While we are here, let's refactor the condition for old_mmap_pgoff into
an arch-specific one, as it is used more than in one place.

Because some architectures are very, very special.
* configure.ac (cc_flags_m32, cc_flags_mx32): New variables. AC_SUBST
them.
* m4/mpers.m4 (MPERS_CFLAGS): Use instead of CFLAG, pushdef as
$cc_flags_$1.
Use mpers_name instead of CFLAG in AC_CACHE_CHECK messages.
Pass MPERS_CFLAGS as the second argument to mpers_test.sh

Since there is possibility now that strace read only entry_number field
of the user_desc struct, let's check that it doesn't do it with
modify_ldt syscall.
* tests/modify_ldt.c (main): Add 4-byte-sized tail_alloc'ed variable.
Try to provide it as an argument to modify_ldt.
As part of preparation for the introduction of [gs]et_thread_area test.

* tests/print_user_desc.c: ... to new file.
* tests/Makefile.am (EXTRA_DIST): Add print_user_desc.c.
Starting with commit v4.5.19~88 strace imposed an artificial limit
on output file names in -ff mode, leading to the following absurd
behaviour:
$ strace -ff -o"$(perl -e 'print "/" x 510')/$PWD/log" /bin/true
strace: Can't fopen '////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////.12345': Permission denied

(init) <followfork >= 2>: Check output file name prefix length.
* tests/options-syntax.test: Check it.
* tests/run.sh: Execute timeout command only when invoked with
an argument, otherwise print an error message.

As linux kernel provides a compatible mtd/mtd-abi.h header since
commit v3.2-rc1~14^2~33, there is no need for a local copy.
* linux/mtd-abi.h: Remove.
* Makefile.am (EXTRA_DIST): Remove it.
* configure.ac (AC_CHECK_TYPES): Check for struct mtd_write_req
in <mtd/mtd-abi.h>.
* ioctl.c (ioctl_decode) <case 'M'>: Conditionalize
on [HAVE_STRUCT_MTD_WRITE_REQ].
* mtd.c: Likewise.
* tests/ioctl_mtd.c: Likewise.
* tests/ioctl.c (main): Likewise.
From time to time various kernels, old and new, just go nuts
and fail attach-p-cmd.test with the following diagnostics:
12345 --- SIGALRM {si_signo=SIGALRM, si_code=SI_KERNEL} ---
-12345 chdir("attach-p-cmd.test -p") = -1 ENOENT (No such file or directory)
+12345 syscall_4294967295(0xffe60934, 0x1c0, 0xffe60934, 0x1, 0xffe609b4, 0xffe60a58) = -1 (errno 38)
+12345 chdir("attach-p-cmd.test -p") = -1 ENOSYS (Function not implemented)
Let's workaround this kernel madness by rewriting the test
without use of SIGALRM.
* tests/attach-p-cmd.h: New file.
* tests/Makefile.am (EXTRA_DIST): Add attach-p-cmd.h.
* tests/attach-p-cmd-cmd.c: Include "attach-p-cmd.h".
(write_pidfile, wait_for_peer_invocation): New functions.
(main): Use them.
* tests/attach-p-cmd-p.c: Include <time.h> and "attach-p-cmd.h".
(wait_for_peer_invocation, wait_for_peer_termination): New functions.
(main): Use them. Do not raise SIGALRM, use nanosleep after peer
termination.
glibc between commits glibc-2.25~130 and glibc-2.26~740 had broken
msgctl(IPC_RMID) on hppa: this operation always failed with EINVAL
because of inappropriate use of IPC_64 flag. Similar issues were
fixed on other niche architectures. Let's workaround these issues
by skipping the test in case of msgctl(IPC_RMID) failure.
* tests/ipc_msgbuf.c (cleanup): Change return type to int,
return 77 in case of msgctl(IPC_RMID) failure.
(main): Explicitly invoke cleanup() at the end.
* tests/bpf.c (DEF_BPF_INIT_FIRST): New macro.
(init_BPF_MAP_CREATE_first, init_BPF_MAP_LOOKUP_ELEM_first,
init_BPF_PROG_LOAD_first, init_BPF_OBJ_PIN_first,
init_BPF_PROG_ATTACH_first, init_BPF_PROG_TEST_RUN_first,
init_BPF_PROG_GET_NEXT_ID_first, init_BPF_OBJ_GET_INFO_BY_FD_first):
Use it.
* configure.ac: Check for union bpf_attr.test.duration.
* bpf.c (decode_BPF_PROG_TEST_RUN): New function.
(SYS_FUNC(bpf)) <bpf_cmd_decoders>: Use it.
* NEWS: Mention this.
* tests/bpf.c: Include "print_fields.h".
Add macro guard for BPF_PROG_TEST_RUN decoder test.
[HAVE_UNION_BPF_ATTR_TEST_DURATION] (sample_BPF_PROG_TEST_RUN_attr):
New variable.
[HAVE_UNION_BPF_ATTR_TEST_DURATION] (init_BPF_PROG_TEST_RUN_first,
print_BPF_PROG_TEST_RUN_first, init_BPF_PROG_TEST_RUN_attr,
print_BPF_PROG_TEST_RUN_attr): New functions.
(main) [HAVE_UNION_BPF_ATTR_TEST_DURATION]: Use them.
Implement decoding of union bpf_attr.numa_node field for BPF_MAP_CREATE
command introduced by linux kernel commit v4.14-rc1~130^2~196^2~1.
* configure.ac: Check for numa_node member of union bpf_attr
instead of inner_map_fd.
(decode_BPF_MAP_CREATE): Add numa_node field to the structure, print it.
* NEWS: Mention this.
* tests/bpf.c: Update macro guards of BPF_MAP_CREATE decoder test.
(init_BPF_MAP_CREATE_first, print_BPF_MAP_CREATE_attr): Update expected
output.
(init_BPF_MAP_CREATE_attr): Initialize numa_node field, update offset.
The limit imposed by the kernel on the length of memfd_create first
argument is NAME_MAX - strlen("memfd:").
* memfd_create.c (SYS_FUNC(memfd_create)): Print the first argument
using printpathn.
* tests/memfd_create.c: Check it.
Although SHM_EXEC is available in <linux/shm.h> since kernel commit
v2.6.9-rc2~23^2~93^2~78, the glibc version of <sys/shm.h> did not
provide SHM_EXEC until commit glibc-2.10~238.
* xlat/shm_flags.in (SHM_EXEC): Add fallback definition.
* tests/shmxt.c (SHM_EXEC): Likewise.
NETLINK_LIST_MEMBERSHIPS, unlike all other SOL_NETLINK options, requests
not just a single integer but an array of integers. The kernel also
supports a zero optlen NETLINK_LIST_MEMBERSHIPS request.
* net.c (print_uint32): New function.
(print_getsockopt): Add ulen argument, rename len argument to rlen,
<SOL_NETLINK> Handle NETLINK_LIST_MEMBERSHIPS using print_array
and print_uint32.
(SYS_FUNC(getsockopt)): Pass ulen to print_getsockopt.
* tests/sockopt-sol_netlink.c (main): Check NETLINK_LIST_MEMBERSHIPS
decoding.
