2fd4bbaa14 linux/aarch64: sync sys/ptrace.h with Linux 4.15 [BZ #22433] 
Remove compat-specific constants that were never exported by kernel
headers under these names.  Before linux commit v3.7-rc1~16^2~1 they
were exported with COMPAT_ prefix, and since that commit they are not
exported at all.

* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (__ptrace_request):
Remove arm-specific PTRACE_GET_THREAD_AREA, PTRACE_GETHBPREGS,
and PTRACE_SETHBPREGS.

c739e191d0 aarch64: Revert the change of the __reserved member of mcontext_t 
The uc_mcontext.__reserved member of ucontext_t is a user visible API,
that should not be changed, because this is the only way to access cpu
states of various extensions of linux asm/sigcontext.h, it does not
violate namespace rules either, so revert this part of the commit

commit 4fa9b3bfe6
Commit:     Joseph Myers <joseph@codesourcery.com>

    Fix mcontext_t sigcontext namespace (bug 21457).

(In principle the user can type cast &uc_mcontext to struct sigcontext*
to use the linux sigcontext fields, but that's not the existing practice
since mcontext_t used to be a typedef of struct sigcontext.)

	Rename to __reserved and add comment.
	* sysdeps/unix/sysv/linux/aarch64/ucontext_i.sym (__glibc_reserved1):

4fa9b3bfe6 Fix mcontext_t sigcontext namespace (bug 21457). 
This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.

Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel.  This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).

Tested for x86_64, and with build-many-glibcs.py.

60e2846e26 sys/ptrace.h: remove obsolete Linux PTRACE_SEIZE_DEVEL constant [BZ #21928] 
Remove enum __ptrace_flags along with the only constant it contains,
PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files.

This temporary development constant shouldn't have been added to
sys/ptrace.h in the first place.  It was introduced in Linux by commit
v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE
interface.  Later, as PTRACE_SEIZE stabilized and lost its experimental
status, this flag was removed from Linux by commit v3.4-rc1~109^2~20.

3d452dabd1 Fix uc_* namespace (bug 21457). 
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.

The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>).  Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.

This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined.  Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.

This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).

Tested for x86_64, and with build-many-glibcs.py.

251287734e Rename struct ucontext tag (bug 21457). 
The ucontext_t type has a tag struct ucontext.  As with previous such
issues for siginfo_t and stack_t, this tag is not permitted by POSIX
(is not in a reserved namespace), and so namespace conformance means
breaking C++ name mangling for this type.

In this case, the type does need to have some tag rather than just a
typedef name, because it includes a pointer to itself.  This patch
uses struct ucontext_t as the new tag, so the type is mangled as
ucontext_t (the POSIX *_t reservation applies in all namespaces, not
just the namespace of ordinary identifiers).  Another reserved name
such as struct __ucontext could of course be used.

Because of other namespace issues, this patch does not by itself fix
bug 21457 or allow any XFAILs to be removed.

Tested for x86_64, and with build-many-glibcs.py.

cfed8ece79 Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457). 
The various sys/ucontext.h headers include <signal.h> and all the
headers split out of <bits/sigstack.h>.  (Except that the powerpc
version does not include <signal.h>.)

None of the standard versions defining ucontext.h require or permit
such inclusions; rather, they all say that the stack_t and sigset_t
types from signal.h are defined.  This patch fixes the headers to
include just the bits/ headers for those types (and the existing
includes of bits/sigcontext.h).  Since bits/types/sigset_t.h is now
being included instead of bits/types/__sigset_t.h, __sigset_t uses in
the headers are replaced by direct use of the public sigset_t type.
sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior
inclusion of <signal.h> to define types such as __uint32_t, so gets a
bits/types.h include added to provide those types.

Although one could keep some or all of the includes under a __USE_MISC
conditional, that seems unnecessary to me, especially given the lack
of a <signal.h> include in the powerpc version meaning that portable
programs already cannot rely on such an include.

Tested for x86_64 and x86, and with build-many-glibcs.py.  As with
other such fixes, more namespace issues remain so this does not permit
any XFAILs to be removed or bugs to be closed.

a992f506ff Remove __need macros from signal.h. 
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.

0bcec5321f Split up bits/sigstack.h. 
bits/sigstack.h contains four things: the legacy struct sigstack type,
the preferred stack_t type, the SS_* enum values and macros for signal
stack sizes.

These vary in different ways between glibc configurations; in
particular, the stack sizes vary much more than any of the other
pieces.  Furthermore, these pieces have different standard namespace
rules for when they should be visible (not currently visible in
conform/ results both because the relevant tests are XFAILed for
sys/ucontext.h namespace issues, and because some of the expectations
are incorrect in the same way as the headers, e.g. neither
expectations nor headers reflect that current POSIX no longer has
either the sigstack function or the sigstack structure).

To reduce duplication of identical definitions, and facilitate
namespace fixes without requiring the same feature test macro
conditions to be repeated in many versions of the same header, this
patch splits bits/sigstack.h up into four headers.  It keeps the stack
size macros, while new bits/types/struct_sigstack.h,
bits/types/stack_t.h and bits/ss_flags.h are added for the other
pieces.  bits/types/struct_sigstack.h is the same everywhere,
bits/types/stack_t.h has three variants different in the order of the
structure elements (generic = MIPS Linux, and other Linux), and
bits/ss_flags.h has generic and Linux variants.

