency with key mgmt API ** created specific op for peer_del notification (peer_del_ntf) ** created specific op for key_swap notification (key_swap_ntf) ** allow user to update VPN IPv4/6 (peer is now rehashable) ** converted port attrs from u32 to u16 for better consistency with userspace code * added rtnl_ops .dellink implementation * removed patch 2 as it's not needed anymore thanks to the point above * moved rtnl_ops .kind initialization to first patch * updated MAINTAINERS file with Github tree and selftest folder * wrapped long lines in selftest scripts BONUS: used b4 for the first time to prepare the patchset and send it Please note that patches previously reviewed by Andrew Lunn have retained the Reviewed-by tag as they have been simply rebased without any modification.

[PATCH v4 0/3] bpf: Using binary search to improve the performance of btf_find_by_name_kind

by Donglin Peng

Currently, we are only using the linear search method to find the type id by the name, which has a time complexity of O(n). This change involves sorting the names of btf types in ascending order and using binary search, which has a time complexity of O(log(n)). This idea was inspired by the following patch: 60443c88f3a8 ("kallsyms: Improve the performance of kallsyms_lookup_name()"). At present, this improvement is only for searching in vmlinux's and module's BTFs. Another change is the search direction, where we search the BTF first and then its base, the type id of the first matched btf_type will be returned. Here is a time-consuming result that finding 87590 type ids by their names in vmlinux's BTF. Before: 158426 ms After: 114 ms The average lookup performance has improved more than 1000x in the above scenario. v4: - Divide the patch into two parts: kernel and libbpf - Use Eduard's code to sort btf_types in the btf__dedup function - Correct some btf testcases due to modifications of the order of btf_types. v3: - Link: https://lore.kernel.org/all/20240608140835.965949-1-dolinux.peng@gmail.com/ - Sort btf_types during build process other than during boot, to reduce the overhead of memory and boot time. v2: - Link: https://lore.kernel.org/all/20230909091646.420163-1-pengdonglin@sangfor.com… Donglin Peng (3): libbpf: Sort btf_types in ascending order by name bpf: Using binary search to improve the performance of btf_find_by_name_kind libbpf: Using binary search to improve the performance of btf__find_by_name_kind include/linux/btf.h | 1 + kernel/bpf/btf.c | 157 +++++++++- tools/lib/bpf/btf.c | 274 +++++++++++++--- tools/testing/selftests/bpf/prog_tests/btf.c | 296 +++++++++--------- .../bpf/prog_tests/btf_dedup_split.c | 64 ++-- 5 files changed, 555 insertions(+), 237 deletions(-) -- 2.34.1

[PATCH v3 0/4] vfio-pci support pasid attach/detach

by Yi Liu

This adds the pasid attach/detach uAPIs for userspace to attach/detach a PASID of a device to/from a given ioas/hwpt. Only vfio-pci driver is enabled in this series. After this series, PASID-capable devices bound with vfio-pci can report PASID capability to userspace and VM to enable PASID usages like Shared Virtual Addressing (SVA). Based on the discussion about reporting the vPASID to VM [1], it's agreed that we will let the userspace VMM to synthesize the vPASID capability. The VMM needs to figure out a hole to put the vPASID cap. This includes the hidden bits handling for some devices. While, it's up to the userspace, it's not the focus of this series. This series first adds the helpers for pasid attach in vfio core and then adds the device cdev ioctls for pasid attach/detach. In the end of this series, the IOMMU_GET_HW_INFO ioctl is extended to report the PCI PASID capability to the userspace. Userspace should check this before using any PASID related uAPIs provided by VFIO, which is the agreement in [2]. This series depends on the iommufd pasid attach/detach series [3]. The completed code can be found at [4], tested with a hacky Qemu branch [5].
