2025-05-19kunit: tool: add test counts to JSON outputRae Moar
Add the test counts to the JSON output from kunit.py. For example: ... "git_branch": "kselftest", "misc": { "tests": 2, "passed": 1. "failed": 1, "crashed": 0, "skipped": 0, "errors": 0, } ... To output the JSON using the following command: ./tools/testing/kunit/kunit.py run example --json This has been requested by KUnit users. The counts are in a "misc" field because the JSON output needs to be compliant with the KCIDB submission guide. There are no counts fields but there is a "misc" field in the guide.

The 32-bit sparc configuration (--arch sparc) crashes on the kunit_fault_test. It's known that some architectures don't handle deliberate segfaults in kernel mode well, so there's a config switch to disable tests which rely upon it by default.

2025-04-15kunit: tool: Implement listing of available architecturesThomas Weißschuh
To implement custom scripting around kunit.py it is useful to get a list of available architectures. While it is possible to manually inspect tools/testing/kunit/qemu_configs/, this is annoying to implement and introduces a dependency on a kunit.py implementation detail. Introduce 'kunit.py run --arch help' which lists all known architectures in an easy to parse list. This is equivalent on how QEMU implements listing of possible argument values.

2025-03-26landlock: Add unique ID generatorMickaël Salaün
Landlock IDs can be generated to uniquely identify Landlock objects. For now, only Landlock domains get an ID at creation time. These IDs map to immutable domain hierarchies. Landlock IDs have important properties: - They are unique during the lifetime of the running system thanks to the 64-bit values: at worse, 2^60 - 2*2^32 useful IDs. - They are always greater than 2^32 and must then be stored in 64-bit integer types. - The initial ID (at boot time) is randomly picked between 2^32 and 2^33, which limits collisions in logs across different boots. - IDs are sequential, which enables users to order them. - IDs may not be consecutive but increase with a random 2^4 step, which limits side channels. Such IDs can be exposed to unprivileged processes, even if it is not the case with this audit patch series. The domain IDs will be useful for user space to identify sandboxes and get their properties. These Landlock IDs are more secure that other absolute kernel IDs such as pipe's inodes which rely on a shared global counter. For checkpoint/restore features (i.e. CRIU), we could easily implement a privileged interface (e.g. sysfs) to set the next ID counter. IDR/IDA are not used because we only need a bijection from Landlock objects to Landlock IDs, and we must not recycle IDs. This enables us to identify all Landlock objects during the lifetime of the system (e.g. in logs), but not to access an object from an ID nor know if an ID is assigned. Using a counter is simpler, it scales (i.e. avoids growing memory footprint), and it does not require locking. We'll use proper file descriptors (with IDs used as inode numbers) to access Landlock objects.

2025-02-18kunit: tool: Build GDB scriptsBrendan Jackman
Following a similar rationale as commit e4835f1da425f ("kunit: tool: Build compile_commands.json"), make a common developer tool available by default for KUnit users. Compared to compile_commands.json, there is a little more work to be done to build the GDB scripts. Is it enough to affect development cycle duration? Unscientific evaluation: rm -rf .kunit; time tools/testing/kunit/kunit.py build --kunitconfig ./lib/kunit/.kunitconfig --jobs 96 Without this patch it took 14.77s, with this patch it took 14.83. So, although `make scripts_gdb` is pretty slow, presumably most of that is just the overhead of running Kbuild at all, actually building the scripts is approximately free. Note also, to actually get the GDB scripts the user needs to enable CONFIG_SCRIPTS_GDB, but building the scripts_gdb target without that is still harmless.

2025-02-15kunit: qemu_configs: sparc: use Zilog consoleThomas Weißschuh
The driver for the 8250 console is not used, as no port is found. Instead the prom0 bootconsole is used the whole time. The prom driver translates '\n' to '\r\n' before handing of the message off to the firmware. The firmware performs the same translation again. In the final output produced by QEMU each line ends with '\r\r\n'. This breaks the kunit parser, which can only handle '\r\n' and '\n'. Use the Zilog console instead. It works correctly, is the one documented by the QEMU manual and also saves a bit of codesize: Before=4051011, After=4023326, chg -0.68% Observed on QEMU 9.2.0.

compile_commands.json is used by clangd[1] to provide code navigation and completion functionality to editors. See [2] for an example configuration that includes this functionality for VSCode. It can currently be built manually when using kunit.py, by running: ./scripts/clang-tools/gen_compile_commands.py -d .kunit With this change however, it's built automatically so you don't need to manually keep it up to date. Unlike the manual approach, having make build the compile_commands.json means that it appears in the build output tree instead of at the root of the source tree, so you'll need to add --compile-commands-dir=.kunit to your clangd args for it to be found. This might turn out to be pretty annoying, I'm not sure yet. If so maybe we can later add some hackery to kunit.py to work around it.

