* ssp: Fixes for 64-bitJon Turney2016-02-201-105/+119
| | | | | | | | | | | | | | | Fix various 32/64-bit portability issues in ssp, the single-step profiler, and also build it for 64-bit. This didn't turn out to actually be very useful for what I wanted to use it for, so it's only been lightly tested. It appears that on x86_64, single-step exceptions occur for much more of the code in system DLLs, unlike x86, so ssp may take much, much longer to profile some programs. There is existing code to use breakpoints to mitigate this, but that is currently disabled. Signed-off-by: Jon Turney <jon.turney@dronecode.org.uk>

* Define the newlib version macros in one place: _newlib_version.h.Pieter du Preez2016-02-1714-33640/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the newlib version information needs to be updated in two places: - newlib/acinclude.m4 - newlib/libc/include/sys/features.h The goal of this patch is to: - supply a single location for defining the newlib version information: newlib/acinclude.m4 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__ This is in line with what gcc does for its version macros. See: https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__ and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h, to the newly generated newlib/_newlib_version.h file. Additionally, the __NEWLIB_PATCHLEVEL__ macro was created, for completeness. In order to stay backwards compatible, newlib/_newlib_version.h gets included by newlib/newlib.h and newlib/libc/include/sys/features.h. Note: This patch does _not_ include the modifications to the following files, as these should all be generated any way. *Makefile.in, *aclocal.m4, *configure stamp-* files Signed-off-by: Pieter du Preez <pdupreez@gmail.com>

* Silent relocation truncations considered harmfulMark Geisert2016-02-171-1/+1
| | | | | | | | | | | | This follows up from my msg re GMP-ECM failing its 'make check' on the main list https://cygwin.com/ml/cygwin/2016-02/msg00147.html . There's an error that ought to be reported during dynamic linking if the linked-to address is too far from the relocation site. However the error is not reported if __OPTIMIZE__ was #defined when building the Cygwin DLL. I can't see why optimization settings should affect this.

* Treat ACLs with extra ACEs for Admins and SYSTEM like a trivial ACLCorinna Vinschen2016-01-283-20/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX.1e requires that chmod changes the MASK rather than the GROUP_OBJ value if the ACL is non-trivial. On Windows, especially on home machines, a standard ACL often consists of entries for the user, maybe the group, and additional entries for SYSTEM and the Administrators group. A user calling chmod on a file with bog standard Windows perms usually expects that chmod changes the GROUP_OBJ perms, but given the rules from POSIX.1e we can't do that. However, since we already treat Admins and SYSTEM special in a ACL (they are not used in MASK computations) we go a step in the Windows direction to follow user expectations. If an ACL only consists of the three POSIX permissions, plus entries for Admins and SYSTEM *only*, then we change the permissions of the GROUP_OBJ entry *and* the MASK entry. * fhandler_disk_file.cc (fhandler_disk_file::chmod): Drop unused code. Add special handling for a "standard" Windows ACL. Add comment to explain. * sec_acl.cc (get_posix_access): Allow to return "standard-ness" of an ACL to the caller.

* cygpath: Avoid returning SysWOW64Corinna Vinschen2016-01-211-0/+13
| | | | | | | | | | | | | | | | | | | | | On Cygwin 32 running under WOW64: When case-correcting the path fetched with -S, the underlying Windows function fetching the normalized path returns the real path C:\Windows\SysWOW64 instead of the path redirection enabled C:\Windows\System32 path. This breaks using the result of `cygpath -S' to fetch the POSIX path of the network related files under SYSTEMROOT\drivers\etc. This path is in fact under the *real* C:\Windows\System32 and only mapped into the 32 bit C:\Windows\System32 (aka C:\Windows\SysWOW64) via path redirection. Sounds messy? This patch checks if we're running under WOW64. If so, it changes the path returned by GetSystemDirectoryW from "system32" to "Sysnative". This in turn is changed to "System32" by NtQueryInformationFile, so we're back to what we need. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
