2016-12-23Bump release to 2.5.0 for yearly snapshot.newlib-2_5_0Jeff Johnston
2016-12-22This is an attempt to fix the problem described here:Jeff Johnston
https://sourceware.org/ml/newlib/2016/msg01139.html https://gcc.gnu.org/ml/gcc/2016-12/msg00010.html There is no change if libtool is used. Some run-time support libraries provided by GCC (e.g. libgomp) use configure checks to detect certain features, e.g. availability of thread-local storage. The configure script generates a test program and tries to compile and link it. It should use target libraries and startfiles of the build tree if available and not random ones from the installation prefix for this procedure. The search directories specified by -B are a bit special, see for_each_path() in gcc.c of the GCC sources. First a search is performed on all search paths with the multilib directory appended (if desired), then a second search is performed on demand with the base directory only. For each multilib there is a "newlib" subdirectory. This directory is specified by a -B option for the support libraries. In order to find the newlib artifacts (ctr0.o, libc.a, libg.a and libm.a) they must be located in a proper multilib subdirectory withing the build directory.

__sinit initialises some common file descriptors as line buffered and relies on the first users of such FDs to call __smakebuf_r. If __smakebuf_r realises there's no space for a buffer (malloc returns NULL), it makes them unbuffered. However, while setting the __SNBF bit, it doesn't clear the __SLBF bit in the flags. Depending on the order in which functions check buffering flags in the FD, sometime they assume it's line buffered (e.g. __sfvwrite_r), trashing application memory that's not really been allocated to them. This patch solves the problem by clearing the unbuffered/line buffered flag when setting the line buffered/unbuffered flag.
2016-12-15Fix some broken links in Cygwin FAQJon Turney
GNU no longer encourages the use of documentation mirrors, to avoid referring to obsolete documentation. Also www.fsf.org/manual/ is just a redirect to www.gnu.org/manual/ Links to using-utils.html #fragments are no longer correct as each utility is now a separate page, since 646745cb. indiana.edu seems to have moved XLiveCD information, without a redirect. Linking to clean_setup.pl on cygwin.com doesn't work, as direct downloads aren't allowed, so instead state where it can be found on a mirror. Signed-off-by: Jon Turney <jon.turney@dronecode.org.uk>

2016-12-14Rearrange RNG code slightlyCorinna Vinschen
In preparation of exporting getentropy/getrandom to userspace, rearrange code a bit: - Define RtlGenRandom in ntdll.h. - Drop calls to getentropy in favor of RtlGenRandom (fhandler_socket, fhandler_dev_random). - Add try/except blocks in fhandler_dev_random to return EFAULT rather than crashing if buffer pointer is invalid.

2016-12-13Fix incorrect path conversion on non-existent files on network sharesCorinna Vinschen
NtOpenFile/NtCreateFile on non-existent paths on network drives has a bug. Assuming a path Z:\dir\file. Further assuming that Z:\dir does not exist. The first NtOpenFile("Z:\dir\file") correctly returns STATUS_OBJECT_PATH_NOT_FOUND. Subsequent calls incorrectly return STATUS_OBJECT_NAME_NOT_FOUND. This appears to be some kind of caching behaviour. Waiting a while before repeating the call correctly returns STATUS_OBJECT_PATH_NOT_FOUND again. This patch works around the observed misbehaviour.

2016-12-13Check for .exe file in cygwin_conv_pathCorinna Vinschen
So far, when converting from POSIX to Windows notation, cygwin_conv_path fails to check for .exe suffix, so /path/foo did not return /path/foo.exe even if this file exists. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2016-11-24Self-contained pthread_spinlock_t for RTEMSSebastian Huber
Turn pthread_spinlock_t into a self-contained object. On uni-processor configurations, interrupts are disabled in the lock/trylock operations and the previous interrupt status is restored in the corresponding unlock operations. On SMP configurations, a ticket lock is a acquired and released in addition. See also: https://devel.rtems.org/ticket/2674 This implementation is simple and efficient. However, this test case of the Linux Test Project would fail due to call of printf() and sleep() during spin lock ownership: https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_spin_lock/1-2.c Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

2016-10-25Fix pdf build failure with texinfo 6.1.0Thomas Preudhomme
Hi, make pdf on Ubuntu 16.04 fail with: newlib/libc/libc.texinfo:9: Missing @endcsname inserted. After a lot of fiddling the reason appears to be the combination of concept and function index despite a lack of concept index entries. Arguably texinfo should not error in that case but here we are, newlib will fail to build its documentation on some systems because of this. Since libc.texinfo only contains function index entries this patch simply removes the combination of indices. It does the same for libm.texinfo which has concept index entries but no function index entries. Tested by running make pdf, make dvi, make info and make html successfully. libc.pdf appears to have only one index as expected. == Proposed commit message == Fix pdf build failure with texinfo 6.1.0 as provided in Ubuntu 16.04. Index combination in libc.texinfo and libm.texinfo fails because both file have only one type of index entries. Removing index combination is thus harmless and solves the problem. Is this ok for master? Best regards, Thomas
