[PATCH v3 55/56] selftests: kselftest_harness.h: partially fix kernel-doc markups

by Mauro Carvalho Chehab

The kernel-doc markups on this file are weird: they don't follow what's specified at: Documentation/doc-guide/kernel-doc.rst In particular, markups should use this format: identifier - description and not this: identifier(args) The way the definitions are inside this file cause the parser to completely miss the identifier name of each function. This prevents improving the script to do some needed validation tests. Address this part. Yet, furter changes are needed in order for it to fully follow the specs.

[PATCH] selftests/powerpc/eeh: disable kselftest timeout setting for eeh-basic

by Po-Hsu Lin

The eeh-basic test got its own 60 seconds timeout (defined in commit 414f50434aa2 "selftests/eeh: Bump EEH wait time to 60s") per breakable device. And we have discovered that the number of breakable devices varies on different hardware. The device recovery time ranges from 0 to 35 seconds. In our test pool it will take about 30 seconds to run on a Power8 system that with 5 breakable devices, 60 seconds to run on a Power9 system that with 4 breakable devices. Thus it's better to disable the default 45 seconds timeout setting in the kselftest framework to give it a chance to finish. And let the test to take care of the timeout control.

[PATCH v3] fat: Add KUnit tests for checksums and timestamps

by David Gow

Add some basic sanity-check tests for the fat_checksum() function and the fat_time_unix2fat() and fat_time_fat2unix() functions. These unit tests verify these functions return correct output for a number of test inputs. These tests were inspored by -- and serve a similar purpose to -- the timestamp parsing KUnit tests in ext4[1]. Note that, unlike fat_time_unix2fat, fat_time_fat2unix wasn't previously exported, so this patch exports it as well. This is required for the case where we're building the fat and fat_test as modules.

[PATCH net] selftests: mptcp: depends on built-in IPv6

by Matthieu Baerts

Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6 will stay disabled and selftests will fail. We also need CONFIG_IPV6 to be built-in. For more details, please see commit 0ed37ac586c0 ("mptcp: depends on IPV6 but not as a module"). Note that 'make kselftest-merge' will take all 'config' files found in 'tools/testsing/selftests'. Because some of them already set CONFIG_IPV6=y, MPTCP selftests were still passing. But they will fail if MPTCP selftests are launched manually after having executed this command to prepare the kernel config: ./scripts/kconfig/merge_config.sh -m .config \ ./tools/testing/selftests/net/mptcp/config Fixes: 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 instead of selecting it") Signed-off-by: Matthieu Baerts <matthieu.baerts(a)tessares.net> --- tools/testing/selftests/net/mptcp/config | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/testing/selftests/net/mptcp/config b/tools/testing/selftests/net/mptcp/config index 8df5cb8f71ff..741a1c4f4ae8 100644 --- a/tools/testing/selftests/net/mptcp/config +++ b/tools/testing/selftests/net/mptcp/config @@ -1,4 +1,5 @@ CONFIG_MPTCP=y +CONFIG_IPV6=y CONFIG_MPTCP_IPV6=y CONFIG_INET_DIAG=m CONFIG_INET_MPTCP_DIAG=m -- 2.27.0

[RFC,net-next, 0/4] seg6: add support for SRv6 End.DT4 behavior

by Andrea Mayer

This patchset adds support for the SRv6 End.DT4 behavior. The SRv6 End.DT4 is used to implement multi-tenant IPv4 L3VPN. It decapsulates the received packets and performs IPv4 routing lookup in the routing table of the tenant. The SRv6 End.DT4 Linux implementation leverages a VRF device. SRv6 End.DT4 is defined in the SRv6 Network Programming [1]. - Patch 1/4 is needed to solve a pre-existing issue with tunneled packets when a sniffer is attached; - Patch 2/4 introduces two callbacks used for customizing the creation/destruction of a SRv6 behavior; - Patch 3/4 is the core patch that adds support for the SRv6 End.DT4 behavior; - Patch 4/4 adds the selftest for SRv6 End.DT4. I would like to thank David Ahern for his support during the development of this patch set. Comments, suggestions and improvements are very welcome! Thanks, Andrea Mayer [1] https://tools.ietf.org/html/draft-ietf-spring-srv6-network-programming Andrea Mayer (4): vrf: push mac header for tunneled packets when sniffer is attached seg6: add callbacks for customizing the creation/destruction of a behavior seg6: add support for the SRv6 End.DT4 behavior add selftest for the SRv6 End.DT4 behavior drivers/net/vrf.c | 78 ++- net/ipv6/seg6_local.c | 261 ++++++++++ .../selftests/net/srv6_end_dt4_l3vpn_test.sh | 490 ++++++++++++++++++ 3 files changed, 823 insertions(+), 6 deletions(-) create mode 100755 tools/testing/selftests/net/srv6_end_dt4_l3vpn_test.sh -- 2.20.1

[PATCH v2] fat: Add KUnit tests for checksums and timestamps

by David Gow

Add some basic sanity-check tests for the fat_checksum() function and the fat_time_unix2fat() and fat_time_fat2unix() functions. These unit tests verify these functions return correct output for a number of test inputs. These tests were inspored by -- and serve a similar purpose to -- the timestamp parsing KUnit tests in ext4[1]. Note that, unlike fat_time_unix2fat, fat_time_fat2unix wasn't previously exported, so this patch exports it as well. This is required for the case where we're building the fat and fat_test as modules.
