* Cygwin: change virtual_ftype_t to not rely on negative valuesCorinna Vinschen2019-07-229-36/+31
| | | | | | | | | | | | | So far negative values were denoting files, positive values denoting directories. We should prefer a less error prone method. Redefine virtual_ftype_t to contain only positive values and replace checks for negativ or positive values with inline functions virt_ftype_isfile() and virt_ftype_isdir(). Drop outdcated comments referring to numerical virtual_ftype_t values. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: fix /proc/PID/fd return value in error caseCorinna Vinschen2019-07-221-2/+2
| | | | | | | | | | | | commit 2607639992f6 "Improve error handling in /proc/[pid]/ virtual files." changed the return value of the /proc/PID formatting functions to return -1 instead of 0 in the error case to allow a filesize of 0. The patch neglected to change this behaviour for /proc/PID/fd content. This patch fixes that. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: socket files are not lnk special filesKen Brown2019-07-222-3/+5
| | | | | | | | | | | | | Change path_conv::is_lnk_special() so that it returns false on socket files. is_lnk_special() is called by rename2() in order to deal with special files (FIFOs and symlinks, for example) whose Win32 names usually have a ".lnk" suffix. Socket files do not fall into this category, and this change prevents ".lnk" from being appended erroneously when such files are renamed. Remove a now redundant !pc.issocket() from fhandler_disk_file::link().
* Cygwin: remove path_conv::is_fs_device()Ken Brown2019-07-221-2/+2
| | | | It is used only once.
* Cygwin: remove path_conv::is_auto_device()Ken Brown2019-07-222-2/+1
| | | | | | | It is used only once, and the name is supposed to suggest "device that is not based on the filesystem". This intended meaning is clearer if we just replace is_auto_device() by its definition at the place where it's used.
* Cygwin: fhandler_*: remove isdevice() and is_auto_device()Ken Brown2019-07-222-4/+1
| | | | | | isdevice() is used only in the definition of is_auto_device(). And the latter is used only once, in a context where isdevice() always returns true.
* Cygwin: unbreak the build with GCC 7Ken Brown2019-07-192-4/+15
| | | | | | The recent port to GCC 8 used the 'nonstring' attribute, which is unknown to GCC 7. Define and use an 'ATTRIBUTE_NONSTRING' macro instead.
* Cygwin: fix GCC 8.3 'local external declaration' errorsKen Brown2019-07-171-3/+2
| | | | Move external declarations out of function definition.
* Cygwin: fix GCC 8.3 'asm volatile' errorsKen Brown2019-07-171-2/+2
| | | | | | Remove the volatile qualifier, which is no longer allowed outside of the function body. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89585 for discussion.

* Cygwin: sigpending: don't report pending signals for other threadsCorinna Vinschen2019-07-122-2/+10
| | | | | | | | The sigpending mechanism failed to check if the pending signal was a process-wide signal, or a signal for the curent thread. Fix that by adding a matching conditional to wait_sig's __SIGPENDING code. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: return full sigset_t from sig_sendCorinna Vinschen2019-07-125-12/+12
| | | | | | | | | | | | | | | So far sig_send's return type is int. The problem with this is that sig_send returns a sigset_t on __SIGPENDING, and sigset_t is defined as long type. So the function only returns the lower 32 bit of sigset_t, which is fine on 32 bit, but casts away the pending RT signals on 64 bit. Fix this by changing the return type of sig_send to sigset_t, so as not to narrow down the sigset when returning from handling __SIGPENDING. Make sure to cast correctly in all invocations of sig_send. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: honor the O_PATH flag when opening a FIFOKen Brown2019-06-271-1/+10
| | | | | Previously fhandler_fifo::open would treat the FIFO as a reader and would block, waiting for a writer.
* or1k: Avoid write outside setjmp buf & shrink bufMartin Erik Werner2019-06-272-29/+32
| | | | | | | | | | | | Update the offsets used to save registers into the stejmp jmp_buf structure in order to: * Avoid writing the supervision register outside the buffer and thus clobbering something on the stack. Previously the supervision register was written at offset 124 while the buffer was of length 124. * Shrink the jmp_buf down to the size actually needed, by avoiding holes at the locations of omitted registers.

