Since aarch64/syscallent1.h and tile/syscallent.h share a lot of
identical syscall entries described in <asm-generic/unistd.h>, move
these entries to a new file 64/syscallent.h using the following
automated conversion with subsequent correction of whitespace
indentation:
sed -e 's|^[[:space:]]*\({[^}]\+},\)[[:space:]]*/\*[[:space:]]\([[:space:]]*[0-9]\+\)[[:space:]]*\*/|[\2] = \1|' -e '/^\[[[:space:]]*2\(4[4-9]\|5[0-9]\)\]/d' linux/tile/syscallent.h
* linux/64/syscallent.h: New file.
* Makefile.am (EXTRA_DIST): Add it.
* linux/aarch64/syscallent1.h: Include "64/syscallent.h",
remove generic 64-bit syscall entries, use designated initializers.
* linux/tile/syscallent.h: Likewise.
Reserve the same space for new syscalls on EABI as it is already
reserved on OABI.
* linux/arm/syscallent.h [__ARM_EABI__] (ARM_FIRST_SHUFFLED_SYSCALL):
Raise to 400.
indirect_ipccall used to guess whether currently decoded ipc syscall is
an indirect subcall or not based on generic knowledge, while there is a
robust method to identify indirect ipc subcalls.
* defs.h (TRACE_INDIRECT_SUBCALL): New flag.
* ipc.c (indirect_ipccall): Check it.
* linux/subcall.h: Set it.
Syscall entries for socket and ipc subcalls are the same on all
architectures, or at least they should be the same, so move them
to the single file.
* linux/subcall.h: Add syscall entries for socket and ipc subcalls.
* linux/arm/syscallent.h: Remove entries for socket and ipc subcalls.
* linux/i386/syscallent.h: Likewise.
* linux/m68k/syscallent.h: Likewise.
* linux/powerpc/syscallent.h: Likewise.
* linux/s390/syscallent.h: Likewise.
* linux/s390x/syscallent.h: Likewise.
* linux/sh/syscallent.h: Likewise.
* linux/sh64/syscallent.h: Likewise.
* linux/sparc/syscallent.h: Likewise.
Before this change, ioctlent.sh could not recognize unusual constants
defined by linux/aufs_type.h, resulting to ioctls.h with references to
these constants without appropriate definitions in ioctldefs.h.
* linux/ioctlent.sh: Update the regexp that is used to lookup constants
referenced by generated ioctls.h.
This change extends -yy option to handle unix domain sockets:
their peer addresses will be printed, similar to inet sockets.
For a listening socket, its socket inode and socket path are printed.
For an accepted socket, its socket inode, the peer inode, and the
socket path are printed.
For a client socket, its socket inode and the peer inode are printed.
An example of a server side communication using netcat:
$ ./strace -yy -e network nc -l -U /tmp/example.sock
socket(PF_LOCAL, SOCK_STREAM, 0) = 3
setsockopt(3<UNIX:[14728348]>, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(3<UNIX:[14728348]>, {sa_family=AF_LOCAL, sun_path="/tmp/example.sock"}, 19) = 0
listen(3<UNIX:[14728348,"/tmp/example.sock"]>, 10) = 0
accept(3<UNIX:[14728348,"/tmp/example.sock"]>, {sa_family=AF_LOCAL, NULL}, [2]) = 4<UNIX:[14727246->14727245,"/tmp/example.sock"]>
recvfrom(4<UNIX:[14727246->14727245,"/tmp/example.sock"]>, "INPUT\n", 8192, 0, NULL, NULL) = 6
INPUT
An example of a client side communication using netcat:
$ ./strace -yy -e network nc -U /tmp/example.sock
socket(PF_LOCAL, SOCK_STREAM, 0) = 3
connect(3<UNIX:[14727245]>, {sa_family=AF_LOCAL, sun_path="/tmp/example.sock"}, 19) = 0
getsockopt(3<UNIX:[14727245]>, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
INPUT
...
sendto(3<UNIX:[14727245->14727246]>, "INPUT\n", 6, 0, NULL, 0) = 6
* linux/unix_diag.h: New file.
* socketutils.c (send_query): Rename to inet_send_query.
(parse_response): Rename to inet_parse_response.
(unix_print, unix_send_query, unix_parse_response): New functions.
(receive_responses): Add a new argument named parser: a function for
handling protocol specific data parts of diag messages.
(print_sockaddr_by_inode): Call unix_print.
Replace NETLINK_INET_DIAG with NETLINK_SOCK_DIAG, they are equal
but NETLINK_SOCK_DIAG looks more generic.

Convert parsers of these syscalls to the same scheme as were applied to
parsers of other uid/gid related syscalls.
That is, define two sets of parsers on architectures that support
(either directly or via multiarch) 16-bit and 32-bit gid getgroups
and setgroups syscalls simultaneously, and reuse essentially the same
code by parametrizing uid_t and names of parser functions.
* groups.c: Remove.
(sys_getgroups, sys_setgroups): Move ...
* uid.c: ... here and parametrize their names.
* Makefile.am (strace_SOURCES): Remove groups.c.
* linux/syscall.h (sys_getgroups32, sys_setgroups32): Remove.
[NEED_UID16_PARSERS] (sys_getgroups16, sys_setgroups16): New prototypes.

