[PATCH v2 0/2] begin KTAP spec v2 process

by frowand.list＠gmail.com

From: Frank Rowand <frank.rowand(a)sony.com> The process to create version 2 of the KTAP Specification is documented in email discussions. I am attempting to capture this information at https://elinux.org/Test_Results_Format_Notes#KTAP_version_2 I am already not following the suggested process, which says: "...please try to follow this principal of one major topic per email thread." I think that is ok in this case because the two patches are related and (hopefully) not controversial. Changes since patch version 1: - drop patch 1/2. Jonathan Corbet has already applied this patch into version 1 of the Specification - rename patch 2/2 to patch 1/2, with updated patch comment - add new patch 2/2 Frank Rowand (2): ktap_v2: change version to 2-rc in KTAP specification ktap_v2: change "version 1" to "version 2" in examples Documentation/dev-tools/ktap.rst | 25 +++++++++++++------------ 1 file changed, 13 insertions(+), 12 deletions(-) -- Frank Rowand <frank.rowand(a)sony.com>

[RFC PATCH 0/2] kunit: Support redirecting function calls

by David Gow

When writing tests, it'd often be very useful to be able to intercept calls to a function in the code being tested and replace it with a test-specific stub. This has always been an obviously missing piece of KUnit, and the solutions always involve some tradeoffs with cleanliness, performance, or impact on non-test code. See the folowing document for some of the challenges: https://kunit.dev/mocking.html This series consists of two prototype patches which add support for this sort of redirection to KUnit tests: 1: static_stub: Any function which might want to be intercepted adds a call to a macro which checks if a test has redirected calls to it, and calls the corresponding replacement. 2: ftrace_stub: Functions are intercepted using ftrace and livepatch. This doesn't require adding a new prologue to each function being replaced, but does have more dependencies (which restricts it to a small number of architectures, not including UML), and doesn't work well with inline functions. The API for both implementations is very similar, so it should be easy to migrate from one to the other if necessary. Both of these implementations restrict the redirection to the test context: it is automatically undone after the KUnit test completes, and does not affect calls in other threads. If CONFIG_KUNIT is not enabled, there should be no overhead in either implementation. Does either (or both) of these features sound useful, and is this sort-of API the right model? (Personally, I think there's a reasonable scope for both.) Is anything obviously missing or wrong? Do the names, descriptions etc. make any sense? Note that these patches are definitely still at the "prototype" level, and things like error-handling, documentation, and testing are still pretty sparse. There is also quite a bit of room for optimisation. These'll all be improved for v1 if the concept seems good.

[PATCH] kselftest/arm64: Fix ABI header directory location

by Mark Brown

Currently the arm64 kselftests attempt to locate the ABI headers using custom logic which doesn't work correctly in the case of out of tree builds if KBUILD_OUTPUT is not specified. Since lib.mk defines KHDR_INCLUDES with the appropriate flags we can simply remove the custom logic and use that instead. Signed-off-by: Mark Brown <broonie(a)kernel.org> --- This fix is required to get us able to run the arm64 kselftests in KernelCI, it does out of tree kselftest builds triggering the issue especially in conjunction with the addition of the new definitions for SME. tools/testing/selftests/arm64/Makefile | 11 +---------- 1 file changed, 1 insertion(+), 10 deletions(-) diff --git a/tools/testing/selftests/arm64/Makefile b/tools/testing/selftests/arm64/Makefile index 1e8d9a8f59df..9460cbe81bcc 100644 --- a/tools/testing/selftests/arm64/Makefile +++ b/tools/testing/selftests/arm64/Makefile @@ -17,16 +17,7 @@ top_srcdir = $(realpath ../../../../) # Additional include paths needed by kselftest.h and local headers CFLAGS += -I$(top_srcdir)/tools/testing/selftests/ -# Guessing where the Kernel headers could have been installed -# depending on ENV config -ifeq ($(KBUILD_OUTPUT),) -khdr_dir = $(top_srcdir)/usr/include -else -# the KSFT preferred location when KBUILD_OUTPUT is set -khdr_dir = $(KBUILD_OUTPUT)/kselftest/usr/include -endif - -CFLAGS += -I$(khdr_dir) +CFLAGS += $(KHDR_INCLUDES) export CFLAGS export top_srcdir -- 2.30.2

