2022-11-21bpf: Set and check spin lock value in sk_storage_map_testXu Kuohai1-16/+20
Update sk_storage_map_test to make sure kernel does not copy user non-zero value spin lock to kernel, and does not copy kernel spin lock value to user. If user spin lock value is copied to kernel, this test case will make kernel spin on the copied lock, resulting in rcu stall and softlockup.

2022-11-21selftests/net: Find nettest in current directoryDaniel Díaz2-8/+13
The `nettest` binary, built from `selftests/net/nettest.c`, was expected to be found in the path during test execution of `fcnal-test.sh` and `pmtu.sh`, leading to tests getting skipped when the binary is not installed in the system, as can be seen in these logs found in the wild [1]: # TEST: vti4: PMTU exceptions [SKIP] [ 350.600250] IPv6: ADDRCONF(NETDEV_CHANGE): veth_b: link becomes ready [ 350.607421] IPv6: ADDRCONF(NETDEV_CHANGE): veth_a: link becomes ready # 'nettest' command not found; skipping tests # xfrm6udp not supported # TEST: vti6: PMTU exceptions (ESP-in-UDP) [SKIP] [ 351.605102] IPv6: ADDRCONF(NETDEV_CHANGE): veth_b: link becomes ready [ 351.612243] IPv6: ADDRCONF(NETDEV_CHANGE): veth_a: link becomes ready # 'nettest' command not found; skipping tests # xfrm4udp not supported The `unicast_extensions.sh` tests also rely on `nettest`, but it runs fine there because it looks for the binary in the current working directory [2]: The same mechanism that works for the Unicast extensions tests is here copied over to the PMTU and functional tests.

2022-11-17selftests: mptcp: fix mibit vs mbit mix upMatthieu Baerts1-2/+3
The estimated time was supposing the rate was expressed in mibit (bit * 1024^2) but it is in mbit (bit * 1000^2). This makes the threshold higher but in a more realistic way to avoid false positives reported by CI instances. Before this patch, the thresholds were at 7561/4005ms and now they are at 7906/4178ms. While at it, also fix a typo in the linked comment, spotted by Mat.

Not running it from a new netns causes issues if some MPTCP settings are modified, e.g. if MPTCP is disabled from the sysctl knob, if multiple addresses are available and added to the MPTCP path-manager, etc. In these cases, the created connection will not behave as expected, e.g. unable to create an MPTCP socket, more than one subflow is seen, etc. A new "sandbox" net namespace is now created and used to run mptcp_sockopt from this controlled environment.

2022-11-18random: use random.trust_{bootloader,cpu} command line option onlyJason A. Donenfeld1-2/+0
It's very unusual to have both a command line option and a compile time option, and apparently that's confusing to people. Also, basically everybody enables the compile time option now, which means people who want to disable this wind up having to use the command line option to ensure that anyway. So just reduce the number of moving pieces and nix the compile time option in favor of the more versatile command line option. Signed-off-by: Jason A. Donenfeld <[email protected]>
2022-11-17selftests/tdx: Test TDX attestation GetReport supportKuppuswamy Sathyanarayanan4-0/+172
Attestation is used to verify the trustworthiness of a TDX guest. During the guest bring-up, the Intel TDX module measures and records the initial contents and configuration of the guest, and at runtime, guest software uses runtime measurement registers (RMTRs) to measure and record details related to kernel image, command line params, ACPI tables, initrd, etc. At guest runtime, the attestation process is used to attest to these measurements. The first step in the TDX attestation process is to get the TDREPORT data. It is a fixed size data structure generated by the TDX module which includes the above mentioned measurements data, a MAC ID to protect the integrity of the TDREPORT, and a 64-Byte of user specified data passed during TDREPORT request which can uniquely identify the TDREPORT. Intel's TDX guest driver exposes TDX_CMD_GET_REPORT0 IOCTL interface to enable guest userspace to get the TDREPORT subtype 0. Add a kernel self test module to test this ABI and verify the validity of the generated TDREPORT.

This initial code does a simple sample transfer tests. By default, all PCM devices are detected and tested with short and long buffering parameters for 4 seconds. If the sample transfer timing is not in a +-100ms boundary, the test fails. Only the interleaved buffering scheme is supported in this version. The configuration may be modified with the configuration files. A specific hardware configuration is detected and activated using the sysfs regex matching. This allows to use the DMI string (/sys/class/dmi/id/* tree) or any other system parameters exposed in sysfs for the matching for the CI automation. The configuration file may also specify the PCM device list to detect the missing PCM devices. v1..v2: - added missing alsa-local.h header file Cc: Mark Brown <[email protected]> Cc: Pierre-Louis Bossart <[email protected]> Cc: Liam Girdwood <[email protected]> Cc: Jesse Barnes <[email protected]> Cc: Jimmy Cheng-Yi Chiang <[email protected]> Cc: Curtis Malainey <[email protected]> Cc: Brian Norris <[email protected]> Signed-off-by: Jaroslav Kysela <[email protected]> Reviewed-by: Mark Brown <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Takashi Iwai <[email protected]>

2022-11-08kselftest/arm64: Provide progress messages when signalling childrenMark Brown1-0/+3

2022-11-08kselftest/arm64: Check that all children are producing output in fp-stressMark Brown1-0/+23
Currently we don't have an explicit check that when it's been a second since we have seen output produced from the test programs starting up that means all of them are running and we should start both sending signals and timing out. This is not reliable, especially on very heavily loaded systems where the test programs might take longer than a second to run. We do skip sending signals to children that have not produced output yet so we won't cause them to exit unexpectedly by sending a signal but this can create confusion when interpreting output, for example appearing to show the tests running for less time than expected or appearing to show missed signal deliveries. Avoid issues by explicitly checking that we have seen output from all the child processes before we start sending signals or counting test run time. This is especially likely on virtual platforms with large numbers of vector lengths supported since the platforms are slow and there will be a lot of tasks per CPU.

2022-11-04selftests/net: give more time to udpgro bg processes to complete startupAdrien Thierry3-4/+4
In some conditions, background processes in udpgro don't have enough time to set up the sockets. When foreground processes start, this results in the test failing with "./udpgso_bench_tx: sendmsg: Connection refused". For instance, this happens from time to time on a Qualcomm SA8540P SoC running CentOS Stream 9. To fix this, increase the time given to background processes to complete the startup before foreground processes start. Signed-off-by: Adrien Thierry <[email protected]> Signed-off-by: David S.
