[PATCH] tools headers UAPI: remove stale lirc.h

by Sean Young

The lirc.h file is an old copy of lirc.h from the kernel sources. It is out of date, and the bpf lirc tests don't need a new copy anyway. As long as /usr/include/linux/lirc.h is from kernel v5.2 or newer, the tests will compile fine.

[PATCH v2] selftests: rtc: Increase test timeout so that all tests run

by Nícolas F. R. A. Prado

The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH] selftests: cpufreq: Write test output to stdout as well

by Nícolas F. R. A. Prado

Use 'tee' to send the test output to stdout in addition to the current output file. This makes the output easier to handle in automated test systems and is superior to only later dumping the output file contents to stdout, since this way the test output can be interleaved with other log messages, like from the kernel, so that chronology is preserved, making it easier to detect issues.

[PATCH v2] kselftest: signal all child processes

by Li Zhijian

We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process. In such case, if child process doesn't terminate itself, ksefltest framework will hang forever. below ps tree show the situation when ksefltest is blocking: root 1172 0.0 0.0 5996 2500 ?

[PATCH v8 00/38] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - SME is currently not supported for KVM guests, this will be done as a followup series. A host system can use SME and run KVM guests but SME is not available in the guests. - The KVM host support is done in a very simplistic way, were anyone to attempt to use it in production there would be performance impacts on hosts with SME support. As part of this we also add enumeration of fine grained traps. - There is not currently ptrace or signal support TPIDR2, this will be done as a followup series. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. v8: - Rebase onto v5.17-rc1. - Support interoperation with KVM, SME is disabled for KVM guests with minimal handling for cleaning up SME state when entering and leaving the guest. - Document and implement that signal handlers are invoked with ZA and streaming mode disabled. - Use the RDSVL instruction introduced in EAC2 of the architecture to obtain the streaming mode vector length during enumeration, ZA state loading/saving and in test programs. - Store a pointer to SVCR in fpsimd_last_state and use it in fpsimd_save() for interoperation with KVM. - Add a test case sme_trap_no_sm checking that we generate a SIGILL when using an instruction that requires streaming mode without enabling it. - Add basic ZA context form validation to testcases helper library. - Move signal tests over to validating streaming VL from ZA information. - Pulled in patch removing ARRAY_SIZE() so that kselftest builds cleanly and to avoid trivial conflicts. v7: - Rebase onto v5.16-rc3. - Reduce indentation when supporting custom triggers for signal tests as suggested by Catalin. - Change to specifying a width for all CPU features rather than adding single bit specific infrastructure. - Don't require zeroing of non-shared SVE state during syscalls. v6: - Rebase onto v5.16-rc1. - Return to disabling TIF_SVE on kernel entry even if we have SME state, this avoids the need for KVM to handle the case where TIF_SVE is set on guest entry. - Add syscall-abi.h to SME updates to syscall-abi, mistakenly omitted from commit. v5: - Rebase onto currently merged SVE and kselftest patches. - Add support for the FA64 option, introduced in the recently published EAC1 update to the specification. - Pull in test program for the syscall ABI previously sent separately with some revisions and add coverage for the SME ABI. - Fix checking for options with 1 bit fields in ID_AA64SMFR0_EL1. - Minor fixes and clarifications to the ABI documentation. v4: - Rebase onto merged patches. - Remove an uneeded NULL check in vec_proc_do_default_vl(). - Include patch to factor out utility routines in kselftests written in assembler. - Specify -ffreestanding when building TPIDR2 test. v3: - Skip FFR rather than predicate registers in sve_flush_live(). - Don't assume a bool is all zeros in sve_flush_live() as per AAPCS. - Don't redundantly specify a zero index when clearing FFR. v2: - Fix several issues with !SME and !SVE configurations. - Preserve TPIDR2 when creating a new thread/process unless CLONE_SETTLS is set. - Report traps due to using features in an invalid mode as SIGILL. - Spell out streaming mode behaviour in SVE ABI documentation more directly. - Document TPIDR2 in the ABI document. - Use SMSTART and SMSTOP rather than read/modify/write sequences. - Rework logic for exiting streaming mode on syscall. - Don't needlessly initialise SVCR on access trap. - Always restore SME VL for userspace if SME traps are disabled. - Only yield to encourage preemption every 128 iterations in za-test, otherwise do a getpid(), and validate SVCR after syscall. - Leave streaming mode disabled except when reading the vector length in za-test, and disable ZA after detecting a mismatch. - Add SME support to vlset. - Clarifications and typo fixes in comments. - Move sme_alloc() forward declaration back a patch.

