2025-06-18add value for _h_errno in _REENT_INIT(var) for struct, _reentJohannes Rosa1-1/+2
The define '_REENT_INIT' for the case '!_REENT_SMALL' was missing an initializing value for 'int _h_errno'. If code uses the _REENT_INIT() macro to preset a variable of type struct _reent, this led to an issue when compiling with -Wmissing-field-initializers.

2025-03-24getlocalename_l: allow LC_ALL categoryCorinna Vinschen1-2/+9
Following the changes from Austin Group bug https://www.austingroupbugs.net/view.php?id=1741, getlocalename_l() now allows to specify LC_ALL and returns a setlocale-conmpatible LC_ALL locale string. Consequentially we have to raise the size of _reent::_getlocalename_l_buf so there's enough space for the LC_ALL locale string. Guard all different definitions and usages of _getlocalename_l_buf in reent.h with _MB_CAPABLE.

This file was from a specific older FreeBSD version. There have been multiple changes to this file with FreeBSD 14 including breaking changes to the file. Including this file as part of newlib results in not always having the correct version of sys/tree.h for any specific software. RTEMS will manage its use of this file outside of newlib.

#include <locale.h> const char *getlocalename_l(int category, locale_t locobj); Most notably, we need a per-thread space to store the string returned if locobj is LC_GLOBAL_LOCALE. No errors are defined for getlocalename_l. So we can't use buffer allocation which might lead to an ENOMEM error. We have to use a "static" buffer in the per-thread state.

2024-01-29ssp: add support for _FORTIFY_SOURCE=3Christian Franke1-3/+9
If specified, use __builtin_dynamic_object_size() instead of __builtin_object_size() if supported (GCC 12.0 or later). This enables buffer overflow checks if the buffer size is non-const but known during runtime. Use new macro __ssp_bos_known() instead of the (bos(p) != (size_t)-1) checks. The latter is no longer a compile time constant in all cases. This avoids the generation of unused code. Signed-off-by: Christian Franke <christian.franke@t-online.de>

2023-08-15struct _reent: add state for unicode functionsCorinna Vinschen1-0/+16
C23 requires that the unicode functions c16rtomb, c8rtomb, mbrtoc16, mbrtoc32 and mbrtoc8 use their own internal state object. c32rtomb only needs an internal state if the lib supports encoding with shift states, but that's the case for newlib and Cygwin. Only Cygwin implements these functions so add the states objects only for Cygwin for now. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2023-08-07sys/cdefs.h: fix for use __restrict in C++Sebastian Huber1-9/+7
Newlib shares large parts of <sys/cdefs.h> with FreeBSD and received this bug report: https://sourceware.org/pipermail/newlib/2023/020400.html As an extension, GCC and clang offer C99-style restricted pointers in C++ mode: https://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html We notice that this extension is broken when including newlib headers: restricted pointers are treated as ordinary pointers. We traced this to the following section of newlib/libc/include/sys/cdefs.h: /* * GCC 2.95 provides `__restrict' as an extension to C90 to support the * C99-specific `restrict' type qualifier. We happen to use `__restrict' as * a way to define the `restrict' type qualifier without disturbing older * software that is unaware of C99 keywords. */ #if !(__GNUC__ == 2 && __GNUC_MINOR__ == 95) #if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 199901 #define __restrict #else #define __restrict restrict #endif #endif While the GCC __restrict extension was indeed introduced in GCC 2.95, it is not limited to this version; the extension is also not limited to C90: https://gcc.gnu.org/gcc-2.95/c++features.html Rewrite the logic in the header so that __restrict is kept alone when available.

2022-12-08Cygwin: define FILE as struct __sFILE64, not as __sFILECorinna Vinschen1-1/+17
Until Cygwin 3.3.6, we define __LARGE64_FILES unconditionally, so we were using the type __sFILE64 even for 64 bit. That was lazy and wrong. so commit 2902b3a09e0a ("Cygwin: drop requirement to build newlib's stdio64") tried to fix that. Unfortunately this patch forgot to take the exposure of the typename __sFILE64 in userspace into account. This leads to trouble in C++ due to name mangling. Commit 0f376ae22036 tried to fix this by just renaming __sFILE to __sFILE64 by using a macro. While __sFILE and __sFILE64 are the same size, they are not exactly congruent. To avoid backward compatibility problems, make sure to define FILE as the real __sFILE64, and make sure that __sFILE is not defined at all on Cygwin.

2022-07-13Add --enable-newlib-reent-thread-local optionMatt Joyce3-0/+104
By default, Newlib uses a huge object of type struct _reent to store thread-specific data. This object is returned by __getreent() if the __DYNAMIC_REENT__ Newlib configuration option is defined. The reentrancy structure contains for example errno and the standard input, output, and error file streams. This means that if an application only uses errno it has a dependency on the file stream support even if it does not use it. This is an issue for lower end targets and applications which need to qualify the software according to safety standards (for example ECSS-E-ST-40C, ECSS-Q-ST-80C, IEC 61508, ISO 26262, DO-178, DO-330, DO-333). If the new _REENT_THREAD_LOCAL configuration option is enabled, then struct _reent is replaced by dedicated thread-local objects for each struct _reent member. The thread-local objects are defined in translation units which use the corresponding object.
2022-07-13Add _REENT_IS_NULL()Matt Joyce1-0/+2
In a follow up patch, struct _reent is optionally replaced by dedicated thread-local objects. In this case,_REENT is optionally defined to NULL. Add the _REENT_IS_NULL() macro to disable this check on demand.

Add a _REENT_CVTLEN() macro to encapsulate access to the _cvtlen member of struct reent. This will help to replace the struct member with a thread-local storage object in a follow-up patch.
2022-07-13Add _REENT_CLEANUP(ptr)Matt Joyce1-0/+1
Add a _REENT_CLEANUP() macro to encapsulate access to the __cleanup member of struct reent. This will help to replace the struct member with a thread-local storage object in a follow up patch.