[PATCH v10 0/8] cgroup/cpuset: Major cpu partition code restructuring

by Waiman Long

v10: - Relax constraints for changes made to "cpuset.cpus" and "cpuset.cpus.partition" as suggested. Now almost all changes are allowed. v9: - Add a new patch 1 to remove the child cpuset restriction on parent's "cpuset.cpus". - Relax initial root partition entry limitation to allow cpuset.cpus to overlap that of parent's. - An "isolated invalid" displayed type is added to cpuset.cpus.partition. - Resetting partition root to "member" will leave child partition root as invalid. - Update documentation and test accordingly. v8: - Reorganize the patch series and rationalize the features and constraints of a partition. - Update patch descriptions and documentation accordingly. This patchset include the following enhancements to the cpuset v2 partition code. 1) Allow partitions that have no task to have empty effective cpus. 2) Relax the constraints on what changes are allowed in cpuset.cpus and cpuset.cpus.partition. However, the partition remain invalid until the constraints of a valid partition root is satisfied. 3) Add a new "isolated" partition type for partitions with no load balancing which is available in v1 but not yet in v2. 4) Allow the reading of cpuset.cpus.partition to include a reason string as to why the partition remain invalid. In addition, the cgroup-v2.rst documentation file is updated and a self test is added to verify the correctness the partition code.

[PATCH v5 0/4] memcg: introduce per-memcg proactive reclaim

by Yosry Ahmed

This patch series adds a memory.reclaim proactive reclaim interface. The rationale behind the interface and how it works are in the first patch. --- Changes in V5: - Fixed comment formating and added Co-developed-by in patch 1. - Modified selftest to work if swap is enabled or not, and retry multiple times to wait for background allocation before failing with a clear message. Changes in V4: mm/memcontrol.c: - Return -EINTR on signal_pending(). - On the final retry, drain percpu lru caches hoping that it might introduce some evictable pages for reclaim. - Simplified the retry loop as suggested by Dan Schatzberg. selftests: - Always return -errno on failure from cg_write() (whether open() or write() fail), also update cg_read() and read_text() to return -errno as well for consistency. Also make sure to correctly check that the whole buffer was written in cg_write(). - Added a maximum number of retries for the reclaim selftest. Changes in V3: - Fix cg_write() (in patch 2) to properly return -1 if open() fails and not fail if len == errno. - Remove debug printf() in patch 3. Changes in V2: - Add the interface to root as well. - Added a selftest. - Documented the interface as a nested-keyed interface, which makes adding optional arguments in the future easier (see doc updates in the first patch). - Modified the commit message to reflect changes and added a timeout argument as a suggested possible extension - Return -EAGAIN if the kernel fails to reclaim the full requested amount. --- Shakeel Butt (1): memcg: introduce per-memcg reclaim interface Yosry Ahmed (3): selftests: cgroup: return -errno from cg_read()/cg_write() on failure selftests: cgroup: fix alloc_anon_noexit() instantly freeing memory selftests: cgroup: add a selftest for memory.reclaim Documentation/admin-guide/cgroup-v2.rst | 21 ++++ mm/memcontrol.c | 45 +++++++ tools/testing/selftests/cgroup/cgroup_util.c | 44 +++---- .../selftests/cgroup/test_memcontrol.c | 114 +++++++++++++++++- 4 files changed, 197 insertions(+), 27 deletions(-) -- 2.36.0.rc2.479.g8af0fa9b8e-goog

[PATCH bpf-next v8 0/5] New BPF helpers to accelerate synproxy

by Maxim Mikityanskiy

The first patch of this series is a documentation fix. The second patch allows BPF helpers to accept memory regions of fixed size without doing runtime size checks. The two next patches add new functionality that allows XDP to accelerate iptables synproxy. v1 of this series [1] used to include a patch that exposed conntrack lookup to BPF using stable helpers. It was superseded by series [2] by Kumar Kartikeya Dwivedi, which implements this functionality using unstable helpers. The third patch adds new helpers to issue and check SYN cookies without binding to a socket, which is useful in the synproxy scenario. The fourth patch adds a selftest, which includes an XDP program and a userspace control application. The XDP program uses socketless SYN cookie helpers and queries conntrack status instead of socket status. The userspace control application allows to tune parameters of the XDP program. This program also serves as a minimal example of usage of the new functionality. The last patch exposes the new helpers to TC BPF. The draft of the new functionality was presented on Netdev 0x15 [3]. v2 changes: Split into two series, submitted bugfixes to bpf, dropped the conntrack patches, implemented the timestamp cookie in BPF using bpf_loop, dropped the timestamp cookie patch. v3 changes: Moved some patches from bpf to bpf-next, dropped the patch that changed error codes, split the new helpers into IPv4/IPv6, added verifier functionality to accept memory regions of fixed size. v4 changes: Converted the selftest to the test_progs runner. Replaced some deprecated functions in xdp_synproxy userspace helper. v5 changes: Fixed a bug in the selftest. Added questionable functionality to support new helpers in TC BPF, added selftests for it. v6 changes: Wrap the new helpers themselves into #ifdef CONFIG_SYN_COOKIES, replaced fclose with pclose and fixed the MSS for IPv6 in the selftest. v7 changes: Fixed the off-by-one error in indices, changed the section name to "xdp", added missing kernel config options to vmtest in CI. v8 changes: Properly rebased, dropped the first patch (the same change was applied by someone else), updated the cover letter.
