(class child_info): Add an element.
* cygheap.cc (init_cheap): Allocate cygwin heap in shared memory area.
(cygheap_fixup_in_child): Map cygwin heap, passed from parent via shared memory
into correct address.
(cygheap_setup_for_child): New function.
* cygheap.h: Declare new functions.
* dcrt0.cc (dll_crt0_1): Accomodate new cygheap_fixup_in_child arguments.
Avoid protecting subproc_ready unless it is spawn/nowait.
* fork.cc (fork_parent): Use new cygheap_setup_for_child function to setup
cygwin heap info. Close passed cygheap shared memory handle.
* spawn.cc (spawn_guts): Ditto. Also, reorganize to avoid synchronization
between parent and child in non-P_OVERLAY case.
* sigproc.cc (wait_sig): Only signal subproc_ready when execing.
* sec_acl.cc (setacl): Never set DELETE permission. Set
FILE_DELETE_CHILD only on readable and executable directories.
* sec_helper.cc: Add constructor for `well_known_null_sid'.
* security.cc (get_nt_attribute): Set S_ISVTX for directories if
FILE_WRITE_DATA and FILE_EXECUTE but not FILE_DELETE_CHILD is set.
Add evaluation of S_ISVTX, S_ISGID and S_ISUID from NULL ACE.
(alloc_sd): Never set DELETE permission. Set FILE_DELETE_CHILD
only on readable and executable directories.
Add creation of NULL ACE for S_ISVTX, S_ISGID and S_ISUID permissions.
* security.h: Add extern declaration for `well_known_null_sid'.
* path.cc (path_conv::check): Add signal protection here since retrieving info
about remote shares can take some time.
* path.h (check_null_empty_str_errno): Convert to a function prototype.
* path.cc (check_null_empty_str): Move to miscfuncs.cc.
* miscfuncs.cc (check_null_empty_str_errno): New function.
(__check_null_invalid_struct): Ditto.
(__check_null_invalid_struct_errno): Ditto.
(check_null_empty_str): Change from VirtualQuery to IsBadWritePtr.
* thread.cc (check_valid_pointer): Ditto.
* resource.cc (getrlimit): Use check_null_invalid_struct macro for checking
validity of pointer.
(setrlimit): Ditto.
being read for executable test since we could be checking for less than that.
* syscalls.cc (stat_worker): Try opening the file the "correct" way first so
that #! processing can potentially happen. If that fails, then use "query
open" method.
* spawn.cc (spawn_guts): Delay processing of signal until after we've notified
parent about reparenting.
* thread.cc (pthread_cond::TimedWait): Check for WAIT_TIMEOUT as well as
WAIT_ABANDONED.
(__pthread_cond_timedwait): Calculate a relative wait from the abstime
parameter.
(setup_handler): Move actions after a successful interrupt to interrupt_setup.
* fork.cc (vfork): Augment debugging output.
* sigproc.cc (proc_subproc): Ditto.
* spawn.cc (spawn_guts): Ditto. Correctly fill out progname when spawn
NO_WAIT. Call signal handler when a signal arrives.
* sigproc.h: Declare a function.
* thread.cc (__pthread_cond_timedwait): Lock the waiting mutex before
the condition protect mutex to avoid deadlocking. (Found by Greg Smith).
(__pthread_cond_wait): Ditto.
function.
* fhandler.h: Declare it.
* fhandler_socket.cc (fhandler_socket::create_secret_event): Don't
signal secret event immediately.
(fhandler_socket::check_peer_secret_event): Do it after peer event
was opened.
* net.cc (cygwin_connect): Or if socket is non-blocking.
(cygwin_accept): Ditto.
