| | | | | | | | | | | | | | | * sec_acl.cc: Change preceeding comment explaining new-style ACLs. Describe how to generate deny ACEs in more detail. Accommodate the fact that a NULL deny ACE is used for {DEF_}CLASS_OBJ, rather than a special Cygwin ACE. Improve further comments. (CYG_ACE_NEW_STYLE): Define. (get_posix_access): Change from Cygwin ACE to NULL deny ACE. Fix CLASS_OBJ handling to generate CLASS_OBJ and DEF_CLASS_OBJ from a single NULL deny ACE if the inheritance flags say so. * sec_helper.cc (well_known_cygwin_sid): Remove. * security.h (well_known_cygwin_sid): Drop declaration.

* Compile exceptions.cc with -fno-omit-frame-pointer on x86Jon TURNEY2015-04-072-52/+13
| | | | | | | | | | | | | | Selectively using -fomit-frame-pointer when -O is used doesn't make sense anymore, apparently since gcc 4.6, -O implies -fomit-frame-pointer. exceptions.cc must be compiled with -fno-omit-frame-pointer on x86, as it uses RtlCaptureContext, which requires a frame pointer. * Makefile.in : Remove setting -fomit-frame-pointer for compiling various files, it is already the default. Set -fno-omit-frame-pointer for exceptions.cc on x86. Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk>

* Try to make sure struct _mcontext is 16-byte alignedJon TURNEY2015-04-023-3/+8
| | | | | | | | | | | | | | | | | | On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state. fxsave requires that the destination address is 16-byte aligned, or it will fault. CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with struct _mcontext. Rearrange ucontext_t so that it's struct _mcontext element is also correctly aligned. * include/cygwin/signal.h (struct __mcontext): 16-byte align. * include/sys/ucontext.h (ucontext_t): Ditto.
