2016-06-12Fix return value of fwrite when a 'hard' error occursJan Vangorp
When a 'hard' error occurs, fwrite reports that all data was written or buffered even if that is not the case. It should report how much data was actually written and buffered. Signed-off-by: Jan Vangorp <jan.vangorp_ext@softathome.com>
2016-06-12Fix infinite loop when fopencookie custom write returns 0 on errorJan Vangorp
The man page for fopencookie prescribes that custom write functions should return 0 on error (and should definitely not return a negative value) [1]. However, the uClibc implementation expects a negative return value in case of an error (libc/stdio/_WRITE.c). If the write function returns 0 on error, we drop into an infinite loop if the error persists. This patch wraps the user supplied write function such that a 0 return value is converted to -1. errno is first set to EAGAIN such that if the custom write function does not set errno in case of error, this is treated as a "soft" error. Custom write functions that cater towards uClibc and _do_ return a negative value are not affected. If no custom write function is supplied, set errno to EINVAL such that this condition is treated as a "hard" error. Previously the behaviour depended on whether the last error before the write happened to be a "hard" or a "soft" error.

2016-05-28ldso: Force disable -mlong-calls when compiling ldso for ARCAlexey Brodkin
Even though by default for ARC uClibc gets compiled with disabled long-calls user may provide UCLIBC_EXTRA_CFLAGS with "-mlong-calls". With this option uClibc will be successfully compiled but later it will fail in runtime because dynamic loader cannot deal with relocations at least very early on its start. In particular it will be seen as call to non-relocated symbol _dl_parse_dynamic_info() which ends-up as a segfault like this: ------------------------>8-------------------- potentially unexpected fatal signal 11.

2016-05-28sigaction: fix for THREADS_NATIVEBaruch Siach
Commit 9c4fce55a (nptl: remove sigaction, sigprocmask, and sigfillset from libpthread) removed pt-sigaction.c from the build to fix static build. However, since the libc sigaction is weak when HAS_THREADS is enabled, static build is not be affected. Tested for xtensa, x86, MIPS32 targets. Fixes nptl/tst-signal7. Moreover, commit 9193a76bb from the 0.9.33 branch has the right version.

2016-05-24microblaze: fix setjmp/longjmpWaldemar Brodkorb
Sync mostly with GNU libc implementation of setjmp/longjmp. Just generate PIC compatible code, so no difference for static builds are made. Add sysdep.h with some handy assembly macros used inside setjmp.S/__longjmp.S. This unbreaks dynamic linker support, first test suite run only shows 10 errors, which doesn't look so bad.

2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT.

2016-04-03Provide an alias to _obstack_freeAlexey Neyman
GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used, but the problematic code exists in 1.0.13 as well). The reason is that GDB release includes its own obstack implementation, but elides the code if <gnu-versions.h> declares a compatible obstack implementation in libc. uclibc-ng does claim compatible obstack interface (GDB expects version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)), however, uclibc-ng does not provide the _obstack_free symbol that is a part of the interface (glibc does provide this symbol). This later causes a link failure. The attached patch makes uclibc-ng enables an alias _obstack_free -> obstack_free. Signed-off-by: Alexey Neyman <stilor@att.net>
2016-03-31bits/byteswap-common.h: import recent headers from glibcAnthony G. Basile
On systems where uClibc doesn't provide an arch specific byteswap.h, we fall back on bits/byteswap-common.h. However, there is a bug in this header in the __bswap_constant_64(x) macro. If, for example, a double is passed, we get 'invalid operands to binary &' in which we mismatch a 'double' and 'long long unsigned int'. The newer glibc headers fix this and so we import them. Also, since the inclusion of byteswap.h is not appropriate for assembly code, we guard a portion of endian.h which uses byteswap.h from inclusion in any assembly. This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big endian PowerPC. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
