* sys/time.h: Change visibility of gettimeofday.Corinna Vinschen2016-06-201-1/+2
| | | | | | | gettimeofday is currently guarded with __MISC_VISIBLE || __XSI_VISIBLE. However, gettimeofday should be always visible, as in GLibc. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Feature test macros: ctermid, cuseridYaakov Selkowitz2016-05-231-0/+4
| | | | | | | | | | The proper location for these functions has always been <stdio.h>, however XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid declaration in <unistd.h> was made optional and obsolete in SUSv4.

* Make sure to have full configuration info in sys/_types.h.Corinna Vinschen2016-05-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The following testcase: $ cat > test.c <<EOF #include <sys/select.h> #include <sys/time.h> EOF $ gcc -c test.c emits the following error: /usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor e ‘_fpos64_t’ _fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int)); ^ The reason is that the load order from sys/select.h includes sys/_types.h before sys/config.h has been included from anywhere else. sys/_types.h defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in this scenario. So sys/_types.h has to make sure to get the configuration info by itself. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Always provide register_t via <sys/types.h>Sebastian Huber2016-04-211-4/+2

* Resurrect <machine/types.h> for <sys/types.h>Sebastian Huber2016-04-212-11/+4
| | | | | | | | | | | Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib targets may provide an own version of <machine/types.h> in their machine directory to add custom user types for <sys/types.h>. Check the _SYS_TYPES_H header guard to prevent a direct include of <machine/types.h>, since the <machine/types.h> file is a Newlib speciality.

* Provide __size_t via <sys/_types.h>Sebastian Huber2016-04-152-2/+17
| | | | | | | | | | | | | | | | | | | | | Various FreeBSD source and header files need a typedef __size_t via <sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses #if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \ || defined(__DragonFly__) \ || defined(__FreeBSD_kernel__) /* __size_t is a typedef on FreeBSD 5, must not trash it. */ #elif defined (__VMS__) /* __size_t is also a typedef on VMS. */ #else #define __size_t #endif and therefore defines __size_t on Newlib targets which would trash a __size_t typedef. Include <stddef.h> before <sys/_types.h> in <sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* Use __machine_*_t_defined for internal typesSebastian Huber2016-04-151-14/+24
| | | | | | | | | | | | | | | | | | | | | | 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; #endif Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* Eliminate use of Newlib-specific <machine/types.h>Sebastian Huber2016-04-137-10/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cygwin: make POSIX/XSI version macros dependent on feature test macrosYaakov Selkowitz2016-04-041-10/+37
| | | | | | | | | | | | | Each version of SUS specifies a different value for _POSIX_VERSION, _POSIX2_VERSION, and _XOPEN_VERSION. glibc also changes the value of the other _POSIX2_ variables but not the _POSIX_* variables. _POSIX_TIMERS should be set to a version number, not just 1. The _POSIX_V7_* macros were missing, which was not noticed because the V6 values were aliased in sysconf (<unistd.h>). Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Drop usage of old-age BSD types in generically used Cygwin headersCorinna Vinschen2016-03-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | u_char, u_short, u_int, u_long are BSD-only types. Remove them from Cygwin headers which are supposed to be used in a non-BSD scenario. Drop special Cygwin handling of those types in sys/types.h. newlib: * libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop Cygwin exception. cygwin: * fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change in include/asm/socket.h. Continue using u_long since that's the MS type here. * include/asm/socket.h: Since the type given in _IOR/_IOW macros is only used for its sizeof, replace u_long with equivalent long. * netdb.h (getnetbyaddr): Fix prototype. * netinet/ip.h: Replace old BSD-only types with generically defined old BSD types (u_char -> u_int8_t, etc). * netinet/tcp.h: Ditto. * netinet/udp.h: Ditto.

They are always defined when using Glibc headers so we follow suit. newlib: * libc/include/sys/types.h: Drop outdated __INTTYPES_DEFINED__ macro.

* Feature test macros overhaul: C++ TR1Yaakov Selkowitz2016-03-231-5/+5
| | | | | | | | | | | | While C++11 was the first version of the standard to use C99 functionality, TR1 (for C++03) also does, and G++ does not distinguish between C++98 and C++03, or when TR1 is in use. Therefore, while not strictly correct for "pure" C++98, enabling C99 for all C++ usage is the simplest solution (and much better than always using -D_GNU_SOURCE as on Linux).

* Add arc4random() etc. from OpenBSD 5.8Sebastian Huber2016-03-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | According to the OpenBSD man page, "A Replacement Call for Random". It offers high quality random numbers derived from input data obtained by the OpenBSD specific getentropy() system call which is declared in <unistd.h> and must be implemented for each Newlib port externally. The arc4random() functions are used for example in LibreSSL and OpenSSH. Cygwin provides currently its own implementation of the arc4random family. Maybe it makes sense to use this getentropy() implementation: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libcrypto/crypto/getentropy_win.c?rev=1.4&content-type=text/x-cvsweb-markup * libc/include/stdlib.h (arc4random): Declare if __BSD_VISIBLE.
