* selftests: mlxsw: Add a TBF selftestPetr Machata2020-01-253-0/+27
| | | | | | | | | | | | | | Add a test that runs traffic across a port throttled with TBF. The test checks that the observed throughput is within +-5% from the installed shaper. To allow checking both the software datapath and the offloaded one, make the test suitable for inclusion from driver-specific wrapper. Introduce such wrappers for mlxsw.

* selftests: Move two functions from mlxsw's qos_lib to libPetr Machata2020-01-251-24/+0
| | | | | | | | | | | | | The function humanize() is used for converting value in bits/s to a human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing hardware-specific in that, so move the function to lib.sh. Similarly for the rate() function, which just does a bit of math to calculate a rate, given two counter values and a time interval.

| * selftests: mlxsw: qos_mc_aware: Fix mausezahn invocationPetr Machata2020-01-151-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mausezahn does not recognize "own" as a keyword on source IP address. As a result, the MC stream is not running at all, and therefore no UC degradation can be observed even in principle. Fix the invocation, and tighten the test: due to the minimum shaper configured at the MC TCs, we always expect about 20% degradation. Fail the test if it is lower.

* | selftests: forwarding: sch_ets: Add test coverage for ETS QdiscPetr Machata2019-12-182-0/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tests the newly-added ETS Qdisc. It runs two to three streams of traffic, each with a different priority. ETS Qdisc is supposed to allocate bandwidth according to the DRR algorithm and given weights. After running the traffic for a while, counters are compared for each stream to check that the expected ratio is in fact observed. In order for the DRR process to kick in, a traffic bottleneck must exist in the first place. In slow path, such bottleneck can be implemented by wrapping the ETS Qdisc inside a TBF or other shaper. This might however make the configuration unoffloadable. Instead, on HW datapath, the bottleneck would be set up by lowering port speed and configuring shared buffer suitably. Therefore the test is structured as a core component that implements the testing, with two wrapper scripts that implement the details of slow path resp. fast path configuration.

Commit 0ce1822c2a08 ("vxlan: add adjacent link to limit depth level") changed the VXLAN device to be an upper of the physical device which causes mlxsw to veto the creation of the VXLAN device with "Unknown upper device type". This is OK as this configuration is not supported, but it prevents us from testing bad flows involving the enslavement of VXLAN devices with a physical device to a bridge, regardless if the physical device is an mlxsw netdev or not. Adjust the test to use a dummy device as a physical device instead of a mlxsw netdev.

* mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel2019-09-271-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | When a port is created, its VLAN filters are not cleared by the firmware. This causes tagged packets to be later dropped by the ingress STP filters, which default to DISCARD state. The above did not matter much until commit b5ce611fd96e ("mlxsw: spectrum: Add devlink-trap support") where we exposed the drop reason to users. Without this patch, the drop reason users will see is not consistent. If a port is enslaved to a VLAN-aware bridge and a packet with an invalid VLAN tries to ingress the bridge, it will be dropped due to ingress STP filter. If the VLAN is later enabled and then disabled, the packet will be dropped by the ingress VLAN filter despite the above being a seemingly NOP operation. Fix this by clearing all the VLAN filters during port initialization. Adjust the test accordingly.

The way exit points are presented to debuggers is enhanced, ensuring all exit points are present, so debuggers don't have to disassemble rseq critical section to properly skip over them. Discussions with the glibc community is reaching a consensus of exposing a __rseq_handled symbol from glibc to coexist with rseq early adopters. Update the rseq selftest code to expose and use this symbol. Support for compiling asm goto with clang is added with the "-no-integrated-as" compiler switch, similarly to the top level kernel Makefile. - kselftest Makefile test run output refactoring and making test output TAP13 compliant from Kees Cook: This re-factors the selftest Makefiles to extract the test running logic to be reused between "run_tests" and "emit_tests", while also fixing up the test output to be TAP version 13 compliant: - added "plan" line - fixed result line syntax - moved all test output to be "# "-prefixed as TAP "diagnostic" lines The prefixing code includes a fallback mode for limited execution environments. Additionally, the plan lines are fixed for all callers of kselftest.h. * tag 'linux-kselftest-5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (25 commits) selftests: avoid KBUILD_OUTPUT dir cluttering with selftest objects selftests: drivers: Create .gitignore to include /dma-buf/udmabuf selftests: pidfd: Create .gitignore to include pidfd_test selftests: fix bpf build/test workflow regression when KBUILD_OUTPUT is set selftests: fix install target to use default install path rseq/selftests: add -no-integrated-as for clang rseq/selftests: mips: use break instruction for RSEQ_SIG rseq/selftests: powerpc code signature: generate valid instructions rseq/selftests: aarch64 code signature: handle big-endian environment rseq/selftests: arm: use udf instruction for RSEQ_SIG rseq/selftests: s390: use trap4 for RSEQ_SIG rseq/selftests: x86: use ud1 instruction as RSEQ_SIG opcode rseq/selftests: s390: use jg instruction for jumps outside of the asm rseq/selftests: Use __rseq_handled symbol to coexist with glibc rseq/selftests: Introduce __rseq_cs_ptr_array, rename __rseq_table to __rseq_cs rseq/selftests: Add __rseq_exit_point_array section for debuggers rseq/selftests: x86: Work-around bogus gcc-8 optimisation selftests: Add test plan API to kselftest.h and adjust callers selftests: Remove KSFT_TAP_LEVEL selftests: Move test output to diagnostic lines ...