[PATCH] kselftest: alsa: Add test case for writing invalid values

by Mark Brown

Attempt to write various invalid values for control types we know about and check that something sensible happens. The ABI isn't quite as clearly defined as one might like, rather than generating an error when an invalid value is written many devices will silently rewrite the value into one that is valid for the control. The exact value chosen is not predictable so in the case the write succeeds we just check that the value we read back is one that is valid for the control.

[PATCH v5 00/20] tcp: Initial support for RFC5925 auth option

by Leonard Crestez

This is similar to TCP-MD5 in functionality but it's sufficiently different that packet formats and interfaces are incompatible. Compared to TCP-MD5 more algorithms are supported and multiple keys can be used on the same connection but there is still no negotiation mechanism. Expected use-case is protecting long-duration BGP/LDP connections between routers using pre-shared keys. The goal of this series is to allow routers using the Linux TCP stack to interoperate with vendors such as Cisco and Juniper. Both algorithms described in RFC5926 are implemented but the code is not very easily extensible beyond that. In particular there are several code paths making stack allocations based on RFC5926 maximum, those would have to be increased. Support for arbitrary algorithms was requested in reply to previous posts but I believe there is no real use case for that. The current implementation is somewhat loose regarding configuration: * Overlaping MKTs can be configured despite what RFC5925 says * Current key can be deleted. RFC says this shouldn't be allowed but enforcing this belongs at an admin shell rather than in the kernel. * If multiple keys are valid for a destination the kernel picks one in an unpredictable manner (this can be overridden). These conditions could be tightened but it is not clear the kernel should spend effort to prevent misconfiguration from userspace. The current code is largely feature complete and well-tested but I am somewhat stuck on next steps for getting this into upstream. Any suggestions would be very welcome Here are some known flaws and limitations: * Unsigned packets are sent if AO is active but no keys are found. * Crypto API is used with buffers on the stack and inside struct sock, this might not work on all arches. I'm currently only testing x64 VMs * Interaction with TCP-MD5 not tested in all corners. * Interaction with FASTOPEN not tested and unlikely to work because sequence number assumptions for syn/ack. * No way to limit keys on a per-port basis (used to be implicit with per-socket keys). * Not clear if crypto_ahash_setkey might sleep. If some implementation do that then maybe they could be excluded through alloc flags. * Traffic key is not cached (reducing performance) * No caching or hashing for key lookups so this will scale poorly with many keys There is relatively little code sharing with the TCP_MD5SIG feature and earlier versions shared even less. Unlike MD5 the AO feature is kept separate from the rest of the TCP code and reusing code would require many unrelated cleanup changes. I'm not convinced that "authopt" is particularly good naming convention, this name is a personal invention that does not appear anywhere else. The RFC calls this "tcp-ao". Perhaps TCP_AOSIG would be a better name and it would also make the close connection to TCP_MD5SIG more visible? Some testing support is included in nettest and fcnal-test.sh, similar to the current level of tcp-md5 testing. A more elaborate test suite using pytest and scapy is available out of tree: https://github.com/cdleonard/tcp-authopt-test That test suite is much larger that the kernel code and did not receive many comments in previous ports so I will attempt to push it separately (if at all). Changes for frr (old): https://github.com/FRRouting/frr/pull/9442 That PR was made early for ABI feedback, it has many issues. Changes for yabgp (old): https://github.com/cdleonard/yabgp/commits/tcp_authopt This can be used for easy interoperability testing with cisco/juniper/etc. Would need updates for global keys to avoid leaks Changes since PATCH v4: * Move the traffic_key context_bytes header to stack. If it's a constant string then ahash can fail unexpectedly. * Fix allowing unsigned traffic if all keys are marked norecv. * Fix crashing in __tcp_authopt_alg_init on failure. * Try to respect the rnextkeyid from SYN on SYNACK (new patch) * Fix incorrect check for TCP_AUTHOPT_KEY_DEL in __tcp_authopt_select_key * Improve docs on __tcp_authopt_select_key * Fix build with CONFIG_PROC_FS=n (kernel build robot) * Fix build with CONFIG_IPV6=n (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1640273966.git.cdleonard@gmail.com/ Changes since PATCH v3: * Made keys global (per-netns rather than per-sock). * Add /proc/net/tcp_authopt with a table of keys (not sockets). * Fix part of the shash/ahash conversion having slipped from patch 3 to patch 5 * Fix tcp_parse_sig_options assigning NULL incorrectly when both MD5 and AO are disabled (kernel build robot) * Fix sparse endianness warnings in prefix match (kernel build robot) * Fix several incorrect RCU annotations reported by sparse (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1638962992.git.cdleonard@gmail.com/ Changes since PATCH v2: * Protect tcp_authopt_alg_get/put_tfm with local_bh_disable instead of preempt_disable. This caused signature corruption when send path executing with BH enabled was interrupted by recv. * Fix accepted keyids not configured locally as "unexpected". If any key is configured that matches the peer then traffic MUST be signed. * Fix issues related to sne rollover during handshake itself. (Francesco) * Implement and test prefixlen (David) * Replace shash with ahash and reuse some of the MD5 code (Dmitry) * Parse md5+ao options only once in the same function (Dmitry) * Pass tcp_authopt_info into inbound check path, this avoids second rcu dereference for same packet. * Pass tcp_request_socket into inbound check path instead of just listen socket. This is required for SNE rollover during handshake and clearifies ISN handling. * Do not allow disabling via sysctl after enabling once, this is difficult to support well (David) * Verbose check for sysctl_tcp_authopt (Dmitry) * Use netif_index_is_l3_master (David) * Cleanup ipvx_addr_match (David) * Add a #define tcp_authopt_needed to wrap static key usage because it looks nicer. * Replace rcu_read_lock with rcu_dereference_protected in SNE updates (Eric) * Remove test suite Link: https://lore.kernel.org/netdev/cover.1635784253.git.cdleonard@gmail.com/ Changes since PATCH v1: * Implement Sequence Number Extension * Implement l3index for vrf: TCP_AUTHOPT_KEY_IFINDEX as equivalent of TCP_MD5SIG_FLAG_IFINDEX * Expand TCP-AO tests in fcnal-test.sh to near-parity with md5. * Show addr/port on failure similar to md5 * Remove tox dependency from test suite (create venv directly) * Switch default pytest output format to TAP (kselftest standard) * Fix _copy_from_sockptr_tolerant stack corruption on short sockopts. This was covered in test but error was invisible without STACKPROTECTOR=y * Fix sysctl_tcp_authopt check in tcp_get_authopt_val before memset. This was harmless because error code is checked in getsockopt anyway. * Fix dropping md5 packets on all sockets with AO enabled * Fix checking (key->recv_id & TCP_AUTHOPT_KEY_ADDR_BIND) instead of key->flags in tcp_authopt_key_match_exact * Fix PATCH 1/19 not compiling due to missing "int err" declaration * Add ratelimited message for AO and MD5 both present * Export all symbols required by CONFIG_IPV6=m (again) * Fix compilation with CONFIG_TCP_AUTHOPT=y CONFIG_TCP_MD5SIG=n * Fix checkpatch issues * Pass -rrequirements.txt to tox to avoid dependency variation. Link: https://lore.kernel.org/netdev/cover.1632240523.git.cdleonard@gmail.com/ Changes since RFCv3: * Implement TCP_AUTHOPT handling for timewait and reset replies. Write tests to execute these paths by injecting packets with scapy * Handle combining md5 and authopt: if both are configured use authopt. * Fix locking issues around send_key, introduced in on of the later patches. * Handle IPv4-mapped-IPv6 addresses: it used to be that an ipv4 SYN sent to an ipv6 socket with TCP-AO triggered WARN * Implement un-namespaced sysctl disabled this feature by default * Allocate new key before removing any old one in setsockopt (Dmitry) * Remove tcp_authopt_key_info.local_id because it's no longer used (Dmitry) * Propagate errors from TCP_AUTHOPT getsockopt (Dmitry) * Fix no-longer-correct TCP_AUTHOPT_KEY_DEL docs (Dmitry) * Simplify crypto allocation (Eric) * Use kzmalloc instead of __GFP_ZERO (Eric) * Add static_key_false tcp_authopt_needed (Eric) * Clear authopt_info copied from oldsk in __tcp_authopt_openreq (Eric) * Replace memcmp in ipv4 and ipv6 addr comparisons (Eric) * Export symbols for CONFIG_IPV6=m (kernel test robot) * Mark more functions static (kernel test robot) * Fix build with CONFIG_PROVE_RCU_LIST=y (kernel test robot) Link: https://lore.kernel.org/netdev/cover.1629840814.git.cdleonard@gmail.com/ Changes since RFCv2: * Removed local_id from ABI and match on send_id/recv_id/addr * Add all relevant out-of-tree tests to tools/testing/selftests * Return an error instead of ignoring unknown flags, hopefully this makes it easier to extend. * Check sk_family before __tcp_authopt_info_get_or_create in tcp_set_authopt_key * Use sock_owned_by_me instead of WARN_ON(!lockdep_sock_is_held(sk)) * Fix some intermediate build failures reported by kbuild robot * Improve documentation Link: https://lore.kernel.org/netdev/cover.1628544649.git.cdleonard@gmail.com/ Changes since RFC: * Split into per-topic commits for ease of review. The intermediate commits compile with a few "unused function" warnings and don't do anything useful by themselves. * Add ABI documention including kernel-doc on uapi * Fix lockdep warnings from crypto by creating pools with one shash for each cpu * Accept short options to setsockopt by padding with zeros; this approach allows increasing the size of the structs in the future. * Support for aes-128-cmac-96 * Support for binding addresses to keys in a way similar to old tcp_md5 * Add support for retrieving received keyid/rnextkeyid and controling the keyid/rnextkeyid being sent.

