Corinna Vinschen 9409c5335b Don't test pthread objects for being already initialized at init time
For all pthread init functions, POSIX says

  Results are undefined if pthread_FOO_init() is called specifying an
  already initialized pthread_FOO object.

So far our pthread init functions tested the incoming object if it's
already an initialized object and, if so, returned EBUSY.  That's ok
*iff* the object was already initialized.  However, as the example in
https://cygwin.com/ml/cygwin/2016-04/msg00473.html shows, an uninitialized
pthread object could also accidentally look like an initialized object
and then returning EBUSY is not ok.

Consequentially, all those tests are dangerous.  Per POSIX, an application
has to know what its doing when calling any of the pthread init functions
anyway, and re-initializing the object is just as well as undefined
behaviour as is returning EBUSY on already initialized objects.

	* thread.cc (pthread_attr_init): Drop check for already initialized
	object.
	(pthread_condattr_init): Ditto.
	(pthread_rwlockattr_init): Ditto.

Corinna Vinschen 7a5b452443 Disallow S_ISGID on directories without default ACL entries
We can't handle the S_ISGID bit if the child didn't inherit a NULL SID
ACE with the S_ISGID bit set.  On directories without default ACL
entries we would have to add an inheritable NULL SID ACE and nothing else.
This in turn results in permission problems when calling set_file_sd
from set_created_file_access.  That's fixable, but it would only work
for files created from Cygwin while files created from native Windows
tools end up with really ugly permissions.

This patch only makes sure that the S_ISGID bit is reset for a directory
if it has no inheritable ACEs.  Still having the 's' bit shown in ls or
getfacl output would be misleading.  So, calling `setfacl -k' on a dir
also removes the S_ISGID bit now.

	without inheritable ACEs.  Explain why.

Corinna Vinschen 97d0449325 Handle permissions a bit closer to POSIX 1003.1e
So far we tweaked ACL_GROUP_OBJ and ACL_MASK values the same way when
creating a file.  We now do what POSIX requires, namely just change
ACL_MASK if it's present, otherwise ACL_GROUP_OBJ.  Note that we only
do this at creation time.  Chmod still tweaks both to create less
surprising results for the unsuspecting user.

Additionally make sure to take umask only into account if no ACL_MASK
value is present.  That has been missed so far.

	* sec_acl.cc (set_posix_access): Perform check for non-existant
	default	ACEs earlier.  Ignore umask also if ACL_MASK is present.
	Only set owner_eq_group if we're actually handling a user entry.

Sebastian Huber 8a5af1a184 Use __machine_*_t_defined for internal types
Newlib defines defaults for internal types via <sys/_types.h> and uses
<machine/_types.h> to let targets define their own type if necessary.

Previously for example

	#ifndef __dev_t_defined
	typedef short __dev_t;
	#endif

However, the __*_t_defined pattern conflicts with the glibc type guard
pattern for user types, e.g. dev_t in this example.  Introduce a
__machine_*_t_defined pattern for internal types (defined by
<machine/_types.h>, used by <sys/_types.h>).  For example

	#ifndef __machine_dev_t_defined
	typedef short __dev_t;

Sebastian Huber 477463a201 Eliminate use of Newlib-specific <machine/types.h>
This change solves a glibc/BSD compatibility problem.

glibc and BSD use double underscore types for internal types.  The Linux
port of Newlib uses some glibc provided internal type definitions which
are not protected by guard defines, e.g. __off_t.  To avoid a conflict
Newlib uses single underscore types for some internal types, e.g.
_off_t.  However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.

The header file <machine/types.h> is Newlib-specific.  It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t.  Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets).  This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target).  Use the standard <sys/_types.h> include throughout.

Move __loff_t defintion to default (non-Linux) <sys/_types.h>.  Define
it via _off64_t to avoid a dependency on the compiler.

Provide the __off_t definition via default (non-Linux) <sys/_types.h>
based on _off_t for all systems except Cygwin.  For Cygwin use _off64_t.
Define off_t via __off_t.

Provide the __pid_t definition via default (non-Linux) <sys/_types.h>.
This prevents a potential __pid_t and pid_t incompatibility.  Add BSD
guard defines for pid_t.

Corinna Vinschen e185421106 strxfrm/wcsxfrm: Always return length of the transformed string
Cygwin's strxfrm/wcsfrm treated a too short output buffer as an error
condition and always returned the size value provided as third parameter.
This is not as it's documented in POSIX.1-2008.  Rather, the only error
condition is an invalid input string(*).

Other than that, the functions are supposed to return the length of the
resulting sort key, even if the output buffer is too small.  In the latter
case the content of the output array is unspecified, but it's the job
of the application to check that the return value is greater or equal to
the provided buffer size.

(*) We have to make an exception in Cygwin:  strxfrm has to call the
    UNICODE function LCMapStringW for reasons outlined in a source comment.
    If the incoming multibyte string is so large that we fail to malloc
    the space required to convert it to a wchar_t string, we have to
    ser errno as well since we have nothing to call LCMapStringW with.

	* nlsfuncs.cc (wcsxfrm): Fix expression computing offset of
	trailing wchar_t NUL.  Compute correct return value even if
	output buffer is too small.
	(strxfrm): Handle failing malloc.  Compute correct return value
	even if	output buffer is too small.

