2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance

2016-09-19test: disable regex testsWaldemar Brodkorb
The time to run the tests is very high and always subtests are failing. We need to fix the subtests and see how to reduce the time the test is running. At the moment it blocks my regression testing to much.
2016-09-19elf-{fdpic, dsbt}.h: avoid void pointer's subtractionRahul Bedarkar
elf-fdpic.h or elf-dsbt.h is included by link.h. When C++ program includes <link.h>, we get following build failure. ../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)': ../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void' void pointer addition and subtraction is not allowed in C++ as it has undetermined size, however in C with language extension it is possible because sizeof void is treated as one byte. Instead of performing subtraction on void pointers, typecast it to char* first. This build failure is detected by Buildroot autobuilder. http://autobuild.buildroot.net/results/a10/a10ed48e6eb8411a3d8372f57c05fd11130da0e0/ Signed-off-by: Rahul Bedarkar <rahul.bedarkar@imgtec.com>

2016-08-27ARC: Fix max ULP for cosine testEugeniy Paltsev
Max ULP for "cos (M_PI_6l * 2.0) == 0.5" in "test-double" sub-test is set to "0" for ARC. It causes "test-double" test failure. I realized that this sub-test on ARM gets completely same results. But it doesn't fails on ARM because max ULP is set to "1" for ARM. I am wondering, if it was done for any special reason? Otherwise, set max ULP for "cos (M_PI_6l * 2.0) == 0.5" test to "1" instead of "0" for ARC. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

2016-08-17ARC: Support syscall ABI v4Vineet Gupta
The syscall ABI includes the gcc functional calling ABI since a syscall implies userland caller and kernel callee. The current gcc ABI (v3) for ARCv2 ISA required 64-bit data be passed in even-odd register pairs, (potentially punching reg holes when passing such values as args). This was partly driven by the fact that the double-word LDD/STD instructions in ARCv2 expect the register alignment and thus gcc forcing this avoids extra MOV at the cost of a few unused register (which we have plenty anyways). This however was rejected as part of upstreaming gcc port to HS. So the new ABI v4 doesn't enforce the even-odd reg restriction. Do note that for ARCompact ISA builds v3 and v4 are practically the same in terms of gcc code generation. This change is dormant for now (gcc 4.8.x based tools) and will only kick in with switch to gcc 6.x based tools. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-08-16linuxthreads: install libpthread_nonshared.aWaldemar Brodkorb
This is useful to build native gcc on targets supporting Linuxthreads instead of NPTL.

Fix a regression introduced by commit 0550ecce0e6580c5ad34e9a9a39ff18ccf8774f9 Reported by Buildroot developers. Embedded test must be extented to ARMv7 thumb2 builds to find such regressions next time. It wasn't triggered by a cortex-m4 ARM noMMU build.
2016-08-05sunrpc: Do not use alloca in clntudp_callWaldemar Brodkorb
CVE-2016-4429: The call is technically in a loop, and under certain circumstances (which are quite difficult to reproduce in a test case), alloca can be invoked repeatedly during a single call to clntudp_call. As a result, the available stack space can be exhausted (even though individual alloca sizes are bounded implicitly by what can fit into a UDP packet, as a side effect of the earlier successful send operation).

2016-07-31ARC: Update relocation syntax for old-thread model codeAndrew Burgess
This commit reverses a change introduced in commit 20554a78a9bba that split some of the ARC code into two based on whether uClibc was configured with native threads or not. The native thread code was updated to use the relocation syntax of modern binutils, while the non-native code path used a syntax only accepted in older versions of binutils. The problem with this is that the choice of old binutils or not is orthogonal to the choice of native threads or not, and so, inevitably a user with a recent version of binutils can make the choice to configure uClibc with non-native thread support, and run into code that will not assemble. The solution is either to abandon support for the old tools completely, or to add a new compile time flag for ARC that is set when the version of binutils being used is old; this new flag would allow the old relocation structure to be selected. In this commit I have simply dropped support for older versions of the tools.
2016-07-31arc: clone: Simplify CLONE_THREAD detectionAlexey Brodkin
This change was inspired by similar change in glibc: https://sourceware.org/git/?p=glibc.git;a=commit;h=0cb313f7cb0e418b3d56f3a2ac69790522ab825d Current Linux kernel requires CLONE_VM to be set with CLONE_THREAD otherwise returning -EINVAL, see man clone2. This means we don't need to check for both CLONE_THREAD and CLONE_VM instead we may simplify code a lot and just check 1 bit (CLONE_THREAD).

2016-07-31arc: clone: Fix CLONE_THREAD detectionAlexey Brodkin
For thread group case (CLONE_THREAD), the cached PID of new process/thread need not be reset. The old logic to decide that was flawed as it would be true only for exact combination of CLONE_THREAD + _VM, but would fail for CLONE_THREAD + _VM + _xyz. More detailed tear-down of current and new code below. Current implementation is: --------------------->8-------------------- ; r12 contains clone flags mov_s r2, CLONE_THREAD_N_VM; r2 contains bit mask and_s r2, r2, r12 ; r2 contains bit mask AND clone flags ; but r12 still contains the same flags brne r2, r12, .Lgo_thread ; here we compare modified mask with ; flags as they were and skip pthread TID/PID ; setup if r2 != r12 which happens all ; the time except clone flags were ; exactly CLONE_THREAD | CLONE_VM --------------------->8-------------------- New implementation is: --------------------->8-------------------- ; r12 contains clone flags mov_s r2, CLONE_THREAD_N_VM; r2 contains bit mask and_s r12, r12, r2 ; r12 contains clone flags AND bit mask ; i.e. we did mask all flags except ; CLONE_THREAD and CLONE_VM breq r2, r12, .Lgo_thread ; here we compare masked flags with ; target mask and if they match we skip ; pthread TID/PID setup --------------------->8-------------------- Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Acked-by: Vineet Gupta <vgupta@synopsys.com>
2016-07-31arc: clone: Recover PID correctlyAlexey Brodkin
Caught by tst-getpid1 test from uClibc's test-suite. It looks like original implementation was not correct. The code in question is supposed to recover PID of the new thread. And by no means that could happen with clone() syscall while getpid() does exactly this.