[PATCH v2 0/5] selftests/resctrl: Add resctrl_tests into kselftest set

by Shaopeng Tan

Hello, The aim of this series is to make resctrl_tests run by using kselftest framework. - I modify Makefile of resctrl_test and Makefile of selftest, to build/run resctrl_tests by using kselftest framework. - I set the limited time for resctrl_tests to 120 seconds, to ensure the resctrl_tests finish in limited time. - When resctrl file system is not supported or resctrl_tests is not run as root, return skip code of kselftest. - If it is not finish in limited time, terminate resctrl_tests same as executing ctrl+c. Difference from v1: - I change the order of patches according to Reinette's review. - "LDLIBS + = -lnuma" has no dependencies on this patch series, delete it from [PATCH v2 2/5]. - I separate the license info of Makefile into a new patch [PATCH v2 3/5]. - I separate "limited time" into a new patch [PATCH v2 4/5]. (There is no change in [PATCH v2 1/5] and [PATCH v2 5/5]) In addition, I think 120s is not a problem since some tests have longer timeout (e.g. net test is 300s), please let me know if this is wrong Thanks, Shaopeng Tan (5): selftests/resctrl: Kill the child process created by fork() when the SIGTERM signal comes selftests/resctrl: Make resctrl_tests run using kselftest framework selftests/resctrl: Add license to resctrl_test Makefile selftests/resctrl: Change default limited time to 120 seconds for resctrl_tests selftests/resctrl: Return KSFT_SKIP(4) if resctrlfile system is not supported or resctrl is not run as root tools/testing/selftests/Makefile | 1 + tools/testing/selftests/resctrl/Makefile | 20 +++++++------------ .../testing/selftests/resctrl/resctrl_tests.c | 4 ++-- tools/testing/selftests/resctrl/resctrl_val.c | 1 + tools/testing/selftests/resctrl/settings | 1 + 5 files changed, 12 insertions(+), 15 deletions(-) create mode 100644 tools/testing/selftests/resctrl/settings -- 2.27.0

