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>

2016-08-05sunrpc: 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.

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.

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>

2016-06-24inet/resolv: Try search domains first for unqualified namesIngo van Lil
When resolving an unqualified host name, the resolver tries the original name first before appending the domains from the search list. If a TLD with the same name exists, the query will succeed (but yield no A record) and the resolver will return HOST_NOT_FOUND without trying the search domains. This patch changes the lookup order for unqualified host names (without dots) to try the search domains first and the original name last. Signed-off-by: Ingo van Lil <inguin@gmx.de>
2016-06-23ARC: Enable shared crt1Vineet Gupta
Currently crt1 takes address of functions (main,_init,_fini) directly which doesn't generate truely position independent code, but zero based values instead. e.g. | __start: | ... | add_s r2,sp,0x4 | mov_s r0, main generates to | 000156ec <__start>: | ... | 156f4: add_s r2,sp,0x4 | 156f6: mov_s r0,0x15f7c | ... | 00015f7c <main>: | 15f7c: push_s blink This works just fine for the normal (non PIE) dynamic executables since they are loaded at address 0. However this is not true for PIE executables. So for Scrt1 we use a true position independent way when taking function addresses.

2016-06-23ARC: remove deprecated -msoft-float from CFLAGSAlexey Brodkin
"-msoft-float" makes no sense for ARC because there's no such thing as "-mhard-float" on ARC. Instead we use our own "-mfpu=XXX" option when a particular floating-point related HW feature is enabled in the ARC core. We used to live with that phony option for quite some time but with migration to newer GCC following warning now appears: -------------------->8----------------- arc-linux-gcc: warning: ‘-msoft-float’ is deprecated cc1: warning: ‘-msoft-float’ is deprecated [enabled by default] -------------------->8----------------- And that warning gets printed for each invocation of gcc with the option in question, which makes compilation output barely readable. So we disable that phony option for ARC now.

2016-06-21inet/getaddrinfo: fix AF_V4MAPPED behavior for non IPv6 host resolutionWenzel, Alexander
When trying to resolve a hostname by getaddrinfo() using some specific settings, it will always return -EAI_NONAME (Name or service not known). To reproduce this behavior, you need to request an IPv6 address with the additional AF_V4MAPPED flag set from an non IPv6 capable hostname. If you choose a IPv4/IPv6 capable hostname like google.com, everything works fine. This patch is more or less a port [1][2] from the glibc and their behavior for the AF_V4MAPPED flag. To test the bug you can use the following snippet. ---- 8< ---- int ret; struct addrinfo* result; struct addrinfo hints; memset(&hints, 0, sizeof(struct addrinfo)); hints.ai_family = AF_INET6; hints.ai_flags = AI_V4MAPPED; ret = getaddrinfo("test.com", NULL, &hints, &result); printf("getaddrinfo(): %i", ret); ---- 8< ---- [1] https://sourceware.org/git/?p=glibc.git;a=commit;f=sysdeps/posix/getaddrinfo.c;h=925c3c5c71596c02f7e58a0ffcdcaae44eb065c1 [2] https://sourceware.org/git/?p=glibc.git;a=commit;f=sysdeps/posix/getaddrinfo.c;h=28977c2c1acb789660ad47e0d88e42486059c916 Signed-off-by: Alexander Wenzel <alexander.wenzel@qsc.de>
