for KB 2393802. Adjust comments throughout.
(struct _FAST_CWD_OLD): Rename former definition.
(cwdstuff::override_win32_cwd): Check if the OS is using the old or the
new FAST_CWD structure layout and handle accordingly.
(cygheap_init): Just zero cygheap structure.
* cygwin.sc: Keep 16 byte alignment but drop all other alignments related to
cygheap. Eliminate unused __cygheap_end1.
and __BYTE_ORDER into ...
* include/bits/endian.h: New file.
* include/arpa/nameser_compat.h: Include endian.h rather than defining
BYTE_ORDER here.
* include/asm/byteorder.h: Include bits/endian.h. Drop definition of
__LITTLE_ENDIAN.
* include/netinet/ip.h: Include bits/endian.h. Drop definitions of
BIG_ENDIAN, LITTLE_ENDIAN, and BYTE_ORDER. Use underscored variants
of aforementioned constants.
* include/netinet/tcp.h: Ditto.
* include/sys/param.h: Drop disabled definitions of BIG_ENDIAN,
LITTLE_ENDIAN, and BYTE_ORDER.
* include/netinet/ip.h: Reformat. Define setsockopt IP_TOS options
matching recent RFCs. Tweak comments.
* errno.cc (__xpg_strerror_r): New function.
(strerror_r): Update to copy newlib's fixes.
(strerror): Set errno on failure.
(_sys_errlist): Cause EINVAL failure for reserved values.
* cygwin.din: Export new function.
* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Combine
this into minor 236.
erroneous premature return after collecting truncated multibyte
sequence in trunc_buf. Rather fall through to printing routine.
Fix return value to take trunc_buf content into account. Improve
comments.
(fhandler_socket::bind): Change comment to explain setting the
SO_EXCLUSIVEADDRUSE socket option. Remove code which checks for
address in use.
* net.cc (cygwin_setsockopt): Never set SO_REUSEADDR option. Improve
comment to compensate for the deleted comment in fhandler_socket::bind.
* wincap.cc: Throughout, drop has_enhanced_socket_security from wincaps.
* wincap.h (struct wincaps): Drop has_enhanced_socket_security flags
and method.
* winf.h: Move definitions of _P_PATH_TYPE_EXEC and _P_MODE from here...
* pinfo.h: ...to here.
(_P_PATH_TYPE_EXEC): Redefine to be bigger than _P_SYSTEM.
(_P_MODE): Redefine so as not to mask out _P_SYSTEM.
* spawn.cc (spawnlp): Add _P_PATH_TYPE_EXEC flag in call to spawnve.
(spawnlpe): Ditto.
(spawnvp): Ditto.
* exec.cc (execvp): Call spawnve with _P_PATH_TYPE_EXEC flag
from here.
(execvpe): Ditto.
* spawn.cc (spawn_guts): Filter _P_PATH_TYPE_EXEC from mode and
store in p_type_exec. Call av::fixup with addtional p_type_exec
argument.
(spawnve): Check for filtered mode.
(spawnvpe): Add _P_PATH_TYPE_EXEC flag when calling spawnve.
(av::fixup): Accept additional bool parameter p_type_exec. Only check
for script if p_type_exec is true.
* winf.h (_P_PATH_TYPE_EXEC): Define.
(_P_MODE): Define.
(av::fixup): Declare with additional bool parameter.
PC_SYM_NOFOLLOW_REP flag is set.
(cygwin_conv_path): Set PC_SYM_NOFOLLOW_REP flag when converting from
POSIX to Win32.
* path.h (enum pathconv_arg): Define PC_SYM_NOFOLLOW_REP flag.
(fhandler_proc::fill_filebuf): Handle return value of 0 from format
function as error.
(format_proc_stat): Set errno when returning 0 size.
(format_proc_partitions): Rewrite method to fetch partition info.
(class fhandler_dev_floppy): Convert partitions to part_t pointer.
Add lock_partition method.
* fhandler_floppy.cc (fhandler_dev_floppy::lock_partition): New method
to implement ondemand partition locking.
(fhandler_dev_floppy::write_file): Call lock_partition from here if
writing failed due to a potential write restriction on a disk
partition.
(fhandler_dev_floppy::open): Don't lock partitions here.
(fhandler_dev_floppy::close): Keep track of partition handle reference
count. Close handles and remove partitions pointer ony if count is 0.
(fhandler_dev_floppy::dup): Just copy partitions pointer and increment
reference count.