* tests/uid.test: Trace getgroups/getgroups32 syscalls.
Define two sets of parsers on architectures that support (either
directly or via multiarch) 16-bit and 32-bit uid/gid syscalls
simultaneously. Since the code in these two sets is essentially
the same and the key difference between them is the size of uid_t,
implement it by parametrizing uid_t and names of parser functions.
* defs.h (NEED_UID16_PARSERS): New macro.
* linux/syscall.h [NEED_UID16_PARSERS] (sys_chown16, sys_fchown16,
sys_getresuid16, sys_getuid16, sys_setfsuid16, sys_setresuid16,
sys_setreuid16, sys_setuid16): New prototypes.
* linux/dummy.h (sys_geteuid16): Alias to sys_getuid16.
(sys_getegid16, sys_getgid16, sys_getresgid16, sys_setfsgid16,
sys_setgid16, sys_setregid16, sys_setresgid16): Alias to corresponding
sys_*uid16 functions.

sys_geteuid16, sys_getgid16, sys_getresgid16, sys_getresuid16,
sys_getuid16, sys_setfsgid16, sys_setfsuid16, sys_setgid16,
sys_setregid16, sys_setresgid16, sys_setresuid16, sys_setreuid16,
and sys_setuid16 parsers for *chown and [gs]et*[gu]id syscall entries.

parsers in *chown32 and [gs]et*[gu]id32 syscall entries.
* linux/sh64/syscallent.h: Likewise.
* linux/sparc/syscallent.h: Add "32" suffix to names
of [gs]etres[gu]id32 syscalls #108..112.
Fix entry for syscall #112 from setresgid32 to setregid32.
Since parsers for setdomainname and sethostname syscalls are identical,
replace sys_setdomainname with an alias to sys_sethostname.
* linux/dummy.h (sys_setdomainname): Alias to sys_sethostname.
* linux/syscall.h (sys_setdomainname): Remove.
* process.c (sys_setdomainname): Remove.
Since parsers for getpeername and getsockname syscalls are identical,
replace sys_getpeername with an alias to sys_getsockname.
* linux/dummy.h (sys_getpeername): Alias to sys_getsockname.
* linux/syscall.h (sys_getpeername): Remove.

* linux/dummy.h (sys_stime): Alias to sys_time.

There are two important changes in here:
1. EWOULDBLOCK has been up to kernel 3.14 errorcode #246. Since hppa
folks had problems with EWOULDBLOCK != EAGAIN, this was changed in
kernel 3.14.
2. Starting with kernel 3.18, hppa folks changed some signal numbers in
such a way that we end up with SIGRTMIN == 32, which brings hppa in sync
with other linux ports.
Both were incompatible changes which basically broke hppa ABI, but since
they have been merged into the kernel, we have to follow.
For two ioctl entries with the same code, if one's name is a prefix
to another's name, keep the entry with a shorter name. Filter out
redundant ioctl entries at ioctlsort stage so that distributed
ioctlent.h.in files will be already filtered.
* linux/ioctlsort.c (is_not_prefix): New function.
(main): Use it.
* linux/ioctlent-filter.awk: Remove.
* Makefile.am (EXTRA_DIST): Remove linux/ioctlent-filter.awk.
($(ioctlent_h)): Don't use linux/ioctlent-filter.awk.
When two ore more -y options are given, print local and remote ip:port
pairs associated with socket descriptors. This implementation uses
NETLINK_INET_DIAG for sockaddr lookup; it's based on the patch
prepared by Zubin Mithra as a part of his GSoC 2014 strace project.
* Makefile.am (strace_SOURCES): Add socketutils.c
(EXTRA_DIST): Add linux/inet_diag.h and linux/sock_diag.h.
* defs.h (print_sockaddr_by_inode): New prototype.
* linux/inet_diag.h: New file.
* linux/sock_diag.h: Likewise.
* socketutils.c: Likewise.
* strace.1: Document -yy option.
* strace.c (usage): Likewise.
* util.c (printfd): Use print_sockaddr_by_inode.
When the preadv/pwritev syscalls were added, the ones before it in the
ia64 list were missed, so all the syscalls there and later were not in
the right location (causing things to be decoded incorrectly).
Add the missing syscalls before preadv which also re-aligns all the
syscalls after that point. This fixes the uio.test.
* linux/ia64/syscallent.h: Add syscalls 1310 through 1318.
Both these arches have a rt_sigaction syscall that takes 5 args, not 4.
* linux/alpha/syscallent.h (rt_sigaction): Change nargs to 5.
* linux/sparc/syscallent.h (rt_sigaction): Change nargs to 5.
Starting in 3.16, these two syscalls have gotten their own entry
point for x32. See linux 7fd44dacdd803c0bbf38bf478d51d280902bb0f1.
* linux/x32/syscallent.h: Change existing io_{setup,submit} to 64bit,
and add new entry points for x32 specifically.