https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers RISC-V SoC Kconfig Updates for v6.10 A few different bits of SoC-related Kconfig work. The first part of this is shared with the DT updates - the modification of all SOC_CANAAN users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away from the k230 that is able to be used in a "common" kernel. The other thing here is the removal of most of the SOC_VENDOR options, with their ARCH_VENDOR equivalents that've been waiting in the wings for 1 year+ now made visible. Due a lapse on my part when originally adding the ARCH_VENDOR stuff, the Microchip transition isn't complete - the _POLARFIRE was a mistake to keep as there's gonna be non-PolarFire RISC-V stuff from Microchip soonTM.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis. Poll length and budget parameters can be set independently of system defaults. - Introduce struct net_hotdata, to make sure read-mostly global config variables fit in as few cache lines as possible. - Add optional per-nexthop statistics to ease monitoring / debug of ECMP imbalance problems. - Support TCP_NOTSENT_LOWAT in MPTCP. - Ensure that IPv6 temporary addresses' preferred lifetimes are long enough, compared to other configured lifetimes, and at least 2 sec. - Support forwarding of ICMP Error messages in IPSec, per RFC 4301. - Add support for the independent control state machine for bonding per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled control state machine. - Add "network ID" to MCTP socket APIs to support hosts with multiple disjoint MCTP networks. - Re-use the mono_delivery_time skbuff bit for packets which user space wants to be sent at a specified time. Maintain the timing information while traversing veth links, bridge etc. - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets. - Simplify many places iterating over netdevs by using an xarray instead of a hash table walk (hash table remains in place, for use on fastpaths). - Speed up scanning for expired routes by keeping a dedicated list. - Speed up "generic" XDP by trying harder to avoid large allocations. - Support attaching arbitrary metadata to netconsole messages. Things we sprinkled into general kernel code: - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena). - Rework selftest harness to enable the use of the full range of ksft exit code (pass, fail, skip, xfail, xpass). Netfilter: - Allow userspace to define a table that is exclusively owned by a daemon (via netlink socket aliveness) without auto-removing this table when the userspace program exits. Such table gets marked as orphaned and a restarting management daemon can re-attach/regain ownership. - Speed up element insertions to nftables' concatenated-ranges set type. Compact a few related data structures. BPF: - Add BPF token support for delegating a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. - Introduce bpf_arena which is sparse shared memory region between BPF program and user space where structures inside the arena can have pointers to other areas of the arena, and pointers work seamlessly for both user-space programs and BPF programs. - Introduce may_goto instruction that is a contract between the verifier and the program. The verifier allows the program to loop assuming it's behaving well, but reserves the right to terminate it. - Extend the BPF verifier to enable static subprog calls in spin lock critical sections. - Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type. - Add support for retrieval of cookies for perf/kprobe multi links. - Support arbitrary TCP SYN cookie generation / validation in the TC layer with BPF to allow creating SYN flood handling in BPF firewalls. - Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects. Wireless: - Add SPP (signaling and payload protected) AMSDU support. - Support wider bandwidth OFDMA, as required for EHT operation. Driver API: - Major overhaul of the Energy Efficient Ethernet internals to support new link modes (2.5GE, 5GE), share more code between drivers (especially those using phylib), and encourage more uniform behavior. Convert and clean up drivers. - Define an API for querying per netdev queue statistics from drivers. - IPSec: account in global stats for fully offloaded sessions. - Create a concept of Ethernet PHY Packages at the Device Tree level, to allow parameterizing the existing PHY package code. - Enable Rx hashing (RSS) on GTP protocol fields. Misc: - Improvements and refactoring all over networking selftests. - Create uniform module aliases for TC classifiers, actions, and packet schedulers to simplify creating modprobe policies. - Address all missing MODULE_DESCRIPTION() warnings in networking. - Extend the Netlink descriptions in YAML to cover message encapsulation or "Netlink polymorphism", where interpretation of nested attributes depends on link type, classifier type or some other "class type".

Add the SECURITY_LANDLOCK_KUNIT_TEST option to enable KUnit tests for Landlock. The minimal required configuration is listed in the security/landlock/.kunitconfig file. Add an initial landlock_fs KUnit test suite with 7 test cases for filesystem helpers. These are related to the LANDLOCK_ACCESS_FS_REFER right. There is one KUnit test case per: * mutated state (e.g. test_scope_to_request_*) or, * shared state between tests (e.g. test_is_eaccess_*). Add macros to improve readability of tests (i.e. one per line). Test cases are collocated with the tested functions to help maintenance and improve documentation. This is why SECURITY_LANDLOCK_KUNIT_TEST cannot be set as module. This is a nice complement to Landlock's user space kselftests. We expect new Landlock features to come with KUnit tests as well.

2023-07-26kunit: tool: Add command line interface to filter and report attributesRae Moar
Add ability to kunit.py to filter attributes and report a list of tests including attributes without running tests. Add flag "--filter" to input filters on test attributes. Tests will be filtered out if they do not match all inputted filters. Example: --filter speed=slow (This filter would run only the tests that are marked as slow) Filters have operations: <, >, <=, >=, !=, and =. But note that the characters < and > are often interpreted by the shell, so they may need to be quoted or escaped. Example: --filter "speed>slow" or --filter speed\>slow (This filter would run only the tests that have the speed faster than slow. Additionally, multiple filters can be used. Example: --filter "speed=slow, module!=example" (This filter would run only the tests that have the speed slow and are not in the "example" module) Note if the user wants to skip filtered tests instead of not running/showing them use the "--filter_action=skip" flag instead. Expose the output of kunit.action=list option with flag "--list_tests" to output a list of tests. Additionally, add flag "--list_tests_attr" to output a list of tests and their attributes. These flags are useful to see tests and test attributes without needing to run tests. Example of the output of "--list_tests_attr": example example.test_1 example.test_2 # example.test_2.speed: slow This output includes a suite, example, with two test cases, test_1 and test_2. And in this instance test_2 has been marked as slow. Reviewed-by: David Gow <davidgow@google.com> Signed-off-by: Rae Moar <rmoar@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