[PATCH v3 0/6] kunit: refactor assertions to use less stack

by Daniel Latypov

*** BLURB HERE *** Every KUNIT_ASSERT/EXPECT() invocation puts a `kunit_assert` object onto the stack. The most common one is `kunit_binary_assert` which is 88 bytes on UML. So in the cases where the compiler doesn't optimize this away, we can very quickly blow up the stack size. This series implements Linus' suggestion in [1]. Namely, we split out the file, line number, and assert_type (EXPECT/ASSERT) out of kunit_assert. We can also drop the entirely unused `struct kunit *test` field, saving a bit more space as well. All together, sizeof(struct kunit_assert) went from 48 to 24 on UML. Note: the other assert types are bigger, see [2]. This series also adds in an example test that uses all the base KUNIT_EXPECT macros to both advertise their existence to new users and serve as a smoketest for all these changes here. [1] https://groups.google.com/g/kunit-dev/c/i3fZXgvBrfA/m/VULQg1z6BAAJ [2] e.g. consider the most commonly used assert (also the biggest) struct kunit_binary_assert { struct kunit_assert assert; const char *operation; const char *left_text; long long left_value; const char *right_text; long long right_value; }; So sizeof(struct kunit_binary_assert) = went from 88 to 64. I.e. only a 27% reduction instead of 50% in the most common case. All 3 of the `const char*` could be split out into a `static` var as well, but that's a bit trickier to do with how all the macros are written. === Changelog === v1 -> v2: * made the new example test more focused on documenting the macros rather than using them all as a smoketest * s/kunit_failed_assertion()/kunit_do_failed_assertion() * added `unlikely()` to `if(!(pass))` check in KUNIT_ASSERTION() v2 -> v3: * elaborate on intermediate TODO in patch 5 (deleted in patch 6) * update with more Reviewed-by's Daniel Latypov (6): kunit: add example test case showing off all the expect macros kunit: move check if assertion passed into the macros kunit: drop unused kunit* field in kunit_assert kunit: factor out kunit_base_assert_format() call into kunit_fail() kunit: split out part of kunit_assert into a static const kunit: drop unused assert_type from kunit_assert and clean up macros include/kunit/assert.h | 88 +++++++++++----------------------- include/kunit/test.h | 53 ++++++++++---------- lib/kunit/assert.c | 15 ++---- lib/kunit/kunit-example-test.c | 42 ++++++++++++++++ lib/kunit/test.c | 27 +++++------ 5 files changed, 117 insertions(+), 108 deletions(-) base-commit: ad659ccb5412874c6a89d3588cb18857c00e9d0f -- 2.34.1.703.g22d0c6ccf7-goog

