* Add missing headers to fix implicit function defnsPat Pannuto2017-01-164-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few files were missing headers for memset/malloc, likely missed because the files don't directly call the functions, rather they come in via macros in libc/include/sys/reent.h: #define _REENT_CHECK(var, what, type, size, init) do { \ struct _reent *_r = (var); \ if (_r->what == NULL) { \ _r->what = (type)malloc(size); \ #define _REENT_CHECK_ASCTIME_BUF(var) \ _REENT_CHECK(var, _asctime_buf, char *, _REENT_ASCTIME_SIZE, \ memset((var)->_asctime_buf, 0, _REENT_ASCTIME_SIZE)) Without these fixes, implicit function signatures are provided, which gcc warns could cause aliasing issues down the line: ../../../../../../../newlib-2.5.0/newlib/libc/time/asctime.c:62:3: warning: type of 'memset' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: return value type mismatch _PTR _EXFUN(memset,(_PTR, int, size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: 'memset' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/time/asctime.c:62:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/time/lcltime.c:58:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/string/strsignal.c:70:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used Including the proper headers elminates the implicit function signatures and these warnings.

* Always try to write complete incoming buffer on pipes and fifosCorinna Vinschen2017-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | This patch fixes the following problem: Commit 9636c426 refactored the pipe code especially to make sure to call WriteFile only with chunks matching the maximum atomic write count. This accidentally introduced a small change in behaviour on blocking pipes due to the success case falling through into the error case. Rather then writing atomic chunks until all bytes are written, the code immediately broke from the loop after writing the first chunk, basically the same as in case of non-blocking writes. This behaviour is not compliant to POSIX which requires "Write requests to a pipe or FIFO [...] * If the O_NONBLOCK flag is clear, a write request may cause the thread to block, but on normal completion it shall return nbyte."

* rename: Refactor "new file already exists and rename fails" caseCorinna Vinschen2017-01-121-20/+27
| | | | | | | | | | | | | | | | | | | | | | | If newfile already exists and is in use, trying to overwrite it with NtSetInformationFile(FileRenameInformation) fails exactly as if we don't have the permissions to delete it. Unfortunately the return code is the same STATUS_ACCESS_DENIED, so we have no way to distinguish these cases. What we do here so far is to start a transaction to delete newfile. If this open fails with a transactional error we stop the transaction and retry opening the file without transaction. But, here's the problem: If newfile is in use, NtOpenFile(oldfile) naturally does NOT fail with a transactional error. Rather, the subsequent call to unlink_nt(newfile) does, because there's another handle open to newfile outside a transaction. However, the code does not check if unlink_nt fails with a transactional error and so fails to retry without transaction. This patch recifies the problem and checks unlink_nt's status as well. Refactor code to get rid of goto into another code block. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* FAST_CWD: adjust the initial search scopeJohannes Schindelin2017-01-121-2/+2
| | | | | | | | | | | | A *very* recent Windows build adds more code to the preamble of RtlGetCurrentDirectory_U() so that the previous heuristic failed to find the call to the locking routine. This only affects the 64-bit version of ntdll, where the 0xe8 byte is now found at offset 40, not the 32-bit version. However, let's just double the area we search for said byte for good measure.

* Fix incorrect cast in nano mallocJoe Seymour2017-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in nano-mallocr.c, chunks of heap are represented in memory as a size (of type long), followed by some optional padding containing a negative offset to size, followed by the data area. get_chunk_from_ptr is responsible for taking a pointer to the data area (as returned by malloc) and finding the start of the chunk. It does this by assuming there is no padding and trying to read the size, if the size is negative then it uses that as an offset to find the true size. Crucially, it reads the padding area as a long. nano_malloc is responsible for populating the optional padding area. It does so by casting a pointer to an (int *) and writing the negative offset into it. This means that padding is being written as an int but read as a long. On msp430 an int is 2 bytes, while a long is 4 bytes. This means that 2 bytes are written to the padding, but 4 bytes are read from it: it has only been partially initialised. nano_malloc is the default malloc implementation for msp430. This patch changes the cast from (int *) to (long *). The change to nano_malloc has has been observed to fix a TI Energia project that had been malfunctioning because malloc was returning invalid addresses. The change to nano_memalign is based entirely on code inspection. I've built and tested as follows: Configured (gcc+newlib) with: --target=msp430-elf --enable-languages=c gcc testsuite variations: msp430-sim/-mcpu=msp430 msp430-sim/-mcpu=msp430x msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either msp430-sim/-mhwmult=none msp430-sim/-mhwmult=f5series My testing has shown no regressions, however I don't know if the gcc testsuite provides sufficient coverage for this patch? I don't have write access, so if this patch is acceptable after review, I would appreciate it if someone would commit it for me.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.
