[PATCH] selftests/harness: Add 30 second timeout per test

by Kees Cook

In order to keep tests from hanging forever, this adds an alarm signal to each test run. This assumes an individual test doesn't take longer than 30 seconds.

[PATCH v3 bpf-next 0/4] L2 encap support for bpf_skb_adjust_room

by Alan Maguire

Extend bpf_skb_adjust_room growth to mark inner MAC header so that L2 encapsulation can be used for tc tunnels. Patch #1 extends the existing test_tc_tunnel to support UDP encapsulation; later we want to be able to test MPLS over UDP and MPLS over GRE encapsulation. Patch #2 adds the BPF_F_ADJ_ROOM_ENCAP_L2(len) macro, which allows specification of inner mac length. Other approaches were explored prior to taking this approach. Specifically, I tried automatically computing the inner mac length on the basis of the specified flags (so inner maclen for GRE/IPv4 encap is the len_diff specified to bpf_skb_adjust_room minus GRE + IPv4 header length for example). Problem with this is that we don't know for sure what form of GRE/UDP header we have; is it a full GRE header, or is it a FOU UDP header or generic UDP encap header? My fear here was we'd end up with an explosion of flags. The other approach tried was to support inner L2 header marking as a separate room adjustment, i.e. adjust for L3/L4 encap, then call bpf_skb_adjust_room for L2 encap. This can be made to work but because it imposed an order on operations, felt a bit clunky. Patch #3 syncs tools/ bpf.h. Patch #4 extends the tests again to support MPLSoverGRE, MPLSoverUDP, and transparent ethernet bridging (TEB) where the inner L2 header is an ethernet header. Testing of BPF encap against tunnels is done for cases where configuration of such tunnels is possible (MPLSoverGRE[6], MPLSoverUDP, gre[6]tap), and skipped otherwise. Testing of BPF encap/decap is always carried out. Changes since v2: - updated tools/testing/selftest/bpf/config with FOU/MPLS CONFIG variables (patches 1, 4) - reduced noise in patch 1 by avoiding unnecessary movement of code - eliminated inner_mac variable in bpf_skb_net_grow (patch 2) Changes since v1: - fixed formatting of commit references. - BPF_F_ADJ_ROOM_FIXED_GSO flag enabled on all variants (patch 1) - fixed fou6 options for UDP encap; checksum errors observed were due to the fact fou6 tunnel was not set up with correct ipproto options (41 -6). 0 checksums work fine (patch 1) - added definitions for mask and shift used in setting L2 length (patch 2) - allow udp encap with fixed GSO (patch 2) - changed "elen" to "l2_len" to be more descriptive (patch 4) Alan Maguire (4): selftests_bpf: extend test_tc_tunnel for UDP encap bpf: add layer 2 encap support to bpf_skb_adjust_room bpf: sync bpf.h to tools/ for BPF_F_ADJ_ROOM_ENCAP_L2 selftests_bpf: add L2 encap to test_tc_tunnel include/uapi/linux/bpf.h | 10 + net/core/filter.c | 12 +- tools/include/uapi/linux/bpf.h | 10 + tools/testing/selftests/bpf/config | 8 + tools/testing/selftests/bpf/progs/test_tc_tunnel.c | 321 +++++++++++++++++---- tools/testing/selftests/bpf/test_tc_tunnel.sh | 136 +++++++-- 6 files changed, 417 insertions(+), 80 deletions(-) -- 1.8.3.1

secomp_bpf test hangs after global.user_notification_sibling_pid_ns

by shuah

Hi Kees, secomp_bpf test hangs after global.user_notification_sibling_pid_ns when a non-root user runs it on 5.1-rc4 I thought you fixed the problem with this commit: commit 3d244c192afeee7dd4f5fb1b916ea4e47420d401 Author: Kees Cook <keescook(a)chromium.org> Date: Wed Jan 16 16:35:25 2019 -0800 selftests/seccomp: Abort without user notification support seccomp_bpf.c:3380:global.user_notification_sibling_pid_ns:Expected unshare(CLONE_NEWPID) (18446744073709551615) == 0 (0) seccomp_bpf.c:3381:global.user_notification_sibling_pid_ns:Expected errno (1) == 0 (0) seccomp_bpf.c:3365:global.user_notification_sibling_pid_ns:Expected unshare(CLONE_NEWPID) (18446744073709551615) == 0 (0) seccomp_bpf.c:3392:global.user_notification_sibling_pid_ns:Expected req.pid (23610) == 0 (0) hangs right after the above message, root: [ RUN ] global.user_notification_sibling_pid_ns [ OK ] global.user_notification_sibling_pid_ns [ RUN ] global.user_notification_fault_recv [ OK ] global.user_notification_fault_recv [ RUN ] global.seccomp_get_notif_sizes [ OK ] global.seccomp_get_notif_sizes [==========] 74 / 74 tests passed. [ PASSED ] I would debug this myself, double edged sword of harness, makes it hard to debug:) Can you take a look. "make kselftest" just hangs now and doesn't complete. thanks, -- Shuah

