[PATCH net-next 00/14] selftests: forwarding: Add VRF-based tests

by Ido Schimmel

One of the nice things about network namespaces is that they allow one to easily create and test complex environments. Unfortunately, these namespaces can not be used with actual switching ASICs, as their ports can not be migrated to other network namespaces (NETIF_F_NETNS_LOCAL) and most of them probably do not support the L1-separation provided by namespaces. However, a similar kind of flexibility can be achieved by using VRFs and by looping the switch ports together. For example: br0 + vrf-h1 | vrf-h2 + +---+----+ + | | | | 192.0.2.1/24 + + + + 192.0.2.2/24 swp1 swp2 swp3 swp4 + + + + | | | | +--------+ +--------+ The VRFs act as lightweight namespaces representing hosts connected to the switch. This approach for testing switch ASICs has several advantages over the traditional method that requires multiple physical machines, to name a few: 1. Only the device under test (DUT) is being tested without noise from other system. 2. Ability to easily provision complex topologies. Testing bridging between 4-ports LAGs or 8-way ECMP requires many physical links that are not always available. With the VRF-based approach one merely needs to loopback more ports. These tests are written with switch ASICs in mind, but they can be run on any Linux box using veth pairs to emulate physical loopbacks. Changes since RFC: * Change location to net/forwarding instead of forwarding/ * Add ability to pause on failure * Add ability to pause on cleanup * Make configuration file optional * Make ping/ping6/mz configurable * Add more tc tests Ido Schimmel (7): selftests: forwarding: Add initial testing framework selftests: forwarding: Add a test for FDB learning selftests: forwarding: Add a test for flooded traffic selftests: forwarding: Add a test for basic IPv4 and IPv6 routing selftests: forwarding: Create test topology for multipath routing selftests: forwarding: Test IPv4 weighted nexthops selftests: forwarding: Test IPv6 weighted nexthops Jiri Pirko (7): selftests: forwarding: Add tc offload check helper selftests: forwarding: Add MAC get helper selftests: forwarding: Allow to get netdev interfaces names from commandline selftests: forwarding: Introduce tc flower matching tests selftests: forwarding: Introduce tc actions tests selftests: forwarding: Introduce basic tc chains tests selftests: forwarding: Introduce basic shared blocks tests tools/testing/selftests/net/forwarding/.gitignore | 1 + tools/testing/selftests/net/forwarding/README | 56 +++ .../selftests/net/forwarding/bridge_vlan_aware.sh | 87 ++++ tools/testing/selftests/net/forwarding/config | 12 + .../net/forwarding/forwarding.config.sample | 31 ++ tools/testing/selftests/net/forwarding/lib.sh | 533 +++++++++++++++++++++ tools/testing/selftests/net/forwarding/router.sh | 125 +++++ .../selftests/net/forwarding/router_multipath.sh | 317 ++++++++++++ .../testing/selftests/net/forwarding/tc_actions.sh | 195 ++++++++ .../testing/selftests/net/forwarding/tc_chains.sh | 122 +++++ .../testing/selftests/net/forwarding/tc_common.sh | 23 + .../testing/selftests/net/forwarding/tc_flower.sh | 196 ++++++++ .../selftests/net/forwarding/tc_shblocks.sh | 122 +++++ 13 files changed, 1820 insertions(+) create mode 100644 tools/testing/selftests/net/forwarding/.gitignore create mode 100644 tools/testing/selftests/net/forwarding/README create mode 100755 tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh create mode 100644 tools/testing/selftests/net/forwarding/config create mode 100644 tools/testing/selftests/net/forwarding/forwarding.config.sample create mode 100644 tools/testing/selftests/net/forwarding/lib.sh create mode 100755 tools/testing/selftests/net/forwarding/router.sh create mode 100755 tools/testing/selftests/net/forwarding/router_multipath.sh create mode 100755 tools/testing/selftests/net/forwarding/tc_actions.sh create mode 100755 tools/testing/selftests/net/forwarding/tc_chains.sh create mode 100644 tools/testing/selftests/net/forwarding/tc_common.sh create mode 100755 tools/testing/selftests/net/forwarding/tc_flower.sh create mode 100755 tools/testing/selftests/net/forwarding/tc_shblocks.sh -- 2.14.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] selftests/x86: Detect -no-pie availability

by Florian Weimer

Some toolchains need -no-pie to build all tets, others do not support the -no-pie flag at all. Therefore, add another test for the availability of the flag. This amends commit 3346a6a4e5ba8c040360f753b26938cec31a4bdc ("selftests: x86: sysret_ss_attrs doesn't build on a PIE build").

