inclusion of the appropriate xlat header in XLAT_MACROS_ONLY mode
does the right thing.

Remove, a fallback definition is already provided by included

Co-Authored-by: Dmitry V. Levin <ldv@altlinux.org>
* xlat/socketlayers.in: Add a comment that the xlat is sorted.
* net.c (print_sockopt_fd_level_name): Use printxval_search
instead of printxval for decoding socket layer name.
As we have all BTPROTO_* constant definitions now, there is no need
to rely on bluetooth.h header anymore.
* net.c (AF_BLUETOOTH): Provide a fallback definition.
[HAVE_BLUETOOTH_BLUETOOTH_H]: Do not include <bluetooth/bluetooth.h>.
[!HAVE_BLUETOOTH_BLUETOOTH_H]: Include "xlat/bt_protocols.h".

(decode_sockbuf) <case AF_BLUETOOTH>: Use printxval_index.
* xlat/bt_protocols.in: Add "#value_indexed" directive.
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.
Tweak the parser to follow the kernel behaviour.
* net.c (print_getsockopt, print_setsockopt) <SOL_NETLINK>: Fetch and
print returned value as integer iff the length is >= sizeof(int),
otherwise print the address.
* NEWS: Mention this.
* xlat/socknetlinkoptions.in: New file.
* net.c: Include "xlat/socknetlinkoptions.h".
(print_sockopt_fd_level_name) <SOL_NETLINK>: Print name using
socknetlinkoptions.
* NEWS: Metnion this.
The size of struct group_req depends on alignment of long and therefore
has to be mpersified.
* print_group_req.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* net.c (print_group_req): Move to print_group_req.c, wrap into
MPERS_PRINTER_DECL.
* net.c (print_group_req): Allow option length greater than
sizeof(struct group_req) to match the kernel behaviour.
When the option length is invalid, print the address.
* NEWS: Mention this.
As multicast socket options are shared between IPv4 and IPv6,
they should be decoded both for SOL_IP and SOL_IPV6.
* net.c (print_setsockopt) <SOL_IPV6> [MCAST_JOIN_GROUP]: Handle
MCAST_JOIN_GROUP and MCAST_LEAVE_GROUP.
* net.c (print_mreq, print_mreq6): Treat negative option length
as invalid to match the kernel behaviour. When the option length
is invalid, print the address.
* NEWS: Mention it.
* tests/ip_mreq.c (main): Check it. Update expected output.
* print_fields.h (PRINT_FIELD_SOCKADDR): New macro.
* msghdr.c (print_cmsg_ip_recverr): Use it instead of print_sockaddr.
* net.c (print_group_req): Likewise.
* sock.c (PRINT_IFREQ_ADDR): Remove.
(print_ifreq, print_ifconf_ifreq): Use PRINT_FIELD_SOCKADDR
instead of PRINT_IFREQ_ADDR.
print_sockaddr does not use its first argument, remove it.
* defs.h (print_sockaddr): Remove argument.
* sockaddr.c (print_sockaddr): Remove argument. All callers updated.
* sock.c (PRINT_IFREQ_ADDR): Likewise.
* net.c (print_tpacket_stats, print_tpacket_req): Use PRINT_FIELD_U.
(print_group_req): Use PRINT_FIELD_IFINDEX.
(print_packet_mreq): Use PRINT_FIELD_IFINDEX, PRINT_FIELD_U,
and PRINT_FIELD_XVAL.
* bpf_sock_filter.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* xlat/skf_ad.in: New file.
* defs.h (decode_sock_fprog, print_sock_fprog): New prototypes.
* fetch_bpf_fprog.c (get_bpf_fprog_size): New mpers printer.
* net.c (print_getsockopt): Use decode_sock_fprog to print
socket filter programs for SO_GET_FILTER socket option.
(print_setsockopt): Use decode_sock_fprog and get_bpf_fprog_size
to print socket filter programs for SO_ATTACH_FILTER
and SO_ATTACH_REUSEPORT_CBPF socket options.
* NEWS: Mention this.
* net.c (print_linger): Rename to print_set_linger.
(print_setsockopt): Replace print_linger with print_set_linger.
(print_get_linger): New function that accepts arbitrary option length
to match the kernel behaviour.
(print_getsockopt): Replace print_linger with print_get_linger.
* NEWS: Mention this.
As the last argument of getsockopt syscall has read-write semantics,
print both user and kernel values when they differ.
* net.c (SYS_FUNC(getsockopt)): On entering syscall, fetch and save
the length specified to the kernel. On error, print the length saved
on entering. When the saved length and the length returned by the
kernel differ, print both values.
* NEWS: Mention this.
* tests/net-icmp_filter.c (main): Update expected output.
The side effect of #include "xlat/netlink_protocols.h" is
NETLINK_* constants properly defined in that header file.
While net.c does not use these constants itself, netlink.c
is going to need them soon.
* net.c: Move inclusion of "xlat/netlink_protocols.h" ...
* netlink.c: ... here.
Remove temporary macros created for transition from long
to kernel_ulong_t.
Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'
* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove. All users updated.
Remove temporary types created for transition from long
to kernel_ulong_t.
Automatically replace kernel_scno_t and kernel_ureg_t with
kernel_ulong_t using
$ git grep -El 'kernel_(scno|ureg)_t' |
xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'
* kernel_types.h (kernel_scno_t, kernel_ureg_t): Remove.

unsigned long to kernel_ulong_t.
* defs.h (PRI_krd, PRI_kru, PRI_krx): New temporary macros.
All users updated.
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.
* defs.h (printstr): Rename to printstrn. All callers updated.
(printstr): New static inline function. All callers updated.
As new constants have been added gradually over kernel releases, define
all constant values to make newer constants decoded properly when strace
is built with older kernel headers.
* xlat/netlink_protocols.in: Add default values for constants.
* net.c [!NETLINK_SOCK_DIAG && NETLINK_INET_DIAG]: Remove.
* socketutils.c: Likewise.
As we've got a proper mechanism that parsers can use for storing private
data between entering and exiting stages, all cases of struct tcb.auxstr
abuse should go.
* btrfs.c (btrfs_ioctl): Use set_tcb_priv_ulong and get_tcb_priv_ulong
instead of abusing tcp->auxstr.
* file_handle.c (SYS_FUNC(name_to_handle_at)): Likewise.
