2018-03-14selftests/x86/entry_from_vm86: Add test cases for POPFAndy Lutomirski1-3/+27
POPF is currently broken -- add tests to catch the error. This results in: [RUN] POPF with VIP set and IF clear from vm86 mode [INFO] Exited vm86 mode due to STI [FAIL] Incorrect return reason (started at eip = 0xd, ended at eip = 0xf) because POPF currently fails to check IF before reporting a pending interrupt. This patch also makes the FAIL message a bit more informative.

2018-03-13selftests/powerpc: Skip tm-unavailable if TM is not enabledGustavo Romero1-8/+16
Some processor revisions do not support transactional memory, and additionally kernel support can be disabled. In either case the tm-unavailable test should be skipped, otherwise it will fail with a SIGILL. That commit also sets this selftest to be called through the test harness as it's done for other TM selftests. Finally, it avoids using "ping" as a thread name since it's ambiguous and can be confusing when shown, for instance, in a kernel backtrace log.

2018-03-08x86/vsyscall/64: Drop "native" vsyscallsAndy Lutomirski1-5/+6
Since Linux v3.2, vsyscalls have been deprecated and slow. From v3.2 on, Linux had three vsyscall modes: "native", "emulate", and "none". "emulate" is the default. All known user programs work correctly in emulate mode, but vsyscalls turn into page faults and are emulated. This is very slow. In "native" mode, the vsyscall page is easily usable as an exploit gadget, but vsyscalls are a bit faster -- they turn into normal syscalls. (This is in contrast to vDSO functions, which can be much faster than syscalls.) In "none" mode, there are no vsyscalls. For all practical purposes, "native" was really just a chicken bit in case something went wrong with the emulation. It's been over six years, and nothing has gone wrong. Delete it.

When you load nfit_test you currently see the following error in dmesg: nfit_test nfit_test.0: found a zero length table '0' parsing nfit This happens because when we parse the nfit_test.0 table via acpi_nfit_init(), we specify a size of nfit_test->nfit_size. For the first pass through nfit_test.0 where (t->setup_hotplug == 0) this is the size of the entire buffer we allocated, including space for the hot plug structures, not the size that we've actually filled in.

Also add some WARN_ON()s to nfit_test0_setup() and nfit_test1_setup() to catch future issues where the size of the buffer doesn't match the amount of data we're writing.

2018-03-06nfit_test: improve structure offset handlingRoss Zwisler1-74/+109
In nfit_test0_setup() and nfit_test1_setup() we keep an 'offset' value which we use to calculate where in our 'nfit_buf' we will place our next structure. The handling of 'offset' and the calculation of the placement of the next structure is a bit inconsistent, though. We don't update 'offset' after we insert each structure, sometimes causing us to update it for multiple structures' sizes at once. When calculating the position of the next structure we aren't always able to just use 'offset', but sometimes have to add in other structure sizes as well. Fix this by updating 'offset' after each structure insertion in a consistent way, allowing us to always calculate the position of the next structure to be inserted by just using 'nfit_buf + offset'.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-03-03 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Extend bpftool to build up CFG information of eBPF programs and add an option to dump this in DOT format such that this can later be used with DOT graphic tools (xdot, graphviz, etc) to visualize it. Part of the analysis performed is sub-program detection and basic-block partitioning, from Jiong. 2) Multiple enhancements for bpftool's batch mode, more specifically the parser now understands comments (#), continuation lines (\), and arguments enclosed between quotes. Also, allow to read from stdin via '-' as input file, all from Quentin. 3) Improve BPF kselftests by i) unifying the rlimit handling into a helper that is then used by all tests, and ii) add support for testing tail calls to test_verifier plus add tests covering all corner cases. The latter is especially useful for testing JITs, from Daniel. 4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop on x64, from Daniel. 5) Fix one more occasion in BPF samples where we do not detach the BPF program from the cgroup after completion, from Prashant. ==================== Signed-off-by: David S.

Commit 16c513b13477 ("selftests: memory-hotplug: silence test command echo") introduced regression in emit_tests and results in the following failure when selftests are installed and run. Fix it.

Daniel Borkmann says: ==================== pull-request: bpf 2018-02-28 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Add schedule points and reduce the number of loop iterations the test_bpf kernel module is performing in order to not hog the CPU for too long, from Eric. 2) Fix an out of bounds access in tail calls in the ppc64 BPF JIT compiler, from Daniel. 3) Fix a crash on arm64 on unaligned BPF xadd operations that could be triggered via interpreter and JIT, from Daniel. Please not that once you merge net into net-next at some point, there is a minor merge conflict in test_verifier.c since test cases had been added at the end in both trees. Resolution is trivial: keep all the test cases from both trees. ==================== Signed-off-by: David S. Miller <[email protected]>

On Debian jessie ping can not handle IPv6 addresses so the command fails. Use PING6 which is set to ping6. Signed-off-by: David Ahern <[email protected]> Reviewed-by: Ido Schimmel <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2018-03-01selftests: forwarding: Only check tc version for tc testsDavid Ahern7-15/+25
Capabilities of tc command are irrelevant for router tests: $ ./router.sh SKIP: iproute2 too old, missing shared block support Add a CHECK_TC flag and only check tc capabilities if set. Add flag to tc_common.sh and have it sourced before lib.sh Also, if the command lacks some feature the test should exit non-0. Signed-off-by: David Ahern <[email protected]> Signed-off-by: David S.

2018-03-02selftests/powerpc: Skip the subpage_prot tests if the syscall is unavailableMichael Ellerman1-0/+14
The subpage_prot syscall is only functional when the system is using the Hash MMU. Since commit 5b2b80714796 ("powerpc/mm: Invalidate subpage_prot() system call on radix platforms") it returns ENOENT when the Radix MMU is active. Currently this just makes the test fail. Additionally the syscall is not available if the kernel is built with 4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns ENOSYS because the syscall is missing entirely. So check explicitly for ENOENT and ENOSYS and skip if we see either of those. Signed-off-by: Michael Ellerman <[email protected]>
