of the strncat and strncpy function that may result in truncating
the copied string before the terminating NUL. To avoid false positive
warnings for correct code that intentionally creates sequences of
characters that aren't guaranteed to be NUL-terminated, arrays that
are intended to store such sequences should be decorated with a new
nonstring attribute. This change add this attribute to Glibc and
uses it to suppress such false positives.
ChangeLog:
* misc/sys/cdefs.h (__attribute_nonstring__): New macro.
* sysdeps/gnu/bits/utmp.h (struct utmp): Use it.
* sysdeps/unix/sysv/linux/s390/bits/utmp.h (struct utmp): Same.
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.
This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.
For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round. This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.
For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.
(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)
Tested for x86_64, and with build-many-glibcs.py.

- Guarded storage facility
Note: arch12 is NOT the official name of the new CPU.

ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags):
Add vxd, vxe, gs flag.
* sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXD, HWCAP_S390_VXE,
HWCAP_S390_GS capability.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h
(HWCAP_S390_VXD, HWCAP_S390_VXE, HWCAP_S390_GS): Define.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h. The others
get bits/types/ headers.
Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion. Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API). Relatedly, the public signal.h no longer
declares any of those functions. The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.
New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary. Ports to other operating systems
are strongly encouraged to generalize this scheme further.

This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

The HWCAP_S390_VX flag in hwcap field of auxiliary vector indicates
if the vector facility is available and the kernel is aware of it.
This can be tested with LD_SHOW_AUXV=1 <prog>.
Currently it does not show te, because it was not incremented
by commit "S/390: Add hwcap value for transactional execution.".
Thus _DL_HWCAP_COUNT is incremented by two.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_platforms): Add vector flag.
* sysdeps/s390/dl-procinfo.h: Add vector capability.

On s390 the following tests are failing due to unkown types time_t, pid_t:

FAIL: conform/XOPEN2K8/sys/sem.h/conform
FAIL: conform/XPG3/sys/sem.h/conform
FAIL: conform/XPG4/sys/sem.h/conform
This patch changes the s390 specific sem.h and includes sys/types.h instead
of bits/types.h. All other archs include sys/types.h, too.
Including bits/wordsize.h is obselete, because it is already inlcuded in
sys/types.h -> bits/types.h.
ChangeLog:
* sysdeps/unix/sysv/linux/s390/bits/sem.h:
Include sys/types.h instead of bits/types.h.
Remove inclusion of bits/wordsize.h.
Kay Sievers reported that coreutils' stat tool has a problem with
s390's statfs[64] definition:
> The definition of struct statfs::f_type needs a fix. s390 is the only
> architecture in the kernel that uses an int and expects magic
> constants lager than INT_MAX to fit into.
>
> A fix is needed to make Fedora boot on s390, it currently fails to do
> so. Userspace does not want to add code to paper-over this issue.
[...]
> Even coreutils cannot handle it:
> #define RAMFS_MAGIC 0x858458f6
> # stat -f -c%t /
> ffffffff858458f6
>
> #define BTRFS_SUPER_MAGIC 0x9123683E
> # stat -f -c%t /mnt
> ffffffff9123683e
The bug is caused by an implicit sign extension within the stat tool:
out_uint_x (pformat, prefix_len, statfsbuf->f_type);
where the format finally will be "%lx".
A similar problem can be found in the 'tail' tool.
s390 is the only architecture which has an int type f_type member in
struct statfs[64]. Other architectures have either unsigned ints or
long values, so that the problem doesn't occur there.
Therefore change the type of the f_type member to unsigned int, so
that we get zero extension instead sign extension when assignment to
a long value happens.