* or1k: Correct longjmp return valueMartin Erik Werner2019-06-271-1/+1
| | | | | | | | | | | Invert equality check instruction to correct the return value handling in longjmp. The return value should be the value of the second argument to longjmp, unless the argument value was 0 in which case it should be 1. Previously, longjmp would set return value 1 if the second argument was non-zero, and 0 if it was 0, which was incorrect.

* Cygwin: timerfd: avoid a deadlockKen Brown2019-06-253-1/+28
| | | | | | | | | Add a function timerfd_tracker::enter_critical_section_cancelable, which is like enter_critical_section but honors a cancel event. Call this when a timer expires while the timerfd thread is in its inner loop. This avoids a deadlock if timerfd_tracker::dtor has entered its critical section and is trying to cancel the thread.

* Support calculation of pointer size for __int20__ type in _intsup.hJozef Lawrynowicz2019-06-251-0/+4
| | | | | | | | | GCC r272640 modifies the MSP430 target to use "__int20__" for PTRDIFF_TYPE (and therefore INTPTR_TYPE) instead of "__int20". To support the calculation of pointer size in newlib/libc/include/sys/_intsup.h, definitions for __int20__ need to be added.
* Cygwin: Implement sched_[gs]etaffinity()Mark Geisert2019-06-2411-5/+389
| | | | | | | | | This patch set implements the Linux syscalls sched_getaffinity, sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np. Linux has a straightforward view of the cpu sets used in affinity masks. They are simply long (1024-bit) bit masks. This code emulates that view while internally dealing with Windows' distribution of available CPUs among processor groups.
* Cygwin: FIFO: minor cleanupKen Brown2019-06-232-7/+7
| | | | | | Don't use a label with the same name as a variable. Also fix indentation in fhandler.h.
* Cygwin: FIFO: slightly change the use of write_readyKen Brown2019-06-231-1/+2
| | | | | | | Make it a manual reset event. It's only used once to allow a reader to open, and there's no reason to ever reset it. Defensively set it when a client connection is recorded, even though it should be set by the writer that connected.
* Cygwin: FIFO: remove fifo_client_handler::connect_evtKen Brown2019-06-232-16/+15
| | | | | It's not needed. Instead just create and use an event in fhandler_fifo::listen_client_thread.
* Cygwin: FIFO: simplify raw_readKen Brown2019-06-231-19/+31
| | | | | | Call NtReadFile directly instead of calling fhandler_base::raw_read. In addition to being simpler, this gives us access to the return value from NtReadFile.
* Cygwin: FIFO: improve termination of the listen_client threadKen Brown2019-06-232-15/+55
| | | | | | | | | Add a method fifo_client_handler::pipe_state that queries Windows for the state of a pipe instance. Use this to help terminate the listen_client thread cleanly. If the last client handler is useless, delete it instead of declaring it invalid.
* Cygwin: FIFO: avoid deadlock when closingKen Brown2019-06-231-0/+3
| | | | | | | | fhandler_fifo::close could be called from a signal handler or another thread at a time when another function is holding the fifo_client lock. This could prevent the listen_client thread from acting on the thread termination event. Avoid a deadlock by calling fifo_client_unlock at the beginning of fhandler_fifo::close.
* Cygwin: FIFO: clean up locksKen Brown2019-06-231-8/+17
| | | | | Make sure to use the fifo_client lock when (and only when) it is needed.
* Cygwin: FIFO: add some error checkingKen Brown2019-06-232-4/+11
| | | | | Change the return type of fhandler_fifo::delete_client_handler from void to int so that we can report errors.
* Cygwin: FIFO: fix signal handling in raw_read and raw_writeKen Brown2019-06-231-31/+54
| | | | | | cygwait wasn't being called correctly. Also do some minor cleanup in raw_read and raw_write.
* Rename <xlocale.h> back to <sys/_locale.h>Corinna Vinschen2019-06-1414-14/+23
| | | | | | | | | | | | | | | | | | | libX11 provides <X11/Xlocale.h>. The build of libX11 itself adds include/X11 to the compiler's include path. This results in a name collision with /usr/include/xlocale.h on case-insensitive filesystems. Commit 90e35b1eb3df renamed sys/_locale.h to xlocale.h in March 2017 under the assumption that we should provide the locale_t type in the same file as on Linux, FreeBSD, and Darwin. A few weeks later (June 2017), glibc removed the xlocale.h file in favor of bits/types/locale_t.h, which shouldn't be included directly anyway. For reference and the reasoning, see https://sourceware.org/git/?p=glibc.git;a=commit;h=f0be25b6336d Given the above, revert 90e35b1eb3df4070e68afc5e7060665214d586be and fix additional usage of xlocale.h.