This patch includes the new headers everywhere that included
<bits/sigstack.h>, so should cause no difference to what any public
header defines.  Subsequent namespace fixes would then remove or
condition some of those includes.

There should be no conflicts with Zack's changes to signal.h types,
beyond the trivial conflict of both making additions to
signal/Makefile's headers list; the two patches affect disjoint sets
of types and other definitions.

Tested for x86_64 and x86, and with build-many-glibcs.py.

5df4854ed2 Condition some sys/ucontext.h contents on __USE_MISC (bug 21457). 
Continuing the fixes for namespace issues arising from sys/ucontext.h,
this patch conditions various definitions, that are not needed for
defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear
in strict POSIX modes.

This patch is non-exhaustive; that is, it only conditions
straightforward cases and there may be more such definitions that can
be conditioned for these and other architectures, to be dealt with
later in separate patches.  Also, using __USE_MISC is the minimum
change for these definitions where they conflict with POSIX; some
headers already have __USE_GNU conditionals on similar definitions of
names for registers.  The patch specifically does not do anything with
definitions in bits/sigcontext.h, and nor does it condition any
inclusions of bits/sigcontext.h even where in fact that is not needed
on some architectures for the definitions of mcontext_t / ucontext_t.

As other namespace issues in these headers remain, this patch does not
fix bug 21457, nor allow any XFAILs to be removed.

Tested with build-many-glibcs.py.

3f67d1a702 Add Linux PTRACE_EVENT_STOP 
Add PTRACE_EVENT_STOP value to Linux's sys/ptrace.h, modify related
comments accordingly.

This constant initially appeared in Linux 3.1 (kernel commit 3544d72a,
"ptrace: implement PTRACE_SEIZE") but its value has changed later
in Linux 3.4 (kernel commit 5cdf389a, "ptrace: renumber
PTRACE_EVENT_STOP so that future new options and events can match").

The comment is also taken from the above commit.

This constant is used by e.g. strace, CRIU, Mozilla RR.

c66b29f9cc Installed-header hygiene (BZ#20366): stack_t. 
sys/ucontext.h unconditionally uses stack_t, and it does not make
sense to change that.  But signal.h only declares stack_t under
__USE_XOPEN_EXTENDED || __USE_XOPEN2K8.  The actual definition is
already in a bits header, bits/sigstack.h, but that header insists on
only being included by signal.h, so we have to change that as well as
all of the sys/ucontext.h variants.  (Some but not all variants of
bits/sigcontext.h, which sys/ucontext.h may also need, had already
received this adjustment; for consistency, I made them all the same,
even if that's not strictly necessary in some configurations.)
bits/sigcontext.h and bits/sigstack.h also all need to receive
multiple inclusion guards.

fb53a27c57 Add new header definitions from Linux 4.4 (plus older ptrace definitions). 
This patch adds some new header definitions from Linux 4.4:

* MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was
  already done for hppa).

* PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h.  Along with it,
  the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux
  3.11 but missed at the time, are also added.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

b8528e771c [AArch64][BZ 18648] change greg_t definition in ucontext.h 
This is an ABI breaking change, but

	typedef int greg_t;

is not a useful definition on aarch64.

greg_t is usually used for defining gregset_t which is used
in mcontext_t.  The general registers in mcontext_t can only
be accessed by target specific code and on aarch64 greg_t
is not needed for that so this change is not supposed to break
existing code, just fix the definition.

	[BZ #18648]
	* sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (greg_t): Change the
	definition to elf_greg_t.

(Added another BZ entry that was missed in the previous commit).

14d623bcd1 [AArch64][BZ 18400] fix elf_prpsinfo in procfs.h 
Kernel uses int pr_uid, pr_gid, but glibc used unsigned short.

This is an ABI breaking change, but the size and alignment of
the struct and the layout of other members is not changed and
there is no known usage of pr_uid and pr_gid so it is expected
to be safe.

	[BZ #18400]
	* sysdeps/unix/sysv/linux/aarch64/sys/procfs.h (struct elf_prpsinfo):
	Fix pr_uid and pr_gid members.

7d05a8168b AArch64: Remove asm/ptrace.h inclusion in sys/user.h and sys/procfs.h 
This patch fixes an issue observed by the Xen project, where including
signal.h exposes various PSR_MODE #defines.  This is due to the usage
in sys/user.h and sys/procfs.h of the struct user_pt_regs and
user_fpsimd_state included via asm/ptrace.h.  The namespace pollution
this inclusion introduce is already partially fixed with some #undef
of the PTRACE_* symbols, but other symbols like the PSR_MODE ones are
still present, and undefining them is not safe since a user can
include ptrace.h before user.h.

My proposition is to define the 2 structures we need in user.h and get
rid of the asm/ptrace.h inclusion.

Build and make check are clean on AArch64.

75eff3fe90 Relocate AArch64 from ports to libc. 
This patch moves the AArch64 port to the main sysdeps hierarchy.  The
move is essentially:

  git mv ports/sysdeps/aarch64 sysdeps/aarch64
  git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64

The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move.  The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
