Check that syscall counters used for tampering are per-tcb.
* tests/qual_fault.c: Include <fcntl.h> for open(),
<sys/param.h> for PATH_MAX, and <sys/wait.h> for wait().
(expfd): Rename to exp_fd, remove const qualifier and initialization.
(gotfd): Rename to got_fd, remove const qualifier and initialization.
(out_fd): New variable, for the expected strace output.
(open_file): New helper function.
(main): Remove st, add num_procs, proc, exp_prefix, got_prefix,
out_prefix, pid_prefix. Remove stat asserts, update argc assert.
Add num_procs, exp_prefix, got_prefix, out_prefix, pid_prefix
initialization. Add per-process loop, open expfd, gotfd, out_fd, pidfd
in each one, print process's pid to pidfd, print exit message to out_fd.
Add wait() call for each forked process.
* tests/qual_fault.test (N): increase to 100 in order to check
concurrent process execution.
(check_fault_injection): Take additional argument for the process
count, pass it to qual_fault, add filename variables for expected strace
output and pid file, pass them to qual_fault.
Specify -ff parameter to strace invocation.
Compare write and strace output for the each process.
Update all check_fault_injection invocation with process count argument,
add an invocation with 4 concurrent processes.
* tests/init.sh (TIMEOUT_DURATION): Raise from 120 to 300.

Recently added tests based on pure_executables.list are quite slow
by their nature, the one minute default timeout is no longer enough
for some of not so fast architectures.
* tests/init.sh (TIMEOUT_DURATION): Raise from 60 to 120.
This introduces three new helpers:
prog_set_subtract subtracts one program set from another,
test_pure_prog_set runs strace check on a set of programs,
test_trace_expr tests trace expressions.
* tests/init.sh (prog_set_subtract, test_pure_prog_set,
test_trace_expr): New functions.
Workaround a bug introduced in GNU grep 2.27, for details see
https://lists.gnu.org/archive/html/bug-grep/2016-12/msg00011.html
* tests/init.sh (grep_pid_status): New function.
* tests/detach-running.test: Use it instead of grep to search
in /proc/$pid/status.
* tests/detach-sleeping.test: Likewise.
* tests/detach-stopped.test: Likewise.
* tests/init.sh (kernel_version_code,
require_min_kernel_version_or_skip): New functions.
* tests/threads-execve.test: Use require_min_kernel_version_or_skip.
This makes debugging of failing test a bit easier.
* tests/init.sh (match_grep): Add the cnt variable, increment it on every
pattern line read, print it as a prefix for non-matched pattern.
* init.sh (run_prog, run_prog_skip_if_failed): When the program fails,
add its exit code to the diagnostic message.
(run_strace): When strace fails, add its exit code to the diagnostic
message.
(run_strace_merge): When strace-log-merge fails, add its exit code
to the diagnostic message.
As virtually every test defines either one or both of OUT and ERR
variables and these definitions are exactly the same, move definitions
of these variables from individual tests to init.sh.
* tests/init.sh (OUT, ERR): New variables.
* tests/ipc.sh: Remove initialization of OUT variable.
* tests/statx.sh: Likewise.
* tests/*.test: Remove initialization of OUT and ERR variables.
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
Some of our tests use GNU awk @include extension, but not all currently
used versions of GNU awk support it. Skip these tests if gawk does not
provide @include support.
* tests/init.sh (check_gawk): New function.
(match_awk): Use it.
Factor out awk code used in several tests to match.awk.
* tests/match.awk: New file.
* tests/Makefile.am (EXTRA_DIST): Add it.
* tests/caps.awk: Use it.
* tests/getdents.awk: Likewise.
* tests/getrandom.awk: Likewise.
* tests/select.awk: Likewise.
* tests/sigaction.awk: Likewise.
* tests/init.sh (match_awk): Use gawk not awk. Define AWKPATH.
* tests/getdents.test: Likewise.
Factor out shell code used in several tests to common functions.
* tests/fanotify_mark.expected: New file.
* tests/ioctl.expected: New file.
* tests/net-fd.expected: New file.
* tests/net.expected: New file.
* tests/statfs.expected: New file.
* tests/sun_path.expected: New file.
* tests/uio.expected: New file.
* tests/ipc.sh: New file.
* tests/Makefile.am (EXTRA_DIST): Add them.
* tests/init.sh (dump_log_and_fail_with, run_prog,
run_prog_skip_if_failed, run_strace, run_strace_merge,
match_awk, match_diff, match_grep): New functions.
* tests/*.test: Use them.
Run each test using a wrapper that does all necessary timeout checks.
* tests/run.sh: New file.
* tests/Makefile.am (EXTRA_DIST, LOG_COMPILER): Add it.
* tests/init.sh (check_strace, check_timeout): Remove.
* tests/detach-stopped: Update callers.
* tests/net: Likewise.
* tests/ptrace_setoptions: Likewise.
* tests/qual_syscall: Likewise.
* tests/stat: Likewise.
* tests/strace-f: Likewise.
Busybox version of timeout doesn't have --version option.
Relax check_prog to handle those cases.
* tests/init.sh (check_prog): Use type builtin to check program
availability.
