Follow the example of case-insensitive symbolic signal values in signal
and inject expressions and make symbolic errno values in inject
expressions case-insensitive.
* qualify.c (find_errno_by_name): Use strcasecmp instead of strcmp
to match symbolic errno values.
* tests/qual_fault.c (main): Likewise.
* tests/qual_fault.test: Test case-insensitive symbolic errno match.
Introduce -e inject= as a general injection option,
limit -e fault= option to syscall fault injection.
Change default return code of syscall fault injection to ENOSYS.
* qualify.c (parse_inject_token): Add fault_tokens_only argument,
do not accept retval= and signal= tokens when fault_tokens_only
is set to true.
(parse_inject_expression): Add fault_tokens_only argument,
forward it to parse_inject_token.
(qualify_inject_common): New function.
(qualify_fault): Use it.
(qualify_inject): New function.
(qual_options): New entry.
* strace.1: Describe -e inject= option.
* NEWS: Mention -e inject= option.
* tests/qual_fault-syntax.test: Test that -e fault= option does not
support retval=, signal=, and multiple error= tokens.
* tests/qual_fault.c (DEFAULT_ERRNO): Set to ENOSYS unconditionally.
* tests/qual_inject-retval.test: Replace -e fault= option
with -e inject= option.
* tests/qual_inject-syntax.test: New test.
* tests/Makefile.am (MISC_TESTS): Add it.
Rename files related to fault injection to avoid further confusion.
* tests/fault_injection-exit_group.expected: Rename
to tests/qual_fault-exit_group.expected.
* tests/fault_injection-exit_group.test: Rename
to tests/qual_fault-exit_group.test.

* tests/.gitignore: Update.
* tests/Makefile.am (check_PROGRAMS, DECODER_TESTS, MISC_TESTS,
EXTRA_DIST): Update.
As -e fault= injection syntax has been extended to configure various
kinds of injections besides fault injection, the original option name
bacame too narrow.
This change renames internal constants, types, and functions from
"fault" to more generic inject/tamper ones.
* defs.h (fault_opts): Rename to inject_opts.
(FAULT_OPTS_RVAL_DEFAULT): Rename to INJECT_OPTS_RVAL_DEFAULT.

All callers changed.
Drop local VAL_STR macro in favour of ARG_STR macro from tests/tests.h.
* tests/msg_control.c (VAL_STR): Remove.
(test_sol_socket, test_sol_ip): Replace VAL_STR with ARG_STR.
This fixes a typo in the arch_set_success for the or1k architecture.
* linux/or1k/set_error.c (arch_setsuccess): Rename to arch_set_success.
Fixes: 41d647c ("Implement success injection")
Closes: https://github.com/strace/strace/pull/6

(sys_bpf): New function.
(map_create, map_any, prog_load, obj_manage, prog_cgroup): Use it.
(main): Update expected output.
* tests/bpf.test: Use run_strace_match_diff.
Implement decoding of BPF_OBJ_PIN, BPF_OBJ_GET, BPF_PROG_ATTACH,
and BPF_PROG_DETACH commands.
* bpf.c: Include "xlat/bpf_attach_type.h".
(bpf_obj_manage, bpf_prog_attach, bpf_prog_detach): New functions.
(SYS_FUNC(bpf)): Use them.
* configure.ac: Check for union bpf_attr.bpf_fd and union
bpf_attr.attach_type.
* xlat/bpf_attach_type.in: New file.

* tests/bpf.c [HAVE_UNION_BPF_ATTR_BPF_FD] (obj_manage): New function.
[HAVE_UNION_BPF_ATTR_ATTACH_TYPE] (prog_cgroup): Likewise.
(main): Use them.
Use builtin macros provided by gcc >= 3.4 instead of sgidefs.h macros.
* configure.ac <mips>: Do not include <asm/sgidefs.h>, use _ABIO32
instead of _MIPS_SIM_ABI32, _ABIN32 instead of _MIPS_SIM_NABI32,
and _ABI64 instead of _MIPS_SIM_ABI64.
Build fix for MIPS with musl libc.
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.
* configure.ac: Replace <sgidefs.h> with <asm/sgidefs.h>.

* Makefile.am (m%_type_defs.h): Change sed regular expression to allow
arbitrary number of whitespace characters between "#" symbol
and "include" directive.
With the switch of fstatat family tests to USE_ASM_STAT variant,
there are no non-USE_ASM_STAT users left. Remove support of unused
non-USE_ASM_STAT case.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_mtim.tv_nsec.
* tests/fstatat.c (USE_ASM_STAT): Remove.
* tests/fstatx.c: Likewise.
* tests/lstatx.c: Likewise.
* tests/xstatx.c: Assume USE_ASM_STAT.
[!USE_ASM_STAT]: Remove.
Do not use glibc wrappers to call newfstatat and fstatat64.
These wrappers have various problems, e.g. they segfault on sparc64
and mips64 if BOGUS_STRUCT_STAT is not disabled, and they do wrong
conversion of timestamps on mips64.
* tests/fstatat.c (TEST_SYSCALL_INVOKE): Invoke the relevant syscall
directly.
(USE_ASM_STAT): Define.
* tests/fstatat64.c (TEST_BOGUS_STRUCT_STAT): Remove.
(STRUCT_STAT, STRUCT_STAT_STR, STRUCT_STAT_IS_STAT64): Define.
Based on patch by James Cowgill <james410@cowgill.org.uk>.
Remove all definitions of SAMPLE_SIZE that are identical to the fallback
definition in tests/xstatx.c.
* tests/fstat64.c (SAMPLE_SIZE): Remove.
* tests/lstat64.c (SAMPLE_SIZE): Remove.
* tests/stat64.c (SAMPLE_SIZE): Remove.
As ftruncate libc function and our create_sample function that calls
ftruncate both take size argument of type libc_off_t, change the type
of SAMPLE_SIZE constant to libc_off_t.
* tests/fstat.c (SAMPLE_SIZE): Cast to libc_off_t.
* tests/lstat.c (SAMPLE_SIZE): Likewise.
* tests/oldfstat.c (SAMPLE_SIZE): Likewise.

* tests/stat.c (SAMPLE_SIZE): Likewise.
* tests/xstatx.c (SAMPLE_SIZE): Likewise.
When cross-compiling, ioctlsort must obtain _IOC_* values from the
host, build's values may be incompatible.

* Makefile.am (EXTRA_DIST): Add it.
(ioctl_iocdef.i, ioctl_iocdef.h): New rules.
(ioctlsort%.o): Depend on ioctl_iocdef.h.
(CLEANFILES): Add ioctl_iocdef.h and ioctl_iocdef.i.
* ioctlsort.c: Include "ioctl_iocdef.h" instead of <linux/ioctl.h>.

If the test detects struct stat mismatch, this is likely an error
in definitions of a stat structure that might affect strace as well.
Fail the test instead of skipping it to attract more attention.
* tests/xstatx.c (main): Return 1 instead of 77
in case of struct stat mismatch.
Follow the example of strace.1 and put the description of -k option
into the output format group.
* strace.c (usage): Move description of -k option to the output
format group.
* print_sg_req_info.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* xlat/sg_scsi_reset.in: New file.
* scsi.c: Include "xlat/sg_scsi_reset.h".
(scsi_ioctl): Implement decoding of all SG_* ioctl commands.
