* Add option to not build mingw programs when cross compiling.Peter Foley2016-03-302-9/+30
| | | | | | | | | | | | Add an option to not require a mingw compiler when bootstrapping a cross toolchain. Defaults to existing behavior. Also update some obsolete macros. winsup/ChangeLog configure.ac: Add option to skip building programs that require mingw. configure: Regenerate. Signed-off-by: Peter Foley <pefoley2@pefoley.com>
* fenv.h: Change fexcept_t to integral type for compatibilityCorinna Vinschen2016-03-302-14/+9
| | | | | | | | | | | | | | | | 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. * fenv.cc (fegetexceptflag): Align to the *flagp's type change. (fesetexceptflag): Ditto.

* Add missing long double functions to CygwinCorinna Vinschen2016-03-29139-33/+10918
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* cygwin: export __getpagesizeYaakov Selkowitz2016-03-294-3/+10
| | | | | | | | | | | | | | | | 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: http://refspecs.linuxfoundation.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/baselib---getpagesize.html Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Drop usage of old-age BSD types in generically used Cygwin headersCorinna Vinschen2016-03-246-47/+47
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Only allow enabled groups as primary groupCorinna Vinschen2016-03-231-6/+45
| | | | | | | | | | | | So far any group in the user's token could be used as primary group. Windows doesn't check if the primary group is enabled or not, it just has no meaning. From a POSIXy point of view it can lead to weird results though. * uinfo.cc (check_token_membership): New static function. (internal_getlogin): Only allow enabled groups as primary group.

* Use 64K buffers for TOKEN_GROUPSCorinna Vinschen2016-03-231-3/+3
| | | | | | | | | | A user token can be up to 64K in size. Using 32K buffers for TOKEN_GROUPS may be insufficient. * uinfo.cc (get_logon_sid): Use 64K buffers for the TOKEN_GROUPS array. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Allocate temporary TOKEN_GROUP arrays using TLSCorinna Vinschen2016-03-231-28/+12
| | | | | | | | | | | | | A user token can be up to 64K in size. The group list might take a lot of that so use tmp_pathbuf allocated space rather than stack space allocted via alloca. In create_token the TOKEN_GROUP was allocated via malloc, but the code is needlessly complicated. Simplify by using tmp_pathbuf as well. * sec_auth.cc (verify_token): Allocate TOKEN_GROUP via tmp_pathbuf. (create_token): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cygwin_props have been invented to allow switching off the unique installation keys in the first place, supposedly for debugging. 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 environment. This patch removes the cygwin_props entirely, including the related settings in cygcheck. cygwin: * cygprops.h: Remove file. * globals.cc (cygwin_props): Remove. * cygheap.cc (init_cygheap::init_installation_root): Drop removing installation key. utils: * cygcheck.cc: Drop including cygprops.h.
