[PATCH RFC v2 0/5] Verify bias functionality for pinctrl_paris driver through new gpio test

by Nícolas F. R. A. Prado

This series was motivated by the regression fixed by 166bf8af9122 ("pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPE"). A bug was introduced in the pinctrl_paris driver which prevented certain pins from having their bias configured. Running this test on the mt8195-tomato platform with the test plan included below[1] shows the test passing with the fix applied, but failing without the fix: With fix: $ ./gpio-setget-config.py TAP version 13 # Using test plan file: ./google,tomato.yaml 1..3 ok 1 pinctrl_paris.34.pull-up ok 2 pinctrl_paris.34.pull-down ok 3 pinctrl_paris.34.disabled # Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Without fix: $ ./gpio-setget-config.py TAP version 13 # Using test plan file: ./google,tomato.yaml 1..3 # Bias doesn't match: Expected pull-up, read pull-down. not ok 1 pinctrl_paris.34.pull-up ok 2 pinctrl_paris.34.pull-down # Bias doesn't match: Expected disabled, read pull-down. not ok 3 pinctrl_paris.34.disabled # Totals: pass:1 fail:2 xfail:0 xpass:0 skip:0 error:0 In order to achieve this, the first three patches expose bias configuration through the GPIO API in the MediaTek pinctrl drivers, notably, pinctrl_paris, patch 4 extends the gpio-mockup-cdev utility for use by patch 5, and patch 5 introduces a new GPIO kselftest that takes a test plan in YAML, which can be tailored per-platform to specify the configurations to test, and sets and gets back each pin configuration to verify that they match and thus that the driver is behaving as expected. Since the GPIO uAPI only allows setting the pin configuration, getting it back is done through pinconf-pins in the pinctrl debugfs folder. The test currently only verifies bias but it would be easy to extend to verify other pin configurations. The test plan YAML file can be customized for each use-case and is platform-dependant. For that reason, only an example is included in patch 3 and the user is supposed to provide their test plan. That said, the aim is to collect test plans for ease of use at [2]. [1] This is the test plan used for mt8195-tomato: - label: "pinctrl_paris" tests: # Pin 34 has type MTK_PULL_PU_PD_RSEL_TYPE and is unused. # Setting bias to MTK_PULL_PU_PD_RSEL_TYPE pins was fixed by # 166bf8af9122 ("pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPE") - pin: 34 bias: "pull-up" - pin: 34 bias: "pull-down" - pin: 34 bias: "disabled" [2] https://github.com/kernelci/platform-test-parameters Signed-off-by: Nícolas F.

[PATCH v4] net: ipv4: Cache pmtu for all packet paths if multipath enabled

by Vladimir Vdovin

Check number of paths by fib_info_num_path(), and update_or_create_fnhe() for every path. Problem is that pmtu is cached only for the oif that has received icmp message "need to frag", other oifs will still try to use "default" iface mtu. V4: - fix selftest, do route lookup before checking cached exceptions V3: - added selftest - fixed compile error V2: - fix fib_info_num_path parameter pass An example topology showing the problem: | host1 +---------+ | dummy0 | 10.179.20.18/32 mtu9000 +---------+ +-----------+----------------+ +---------+ +---------+ | ens17f0 | 10.179.2.141/31 | ens17f1 | 10.179.2.13/31 +---------+ +---------+ | (all here have mtu 9000) | +------+ +------+ | ro1 | 10.179.2.140/31 | ro2 | 10.179.2.12/31 +------+ +------+ | | ---------+------------+-------------------+------ | +-----+ | ro3 | 10.10.10.10 mtu1500 +-----+ | ======================================== some networks ======================================== | +-----+ | eth0| 10.10.30.30 mtu9000 +-----+ | host2 host1 have enabled multipath and sysctl net.ipv4.fib_multipath_hash_policy = 1: default proto static src 10.179.20.18 nexthop via 10.179.2.12 dev ens17f1 weight 1 nexthop via 10.179.2.140 dev ens17f0 weight 1 When host1 tries to do pmtud from 10.179.20.18/32 to host2, host1 receives at ens17f1 iface an icmp packet from ro3 that ro3 mtu=1500. And host1 caches it in nexthop exceptions cache. Problem is that it is cached only for the iface that has received icmp, and there is no way that ro3 will send icmp msg to host1 via another path. Host1 now have this routes to host2: ip r g 10.10.30.30 sport 30000 dport 443 10.10.30.30 via 10.179.2.12 dev ens17f1 src 10.179.20.18 uid 0 cache expires 521sec mtu 1500 ip r g 10.10.30.30 sport 30033 dport 443 10.10.30.30 via 10.179.2.140 dev ens17f0 src 10.179.20.18 uid 0 cache So when host1 tries again to reach host2 with mtu>1500, if packet flow is lucky enough to be hashed with oif=ens17f1 its ok, if oif=ens17f0 it blackholes and still gets icmp msgs from ro3 to ens17f1, until lucky day when ro3 will send it through another flow to ens17f0.