Johannes Schindelin 03ecfb9280 Be truthful about reporting whether readahead is available
In 7346568 (Make requested console reports work, 2016-03-16), code was
introduced to report the current cursor position. It works by using a
pointer that either points to the next byte in the readahead buffer, or
to a NUL byte if the buffer is depleted, or the pointer is NULL.

These conditions are heeded in the fhandler_console::read() method, but
the condition that the pointer can point at the end of the readahead
buffer was not handled properly in the get_cons_readahead_valid()
method.

This poses a problem e.g. in Git for Windows (which uses a slightly
modified MSYS2 runtime which is in turn a slightly modified Cygwin
runtime) when vim queries the cursor position and immediately goes on to
read console input, erroneously thinking that the readahead buffer is
valid when it is already depleted instead. This condition results in an
apparent freeze that can be helped only by pressing keys repeatedly.

The full Git for Windows bug report is here:

	https://github.com/git-for-windows/git/issues/711

Let's just teach the get_cons_readahead_valid() method to handle a
depleted readahead buffer correctly.

Peter Foley e7e6119241 Rename without-mingw-progs to with-cross-bootstrap
Rename without-mingw-progs to with-cross-bootstrap, since it now
disables additional checks that are problematic for cross-compilers.

When cross-compiling a toolchain targeting cygwin, building cygwin1.dll
requires libgcc.
However, building libgcc requires the cygwin headers to be
installed.
Configuring cygwin requries the mingw-crt libraries, which require the
cygwin headers to be installed.
Work around this circular dependency by making the
--with-cross-bootstrap configure option skip cygwin's configure checks
for valid mingw-crt libraries. Cygwin will still properly link against
these libraries if they exist, but this allows configure to succeed even
if the libraries have not been built yet.
Since the mingw-crt libraries only require the cygwin headers to be
installed, this allows us to successfully configure cygwin so that we
can only install the headers without trying to build any
libraries.

Corinna Vinschen 279aaeb5c7 fenv.h: Change fexcept_t to integral type for compatibility
On Linux and in Mingw-w64, fexcept_t is defined as type unsigned short.
There are packages in the wild which rely on the fact that fexcept_t is
an integral type.  We're changing the internal handling to use the bits
just as in GLibc, so only the 6 lowest bits are used to reflect the hw
bits.  We even change the header file guard to reflect GLibc for compatibility.

	* include/fenv.h (_FENV_H): Rename from _FENV_H_ and set to 1 as in
	GLibc's header.
	(fexcept_t): Change to __uint16_t to be an integral type as in GLibc.

Corinna Vinschen 792e51b721 Add missing long double functions to Cygwin
This patch adds the long double functions missing in newlib to Cygwin.
Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l},
isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib.
Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and
fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin.

Cygwin:
	* math: New subdir with math functions.
	* Makefile.in (VPATH): Add math subdir.
	(MATH_OFILES): List of object files collected from building files in
	math subdir.
	(DLL_OFILES): Add $(MATH_OFILES).
	${CURDIR}/libm.a: Add $(MATH_OFILES) to build.
	* common.din: Add new functions from math subdir.
	* i686.din: Align to new math subdir.  Remove functions now commonly
	available.
	* x86_64.din: Ditto.
	* math.h: math.h wrapper to define mingw structs used in some files in
	math subdir.
	* include/cygwin/version.h: Bump API minor version.

newlib:
	* libc/include/complex.h: Add prototypes for complex long double
	functions.  Only define for Cygwin.
	* libc/include/math.h: Additionally enable prototypes of long double
	functions for Cygwin.  Add Cygwin-only prototypes for dreml, sincosl,
	exp10l and pow10l.  Explain why we don't add them to newlib.
	* libc/include/tgmath.h: Enable long double handling on Cygwin.

Yaakov Selkowitz 660f84b15b cygwin: export __getpagesize
The inclusion of <sys/cygwin.h> by <sys/shm.h>, besides causing namespace
pollution, also makes it very difficult to get the WINVER-dependent parts
of the former.  This affects code (such as x11vnc -unixpw_nis) which use
both SysV shared memory (e.g. the X11 MIT-SHM extension) and user password
authentication.

getpagesize is the simplest function to retreive this information, but it
is a legacy function and would also pollute the global namespace. The LSB
lists another form which is in the implementation-reserved namespace:

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
Cygwin_props have been invented to allow switching off the unique

This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.

Other than that, cygwin_props were meant to be used for some other global
settings which never took place.  There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the

Yaakov Selkowitz 84ba25226c Feature test macros overhaul: stdlib.h
Throughout, simplify the C99/C11 conditionals, and replace
__STRICT_ANSI__ with the proper internal POSIX macros.  The _*_r
reentrant functions need not be guarded (and most haven't been) because
such names in the global scope are reserved to the implementation.

atoff is unique to newlib.

dtoa is not actually exported (_dtoa_r is used internally), is
nonstandard, and the declaration conflicts with the code included in
MySQL, NSPR, and SpiderMonkey.

mktemp was removed in POSIX.1-2001.

The qsort_r declarations are reordered so that the GNU version retains
precedence.