[PATCH 0/5] kunit: decrease layers of assertion macros

by Daniel Latypov

Note: this series applies on top of the series reducing stack usage, https://lore.kernel.org/linux-kselftest/20220113165931.451305-1-dlatypov@go… There's no real smenatic dependency between these, just potential for merge conflicts. The current layout of the assertion macros is confusing. Here's the call chain for KUNIT_EXPECT_EQ() and KUNIT_EXPECT_EQ_MSG() KUNIT_EXPECT_EQ => KUNIT_BINARY_EQ_ASSERTION => # note: not shared with the _MSG variant KUNIT_BINARY_EQ_MSG_ASSERTION => KUNIT_BASE_EQ_MSG_ASSERTION => KUNIT_BASE_BINARY_ASSERTION KUNIT_EXPECT_EQ_MSG => KUNIT_BINARY_EQ_MSG_ASSERTION => KUNIT_BASE_EQ_MSG_ASSERTION => KUNIT_BASE_BINARY_ASSERTION After this series KUNIT_EXPECT_EQ => KUNIT_EXPECT_EQ_MSG => KUNIT_BINARY_INT_ASSERTION => KUNIT_BASE_BINARY_ASSERTION The current macro layout tries hard to reduce duplication, but comes at the cost of a lot of intermediates that can simply vanish. The same call-chain again, but annotated with the info we add: KUNIT_EXPECT_EQ => specify we're an EXPECT, not an ASSERT KUNIT_BINARY_EQ_ASSERTION => specify we have a NULL msg KUNIT_BINARY_EQ_MSG_ASSERTION => specify we work with ints, not ptrs KUNIT_BASE_EQ_MSG_ASSERTION => specify that the op is '==' KUNIT_BASE_BINARY_ASSERTION We can see that each level of the chain only specifes one parameter at a time. We've taken the concept of DRY too far. The following is a full snippet of all the macros needed for KUNIT_EXPECT_EQ, showing that a bit of repetition is just fine: #define KUNIT_BINARY_INT_ASSERTION(test, \ assert_type, \ left, \ op, \ right, \ fmt, \ ...) \ KUNIT_BASE_BINARY_ASSERTION(test, \ kunit_binary_assert, \ KUNIT_INIT_BINARY_ASSERT_STRUCT, \ assert_type, \ left, op, right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_EXPECT_EQ(test, left, right) \ KUNIT_EXPECT_EQ_MSG(test, left, right, NULL) #define KUNIT_EXPECT_EQ_MSG(test, left, right, fmt, ...) \ KUNIT_BINARY_INT_ASSERTION(test, \ KUNIT_EXPECTATION, \ left, ==, right, \ fmt, \ ##__VA_ARGS__) as opposed to our current DRYer version #define KUNIT_BASE_EQ_MSG_ASSERTION(test, \ assert_class, \ ASSERT_CLASS_INIT, \ assert_type, \ left, \ right, \ fmt, \ ...) \ KUNIT_BASE_BINARY_ASSERTION(test, \ assert_class, \ ASSERT_CLASS_INIT, \ assert_type, \ left, ==, right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_BINARY_EQ_MSG_ASSERTION(test, assert_type, left, right, fmt, ...)\ KUNIT_BASE_EQ_MSG_ASSERTION(test, \ kunit_binary_assert, \ KUNIT_INIT_BINARY_ASSERT_STRUCT, \ assert_type, \ left, \ right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_BINARY_EQ_ASSERTION(test, assert_type, left, right) \ KUNIT_BINARY_EQ_MSG_ASSERTION(test, \ assert_type, \ left, \ right, \ NULL) #define KUNIT_EXPECT_EQ(test, left, right) \ KUNIT_BINARY_EQ_ASSERTION(test, KUNIT_EXPECTATION, left, right) #define KUNIT_EXPECT_EQ_MSG(test, left, right, fmt, ...) \ KUNIT_BINARY_EQ_MSG_ASSERTION(test, \ KUNIT_EXPECTATION, \ left, \ right, \ fmt, \ ##__VA_ARGS__) Daniel Latypov (5): kunit: make KUNIT_EXPECT_EQ() use KUNIT_EXPECT_EQ_MSG(), etc. kunit: drop unused intermediate macros for ptr inequality checks kunit: reduce layering in string assertion macros kunit: decrease macro layering for integer asserts kunit: decrease macro layering for EQ/NE asserts include/kunit/test.h | 660 ++++++++++--------------------------------- 1 file changed, 142 insertions(+), 518 deletions(-) -- 2.34.1.703.g22d0c6ccf7-goog

[RFC 00/10] drm: selftests: Convert to KUnit

by Michał Winiarski

KUnit unifies the test structure and provides helper tools that simplify the development. Basic use case allows running tests as regular processes, leveraging User Mode Linux. For example, to execute all DRM unit tests: ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm (the tool also allows using QEMU instead of UML by adding e.g. --arch=x86_64) For developers - it means that it's easier to run unit tests on the development machine, tightening the feedback loop. When using UML, it also simplifies using gdb for debug (since the kernel is just a regular process). For CI systems - DRM tests can be moved from being executed on device under test (that's also running IGTs and so on) to being executed on buildsystem during build (just like checkpatch.pl). All tests were renamed - IGT prefix is no longer used. Compared to selftests executed by CI using IGT, there's one functional regression - KUnit test runner is not catching WARNs. To solve this, we could either go in the similar direction that UBSAN went in: 1195505 ("kunit: ubsan integration") Or we could expand the test runner to catch WARN signature in dmesg.

