Corinna Vinschen eb4bfe4621 cygwin: block devices: fix file offset after short writes
When reading/writing block devices, Cygwin emulates Linux, providing
a byte-exact file position, albeit the underlying device drivers don't.

Unfortunately this only worked correctly for reading.  The raw_write
method failed to revalidate the buffer after the read-modify-write
cycle in case len is not a multiple of the sector length.  This in
turn resulted in lseek reporting a wrong file pointer.

Also, fix a condition for invalidating the buffer after writing from
a remaining read buffer.

Corinna Vinschen 33297d810d Cygwin: dlfcn: Fix reference counting
The original dll_init code was living under the wrong assumption that
dll_dllcrt0_1 and in turn dll_list::alloc will be called for each
LoadLibrary call.  The same wrong assumption was made for
cygwin_detach_dll/dll_list::detach called via FreeLibrary.

In reality, dll_dllcrt0_1 gets only called once at first LoadLibrary
and cygwin_detach_dll once at last FreeLibrary.

In effect, reference counting for DLLs was completely broken after fork:

  parent:
    l1 = dlopen ("lib1");  // LoadLibrary, LoadCount = 1
    l2 = dlopen ("lib1");  // LoadLibrary, LoadCount = 2

    fork ();               // LoadLibrary in the child, LoadCount = 1!
      child:
        dlclose (l1);      // FreeLibrary actually frees the lib
        x = dlsym (l2);    // SEGV

* Move reference counting to dlopen/dlclose since only those functions
  have to keep track of loading/unloading DLLs in the application context.

* Remove broken accounting code from dll_list::alloc and dll_list::detach.

* Fix error handling in dlclose.

David Allsopp 226f69422a Preserve order of dlopen'd modules in dll_list::topsort
This patch alters the behaviour of dll_list::topsort to preserve the
order of dlopen'd units.

The load order of unrelated DLLs is reversed every time fork is called,
since dll_list::topsort finds the tail of the list and then unwinds to
reinsert items. My change takes advantage of what should be undefined
behaviour in dll_list::populate_deps (ndeps non-zero and ndeps and deps
not initialised) to allow the deps field to be initialised prior to the
call and appended to, rather than overwritten.

All DLLs which have been dlopen'd have their deps list initialised with
the list of all previously dlopen'd units. These extra dependencies mean
that the unwind preserves the order of dlopen'd units.

The motivation for this is the FlexDLL linker used in OCaml. The FlexDLL
linker allows a dlopen'd unit to refer to symbols in previously dlopen'd
units and it resolves these symbols in DllMain before anything else has
initialised (including the Cygwin DLL). This means that dependencies may
exist between dlopen'd units (which the OCaml runtime system
understands) but which Windows is unaware of. During fork, the
process-level table which FlexDLL uses to get the symbol table of each
DLL is copied over but because the load order of dlopen'd DLLs is
reversed, it is possible for FlexDLL to attempt to access memory in the
DLL before it has been loaded and hence it fails with an access
violation. Because the list is reversed on each call to fork, it means
that a subsequent call to fork puts the DLLs back into the correct
order, hence "even" invocations of fork work!

An interesting side-effect is that this only occurs if the DLLs load at
their preferred base address - if they have to be rebased, then FlexDLL
works because at the time that the dependent unit is loaded out of
order, there is still in memory the "dummy" DONT_RESOLVE_DLL_REFERENCES
version of the dependency which, as it happens, will contain the correct
symbol table in the data section. For my tests, this initially appeared
to be an x86-only problem, but that was only because the two DLLs on x64
should have been rebased.

Corinna Vinschen e3ccb68610 Don't check directories always case-insensitive in rename(2)
Long-standing problem in one of the corner cases of rename(2):
If we rename a directory a check is performed to see if newpath is
identical to oldpath or a subdir of oldpath. This check is
(accidentally? no hints anywhere in ChangeLogs or code) performed
case-insensitive for as long as we use Unicode paths and NT functions.
This leads to the problems described in
https://cygwin.com/ml/cygwin/2016-09/msg00264.html

Change this to be conditional case-sensitive as all other checks but
let's take this with a grain of salt.  There may be corner-cases in
this corner-case which require to chek parts of the path always
case-insensitive.  Off the top of my head I can't construct such a
case but that's no proof they don't exist :}

use the domain indiscriminately when calling NetUserChangePassword
from passwd(1).

Jon Turney fdb7df230d Add pthread_getname_np and pthread_setname_np
This patch adds pthread_getname_np and pthread_setname_np.

These were added to glibc in 2.12[1] and are also present in some form on
NetBSD and several UNIXes.

The code is based on NetBSD's implementation with changes to better match
Linux behaviour.

Implementation quirks:

* pthread_setname_np with a NULL pointer segfaults (as linux)

* pthread_setname_np returns ERANGE for names longer than 16 characters (as
linux)

* pthread_getname_np with a NULL pointer returns EFAULT (as linux)

* pthread_getname_np with a buffer length of less than 16 returns ERANGE (as
linux)

* pthread_getname_np truncates the thread name to fit the buffer length.
This guarantees success even when the default thread name is longer than 16
characters, but means there is no way to discover the actual length of the
thread name. (Linux always truncates the thread name to 16 characters)

* Changing program_invocation_short_name changes the default thread name (on
linux, it has no effect on the default thread name)

I'll leave it up to you to decide if any of these matter.

This is implemented via class pthread_attr to make it easier to add
pthread_attr_[gs]etname_np (present in NetBSD and some UNIXes) should it
ever be added to Linux (or we decide we want it anyway).

Eric Blake 6795ef7d37 Fix 32-bit SSIZE_MAX
POSIX requires that SSIZE_MAX have the same type as ssize_t, but
on 32-bit, we were defining it as a long even though ssize_t
resolves to an int.  It also requires that SSIZE_MAX be usable
via preprocessor #if, so we can't cheat and use a cast.

If this were newlib, I'd have had to hack _intsup.h to probe the
qualities of size_t (via gcc's __SIZE_TYPE__), similar to how we
already probe the qualities of int8_t and friends, then cross our
fingers that ssize_t happens to have the same rank (most systems
do, but POSIX permits a system where they differ such as size_t
being long while ssize_t is int).  Unfortunately gcc gives us
neither __SSIZE_TYPE__ nor __SSIZE_MAX__.  On the other hand, our
limits.h is specific to cygwin, so we can just shortcut to the
correct results rather than being generic to all possible ABI.
