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 :}

Corinna Vinschen 472e5439e7 Fix passwd getting error 1265 when running on newer Windows
On Windows 8.1 and later, the NetUserChangePassword call apparently
doesn't accept the usual "\\server" string anymore, but requires to
use the "domain" instead, otherwise it emits en error code 1265,
ERROR_DOWNGRADE_DETECTED.  Since this is accepted by pre-8.1 as well,
use the domain indiscriminately when calling NetUserChangePassword
from passwd(1).

While at it, do some minor cleanup in passwd.c.

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.

Corinna Vinschen a54bc198b1 Implement correct RLIMIT_STACK handling
* miscfuncs.cc (struct pthread_wrapper_arg): Add member guardsize.
        (pthread_wrapper): Set thread stack guarantee according to guardsize.
        Tweak assembler code so that $rax/$eax is not required by GCC to
        prepare the wrapper_arg value.
        (CygwinCreateThread): Fix deadzone handling.  Drop setting a "POSIX"
        guardpage (aka page w/ PAGE_NOACCESS).  Always use Windows guard
        pages instead.  On post-XP systems (providing SetThreadStackGuarantee)
        always set up stack Windows like with reserved/commited areas and
        movable guard pages.  Only on XP set up stack fully commited if the
        guardpage size is not the default system guardpage size.
        Fill out pthread_wrapper_arg::guardsize.  Improve comments.
        * resource.cc: Implement RSTACK_LIMIT Linux-like.
        (DEFAULT_STACKSIZE): New macro.
        (DEFAULT_STACKGUARD): Ditto.
        (rlimit_stack_guard): New muto.

        (__get_rlimit_stack): Initialize rlimit_stack from executable header
        and return rlimit_stack values under lock.
        (get_rlimit_stack): Filtering function to return useful default
        stacksize from rlimit_stack.rlim_cur value.
        (getrlimit): Call __get_rlimit_stack in RLIMIT_STACK case.
        (setrlimit): Call __set_rlimit_stack in RLIMIT_STACK case.
        * thread.cc (pthread::create): Fetch default stacksize calling
        get_rlimit_stack.
        (pthread_attr::pthread_attr): Fetch default guardsize calling
        wincap.def_guard_page_size.

TCP_NODELAY just like SO_KEEPALIVE and SO_DONTROUTE.
2014-05-05 15:18:17 +00:00
Corinna Vinschen 8e22028339 * fhandler_socket.cc: On x86_64, define u_long as __ms_u_long before
including the windows headers.  Explain why.
	(get_inet_addr): Convert ANY address to LOOPBACK address.  Explain why.
	(fhandler_socket::evaluate_events): Forcibly set SO_ERROR socket option
	in case a connection attempt failed.  Explain why.
	(fhandler_socket::ioctl): Drop x86_64 re-definition of u_long here.
	* fhandler_procnet.cc: On x86_64, define u_long as __ms_u_long before
	including the windows headers.  Explain why.
	* net.cc: Ditto.

Corinna Vinschen ef7e42ec0f * miscfuncs.cc (check_iovec): Allow 0 as valid iovcnt value. 2014-04-23 15:26:14 +00:00
Corinna Vinschen 7ae3e6b3d4 * cygtls.h (TP_NUM_C_BUFS): Raise to 50 to allow SYMLOOP_MAX recursions
path_conv <-> normalize_posix_path, plus a bit of buffer.
	(TP_NUM_W_BUFS): Ditto.
	(class san): Change type of _c_cnt and _w_cnt to unsigned.
	* path.cc (normalize_posix_path): Guard recursion into path_conv
	against tmp_pathbuf overflow.  Generate normalized path in call to
	path_conv.  If the path is valid, replace dst with the normalized_path
	from path_conv call.  Add comment to explain why we're doing this.
	* tls_pbuf.cc (tls_pathbuf::destroy): Only free buffers until the
	first buffer pointer is NULL.
	(tmp_pathbuf::c_get): Simplify error message.
	(tmp_pathbuf::w_get): Ditto.
	* tls_pbuf.h (class tmp_pathbuf): Change type of c_buf_old and w_buf_old
	to unsigned.
	(tmp_pathbuf::check_usage): New inline method to check if we have
	enough tmp_pathbuf buffers left to call a function using tmp_pathbuf
	buffers.
	* tlsoffsets.h: Regenerate.
	* tlsoffsets64.h: Regenerate.
