selftest/seccomp: Fix the flag name SECCOMP_FILTER_FLAG_TSYNC

2016-03-29T19:01:28+00:00

Rename SECCOMP_FLAG_FILTER_TSYNC to SECCOMP_FILTER_FLAG_TSYNC to match
the UAPI.

selftests: create test-specific kconfig fragments

2016-02-25T16:47:52+00:00

Create the config file in each directory of testcase which need
more kernel configuration than the default defconfig. User could
use these configs with merge_config.sh script:

Enable config for specific testcase:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
		tools/testing/selftests/xxx/config

Enable configs for all testcases:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
		tools/testing/selftests/*/config

selftests/seccomp: Remove the need for HAVE_ARCH_TRACEHOOK

2016-01-10T20:49:49+00:00

Some architectures do not implement PTRACE_GETREGSET nor
PTRACE_SETREGSET (required by HAVE_ARCH_TRACEHOOK) but only implement
PTRACE_GETREGS and PTRACE_SETREGS (e.g. User-mode Linux).

This improve seccomp selftest portability for architectures without
HAVE_ARCH_TRACEHOOK support by defining a new trigger HAVE_GETREGS. For
now, this is only enabled for i386 and x86_64 architectures. This is
required to be able to run this tests on User-mode Linux.

selftests/seccomp: fix 32-bit build warnings

2016-01-07T20:40:20+00:00

The casting was done incorrectly for 32-bit builds. Fixed to use uintptr_t.

selftests/seccomp: Get page size from sysconf

2015-11-18T23:56:53+00:00

The commit fd88d16c58c2 ("selftests/seccomp: Be more precise with
syscall arguments.") use PAGE_SIZE directly which lead to build
failure on arm64.

Replace it with generic interface(sysconf(_SC_PAGESIZE)) to fix this
failure.

Build and test successful on x86_64 and arm64.

selftests/seccomp: Be more precise with syscall arguments.

2015-11-02T21:41:02+00:00

Certain syscall emulation layers strictly check that the number of
arguments match what the syscall handler expects. The KILL_one_arg_one and
KILL_one_arg_six tests passed more parameters than expected to various
syscalls, causing failures in this emulation mode. Instead, test using
syscalls that take the appropriate number of arguments.

selftests/seccomp: build and pass on arm64

2015-10-16T02:06:27+00:00

Changing arm64 syscalls is done via a specific register set, more like s390
than like arm (specific ptrace call) and x86 (part of general registers).
Since (restarting) poll doesn't exist on arm64, switch to using nanosleep
for testing restart_syscall. And since it looks like the syscall ABI is
inconsistent on arm-compat, so we must work around it (and document it) in
the test.

selftests/seccomp: add support for s390

2015-09-14T22:41:37+00:00

This adds support for s390 to the seccomp selftests. Some improvements
were made to enhance the accuracy of failure reporting, and additional
tests were added to validate assumptions about the currently traced
syscall. Also adds early asserts for running on older kernels to avoid
noise when the seccomp syscall is not implemented.
