2022-12-01kselftest/arm64: Allow epoll_wait() to return more than one resultMark Brown1-9/+18
When everything is starting up we are likely to have a lot of child processes producing output at once. This means that we can reduce overhead a bit by allowing epoll_wait() to return more than one descriptor at once, it cuts down on the number of system calls we need to do which on virtual platforms where the syscall overhead is a bit more noticable and we're likely to have a lot more children active can make a small but noticable difference. On physical platforms the relatively small number of processes being run and vastly improved speeds push the effects of this change into the noise.

2022-12-01kselftest/arm64: Hold fp-stress children until they're all spawnedMark Brown1-1/+40
At present fp-stress has a bit of a thundering herd problem since the children it spawns start running immediately, meaning that they can start starving the parent process of CPU before it has even started all the children. This is much more severe on virtual platforms since they tend to support far more SVE and SME vector lengths, be slower in general and for some have issues with performance when simulating multiple CPUs. We can mitigate this problem by having all the child processes block before starting the test program, meaning that we at least have all the child processes started before we start heavily using CPU. We still have the same load issues while waiting for the actual stress test programs to start up and produce output but they're at least all ready to go before that kicks in, resulting in substantial reductions in overall runtime on some of the severely affected systems. One test was showing about 20% improvement.

2022-11-30selftests/tpm2: Split async tests call to separate shell script runnerNícolas F. R. A. Prado3-2/+11
When the async test case was introduced, despite being a completely independent test case, the command to run it was added to the same shell script as the smoke test case. Since a shell script implicitly returns the error code from the last run command, this effectively caused the script to only return as error code the result from the async test case, hiding the smoke test result (which could then only be seen from the python unittest logs). Move the async test case call to its own shell script runner to avoid the aforementioned issue. This also makes the output clearer to read, since each kselftest KTAP result now matches with one python unittest report. While at it, also make it so the async test case is skipped if /dev/tpmrm0 doesn't exist, since commit 8335adb8f9d3 ("selftests: tpm: add async space test with noneexisting handle") added a test that relies on it.

2022-11-29ipv4: Fix route deletion when nexthop info is not specifiedIdo Schimmel1-0/+11
When the kernel receives a route deletion request from user space it tries to delete a route that matches the route attributes specified in the request. If only prefix information is specified in the request, the kernel should delete the first matching FIB alias regardless of its associated FIB info. However, an error is currently returned when the FIB info is backed by a nexthop object: # ip nexthop add id 1 via 192.0.2.2 dev dummy10 # ip route add 198.51.100.0/24 nhid 1 # ip route del 198.51.100.0/24 RTNETLINK answers: No such process Fix by matching on such a FIB info when legacy nexthop attributes are not specified in the request. An earlier check already covers the case where a nexthop ID is specified in the request. Add tests that cover these flows. Before the fix: # ./fib_nexthops.sh -t ipv4_fcnal ... TEST: Delete route when not specifying nexthop attributes [FAIL] Tests passed: 11 Tests failed: 1 After the fix: # ./fib_nexthops.sh -t ipv4_fcnal ...

2022-11-18selftests: 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.

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 <Jason@zx2c4.com>
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.
