* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Always allocate main thread stack from pthread stack area on x86_64.Corinna Vinschen2015-12-071-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc: Semi-revert commit 12743c2d5d2721f3a80b4d7671a349be03c1f520. (dll_crt0_0): Drop setting wow64_needs_stack_adjustment on 64 bit. (_dll_crt0): Split out 64 bit code again and always create new main thread stack, unless forked off from the non main thread in the parent. Call create_new_main_thread_stack with parent stack commitsize if started from the parent's main thread. Only call child_info_fork::alloc_stack for the latter case on 64 bit. Slightly rearrange moving rsp and rbp to new stack and document how. Revert 32 bit wow64 handling to its former self. * miscfunc.cc (create_new_main_thread_stack): Take a commitsize parameter and use it if it's not 0. Don't set _main_tls here, it's done in the caller _dll_crt0 anyway. Return stackbase - 16 bytes, rather than stacklimit (which was very wrong anyway). * miscfuncs.h (create_new_main_thread_stack): Accommodate declaration to aforementioned change. * wincap.h (wincaps::has_3264_stack_broken): Remove element. * wincap.cc: Ditto, throughout. * wow64.cc: Semi-revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520 but keep architecture-agnostic type changes intact. Fix formatting. * wow64.h: Revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: Fix x86_64 memcpy/memset for n > 2GBCorinna Vinschen2015-07-291-19/+173
| | | | | | | | | | | | | | | | https://cygwin.com/ml/cygwin/2015-07/msg00344.html: RtlFillMemory and RtlCopyMemory only work for size values up to 2GB. Fix this problem by using NetBSD code for memset and memcpy. Add entry points for memmove, wmemset, wmemmove, wmemcpy. Thanks to Roman Petrovski <RPetrovski@illumina.com> for pointing this out. * miscfuncs.cc (memset): x86_64 only: Implement in assembler. (memmove,memcpy): x86_64 only: Ditto.

(CygwinCreateThread): Fix deadzone handling. Drop setting a "POSIX" guardpage (aka page w/ PAGE_NOACCESS). Always use Windows guard pages instead. On post-XP systems (providing SetThreadStackGuarantee) always set up stack Windows like with reserved/commited areas and movable guard pages.