[PATCH] selftests/lib.mk: Move test output to diagnostic lines

by Kees Cook

This changes the selftest output is several ways: - total test count is reported at start. - each test's result is on a single line with "# SKIP" as needed per spec. - each test's output is prefixed with "# " as a "diagnostic line". This creates a bit of a kernel-specific TAP dialect where the diagnostics precede the results. The TAP spec isn't entirely clear about this, though, so I think it's the correct solution so as to keep interactive runs making sense. If the output _followed_ the result line in the spec-suggested YAML form, each test would dump all of its output at once instead of as it went, making debugging harder. This does, however, solve the recursive TAP output problem, as sub-tests will simply be prefixed by "# ". Parsing sub-tests becomes a simple problem of just removing the first two characters of a given top-level test's diagnostic output, and parsing the results. Note that the shell construct needed to both get an exit code from the first command in a pipe and still filter the pipe (to add the "# " prefix) uses a POSIX solution rather than the bash "pipefail" option which is not supported by dash. Example: $ tools/testing/selftests $ make --silent -C x86 run_tests TAP version 13 1..15 selftests: x86 # selftests: x86: single_step_syscall_64 # [RUN] Set TF and check nop # [OK] Survived with TF set and 9 traps # [RUN] Set TF and check syscall-less opportunistic sysret # [OK] Survived with TF set and 12 traps # [RUN] Set TF and check a fast syscall # [OK] Survived with TF set and 22 traps # [RUN] Fast syscall with TF cleared # [OK] Nothing unexpected happened ok 1 selftests: x86: single_step_syscall_64 # selftests: x86: sysret_ss_attrs_64 # [RUN] Syscalls followed by SS validation # [OK] We survived ok 2 selftests: x86: sysret_ss_attrs_64 # selftests: x86: syscall_nt_64 # [RUN] Set NT and issue a syscall # [OK] The syscall worked and flags are still set # [RUN] Set NT|TF and issue a syscall # [OK] The syscall worked and flags are still set ok 3 selftests: x86: syscall_nt_64 ...[skipping example output]... ok 15 selftests: x86: sysret_rip_64 $ make --silent -C x86 run_tests | tappy ............F.. ====================================================================== FAIL: <file=stream> selftests: x86: mov_ss_trap_64 ---------------------------------------------------------------------- ---------------------------------------------------------------------- Ran 15 tests in 0.000s FAILED (failures=1) Signed-off-by: Kees Cook <keescook(a)chromium.org> --- No longer RFC! :) --- tools/testing/selftests/lib.mk | 59 ++++++++++++++++++------------- tools/testing/selftests/prefix.pl | 23 ++++++++++++ 2 files changed, 57 insertions(+), 25 deletions(-) create mode 100755 tools/testing/selftests/prefix.pl diff --git a/tools/testing/selftests/lib.mk b/tools/testing/selftests/lib.mk index 8b0f16409ed7..d3267c08a7b1 100644 --- a/tools/testing/selftests/lib.mk +++ b/tools/testing/selftests/lib.mk @@ -5,6 +5,8 @@ CC := $(CROSS_COMPILE)gcc ifeq (0,$(MAKELEVEL)) OUTPUT := $(shell pwd) endif +testname = $(notdir $(shell pwd)) +selfdir = $(realpath $(dir $(filter %/lib.mk,$(MAKEFILE_LIST)))) # The following are built by lib.mk common compile rules. # TEST_CUSTOM_PROGS should be used by tests that require @@ -32,38 +34,45 @@ endif .ONESHELL: define RUN_TEST_PRINT_RESULT - TEST_HDR_MSG="selftests: "`basename $$PWD`:" $$BASENAME_TEST"; \ - echo $$TEST_HDR_MSG; \ - echo "========================================"; \ + TEST_HDR_MSG="selftests: $(testname): $$BASENAME_TEST"; \ if [ ! -x $$TEST ]; then \ - echo "$$TEST_HDR_MSG: Warning: file $$BASENAME_TEST is not executable, correct this.";\ - echo "not ok 1..$$test_num $$TEST_HDR_MSG [FAIL]"; \ - else \ - cd `dirname $$TEST` > /dev/null; \ - if [ "X$(summary)" != "X" ]; then \ - (./$$BASENAME_TEST > /tmp/$$BASENAME_TEST 2>&1 && \ - echo "ok 1..$$test_num $$TEST_HDR_MSG [PASS]") || \ - (if [ $$? -eq $$skip ]; then \ - echo "not ok 1..$$test_num $$TEST_HDR_MSG [SKIP]"; \ - else echo "not ok 1..$$test_num $$TEST_HDR_MSG [FAIL]"; \ - fi;) \ - else \ - (./$$BASENAME_TEST && \ - echo "ok 1..$$test_num $$TEST_HDR_MSG [PASS]") || \ - (if [ $$? -eq $$skip ]; then \ - echo "not ok 1..$$test_num $$TEST_HDR_MSG [SKIP]"; \ - else echo "not ok 1..$$test_num $$TEST_HDR_MSG [FAIL]"; \ - fi;) \ - fi; \ - cd - > /dev/null; \ + if [ "X$(summary)" = "X" ]; then \ + echo "# warning: 'file $$TEST is not executable, correct this.'";\ + fi; \ + echo "not ok $$test_num $$TEST_HDR_MSG"; \ + else \ + cd `dirname $$TEST` > /dev/null; \ + if [ "X$(summary)" != "X" ]; then \ + (./$$BASENAME_TEST > /tmp/$$BASENAME_TEST 2>&1 &&\ + echo "ok $$test_num $$TEST_HDR_MSG") || \ + (if [ $$? -eq $$skip ]; then \ + echo "not ok $$test_num $$TEST_HDR_MSG # SKIP"; \ + else \ + echo "not ok $$test_num $$TEST_HDR_MSG";\ + fi); \ + else \ + echo "# $$TEST_HDR_MSG"; \ + (((((stdbuf -i0 -o0 -e0 ./$$BASENAME_TEST 2>&1; echo $$? >&3) | \ + $(selfdir)/prefix.pl >&4) 3>&1) | \ + (read xs; exit $$xs)) 4>&1 && \ + echo "ok $$test_num $$TEST_HDR_MSG") || \ + (if [ $$? -eq $$skip ]; then \ + echo "not ok $$test_num $$TEST_HDR_MSG # SKIP"; \ + else \ + echo "not ok $$test_num $$TEST_HDR_MSG";\ + fi); \ + fi; \ + cd - > /dev/null; \ fi; endef define RUN_TESTS @export KSFT_TAP_LEVEL=`echo 1`; \ - test_num=`echo 0`; \ - skip=`echo 4`; \ + test_num=0; \ + total=`echo "$(1)" | wc -w`; \ + skip=4; \ echo "TAP version 13"; \ + echo "1..$$total selftests: $(testname)"; \ for TEST in $(1); do \ BASENAME_TEST=`basename $$TEST`; \ test_num=`echo $$test_num+1 | bc`; \ diff --git a/tools/testing/selftests/prefix.pl b/tools/testing/selftests/prefix.pl new file mode 100755 index 000000000000..ec7e48118183 --- /dev/null +++ b/tools/testing/selftests/prefix.pl @@ -0,0 +1,23 @@ +#!/usr/bin/perl +# SPDX-License-Identifier: GPL-2.0 +# Prefix all lines with "# ", unbuffered.