[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 net-next v6 00/12] selftests: ncdevmem: Add ncdevmem to ksft

by Stanislav Fomichev

The goal of the series is to simplify and make it possible to use ncdevmem in an automated way from the ksft python wrapper. ncdevmem is slowly mutated into a state where it uses stdout to print the payload and the python wrapper is added to make sure the arrived payload matches the expected one. v6: - fix compilation issue in 'Unify error handling' patch (Jakub) v5: - properly handle errors from inet_pton() and socket() (Paolo) - remove unneeded import from python selftest (Paolo) v4: - keep usage example with validation (Mina) - fix compilation issue in one patch (s/start_queues/start_queue/) v3: - keep and refine the comment about ncdevmem invocation (Mina) - add the comment about not enforcing exit status for ntuple reset (Mina) - make configure_headersplit more robust (Mina) - use num_queues/2 in selftest and let the users override it (Mina) - remove memory_provider.memcpy_to_device (Mina) - keep ksft as is (don't use -v validate flags): we are gonna need a --debug-disable flag to make it less chatty; otherwise it times out when sending too much data; so leaving it as a separate follow up v2: - don't remove validation (Mina) - keep 5-tuple flow steering but use it only when -c is provided (Mina) - remove separate flag for probing (Mina) - move ncdevmem under drivers/net/hw, not drivers/net (Jakub) Cc: Mina Almasry <almasrymina(a)google.com> Stanislav Fomichev (12): selftests: ncdevmem: Redirect all non-payload output to stderr selftests: ncdevmem: Separate out dmabuf provider selftests: ncdevmem: Unify error handling selftests: ncdevmem: Make client_ip optional selftests: ncdevmem: Remove default arguments selftests: ncdevmem: Switch to AF_INET6 selftests: ncdevmem: Properly reset flow steering selftests: ncdevmem: Use YNL to enable TCP header split selftests: ncdevmem: Remove hard-coded queue numbers selftests: ncdevmem: Run selftest when none of the -s or -c has been provided selftests: ncdevmem: Move ncdevmem under drivers/net/hw selftests: ncdevmem: Add automated test .../selftests/drivers/net/hw/.gitignore | 1 + .../testing/selftests/drivers/net/hw/Makefile | 9 + .../selftests/drivers/net/hw/devmem.py | 45 + .../selftests/drivers/net/hw/ncdevmem.c | 773 ++++++++++++++++++ tools/testing/selftests/net/.gitignore | 1 - tools/testing/selftests/net/Makefile | 8 - tools/testing/selftests/net/ncdevmem.c | 570 ------------- 7 files changed, 828 insertions(+), 579 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/hw/.gitignore create mode 100755 tools/testing/selftests/drivers/net/hw/devmem.py create mode 100644 tools/testing/selftests/drivers/net/hw/ncdevmem.c delete mode 100644 tools/testing/selftests/net/ncdevmem.c -- 2.47.0
