Corinna Vinschen 85db21730b ldd: Handle executable relocation when setting breakpoint
set_entry_point_break() uses GetModuleInformation to fetch the
address of the exe's entry point.  However, just as with
lpStartAddress from the CREATE_PROCESS_DEBUG_EVENT event, the
returned address is only computed from the PE file header.  It's
not actually the entry point in memory, if the executable is
relocated (ASLR).  See
https://msdn.microsoft.com/en-us/library/windows/desktop/ms684229(v=vs.85).aspx

Convert this to using the info from CREATE_PROCESS_DEBUG_EVENT
combined with the offset from the PE file header's  AddressOfEntryPoint
to deal with relocation.

Corinna Vinschen 9f54ceadae ldd: terminate process on hitting breakpoint
So far ldd terminates the inferior process as soon as some thread
is started.  Apparently threads are started from even ntdll.dll
before the main thread of the application is started.  As a result
the dll list is cut short since ldd terminates prematurely.

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
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

Jon Turney 658caa7640 ssp: Fixes for 64-bit
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.

Corinna Vinschen 79b1b77b1f cygpath: Avoid returning SysWOW64
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.

Corinna Vinschen bc444e5aa4 Reapply POSIX ACL changes.
- New, unified implementation of POSIX permission and ACL handling.  The
    new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and
    they allow to inherit the S_ISGID bit.  ACL inheritance now really
    works as desired, in a limited, but theoretically equivalent fashion
    even for non-Cygwin processes.

    To accommodate Windows default ACLs, the new code ignores SYSTEM and
    Administrators group permissions when computing the MASK/CLASS_OBJ
    permission mask on old ACLs, and it doesn't deny access to SYSTEM and
    Administrators group based on the value of MASK/CLASS_OBJ when
    creating the new ACLs.

    The new code now handles the S_ISGID bit on directories as on Linux:
    Setting S_ISGID on a directory causes new files and subdirs created
    within to inherit its group, rather than the primary group of the user
    who created the file.  This only works for files and directories
    created by Cygwin processes.

Jon TURNEY 5c4129d937 Improve strace to log most Windows debug events
Not sure if this is wanted, but on a couple of occasions recently I have been
presented with strace output which contains an exception at an address in an
unknown module (i.e. not in the cygwin DLL or the main executable), so here is a
patch which adds some more information, including DLL load addresses, to help
interpret such straces.

v2:
Use NtQueryObject() for HANDLE -> filename conversion
Add new '-e' option to toggle this additional logging

2015-06-07  Jon Turney  <jon.turney@dronecode.org.uk>

	* strace.cc (proc_child): Log process and thread create and exit,
	and DLL load and unload.
	(GetFileNameFromHandle): New function.
