[Linux-kselftest-mirror] [PATCH v10 00/24] selftests, powerpc, x86 : Memory Protection Keys

by Ram Pai

Memory protection keys enable applications to protect its address space from inadvertent access from itself. This feature is now enabled on powerpc architecture. The patches move the selftests to arch neutral directory and enhances them. Verified for correctness on powerpc and on x86 architectures(using EC2 ubuntu VM instances). Ram Pai (21): selftests/x86: Move protecton key selftest to arch neutral directory selftests/vm: rename all references to pkru to a generic name selftests/vm: move generic definitions to header file selftests/vm: typecast the pkey register selftests/vm: generic function to handle shadow key register selftests/vm: fix the wrong assert in pkey_disable_set() selftests/vm: fixed bugs in pkey_disable_clear() selftests/vm: clear the bits in shadow reg when a pkey is freed. selftests/vm: fix alloc_random_pkey() to make it really random selftests/vm: introduce two arch independent abstraction selftests/vm: pkey register should match shadow pkey selftests/vm: generic cleanup selftests/vm: powerpc implementation for generic abstraction selftests/vm: clear the bits in shadow reg when a pkey is freed. selftests/vm: powerpc implementation to check support for pkey selftests/vm: fix an assertion in test_pkey_alloc_exhaust() selftests/vm: associate key on a mapped page and detect access violation selftests/vm: associate key on a mapped page and detect write violation selftests/vm: detect write violation on a mapped access-denied-key page selftests/vm: testcases must restore pkey-permissions selftests/vm: sub-page allocator Thiago Jung Bauermann (3): selftests/vm: Fix deadlock in protection_keys.c selftests/powerpc: Add ptrace tests for Protection Key register selftests/powerpc: Add core file test for Protection Key register tools/testing/selftests/powerpc/include/reg.h | 1 + tools/testing/selftests/powerpc/ptrace/Makefile | 5 +- tools/testing/selftests/powerpc/ptrace/core-pkey.c | 438 ++++++ .../testing/selftests/powerpc/ptrace/ptrace-pkey.c | 443 ++++++ tools/testing/selftests/vm/Makefile | 1 + tools/testing/selftests/vm/pkey-helpers.h | 419 ++++++ tools/testing/selftests/vm/protection_keys.c | 1471 ++++++++++++++++++++ tools/testing/selftests/x86/Makefile | 2 +- tools/testing/selftests/x86/pkey-helpers.h | 223 --- tools/testing/selftests/x86/protection_keys.c | 1407 ------------------- 10 files changed, 2778 insertions(+), 1632 deletions(-) create mode 100644 tools/testing/selftests/powerpc/ptrace/core-pkey.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-pkey.c create mode 100644 tools/testing/selftests/vm/pkey-helpers.h create mode 100644 tools/testing/selftests/vm/protection_keys.c delete mode 100644 tools/testing/selftests/x86/pkey-helpers.h delete mode 100644 tools/testing/selftests/x86/protection_keys.c -- 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

[Linux-kselftest-mirror] [RFC PATCH net-next 00/12] 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. Feedback is is welcome. Particularly regarding the best location for these tests (e.g., current location, tools/testing/selftests/net). Thanks. 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 (5): 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: Allow to pass commandline options selftests: forwarding: Introduce tc flower matching tests tools/testing/selftests/Makefile | 1 + tools/testing/selftests/forwarding/.gitignore | 1 + tools/testing/selftests/forwarding/Makefile | 6 + tools/testing/selftests/forwarding/README | 56 +++ tools/testing/selftests/forwarding/bridge.sh | 117 +++++++ tools/testing/selftests/forwarding/config | 12 + .../selftests/forwarding/forwarding.config.sample | 19 + tools/testing/selftests/forwarding/lib.sh | 383 +++++++++++++++++++++ tools/testing/selftests/forwarding/router.sh | 131 +++++++ .../selftests/forwarding/router_multipath.sh | 321 +++++++++++++++++ tools/testing/selftests/forwarding/tc_flower.sh | 261 ++++++++++++++ 11 files changed, 1308 insertions(+) create mode 100644 tools/testing/selftests/forwarding/.gitignore create mode 100644 tools/testing/selftests/forwarding/Makefile create mode 100644 tools/testing/selftests/forwarding/README create mode 100755 tools/testing/selftests/forwarding/bridge.sh create mode 100644 tools/testing/selftests/forwarding/config create mode 100644 tools/testing/selftests/forwarding/forwarding.config.sample create mode 100644 tools/testing/selftests/forwarding/lib.sh create mode 100755 tools/testing/selftests/forwarding/router.sh create mode 100755 tools/testing/selftests/forwarding/router_multipath.sh create mode 100755 tools/testing/selftests/forwarding/tc_flower.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

[Linux-kselftest-mirror] [PATCH v2] selftest: support run subset of selftests when running installed selftests

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 installed. 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) Replace the hyphen with underline for cpu-hotplug and memory-hotplug. Not all shell can use hyphen in function name, like sh, ash and so on.
