* tests/netlink_netfilter.c: Include <netinet/in.h>, <arpa/inet.h>
and <linux/netfilter/nf_tables.h>.
Replace "netlink.h" with "test_netlink.h".
(NFNL_SUBSYS_NFTABLES, NFT_MSG_NEWTABLE): New macros.
(test_nlmsg_done, test_nfgenmsg): New functions.
(main): Use them.
* bpf.c (DEF_BPF_CMD_DECODER(BPF_PROG_LOAD)): Print
union bpf_attr.kern_version in the form of KERNEL_VERSION macro call.
* tests/bpf.c: Update expected output.
Apparently, hppa is the only architecture that has MAP_TYPE
defined to 0x3 instead of 0xf, and the tests hit that corner case.
* tests/remap_file_pages.c (main) [MAP_HUGETLB]: Print the value
of mapping type depending on the architecture (MAP_SHARED_VALIDATE
for hppa and unknown value for other architectures).
Fixes: v4.21~59 ("xlat: update MAP_* constants")
When built with --enable-gcc-Werror, s390_sthyi test build fails
with the following error:
s390_sthyi.c:63:1: error: ‘print_u8’ defined but not used [-Werror=unused-function]
print_u8(const char *prefix, unsigned char *buf, unsigned int offs, bool zero)
^~~~~~~~
Apparently, after some back and forth, all occurrences of printing u8
values landed under verbose printing, so this function is no longer
used in non-verbose mode. Let's avoid this in the future by inlining
all the utility functions in this test.
* tests/s390_sthyi.c (print_0x8, print_u8, print_u16, print_x32,
print_weight, ebcdic2ascii, is_empty, print_ebcdic): Add inline
qualifier.
[!VERBOSE] (is_empty): Remove "# if VERBOSE" guard.
The field has been introduced in Linux commit v4.15-rc1~135^2~17.
* btrfs.c: Implement decoding of
struct btrfs_ioctl_logical_ino_args.flags field.
* configure.ac: Check for struct btrfs_ioctl_logical_ino_args.flags
presence in linux/btrfs.h.
* tests/btrfs.c: Update expected output, add additional checks.
* xlat/btrfs_logical_ino_args_flags.in: New file.
* btrfs.c (btrfs_ioctl) <case BTRFS_IOC_INO_PATHS>: Print fspath field
with printaddr64.
(btrfs_ioctl) <case BTRFS_IOC_LOGICAL_INO>: Print inodes field with
printaddr64.
* tests/btrfs.c: Add checks for NULL in fspath and inodes fields.
* NEWS: Mention it.
* xlat/v4l2_pix_fmts.in: New file.
* xlat/v4l2_sdr_fmts.in: Likewise.
* v4l2.c [!v4l2_fourcc_be] (v4l2_fourcc_be): New macro.
(print_pixelformat): Add xlat parameter, print constant name
as a comment if it has been found in xlat.
(print_v4l2_fmtdesc, print_v4l2_frmivalenum): Pass v4l2_pix_fmts
to print_pixelformat.
(print_v4l2_format_fmt) <case V4L2_BUF_TYPE_VIDEO_CAPTURE, case
V4L2_BUF_TYPE_VIDEO_OUTPUT, case V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE,
case V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE, case V4L2_BUF_TYPE_VBI_CAPTURE,
case V4L2_BUF_TYPE_VBI_OUTPUT>: Pass v4l2_pix_fmts to print_pixelformat.
(print_v4l2_format_fmt) <case V4L2_BUF_TYPE_SDR_OUTPUT, case
V4L2_BUF_TYPE_SDR_CAPTURE>: Pass v4l2_sdr_fmts to print_pixelformat.
* tests/v4l2.c: Test it, update expected output.
* NEWS: Mention it.
v4l2_fourcc(a, b, c, d) is defined as (a | (b << 8) | (c << 16) | (d << 24)
regardless of endianness (no mnemonic on big-endian architectures),
so we don't need special handling for WORDS_BIGENDIAN both in decoder
and in the test.
* v4l2.c (print_pixelformat): Change initialisation to a simple
assignment of character array.
* tests/ioctl_v4l2.c [WORDS_BIGENDIAN]: Remove.
* NEWS: Mention this fix.

Starting with commit v4.21-37-g4f63bc70ca95012d72e288fc3c1eeb3ba26068a4,

Quotes are not always used to denote string limits; printfd uses angle
brackets for that, for example. As result, mechanism for supplying
set of additional characters in order to avoid ambiguities regarding
the end of the quoted string is needed.