[PATCH] kselftest/lkdtm: Create selftest driving scripts for LKDTM

by Kees Cook

This adds most of the non-system-crashing selftests that exist in LKDTM. The ones that leave the system in an unstable state are marked as "SKIP" in the test run. Since output can change based on architecture and other kernel configs, all output is reported during the tests. Example output: # cd tools/testing/selftests # make --silent -C lkdtm run_tests TAP version 13 1..64 selftests: lkdtm # selftests: lkdtm: PANIC.sh # PANIC: crashes entire system [SKIP] not ok 1 selftests: lkdtm: PANIC.sh # SKIP # selftests: lkdtm: BUG.sh # [19716.955023] lkdtm: Performing direct entry BUG # [19716.956236] ------------[ cut here ]------------ # [19716.957318] kernel BUG at drivers/misc/lkdtm/bugs.c:63! ... # BUG: saw 'call trace:': ok ok 2 selftests: lkdtm: BUG.sh ...

[PATCH] selftests: cgroup: fix cleanup path in test_memcg_subtree_control()

by Roman Gushchin

Dan reported, that cleanup path in test_memcg_subtree_control() triggers a static checker warning: ./tools/testing/selftests/cgroup/test_memcontrol.c:76 \ test_memcg_subtree_control() error: uninitialized symbol 'child2'. Fix this by initializing child2 and parent2 variables and split the cleanup path into few stages.
