tests/*.c

* tests/tests.h: New file.
* tests/error_msg.c: Likewise.
* tests/tail_alloc.c: Likewise.
* tests/get_page_size.c: Likewise.
* tests/Makefile.am (libtests_a_SOURCES, libtests_a_CPPFLAGS,
check_LIBRARIES, LDADD): New variables.
(clock_xettime_LDADD, filter_unavailable_LDADD, mq_LDADD,
pc_LDADD, times_LDADD): Add $(LDADD).
* tests/.gitignore: Add libtests.a.

tests: enable strace-k.test only for --with-libunwind configurations

Also, since -k option does not support multiple personalities,
add strace-k.test to XFAIL_TESTS when running mpers tests.

* tests/Makefile.am (MPERS_NAME, LIBUNWIND_TESTS, XFAIL_TESTS_,
XFAIL_TESTS_m32, XFAIL_TESTS_mx32, XFAIL_TESTS): New variables.
[USE_LIBUNWIND] (LIBUNWIND_TESTS): Add strace-k.test.
(TESTS): Replace strace-k.test with $(LIBUNWIND_TESTS).
* bootstrap: Substitute MPERS_NAME variable in tests-*/Makefile.am.
* tests/strace-k.test: Do not check for -k option availability.

Move gcc compat macros to gcc_compat.h

* defs.h: Include "gcc_compat.h".
(GNUC_PREREQ, ATTRIBUTE_NORETURN, ATTRIBUTE_FORMAT,
ATTRIBUTE_ALIGNED, ATTRIBUTE_PACKED, ATTRIBUTE_MALLOC,
ATTRIBUTE_NOINLINE, ATTRIBUTE_ALLOC_SIZE): Move ...

* test/Makefile (PROGS): Remove fork and vfork.
* test/.gitignore: Remove fork and vfork.

Check how strace -f follows fork and vfork syscalls.

Set SYSCALL_NEVER_FAILS flag for getpid, getppid and gettid syscall

* linux/*/syscallent*.h (getpid, getppid, gettid): Set NF flag.

Set SYSCALL_NEVER_FAILS flag for umask syscall

Linux kernel always ANDs umask argument with 0700 and therefore
this syscall never fails.

* linux/*/syscallent*.h (umask): Set NF flag.

alpha, ia64, mips, nios2, powerpc, sparc: always check for syscall error

On architectures that use dedicated registers to report syscall errors,
check for syscall error condition regardless of SYSCALL_NEVER_FAILS flag
in the syscall entry.  On architectures that use negated errno
semantics, there is no way to distinguish a syscall error from a valid
return code that looks like a syscall error, and the check for
SYSCALL_NEVER_FAILS flag remains the only way to tell one case
from another.

* linux/alpha/get_error.c (get_error): Ignore check_errno.
* linux/ia64/get_error.c: Likewise.
* linux/mips/get_error.c: Likewise.

* linux/powerpc/get_error.c: Likewise.
* linux/sparc/get_error.c: Likewise.
* linux/sparc64/get_error.c: Likewise.

Handle unlikely errors from personality syscall

Despite being marked as SYSCALL_NEVER_FAILS, personality syscall still
might report a failure on some architectures due to obscure kernel
bugs.  Check for this unlikely case and let users know that their
kernel has gone bananas.

* personality.c (SYS_FUNC(personality)): Do not parse syscall return
value in case of syserror.

Do not truncate return value of get{,e}[ug]id and setfs[ug]id syscalls

This should not be a user visible change unless the kernel does
something completely unexpected.  In the latter case, let user see
what is going on.

* uid.c (SYS_FUNC(getuid), SYS_FUNC(setfsuid)): Do not truncate
tcp->u_rval to uid_t on exiting syscall, return RVAL_DECODED.

Enhance personality syscall decoding

* xlat/personality_options.in: Split into ...
* xlat/personality_types.in: ... personality types and ...
* xlat/personality_flags.in: ... personality flags.
* personality.c: Include "xlat/personality_types.h"
and "xlat/personality_flags.h" instead of "xlat/personality_options.h".
(SYS_FUNC(personality)): Print PER_MASK part of personality as
a symbolic value, and the rest of personality as a set of flags.
* tests/personality.c (main): Add more test cases.
* tests/personality.test: Update.

sh, sh64: fix syscall flags in several syscall entries

* linux/sh/syscallent.h (geteuid32, getegid32, setfsuid32, setfsgid32):
Set SYSCALL_NEVER_FAILS flag.
(fchown32): Set TRACE_DESC flag.
* linux/sh64/syscallent.h: Likewise.

Print personality value 0xffffffff properly

Value 0xffffffff of personality syscall first argument has a special
meaning, it is not a set of personality flags.

* personality.c (SYS_FUNC(personality)): If personality equals
to 0xffffffff, print it verbatim.
* tests/personality.c (main): Test it.

tests: add personality.test

* tests/personality.c: New file.
* tests/personality.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add personality.
(TESTS): Add personality.test.
* tests/.gitignore: Add personality.

Enhance personality syscall decoding

* personality.c (SYS_FUNC(personality)): On entering syscall,
print first argument not as a hex value but as a set of flags.
On exiting syscall, print return code as a set of flags.
* NEWS: Mention this enhancement.

Set SYSCALL_NEVER_FAILS flag for personality syscall

Starting with commit
v2.6.29-6609-g11d06b2a1e5658f448a308aa3beb97bacd64a940, personality
syscall never fails to set the personality, but before commit
v2.6.35-rc1-372-g485d527 it still could return an error.
Starting with that commit, personality syscall never returns an error.

* linux/*/syscallent.h: Set SYSCALL_NEVER_FAILS flag in personality
syscall entries.

Add personality emulation flags

* xlat/personality_options.in: Add UNAME26, ADDR_NO_RANDOMIZE,
FDPIC_FUNCPTRS, MMAP_PAGE_ZERO, ADDR_COMPAT_LAYOUT, READ_IMPLIES_EXEC,
ADDR_LIMIT_32BIT, SHORT_INODE, WHOLE_SECONDS, STICKY_TIMEOUTS,
and ADDR_LIMIT_3GB.

* NEWS: Mention this build fix.

packages: remove acl development library from build dependencies

Starting with commit v4.9-46-g681452b that removed all references
to acl.h, we no longer use acl development library.

* .travis.yml (addons.apt.packages): Remove libacl1-dev.
* strace.spec (BuildRequires): Remove libacl-devel.

packages/x86_64: enable experimental -k option

* debian/control (Build-Depends) [amd64]: Add libunwind-dev.

ia64: wire up mlock2 syscall

* linux/ia64/syscallent.h [1346]: Add mlock2 entry.

Add copyright headers to some files which lack them

Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't.  This
change fixes the inconsistency by adding missing copyright headers.

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.

tests/aio.c: include <time.h>

* tests/aio.c: Include <time.h> for struct timespec.
