[PATCH net 0/2] selftests/bpf: fix ima_setup.sh missing issue

by Hangbin Liu

The ima_setup.sh is needed by test_progs test_ima. But the file is missed if we build test_progs separately or installed bpf test to another folder. This patch set fixed the issue in 2 different scenarios.

[PATCH bpf v4 0/3] Fix kprobe_multi interface issues for 5.18

by Eugene Syromiatnikov

Hello. While [1] seems to require additional work[2] due to changes in the interface (and it has already been re-targeted for bpf-next), I would like to ask to consider the following three patches, that fix possible out-of-bounds write, properly disable the interface for 32-bit compat user space, and prepare the libbpf interface change, for the 5.18 release. Thank you.

[PATCH] kunit: tool: refactor internal kconfig handling, allow overriding

by Daniel Latypov

Currently, you cannot ovewrwrite what's in your kunitconfig via --kconfig_add. Nor can you override something in a qemu_config via either means. This patch makes it so we have this level of priority * --kconfig_add * kunitconfig file (the default or the one from --kunitconfig) * qemu_config The rationale for this order is that the more "dynamic" sources of kconfig options should take priority. --kconfig_add is obviously the most dynamic. And for kunitconfig, users probably tweak the file manually or specify --kunitconfig more often than they delve into qemu_config python files. And internally, we convert the kconfigs from a python list into a set or dict fairly often. We should just use a dict internally. We exposed the set transform in the past since we didn't define __eq__, so also take the chance to shore up the kunit_kconfig.Kconfig interface. Example ======= Let's consider the unrealistic example where someone would want to disable CONFIG_KUNIT. I.e. they run $ ./tools/testing/kunit/kunit.py config --kconfig_add=CONFIG_KUNIT=n Before ------ We'd write the following > # CONFIG_KUNIT is not set > CONFIG_KUNIT_ALL_TESTS=y > CONFIG_KUNIT_TEST=y > CONFIG_KUNIT=y > CONFIG_KUNIT_EXAMPLE_TEST=y And we'd error out with > ERROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config. > This is probably due to unsatisfied dependencies. > Missing: # CONFIG_KUNIT is not set After ----- We'd write the following > # CONFIG_KUNIT is not set > CONFIG_KUNIT_TEST=y > CONFIG_KUNIT_ALL_TESTS=y > CONFIG_KUNIT_EXAMPLE_TEST=y And we'd error out with > ERROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config. > This is probably due to unsatisfied dependencies. > Missing: CONFIG_KUNIT_EXAMPLE_TEST=y, CONFIG_KUNIT_TEST=y, CONFIG_KUNIT_ALL_TESTS=y Signed-off-by: Daniel Latypov <dlatypov(a)google.com> --- tools/testing/kunit/kunit_config.py | 49 +++++++++++++++----------- tools/testing/kunit/kunit_kernel.py | 21 ++++++----- tools/testing/kunit/kunit_tool_test.py | 45 ++++++++++------------- 3 files changed, 59 insertions(+), 56 deletions(-) diff --git a/tools/testing/kunit/kunit_config.py b/tools/testing/kunit/kunit_config.py index 75a8dc1683d4..89443400b17e 100644 --- a/tools/testing/kunit/kunit_config.py +++ b/tools/testing/kunit/kunit_config.py @@ -8,7 +8,7 @@ from dataclasses import dataclass import re -from typing import List, Set +from typing import Dict, Iterable, Set CONFIG_IS_NOT_SET_PATTERN = r'^# CONFIG_(\w+) is not set$' CONFIG_PATTERN = r'^CONFIG_(\w+)=(\S+|".*")$' @@ -32,35 +32,46 @@ class Kconfig: """Represents defconfig or .config specified using the Kconfig language.""" def __init__(self) -> None: -

[PATCH v2 0/6] userfaultfd: add /dev/userfaultfd for fine grained access control

by Axel Rasmussen

This series is based on torvalds/master, but additionally the run_vmtests.sh changes assume my refactor [1] has been applied first. The series is split up like so: - Patch 1 is a simple fixup which we should take in any case (even by itself). - Patches 2-4 add the feature, basic support for it to the selftest, and docs. - Patches 5-6 make the selftest configurable, so you can test one or the other instead of always both. If we decide this is overcomplicated, we could just drop these two patches and take the rest of the series. [1]: https://patchwork.kernel.org/project/linux-mm/patch/20220421224928.1848230-… Changelog: v1->v2: - Add documentation update. - Test *both* userfaultfd(2) and /dev/userfaultfd via the selftest.

[PATCH bpf-next v9 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. v9 changes: Fixed selftests for no_alu32.

[PATCH net 0/2] selftests: net: add missing tests to Makefile

by Hangbin Liu

When generating the selftests to another folder, the fixed tests are missing as they are not in Makefile. The missing tests are generated by command: $ for f in $(ls *.sh); do grep -q $f Makefile || echo $f; done I think there need a way to notify the developer when they created a new file in selftests folder. Maybe a bot like bluez.test.bot or kernel test robot could help do that?