* Fix __getreent stack calculations for AMD GCNJeff Johnston2019-06-071-6/+6
| | | | | | | | From: Andrew Stubbs <ams@codesourcery.com> Fix a bug in which the high-part of 64-bit values are being corrupted, leading to erroneous stack overflow errors. The problem was only that the mixed-size calculations are being treated as signed when they should be unsigned.
* Add gfortran support for AMD GCNJeff Johnston2019-06-0710-3/+212
| | | | | | | | | | From: Kwok Cheung Yeung <kcy@codesourcery.com> This patch adds enough support for constructors/destructors and OS functions to be able to link and run gfortran programs on AMD GCN. There's no actual ability to do I/O operations on this targets, besides "write" to stdout and stderr, so most of the functions are just stubs.

* sys/sys: further adoption of SPDX licensing ID tags.pfg2019-06-071-0/+2
| | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
* Cygwin: map beyond EOF on 64 bit and WOW64 as wellCorinna Vinschen2019-06-051-11/+24
| | | | | | | | | | | | | | | | | | 32 bit Cygwin performs a POSIX-compatible mapping after EOF which is not supported in this form on Windows. The 64 bit Windows kernel never supported the AT_ROUND_TO_PAGE mapping flag, so we couldn't page-aligned map the space right after the file's EOF. So mapping beyond EOF was disabled in 64 bit Windows and WOW64. However, if mmap works, a matching munmap should work as well, *and* it should not accidentally unmap unrelated memory. Therefore we enable mapping beyond EOF on 64 bit as well. Since that mapping is always 64K aligned, the are between the last file page and the next 64K allocation boundary will be unallocated. There's no way around that. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* mkdir: always check-for-existenceBen Wijen2019-06-051-1/+3
| | | | | | | | | When using NtCreateFile when creating a directory that already exists, it will correctly return 'STATUS_OBJECT_NAME_COLLISION'. However using this function to create a directory (and all its parents) a normal use would be to start with mkdir(‘/cygdrive/c’) which translates to ‘C:\’ for which it'll instead return ‘STATUS_ACCESS_DENIED’.
* cygcheck: expand common_apps listYaakov Selkowitz2019-06-041-1/+16
| | | | | | | | | An increasing number of tools are being included in Windows which have the same names as those included in Cygwin packages. Indicating which one is first in PATH can be helpful in diagnosing behavioural discrepencies between them. Also, fix the alphabetization of ssh.
* Cygwin: Allow accessing 48 bit address space in Windows 8.1 or laterCorinna Vinschen2019-06-044-5/+20
| | | | | | | | | | | | | | | | | 64 bit Windows started out with a 44 bit address space due to a restriction of the AMD64 CPUs at the time. Starting with Windows 8.1, these CPUs are not supported anymore and Windows switched to the full 48 bit address space supported by AMD64. Cygwin didn't follow suit yet so mmaps are still restricted to the lower 44 bit address space. Fix that by using a system-specific upper address for mmap allocations, 44 bit up to Windows 8, 48 bit starting with Windows 8.1. While at it, move the heap by another 8 Gigs to leave some space for a potential extension of DLL address space, and restrict the mmap lower address so the heap can grow to 32 Gigs before colliding with mmaps.
* Cygwin: fork: Remember child not before success.Michael Haubenwallner2019-06-031-15/+16
| | | | | | | | Do not remember the child before it was successfully initialized, or we would need more sophisticated cleanup on child initialization failure, like cleaning up the process table and suppressing SIGCHILD delivery with multiple threads ("waitproc") involved. Compared to that, the potential slowdown due to an extra yield () call should be negligible.
* Cygwin: fork: Always pause child after fixups.Michael Haubenwallner2019-06-031-10/+9
| | | | | | | | | | Pause the child process after performing fork fixups even if there were no dynamically loaded dlls with extra data/bss transfers to wait for. This allows the parent process to cancel the current fork call even if the child process was successfully initialized already. This is a preparation for when the parent does remember the child no earlier than after successful child initialization.