[PATCH v2 00/17] tracing: probeevent: Improve fetcharg features

by Masami Hiramatsu

Hi, This is the 2nd version of the fetch-arg improvement series. This includes variable changes on fetcharg framework like, - Add fetcharg testcases (syntax, argN, symbol, string and array) - Rewrite fetcharg framework with fetch_insn, switch-case based instead of function pointer. - Add "symbol" type support, which shows symbol+offset instead of address value. - Add "$argN" fetcharg, which fetches function parameters. (currently only for x86-64) - Add array type support (including string arrary :) ) , which enables to get fixed length array from probeevents. >From the v1, I've added many fixes and testcases. The 2 biggest change are adding many testcases and support string array. Note that the first 3 patches ([1/17] - [3/17]) can be applied independently, since those are a bugfix and testcase for existing features. The string array type (e.g. +0(%si):string[2]) is a bit different from other array types (like x16[8] etc.). For other types, <base-type>[1] is equal to <base-type> (e.g. +0(%di):x32[1] is same as +0(%di):x32.) But "string[1]" is not equal to "string". The string type itself represents "char array", but string array type represents "char * array". So, for example, +0(%di):string[1] is equal to +0(+0(%di)):string. The 1st version is here: https://www.spinics.net/lists/linux-trace/msg00583.html Here are examples: o 'symbol' type # echo 'p vfs_read $stack0:symbol' > kprobe_events # echo 1 > events/kprobes/p_vfs_read_0/enable # tail -n 3 trace sh-729 [007] ...2 105.753637: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=SyS_read+0x42/0x90 tail-736 [000] ...2 105.754904: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=kernel_read+0x2c/0x40 tail-736 [000] ...2 105.754929: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=kernel_read+0x2c/0x40 o $argN # echo 'p vfs_read $arg0 $arg1 $arg2' > kprobe_events # echo 1 > events/kprobes/p_vfs_read_0/enable # tail -n 3 trace sh-726 [007] ...2 134.288973: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffff88001d98ec00 arg2=0x7ffeb4330f79 arg3=0x1 tail-731 [000] ...2 134.289987: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffff88001d9dd200 arg2=0xffff88001d8a0a00 arg3=0x80 tail-731 [000] ...2 134.290016: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffff88001d9dd200 arg2=0xffff88001faf4a00 arg3=0x150 o Array type # echo 'p vfs_read +0($stack):x64 +0($stack):x8[8]' > kprobe_events # echo 1 > events/kprobes/p_vfs_read_0/enable # tail -n 3 trace sh-729 [007] ...2 91.701664: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffffffff811b1252 arg2={0x52,0x12,0x1b,0x81,0xff,0xff,0xff,0xff} tail-734 [000] ...2 91.702366: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffffffff811b0dec arg2={0xec,0xd,0x1b,0x81,0xff,0xff,0xff,0xff} tail-734 [000] ...2 91.702386: p_vfs_read_0: (vfs_read+0x0/0x130) arg1=0xffffffff811b0dec arg2={0xec,0xd,0x1b,0x81,0xff,0xff,0xff,0xff} # # cat events/kprobes/p_vfs_read_0/format name: p_vfs_read_0 ID: 1069 format: field:unsigned short common_type;

[PATCH] selftest: support running subset of selftests for run_kselftest.sh

by Zong Li

Simply use the first argument to specify the subset of selftests. Use comma notation to separate multiple tests. (e.g. ./run_kselftest.sh size,timers,...) Default behaviour is running all selftests. Each selftest be defined as function that we can run one of selftests. The function name has underline as prefix to avoid confilct with built-in command of shell. (e.g. The exec is built-in command of shell) The hyhpen of function name be replace to the underline because not all shells can use hyphen in function name, like sh, ash and so on.

[PATCHv2 0/2] Ion unit test with VGEM

by Laura Abbott

Hi, This is v2 of the series to add a unit test to Ion with VGEM. From v1: Ion hasn't had much in the way of unit tests and fixing that is something that needs to happen before it can move out of staging. The difficult part of testing parts of Ion is that it relies on having a kernel driver to actually make some of the dma_buf calls. The vgem DRM driver exists mostly for testing and works great for this case. Changes since v1: - Dropped RFC - Feedback/review from Daniel Vetter about DRM ioctls Thanks, Laura Laura Abbott (2): selftests: ion: Remove some prints selftests: ion: Add simple test with the vgem driver tools/testing/selftests/android/ion/Makefile | 3 +- tools/testing/selftests/android/ion/config | 1 + tools/testing/selftests/android/ion/ionmap_test.c | 149 ++++++++++++++++++++++ tools/testing/selftests/android/ion/ionutils.c | 6 - 4 files changed, 152 insertions(+), 7 deletions(-) create mode 100644 tools/testing/selftests/android/ion/ionmap_test.c -- 2.14.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] selftests/intel_pstate: Fix build rule for x86

by Daniel Díaz

Ensure that ARCH is defined and that this only builds for x86 architectures. It is possible to build from the root of the Linux tree, which will define ARCH, or to run make from the selftests/ directory itself, which has no provision for defining ARCH, so this change is to use the current definition (if any), or to check uname -m if undefined.