When built with -O0, gcc (rightfully) generates function prologue, which
results in writing %rbp to the stack, causing premature KVM_EXIT_MMIO.
It could be possible to avoid such problems by "naked" attribute but,
unfortunately, the latter is not available on x86 with older GCC.
A trick suggested in [1] is used instead: assembly is moved
to the global scope.

* tests/ioctl_kvm_run.c (code): Remove function.
Add globally scoped __asm__ with the function code and its size.
(code, code_size): New extern symbols declarations.
(run_kvm): Remove code_size definition and initialization.

As it has proven itself useful.
* tests/ioctl_kvm_run.c (run_kvm) <case KVM_EXIT_MMIO:>: Fail
on unexpected KVM_EXIT_MMIO, providing relevant diagnostics.
Recent glibc (since version 2.26) uses accept4 syscall for implementing
accept call on sparc. Unfortunately, it's impossible to simply fall
back on raw syscall as it had not been wired up until linux commit
v4.4-rc8~4^2~1.
* tests/accept_compat.h: New file.
* tests/Makefile.am (EXTRA_DIST): Add it.
* tests/net-y-unix.c: Include accept_compat.h, use do_accept()
instead of accept() calls.
* tests/net-yy-inet.c: Likewise.
* tests/net-yy-unix.c: Likewise.
* tests/net.expected: Allow accept4.
* xlat/pkey_access.in (PKEY_DISABLE_EXECUTE): New constant introduced
by linux kernel commit v4.16-rc1~93^2~85.
* tests/pkey_alloc.c: Update expected output.
* NEWS: Mention it.
Include "ptrace.h" before any header that can include <signal.h>
because on some architectures the latter may include <asm/sigcontext.h>
which in turn may include <asm/ptrace.h> with potentially devastating
effect on <sys/ptrace.h>.
* process.c: Include "ptrace.h" before "regs.h".
* rt_sigframe.c: Likewise.
* sigreturn.c: Include "ptrace.h" before "nsig.h".
* syscall.c: Likewise.
* wait.c: Include "ptrace.h" before <sys/wait.h>.
* strace.c: Include "ptrace.h" before <signal.h>.
* tests/ptrace.c: Likewise.
* tests/test_ucopy.c: Include <sys/ptrace.h> before <signal.h>.
* tests/accept.c [__NR_accept && !TEST_SYSCALL_NAME]: Define a wrapper that
calls accept directly.
* tests/sockname.c [TEST_SYSCALL_STR]: Do not define TEST_SYSCALL_STR.
gcc8 -Wall -Werror rejects our method of struct sockaddr_un.sun_path
initialization because the field lacks __nonstring__ attribute.
As we calculate the length of the string being copied anyway,
workaround this gcc+glibc bug by changing the code to use this
pre-calculated length and get rid of strncpy completely.
* tests/net-accept-connect.c (main): Use memcpy to initialize sun_path.
As definitions of O_* macros provided by various libc implementations
are usually less reliable than those provided by kernel headers, switch
to use kernel's fcntl.h header.
* open.c: Include <asm/fcntl.h> instead of <fcntl.h>. Remove
O_LARGEFILE fallback definitions assuming that the kernel headers
provide them.
* xlat/open_mode_flags.in: Add __O_SYNC after O_SYNC. Add O_TMPFILE
and __O_TMPFILE before O_DIRECTORY. Remove "O_TMPFILE & ~O_DIRECTORY".
* tests/open.c: Include <asm/fcntl.h> instead of <fcntl.h>. Remove
workarounds for libc O_TMPFILE implementations.
* tests/openat.c: Include <asm/fcntl.h> instead of <fcntl.h>.
(test_mode_flag): New function.
(main): Use it to check decoding of all access modes and file flags.
* tests/gen_tests.in (openat): Add -a option.

As the remaining non-generated ioctl tests differ from ioctl.test only
in strace options, and since gen_tests.sh can pass arguments to sourced
tests, replace the remaining non-generated ioctl tests with invocations
of ioctl.test with appropriate parameters.
* tests/ioctl.test: Pass script arguments to the strace invocation.
* tests/gen_tests.in (ioctl_dm): New entry, invoke ioctl.test with -s9.
(ioctl_dm-v): New entry, invoke ioctl.test with -v -s9.
(ioctl_kvm_run): New entry, invoke ioctl.test with -a36 -y.
(ioctl_loop-nv): New entry, invoke ioctl.test with -a22 -e verbose=none.
(ioctl_nsfs): New entry, invoke ioctl.test with -esignal=none.
(ioctl_sock_gifconf): New entry, invoke ioctl.test with -a28 -s1.
(ioctl_evdev-v, ioctl_loop-v, ioctl_rtc-v): Invoke ioctl.test
with -v option instead of ioctl-v.sh.
* tests/ioctl_dm-v.test: Remove.