[PATCH V2 00/10] selftests: Fix separate output directory builds

by Muhammad Usama Anjum

[PATCH v5 net-next 0/4] Add ethtool interface for RClocks

by Maciej Machnikowski

Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements. Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to synchronize to reference frequency sources. This patch series is a prerequisite for EEC object and adds ability to enable recovered clocks in the physical layer of the netdev object. Recovered clocks can be used as one of the reference signal by the EEC. Further work is required to add the DPLL subsystem, link it to the netdev object and create API to read the EEC DPLL state. v5: - rewritten the documentation - fixed doxygen headers v4: - Dropped EEC_STATE reporting (TBD: DPLL subsystem) - moved recovered clock configuration to ethtool netlink v3: - remove RTM_GETRCLKRANGE - return state of all possible pins in the RTM_GETRCLKSTATE - clarify documentation v2: - improved documentation - fixed kdoc warning RFC history: v2: - removed whitespace changes - fix issues reported by test robot v3: - Changed naming from SyncE to EEC - Clarify cover letter and commit message for patch 1 v4: - Removed sync_source and pin_idx info - Changed one structure to attributes - Added EEC_SRC_PORT flag to indicate that the EEC is synchronized to the recovered clock of a port that returns the state v5: - add EEC source as an optiona attribute - implement support for recovered clocks - align states returned by EEC to ITU-T G.781 v6: - fix EEC clock state reporting - add documentation - fix descriptions in code comments Maciej Machnikowski (4): ice: add support detecting features based on netlist ethtool: Add ability to configure recovered clock for SyncE feature ice: add support for monitoring SyncE DPLL state ice: add support for recovered clocks Documentation/networking/ethtool-netlink.rst | 62 ++++ drivers/net/ethernet/intel/ice/ice.h | 7 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 70 ++++- drivers/net/ethernet/intel/ice/ice_common.c | 224 +++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 20 +- drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_ethtool.c | 96 +++++++ drivers/net/ethernet/intel/ice/ice_lib.c | 6 +- drivers/net/ethernet/intel/ice/ice_ptp.c | 35 +++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 49 ++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 36 +++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + include/linux/ethtool.h | 9 + include/uapi/linux/ethtool_netlink.h | 21 ++ net/ethtool/Makefile | 3 +- net/ethtool/netlink.c | 20 ++ net/ethtool/netlink.h | 4 + net/ethtool/synce.c | 267 ++++++++++++++++++ 18 files changed, 929 insertions(+), 4 deletions(-) create mode 100644 net/ethtool/synce.c -- 2.26.3

[PATCH AUTOSEL 5.10 058/116] selftests/ftrace: make kprobe profile testcase description unique

by Sasha Levin

From: Heiko Carstens <hca(a)linux.ibm.com> [ Upstream commit e5992f373c6eed6d09e5858e9623df1259b3ce30 ] Commit 32f6e5da83c7 ("selftests/ftrace: Add kprobe profile testcase") added a new kprobes testcase, but has a description which does not describe what the test case is doing and is duplicating the description of another test case. Therefore change the test case description, so it is unique and then allows easily to tell which test case actually passed or failed.

[PATCH AUTOSEL 5.16 117/217] selftests/ftrace: make kprobe profile testcase description unique

by Sasha Levin

From: Heiko Carstens <hca(a)linux.ibm.com> [ Upstream commit e5992f373c6eed6d09e5858e9623df1259b3ce30 ] Commit 32f6e5da83c7 ("selftests/ftrace: Add kprobe profile testcase") added a new kprobes testcase, but has a description which does not describe what the test case is doing and is duplicating the description of another test case. Therefore change the test case description, so it is unique and then allows easily to tell which test case actually passed or failed.
